Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a walking aid for medical care. Background Art

[0002] At present, patients who have undergone lower limb orthopedic surgery and patients with upper and lower limb fractures in clinical practice mostly use walkers for postoperative exercise and recovery of walking during rehabilitation exercises. Walkers are mostly used for patients who need functional exercises, such as: the elderly after orthopedic surgery, patients after hip and knee replacement surgery, and other disabled people who have no confidence in maintaining balance while walking, can also use walkers to assist them in walking.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "walker", and its application number is "CN202320568434.6". The patent mainly includes a frame, a roller is arranged at the bottom end of the frame, and the roller is provided with a brake groove, which is a gradually rising spiral surface. The frame is also provided with a handle, and the handle is connected with a brake line, and the brake line is connected to the brake pad, and the brake pad can be pressed into the brake groove. The frame is moved by the roller at the bottom end of the frame to facilitate the movement of the walker. After the movement, when the user uses the force to move the body, the brake line can be driven by the handle to press the brake pad into the brake groove of the roller to fix the roller. After the brake pad is pressed into the brake groove, the contact area between the brake pad and the brake groove will gradually increase when rolling forward, and the movement resistance of the walker will gradually increase, so that the walker is fixed more stably, and the walker is convenient to move steadily with the force, thereby solving the technical problem of easy positive slippage in the existing roller-type walkers. However, when the patient faces stairs, the walker is difficult to assist the patient to climb the stairs, which often causes the patient to be unable to climb the stairs or the patient to fall. Therefore, we propose a medical care walker to solve the above-mentioned problems. Utility Model Content
