Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to an anti-pressure sore and foot drop device that helps avoid compressing the patient's limbs together, promotes blood circulation in the patient, and helps prevent the medial malleolus from being crushed. Background Technology

[0002] Pressure ulcers, also known as bedsores or pressure sores, are skin and tissue injuries localized to a specific body position. Prolonged pressure on tissues leads to insufficient blood supply, easily causing skin damage, ulceration, and even necrosis. Pressure ulcers commonly occur in people who are bedridden or sitting for extended periods, especially those with limited mobility and restricted local nerve and blood supply. Long-term bedridden patients experience poor blood circulation due to continuous pressure on the skin, leading to ischemia, hypoxia, and nutrient deficiencies, ultimately resulting in skin necrosis and ulcer formation. Furthermore, the lack of exercise during bed rest, particularly for patients with lower limb disabilities, can easily lead to foot drop and other conditions. Therefore, clinical practice typically involves providing bedridden patients with appropriate pressure ulcer-preventing mattresses. Regular turning and repositioning are also encouraged to improve blood circulation in the compressed tissues, reduce skin and muscle damage from prolonged pressure, and enhance patient comfort.

[0003] Currently, there are turning pillows and pressure ulcer prevention mats available on the market for bedridden patients. However, because patients lack the strength to turn over, it is a physically demanding task that usually requires the assistance of multiple people. Furthermore, most pressure ulcer prevention mats are simply flat pillows; patients often require various support pillows to elevate their limbs to ensure accurate positioning and improve comfort. Therefore, the entire process of turning a patient is quite labor-intensive and time-consuming, placing a heavy burden on caregivers during daily patient care. The patent name is "Pressure Ulcer Prevention Mattress," and the patent number is... Chinese utility model patent ZL202220593591.8, published on 2022-07-26, includes an airbag mattress and a waterbag mattress. The airbag mattress has multiple airbag blocks and an air pump mechanism for inflating and deflating the airbag blocks. The waterbag mattress has multiple waterbag blocks and a water pump mechanism for filling and draining the waterbag blocks. The airbag blocks and waterbag blocks are arranged alternately in a rectangular array. With the above structure, this utility model anti-pressure ulcer mattress can not only effectively distribute body pressure and prevent pressure injuries, but also effectively reduce the patient's body surface temperature, effectively prevent pressure ulcers or bedsores, and improve comfort and sleep quality. However, although the airbag and waterbag pads in this patent can transfer and change the pressure points of the patient's body when lying down to a certain extent, and avoid long-term pressure on a certain part of the patient's body, the patient still needs to use some lifting pillows to help elevate the corresponding limbs to maintain the lying position when other lying positions are required. In addition, due to the lack of a certain structure to support the patient's feet, the patient's feet are prone to drop when lying down, which is inconvenient to use.

[0004] How to solve the above problems has become an urgent technical issue. Utility Model Content
