Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and in particular to a patient's hand nerve-assisted rehabilitation training system. Background Art

[0002] The hand functions are relatively delicate. If the hand nerves are damaged, joint stiffness, scar contracture, functional impairment, etc. are likely to occur. Currently, the commonly used hand function rehabilitation methods in clinical practice are mainly divided into physical rehabilitation training, sensory recovery training, motor recovery training, and occupational training.

[0003] 1. Physical rehabilitation training: Physical therapy is the use of physical factors produced by physical therapy instruments, such as electricity, magnetism, light, sound, heat, etc., to act on the diseased body, causing a series of biological effects in the body, thereby achieving a certain purpose of preventing and treating diseases. Commonly used clinical methods include direct current therapy, audio therapy, infrared therapy, etc., which require treatment in the rehabilitation department of the hospital. At the same time, hot compresses can also be used for rehabilitation treatment in life; 2. Sensory recovery training: When the hand nerves are damaged, the sensory function of the hand will also be damaged. For people who have a certain sense of touch but are not sensitive, small objects of various shapes and textures, such as keys, pins, etc., can be placed in a container, and picked up blindly with eyes closed, and then picked up with eyes open, so as to repeatedly strengthen the nerve function of the hand. For people with abnormal sensation in their hands, you can put cotton balls, beans and other materials of different textures in a small bucket and stir them with your hands. You can also use objects of various shapes and sizes for grip training, such as grasping a water cup, a grip ball, etc.; 3. Sports recovery training: Sports recovery training is mainly used to restore joint mobility and muscle strength. The main way to train joint mobility is to move. Appropriate grip training can be performed without affecting the hand wound. If you cannot or dare not do active activities, you can use a continuous passive activity device for auxiliary exercise; 4. Occupational training: Occupational training is a practical functional therapy. You can choose training methods according to the patient's living and working environment, such as dressing and undressing, knitting, painting, etc.

[0004] In the exercise recovery training, patients generally use a hand gripper to assist in grip training. During the use of the hand gripper, the patient applies grip strength with the help of a doctor, and the grip rebounds through a spring or other rebound mechanism to achieve the training effect. However, this grip training method cannot achieve the patient's autonomous control of grip resistance, and greatly increases the doctor's labor intensity, making it difficult to achieve a good training effect. To this end, we proposed a patient hand nerve-assisted rehabilitation training system. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a patient hand nerve-assisted rehabilitation training system.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A patient hand nerve-assisted rehabilitation training system comprises a palm sleeve, a gripping mechanism and a driving mechanism, wherein the output end of the driving mechanism is connected to the gripping mechanism, and the driving mechanism is pivotally connected to the gripping mechanism;

[0008] The driving mechanism comprises an electric push rod 1 and an electric push rod 2, wherein the output end of the electric push rod 1 is connected to the front finger palm clamp, and the output end of the electric push rod 2 is connected to the rear finger palm clamp;

[0009] The rear finger palm clamp is arranged on the front side of the palm cover and fits the shape of the five fingers of a human hand;

[0010] The electric push rod 1 and the electric push rod 2 respectively fix the front and back sides of the patient's fingers through the front finger palm clamp and the back finger palm clamp, and change the grip resistance through stretching while fixing.

[0011] Preferably, a finger pad is provided at the connection between the palm cover and the rear finger-palm clamp, and an inner finger groove is provided on the inner side of the connection between the palm cover and the rear finger-palm clamp through the finger pad.

[0012] Preferably, a mounting seat 1 is fixedly mounted on the middle of the upper surface of the front end of the palm cover, a rotating plate is hinged on the mounting seat 1, and the electric push rod 1 is mounted on the front end of the rotating plate away from the hinge.

[0013] Preferably, a swing rod is rotatably mounted on the output end of the electric push rod 1, and connecting rod 1 is hinged at both ends of the swing rod, and one end of the connecting rod 1 away from the swing rod is hinged to the front finger palm clamp.

[0014] Preferably, a driving rod is installed at the output end of the second electric push rod, and an end of the driving rod away from the second electric push rod is connected to a swivel, and the swivel is sleeved on the middle part of the pin shaft on the first mounting seat.

