Description

Technical Field

[0001] The utility model relates to the technical field of first aid tools, in particular to an abdominal pressure tourniquet. Background Art

[0002] The abdominal compression tourniquet is a common first aid tool used to control abdominal bleeding in combat trauma and traumatic environments.

[0003] The main methods for controlling abdominal bleeding in war trauma and traumatic environment are: 1. Abdominal bandage: Abdominal bandage is a traditional method of hemostasis, which is still commonly used in battlefield first aid. It usually uses absorbent gauze or bandages to cover the wound. It can be quickly implemented in the absence of professional equipment and applies appropriate pressure to control bleeding; 2. Manual compression: In the absence of professional hemostasis tools or the inability of first aid personnel to obtain these tools immediately, manual compression is a simple but effective method of hemostasis; medical staff can directly apply pressure to the abdominal wound with their hands to control bleeding as soon as possible. There are the following technical defects: 1. At present, triangular bandages or gauze are mainly used for abdominal compression hemostasis on the battlefield, and the pressure area is small and the pressure is insufficient; 2. Manual compression requires continuous manual operation, and may not be effective enough when facing complex wounds or heavy bleeding, and it is not convenient for the transfer of wounded; 3. Abdominal bandage is not as effective as abdominal pressure tourniquet in controlling heavy bleeding; it cannot be used for both local abdominal compression and overall compression.

[0004] Therefore, how to design an abdominal compression tourniquet that can be implemented quickly and continuously has become an urgent problem to be solved. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides an abdominal pressure tourniquet to solve at least one of the above technical problems.

[0006] The technical solution of the utility model is: an abdominal pressure tourniquet, comprising an abdominal belt, on which a tightening device is arranged, the tightening device adopts a tightening belt, and the tightening belt is provided with Velcro; a pressure device is arranged on the inner wall of the abdominal belt, the pressure device comprises a plurality of air bags arranged at intervals, a gas diversion structure is arranged on the outer surface of the abdominal belt, all the air bags are connected to the inflation device through the gas diversion structure, and the gas diversion structure can connect all the air bags, or connect one air bag separately.

[0007] The utility model adopts a Velcro on the tightening belt, which can quickly fix the abdominal belt on the patient's abdomen; when an inflation device is used to connect an airbag separately through a gas shunt structure, the airbag is inflated separately to locally pressurize the wound, and the pressurized airbag area can be selected according to the wound position; when the amount of abdominal bleeding is large, the inflation device is used to connect all the airbags through the gas shunt structure, and all the airbags can be inflated at the same time to achieve the effect of pressurizing the abdomen as a whole. When the overall pressurization occurs, since there are gaps between the airbags, they can fit the abdomen well and achieve the effect of continuous pressurization; it can be used for both local compression of the abdomen and overall compression.
