Definitions

  • the invention relates to a pressurized fluid container, in particular a pressurized gas cylinder, equipped with a fluid distribution valve equipped with an electronic device and a dissociated pressure (and temperature) sensor, c that is to say independent of the electronic device, making it possible to carry out pressure (and temperature) measurements and to supply them to the electronic device, via electrical connection means, such as a layer with several electrical cables.
  • Medical fluids or gases such as oxygen, NO/N 2 , N 2 O/O 2 , He/O 2 , medical air or other mixtures, are packaged in pressurized gas containers, in particular gas cylinders or cylinders, which are equipped with a dispensing valve, also called a valve, with an integrated expansion system (RDI) or without an integrated expansion system, used to provide an adjustable gas flow.
  • a dispensing valve also called a valve
  • RTI integrated expansion system
  • a rigid protective covering also called a “hat”, serves to protect the tap and its fragile equipment against shocks, falls, dirt, etc.
  • the tap or distribution valve can be equipped with an electronic device with a digital display used to display the residual gas pressure in the container or a gas autonomy, that is to say the duration of use before that the container is (almost) empty, as taught by EP-A-2918892 , EP-A-3421866 , US-A-2015/048955 , US-A-6085598 , EP-A-3067665 Or DE-A-3809142
  • Such an electronic device generally comprises a box embedding one or more (micro)processors carried by a main electronic card and a display screen making it possible to calculate and/or display one or more parameters useful for the user, such as gas flow, gas pressure, autonomy, gas volume or any other parameter.
  • Pressure measuring means are also provided, in particular a pressure sensor or combined pressure and temperature fitted into the housing, that is to say fixed to each other, which are connected to the card.
  • electronic in particular to the (micro)processor to transmit the pressure measurements which are processed there electronically by one or more microprocessors.
