    [0001] The invention relates to a gas distribution assembly comprising a gas cylinder, in particular a medical gas cylinder, a valve block, with or without an integrated expansion system fixed on the gas cylinder, a protective casing arranged around the block. faucet to protect it from shock and dirt and a wireless information transmission system comprising a transmitting and / or receiving antenna. Industrial and medical gases are commonly packaged at high pressure in gas containers, typically gas cylinders with pressures greater than 100 bar absolute, generally between 200 and 350 bar abs or more, equipped with a valve block, with or without built-in expansion valve, ie a simple open / closed type faucet or an integrated pressure reducer valve, also called RDI, to control the flow and pressure of the delivered gas. It is common to arrange around said valve block, a protective cover forming a protective shell around the valve body. Such a cowling is commonly called "hat". Cowlings of this type are described in particular by the documents EP-A-629812, DE-A-10057469, US-A-2004/020793 and EP-A-2586481. The high-pressure gas exiting the container must therefore be expanded before it can be used, that is to say its pressure must be reduced to a lower operating pressure, called low pressure, for example a pressure less than 20 bar abs, or even often less than 10 bar abs. The expansion of the gas can be done either directly in the valve block itself, when it is a built-in pressure regulator valve block, also called RDI, or downstream of the valve block by means of a pressure reducer device. gas. When it is desired to know the pressure of the gas (before expansion) or the residual quantity of gas in the bottle, the valve block is fitted with a device for indicating pressure or gas autonomy which is preferably of electronic nature in a manner to be able to transmit to another device, such as a computer or a remote computer server for example, and / or, conversely, to receive information transmitted by another device. This is generally done by means of a transmitter / receiver system comprising an antenna adapted to and designed to transmit and / or receive information, in particular measurements of pressure or gas autonomy resulting from measurements carried out by the indicator device of pressure or autonomy in gas.
    [0002] 3025587 2 However, it has been found in practice that the congestion constraint does not allow the integration in these transmitter / receiver systems of an antenna of sufficient size to obtain a satisfactory transmission / reception quality. In other words, with the existing devices and the existing cylinder / block 5 valve / cowling assemblies, there are problems of reliability of transmission of information, that is to say of emission or reception, of the limits the size of the antenna of the transmitter / receiver system. The solution of the invention is then a gas distribution assembly comprising: - a gas container equipped with a valve block comprising an internal gas passage, 10 - a protective cowling comprising a cowling body surrounding all or part of said valve block and a carrying handle fixed to said casing body by at least one support post; at least one pressure sensor arranged to measure the gas pressure within said internal gas passage of the valve block; information processing means connected to said at least one pressure sensor, - a wireless information transmission system comprising a transmitting and / or receiving antenna, and - at least one source of electrical energy electrically supplying said processing means and said information transmission system, characterized in that said transmitting and / or receiving antenna is arranged in said at least one support post in holding the carrying handle. In the context of the invention, integrating the antenna to the amount of the carrying handle is advantageous because it allows in particular to: - use an antenna of larger dimensions, therefore to improve emissions and 25 receptions, that is, ie the reliability of information transmission, - protect the antenna against shocks and damage since no antenna exceeds the rollover, and - do not increase the overall size of the assembly. As the case may be, a gas distribution assembly according to the invention may comprise one or more of the following technical characteristics: the wireless information transmission system is capable of and designed to transmit and / or receive any type information, ie, any type of data, alert or order.

The bottle contains gas at a pressure of up to about 350 bar. The invention further relates to a use of a gas distribution assembly according to the invention for storing or dispensing a gas or gas mixture, preferably a gas or medical gas mixture. Preferably, the gas or gas mixture is chosen from oxygen, air, N 2 O 2, He / O 2 or NO / nitrogen. The invention will now be better understood thanks to the following detailed description, given for illustrative purposes but not FIG. 1 represents an embodiment of a cylinder / tap / cowl block assembly according to the invention, FIG. 2 illustrates the architecture of the information processing means and FIG. of the wireless information transmission system 20, and - Figure 3 schematizes the principle of the chain of processing and sending information or data to a remote device. More specifically, it is seen in Figure 1, a protective cover 2, commonly called "hat", arranged around a valve block (not visible), namely a valve with or without integrated regulator, itself fixed on the neck of a gas cylinder 1, preferably the valve block is of type RDI. The lower part, also called the lower part, of the cowling 2 is located at the level of the bottle 1. The fastening around the valve block is on the neck of the gas bottle 1 is done by screwing, either directly on the tap itself. even via a complementary and / or adapted geometry. The gas cylinder 1 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).
