Abstract
Description
Technical Field
[0001] This utility model relates to the field of bone and joint dressing change aids, specifically a bone and joint dressing change aid. Background Technology
[0002] As is well known, joints are formed by sacs of connective tissue connecting adjacent bones. The indirect connection between bones is called a joint. There are cavities between opposing bone surfaces, which contain a small amount of synovial fluid. It has a large range of motion. Each joint has articular surfaces, joint capsules, and joint cavities. Some joints also have auxiliary structures such as ligaments, articular discs, and menisci. If a joint is injured, it is usually operated on by a surgeon. After the operation, the wound needs to be dressed. Joint dressing aids are mainly used to help medical staff stabilize the patient's limbs when changing joint dressings, providing convenient assistive tools and preventing the patient's limbs from shaking during the dressing change process.
[0003] While existing joint dressing change aids can support the joint during use, they are not convenient for adjusting the angle of joint rotation or for adjusting the support position according to the fixed angle of the patient's limb. They can also easily cause limb stretching during dressing changes. Therefore, we propose a joint dressing change aid to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This utility model includes a mobile trolley 1. A first telescopic rod 2 is located at the top center of the mobile trolley 1. A first limb support 3 is located at the top of the first telescopic rod 2. A semi-circular angle adjustment groove 4 is located at the bottom right end of the first telescopic rod 2. The semi-circular angle adjustment groove 4 is marked with angle scales to facilitate determining the adjustment angle of the joint dressing aid. A second telescopic rod 5 is located at the right end of the first telescopic rod 2. A second limb support 6 is located at the top of the second telescopic rod 5. An angle adjustment slider 7 is located at the bottom end of the second telescopic rod 5. The angle adjustment slider 7 cooperates with the semi-circular angle adjustment groove 4. The cooperation between the angle adjustment slider 7 and the semi-circular angle adjustment groove 4 is a sliding fit, allowing the angle adjustment slider 7 to slide along the semi-circular angle adjustment groove 4 for adjustment. A sliding adjustment mechanism is located at the left end of the second telescopic rod 5. The sliding adjustment groove 8 cooperates with the first telescopic rod 2. The sliding adjustment groove 8 and the first telescopic rod 2 are in a sliding fit, allowing the sliding adjustment groove 8 to slide along the first telescopic rod 2. A hand-tightening fixing bolt 9 is provided at the left end of the sliding adjustment groove 8. The edges of the mobile cart 1, the first telescopic rod 2, the first limb frame 3, the semi-circular angle adjustment groove 4, the second telescopic rod 5, the second limb frame 6, the angle adjustment slider 7, the sliding adjustment groove 8, and the hand-tightening fixing bolt 9 are all rounded, so that the joint dressing change assist will not scratch the user during use. The joint dressing change assist can support the joint during use and facilitates adjustment of the patient's joint rotation angle. The support position can be adjusted according to the fixed angle of the patient's limb, and it will not cause limb stretching during dressing changes.
[0022] In summary, this joint dressing change aid, when in use, first determines the adjustment angle of the second limb frame 6 based on the angle of the patient's limb fixation. The angles of the second telescopic rod 5 and the second limb frame 6 are adjusted through the cooperation between the sliding adjustment groove 8 and the first telescopic rod 2, and the cooperation between the angle adjustment slider 7 and the semi-circular angle adjustment groove 4. The patient's limb is then fixed between the first limb frame 3 and the second limb frame 6, thus allowing limb positioning without adjusting the patient's limb fixation, thereby supporting the patient's joint and facilitating dressing changes by medical staff.
[0023] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
