Description

An adjustable arm pressing hemostasis device

technical field

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

Background technique

Blood is an important substance to maintain life. When trauma causes massive bleeding, the amount of bleeding exceeds a quarter of the blood volume in the whole body, and life will be in danger. The method of pressing to stop bleeding refers to pressing the top of the bleeding vessel (near the heart) with your thumb after a large artery bleeds, so that the blood vessel is closed and the blood is interrupted. It is a fast, effective and preferred method of hemostasis. After the bleeding is stopped, other effective hemostasis methods should be used according to the specific situation, such as packing hemostasis, tourniquet hemostasis, etc. This method is only a temporary one. In our daily life, it is inevitable that we will be injured and bleed, which requires timely treatment of the bleeding. In general, the rescuer wraps the wound with a tourniquet to press the artery near the bleeding site on the bone, so that the blood vessels Occlusion, interruption of blood flow to achieve the purpose of hemostasis.

At present, the arm hemostasis method is mainly carried out by manual pressing, which is not accurate and comprehensive enough, and the labor intensity is high and the operation is cumbersome due to the need for long-time pressing, and the existing pressing hemostasis equipment is not easy to carry, and its fit with the arm is not good Good, it is easy to cause the blood at the bleeding site to leak to the outside, which affects the effect of hemostasis. Therefore, we propose an adjustable arm pressing hemostasis device.
