Technical Field
[0001] The utility model relates to the technical field of medical care appliances, in particular to an inflatable heel pressure relief pad for preventing pressure injuries. Background Art
[0002] Pressure injury refers to the ulceration and necrosis of local tissues caused by long-term pressure on local tissues, which leads to blood circulation disorders and nutritional deficiencies. For patients who are bedridden for a long time, foot pressure injuries account for 1 / 5 to 1 / 4 of all pressure injury cases, and are the most common site for foot pressure injuries. Heel pressure injuries are difficult to heal, and the course of the disease is long, which will greatly increase the mortality rate and amputation rate of patients. In clinical practice, air mattresses are commonly used to prevent pressure sores on the feet, but they have little effect on preventing pressure injuries on the feet. Once a pressure injury occurs, it will not only increase the patient's pain and affect the patient's treatment, but also increase medical costs.
[0003] Prior art, such as announcement number CN215384925U, provides a decompression sleeve for preventing heel pressure sores; it includes an elastic sleeve and a soft rubber decompression pad; a viewing window is opened at the lower rear portion of the elastic sleeve; the soft rubber decompression pad is arranged in the viewing window, and its front peripheral edge is connected to the inner edge of the viewing window; the elastic sleeve has an L-shaped longitudinal section, an upper ring is opened at the upper rear portion, and a lower ring is opened at the front portion. Effect: The elastic sleeve has elasticity and tension. After the patient puts on socks, the present application can be directly and quickly put on the outside of the patient's socks, and the soft rubber decompression pad can wrap the patient's heel, or the present application can be directly put on the outside of the patient's ankle to wrap the patient's heel. The relevant operation is quick and convenient, and the present application can be applied when the patient wears slippers or shoes. After the elastic sleeve of the present application is arranged outside the patient's ankle, it is not easy to shift forward and backward and up and down, so that the wearing is stable and not easy to slip off, so that the patient's heel is wrapped and the decompression effect is good, which can better reduce the pressure injury of the patient's heel. Therefore, the present application is highly practical.
[0004] In actual use, due to the difference in the size of the patient's foot, it is necessary to select a pressure relief pad that is suitable for the patient when using it. However, in order to meet the needs of different patients, the pressure relief pad is usually one-size-fits-all. Although the pressure relief pad itself has a certain elasticity, it will reduce the comfort of use when it is not matched. In view of this, we propose an inflatable heel pressure relief pad to prevent pressure injuries. Utility Model Content
