Definitions

  • the invention relates to a small medical gas cylinder with tap or gas expansion valve, the whole being protected by a rigid protective shell, which can also be covered with a heat-shrinkable film ensuring hygiene compatible with the concept of medicine.
  • pressurized gas cylinders are provided with or without an integrated system for operating the gas.
  • the mechanical protection of the bottle and possibly of its integrated system of implementation of the gas can be provided by a cap or protective cover to protect the upper part of the bottle, that is to say the tap or tap-regulator for releasing the gas and the various elements associated therewith, such as one or more manometers or the like.
  • thermoformed films improves the cleanliness and the hygiene of the bottle, it does not give a maximum guarantee because it never protects the entirety of the bottle and its system of implementation of the gas.
  • some disposable devices are designed to fit the shape of the bottle and its gas implementation system. They are changed at each filling of the bottle but, in general, they imperfectly marry the complex contours of the bottle and its device for implementing the gas or these disposable devices are only suitable for large gas cylinders weighing several ten kilograms and having a size greater than 60 cm, therefore incompatible with use on small bottles, that is to say less than 50 cm in height.
  • EP-A-903162 proposes to protect a reserve of breathing air with an outer cover formed of two sub-watertight parts with connecting pipe to the outside.
  • EP-A-903162 proposes to protect a reserve of breathing air with an outer cover formed of two sub-watertight parts with connecting pipe to the outside.
  • such equipment is not suitable for medical use, in particular for the reasons already mentioned above, since it simply constitutes a reserve of emergency air that can be used in an emergency, for example by the pilot of an aircraft in case crash at sea or similar.
  • the present invention aims to solve these problems by improving existing equipment by providing equipment to effectively protect the medical gas cylinders and valves, pressure regulators, manometers and / or other elements equipping them against shocks and other damage, especially in the event of a fall on the floor, which also ensures better hygiene and more efficient cleaning of the gas cylinder, while offering better ergonomics, low weight and easier grip for the user. and making the product more aesthetic, therefore more compatible with a use of the treatment in public and / or ambulatory, that is to say outside hospital, since the equipment of the invention should be able to be used almost continued by the patients.
  • the protective equipment of the bottle must be easily placed around the bottle to protect or, conversely, removed during maintenance operations, while allowing easy connection of the outlet of the tap or gas expansion valve equipping the medical gas cylinder to a gas distribution equipment, such as a valve on demand.
  • the solution of the invention is then a portable gas distribution equipment comprising a gas cylinder having a height less than 50 cm, a valve or gas expansion valve mounted on the bottle, and mechanical protection means arranged around the bottle and said valve or gas expansion valve, said protection means comprising at least one outer rigid shell formed of at least two sub-parts comprising hooking means for securing said subparts jointly, one to the other.
  • the sub-parts comprise two half-shells joined to one another forming a protective shell covering the entire body of the bottle and at least a portion of the tap or pressure-reducing valve, a cap shutter is attached to the two half-shells next to the tap or expansion valve, at least one of said protective half-shells and / or the closure cap comprises an access located opposite the valve or pressure-reducing valve so as to allow access to at least one connection of said valve or pressure reducer, and the weight of the assembly is less than 5 kg.
  • the invention therefore proposes, as diagrammatically shown in the attached figures, to careen the assembly formed by the bottle 1 of gas under pressure, in particular a medical oxygen bottle or a mixture of oxygen and oxygen.
  • helium and its system 2 of implementation of the gas, that is to say mainly the valve or valve-regulator mounted on this bottle, by a rigid shell 3, 3a, 3b protective plastic, which nevertheless allows to the user has easy access to the organs and elements of use, including one (or more) gas outlet connection carried by the tap or pressure reducer 2, and which also guarantees inviolability before its first implementation implemented by said user.
  • One of the advantages of the whole of the invention is that the risk for the user is low because there is no direct contact between the user and the high pressure part since it is located under the protective shell, the only contact zone being the demand valve output 4 which is at low pressure.

More specifically, the guarantee of inviolability is obtained thanks to to a tamper-proof cover 13 mounted on the cap 5 and which must be removed by the user before the first use of the gas. This also makes it possible to distinguish a full bottle not used, and therefore with lid 13, a bottle already used, that is to say without operculum.
  • the external profile obtained after fixing the two half-shells 3a, 3b, one with the other allows an optimized manual grip of the equipment at a constriction 12 formed in the half-shells 3a, 3b about the upper third of said half-shells.
  • this constriction 12 is dimensioned so that it allows manual gripping of the equipment at this constriction 12, that is to say it is sized to allow a patient to take a hand of the equipment.
  • this constriction 12 confers a new aesthetic to the equipment of the invention particularly suitable for use in the field of health and more particularly for use by patients treated at home.
