    专利说明:

    [0001] The invention relates to a gas distribution assembly, including medical gas, comprising a gas cylinder, a valve block attached to the gas cylinder and a protective cowling arranged around said valve block and comprising an electronic display screen allowing the information display, being housed in the upper part of said protective casing. Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without built-in expansion valve, namely a single tap open / closed type or an integrated valve 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. Such a cowling is commonly called "hat".
    [0002] Moreover, to allow the bottle / cap / tap assembly to be hooked to a support, such as a hospital bed bar, a stretcher, a rod or support for attaching an emergency vehicle, for example a SAMU unit or the like, it is customary to arrange on the cap, a fixed attachment system or mobile, including pivoting. In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by users. . 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. It is known to provide the user with information relating to the gas delivered by the bottle (type of gas, pressure, autonomy, etc.). To do this, one can use a gas pressure indicator device, such as a manometer, or gas autonomy that is attached to the valve block or RDI. However, the positioning of this device in the lower part of the valve, due to technical constraints, including the fact that the protective cover surrounds the valve block or RDI, makes it often difficult or not easy to read the indications given by the device, which inevitably leads to read errors that can cause breaks in the gas supply because the user can, in case of misreading, not find that the gas cylinder is empty or almost empty. Moreover, if providing the user with information relating to the gas delivered by the bottle (type of gas, pressure, autonomy) is important, this information is not sufficient and the users have more and more need to dispose of other useful information (date, time, place, name of the hospital ...). However, there is currently no gas distribution assembly equipped with a device for providing a wide variety of information to a user. In view of this, the problem is to propose a gas distribution assembly to provide the user not only information on the gas delivered by the bottle (type of gas, pressure, autonomy) but also, if desired, other useful information (date, time, place, name of the hospital ...), and to make them easily accessible, ie readable by the user, and thus to avoid any or some of the above problems. In addition, the bottle must be able to be used in vertical and horizontal positions, and that the information remains visible and readable whatever the position of use adopted. The solution of the invention is a gas distribution assembly comprising a gas cylinder, a valve block fixed on the gas cylinder and a protective cowling arranged around said valve block, characterized in that the protective cowling comprises a housing arranged at the top of the protective casing and in which housing is housed an electronic display of information. By "electronic display screen" is meant a screen adapted to and designed to display alphanumerically and / or graphically any type of information, that is to say in the form of one or more alphabetic characters. , digital, pictograms, drawings or others.

Preferably, the gas or gas mixture is chosen from oxygen, air, N 2 O 2, He / O 2, NO / nitrogen. The invention will now be better understood thanks to the following detailed description, given for illustrative but not limiting purposes. with reference to the appended figures, in which: FIG. 1 represents a first embodiment of the protective covering of a cylinder / valve block / cowl assembly according to the invention, and FIG. 2 represents a second embodiment of the invention. protection cowl of a bottle / valve block / cowl assembly according to the invention. The figures represent two embodiments of a protective cover 1, commonly called "hat", arranged around a valve block (not visible), namely a valve with or without built-in regulator, itself attached to the neck of a gas cylinder 2, preferably the valve block is of type RDI. The fixing around the valve block on the neck of the gas cylinder 2 is done by screwing. The gas cylinder 2 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] The protective cover 1 protects the valve block against shocks. To do this, it comprises a casing body forming a protective shell around an internal volume sized to receive the valve block.
    [0004] As seen in the figures, it is surmounted by a carrying handle 6 designed to be handled by a user. The carrying handle 6 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 13 mechanically connecting the casing body to the carrying handle 6.
