Internal telescopic guide for an inflatable air cushion
First Claim
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, anda telescopic guide inside the interior space, and coupled to, the cushion,wherein the telescopic guide expands and contracts in a direction perpendicular to the base plate when the interior space is pressurized.

Abstract
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), the first end of which is attached to the base plate (5) and the second end of which is attached to 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).
