Description

Pressurization hemostasis band-aid

Technical Field

The utility model relates to a wound plaster, in particular to a pressure hemostasis wound plaster.

Background

When a body has a small scratch wound or a puncture wound caused by injection therapy, the common adhesive bandage is not tightly attached and cannot provide large pressure for the wound to stop bleeding, and particularly, the wound is positioned at a position which can be wound and attached by the adhesive bandage, such as a non-finger position, a toe position and the like, and the finger is additionally used for pressing to stop bleeding. The existing pressurizing wound plaster can pressurize a wound, but the designed pressurizing module has a complex structure and is not convenient to use.
