Description

Technical Field

[0001] The utility model relates to the technical field of medical brackets, in particular to a foot bracket for dressing changes. Background Art

[0002] When hospitals change the dressings of patients with foot trauma, they usually need to support the patient's legs or feet to facilitate the doctor to change the dressings of the patient's feet. Among them, diabetic foot is a serious diabetic complication that threatens diabetic patients. It is a foot disease caused by loss of sensation due to neuropathy or loss of mobility due to ischemia and infection. It is mainly manifested as deep skin ulcers, gangrene of the extremities and other lesions. Since the wound healing speed of diabetic foot is slow, continuous and effective treatment of foot wounds is required. In the prior art, the announcement number CN219166956U discloses a foot dressing support. When this device is used, the medical staff rotates four handles in a positive direction, so that the four threaded rods move downward, and then the four bases can move downward until the lower surfaces of the four bases contact the ground, and the friction between the four bases and the ground is used to increase the stability of the device. However, it is time-consuming and laborious to continuously turn the four sets of handles to rotate, and to a certain extent, it increases the workload of medical staff. Utility Model Content
