Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
202 words
An oxygen compressive chamber for rendering emergency medical aid to the patient placed inside said chamber, comprising first and second rigid end-face walls; a collapsible elastic side wall connected with the first of said end walls; a stretcher formed by a bed with tubular rods connected to the second of said end walls on one end; tubular sockets mounted in said first end wall and connected to the free ends of said rods of the bed so that when the said side wall is connected with said second end wall said side wall jointly with said end walls forms a closed volume wherein the bed is arranged; an airtightening connector releasably connecting said side wall to said second end wall; and means for supplying the chamber mounted on said first end wall with an oxygen supply means arranged in the leg portion, said system having circulation and purging injectors with outlets of each terminating within the corresponding one of said sockets in the first end wall, perforated manifold means disposed on said second end wall and communicating with said tubular stretcher rods, Whereby said stretcher installed in said sockets conducts oxygen into the head portion of the chamber through said perforated manifold.
Claim 2
Dependent Claim

An oxygen compressive chamber for rendering emergency medical aid to the patient placed inside said chamber, comprising first and second rigid end-face walls; a collapsible elastic side wall connected with the first of said end walls; a stretcher formed by a bed with tubular rods connected to the second of said end walls on one end; tubular sockets mounted in said first end wall and connected to the free ends of said rods of the bed so that when the said side wall is connected with said second end wall said side wall jointly with said end walls forms a closed volume wherein the bed is arranged; an airtightening connector releasably connecting said side wall to said second end wall; and means for supplying the chamber mounted on said first end wall with an oxygen supply means arranged in the leg portion, said system having circulation and purging injectors with outlets of each terminating within the corresponding one of said sockets in the first end wall, perforated manifold means disposed on said second end wall and communicating with said tubular stretcher rods, Whereby said stretcher installed in said sockets conducts oxygen into the head portion of the chamber through said perforated manifold.
Claim 3
Dependent Claim
132 words
An oxygen compressive chamber as defined in claim 1, including means for remotely injecting medicine into said patient; air conditioning means for conditioning the air to a desired temperature and humidity within said chamber; control panel means with intercom means, said chamber being collapsible for storage and transportation, said chamber being free of an external electrical source of power, said oxygen supplying means comprising compressed gas flasks for building up pressure inside said chamber, said chamber being substantially cylindrical for building up pressure within said chamber; a manually controlled safety valve communicating with said chamber for exhausting the oxygen supplied by said flasks from said chamber; and injectors communicating with said chamber for supplying said oxygen to said chamber and intermixing the gas inside the chamber for preventing development of stagnation zones.
Claim 4
Dependent Claim
93 words
An oxygen compressive chamber as claimed in claim 2, wherein the said airtight connector comprises two profiled flanges, one of said flanges being disposed on the second end wall of the chamber, while the other is secured to the side wall of the chamber, the former of said flanges incorporating an inflatable rubber bead and a metal L-shaped split ring carrying on the joint thereof a two-link lever lock, while the latter of said flanges is fitted with an airtightening seat and a shoulder, the latter shoulder cooperating with said L-shaped split ring.
