Because the contact surface of the transparent pressing air bag and the skin is changed along with the inflation degree of the transparent pressing air bag, the more the transparent pressing air bag is inflated, the larger the contact surface of the transparent pressing air bag and the skin is, and the larger the pressing force is. Through adjusting the air volume of inflating, medical personnel can adjust the size of oppression face and oppression dynamics, avoid excessive oppression-the observation patient finger has cyanosis's condition to adjust the atmospheric pressure properly, make transparent oppression gasbag can stanch and can not oppress excessively. Meanwhile, the bandage and the compression air bag are transparent, so that medical personnel and patients can accurately judge whether the air bag presses a bleeding point or not to adjust, and dislocation is avoided. After a proper time, the air pressure of the air bag is reduced by air suction, the presence or absence of the blood seepage is observed, the pressure is continuously reduced to be free of the pressure, and the hemostat can be released if the blood seepage is free. Compare in current haemostat, this haemostat can be through to the gasbag on the transparent bandage aerifing the point of bleeding of oppression to accurate control oppression area, oppression dynamics and oppression position avoid bringing the discomfort for the patient.
