Definitions

  • the invention relates to a pressurized fluid container, in particular a pressurized gas cylinder, equipped with a fluid dispensing tap comprising an electronic device with detection of a malfunction of the temperature sensor, and its use for storing or dispensing a pressurized gas, in particular a medical gas chosen from oxygen or a gas mixture N 2 O/O 2 , NO/N 2 , He/O 2 , Ar/O 2 or medical air, i.e. of medical quality.

  • 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 cylinders or canisters, which are equipped with a distribution tap, with (RDI) or without an integrated pressure reduction system, used to supply the medical gas and a needle pressure gauge or an electronic device with a digital display used to display the residual gas pressure or gas autonomy.
  • gas cylinders or canisters which are equipped with a distribution tap, with (RDI) or without an integrated pressure reduction system, used to supply the medical gas and a needle pressure gauge or an electronic device with a digital display used to display the residual gas pressure or gas autonomy.
  • RDI distribution tap
  • EP-A-2918893 offers a gas bottle equipped with an RDI and a needle pressure gauge
  • EP-A-2918892 offers a gas cylinder equipped with an RDI and an electronic device with a digital display screen.
  • a rigid protective cover also called a "hat" is
  • the electronic device includes in particular (micro)processor control means and a display screen, cooperating with pressure and temperature sensors, in order to be able to measure the pressure and temperature of the gas, then to calculate and display useful information, such as the volume of gas or the gas pressure in the container and/or gas autonomy depending on the gas flow rate delivered by the distribution tap.
  • useful information such as the volume of gas or the gas pressure in the container and/or gas autonomy depending on the gas flow rate delivered by the distribution tap.
  • Pressure and temperature sensors are usually integrated into the electronic device. They are connected to the gas circuit carrying the gas under pressure in the body of the distribution tap, via a tapping, i.e. a small channel allowing the pressurized gas to be brought to the measuring elements of these sensors, as illustrated by EP-A-3421866 .
  • a temperature sensor can be used that can measure only the gas temperature as described by EP-A-3067665 , or a combined pressure and temperature sensor capable of measuring both temperature and pressure, as described by FR-A-3112192 Or FR-A-3133425 .
  • the temperature sensor whether it is a combined temperature and pressure sensor or a temperature-only sensor, malfunctions and provides erroneous or aberrant temperature measurements to the control means, which then use these erroneous measurements to calculate, in particular, a gas autonomy which is then necessarily erroneous.
  • a problem is therefore to be able to quickly detect a malfunction of the temperature sensor in order to avoid calculation and display of erroneous data by the electronic device, in particular gas autonomy, and then to alert the user of this malfunction of the temperature sensor.
  • the data processing means are configured to trigger an audible or visual alert in response to a detection of malfunction of said first temperature sensor when said detection of malfunction of said first temperature sensor is repeated over a given duration (T) of several tens of minutes and/or for at least 5 successive temperature measurements (T m , Tf).
  • the invention relates to a use of a container according to the invention for storing or supplying a gas under pressure, in particular a medical gas chosen from oxygen, a gas mixture N 2 O/O 2 , NO/N 2 , He/O 2 , Ar/O 2 or medical air.

  • Fig. 1 is a schematic diagram of a pressurized fluid container 1 according to the invention, whereas the Fig. 2 represents an embodiment of such a fluid container 1, namely here a pressurized gas bottle of axis AA.
  • the fluid container 1 comprises an internal volume 2 for storing fluid, namely here a pressurized gas, for example at more than 200 bar abs (full pressure), and is equipped with a fluid distribution tap 3, such as an RDI or integrated pressure reducing valve, crossed by an internal fluid passage or circuit in fluid communication with the internal volume 2 of the container 1 so as to convey the fluid, namely here gas, within the body of the gas distribution tap 3 to a flow outlet connection 11 to which is connected fluidly for example a flexible gas line (not shown) or other device using the delivered gas.
  • a fluid distribution tap 3 such as an RDI or integrated pressure reducing valve
  • the AA axis gas bottle or container 1 of Fig. 2 comprises a cylindrical body and a neck, i.e. it is ogive-shaped.
  • the cylindrical body defines the internal volume 2 for storing gas under high pressure, typically a maximum pressure of 130 to 300 bar abs, or even beyond 300 bar abs.
  • the neck comprises a fluid inlet/outlet orifice communicating with the internal volume 2 and allowing gas to be withdrawn from the internal volume 2 or, conversely, to be filled when it is empty.
  • the gas distribution valve 3 is mounted, typically screwed, at the orifice of the neck of the gas cylinder.
  • the container 1 has a generally cylindrical shape, in particular a bullet-shaped shape, made of metal or metal alloy (e.g. steel, aluminium, etc.) or of composite material(s). It contains a gas or gas mixture, such as oxygen, a NO/N 2 , O 2 /N 2 O, Ar/O 2 or He/O 2 mixture, air or other.

  • the gas distribution tap 3 namely here an RDI including internal expansion means, is aimed at the neck of the gas cylinder. It comprises a gas distribution connector or nozzle, called flow outlet connector 11, to which can be connected for example a flexible gas line, such as a flexible plastic pipe, used to convey the gas to a medical apparatus or device using the gas supplied by the tap 3, for example a breathing mask distributing gas to a patient at a flow rate prescribed by a doctor or the like corresponding to a treatment to be followed.
  • a gas line such as a flexible plastic pipe
  • the faucet body is preferably made of brass or stainless steel.
  • the gas distribution valve 3 here comprises a first sensor 4, which is here a combined temperature and pressure sensor, for measuring not only the temperature of the fluid (Tf), i.e. here of the gas, but also the pressure of the fluid, within the internal fluid passage and/or in the internal volume 2 of the container 1, and providing temperature and pressure measurements (i.e. measurement values or signals) to data processing means 5 with a microprocessor 15, i.e. a control device or a data processing unit comprising one or more microprocessors 15 implementing one or more algorithms, for example an electronic card carrying one (or more) microprocessors 15 implementing one or more calculation algorithms or others, preferably a microcontroller.
