摘要:
L'invention concerne une cartouche de stockage d'oxygène portative comprenant un corps de cartouche (13) avec un volume interne (12) servant au stockage de l'oxygène contenant au moins un lit d'adsorbant (14) contenant au moins un premier adsorbant (14-1) présentant une capacité d'adsorption pour le dioxyde de carbone gazeux supérieure à une capacité d'adsorption pour l'oxygène gazeux. Est prévu en outre une ligne de bipasse (71) permettant de dévier une partie du gaz entrant dans le volume interne (12). La ligne de bipasse (71) est formée d'un matériau transparent et contient au moins un second matériau adsorbant (75) et au moins un matériau indicateur de saturation de manière à permettre de visualiser une saturation du second matériau adsorbant (75) par le dioxyde de carbone présent dans le gaz circulant dans la ligne de bipasse (71). Ensemble de distribution d'oxygène de secours incluant une telle cartouche (1) reliée à une interface respiratoire (25) et à un réservoir de gaz (5).
摘要:
Provided is a portable air purifier, which includes: a mask part; a first connecting hose having one end connected to the mask part; a second connection hose in which the first connection hose is installed, and at least part of which has an opening for introducing external air; an air purification module that purifies the introduced external air to a predetermined temperature condition and discharges the purified air to the first connecting hose; and a power supply unit configured to supply power to the heater. Since the air purification module for removing poisonous gases or biochemical pollutants through a catalytic reaction of a metal catalyst layer can be semi-permanently used, the conventional inconvenience of carrying an extra canister is removed.

The invention relates to a hygiene filter for a device for artificial respiration, having at least one filter for filtering microorganisms and/or solid particles from a respiratory air volume flow, and to a device for artificial respiration, having a holding device within the air intake region. The filter material is designed as a sealing means against the respiratory air volume flow conducting elements such that the risk of the occurrence of secondary air is reduced.
