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 ).
