Description

Technical Field

[0001] The utility model relates to the technical field of walkers, in particular to a walker for postoperative rehabilitation training. Background Art

[0002] A walker is one of the equipment for rehabilitation care, which can help patients support their weight, maintain balance and walk. After undergoing surgery, cardiothoracic surgery patients usually need to use a walker for certain rehabilitation training and care in order to recover quickly.

[0003] According to the description of a postoperative rehabilitation nursing walker disclosed on the patent website (authorization announcement number: CN 220237301 U), "The utility model discloses a postoperative rehabilitation nursing walker, which belongs to the field of postoperative rehabilitation devices and solves the problem of inconvenience in hanging the chest closed drainage bottle of the existing walker. It includes a support frame with an opening on one side, and the other three sides of the support frame are provided with an upper connecting rod and a lower connecting rod arranged at intervals. The four corners of the bottom of the support frame are provided with a height adjustment mechanism, and the bottom of each height adjustment mechanism is provided with a universal wheel with a brake device. Two sliding rings are slidably provided on the lower connecting rod on the side adjacent to the open side of the support frame, and the bottoms of the two sliding rings are connected to hooks. A tray is provided below the hook, and the two sides of the tray are fixedly connected to the lower connecting rod by a pull rod. The walker of the utility model can facilitate the hanging of the chest closed drainage bottle and protect it to prevent the chest closed drainage bottle from falling off, thereby further improving the comfort of the patient."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the device slides inside the sleeve through the support frame and positions the adjustable height of the support frame through the anti-top screw, but the anti-top bolt presses against the support frame and fixes the support frame by increasing friction, when the device is in use, the patient holds the support frame with his hand and puts the weight of his body on the support frame. After long-term use, the anti-top bolt will loosen and disengage from the support frame, causing the support frame to suddenly drop, which will cause the patient to lose support and fall and get injured. Therefore, it is necessary to improve a walker for postoperative rehabilitation training to solve the above problems. Utility Model Content
