Description

Hand function recovery grip strength trainer

Technical Field

The utility model relates to a device for assisting hand function recovery, carrying out the grip training to hand.

Background

Whether the direct injury to the hands or the stroke and the biased brain reduce the contraction control of the muscles, the obvious muscle weakness phenomenon of the fingers of the patient can occur. When a patient receives rehabilitation therapy, the patient is diagnosed by a doctor and then treated by a rehabilitation teacher with hands or by various instruments. The method comprises the step of guiding a patient to make periodic rehabilitation movement so as to induce the self-competence of the hand of the patient to recover.

At present, most hand rehabilitation instruments are complex and need to be trained in hospitals. Therefore, an appliance which is convenient for the patient to carry out rehabilitation training at any time is urgently needed.

SUMMERY OF THE UTILITY MODEL

To the technical problem that above-mentioned exists, the utility model provides a hand function resumes grip training ware can train the grip of patient's hand.

In order to solve the technical problem, the utility model discloses a technical scheme be a hand function resumes grip training ware, its characterized in that: the ball body is provided with a plurality of pits for fingers to grasp. The patient can hold the ball body in the palm and put the end part of the finger into the pit for grip training.

As an improvement, a measurement display device used for sensing and displaying the magnitude of the holding force value is arranged on the ball body. The device is used for sensing the pressure applied to the ball and feeding back the pressure.

As an improvement, the measurement display device comprises an induction cavity arranged inside the sphere and a sliding hole arranged on the sphere; one end of the sliding hole is connected with the induction cavity, and the other end of the sliding hole is communicated with the atmosphere; a sliding cylinder capable of sliding back and forth along the sliding hole is arranged in the sliding hole; an elastic air bag is arranged behind the sliding cylinder and communicated with the sensing cavity. When the patient presses the ball body, the sensing cavity is shrunk to extrude the gas into the air bag, so that the air bag is expanded. The expansion of the bladder pushes the shuttle from the rear to the front top. The pressure can be judged by the displacement of the slide cylinder.

As an improvement, a window is arranged on the sphere and is sealed by transparent materials, and the position of the window corresponds to the sliding hole. The movement of the sliding cylinder can be observed outside the sphere through the window, scales can be marked beside the window, and the sliding cylinder is used as a pointer to indicate the pressure.

As an improvement, a spring for resetting is arranged in front of the sliding barrel. After force is discharged, the sliding cylinder is reset to zero.

As an improvement, the ball body is made of rubber.

As a modification, the number of the pits is 5, which corresponds to the number of the fingers.

The utility model discloses an useful part lies in: the hand function recovery grip trainer with the structure can train the grip of the hand of a patient, and is beneficial to promoting the function recovery of the patient. The trainer realizes the training function by using a simple structure and can sense pressure and feed back, has low cost and low failure rate, does not need additional energy supply such as batteries and the like, and is economical, practical, convenient and applicable.

Drawings

Fig. 1 is a schematic view of the external structure of the present invention.

Fig. 2 is a schematic view of the internal structure of the present invention.

The labels in the figure are: 1 sphere, 2 pits, 3 induction cavities, 4 sliding holes, 5 sliding cylinders, 6 air bags, 7 springs and 8 windows.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the utility model comprises an elastic ball body 1, a plurality of pits 2 for fingers to grasp are arranged on the ball body 1. The ball body 1 is made of rubber. The number of the pits 2 is 5, and the pits correspond to fingers.

The sphere 1 is provided with a measuring and displaying device for sensing and displaying the holding force value. The measuring and displaying device comprises an induction cavity 3 arranged in the sphere 1 and a sliding hole 4 arranged on the sphere 1; one end of the sliding hole 4 is connected with the induction cavity 3, and the other end is communicated with the atmosphere; a sliding cylinder 5 capable of sliding back and forth along the sliding hole 4 is arranged in the sliding hole 4; an elastic air bag 6 is arranged behind the sliding cylinder 5, and the air bag 6 is communicated with the induction cavity 3. A spring 7 for resetting is arranged in front of the slide cylinder 5. The sphere 1 is provided with a window 8 and is sealed by transparent materials, and the position of the window 8 corresponds to the sliding hole 4.

In order to avoid the deformation of the sliding hole 4 when being pressed to influence the movement of the sliding cylinder 5, a transparent plastic pipe or a glass pipe can be arranged in the sliding hole 4, so that the sliding cylinder 5 slides in the pipe. And the opening of the air bag 6 shields the channel between the sensing cavity 3 and the slide hole 4, so as to avoid air leakage.

When in use, a patient holds the whole ball body 1 in the palm and puts the ends of the fingers in the concave pits 2 to apply holding force to the ball body 1. Under the action of pressure, the sensing cavity 3 deforms to extrude air in the sensing cavity to the air bag 6, so that the air bag expands to push the sliding cylinder 5 forwards. The slide cylinder 5 can be used as a pointer to indicate the magnitude of the pressure.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
