Description

Technical Field

[0001] The invention relates to the technical field of hand rehabilitation, and in particular to a portable hand rehabilitation training device. Background Art

[0002] Hand rehabilitation training devices are a type of medical equipment or auxiliary tools designed to assist in the recovery of hand function. These devices are usually used to help patients whose hand functions are limited due to diseases or injuries to conduct effective rehabilitation training to speed up the recovery process and improve hand dexterity and strength.

[0003] After searching, the Chinese patent document announcement number: CN217091317U discloses a hand rehabilitation training device, including a pneumatic glove, a bellows is provided on the pneumatic glove, and also includes a shell, a host computer and a slave computer; the host computer includes an optical position tracker and a control circuit board 1, the optical position tracker is installed on the front of the shell, and the acquisition port of the control circuit board 1 is connected to the optical position tracker; the slave computer includes a control circuit board 2, a relay, an air pump, an air pump and an electromagnetic valve group, the control circuit board 2 is respectively connected to the air pump and the air pump through a relay, the air outlets of the air pump and the air pump are connected to the electromagnetic valve group, and the electromagnetic valve group is connected to the bellows on the pneumatic glove through an air circuit pipe. The user of the present invention only needs to use the healthy hand to wear the pneumatic glove for the affected hand to start mirror training, and can train independently without the help of a doctor or family.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above patents mention in the beneficial effects: "In the hand rehabilitation training device of the present invention, the user uses the healthy hand to wear a pneumatic glove for the affected hand (the pneumatic glove is a product that can be directly purchased on the market). The action of the healthy hand is captured by the optical position tracker, and then converted into a control instruction through analysis and processing by the host computer. The control instruction is transmitted to the lower computer by the host computer through wireless or wired communication. The lower computer starts the vacuum pump, the inflation pump and the solenoid valve group, thereby controlling the bellows on the affected hand to inflate and evacuate air separately or in any combination, so as to complete the corresponding mirror action of the affected hand. The hand rehabilitation training device of the present invention is different from the traditional pneumatic glove. Compared with the rehabilitation gloves, an optical position tracker is added. The user only needs to wear the pneumatic glove on one affected hand to carry out mirror training. The other healthy hand has no physical connection with the hand rehabilitation training device. It only needs to make movements for the optical position tracker to collect, making the rehabilitation training process simpler and more convenient, and the training can be completed independently without the assistance of others. "Although the above patent uses the movements collected by the optical position tracker to enable the device to complete the training independently, in the specific operation process, as the rehabilitation training progresses, the hand will recover, but it still needs to be controlled to carry out rehabilitation training, and it cannot flexibly adapt to the patient. Therefore, in view of the above shortcomings, a portable hand rehabilitation training device is proposed. Summary of the invention

[0047] The front and rear sides of the spring 2 36 are fixedly connected with parallel plates 37 to limit the spring 2 36 so that the spring 2 36 can be evenly stressed. The far side of the elastic component is fixedly connected with a sliding plate 38. The outer parts of the two parallel plates 37 are slidably connected to the inner wall of the bottom plate 1.

The vertical plate 39 can slide horizontally due to the limitation of the bottom plate 1. The far end of the top side of the two sliding plates 38 is fixedly connected with the vertical plate 39. The far top ends of the two vertical plates 39 are fixedly connected with an arc plate 40 for limiting the cable.

[0048] Working principle: After a long period of rehabilitation training, in order to reduce the operation process of the device, the fingers that have been rehabilitated are placed inside the multiple semi-ring columns 6, and then the hooks 15 are hung on the inner walls of the semi-ring columns 6, and then the wrists are fitted to the bottom side of the connecting block 20, and then the fixing belt 2 32 is passed through the adjustment plate 31, and then a certain space is left with the fixing belt 1 30. After reaching the limit, the square opening 34 is passed through the right-angle plate 33 and the engagement is completed. The fixing belt 2 32 is a plastic material, so that it can be stably engaged with the right-angle plate 33, and then the user shakes his fingers, so that the finger sleeve 5 can drive the semi-ring column 6 to move forward. The hook 15 is rotated, thereby driving the hook 15 to move, and the cylinder 14 fixed to the hook 15 is restricted inside the connecting shaft 11, and the connecting shaft 11 drives the ball 10 to move inside the connecting plate 9, so that it can be used at different angles, and then the hook 15 drives the cylinder 14 to slide outside the connecting shaft 11, and at the same time, the cylinder 14 also squeezes the strong spring 13, so that the strong spring 13 can store elastic potential energy, and then gives the finger sleeve 5 a reverse force to provide the force required for rehabilitation training, so that the device can adapt to the patient's needs without the need for a control device, reduce the operation steps, and then improve the flexibility of the device;

[0049] When the controller 2 provides the air pipe 4 in the connector 3 with a curved and extended gas, the rotation of one of the air pipes 4 will drive the strip plate 16 to rotate, thereby driving the side strip plate 17 to rotate, and then driving the rotating plate 19 to rotate, and the rotating plate 19 will be limited by the limit plate 21, so that the rotating plate 19 can reciprocate horizontally, and then drive the rotating plate 19 to slide, thereby driving the square plate 23 to slide, and then driving the slide plate 29 in contact with the skin to slide, and then the blood-dispersing roller 41 at the bottom of the slide plate 29 will produce friction with the skin. The friction force is used to improve blood circulation, thereby improving the treatment effect. When the slide plate 29 contacts the skin, it will be subjected to a reaction force, so that the slide plate 29 can push the sliding plate 28 to slide, thereby pushing the trapezoidal block 27 to slide, and then pushing the two sliding blocks 26 to slide to the far side, and then while sliding outside the fixed rod 24, it can squeeze the spring 1 25, so that the spring 1 25 can store elastic potential energy, and then give the slide plate 29 a reverse force, so that the blood-dispersing roller 41 can fit the skin more closely, thereby further improving the treatment effect.

[0050] When the controller 2 is in use, the cable is connected to a power source. When not in use, the cable is wound around the far side of the two arc plates 40. The two arc plates 40 will push the vertical plate 39 to slide after being subjected to force, thereby driving the sliding plate 38 to slide, thereby pushing a parallel plate 37 to slide toward the near side. The parallel plate 37 will slide outside the fixing rod 35 and squeeze the spring 2 36, so that the spring 2 36 can store elastic potential energy, and then give the arc plate 40 a reverse force to improve the effect of fixing the cable, thereby placing the device.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
