Technical Field
[0001] This utility model belongs to the field of nursing equipment technology, specifically relating to a knee hot and cold compress device. Background Technology
[0002] The knee joint is the most complex joint in the body, with the highest incidence of acute sports injuries and chronic overuse injuries. Swelling and pain in the knee are also the most common complications. Lower limb fractures, knee ligament injuries, and synovial edema that occur during sports can all lead to knee swelling. Chronic conditions such as rheumatoid arthritis, gouty arthritis, and knee osteoarthritis can also cause knee swelling. Long-term swelling can accelerate knee joint degeneration, ultimately reducing patients' daily living abilities and even requiring surgery, severely impacting their quality of life.
[0003] For knee joint swelling and pain caused by various acute and chronic injuries, cold therapy and heat therapy are the most commonly used treatments. In the early stage (within 24-48 hours) after an acute closed injury, cold therapy, such as ice packs, is often used to reduce exudation and bleeding. 3-5 days after an acute injury, if there is no bleeding or infection, alternating between cold and heat therapy can be used. For example, applying cold compresses for a period followed by heat compresses can promote vasoconstriction and vasodilation, accelerating the absorption of edema. In the chronic phase after injury or the recovery period of chronic lesions, heat therapy is usually used to relieve muscle tension, reduce pain, and improve local blood circulation. Currently, commonly used cold therapies include cold compresses, ice massage, showering, soaking, and cold sprays, while heat therapies include hot compresses, steaming, infrared therapy, and paraffin therapy. Among these, cold compresses and heat compresses are the most commonly used and convenient. The following problems exist in current treatment: 1. Applying cold compresses directly with water bags may cause frostbite and render the treatment ineffective; 2. Applying hot compresses directly with water bags is difficult to control the temperature, which may be ineffective or cause burns.
