Description

Technical Field

[0001] This utility model relates to the field of dressing change auxiliary devices, and in particular to a dressing change chair. Background Technology

[0002] When patients with lower limb injuries undergo dressing changes or suture removal in the hospital, or when medical staff perform treatment procedures on patients in a seated position, foot placement devices are often used to support the patient's feet. Foot placement devices can fully expose the patient's wound, making it easier for medical staff to operate. Currently, patients usually place their feet directly on the foot placement device. Due to the inertia of the foot during the process of putting it down, this will cause a certain impact pressure when the foot lands on the foot placement device, and this impact pressure will cause significant pain to the patient's wound.

[0003] In the existing technology, such as the Chinese patent with authorization announcement number CN217960634U, a foot placement rack for dressing rooms is disclosed. Through the cooperation of connecting plate, compression spring and rubber pad, the foot is cushioned and the pain is reduced when the foot is placed.

[0004] However, the above-mentioned technical solution still has at least the following drawbacks: adjusting the support height requires repeated disassembly and assembly of bolts, and medical staff need to bend over or squat down to complete the operation (the height of the foot support is limited). The cumbersome disassembly and assembly leads to medical staff bending over or squatting for a long time, making it difficult to adjust the support height. Moreover, the required foot support height varies from patient to patient. Frequent and difficult adjustment operations greatly increase the workload of medical staff and reduce the efficiency of dressing change. If adjustment is only made when the height difference is large, the adjustment frequency can be slightly reduced, but the device is difficult to achieve the support effect for different patients. As a result, the device is not suitable for the dressing change needs of different patients, and the support has great limitations. Utility Model Content

Detailed Implementation

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Depend on Figures 1 to 6 The present invention relates to a dressing chair, comprising:

[0029] The support assembly includes a support rod 1, which is fixedly installed inside a first column 2. A second column 3 is sleeved inside the first column 2, and the upper end of the support rod 1 extends into the second column 3.

[0030] The locking assembly includes a locking box 4 and a locking clamp 5. The locking box 4 is located at the bottom end of the second column 3, and the locking clamp 5 is movably installed inside the locking box 4. The locking clamp 5 is used to clamp and fix the bearing rod 1.

[0031] The drive assembly includes a movable rod 6, which is rotatably mounted inside the second column 3. The movable rod 6 is connected to the locking clamp 5 through the locking box 4 to drive the locking clamp 5 to perform opening and closing movements.

[0032] In these embodiments, both the first column 2 and the second column 3 are hollow. The second column 3 can slide inside the first column 2. The support rod 1 is slidably installed with the second column 3, so that the second column 3 can extend into or out of the first column 2. The support rod 1 passes through the locking box 4, so that the locking clamp 5 inside the locking box 4 can clamp and fix it on the support rod 1.

[0033] The movable rod 6, locking clamp 5, and support rod 1 work together. The movable rod 6 rotates, causing the locking clamp 5 to close or open via the locking box 4. This locks or releases the support rod 1. When the locking clamp 5 locks the support rod 1, the support rod 1 is fixed to the second column 3, thus fixing the first column 2 and the second column 3 relative to each other, securing the dressing chair at an appropriate height. When the locking clamp 5 releases its lock on the support rod 1, the support rod 1 can slide through the second column 3, allowing the second column 3 to freely extend into or out of the first column 2, flexibly adjusting the support height of the dressing chair. After adjusting to the appropriate height, the locking clamp 5 is locked back onto the support rod 1 to complete the height adjustment.

[0034] Adjusting the support height of the dressing chair is not only convenient and efficient—simply move lever 17 (details of its working principle are described below)—but also provides flexible and stable support for the patient's feet. The locking clip 5 secures the support rod 1, preventing loosening and slippage. This allows for flexible height adjustment based on patient needs. The stepless adjustment better suits the support requirements of different patients, eliminating the need for medical staff to bend or squat for extended periods. Simply unlocking the chair and raising or lowering the support seat 12 adjusts the chair to the appropriate height, fixing the support height. This significantly reduces the difficulty of adjusting the support height, saving time and effort. The simple and convenient adjustment effectively reduces the workload of medical staff, increases dressing change efficiency, and enhances the chair's flexibility and adaptability, making it more practical.

