Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical bandage technology, and in particular to a hip joint modular postoperative fixation bandage. Background Technology
[0002] Medical bandages are primarily used to immobilize or bandage wounds to aid healing or prevent further injury. They are commonly used in medical emergencies, surgical procedures, and the treatment of sports injuries. After orthopedic surgery, immobilizing the surgical site with bandages is a crucial step. It stabilizes fractures or surgical areas, preventing bone or joint movement during the healing process and promoting proper healing. Immobilizing the injured area reduces unnecessary movement and stress, thereby alleviating pain and discomfort, protecting it from further external forces or accidental impacts, and lowering the risk of secondary injury. Furthermore, bandage immobilization helps tissues, bones, and joints heal faster, improving recovery outcomes; it also reduces and controls postoperative swelling, preventing hematomas or fluid accumulation.
[0003] For hip joint wounds, the commonly used bandages are currently one-piece fixation bandages. One-piece fixation bandages have the following problems when used to fix the hip joint: 1. Due to patient movement or movement, the bandage is prone to slipping off, leading to exposure of the surgical site and affecting wound healing. 2. Most commonly used one-piece fixation bandages are made of elastic or cotton materials, which are easily contaminated by urine and feces when applying pressure to the groin. 3. In pelvic tumor surgery or hip replacement surgery, there is a problem of occult bleeding. Using ordinary one-piece fixation bandages cannot ensure even pressure distribution on the hip joint, thus failing to address occult bleeding. Pressure bandaging is a routine method of hemostasis. Postoperative bleeding with pressure bandaging is lower than with negative pressure suction, reducing postoperative anemia. Pressure bandaging also reduces patient anxiety, improves comfort, and means less trauma. (Sun Jianhui. Comparison of the effects of pressure bandaging and negative pressure drainage in preventing postoperative blood loss after total hip arthroplasty. Practical Medicine Journal, 2010(27):3.)
[0004] Therefore, in view of the problems existing in the above-mentioned technologies, there is an urgent need to study a hip joint modular postoperative fixation bandage to achieve effective pressure fixation of the wound at the hip joint. Utility Model Content
