Description

Adjustable arm pressing hemostasis device

Technical Field

The invention relates to the field of medical treatment, in particular to an adjustable arm pressing hemostasis device.

Background

Blood is an important substance for life. When trauma causes massive bleeding, the amount of which exceeds one fourth of the total body blood volume, life risks. Pressing hemostasis means that after a large artery bleeds, the thumb is pressed against the bleeding blood vessel (proximal end) to close the blood vessel and stop the blood. This is a fast and effective preferred method of hemostasis. After stopping blood, other effective methods for stopping bleeding should be used according to specific situations, such as tamponade hemostasis, tourniquet hemostasis, etc. This method is only temporary. In general, a rescuer wraps the wound with a tourniquet to press an arterial blood vessel at the proximal end of the bleeding part on a bone, so that the blood vessel is blocked and the blood flow is interrupted to achieve the aim of stopping bleeding.

At present, the arm hemostasis mode is mainly carried out through manual pressing, and manual pressing is accurate comprehensive inadequately, and because need press for a long time and make intensity of labour big, complex operation, and current hemostasis equipment of pressing is difficult for carrying, and its laminating degree with the arm is not good, causes the blood of bleeding position to the outside seepage easily, has influenced hemostatic effect, for this reason, we propose an adjustable arm and press hemostasis device.
