    专利说明:

    The invention relates to the field of gas distribution and gas distribution assemblies, in particular medical gas. It concerns more particularly the management of the practical information relating to these gas distribution assemblies, and in particular their autonomy for the management of stocks.
    Industrial and medical gases are commonly packaged in gas containers, typically cylinders or gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or a tap to integrated regulator, also called RDI, to control flow and pressure of the delivered gas.
    In order to protect this valve block, it is common to arrange at the level of the neck of the gas bottle and around said valve block, a protective cover forming a protective shell around said valve block.
    As part of an integrated pressure reducer valve, it is known to report, particularly on the cowling, information immediately visible to the user and relating to the gas delivered by the bottle (type of gas, pressure, flow ...) . For this purpose, it is possible to use in particular a gas filling indicator device, such as a pressure gauge indicating the pressure of the gas, or a flow indicator device.
    There are known gas pressure indicating devices which consist of needle gauges or manometers with digital reading, in particular arranged in the lower part of the tap. On the same gas distribution assembly, it is known to have a flow indicator device, which takes for example the form of a rotary wheel whose displacement generates a change in the gas flow at the outlet of the valve, presenting in front of a mark visible by the user an encrypted value representative of the corresponding flow.
    The positioning of these devices in the lower part of the tap, due to technical constraints, including the fact that the protective casing surrounds the valve block or RDI, makes it often difficult or not easy to read the indications given by the device
    Furthermore, there are known integrated electronic devices that collect data relating to the filling of the bottle and which present them to the user, so that it can avoid gas supply disruptions, particularly detrimental in the hospital environment. These integrated electronic devices are expensive and proper management of the gas supply of a hospital environment, that is to say stocks of gas distribution assemblies, requires each bottle to be equipped with such integrated electronic devices. to be efficient.
    The present invention is in this context and aims to provide a method of inventory management gas distribution sets that is easy to implement without requiring heavy investments to change the entire fleet of gas distribution sets d a hospital for example.
    In this context, the subject of the invention is a method for calculating the autonomy of a gas distribution assembly comprising a container containing gas and equipped with at least one indicator device for filling the gas, as a a gas pressure indicating device and a gas flow indicator device at the outlet of the container, during which a step of recovering at least one identification information of the container and / or of the gas used is carried out; a step of acquiring at least one image, via a communicating mobile device, for recovering a first data item on a value indicated by the gas filling indicator device and a second data item on a value indicated by the flow indicator device. Said at least one acquired image and said at least one retrieved identification information is communicated to a calculation module configured to derive a corresponding autonomy information from said gas distribution assembly, said calculation module including at least one means of image processing.
    Thus, information can be collected on the autonomy of a gas container when it is not accessible by the user, via computing means embedded in the mobile device communicating, or all at less present on a server in connection with the communicating mobile device, and one can capitalize on this digital information by transferring it to a stock management module of such gas distribution sets.
    According to various features of the invention, taken alone or in combination, it can be provided that: - the simultaneous recovery of the first data and the second data by the acquisition of a single image; the calculation module and the image processing means can be embedded in the communicating mobile device; the communicating mobile device can be chosen among smart phones, also known as smartphone, or even among the tablets. the processing means analyze in the at least one acquired image a two-dimensional barcode associated with the gas filling indicator device; and / or the processing means analyze in the acquired image, by character recognition, an encrypted value carried by a rotating wheel of the flow indicator device. The step of retrieving at least one identification information and the step of acquiring the first and second data can be performed in one step, or it is conceivable that the information retrieval step of identification is a preliminary step in the acquisition step of the first and second data.
    In the latter case, the information retrieval step may comprise a step of pairing communicating mobile device and the considered gas distribution assembly; the pairing step can be performed by reading by the mobile device communicating a recognition chip, RFID or NFC type, embedded on the gas container.
    As a variant, provision may be made for the retrieval of identification information to be done by an input of manual data from the user, or by acquisition of an image, possibly the same as that of recovering the first and second data. The preliminary pairing step can generate the opening or download on the communicating mobile device of a parameter processing application associated with the gas distribution assembly, and it can further generate the recovery of a positioning information of the communicating mobile device. The user can receive a request to perform the image acquisition if additional information is needed after the preliminary pairing step. The image acquisition can be carried out via one or more photographs and / or via a video.
