Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an oxygen therapy combined device for preventing and treating pressure ulcers. Background Art

[0002] Pressure ulcers, also known as bedsores or pressure sores, are one of the common complications of patients who are bedridden or sedentary for a long time. They usually occur on the skin and / or underlying tissues, and due to long-term pressure, blood circulation is blocked, which in turn leads to tissue damage and necrosis. Pressure ulcers not only bring great pain to patients, but also increase medical costs and the difficulty of nursing.

[0003] At present, the treatment of pressure ulcers mainly relies on traditional methods such as decompression, wound cleaning, use of antibiotics, and nutritional support. These methods often require a long treatment process, and the treatment effects vary from person to person, making it difficult to meet the need for rapid healing. Since pressure ulcers mostly occur in areas with poor blood circulation, traditional treatment means are difficult to effectively promote blood circulation and tissue repair, resulting in a slow healing process. Long-term bed rest or the use of traditional decompression devices may further reduce the quality of life of patients and increase the psychological and physical burden on patients. The treatment and management of pressure ulcers require a large amount of medical resources, including the time and energy of medical staff, medical equipment, and drugs. Even after treatment, pressure ulcers are prone to recurrence, especially when patients are unable to effectively change their bedridden or sedentary state. Therefore, it is necessary to invent a new and effective device for preventing and treating pressure ulcers to improve the oxygenation level of local tissues, promote blood circulation, and accelerate tissue repair, thereby effectively preventing and treating pressure ulcers. Summary of the Invention

[0004] The purpose of the utility model is to provide an oxygen therapy combined device for preventing and treating pressure ulcers to solve the technical problems of poor treatment effect, easy recurrence, time-consuming, laborious, and costly in the traditional treatment methods of pressure ulcers.