[0035] In some embodiments of a dressing chair, the locking clamp 5 includes two symmetrically arranged clamping blocks 7, and the inner sidewall of the locking box 4 is provided with a limiting groove 8, and the two clamping blocks 7 can slide relative to or away from each other in the limiting groove 8.

[0036] In these embodiments, the opposing surfaces of the two clamping blocks 7 are each formed with a groove. The bearing rod 1 is tightened and fixed by the cooperation of the two grooves, ensuring a reliable fixation and preventing loosening and slippage, which helps to improve the safety of the support. By sliding the two clamping blocks 7 relative to or opposite to each other in the limiting groove 8, the locking clamp 5 can be stably closed or opened, ensuring the stability and reliability of locking or unlocking.

[0037] In some embodiments of a dressing chair, the locking assembly further includes a threaded rod 9, which is rotatably mounted in the locking box 4. Two clamping blocks 7 are threaded onto the threaded rod 9 through threaded holes, with the helical directions of the threaded holes of the two clamping blocks 7 being opposite.

[0038] In these embodiments, the two ends of the threaded rod 9 are rotatably mounted on the inner sidewalls of the two sides of the locking box 4 via bearings. The threaded rod 9 passes through the threaded holes of the two clamping blocks 7 respectively to achieve threaded connection. Through the opposite threads of the two threaded holes, when the threaded rod 9 rotates, it can drive the two clamping blocks 7 to move relative to or away from each other along the threaded rod 9, ensuring the stability of the locking clamp 5 operation.

[0039] It should be understood that when the locking clip 5 is released, it is only necessary for the grooves of the two clamping blocks 7 to not contact the bearing rod 1. When locked, the two clamping blocks 7 are clamped on the bearing rod 1 to ensure the stable locking of the bearing rod 1. If necessary, anti-slip pads, such as rubber pads, can also be set in the two grooves to further improve the stability and reliability of the clamping and locking.

[0040] In some embodiments of a dressing chair, the drive assembly further includes a first bevel gear 10 and a second bevel gear 11. The second bevel gear 11 is fixedly mounted on the outer ring surface of the threaded rod 9. The bottom end of the movable rod 6 extends into the locking box 4. The movable rod 6 is rotatably mounted on the locking box 4. The first bevel gear 10 is fixedly mounted on the bottom end of the movable rod 6. The first bevel gear 10 and the second bevel gear 11 are meshed together.

[0041] In these embodiments, the second bevel gear 11 can be keyed to the outer ring surface of the threaded rod 9. The first bevel gear 10 is driven by the rotation of the movable rod 6, and then the second bevel gear 11 is driven by the meshing connection, thereby driving the threaded rod 9 to rotate. This enables efficient and stable control of the locking clamp 5, which is beneficial to improving the stability of control and adjustment.

[0042] In some embodiments of a dressing chair, the support assembly further includes a support seat 12, which is fixedly mounted on the top of the second column 3, and the upper surface of the support seat 12 has an arcuate groove 13 for placing the patient's feet.

[0043] In these embodiments, the extension and retraction of the second column 3 drives the support seat 12 to adjust to different height positions, which not only ensures the stability of the support, but also improves the flexibility of adjustment and makes it more convenient to use. Furthermore, the arc-shaped groove 13 can more stably place the patient's feet, making it easier for medical staff to change dressings.

[0044] In some embodiments of a dressing chair, a mounting groove 14 is formed inside the support seat 12, the top end of the movable rod 6 extends into the mounting groove 14, the top end of the movable rod 6 is rotatably mounted on the inner top wall of the mounting groove 14, and an adjustment component for driving the movable rod 6 to rotate is installed in the mounting groove 14.

