Rehabilitation device for impaired flexion and extension functions of arm muscle group and wrist muscle group

Abstract

The invention relates to a rehabilitation device, in particular to a rehabilitation device for impaired flexion and extension functions of an arm muscle group and a wrist muscle group. The invention provides the rehabilitation device for impaired flexion and extension functions of an arm muscle group and a wrist muscle group, which is low in cost, is convenient for patients with muscle group impairment to autonomously and effectively train, and can relieve the aching feeling of arms. The rehabilitation device for impaired flexion and extension functions of an arm muscle group and a wrist muscle group comprises a bottom frame and a seat, and the seat is arranged on the bottom frame, the height adjusting mechanism is arranged on the bottom frame, and the elbow movement mechanism is arrangedon the height adjusting mechanism. By arranging the height adjusting mechanism, the heights of the height adjusting mechanism and the elbow movement mechanism can be adjusted according to the length of the arm of a patient, the second rotating shaft is driven to rotate through arm strength, the second rotating shaft drives the second disc to rotate along with the first rotating shaft, and therefore the elbow movement effect can be achieved.

Description

technical field

[0001] The invention relates to a rehabilitation device, in particular to a rehabilitation device with impaired flexion and extension functions of arm muscles and wrist muscles. Background technique

[0002] People adopt incorrect exercise postures and inappropriate exercise methods when exercising, resulting in easy damage and strain of upper arm muscles and joints. As a result, more and more patients have impaired flexion and extension functions of arm muscles and wrist muscles. There are relatively few researches on group functional training and strength rehabilitation devices, and the technology is relatively immature.

[0003] Patent application CN209004593U, publication number 20190621, discloses a rehabilitation device for impaired flexion and extension functions of arm muscles and wrist muscles, including a base, a wrist rehabilitation device and an arm rehabilitation device. etc. On the one hand, it protects the safety of the rehabilitators well and...

Embodiment 1

[0067] A rehabilitation device for impaired flexion and extension functions of arm muscles and wrist muscles, such as figure 1 As shown, it includes an underframe 1, a seat 2, a height adjustment mechanism 3 and an elbow movement mechanism 4. The upper and rear sides of the underframe 1 are provided with a seat 2, and the upper and front sides of the underframe 1 are provided with a height adjustment mechanism 3. The adjustment mechanism 3 is provided with an elbow movement mechanism 4 .

[0068]When the flexion and extension functions of the arm muscles and wrist muscles are impaired, this rehabilitation device can be used. First, the patient sits on the seat 2, and then adjusts the height of the height adjustment mechanism 3 so that the hand can be placed on the elbow movement mechanism 4. Then turn the elbow movement mechanism 4 by arm strength, the elbow movement mechanism 4 drives the height adjustment mechanism 3 to rotate, and the arm and wrist move back and forth to ac...

Embodiment 2

[0070] On the basis of Example 1, such as figure 2 and image 3 As shown, the height adjustment mechanism 3 includes a first fixed frame 31, a first connecting rod 32, a bolt 33, a first rotating shaft 34 and a first disk 35, and the first fixed frame 31 is symmetrically arranged in the middle of the front side of the chassis 1. , the upper part of the first fixed frame 31 on the right side is fixedly connected with the first connecting rod 32 through the bolt 33, the rear side of the first connecting rod 32 is rotatably provided with the first rotating shaft 34, and the left side of the first rotating shaft 34 is provided with the first disc 35.

[0071] Manually loosen the nuts on the bolts 33, the bolts 33 drive the first connecting rod 32 to swing up and down, and the first connecting rod 32 drives the first rotating shaft 34 and the first disc 35 to move together with the elbow movement mechanism 4, so that the patient can Put your hand on the elbow movement mechanism ...

Embodiment 3

[0075] On the basis of Example 2, such as Figure 4-7 As shown, a driving mechanism 5 is also included, and the driving mechanism 5 includes a third rotating shaft 51, a third disc 52, a fourth disc 53, a fourth rotating shaft 54, a pedal 55 and a first transmission assembly 56, two second A third rotating shaft 51 is rotatably connected between the top of a fixed frame 31, the third rotating shaft 51 middle part is provided with a third disk 52, the third disk 52 left and right sides are all provided with a fourth disk 53, the fourth disk 53 The eccentric position rotation type is provided with a fourth rotating shaft 54 ​​, a pedal 55 is arranged outside the fourth rotating shaft 54 ​​, and a first transmission assembly 56 is connected between the third rotating shaft 51 and the first rotating shaft 34 .

[0076] Some severe patients have almost weak hands, so they cannot rotate the first rotating shaft 34 through arm strength. The patient can put both feet on the pedal 55, ...
