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).

Claims

1. An inflatable cushion unit to close a wound in a patient, comprising:

an inflatable cushion adapted to close a wound in a patient; and

a telescopic guide in the cushion.

2. An air cushion unit comprising a base plate and an inflatable air cushion attached to the base plate, wherein the air cushion unit comprises an internal telescopic guide having a first end and a second end, the first end being attached to the base plate and the second end being attached to the top of the air cushion.

3. An air cushion unit according to claim 2, wherein the telescopic guide comprises two rods, wherein the first rod is hollow and the second rod is slidably positioned inside the first rod, so that telescopic action of the telescopic guide is achieved.

4. An air cushion unit according to claim 2, wherein the telescopic guide comprises at least three rods, wherein the rods have increasing diameters and at least two rods are hollow, and wherein a rod having a smaller diameter is slidably positioned inside a rod having a larger diameter, so that telescopic action of the telescopic guide is achieved.

5. Air cushion unit according to claim 2, wherein a shortest length of the telescopic guide corresponds to a cross-sectional height of the air cushion in a folded state, and a longest length of the telescopic guide at least is as long as a cross-sectional height of the air cushion in a completely inflated state.

6. An air cushion unit according to claim 4, wherein a shortest length of the telescopic guide corresponds to a cross-sectional height of the air cushion in a folded state, and a longest length of the telescopic guide at least is as long as a cross-sectional height of the air cushion in a completely inflated state.