    [0003] 3025587 6 The protective cover 2 protects the valve block against impacts. To do this, it comprises a casing body forming a protective shell around an internal volume sized to receive the valve block. The cowling 2 is surmounted by a carrying handle 3 designed to be handled by a user. The carrying handle 3 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is carried by one or more support posts 4 mechanically connecting the casing body to the carrying handle 3. It is preferentially arranged horizontally, that is to say perpendicularly or quasi-perpendicularly to the vertical axis of the bottle 1 and the cowling 2. The carrying handle 3 has an elongated shape, whether straight or curved, typically a length of less than 20 cm, typically 6 to 15 cm. One or more support posts 4 are fixed at one or both ends of the carrying handle 3 so as to allow a user to easily transport the hat / tap / bottle assembly by means of said carrying handle 3.
    [0004] In the embodiment of Figure 1, the handle 3 is carried by two support posts 4 facing each other. These uprights 4 project upwards, substantially vertically, from the upper part of the body of the cowling 2. They have an elongated shape, that is to say that they are elongate. Typically, the height of the uprights 4 is between 5 and 30 cm.
    [0005] In all cases, the casing body 2 is typically made of a polymer and / or metal type material, preferably made of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA. the one or more supports 4 may be formed of a plastic material, such as the body of the cowling 2, but also of aluminum alloy or any other metallic material. They can be attached to the handle 3 by screwing or welding, for example, or formed in one piece. Moreover, the valve body of the valve block conventionally comprises a fastening system, for example a conical, frustoconical or cylindrical threaded portion, for fixing the valve block to the gas container 1, for example by screwing. This threaded portion includes a gas inlet port through which the gas contained in the container 1 can enter the valve body.
    [0006] The valve block further comprises a gas outlet port carried by a gas outlet connector 7 through which the gas can emerge from the valve body. An internal gas passage fluidly connects the gas inlet port to the gas outlet port. A pressure sensor attached to the valve body makes it possible to measure the pressure of the gas in the internal gas passage, preferably upstream of the site where the gas is expanded, when the valve block is of the RDI type and thus integrates a system of pressure. pressure reduction, for example a relief valve cooperating with a valve seat. This sensor makes it possible to determine the pressure of the gas, said pressure being then used by information processing means to possibly deduce a gas autonomy of the bottle 1.
    [0007] Conventionally, a gas flow control member 8, such as a rotary handwheel or pivoting lever, allows the user to control the flow rate of the gas passing through the valve block. This gas flow control member 8 cooperates with a gas passage control system arranged on the internal gas passage, that is to say in the valve block. Here, the gas flow control member 8, namely a rotary flywheel, is located on the front face of the cowling 2 and is arranged around the gas outlet fitting 7 carrying the gas outlet orifice. However, the gas outlet connection 7 could be arranged in another place and is not necessarily coaxial with the flywheel 8. In order to allow the hooking or stowage of the bottle / valve block / cowling assembly to a support Like a hospital bed or stretcher bar, the protective cover 2 may comprise, on the side of its rear face, a fixed or movable attachment device 10, for example translatable or pivoting between a so-called rest ", that is to say the position adopted by the attachment device 10 when stored and in contact or near-contact with the body of the cowling 2 (as shown in Fig. 1), and a position said "hooking", that is to say the position adopted by the hooking device 10 when it is fully extended and can be hooked to a support, such as a bed rail or the like. The protective casing 2 also has a housing arranged at the upper part, also called the upper part, within which housing is housed an information display screen 9 for displaying various information useful to the user. , such as gas pressure or bottle life.