    It is also possible to acquire information on the temperature of the gas container.
    It can further be provided that a user and / or control center warning step is generated when the autonomy value of the gas distribution assembly is below a determined threshold value. . The invention also relates to a method of inventory management of gas distribution sets, on the basis of an autonomy information of at least one of these sets, obtained via the calculation method as presented. above, said autonomy information being transmitted to a stock management server.
    Location information of these gas distribution assemblies will advantageously be collected during the steps for calculating autonomy, in order to provide said location information to a control unit managing the inventory. The invention further relates to a gas distribution assembly comprising a gas container, a valve block attached to the container, and a gas flow control member having a support surface of a flow information of the gas, said assembly further comprising a manometer arranged to make visible information relating to the filling, and in particular to the pressure of the gas contained in the container.
    According to one aspect of the invention, the manometer screen is disposed near the support face of the information relating to the gas flow carried by the regulating member.
    In this context, it can be provided that: - the screen of the manometer and the support surface of the information relating to the gas flow carried by the regulating member are arranged opposite the container relative to the valve block; the manometer and the support face the information relating to the flow of gas extend in substantially parallel planes with respect to each other; - A handle is disposed at the top of the container, covering the valve block, the pressure gauge and the gas flow control member, said handle incorporating a recognition chip; - The handle has in its center a receiving area of a mobile device communicating; the receiving zone may extend in a plane substantially parallel to the planes in which the manometer and the support face extend the information relating to the gas flow rate; the orientation of the plane in which the manometer extends advantageously has an angle of 45 ° with respect to the vertical; - the pressure gauge screen has a two-dimensional barcode and a fill indicator in the form of a needle; - the gas container is a gas cylinder. The invention also relates to an application for managing parameters associated with a set of distribution gases implemented by a communicating mobile device, which can be launched or downloaded during the reading of a recognition chip carried by the set of gas distribution.
    This application can in particular determine the information recorded on the gas distribution assembly to define whether a container autonomy information is directly exploitable, and make a request for image acquisition by the user in the opposite case, in order to start a calculation method as presented above. Other features and advantages of the present invention will appear more clearly with the aid of the description and the drawings, in which: FIG. 1 is a partial front view of a gas distribution assembly, in particular centered on the part top of a gas container and on the associated protective cover; and - Figure 2 is a schematic representation of different components of the dispensing assembly of Figure 1, according to the cutting plane A-A illustrated in Figure 1; FIG. 3 is a schematic representation of the screen of a mobile device communicating during an image acquisition step of a range calculation method according to the invention; and FIG. 4 is a flowchart illustrating an embodiment of calculation of the autonomy process according to the invention, in particular in its application in a method of inventory management of gas distribution assemblies.
    A gas distribution assembly 1 according to the invention comprises a gas container 2, here a gas cylinder, on a neck of which is fixed by screwing a valve block (not visible), namely a valve with or without built-in expansion valve. A protective cover 4 is arranged at the top of the gas cylinder, covering the tap, in particular to protect it against shocks.
    The gas bottle 2 has by way of non-limiting example a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (water equivalent).
    The protective cover 4 comprises a casing body forming a protective shell around an internal volume sized to receive the valve block.
    Moreover, it is surmounted by a handle 6 designed to be handled by a user. The handle 6 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is connected to the protective cover 4 here by two uprights 8.
    The handle is preferably arranged perpendicularly or almost perpendicular to the longitudinal axis along which the bottle 2 and the hood 4 extend.
    The handle 6 has an elongate shape, whether rectilinear or curved, between the two uprights 8, and it has on a first face 10 a cavity 12 whose dimension along this elongated shape is substantially equal to the width of a mobile device 13 communicating, so as to form substantially in the center of the handle a receiving area of the communicating mobile device. It is indeed noticeable that, according to the invention, the bottle can interact with the user via a communicating mobile device such as a smartphone or smartphone, or even a tablet, tactile or not, and this in different ways, as some will be presented below.
