Definitions

  • the invention relates to a gas container, such as a gas cylinder, for storing or distributing gas, which is equipped with a gas distribution valve for delivering the gas at various user-selectable rates, and to which is mounted an electronic device for measuring gas autonomy comprising a display, such as a digital screen, to display gas autonomy values calculated with respect to corresponding selectable flow values.
  • a gas container such as a gas cylinder
  • gas distribution valve for delivering the gas at various user-selectable rates
  • an electronic device for measuring gas autonomy comprising a display, such as a digital screen, to display gas autonomy values calculated with respect to corresponding selectable flow values.
  • Such a gas container is generally equipped with a gas distribution valve usually comprising flow selection means to allow a user to choose a desired gas flow rate and a gas outlet fitting or outlet to deliver the gas to the gas. desired gas flow rate having been selected.
  • the gas distribution valve is protected by a cover or protective cap forming a protective shell against impacts, dirt, etc.
  • gas containers are for example described by EP-A-3006810 , EP-A-2940370 , EP-A-2937620 and EP-A-29.
  • a practical problem for users of gas cylinders or the like is that they often have to choose between several cylinders stored, for example in a depot or an intervention vehicle, depending on the patient to be treated and the prescription they need. give this patient, that is to say the gas flow rate (eg expressed in L / min) that they must administer to him for a determined duration. For example, a patient may need 2 L / min of oxygen for a period of 1 hour.
  • the choice of a gas cylinder to be used for treating a given patient should be made by the user so that the cylinder chosen can be used throughout the entire period. desired treatment duration and at the selected rate, that is to say so as to comply with the prescription made to the patient to be treated.
