Internal telescopic guide for an inflatable air cushion
View Patent ↗The invention provides an air cushion unit ( 4 ) for use in conjunction with a compression device for stopping bleeding from puncture wounds. The air cushion unit ( 4 ) comprises a base plate ( 5 ), an inflatable air cushion ( 6 ), which is attached to the base plate ( 5 ), and an internal telescopic guide ( 7 ), connecting the base plate ( 5 ) with the top of the air cushion ( 6 ). Throughout the pressurizing of the inflatable air cushion ( 6 ), the length of the telescopic guide ( 7 ) corresponds to the degree of expansion of the air cushion ( 6 ), thereby providing an internal support for the air cushion unit ( 4 ), which eliminates undesired, irregular movements of the air cushion ( 6 ).
1. An inflatable cushion assembly to apply pressure to a patient, comprising:
a base plate,
an inflatable cushion adapted to apply pressure to a wound, the inflatable cushion defining an enclosed interior space which is configured to be pressurized,
two extensions connected to the base plate,
at least one belt fastener, connected to at least one of the extensions, for receiving a belt to hold the inflatable cushion against the patient, and
a telescopic guide at least partly inside the interior space, and coupled to, the cushion,
wherein the telescopic guide expands in a direction perpendicular to the base plate when the interior space is pressurized,
wherein an end of the telescopic guide is attached to the inflatable cushion at a portion away from a top portion of the inflatable cushion.
2. An inflatable cushion assembly as set forth in claim 1 , wherein the end of the telescopic guide is attached to the inflatable cushion via a ring-shaped member.
3. An inflatable cushion assembly as set forth in claim 1 , wherein the telescopic guide extends a distance away from the base plate on a side of the base plate that is opposite to the inflatable cushion.
4. An inflatable cushion assembly as set forth in claim 1 , further comprising a device to releasably attach the base plate to the two extensions.
