Detailed ways

As shown in Figures 1-3, the device for children's rehabilitation finger orthosis includes a base 1. The base 1 serves as the installation basis of the present invention and can be directly placed on a desktop for use. The bottom of the base 1 can be provided with a base with anti-skid function. For the feet, the base 1 has many specific structures. As shown in FIG. 1 , it can be a stand or a solid bottom box.

The left side of the top surface of the base 1 is provided with a support table 2 for supporting the palm, and the right side is provided with a rehabilitation trainer for confronting the fingers when flexing the fingers. In general, the rehabilitation training device is a weight block driven by a pull rope, and the pull rope goes around the roller above. When in use, the fingers are connected with the pull rope, and when the fingers are flexed, the counterweight is driven to rise, resulting in confrontation. Of course, it is also feasible to adopt other structures of rehabilitation trainers that can generate resistance.

The top of the support platform 2 is provided with a support protrusion 3 near the right end. The support protrusion 3 is mainly used to support the palm and the metacarpophalangeal joint to improve comfort. The shape of the support protrusion 3 is as close as possible to the It is appropriate to fit the natural curve of the human palm. The upper surface of the support table 2 located on the left side of the support protrusion 3 is inclined downward to the left to form the elbow joint support surface 4. When the hand is placed on the support table 2, there is a slight inclination to the rear, which is very comfortable and relaxing. The two sides of the support table 2 are correspondingly provided with a hook-and-loop strap 5, and the hook-and-loop strap 5 is used to fix the hand.

During the use of the present invention, the patient's hand is placed on the support table 2, the palm rests on the support protrusion 3, and then the fingers can be bent. The exercises for finger flexion and extension complete the shaping and correction of finger muscles. The shape of the inclined elbow joint support surface 4 and the support protrusion 3 of the present invention is more in line with ergonomic requirements, the user's hand rests on it, the comfort is very strong, and it is not easy to produce fatigue, which is suitable for long-term continuous exercise. On this basis, in order to further improve the comfort of the present invention, the forearm support can also be added. As shown in FIG. 1 , the left end of the elbow joint support surface 4 extends obliquely downward to form the forearm support surface 7, so that Comfort is better. In order to improve the structural strength of the forearm support surface 7 , a triangular rib plate 8 is provided between the forearm support surface 7 and the left end surface of the support platform 2 .

Here, the support protrusion 3 is composed of a mesh plate, and a fumigation chamber 6 for containing the medicinal liquid is provided below the support protrusion 3 , and an electric heater is provided in the fumigation chamber 6 . The medicinal liquid is heated by an electric heater to generate medicinal steam, and the hand is fumigated with traditional Chinese medicine, which has a better recovery effect.

In addition, in order to limit the finger to a certain extent, the correction effect is further improved. The upper part of the right end of the support table 2 is provided with four finger brackets 9 in the transverse direction, mainly for the other four fingers except the thumb. However, when the thumb bracket needs to be added, it can be added on the side of the support table 2 , which will not be described in the present invention. Each of the finger brackets 9 is composed of a finger tail support groove 10 , a middle support groove 11 and a fingertip support groove 12 . Between the right side wall of the support table 2 and both sides of the finger support groove 10, between the finger support groove 10 and both sides of the middle support groove 11, between the middle support groove 11 and the fingertip support groove 12. Between the sides, they are connected to each other by thin coil springs 13 . The design of the thin coil spring 13 does not affect the normal bending between the segments, but also has certain antagonism, which can improve the exercise effect.

In the process of rehabilitation training, the main training index of the present invention is the number of fingers. In order to facilitate the statistics of the number of fingers, as shown in FIG. 1 , the present invention also includes a counting detection component composed of a proximity sensor body 14 and a proximity body 15 , the proximity sensor body 14 is installed on the lower part of the right end surface of the support platform 2 , and the proximity body 15 is installed on the lower part of the fingertip support groove 12 . When a standard finger flexion is completed, the proximity body 15 is detected by the proximity sensor body 14 once, and the statistic is incremented by 1. In order to facilitate viewing, a controller can be designed in the present invention, and the controller is equipped with a near field communication module such as Bluetooth, WIFI, etc., and can be directly connected with a smart phone, which is convenient to use.

Because the traditional counterweight type rehabilitation training device has a relatively rigid reduction curve of the resistance during use, and when the resistance load is large, it is easy to cause secondary damage to the fingers, which is not suitable for patients in the early stage of rehabilitation. Therefore, the present invention proposes A rehabilitation training device is shown, or, as shown in FIG. 3 , the rehabilitation training device includes a chassis, a support frame, and four groups of confrontation components arranged side by side on the support frame.

The support frame includes two vertical bars 16 parallel to each other, an upper cross bar 17 and a lower cross bar 18 are arranged between the upper and lower parts of the two vertical bars 16, and the two ends of the upper cross bar 17 and the lower cross bar 18 are respectively It is fixed to the pole 16. A horizontal shaft 19 is arranged between the top ends of the vertical rods 16 . The opposing component includes an opposing spring 20 disposed between the upper cross bar 17 and the lower cross bar 18, the lower end of the opposing spring 20 is connected with the lower cross bar 18, and the upper end is connected with the lower end of the pull wire 21, the The upper end is connected to the fingertip support groove 12 after passing through the guide hole on the upper cross bar 17 and bypassing the guide wheel 22 installed on the horizontal shaft 19 .

During the bending process of the fingers, the resisting spring 20 is pulled by the pulling wire 21 . The resisting spring 20 generates enough resistance to resist in the process of finger flexion and extension, thereby improving the exercise effect and facilitating the rapid recovery and shaping of the finger muscle shape. In addition, due to the use of the confrontation spring 20 as the source of confrontation, compared with the traditional scheme of using the counterweight as the source of confrontation, the confrontation force of the present invention has a better ebb and flow curve, and it is not easy to cause secondary damage during the training process. Excellent.

Since different patients have large differences in the magnitude of the resistance during the confrontation training process, in order to improve the versatility of the present invention, a better approach may be that an adjustment device is also provided below the confrontation spring 20 Bolts 24 , the adjusting bolts 24 are inserted into the threaded holes on the lower cross bar 18 and form a threaded fit with the lower cross bar 18 . The upper end of the adjusting bolt 24 is connected with the lower end of the counter spring 20 through the rotary joint 25 . When it is necessary to adjust the opposing force, the adjusting bolt 24 is rotated, and the adjusting bolt 24 drives the resisting spring 20 to rise or fall as a whole to realize the adjustment of the opposing force. In order to facilitate the Ningdong adjusting bolt 24 , an inverted Y-shaped plastic twisting piece 29 is provided at the bottom of the adjusting bolt 24 .
