Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a hemostasis compressor.
Background
In soldier exercise or actual combat, often can be injured, need in time to stop bleeding. The tourniquet is widely applied in medical operations and rescues, the tourniquet can reduce the amount of bleeding at an affected part, avoid the reduction of blood pressure, ensure the clear visual field of operations, facilitate the operation of an operator, shorten the operation time, relieve the operation pain of a patient and provide favorable conditions for the postoperative rehabilitation of the patient.
However, when the femoral artery or the carotid artery has a large hemorrhage, a general tourniquet cannot be used at the position of the groin or the neck, and the following reasons are generally provided: 1. because the area of the tourniquet required when the groin or the neck part stanchs is particularly large, the common tourniquets are narrow and are not wide enough to stanch; 2. when the groin or the neck of the patient bleeds greatly, the tourniquet needs to have higher pressure, the common tourniquet cannot provide higher pressure and needs the medical staff to use the knee joint to resist the pressure, so that time and labor are wasted, and the labor intensity of the medical staff is increased; 3. the tightness of the tourniquet is not well adjusted, if the tightness is too loose, the hemostasis effect is not achieved, the vein backflow is blocked due to the too tight tightness, the bleeding is increased, and the tourniquet needs to be replaced.
Therefore, it is a technical problem to be solved by those skilled in the art how to provide a hemostatic compressor with a simple structure and capable of providing a large pressure for the groin and neck.
