Description

Technical Field

[0001] This utility model relates to the field of neurological nursing technology, and in particular to a limb function exercise device. Background Technology

[0002] Neurological diseases are often accompanied by limb motor dysfunction, such as hemiplegia caused by stroke, paraplegia caused by spinal cord injury, and motor coordination disorders caused by traumatic brain injury, resulting in decreased limb mobility. Therefore, neurology departments are often equipped with limb function training devices to facilitate limb rehabilitation training for patients.

[0003] To facilitate rehabilitation training for patients, existing hospital beds are equipped with some limb function exercise devices. However, during patient use, the devices inevitably become contaminated with bacteria and viruses, especially on the parts of the exercise device that patients frequently touch. Spray disinfection may miss some of the parts that patients frequently touch, causing cross-infection among patients.

[0004] Therefore, there is a need for a limb function training device that can thoroughly disinfect areas that patients frequently come into contact with. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a limb function training device. By forcefully rotating a roller with the limbs, the roller surface passes sequentially over cleaning blocks. The cleaning blocks use disinfectant from a storage tank to clean the roller surface, ensuring that the contact areas of the patient on the training device are thoroughly sterilized and disinfected, thus preventing cross-infection among patients.

[0006] This utility model is achieved through the following technical solution: a limb function exercise device is provided, including an exercise mechanism installed on a bed; a roller is rotated at the supporting end of the exercise mechanism, and a liquid storage tank with its opening facing the roller is fixed on the exercise mechanism. A cleaning block that slides towards the roller is provided in the liquid storage tank, and the cleaning block is connected to the liquid storage tank through a return spring A; the patient rotates the roller by forcefully rotating the roller with their limbs, so that the surface of the roller passes through the cleaning block in sequence. The cleaning block cleans the surface of the roller with disinfectant in the liquid storage tank, thereby ensuring that the patient's contact parts on the exercise mechanism can be fully sterilized and disinfected, and avoiding cross-infection among patients.

[0007] As an optimization, the cleaning block is provided with a through hole, and the through hole is provided with a liquid suction block extending into the liquid storage tank, and the movement trajectory of the liquid suction block intersects with the surface of the roller; the liquid suction block transfers the disinfectant in the liquid storage tank to the roller, thus preventing the disinfectant in the liquid storage tank from separating from the cleaning block.

[0008] As an optimization, a cleaning cylinder extending along the roller axis is rotated on the cleaning block. The movement trajectory of the cleaning cylinder intersects with the surface of the roller, and the surface of the cleaning cylinder is fitted to the liquid absorption block. The cleaning cylinder reduces the friction between the roller and the cleaning block, thereby reducing the wear of the cleaning block.

[0009] As an optimization, the exercise mechanism is equipped with a cleaning block extending along the roller axis, and the cleaning block is in contact with the surface of the roller; the cleaning block removes the disinfectant adhering to the roller and prevents the roller from slipping.

[0010] As an optimization, a connecting rod is hinged to the exercise mechanism, the cleaning block is fixed on the connecting rod, and a return spring B is provided on the exercise mechanism to drive the cleaning block to move toward the roller; the cleaning block is driven to move toward the roller by the return spring B to prevent the cleaning block from detaching from the roller.

[0011] As an optimization, the side of the roller has several cross-sections extending along the roller axis, and the cross-sections are arranged around the roller axis; the cross-sections make it easier for the patient to control the roller and prevent the patient's limbs from slipping on the roller.

[0012] The beneficial effects of this invention are as follows: Patients rotate the roller by applying force with their limbs, causing the roller surface to pass sequentially over cleaning blocks. The cleaning blocks clean the roller surface with disinfectant from the storage tank, ensuring that the patient's contact points on the exercise equipment are adequately sterilized and disinfected, preventing cross-infection. The suction block transfers the disinfectant from the storage tank to the roller, preventing separation between the disinfectant and the cleaning blocks. The cleaning cylinder reduces friction between the roller and the cleaning blocks, minimizing wear on the cleaning blocks. The cleaning blocks remove disinfectant adhering to the roller, preventing slippage. The cut surface facilitates patient control of the roller, preventing slippage of the patient's limbs.

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figures 1-3The limb function training device of this utility model includes a training mechanism 2 installed on a bed 1; a roller 3 is mounted on the supporting end of the training mechanism 2; a liquid storage tank 4 with an opening facing the roller 3 is fixed on the training mechanism 2; a cleaning block 5 is provided in the liquid storage tank 4 and slides towards the roller 3; the cleaning block 5 is connected to the liquid storage tank 4 through a return spring A6.

