Description

A kind of auxiliary device for dressing of penetrating injury of knee joint

technical field

The invention relates to the field of emergency aids, in particular to an auxiliary device for bandaging knee joint penetrating injuries.

Background technique

The main components of the knee are the meniscus and ligaments. The knee is very vulnerable to injury during exercise or under special circumstances. Penetrating knee injury is a more serious injury to the knee. In areas such as disaster sites, emergency medical treatment of the wounds, such as disinfection, hemostasis, bandaging, etc., is required when the injured have penetrating injuries.

When bandaging the knee of the injured person, the injured person is generally in a lying position, so the injured person will frequently move the wounded part of the injured person when the wound is bandaged, which will increase the pain of the patient. When it is transferred, it will also bend the knee of the injured person, causing problems such as bleeding from the wound of the injured person.
