Description

Clinical pressurization hemostasis device of department of general surgery Technical Field The invention relates to the technical field of medical appliances, in particular to a clinical compression hemostasis device for general surgery. Background The general surgery department is a special department taking surgery as a main means, the diagnosis and treatment range of the general surgery department covers a plurality of parts such as liver, biliary tract, stomach intestine, blood vessels and the like, various wounds and bleeding during surgery are faced in clinic, and rapid and reliable hemostasis is a key for guaranteeing operation safety and prognosis of patients. In the prior art, chinese patent publication No. CN108720886A discloses a clinical compression tourniquet for general surgery, which is characterized in that a wound is wrapped by a belt body provided with an air cushion, and the air cushion is pressurized by an inflation pressurizing device to realize compression hemostasis. However, this solution has at least the following drawbacks in clinical applications: Firstly, the tourniquet mainly depends on the magic tape to realize winding and fixing of the tourniquet body. After the air cushion is pressurized by the pressurizing device, continuous outward tension can be generated inside the belt body and the air cushion. Under the continuous and possibly large tension action, the adhesive interface of the magic tape is easy to loose slowly and collapse accidentally, the pressurizing action is weakened or lost suddenly, the bleeding is failed and is caused, the medical staff is required to fix again urgently, the treatment process is disturbed, and the definite potential safety hazard exists. Secondly, the air cushion of the tourniquet is usually sewn or fixed at a specific position on the band body, the action point (namely the main pressing area) of the tourniquet relative to the band body is not adjustable, and the wound positions of wounds seen in clinical practice of general surgery are changeable and can be located at irregular positions such as the proximal end, the distal end, the side face or joints of limbs. When the wound position is not matched with the preset position of the air cushion, the pressure generated by the air cushion cannot act on the bleeding point, so that the effective pressure is insufficient or the pressure is dispersed, the hemostatic effect is affected, the tourniquet with various specifications or models is required to be used clinically, and the universality and the use convenience are reduced.