[0016] The exercise mechanism 2 is existing technology, including a support 201 hinged to the bed 1, a counterweight 202 at one end of the support 201, a roller 3 located at the end of the support 201 away from the counterweight 202, and a fixing device 12 for fixing the support 201 to prevent the exercise mechanism 2 from shaking when idle.

[0017] Before using the exercise device 2, the patient rotates the roller 3 by force with their limbs. The cleaning block 5 is always in contact with the surface of the roller 3 under the drive of the return spring A6. The surface of the roller 3 passes through the cleaning block 5 in turn. The cleaning block 5 absorbs the disinfectant in the storage tank 4 and cleans the surface of the roller 3 in turn. At the same time, the disinfectant on the surface of the roller 3 disinfects the limb parts of the patient that come into contact with the exercise device 2.

[0018] like Figure 1 and Figure 2 The cleaning block 5 shown has a through hole, and the through hole has a liquid suction block 7 extending toward the liquid storage tank 4. The movement trajectory of the liquid suction block 7 intersects with the surface of the roller 3.

[0019] The liquid-absorbing block 7 transfers the disinfectant from the liquid storage tank 4 and applies the disinfectant to the surface of the roller 3 in sequence.

[0020] like Figure 1 and Figure 2 The cleaning block 5 shown is provided with a cleaning cylinder 8 extending along the axial direction of the roller 3. The movement trajectory of the cleaning cylinder 8 intersects with the surface of the roller 3, and the surface of the cleaning cylinder 8 is fitted with the liquid absorption block 7. The liquid absorption block 7 is existing technology and can be made of a sponge pad or the like with water absorption properties.

[0021] The patient rotates the roller 3 by using their limbs, which causes the cleaning cylinder 8 to rotate on the cleaning block 5. The cleaning cylinder 8 rotates on the suction block 7, and the disinfectant on the suction block 7 is sequentially absorbed onto the surface of the cleaning cylinder 8. The disinfectant absorbed onto the surface of the cleaning cylinder 8 then cleans the surface of the roller 3.

[0022] like Figure 1 and Figure 2 The exercise mechanism 2 shown is provided with a cleaning block 9 extending along the axial direction of the roller 3. The cleaning block 9 and the surface of the roller 3 are in contact. The cleaning block 9 is existing technology and can be made of a sponge pad or the like with water absorption.

[0023] The patient rotates the roller 3 clockwise, and the disinfectant on the surface of the roller 3 disinfects the limbs of the patient that come into contact with the exercise device 2; the patient rotates the roller 3 counterclockwise, and the cleaning block 9 cleans the surface of the roller 3 in turn until the disinfectant on the surface of the roller 3 is cleaned off.

[0024] like Figure 1 and Figure 2 The exercise mechanism 2 shown is hinged to a connecting rod 10, the cleaning block 9 is fixed on the connecting rod 10, and the exercise mechanism 2 is provided with a return spring B11 that drives the cleaning block 9 to move toward the roller 3.

[0025] The roller 3 rotates on the cleaning block 9, and the cleaning block 9 is always in contact with the surface of the roller 3 under the action of the return spring B11 and the connecting rod 10.

[0026] like Figure 1 and Figure 2 The roller 3 shown has several cross-sections 301 extending along the axial direction of the roller 3 on its side. The cross-sections 301 are arranged around the axis of the roller 3 and have anti-slip textures.

[0027] The patient's limb rotates through the cut surface 301 and the roller 3 rotates.

[0028] In actual use, before using the exercise device 2, the patient's limb rotates the roller 3 clockwise through the cut surface 301. The cleaning block 5 and the cleaning tube 8 are always in contact with the surface of the roller 3 under the drive of the return spring A6. The roller 3 drives the cleaning tube 8 to rotate on the cleaning block 5, and the cleaning tube 8 rotates on the liquid absorption block 7. The liquid absorption block 7 transfers the disinfectant in the liquid storage tank 4 and sequentially absorbs it onto the surface of the cleaning tube 8. The disinfectant on the surface of the cleaning tube 8 sterilizes and disinfects the surface of the roller 3. At the same time, the disinfectant on the surface of the cleaning tube 8 is absorbed onto the surface of the roller 3. As the roller 3 rotates, the disinfectant on the surface of the roller 3 disinfects the limb parts of the patient that come into contact with the exercise device 2.

[0029] After the patient's limbs in contact with the exercise equipment 2 are disinfected, the patient's limbs rotate the roller 3 counterclockwise through the cut surface 301. The roller 3 rotates on the cleaning block 9. Under the action of the return spring B11 and the connecting rod 10, the cleaning block 9 is always in contact with the surface of the roller 3. The cleaning block 9 cleans the surface of the roller 3 in turn until the disinfectant attached to the surface of the roller 3 is cleaned.
