Description

Technical Field

[0001] The utility model relates to the technical field of anti - bedsore appliances, in particular to an anti - bedsore device for bedridden patients. Background Art

[0002] Pressure ulcers, also known as pressure sores and decubitus ulcers, are caused by long - term local tissue compression, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis.

[0003] When nursing bedridden patients (such as patients with leg fractures) to prevent pressure ulcers, an anti - bedsore mat is used under the patient's buttocks. However, the existing mats can only provide soft support for the patient's buttocks. For example, an anti - bedsore mat disclosed in the patent with the publication number CN 205586182 U supports the patient's buttocks through an inflatable gasket and cannot perform soft padding on the patient's back. Therefore, there is an urgent need for an anti - bedsore device for bedridden patients that can support both the patient's buttocks and back with soft padding. Summary of the Utility Model

[0004] The utility model provides an anti - bedsore device for bedridden patients to solve the problems in the prior art.
