Traumatic hemorrhage hemostasis model adopting air pressure sensor and usage method thereof

Abstract

The invention discloses a traumatic hemorrhage hemostasis model adopting an air pressure sensor and a usage method thereof. The model comprises a cyclic-type air pressure sensing air bag, a pressure sensor connected to the cyclic-type air pressure sensing air bag, a control system electrically connected to the pressure sensor, a blood system electrically connected to the control system and a pressure balance water sac which is connected to the blood system and is used for adjusting pressure in the blood system. The control system can regulate and control blood flowing in the blood system. In a usage state, a medical hemostatic bandage binds the cyclic-type air pressure sensing air bag. By using the traumatic hemorrhage hemostasis model, binding pressure at any angle is equal, traumatic hemorrhage hemostasis operation training can be performed on medical care personnel so that the medical care personnel can rapidly and skillfully grasp hemostatic operation.

Description

technical field [0001] The invention relates to a wound bleeding hemostasis model, in particular to a wound bleeding hemostasis model using an air pressure sensor and a use method thereof. Background technique [0002] Trauma bleeding is the most common accidental injury we encounter. Whether it is a knife cut or a car accident, it needs to be dealt with as soon as possible. The most common trauma in our lives ranges from small cuts and scratches to large areas of bleeding after trauma. Generally, the blood volume of an adult is 7%-8% of the body weight (about 4000-5000mL). When the blood loss exceeds 15% of the blood volume, the blood pressure will drop, and symptoms such as thirst and cold sweat will appear; when it exceeds 40%, Life will be threatened, and symptoms such as unconsciousness and shock will appear. Therefore, in trauma first aid, rapid hemostasis is the most important, and the bandage pressure must be uniform to stop bleeding. [0003] At present, the dome...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a wound bleeding hemostasis model using an air pressure sensor and its use method. This model solves the problems of difficult operation and unstable banding pressure in the prior art. The banding pressure at any angle is equal, which can help medical staff Train trauma bleeding hemostasis operation, so that medical staff can quickly and proficiently master hemostasis operation
