Definitions

  • the invention relates to a pressurized gas container, in particular a pressurized gas cylinder, equipped with a gas distribution valve, typically gas, with at least two gas outlets and further comprising an electronic device configured to allow calculation and display of gas autonomy, as well as a graphical representation of a medical ventilator indicating to the user that a medical ventilator uses gas coming from one of the outlets of the gas distribution valve.
  • Medical fluids or gases such as oxygen, NO/N 2 , N 2 O/O 2 , He/O 2 mixtures, medical air or other, are generally packaged in pressurized gas containers, in particular gas bottles or canisters, which are equipped with a distribution tap, also called a “cock block” or “valve”, with (RDI) or without an integrated expansion system, used to supply medical gas and a pressure gauge needle or an electronic device with a digital display used to display the residual gas pressure or gas autonomy.
  • a distribution tap also called a “cock block” or “valve” or without an integrated expansion system
  • EP-A-2918892 offer a gas cylinder equipped with an RDI and an electronic device with a digital display screen, ie digital.
  • a rigid protective covering also called a “hat”, is used to protect the tap and its equipment against shocks, falls, dirt, etc.
