Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a hand rehabilitation training device. Background Art

[0002] Hemiplegia, also known as hemiplegia, is the complete paralysis of half of the body. It refers to central nervous system damage caused by various reasons, resulting in paralysis of one limb (upper or lower limb), often accompanied by ipsilateral cranial nerve damage, and is more common in intracranial lesions or stroke. Hemiplegic patients need to undergo rehabilitation training to maintain joint mobility, prevent joint stiffness, adhesion and atrophy, promote blood circulation, facilitate the supply of joint nutrition, restore joint function, and stimulate nerves through feedback from training activities, thereby improving the recovery of hemiplegic patients. However, the existing hand rehabilitation training structure is usually exercised by controlling the hand as a whole to grasp, such as a hand rehabilitation trainer released by CN219072003, which does not involve fine movements of the fingers, which results in fewer muscles and nerves involved when it drives the hand to move, and the effect of promoting blood circulation or performing nerve feedback stimulation is poor, such as difficulty in performing finger exercises, so it needs to be improved. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a hand rehabilitation training device.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A hand rehabilitation training device comprises a placement plate, wherein the left and right sides of the placement plate are rotatably connected with a left bracket and a right bracket via a rotating shaft; the rotating shaft on the right side of the placement plate is connected with a reciprocating rotating mechanism, characterized in that a glove is installed on the placement plate, the back of the hand corresponding to the palm of the glove is fixedly connected to the placement plate, and the remaining parts are separately arranged from the placement plate; spring pieces which are bent or curled in a natural state are respectively fixed at the back of the glove corresponding to the fingers, and an airbag is respectively arranged at the front side of the glove corresponding to each finger joint, the airbag spans the finger joint and becomes straight after being inflated; the airbags are respectively connected with a main airway via bronchi, the main airway is connected with an inflation device, a three-way solenoid valve is installed on the bronchus, one end of the three-way solenoid valve is connected with the atmosphere, and the three-way solenoid valve is communicatively connected with a solenoid valve controller.

[0006] As a further improvement, the reciprocating rotating mechanism includes a reciprocating rotating motor, and the reciprocating rotating motor is connected to the rotating shaft through a reducer.

[0007] As a further improvement, the inflation device is an air pump.

[0009] As a further improvement, feet are installed at the bottom of the left bracket and the bottom of the right bracket.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model can realize the individual control of each joint of the finger, so that the patient's fingers can passively make different complex movements, and even connect finger exercises, which can involve more muscles of the hand and form good feedback stimulation to the nerve center.

[0012] 2. It can realize the coordinated movement of fingers and wrists. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described with reference to the accompanying drawings, but the contents in the accompanying drawings do not constitute any limitation to the present invention.

[0014] Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0015] Figure 2 Schematic diagram of the top view of the glove. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and examples.

[0017] Example 1

[0018] like Figure 1 and Figure 2 A hand rehabilitation training device shown includes a placement plate 1, a rotating shaft 2, a reciprocating rotating mechanism 3, a reciprocating rotating motor 31, a reducer 32, a glove 4, a shrapnel 5, an airbag 6, a bronchus 7, a main air pipe 8, an inflating device 9, a three-way solenoid valve 10, a foot pad 11, a left bracket 12 and a right bracket 13.

[0019] Among them, the placement plate 1 rotates through the rotating shaft 2; it is connected to the left bracket 12 and the right bracket 13, and the placement plate 1 is fixed with a glove 4, and only the back position corresponding to the palm of the glove 4 is fixed. The front of the glove 4 is respectively provided with an airbag 6 corresponding to each finger joint, and the airbag 6 spans the finger joint and becomes straight after being inflated. The airbag 6 is connected to the main air pipe 8 through the bronchus 7, and the main air pipe 8 is connected to the inflation device 9. A three-way solenoid valve 10 is installed on the bronchus 7, and one end of the three-way solenoid valve 10 is connected to the atmosphere. The three-way solenoid valve 10 is connected to the solenoid valve controller, and the back of the glove 4 is respectively fixed with a spring 5 in a natural state of bending or curling at the corresponding fingers.

[0020] In this way, when the airbag 6 is not inflated, the finger part will be curled under the action of the spring piece 5.

[0021] The method of use is as follows: first, all the airbags 6 are inflated to unfold the glove 4, and then the patient's hand is inserted into the glove 4, and then different three-way solenoid valves 10 are controlled to deflate respectively to deflate the corresponding airbags 6, so that the corresponding finger joints will bend under the action of the shrapnel, while the finger joints corresponding to the airbags that have not been deflated are still straight. In this way, the inflation and deflation of different airbags are controlled to make each finger joint perform different movements, rather than straightening or curling as a whole, so that the patient's palm can perform different movements and even do finger exercises, overcoming the problem that the finger joints perform curling or straightening movements at the same time, resulting in a small number of stretched muscles, a small stretching force, and a poor effect of promoting blood circulation. At the same time, neural feedback is performed by controlling each finger to perform different movements, which is beneficial to the recovery and reconstruction of the patient's nerves.

[0022] While the above control is being performed, the reciprocating rotation mechanism 3 can simultaneously perform reciprocating rotation, thereby causing the palm of the person to rotate and perform wrist movements.

[0023] The inflation device 9 is an air pump. The spring sheet 5 is preferably a stainless steel sheet.

[0024] In order to maintain stability, feet 11 are installed at the bottom of the left bracket 12 and the right bracket 13.

[0025] The device can be provided one for the left hand and one for the right hand respectively, so that the left hand and the right hand can be exercised at the same time.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