    A recognition chip 14, type NFC (acronym derived from the English Near Field Communication, for a near-field communication function), or RFID type (acronym taken from the English Radio Frequency Identification) is housed in the handle , and for example on the second face, opposite to the first face 10, being advantageously centered in line with the cavity 12, so that the mobile device communicating can collect information recorded in the recognition chip.
    The protective cover 4 is made of a material of the polymer and / or metal type, preferably of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA ...
    The protective cover 4 has a mounting base 15 at the top of the bottle, in particular by means of a fastening ring 16 optionally equipped with a device for fastening the gas distribution assembly to a cylinder. support, such as a bar of hospital bed or stretcher.
    The mounting base 15 is extended, opposite the bottle, by an intermediate portion 18 having an orifice 20 through which opens a gas outlet connection 22, for withdrawing the gas delivered by the valve. The flow of the gas passing through this connection is controlled by a gas flow control member 24, such as a rotary wheel. The gas distribution assembly according to the invention is arranged so that the protective cover has on its front face 25, that is to say the face visible by the user at the same time as the first face 10 of the handle, a light 26 through which is made visible an information support face 27 of the gas flow control member on which is represented a value representative of the flow 28 (this value being here equal to 5 in the figures 1 and 3). The displacement of the regulating member modifies the flow rate of the outgoing gas and consequently has inside the light 26 a value representative of the flow rate. In the illustrated case, the light 26 is formed by cutting a portion of the edge defining the orifice 20, to the right of the gas outlet fitting, in the upper part of the protective cover. In other words, the gas outlet connection is disposed between the bottle and the gas flow indicator device having the value representative of the flow 28 and the light 26 by which this value is visible to the user. In order to facilitate the reading of the representative flow rate value by the user, the information support face 27 extends in a plane inclined with respect to a vertical plane perpendicular to the axis of the gas outlet connection. inclination being substantially equal to 45 °.
    The protective cover further has an upper portion 29 extending the intermediate portion 18 away from the connector, opposite the mounting base 15, which comprises in particular on its front face 30 a screen of a manometer 32, forming device filling indicator, in particular pressure indicator, of the gas remaining in the bottle. The manometer screen may advantageously comprise a two-dimensional bar code, for example a QR code tag (acronym for Quick Response), or a visual distinctive element, this allowing as will be described hereinafter the identification of an information item. pressure of the gas remaining in the bottle, in particular by allowing to detect the orientation of the pressure indicator in the form of a needle.
    It could be envisaged that this upper part carries an electronic display screen, not shown here, and for example an LCD screen, configured to display one or more information selected from the time, the date, the flow of gas delivered by the tap. , the pressure of the gas in the bottle, the autonomy of the electric source feeding this screen, the ambient temperature, an alarm, the name of the care establishment or other, etc ... We understand that the screen, so to be able to display this information, would be associated with one or more sensors, such as one or more pressure or flow sensors, and information processing means, for example a microprocessor associated with one or more algorithms, so that that the information may possibly be stored in an information storage memory, and finally transmitted, via a suitable connector, to the electronic screen on which they can be displayed.
    It is notable that at least the front face 30 of the upper part of the protective cover, carrier of the pressure gauge 32, and the information support face 27 extend in substantially parallel planes and, as has been specified previously, inclined relative to a vertical plane of an angle substantially equal to 45 °.
    As will be understood below, such an arrangement makes it possible to acquire in a single image 33, in a manner sufficiently clear to be exploitable subsequently by image processing means, both the information relating to the bit rate. outgoing gas and the information relating to the pressure of the gas remaining in the bottle.
    In order to exploit the images acquired, the mobile device communicating comprises a calculation module, in which image processing means make it possible to analyze the images acquired and to transmit data relating to the flow and the pressure of the gas in the bottle. If it is advantageous that this calculation module and the associated image processing means are embedded in the mobile device communicating, it may be noted that they may be present in an external server with which the mobile device is able to communicate.
    In an advantageous embodiment, in particular illustrated in FIG. 2, the receiving zone of the communicating mobile device formed in the handle 6 has a bottom wall which extends in a plane substantially parallel to the planes in which it extends. the manometer and the support face of the information relating to the flow of gas. The handle is disposed at the top of the bottle, covering the valve block, the pressure gauge and the gas flow control member. Thus, it may be possible to acquire in a single image, sufficiently sharp for processing by the calculation module, both the information relating to the flow rate and the gas pressure and the identification information carried by the chip. recognition lodged in the handle.
