Description

Novel finger rehabilitation training device for children

Technical Field

The invention relates to a finger rehabilitation instrument, in particular to a novel finger rehabilitation training device for children.

Background

After the fingers are seriously mechanically injured, the symptoms of flexion deformity are easy to appear, which mainly show that the superficial flexor muscles are shortened, skin is often shortened, and the function of extending the fingers is limited to a certain extent. At present, when the disease is treated, a mechanical correction mode is mainly adopted, namely, the flexion and extension of the fingers are guided by the aid of an appliance, and the muscles of the fingers are properly exercised with certain resistance. However, the existing appliance is a simple finger-clamping plate with a flexion-extension function, and the appliance has poor correction effect when performing rehabilitation training on the fingers. In order to achieve effective confrontational training, the prior art often carries out confrontational training through a counterweight type trainer. However, the traditional counterweight type rehabilitation training device has a relatively stiff counteracting force curve in the using process, is easy to cause 2 times of damage to fingers when the counteracting load is relatively large, is not suitable for patients in the early stage of rehabilitation,

disclosure of Invention

In order to solve the problems in the prior art, the invention provides a novel child finger rehabilitation training device which is good in rehabilitation effect and not easy to hurt.

The technical scheme adopted by the invention is as follows: a novel finger rehabilitation training device for children comprises a chassis, a support frame and four groups of confrontation components which are arranged on the support frame side by side;

the support frame comprises two vertical rods which are parallel to each other, an upper cross rod and a lower cross rod are arranged between the upper part and the lower part of the two vertical rods, and two ends of the upper cross rod and the lower cross rod are fixedly connected with the vertical rods respectively; a transverse shaft is arranged between the top ends of the vertical rods;

the confrontation assembly comprises a confrontation spring arranged between the upper cross rod and the lower cross rod, the lower end of the confrontation spring is connected with the lower cross rod, the upper end of the confrontation spring is connected with the lower end of the pull wire, and the upper end of the pull wire penetrates through a guide hole on the upper cross rod and is connected with the ring after bypassing a guide wheel arranged on the cross shaft.

Preferably, an adjusting bolt is further arranged below the counter spring, penetrates through a threaded hole in the lower cross rod and is in threaded fit with the lower cross rod; the upper end of the adjusting bolt is connected with the lower end of the counter spring through a rotary joint.

Preferably, the chassis comprises an upper strip plate and a lower strip plate which are arranged side by side, wherein a plurality of groups of bolt holes are correspondingly arranged on the upper strip plate and the lower strip plate and are matched with locking bolts and locking nuts; the upper lath and the lower lath are locked by a locking bolt and a locking nut and clamped on the base body.

Preferably, the bottom of the adjusting bolt is provided with an inverted Y-shaped plastic screwing piece.

The invention has the beneficial effects that: the auxiliary training can be performed on the finger bending and stretching actions, the recovery of hand muscles and the shape modeling are facilitated, and the safety is high. Specifically, in the use process, after the finger ring is installed and fixed, the finger is arranged in the finger ring in a penetrating mode. And bending the finger, wherein the finger pulls the counter spring through the pull wire in the bending process. The resisting spring generates enough resistance to resist in the process of bending and stretching the fingers, so that the exercise effect is improved, and the rapid recovery and shaping of the muscle form of the fingers are facilitated. In addition, as the counter spring is adopted as the counter source, compared with the traditional scheme of taking the counter weight as the counter source, the counter force of the training device has a better extinction curve, is not easy to cause secondary damage in the training process, and has excellent safety.

Detailed Description

As the traditional counterweight type rehabilitation training device has a relatively stiff reduction curve of the counterforce in the use process, easily causes 2-time damage to fingers when the counterforce is large, and is not suitable for being used by patients in the early stage of rehabilitation, the invention provides a novel child finger rehabilitation training device which comprises a chassis, a support frame and four groups of counterforce components arranged on the support frame side by side, as shown in figure 1-2.

The support frame comprises two vertical rods 16 which are parallel to each other, an upper cross rod 17 and a lower cross rod 18 are arranged between the upper portion and the lower portion of each vertical rod 16, and two ends of each upper cross rod 17 and two ends of each lower cross rod 18 are fixedly connected with the corresponding vertical rods 16 respectively. A transverse shaft 19 is arranged between the top ends of the upright rods 16. The resisting assembly comprises a resisting spring 20 arranged between an upper cross bar 17 and a lower cross bar 18, the lower end of the resisting spring 20 is connected with the lower cross bar 18, the upper end of the resisting spring 20 is connected with the lower end of a pull wire 21, and the upper end of the pull wire 21 passes through a guide hole on the upper cross bar 17 and is connected with a finger ring 23 after bypassing a guide wheel 22 arranged on a transverse shaft 19.

During the bending process of the finger, the pull wire 21 pulls the counter spring 20. The resisting spring 20 generates enough resistance force to resist during the process of bending and stretching the fingers, thereby improving the exercise effect and facilitating the rapid recovery and shaping of the muscle form of the fingers. In addition, as the counter spring 20 is adopted as a counter source, compared with the traditional scheme of taking a counter weight as a counter source, the counter force of the training device has a better extinction curve, is not easy to cause secondary damage in the training process, and has excellent safety.

Since different patients have larger difference in the magnitude of the counter force during the counter training, in order to improve the versatility of the present invention, it is better to further arrange an adjusting bolt 24 below the counter spring 20, wherein the adjusting bolt 24 is inserted into a threaded hole on the bottom rail 18 and forms a threaded fit with the bottom rail 18. The upper end of said adjusting bolt 24 is connected to the lower end of the contrast spring 20 by means of a rotary joint 25. When the counter force needs to be adjusted, the adjusting bolt 24 is rotated, and the adjusting bolt 24 drives the counter spring 20 to ascend or descend integrally, so that the counter force is adjusted. In order to facilitate the Ningdong adjusting bolt 24, the bottom of the adjusting bolt 24 is provided with an inverted Y-shaped plastic screw tab 29.

The present invention is installed through a chassis, and in consideration of the problems of fastening and convenience of installation, as shown in fig. 1 and 2, the chassis includes an upper slat 26 and a lower slat 27 arranged side by side, and a plurality of sets of bolt holes are correspondingly arranged on the upper slat 26 and the lower slat 27, and are adapted with locking bolts 28 and locking nuts. The upper lath 26 and the lower lath 27 are locked by a locking bolt 28 and a locking nut and clamped on a base body, and the base body can be selected from objects which can be easily clamped, such as a table edge, a cabinet edge and the like.
