Description

The pulse-magnetotherapeutic appearance

Technical field

This utility model relates to the armarium technical field, is specifically related to a kind of pulse-magnetotherapeutic appearance.

Background technology

Stroke patient performance the following aspects: the one, cerebrovascular causes that because of hemorrhage or thrombosis, thromboembolism disturbance of blood circulation, nervous tissue are impaired; Seriously cause paraplegia, the 2nd, sequela stage is because of disease is controlled the not good patient of causing spirit for a long time, psychology is out of control, like irritability, irritability, stubbornness, depressed, insomnia or drowsiness, things gone ape etc.

The urbanite lacks an amount of motion, is sitting in for a long time to face toward computer work in the office, and accumulating over a long period has slowly become sore spot.The sick main performance in this city: bow for a long time and bend over one's desk working, make vertebra and the intervertebral disc of vertebra time outstanding backward, compressing spinal cord or blood vessel; Or require to keep for a long time same posture, and finally cause having a stiff neck, muscular strain, influence the cervical vertebra diseases activity, be easy to generate hyperosteogeny: with advancing age, intervertebral disc dehydration dwindles, the stability decreases of cervical vertebra; Like at ordinary times sleeping soft bed, rest the head on high medicated pillow.High medicated pillow, soft bed or sofa can the labour contractor push away forward, make cervical vertebra preceding bent, pull the ligament at cervical vertebra rear easily, perhaps are exactly to force intervertebral disc outstanding backward, the spinal cord and the blood vessel at compressing cervical vertebra rear portion.The sickness rate of cervical spondylosis in the white collar of city is increasingly high now, has reached 25% of afflicted, becomes the crowd of the main force of cervical spondylosis just gradually.

Due to scapulohumeral periarthritis is affected by the cold by shoulder, again because of ill metathorax shoulder joint is stiff, limitation of activity; Like having freezed, belong to the chronic inflammatory disease of soft tissues such as all muscle of shoulder, flesh chamber, synovial bursa and joint capsule, during morbidity; Even night, sleep also can be ached, even can be awake bitterly at midnight.

The sick chronic disease that belongs to such as above-mentioned senile apoplexy, neck, lumbar spondylosis and scapulohumeral periarthritis; It is human now commonly encountered diseases; Because the traditional Drug therapy of the particularity of above-mentioned disease can't arrive brain cell, vertebral pulp through blood, so general medicine is to be difficult to arrive the affected part, also is the insoluble always difficult problem of medical circle at all; So cervical and lumbar diseases is called not dead cancer of 21 century; The untimely treatment of cervical spondylosis can constantly increase the weight of disease well with age, shoulder arm numbness, pain occur, gently then causes people's dizziness, feeling of fullness in the head, heavy then confused glue, paraplegia.

Summary of the invention
