Description

A hand rehabilitation device for patients with hand spasm after stroke

technical field

The utility model belongs to the field of medical equipment, in particular to a hand rehabilitation device for patients with hand spasm after stroke.

Background technique

Post-stroke finger spasm is one of the most difficult problems encountered by stroke patients. Muscle spasticity is abnormal muscle tone characterized by speed-dependent stretch reflexes caused by increased spinal cord reflex activity after upper motor neuron injury, which seriously affects the motor function and activities of daily living of patients. The incidence of spasticity after stroke was estimated to be 19% and 38% at 3 months and over 1 year, respectively. In the later stage, the patient's hand often forms a flexed half-fist posture due to muscle spasm, which seriously affects the patient's life and work. At present, there are more and more devices for hand function rehabilitation on the market. Most of the current rehabilitation gloves or auxiliary devices help the spastic fingers to be straightened, which solves the technical problem that the fingers of hemiplegic patients are difficult to straighten in the prior art, but some devices only stretch the fingers, but cannot perform flexion and extension. Refers to exercise, the function is still relatively simple.

Patent 2014202244788 discloses a hand function rehabilitation training device, which is provided with an electric stimulation device that can control the treatment time and intensity on the glove body with a double-layer structure, wherein four pieces are arranged near the corresponding Baxie points on the inner layer Electrode pads for body surface stimulation, with an inflatable space between the inner and outer layers of the glove. The device can not only be driven by air pressure, but also can generate electrical stimulation to the hand acupoints. However, since the electrical stimulation device is fixed on the surface of the glove, it is impossible to find the acupoints correctly for patients with different hand sizes, which affects the therapeutic effect. It only acts on the four acupoints, and cannot achieve effective electrical stimulation of the hand acupoints.

Patent 2014205275805 discloses a neurorehabilitation training glove for hand joints, which includes a glove, a traction line and a buckle. The traction line is fixed at the tip of each finger on the palm of the glove, and the buckle is set on the fingers of the glove. The glove module is equipped with a controller, and then five electric telescopic rods are arranged on the controller, and the traction line passes through the buckle and is connected with the electric telescopic rods, so that the movements of clenching and opening the fingers are controlled by the controller. This device can exercise the hand function to a certain extent, but because it completely relies on mechanical force to complete the stimulation of the opponent, the therapeutic effect is relatively slow.

In order to make the whole device more concise, there are slots for accommodating electric wires around the outer shell. Wrap the wires connecting the electrode pads and the electrical stimulation device in the corresponding slots as required, and then adsorb the electrodes covered in the electrode protection sleeve on the surface of the shell.

The principle of the utility model: Baxie acupoints are called Dadu, Shangdu, Zhongdu, and Xiadu from the radial side to the ulnar side in "Miraculously Effective Prescriptions". Indications for dysphoria, eye pain, headache, stiff neck, sore throat, toothache, finger numbness, poisonous snake bites, red and swollen arms, etc. The standard acupoints are located on the dorsal side of the fingers, slightly clenched, between the first to fifth fingers, at the junction of the red and white flesh behind the edge of the finger web, a total of 8 acupoints on the left and right. There are skin, subcutaneous tissue and interosseous muscles under the point. The superficial branch of the radial nerve and the digital dorsal branch of the ulnar nerve are distributed, and the 8 acupoints correspond to the 1st-4th lumbrical muscles and the common digital palmar nerve. Acupuncture the Baxie acupoint firstly to relieve hand spasm, make the hand stretched and relaxed, and then alternately stimulate the palmar side flexors and wrist dorsiflexors to promote the patient to independently complete finger flexion and extension training, and then complete grasping and holding objects Function.

Beneficial effect: Compared with the prior art, the utility model relieves the flexor spasm of the hand by designing the longitudinal pulse electric stimulation between the palm and the finger, and at the same time through the corresponding interdigital dorsal extensor group and the forearm wrist extensor group on the back of the hand. Pulse electrical stimulation to promote the training of back extensor muscles. At the same time, on this basis, a high-frequency pulse current is simulated at the location of the Baxie point on the affected side to further stimulate the metacarpophalangeal joints to further assist the joint rehabilitation training of the fingers. On the other hand, by setting the electrode sheet in a semi-free form, it is convenient to accurately locate acupuncture points for different individuals, so that the personalized operation of the electric stimulation effect is stronger.
