Definitions

  • This invention relates to a monitoring device and is concerned with a monitoring device for use with breathing apparatus as worn by firefighters and the like.
  • the device may also include a means of actuating the alarm means to produce a signal to prompt the firefighter or the like to read the display in the event that the pressure detected by the pressure sensor falls below a predetermined value (which constitutes a first warning level) and/or, as appropriate, if the temperature detected by the temperature sensor exceeds a predetermined value.
  • a predetermined value which constitutes a first warning level
  • the main unit comprises a housing 1 including an automatic distress unit (ADSU) comprising an alarm means in the form of a piezo sounder and a movement sensor (not shown).
  • the housing also includes an LCD display 2 positioned behind a protective window.
  • the housing 1 is linked to another unit of the device comprising a pressure sensor (not shown) by means of a hose 3.
  • the pressure sensor output is digital and holds its own calibration data in an electrical erasable programmable read only memory.
  • the pressure sensor operates over a pressure range of from 0 to 300 bars and is connected to a container (not shown) for gas to be breathed by the user.
  • the circuitry within the main unit additionally includes an ambient temperature sensor and the detected temperature is also displayed on the display 2, as an alternative to the calculated time to the whistle, by pressing button 4.
  • This circuitry may include a two stage pre-set (software adjustable) warning of increasing heat intensity and may also monitor the time for which the user has been subjected to a wide range of heat levels and trigger accumulated heat warnings.
  • a piezoelectric sounder 83 is glued into the housing 1 by an epoxy ring 85.
  • the epoxy ring provides a gas-tight seal of the sounder to the housing.

Claims (13)

  1. Dispositif de surveillance adapté pour être raccordé de façon fonctionnelle à un appareil respiratoire comprenant une enceinte contenant un gaz respiratoire sous pression, le dispositif de surveillance et l'appareil respiratoire étant portés tous les deux par un utilisateur, ledit dispositif comprenant :
    un capteur de pression (51) adapté pour détecter la pression du gaz dans l'enceinte ;
    un détecteur de mouvements (57) adapté pour détecter les mouvements de l'utilisateur ; et
    des moyens d'avertissement (63) connectés à la fois au capteur de pression (51) et au détecteur de mouvements (57), et adaptés pour produire un signal d'un premier type lorsque la pression dans l'enceinte est plus basse qu'une valeur prédéterminée et un signal d'un deuxième type lorsque aucun mouvement de l'utilisateur n'est détecté au terme d'une période de temps prédéterminée, caractérisé en ce que le dispositif comprend en outre des moyens de détection de fuites adaptés pour détecter une fuite de gaz à partir de l'enceinte, lesdits moyens de détection de fuites étant configurés, à l'utilisation, pour pouvoir comparer la pression mesurée par le capteur de pression à des intervalles de temps réguliers.
  2. Dispositif de surveillance selon la revendication 1 dans lequel lesdits moyens d'avertissement (63) sont adaptés pour produire une série de signaux du premier type lorsque la pression dans l'enceinte baisse durant l'utilisation, chaque signal étant produit après qu'une baisse de pression prédéterminée a été enregistrée depuis que le dernier signal précédent de la série a été reçu.
  3. Dispositif de surveillance selon la revendication 2, dans lequel, lorsque la pression dans l'enceinte baisse à un niveau prédéterminé, le capteur de pression (51) amène les moyens d'avertissement à produire un signal pour indiquer à l'utilisateur qu'il doit évacuer l'endroit et se mettre à l'abri.
  4. Dispositif de surveillance selon l'une quelconque des revendications précédentes, dans lequel les signaux du premier et du deuxième types sont des signaux audibles ayant des fréquences différentes.
  5. Dispositif de surveillance selon l'une quelconque des revendications précédentes dans lequel le capteur de pression (51) est connecté de façon fonctionnelle à un écran d'affichage (59) qui fournit une indication visible de la pression du gaz dans l'enceinte.
  6. Dispositif de surveillance selon la revendication 5, comprenant en outre des moyens permettant d'activer les moyens d'avertissement (63) afin de demander à l'utilisateur de lire l'écran d'affichage (59) dans le cas où la pression détectée par le capteur de pression baisse plus bas qu'un niveau d'alerte prédéterminé.
  7. Dispositif de surveillance selon l'une quelconque des revendications précédentes, comprenant en outre des moyens (61, 64) permettant d'activer manuellement les moyens d'avertissement de sorte qu'ils produisent un signal du deuxième type.
  8. Dispositif de surveillance selon l'une quelconque des revendications précédentes comprenant en outre une sonde de température et un écran d'affichage (59) adapté pour afficher la température.
  9. Dispositif de surveillance selon la revendication 8 muni de moyens permettant d'activer les moyens d'avertissement, afin de demander à l'utilisateur de raccorder l'écran d'affichage, lorsque la température mesurée par la sonde de température dépasse une certaine valeur prédéterminée.
  10. Dispositif de surveillance selon la revendication 1 comprenant un récepteur (55) adapté pour recevoir de nouvelles valeurs relatives à ladite valeur de pression prédéterminée et à ladite durée prédéterminée, et des moyens de stockage adaptés pour stocker les nouvelles valeurs.
  11. Dispositif de surveillance selon la revendication 10 comprenant en outre un émetteur, moyennant quoi une valeur mesurée par un détecteur peut être transmise à un endroit extérieur.
  12. Dispositif de surveillance selon la revendication 11 dans lequel le récepteur (55) est un récepteur à infrarouges et l'émetteur est un émetteur à infrarouges.
  13. Dispositif de surveillance selon l'une quelconque des revendications précédentes comprenant :
    un premier module (71) comprenant le capteur de pression ; et
    un deuxième module (51, 52) comprenant les moyens d'avertissement (63), le détecteur de mouvements (57), ainsi que l'ensemble des fonctions d'interface nécessaires et des circuits associés ;
    les deux modules étant connectés ensemble de façon fonctionnelle.
