Description

A passive grip ball

technical field

The invention belongs to the technical field of medical devices, in particular to a passive grip ball.

Background technique

Grip ball, with high elasticity, can exercise strong palm muscles, flexibility, strength and perception of fingers, can be suitable for rehabilitation people, etc., exercise fingers, arm strength, the size of the grip ball is not large, just in the palm of the hand, Grip the power ball, squeeze it hard, you can feel the pressure brought by the grip ball to the fingers. Generally, if you hold the power ball for N times, you can feel the palm of your hand feel numb and hot, because when you squeeze the power ball hard, the flexible sphere deforms and fills the palm of your hand. Tighten and loosen, the ball can effectively stimulate the major acupoints of the palm, promote blood circulation, and improve the recovery speed of the patient.

Rehabilitation requires that patients use the grip ball to meet the specified action standards, specified time and specified intensity requirements. However, some patients have relatively small hand strength and cannot meet the standard of standard gripping balls. The effect is very small, and some patients do not. Able to use the grip ball correctly (such as continuous grip time and inaccurate strength), so it is difficult to use the grip ball for effective exercise, thus failing to achieve a good recovery effect, resulting in the lifeline of hemodialysis patients - arteriovenous fistula mature. Hemodialysis patients are forced to choose long-term catheters dedicated to hemodialysis. Long-term catheters are most commonly inserted into the internal jugular vein, which is extremely inconvenient for patients’ personal hygiene such as bathing. Originally, dialysis patients were weak, which could easily lead to catheter infection and even life-threatening. The patients had to be hospitalized for anti-inflammatory and other treatments. Those with poor results had to be extubated and re-intubated, which not only increased the patient's pain, but also had to bear expensive economic burdens, and even Therefore, it is impossible to support the follow-up treatment, and the life is worrying; the image of the patient's long-term intubation is damaged, resulting in a sense of stigma, affecting daily work and life, leading to varying degrees of negative psychology, and even self-mutilation and suicide; some patients with long-term catheter intubation may experience redness and swelling Discomfort such as itching, as well as micro-inflammatory state, will affect the quality of life and life safety of patients. Therefore, a passive grip ball that can be accurately adjusted according to the patient's state and needs can be used for hemodialysis patients' internal fistula maturation and functional exercise of vascular access Sexual maintenance plays a very important role, but the current grip balls on the market require patients with a certain grip strength to take the initiative to hold the ball, and the maintenance of internal fistulas is limited to hot compresses. There are rehabilitation gloves for hemiplegic patients with empty-hand grip/expansion, which have not been found yet. It is suitable for vascular access function exercise and maintenance of hemodialysis patients, and has similar functions to the product of the present invention.