    [0005] It is preferably arranged horizontally, that is to say perpendicularly or almost perpendicular to the vertical axis of the bottle 2 and the cowling 1. The carrying handle 6 has an elongated shape, whether straight or curved, typically a length less than 20 cm, typically 6 to 15 cm. One or more support posts 5 are attached to one or both ends of the carrying handle 6 so as to allow a user to easily transport the hat / tap / bottle assembly by means of said carrying handle 6. In the embodiment of FIG. 2, the handle 6 is carried by two support uprights 5 mechanically connecting the two ends of said handle 6 to the body of the hood 1, whereas in that of FIG. 1, it is carried by a only support member 5 mechanically connecting one end of the handle 6 to the body of the cowling 1, the other end of the handle 6 coming directly to the casing body 1 whose front face 11 is shaped to extend, c that is, projecting itself upwards. In all cases, the casing body 1 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. support posts 5 may be formed of a plastic material, such as the body of the cowling 1, but also of aluminum alloy or any other metallic material. They can be attached to the handle 6 by screwing or welding, for example, or formed in one piece. The protective casing 1 also has an opening or housing 4 arranged at the upper part 1a, also called the upper part, of the front face 11 of the protective casing 1, within which housing 4 is housed a screen 3 electronic display for displaying various useful information to the user. The lower part lb, also called the lower part, of the cowling 1 is located at the level of the bottle 2. The electronic display screen 3 is for example an LCD screen.
    [0006] For example, the screen 3 is designed and able to display information selected from the time, the date, the gas flow delivered by the tap, the gas pressure in the bottle 2, the gas autonomy of the bottle 2, the autonomy of the power source, the ambient temperature, an alarm, the name of the care facility or other. In order to be able to display all or part of this information, provision is also made for one or more sensors, such as one or more sensors for pressure, flow, position of the control member (lever or flywheel), presence of the user or other. The measurements performed by this or these sensors are processed by information processing means, for example a microprocessor associated with one or more algorithms, then optionally stored in an information storage memory, and finally transmitted via a suitable connector, the electronic screen 3 on which they can be displayed. An electrical source, for example one or more batteries or electric batteries, supplies electrical power to the screen 3, as well as the sensor or sensors, and the information processing means, in particular the microprocessor, and possibly the storage memory. information.
    [0007] The information processing means and the electrical source are arranged in one (or more) internal housing arranged in the cowling 1. As illustrated in FIGS. 1 and 2, a flat surface 9 is arranged at the front face 11 of FIG. the upper part 1a of the protective casing 1, in which flat surface 9 is arranged the housing 4 receiving the electronic display screen 3.
    [0008] In the embodiment of Figure 1, the housing 4 is arranged in the front face portion 11 shaped to extend, that is to say, projecting upwards and acting as support post for the carrying handle 6. Preferably, the axis BB of the screen 3 is oblique with respect to the axis AA of the cowling 1 and the bottle 2, that is to say that said axes AA and BB form between they an angle a less than 70 °, preferably less than 60 °, as shown schematically in Figure 1. According to the embodiment considered, the screen 3 is arranged in the housing 4 arranged in the flat surface 9 so that its upper window is flush with said flat surface 9, or is slightly recessed within the housing 4 or, conversely, slightly protruding outwards with respect to the flat surface 9.
    [0009] Such an arrangement of the screen 3 in the upper position 1a and the front 11 of the cowling 1, with its reading glass inclined to form an angle has given (<70 °) relative to the axis AA of the cowling 1 and of the bottle 2, makes it considerably easier for the user to read the information delivered by the electronic display screen 3 and to avoid reading errors. Furthermore, the protective casing 1 comprises a gas flow control member, such as a rotary wheel 7 (Figure 2) or a movable cursor (Figure 1), controlling the flow of gas passing through the valve block. In the embodiment of Figure 2, which is preferred, the rotary wheel 7 is located on the front and is arranged around a gas outlet connection 8 for withdrawing the gas delivered by the valve. However, the gas outlet connection 8 could be arranged at another location and is not necessarily coaxial with the steering wheel 7.
    [0010] In order to allow the hooking or securing of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective casing 1 may comprise, on the side of its rear face , a pivoting attachment device 10 between a fully folded position, called "rest", that is to say the position adopted by the attachment device 10 when stored and in contact or near-contact the body of the cowling 1 (as illustrated in FIG 2), and a fully unfolded position called "hooking", that is to say the position adopted by the attachment device 10 when fully extended and can be hooked to a support, such as a bed rail or the like. A gas cylinder 2 equipped with a cowling 1 according to the invention is particularly suitable for use in a medical environment, in particular it is suitable for the storage of any gas or medical gas mixture, in particular of the oxygen, air, N 2 O 2 type. , He / 02, NO / nitrogen or other.
