Patent

CA 2668055

A portable life support apparatus (1102) and particularly a respiratory support apparatus adapted to be easily mounted to a stretcher is disclosed. Prior devices that attach onto a stretcher are heavy and cumbersome and obstruct access to the patient. Accordingly, there is a great need for a portable emergency support device that overcomes the weight, size, positioning, and other portability disadvantages. One aspect relates to a portable life support device including at least one ambient gas inlet (14); a conditioned gas outlet (30); an oxygen concentrator (26,28) fluidly connected between the at least one gas inlet and the gas outlet, and a ventilator (44) fluidly connected downstream from the oxygen concentrator. A further aspect is directed to a portable life support apparatus in the form of a portable respiratory support apparatus (1102) capable of exploiting both ambient air and expired gas as oxygen sources, wherein the oxygen generator (20) and ventilator (10) are arranged end to end to provide a longitudinal profile that can thus be compactly secured to a stretcher or other similar emergency transport vehicle.

L'invention concerne un dispositif de survie portable (1102) et, en particulier, un dispositif d'aide respiratoire conçu pour être monté sans difficultés sur une civière. Les dispositifs de l'état actuel de la technique, qui se fixent à une civière, sont lourds et encombrants et gênent l'accès au malade. De ce fait, il existe un besoin important de dispositif portable d'urgence exempt des inconvénients posés par le poids, les dimensions, le positionnement ou la difficulté de manipulation. Un aspect concerne un dispositif de survie portable comprenant au moins une entrée (14) de gaz ambiant; une sortie (30) de gaz traité; un concentrateur d'oxygène (26, 28) reliant de façon fluide l'entrée et la sortie de gaz; un ventilateur (44) branché de façon fluide en aval du concentrateur d'oxygène. Un autre aspect concerne un dispositif de survie portable se présentant sous la forme d'un dispositif portable (1102) d'aide respiratoire, capable d'exploiter à la fois l'air ambiant et le gaz expiré en tant que sources d'oxygène, le générateur d'oxygène (20) et le ventilateur (10) étant placés bout-à-bout afin de constituer un profilé longitudinal pouvant être fixé compact à une civière ou autre véhicule analogue de transport d'urgence.