    In this advantageous configuration in particular, the screen of the manometer 32 is arranged in the upper part 29 of the bottle so that its window is flush with the front face 30, it being understood that the window could without departing from the context of the The invention is slightly recessed from the front face inside the protective cover or, conversely, slightly protruding outwardly with respect to the front face.
    It is understood that the arrangement of the indicator devices makes it considerably easier for the user to read the information delivered by these devices, and more particularly, in the context of the method for calculating the autonomy of the bottle by means of a communicating mobile device according to the invention, the acquisition of an image 33 comprising these various information, limiting as much as possible the number of gestures to be performed by the user for such an acquisition.
    Thus, the screen of the manometer forming the pressure indicator device is disposed near the support surface of the information relating to the gas flow carried by the regulating member. And they are arranged in substantially parallel planes. In addition, the pressure gauge and this support face are arranged on the same side of the gas distribution assembly with respect to the gas outlet connection, so that the tube attached to this connection does not interfere with the acquisition of information on the same image. In other words, the screen of the manometer and the support surface of the information relating to the gas flow carried by the regulating member are arranged opposite the bottle relative to the valve block and the associated fitting. .
    A gas cylinder as just described is particularly suitable for use in a medical environment. In particular, it is suitable for storing any medical gas or gas mixture, in particular of oxygen, air, N 2 O 2, He / O 2, NO / nitrogen or other type.
    A gas distribution assembly such as has just been described in an exemplary embodiment allows the implementation of a method of calculating autonomy, particularly useful in particular in inventory management, and may also be useful in an application in hospitals to determine whether a particular gas distribution set can be used for a particular patient.
    An example of a method for calculating autonomy according to the invention will be described below.
    In a first phase 100, the user retrieves at least one identification information from the bottle 2 and / or the gas by initiating an interaction with the bottle by reading the recognition chip 14 via its communicating mobile device 13 and a adequate reading device embedded on the mobile device. The user approaches his mobile device 13 of the bottle 2, and more particularly of the zone in which the recognition chip 14 is integrated, namely the handle 6 of the bottle.
    One or more actions can then be triggered.
    It is understood that to start the interactions with the bottle, it is first necessary to open on the mobile device communicating 13 a dedicated application. This may be automatic or alternatively be performed manually by the user at the approach of the gas distribution assembly which he wants to check the autonomy.
    It is understood that the automatic triggering (step 104) of an application dedicated to the mobile device communicating can either consist of an opening of the application when it is already present on the device, or an initial download on the network if it is not present on the mobile device at the time of reading the recognition chip (step 102). This can be done in particular by reading in the recognition chip a reference address to download on an application download platform.
    This application advantageously allows the presentation of information that the mobile device communicating is likely to collect by analyzing the memory of the recognition chip. The user can thus know via the application a plurality of necessary and / or available information about the bottle 2, such as the model, the year of entry into circulation, the type of gas used, etc. The communicating mobile device 13 may also acquire dynamic data from sensors associated with the bottle such as temperature (step 106), pressure or other parameters, by retrieving data already recorded in the recognition chip 14 or by recognizing the position of buttons relating to adjustment means.
    The recovery of at least one identification information of the bottle and / or a gas identification information can be done by reading, still using the mobile device communicating 13, a code- two-dimensional bars 34 or a distinctive visual pattern of the recognition chip 14 RFID or NFC type, and the user will receive a request to that effect, that is to say a request for it retrieves the information by another way, coming from the communicating mobile device. This could be useful for example when no RFID or NFC type of recognition chip is embedded on the bottle or when it is required by the application to rapidly scan several bottles, in particular as part of a management application. stock.
    Scanning of the recognition chip (step 102) can be performed by a wireless link, for example by the use of a radio protocol of the Bluetooth type, between the mobile device communicating and the electronics of the bottle, and this connection allows the exchange of data such as the values of the sensors.
