Step-by-step pressurized and pressure-adjustable limb postoperation pressure bandaging device and bandaging method thereof

Abstract

The invention relates to medical instruments and medical methods, in particular to a step-by-step pressurized and pressure-adjustable limb postoperation pressure bandaging device and a bandaging method of the device. The device is composed of a foot winding and bandaging air bag, a crus winding and bandaging air bag, a knee winding and bandaging air bag, a thigh winding and bandaging air bag, a sealed opening, an air pump, a pressure gage, a check valve or an inflating valve and an arterial-venous foot pump. After the device is wound on and bandages the foot, the crus, the knee and the thigh, the sealed opening is sealed. The method comprises the steps that a clean and soft lining is adopted to bandage the lower limbs, the device is wound on and bandages the foot, the crus, the knee and the thigh, and the sealed opening is sealed; the air pump is started, and the winding and bandaging air bags are pressurized; when pulse pressurization is carried out on the feet, air in the foot winding and bandaging air bag is released out, the arterial-venous foot pump is started, and pulse pressurization is carried out on the feet; after the pressurization is completed, the air is released out, the sealed opening is unfastened, and the device is taken off and disinfected for standby application. The device is simple in structure and complete in function, the method is controllable in operation, bandaging pressure is even, blood circulation, incision union and function restoration are facilitated, thrombosis is avoided, and the probability of incision infection is lowered.

Description

1. Technical field [0001] The invention relates to a medical device and a medical method, in particular to a step-by-step pressurized and adjustable pressure bandaging device and a bandaging method for postoperative limbs. 2. Background technology: [0002] Clinically, many lower extremity operations, such as total knee replacement, total hip replacement, arthroscopy, and high ligation and stripping of varicose veins, require pressure bandaging after surgery. The main purpose is to prevent venous thrombosis, reduce incision bleeding and edema, reduce incision infection rate, facilitate incision healing, relieve local pain, and facilitate functional recovery. At present, various pressurized bandages are mainly used clinically for postoperative limb pressurized dressing. This method has many disadvantages: it is difficult to achieve uniform dressing pressure, and the specific degree of pressure is difficult to control, which can only be judged by the doctor's experience. If ...

AI Technical Summary

Problems solved by technology

This method has many disadvantages: it is difficult to achieve uniform bandaging pressure, and the specific degree of pressure is difficult to control, which can only be judged by the doctor's experience

If the pressure is not enough, the purpose of compression bandaging will not be achieved

If the pressure is uneven or too high, local venous pressure may increase, venous blood stasis may occur, cause thrombus, incision edema, affect incision healing, and even increase the chance of infection