[0045] In some embodiments of a dressing chair, the adjustment assembly includes a first gear 15 and a second gear 16. The first gear 15 is fixedly installed on the outer ring surface of the movable rod 6, and a rotating shaft is rotatably installed in the mounting groove 14. The second gear 16 is fixedly installed on the outer ring surface of the rotating shaft, and the first gear 15 and the second gear 16 are meshed together.

[0046] In these embodiments, the first gear 15 can be keyed to the outer ring surface of the movable rod 6, the rotating shaft is rotatably mounted in the mounting groove 14 through the bearing, and the second gear 16 is fixedly mounted on the rotating shaft. The rotation of the second gear 16 drives the first gear 15, which in turn drives the movable rod 6 to rotate. The structure is more ingenious and the transmission is more stable. The mounting groove 14 also helps to reduce the space occupied, making the dressing chair more suitable for the complex environment of changing patients' dressings.

[0047] It is important to understand that the number of teeth on the second gear 16 is greater than that on the first gear 15 in order to obtain a larger transmission ratio. Similarly, the first bevel gear 10 is greater than the second bevel gear 11, so that the transmission ratio of the entire gear transmission system meets the adjustment requirements (locking or unlocking can be completed by moving the lever 17 within a certain range).

[0048] In some embodiments of a dressing chair, the adjustment assembly further includes a lever 17, one end of which is fixedly mounted on a rotating shaft. The outer surface of the support seat 12 corresponding to the mounting groove 14 has an arc-shaped opening 18. The lever 17 extends out of the support seat 12 through the arc-shaped opening 18, and the inner sidewall of the arc-shaped opening 18 is slidably mounted to the lever 17.

[0049] In these embodiments, by sliding the lever 17 along the arc-shaped opening 18 (rotating around the pivot), the pivot is driven to rotate, thereby driving the second gear 16 to rotate, which can quickly complete the adjustment of the support height. The operation is more convenient, greatly reducing the difficulty of use and providing greater convenience for medical staff to make frequent adjustments.

[0050] In some embodiments of a dressing chair, a return spring 19 is fixedly installed on the lever 17, and one end of the return spring 19 is fixedly installed on the inner side wall of the mounting groove 14.

[0051] In these embodiments, when the lock is released by the elastic force of the return spring 19, the lever 17 is moved to stretch the return spring 19. When the appropriate height position is adjusted (by pressing or pulling the support seat 12), the lever 17 is released, and the return spring 19 drives the lever 17 to automatically reset, thus completing the locking. This achieves the fixation of the height position of the support seat 12, making the adjustment more flexible and convenient.

[0052] In some embodiments of a dressing chair, a base 20 is fixedly installed at the bottom of the first column 2, and a number of casters 21 are fixedly installed on the lower surface of the base 20.

[0053] In these embodiments, the combination of several casters 21 and base 20 can improve the stability of the chassis and make the dressing chair more flexible, which is conducive to improving the convenience of use.

[0054] When the support height needs to be adjusted, the lever 17 is moved along the arc-shaped opening 18 to the other end. Through the cooperation of the first gear 15, the second gear 16, the movable rod 6, the locking clamp 5, and the bearing rod 1, the locking clamp 5 can be quickly released. Then, the bearing seat 12 can be flexibly pressed or pulled to the appropriate height position. After that, the lever 17 is released, and under the action of the return spring 19, the lever 17 is automatically reset, thereby locking the locking clamp 5 and clamping and fixing the bearing rod 1, so that the bearing seat 12 is fixed in the adjustment position. Thus, the support height of the dressing chair can be adjusted. The stepless adjustment can better suit the support needs of different patients, and does not require medical staff to bend over or squat for a long time, greatly reducing the difficulty of adjusting the support height, saving more time and effort, effectively improving the flexibility and adaptability of use, and making it more practical.
