A ventilated occlusal patch used to treat penetrating chest wounds. It does not allow air to enter the pleural cavity through the wound, but allows air and accumulated blood to escape. The adhesive base of the patch is fixed on the skin.

The patch has a round shape, is elastic and sterile. Thanks to the gel-based glue, it easily adheres to the surface, without the need for preliminary preparation (shaving hair, sterilization, degreasing, etc.). Fits snugly, without gaps and unauthorized air access.
