Description

Technical Field

[0001] This utility model relates to the technical field of rehabilitation training equipment, and in particular to a device for hand function rehabilitation after stroke. Background Technology

[0002] Stroke is an acute cerebrovascular disease caused by the sudden rupture or blockage of blood vessels in the brain, resulting in brain tissue damage. It is generally classified into two main categories: ischemic and hemorrhagic. Most patients experience varying degrees of loss of labor capacity or ability to live independently.

[0003] Stroke patients often experience insufficient hand grip strength, thus requiring grip rehabilitation training devices to train their hands. Current grip rehabilitation training devices have varying requirements for the tension of the finger sleeves depending on the patient's recovery stage. For example, in the initial recovery stage, hand grip strength is relatively weak, but with gradual rehabilitation training, hand grip strength gradually recovers and becomes stronger. However, existing devices usually require replacing elastic components with different elastic coefficients when adjusting the tension of the finger sleeves, which inevitably causes inconvenience. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a hand function rehabilitation device for stroke patients.

[0005] This utility model provides the following technical solution: a hand function rehabilitation device after stroke, comprising:

[0006] Mounting frame;

[0007] A training component, comprising several training components disposed on the mounting frame; the training components are used to train the patient's hand grasping ability;

[0008] The training components include:

[0009] Mounting base; the mounting base is located on the outside of the mounting frame;

[0010] A binding unit is disposed on the mounting base and is used to bind a patient's finger to the mounting base;

[0011] Elastic element; the elastic element is used to apply a force to the mounting base;

[0029] A device for hand function rehabilitation after stroke, such as Figures 1-3 The diagram shows: frame 13 and training component 2;

[0030] Among them, such as Figure 1As shown, the mounting frame 10 includes a base 11 and a frame 13 fixedly connected to the base 11. The frame 13 has a hollow structure inside and is open on both the front and back sides. The open sides of the frame 13 are detachably connected to side plates 12 by bolts. The base 11 is a non-slip base 11, which makes it easy to place the hand function rehabilitation device stably on the table. The upper wall of the frame 13 has five through holes 14 corresponding to the training component 2.

[0031] Training component 2 is used to train the patient's hand grasping ability; in this embodiment, five training components 2 are provided, and in other embodiments, they can be set as needed, such as ten, so that the patient's ten fingers can be trained at the same time;

[0032] like Figure 2 As shown, training component 2 includes: mounting base 21, binding unit 22, elastic element 24, and adjustment unit 25;

[0033] The mounting base 21 is located at the through hole 14 of the frame 13, and the width of the mounting base 21 is greater than the width of the through hole 14 to prevent the mounting base 21 from passing through the through hole 14. The binding unit 22 is set on the mounting base 21 and is used to bind the patient's finger to the mounting base 21. In this embodiment, the binding unit 22 consists of two Velcro straps, the ends of which are fixedly connected to the two sides of the mounting base 21 respectively. The patient's finger is restricted to the mounting base 21 by the free ends of the two Velcro straps fitting together. In other embodiments, the binding unit 22 can be a finger sleeve, and the patient's finger is directly inserted into the finger sleeve to restrict the finger to the mounting base 21. The elastic element 24 is used to apply force to the mounting base 21. Thus, after the patient inserts into the binding unit 22, when the patient performs grasping training, the elastic element 24 applies pressure to the patient's finger to achieve the training effect. The adjusting unit 25 is used to pull or release the elastic element 24 to adjust the elastic value of the elastic element 24.

[0034] In summary, the patient can place the back of their hand on the upper surface of the frame 13 and insert each finger into the binding unit 22. The binding unit 22 restricts the patient's fingers to the mounting base 21. The patient can then perform grasping training. When the patient's fingers clench, the binding unit 22 moves the mounting base 21. As the mounting base 21 moves, the elastic element 24 stretches, and the tension generated by the elastic element 24 applies pressure to the patient's fingers, thus achieving the training effect. As the patient's hand grip strength gradually recovers, the operator can operate the adjustment unit 25 to pull the elastic element 24, so that the elastic element 24 is initially in a stretched state. The greater the extension distance of the elastic element 24 pulled by the adjustment unit 25, the greater the force required for the patient's fingers to pull the elastic element 24 to extend it again, thereby adjusting the intensity of the patient's exercise. Conversely, the operator can also use the adjustment unit 25 to return the elastic element 24 to its original state, reducing the pressure applied to the patient's fingers.

