Work principle
|
The chest seal is mainly made of medical hydrogel, non-woven fabric and PET film, which is non-toxic and odorless. With its
original physical viscosity, it can fit human skin very well. This achieves a sealing fit and prevents air from entering. A chest seal does not stop a wound from bleeding. Rather, it works to close off the wound to prevent air from entering the chest cavity. Many versions also have a vent mechanism to allow any air that's already trapped in the chest to leave. |
