Many of the configurations in this schematic diagram are the same as the schematic diagram (FIG. 2) of the piping that also serves as a block diagram of the medical oxygen supply apparatus 1 of the first embodiment described above, and thus the common configurations are the same. The description will be omitted as the reference numerals and the like, and the following description will focus on the differences.
  • the central controller 200 causes the operation of the compressor 10 and immediately closes the demand valve 117 to stop the supply of concentrated oxygen and to send an electrical signal for voice guidance. I am trying to send it.
  • the central control unit 200 sends an electric signal for stopping the operation of the compressor 10 to the motor control unit 201 and the flow control unit 202 closes the demand valve 117 by the electric signal informing the presence / absence of the flame.
  • An electric signal for stopping the supply of the gas is sent to the releasing means of the coupler 13 for releasing the connection between the coupler 13 and the oxygen outlet 7.
  • the release means of the coupler 13 only has to automatically release the connection between the oxygen outlet 7 and the coupler 13 under the control of the central control unit 200.
  • the elastic means of an elastic body such as a compression spring is used. Any means such as automatic release or solenoid type automatic release using repulsion due to electromagnetic force may be used.
  • An embodiment of the releasing means for the coupler 13 of the present invention will be described later.
  • a flame detection method of the ultraviolet sensor 4221 for example, a flame burned with hydrogen emits light having a strong ultraviolet wavelength in the range of 185 to 260 nm. Thus, the presence or absence of a flame is determined.
  • the ultraviolet sensor 4221 detects a medical oxygen supply device 4001 and / or a flame around the device, stops the operation of the compressor 10 and the supply of concentrated oxygen, and the connection between the oxygen outlet 7 and the coupler 13 is performed. It is a flowchart of operation
  • the medical oxygen supply device 4001 is activated, the process proceeds to step S310, and the presence / absence of flame of the ultraviolet sensor 4221 is determined.
  • the ultraviolet sensor 4221 can detect the flame by continuously determining the presence or absence of a flame around the apparatus and / or the apparatus, for example, every 5 minutes in consideration of power consumption, and in step S311, the flame is detected.
  • step S312 the central control unit 200 that has detected the presence of flame from the ultraviolet sensor 4221 causes the motor control unit 201 to stop the operation of the compressor 10 and causes the flow rate control unit 202 to stop the supply of concentrated oxygen. Then, the connection between the oxygen outlet 7 and the coupler 13 is automatically released (step S312). Thereafter, voice guidance is performed in step S313, and the process is terminated. On the other hand, when no flame is detected in step S311, the process returns to step S310 and is repeated from step S310. In steps S312 and S313, if the operation of the compressor 10 and the supply of concentrated oxygen are stopped, the connection between the oxygen outlet 7 and the coupler 13 is automatically released, and voice guidance is executed, the objective is achieved.
  • step S313 may be reversed or may be executed simultaneously. Furthermore, by disposing a closing valve (not shown) at the oxygen outlet 7, the oxygen outlet 7 can be closed as soon as an abnormal temperature rise is detected, and the oxygen supply can be stopped (step S 312 or step S 313).
  • a closing valve not shown
  • the voice guide has the same configuration as that of the first embodiment described above.
  • the patient always has an additional freshly charged external battery, so that the patient can go out for a longer time and the QOL at that time is greatly improved.

Abstract

L'invention porte sur une thérapie d'inhalation d'oxygène utilisant un dispositif classique à domicile qui peut être susceptible d'un incendie au niveau de l'orifice d'inhalation d'oxygène d'une canule nasale ou d'un masque buccal par le fait de fumer ou subir une inflammation du fait de l'utilisation du dispositif au voisinage d'un feu tel qu'une poêle, provoquant ainsi un incendie. L'invention porte sur un dispositif clinique d'alimentation en oxygène comprenant un moyen d'acquisition d'oxygène très dense, un moyen d'alarme destiné à signaler à la voix un accident lorsque celui-ci se produit, et un moyen de commande destiné à commander ces deux moyens. Le dispositif clinique d'alimentation en oxygène comprend en outre un détecteur de température dans une position appropriée du corps de celui-ci, de telle sorte que le dispositif interrompt l'alimentation de l'oxygène très dense et exécute un guidage vocal lorsque la température détectée par le détecteur de température atteint ou dépasse une valeur prédéterminée.
