Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an elbow joint auxiliary exercise rehabilitation device. Background Art

[0002] The elbow joint is composed of the lower end of the humerus and the upper ends of the ulna and radius. It includes three joints, namely the humero-ulnar joint, the humeroradial joint and the proximal radioulnar joint. It can perform flexion and extension movements, and also participates in the pronation and supination movements of the forearm. Patients need rehabilitation training after surgery or injury to the elbow joint. At this time, they need to use elbow joint assisted motion rehabilitation devices.

[0003] For example, an existing patent (publication number: CN218420353U) discloses an elbow joint exercise device for physical therapy and rehabilitation, which fixes the arm by using an upper arm fixing strap and a forearm fixing strap. It has a simple structure and good fixing effect. It can be applied to the arms of different patients and has strong versatility.

[0004] However, the above-mentioned physical therapy and rehabilitation elbow joint exercise device still has some shortcomings in actual application: although the physical therapy and rehabilitation elbow joint exercise device can achieve the effect of fixing the arm by relying on the upper arm fixing strap, Velcro sub-stick and Velcro mother sticky structure, but because the fixing straps are distributed on both sides, it is more troublesome to wear in practice, and it is inconvenient for the patient to stack the two fixing straps together and stick them together, thereby reducing the use effect.

[0005] To this end, we designed an elbow joint assisted motion rehabilitation device to solve the above problems. Utility Model Content

[0024] A cavity 13 and a sliding opening 14 are respectively provided inside and on the top of the positioning frame 4. The limiting shaft 5 is rotatably connected in the cavity 13. The two ends of the return spring 8 are respectively fixedly connected to the inner wall of the cavity 13 and the positioning rack 9. The two ends of the second spring 18 are respectively fixedly connected to the limiting belt 3 and the inner wall of the cavity 13. One end of the limiting belt 3 is slidably inserted in the sliding opening 14.

[0025] During the specific implementation, the patient's upper limb to be rehabilitated is first passed through the limiting belt 3 and placed on the top of the positioning plate 1. During this process, the limiting belt 3 can be pulled and rotated and extended on the limiting shaft 5. After the patient's upper limb is passed through the limiting belt 3, the torsion block 11 is then rotated to make the torsion block 11 drive the threaded rod 10 to rotate and move downward, pushing the positioning rack 9 to move downward and engage with the positioning gear 7. During this process, the reset spring 8 will be stretched, and the limiting shaft 5 can be positioned, thereby achieving the effect of quickly wearing the positioning plate 1.

[0029] Depend on Figure 1-3An elbow joint auxiliary exercise rehabilitation device is given, including a positioning plate 1, a rotating plate 2 is rotatably provided on one side of the top of the positioning plate 1, and two limit assemblies are provided on the positioning plate 1, and the limit assemblies are used to wear the positioning plate 1 on the patient's upper limb, and the limit assemblies include a limiting belt 3, a positioning frame 4, a limiting shaft 5, a positioning gear 7, a reset spring 8, a positioning rack 9, a threaded rod 10, a torsion block 11 and a second spring 18, the limiting belt 3 is set on the top of the positioning plate 1, the positioning frame 4 is set on the positioning plate 1, and the limiting shaft 5 is rotatably set in the positioning frame 4, the limiting belt 3 is wrapped around the limiting shaft 5 and the end away from the positioning plate 1 is fixedly connected to the limiting shaft 5, the positioning gear 7 is fixedly sleeved on the limiting shaft 5, and the reset spring The spring 8 is arranged in the positioning frame 4 and the other end is fixedly connected to the positioning rack 9, the positioning rack 9 is meshed with the positioning gear 7, the threaded rod 10 is threadedly inserted into one side of the positioning frame 4 and one end is against the positioning rack 9, the torsion block 11 is arranged at the other end of the threaded rod 10, the second spring 18 is movably sleeved on the limit shaft 5 and the two ends are respectively connected to the limit belt 3 and the positioning frame 4, two mounting seats 15 are symmetrically provided on the top of the positioning plate 1, and a pin 16 is fixedly provided on the opposite side of the two mounting seats 15, the rotating plate 2 is rotatably sleeved on the pin 16, and two first springs 17 are symmetrically and movably sleeved on the pin 16, and the two ends of the first spring 17 are respectively fixedly connected to the mounting seat 15 and the rotating plate 2.

[0030] In specific implementation, based on the first embodiment, the patient bends his elbow so that the rotating plate 2 rotates around the mounting seat 15 and twists the first spring 17, thereby overcoming the elastic force of the first spring 17 to achieve the training effect, which is conducive to accelerating the patient's recovery.

[0031] The positioning plate 1 is provided with a plurality of ventilation holes 6. By providing the ventilation holes 6, the user can avoid sweating on the arm when using the elbow joint auxiliary exercise rehabilitation device for a long time and being unable to discharge the sweat in time, thereby improving the comfort.

[0032] The twist block 11 is provided with anti-skid lines. By providing the anti-skid lines on the twist block 11, the friction between the hand of the operator and the twist block 11 can be increased, thereby helping to solve the problem of slipping when the operator rotates the twist block 11.

[0033] Working principle:

[0034] When in use, first pass the patient's upper limb to be rehabilitated through the limiting belt 3 and place it on the top of the positioning plate 1. During this process, the limiting belt 3 can be pulled and rotated and extended on the limiting shaft 5. After the patient's upper limb passes through the limiting belt 3, the torsion block 11 is then rotated to make the torsion block 11 drive the threaded rod 10 to rotate and move downward, pushing the positioning rack 9 to move downward and engage with the positioning gear 7. During this process, the return spring 8 will be stretched, and the piston end of the piston rod 12 will be extended accordingly, positioning the limiting shaft 5, and the effect of quickly wearing the positioning plate 1 can be achieved. This operation can be performed by the patient with one hand, which is relatively convenient. Then the patient bends his elbow, causing the rotating plate 2 to rotate around the mounting seat 15 and twist the first spring 17, so as to overcome the elastic force of the first spring 17 to achieve the training effect, which is conducive to accelerating the patient's recovery.