    The scanning of the recognition chip (step 102) and the pairing of the communicating mobile device and the bottle (step 104) may allow the triggering of a series of sensor usage algorithm for detecting the position of the communicating mobile device (step 108). This can notably be achieved by using the internal functions of the communicating mobile device, and in particular the geolocation functions, or by using fixed beacons arranged in the room in which the gas distribution assembly is arranged, said beacons being able to example communicate with the mobile device via a wireless communication type Bluetooth. It may be considered alternatively to have to communicate by contact with these tags, for example by scanning a complementary code such as a two-dimensional QR barcode disposed near the bottle.
    Whatever the variants, this pairing phase of the communicating mobile device and the bottle allows the recording in the mobile device of all the relevant data that it has captured.
    In a second phase 110, the user must actively participate to collect additional data. In particular, and especially in the case where the information collected during the first step 100 is insufficient (test step 105), the user is invited to take one or more images 33, or a video, of the bottle in a step 112 of acquiring images via the camera or camera of the communicating mobile device 13.
    Image processing means are configured, in an image analysis and processing step 114, to process the images and / or video acquired by the user via the communicating mobile device. These image processing means may consist of an application present on the mobile device or a software embedded on a computer remote from the mobile device. In the latter case, the user will be able to transfer the images to be processed by a wired connection between the mobile device and the computer.
    The image processing means are configured to derive from the images and / or videos acquired additional information on the bottle and may in particular consist of means configured to detect data such as: the pressure indicated by the needle pressure gauge, in detecting the position of the needle in space by a marker associated with a dimensional bar code, for example using the method described in WO2015136207 (et al. 114a); the flow rate indicated by the information carrier face of the flow control device, using appropriate optical recognition software, of character recognition type, or a correlation algorithm with prerecorded reference images (step 114b); the position of an on / off switch of the flow indicator device.
    It will be understood that the analysis and image processing steps 114a and 114b are based on a mechanical support detection, but that without departing from the context of the invention, it would be possible to analyze the image acquired to detect the values presented. by one or more digital electronic gauges. Here it is described that the step of retrieving identification information, namely the steps of the first phase 100, by reading the recognition chip in the example illustrated above, is a preliminary step to the step of acquiring the first and second data relating to the pressure and flow rate of the gas in the bottle, that is to say the steps of the second phase 110, but it will be understood that the recovery of identification information and the acquisition of the first and second data can be performed simultaneously by the same image, this simultaneity being authorized by the specific arrangement of the bottle as presented above.
    The data collected automatically or by a user action can be stored locally in the mobile device communicating with the user, it being understood that they can also be stored on an external server in a remote location to provide data for example to a gas supplier or gas distribution assembly, therefore able to respond quickly to the needs of users, for example hospitals.
    The image processing means 116 form part of a calculation module 118 configured to derive from this image a corresponding autonomy information 120 of the gas distribution assembly. The analysis of the image 33 makes it possible, on the one hand, to determine a pressure value of the gas remaining in the bottle, by deciphering the first part of the acquired image 33a containing the information carried by the filling indicator device of the gas, on the other hand a flow rate of the gas at the outlet of the bottle, by deciphering the second part of the acquired image 33b containing the information carried by the gas filling indicator device, and the calculation module can on this basis calculate the remaining time for the gas distribution under these flow conditions. The calculation may advantageously be completed by a temperature information obtained by a sensor associated with the bottle or the room in which the bottle is disposed. The autonomy information determined by the calculation module is then displayed on the communicating mobile device, in order to give an indication to the user, and / or it is sent to an inventory management module 124 via a user interface. communication 122, in particular to allow the implementation of an automatic replenishment 126 of the bottle when the autonomy value is below a determined threshold. It is understood that in this case, the present invention allows the user to more effectively manage the local stock of gas distribution sets.
    Such a calculation can further enable action 128 on the distribution parameters defined for this gas distribution assembly, in particular by encouraging the user to modify the value of an actuator such as a flow regulator.
    A possible application of the invention will now be described in more detail for a gas distribution assembly 1 in which a bottle 2 is equipped with an NFC type recognition chip 14, a first wireless link beacon, type
    Bluetooth, connected to a temperature sensor and therefore capable of returning a temperature information of the gas contained in the bottle, a pressure gauge needle 32 forming a pressure indicator device, and a flow control member 24 with a rotary control wheel.
