Description

Technical Field

[0001] The invention relates to the technical field of medical bandages, in particular to a hip joint assembled postoperative fixation bandage. Background Art

[0002] Medical bandages are mainly used to fix or bandage wounds to help them heal or prevent further injury. They are usually used in medical emergency, surgical operations, and the treatment of sports injuries. After orthopedic surgery, using bandages to fix the surgical site is a very important step. It can stabilize the fracture or surgical area and prevent the bone or joint from moving during the healing process, thereby promoting proper healing. By fixing the injured part, unnecessary movement and pressure can be reduced, thereby reducing pain and discomfort, protecting it from further external forces or accidental impacts, and reducing the risk of secondary injuries. In addition, using bandages to fixate can help tissues, bones, and joints heal faster, improve rehabilitation effects, reduce and control postoperative swelling, and prevent hematomas or effusions.

[0003] For wounds at the hip joint, the commonly used bandages are all one-piece fixed bandages. The one-piece fixed bandage has the following problems when fixing the hip joint: 1. Due to the patient's activities or movement, the bandage is prone to fall off, resulting in exposure of the surgical site and affecting wound healing. 2. The commonly used one-piece fixed bandages are mostly made of elastic materials and cotton materials, which are easily contaminated by urine and feces when the pressure bandage is applied to the root of the thigh. 3. There will be hidden bleeding problems in pelvic tumor surgery or hip replacement surgery. The use of ordinary one-piece fixed bandages cannot ensure that the pressure bandage on the hip joint is uniform, and thus cannot solve the problem of hidden bleeding. Pressure bandage is one of the conventional methods of hemostasis. The amount of postoperative bleeding using pressure bandage is lower than that using negative pressure suction method, which can reduce the phenomenon of postoperative anemia. The use of pressure bandage can reduce the patient's fear and improve comfort. Pressure bandage means less trauma. (Sun Jianhui. Comparison of the effects of pressure bandage and negative pressure drainage in preventing blood loss after total hip replacement surgery, Practical Medicine Journal, 2010(27): 3.)