[0035] Furthermore, a guide 23 is provided on the mounting base 21; the guide 23 passes through the through hole 14 and is detachably connected to one end of the elastic member 24; the other end of the elastic member 24 is detachably connected to the output end of the adjustment unit 25.

[0036] Specifically, a guide 23 is fixedly connected to the lower side of the mounting base 21. The width of the guide 23 is smaller than the width of the perforation 14, so that the patient's fingers will close when gripping. By setting the width of the guide 23 to be smaller than the width of the perforation 14, the patient's fingers can close. Of course, the guide 23 can be made of a soft, friction-resistant material. By making the guide 23 a soft material, the patient's fingers can fully close when gripping. By making the guide 23 have friction-resistant properties, the guide 23 moves at the perforation 14 for a long time, generating friction with the perforation 14, thus preventing damage to the guide 23. By detachably setting the elastic element 24 between the guide 23 and the adjustment unit 25, when the elastic element is damaged or needs to be replaced with an elastic element with a different elastic coefficient, the operator can remove the side plate 12 and then remove and replace the elastic element.

[0037] Furthermore, in this embodiment, the elastic member 24 includes an elastic band 241 and two hooks 242 provided at both ends of the elastic band 241. One hook 242 passes through the hanging hole on the guide member 23, and the other hook 242 passes through the hanging hole on the output end of the adjustment unit 25, thereby realizing the detachable connection of the elastic member 24; in other embodiments, the elastic member 24 may be a tension spring.

[0038] like Figure 3As shown, the adjustment unit 25 includes a sliding sleeve 251 fixedly connected to the mounting frame 10, a slider 252 slidably connected to the sliding sleeve 251, and a drive module for driving the slider 252 to move; the drive module includes a screw 253 rotatably connected to the mounting frame 10, a threaded sleeve 254 fixedly connected to the slider 252, and a drive component for driving the screw 253 to rotate, the screw 253 and the threaded sleeve 254 being threadedly connected; the drive component includes a transmission shaft 257 rotatably connected to the mounting frame 10, one end of the transmission shaft 257 passing through the side wall of the mounting frame 10 and protruding outside, and a bevel gear set 256 disposed between the screw 253 and the transmission shaft 257;

[0039] Specifically, the sliding sleeve 251 is fixedly connected to the inner bottom side of the frame 13, and the slider 252 is fitted inside the sliding sleeve 251 and can slide up and down within the sliding sleeve 251. One end of the screw 253 is rotatably connected to the inner bottom side of the frame 13, and the lower part of the slider 252 is fixedly connected to the threaded sleeve 254. The screw 253 and the threaded sleeve 254 are bolted together. By rotating the screw 253, the threaded sleeve 254 is driven to move up and down, and the up and down movement of the threaded sleeve 254 drives the slider 252 to move up and down. The hook 242 on one end of the elastic band 241 is connected to the hanging hole on the upper part of the slider 252, thereby allowing the slider 252 to move. The elastic band 241 is pulled to deform or reset; in order to prevent the above components from interfering with the external environment during operation, the above components are placed inside the frame 13; and to make it easier for the operator to drive the screw 253 to rotate, a drive unit is provided; the bevel gear set 256 of the drive unit consists of two bevel gears, one of which is fixedly connected to the transmission shaft 257, and the other bevel gear is fixedly connected to the screw 253, and the two bevel gears mesh with each other, so that the screw 253 can be rotated by rotating the transmission shaft 257 and transmitting power through the bevel gear set 256;

[0040] Furthermore, the drive module also includes a stabilizer 255 fixedly connected to the sliding sleeve 251, one end of the screw 253 being rotatably connected to the stabilizer 255, and the other end being rotatably connected to the mounting frame 10;

[0041] Specifically, the stabilizer 255 is fixedly connected to the upper part of the sliding sleeve 251, and thus the stabilizer 255 is also rotatably connected to the screw 253, which makes the screw 253 more stable when rotating.

[0042] Furthermore, the drive unit also includes a rotating seat 259 fixedly connected to the mounting frame 10, a drive shaft 257 rotatably connected to the rotating seat 259, and a knob 258 fixedly connected to the exposed end of the drive shaft 257;

[0043] Specifically, the rotating seat 259 is fixedly connected to the inner bottom side of the frame 13, and the drive shaft 257 passes through the rotating seat 259 and is rotatably connected to the rotating seat 259. The rotating seat 259 makes the rotation of the drive shaft 257 more stable. The knob 258 makes it easy for the operator to drive the drive shaft 257 to rotate.