[0015] Preferably, a connecting plate is installed at the rear end of the rotating plate, and both ends of the front side of the connecting plate are hinged to the rear finger-palm clamp through a connecting rod mechanism that is the same as the connecting rod 1.

[0016] Preferably, a second mounting seat is provided in the middle of the upper end of the front finger palm clamp, and the first connecting rod is hinged to the front finger palm clamp through the second mounting seat.

[0017] Preferably, a pull rod is laterally installed at one end of the second electric push rod away from the driving rod, and the pull rod is used to pull the second electric push rod.

[0018] The invention provides a patient hand nerve assisted rehabilitation training system, which has the following beneficial effects:

[0019] 1. When using the training system, the patient inserts the index finger and the middle finger of one hand into the corresponding posterior palm clamp and front palm clamp of the connecting rod 1 in turn according to the shape of the palm sleeve, and the finger grooves between the fingers are located in the inner finger grooves, and a close fit is achieved; then the other hand holds the pull rod, and the electric push rod 1 and the electric push rod 2 are respectively started, so that the posterior palm clamp and the front palm clamp are bent under the action of the electric push rod 1 and the electric push rod 2 and the connecting rod 1, thereby enabling the patient to grasp without the assistance of the doctor, and can independently control the grasping strength, and make self-adjustments according to the recovery of the grasping ability, which is convenient for use and reduces the labor intensity of the doctor;

[0020] 2. By setting up the palm cover and the inner finger groove, the sweat of the patient's hands can be quickly absorbed, avoiding the sweat of the hands affecting the smooth progress of the grasping training during the grasping training. And because the grasping of the human hand is mainly achieved under the grasping action of the index finger and the middle finger, it can save manufacturing costs, improve the efficiency of the patient's hand rehabilitation training, and is conducive to promotion.

[0036] The electric push rod 1 9 and the electric push rod 2 18 respectively fix the front and back sides of the patient's fingers through the front finger palm clamp 12 and the back finger palm clamp 4, and change the grip resistance through stretching while fixing.

[0037] During use: according to the shape of the palm sleeve 1, the patient sequentially inserts the index finger and the middle finger of one hand into the rear finger palm clamp 4 and the front finger palm clamp 12 corresponding to the connecting rod 11, and the finger grooves between the fingers are located in the inner finger groove 6, and a tight fit is achieved; then the other hand holds the pull rod 17, and the electric push rod 1 9 and the electric push rod 2 18 are respectively started, so that the rear finger palm clamp 4 and the front finger palm clamp 12 are bent under the action of the electric push rod 1 9 and the electric push rod 2 18 and the connecting rod 1 11, thereby enabling the patient to grasp without the assistance of a doctor, and can independently control the grasping strength and make self-adjustments according to the recovery of his own grasping ability, which is convenient for use and reduces the labor intensity of the doctor.

[0038] As a technical optimization solution of the present invention, a finger pad 5 is provided at the connection between the palm cover 1 and the rear finger and palm clip 4, and an inner finger groove 6 is provided on the inner side of the connection between the palm cover 1 and the rear finger and palm clip 4 through the finger pad 5.

[0039] By providing the palm cover 1 and the inner finger groove 4, sweat on the patient's hands can be quickly absorbed, thus preventing sweat on the hands from affecting the smooth progress of the grip training during the grip training.

[0040] As a technical optimization solution of the present invention, a mounting seat 7 is fixedly installed in the middle of the upper surface of the front end of the palm cover 1, a rotating plate 8 is hinged on the mounting seat 7, and an electric push rod 9 is installed on the front end of the rotating plate 8 away from the hinge.

[0041] The electric push rod 9 is arranged on the rotating plate 8, so that the front palm clamp 12 of the patient's finger can be bent during the rotation of the electric push rod 9, thereby providing a certain gripping force obstacle to the finger.

[0042] As a technical optimization solution of the present invention, a swing rod 10 is rotatably installed at the output end of the electric push rod 9, and both ends of the swing rod 10 are hinged with a connecting rod 11, and the end of the connecting rod 11 away from the swing rod 10 is hinged to the front finger palm clamp 12.