    There is also provided a second wireless link beacon, independent of the bottles, in each room in which a bottle can be stored, for example in each of the storage rooms of a hospital. The user has his mobile device communicating 13, and by way of example in what follows his smartphone, in the cavity 12 forming reception area in the handle 6 of the gas distribution assembly 1, and the smartphone and the Associated applications digitize the recognition chip 14 so that a pairing is generated between the smartphone and the bottle. In a first phase 100, a first step of recovering information from the bottle and / or the gas is performed, and a connection is generated with the first tag associated with the bottle via a wireless Bluetooth type connection in order to acquire the temperature of the bottle.
    A management application is started and it configures the smartphone to try to discover if one or more second tags are in its wireless communication zone. If such second tags are detected, the smartphone can record a location and ambient temperature specific to the paired bottle. In the absence of a second detectable beacon, the use of the geolocation function of the smartphone can be used to acquire the geolocation coordinates of the smartphone.
    When the pairing is completed, by reading the recognition chip, the application sends a request to the user for it directs the smartphone camera towards the flow and pressure indicator devices, in order to achieve step of acquiring at least one image of the manometer and the flow control device, so that computing means associated with the smartphone can determine a first data on a value indicated by the gas pressure indicating device and a second datum on a value indicated by the flow indicator device.
    In particular, it is sought to simultaneously recover the first datum and the second datum by acquiring a single image, it being understood that without going beyond the context of the invention, it will be possible to recover the first and second data by I acquired successively or by video.
    Advantageously, according to the invention, the planes in which the information carriers of the first and second data extend are substantially parallel to each other.
    The manometer has on its screen, in the vicinity of the needle, a two-dimensional bar code, so that by using a method described in WO2015136207, the smartphone acquires the identification of the bottle and the pressure value. gas in the bottle.
    In the same image, the calculation module determines the position of the flow selector by processing the image with a character recognition reader.
    As has been mentioned above, and as can be seen in FIG. 2 in particular, the plane PI in which the information carrier of the first datum extends, that is to say the support face of 27, and the plane P2 in which extends the information carrier of the second datum, that is to say the screen of the manometer 32, are substantially parallel to each other and they advantageously extend according to a angular orientation relative to the vertical substantially similar to the angular orientation relative to the vertical of the plane P3 containing the bottom wall of the cavity 12 forming receiving housing of the smartphone 13. Thus, when the user receives a request to take photo of the flow and pressure indicator devices, following the reading of the recognition chip, the smartphone is already oriented as needed to allow a sharp image, the user having everything To move the phone in the same plane to clear it from the receiving slot.
    It will be understood that the image processing for determining the value relating to the pressure and the image processing for determining the value relative to the flow rate are advantageously performed simultaneously on the basis of the same image, but that one could without out of the context of the invention successively treat two separate images or a video.
    The smartphone stores in its memory the identification information of the bottle, the ambient temperature and / or the temperature of the bottle, the pressure of the gas remaining in the bottle, the position of the flow selector, the geolocation of the smartphone and the time the scan was done.
    With these data, if the bottle is used, the smartphone allows the calculation of the precise autonomy of the bottle, and it can set up an alarm to warn the user when a small amount of gas in the bottle is considered critical, especially in the case of application in a hospital, where it is appropriate that there is sufficient air for the correct care of the patients. The threshold value beyond which an alarm is generated may, if necessary, depend on a patient identification parameter 126 to which the gas will be administered.
    The connection with the second wireless beacon can be used to update the autonomy of the bottle in case of change of the ambient temperature for gases that are sensitive to temperature, for example acetylene.
    If the bottle is not in use, ie the smartphone has detected that the flow selector is in the "zero" or "off" position, the smartphone can simply generate a request to the user. user to know if the bottle is intended to be used or to be stored, in order to refine inventory management.
    The foregoing description clearly explains how the invention makes it possible to achieve the objectives which it has set itself and in particular to propose a gas distribution assembly making it possible, by an appropriate calculation method, for the user to recover a data autonomy of this distribution set easily exploitable by a server and an inventory management module, especially in the case of use of such gas distribution sets in hospitals.