    [0008] For example, the information display device 9 may be designed and able to display information selected from the time, the date, the flow rate of gas delivered by the tap, the pressure of the gas in the bottle 1, autonomy of the bottle 1 gas, the autonomy of the electric source, the ambient temperature, an alarm, the name of the care facility or any other information. In general, the measurements carried out by the pressure sensor 15 are processed, as explained hereinafter, by information processing means 11, 12, for example at least one microprocessor 12 associated with one or more algorithms, and then possibly stored in an information storage memory and / or displayed on the screen 9. An electric source, for example one or more batteries or rechargeable batteries or electric batteries, supplies electric power to the screen 9, as well as the information processing means 11, 12 and the information transmission system 13. The electrical power source 10 is fixed to the valve body or in a housing provided in the wall of the cowling 2. FIG. illustrates a possible architecture of the information processing means and the wireless information transmission system. In general, a main electronic card 11 embeds a calculation module comprising a microprocessor 12, and a communication module 13 which comprises an information processing means capable of transmitting / receiving information, such as an RF module. a GSM modem, a WiFi module, a Bluetooth module or the like, and an antenna 5 electrically connected, via an electrical connection and / or a dedicated connector 16, to the main electronic card 11 carrying the communication module 13.
    [0009] In the embodiment shown in FIG. 2, the information processing means 11, 12 and the information transmission system 5, 13 are carried by one and the same main electronic card 11. However, the communication module forming all or part of the information transmission system 5, 13 could also be or understand or be carried by an additional electronic card connected to the main electronic card 11. According to one embodiment, the additional electronic card is offset in a support post of the handle or in the cowling, while the main electronic card 11 is carried by the valve block. These cards 11 are electrically connected to each other. The information processing means 11, 12 therefore comprise the electronic card 11 which itself comprises the calculator member 12, such as a microprocessor, said electronic card 11 being fixed on the tap or in a housing provided in the wall of the computer. cowling 2, and electrically connected to the pressure sensor 15 fixed to the valve body via an electrical connection and / or a dedicated connector 14.
    [0010] The power supply of the sensor 15 is therefore via the electronic card 11. The information processing means 11, 12 are furthermore connected to the wireless information transmission system 13 comprising the transmitting antenna and / or receiver 5 arranged in the support post 4 carrying the carrying handle 3, so as to be able to transmit information, in particular pressure and / or gas autonomy, to a remote device 20, via the transmitting antenna 5 / receptor. In other words, the wireless information transmission system 13 is adapted to and designed to transmit and / or receive information, i.e., any type of data, alert or order. The transmission of information is to a remote device 20, while conversely, the reception by the information transmission system 13 includes the retrieval of information from a remote device 20. The remote device 20 may be a computer, a computer server, a smart phone, a touch pad .... or any other dedicated device or not. In general, the transmission of information is via the transmitting and / or receiving antenna 5. The antenna 5 is chosen so as to be able to radiate, that is to say emit, and / or pick up, that is to say receive, information in the form of electromagnetic waves, thus capable of performing a conversion in one direction or the other between electrical power and electromagnetic power. FIG. 3 illustrates the principle of the processing chain of the information collected by the sensor 15 and then transmitted via the antenna 5. By way of illustration but without limitation, the following example will be taken of the example of a measured pressure datum. by the sensor 15 in the internal passage of the valve equipping the bottle 1. In this case, the information processing chain schematically comprises the following steps: Step A: Acquisition of one (or more) data (s) by the sensor 15 fixed to the valve, namely here a pressure data. Step B: Processing (ie calculations) of the data by the microprocessor calculator module 12 within the information processing means 11, 12 and formatting of the data or the result of the calculations for a subsequent transmission of this data. 10 - Step C: wireless transmission of the data (or data) by the communication module 13 of the information transmission system 5, 13, via the antenna 5 located in the support post 4 of the handle 3. - Step D: Receipt of or data from a remote device 20, for example a computer, a computer server, a smartphone, a touch pad or the like. This remote device 20 can then display them, memorize them, process them, edit them, use them. Steps A to C are implemented by the gas distribution assembly according to the invention, that is, that is to say are operated at the level of the bottle 1. A gas distribution assembly according to the invention is particularly well suited for storing and / or for distributing a gas or gas mixture, preferably a gas or gas mixture chosen from 02 , air, N20 / 02, He / 02 and NO / nitrogen.
