Wearable hand function rehabilitation training robot

Abstract

This invention discloses a wearable hand function rehabilitation training robot, comprising an upper cover and a lower cover. A glove is mounted on the bottom of the lower cover, and an air pump is fixedly connected to the top of the lower cover. The output end of the air pump is connected via a first shunt pipe to a plastic coupling mechanism and a corrugated pipe to prevent fingers from deviating from their normal position. The upper cover is fixedly connected to the outer side of the top of the lower cover, and a hinged device for fixing the wrist is fixedly connected to the outer side of the lower cover. This invention, with its upper cover, first shunt pipe, plastic coupling mechanism and corrugated pipe to prevent fingers from deviating from their normal position, air pump, lower cover, and hinged device for fixing the wrist, can drive the fingers to flex and extend, thus achieving rehabilitation. Since most commercially available robots combine the main unit and glove separately, this invention combines the two, making it more convenient and easier to use, allowing for training anytime, anywhere. It ensures normal finger flexion and extension, prevents deviation, and also prevents the glove from falling off during training.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wearable hand function rehabilitation training robot. Background Technology

[0002] Currently, there is a lack of rehabilitation equipment for stroke patients with hand dysfunction. Approximately 75% of stroke patients will have varying degrees of sequelae after the onset of the disease. Among the many sequelae, hemiplegia has the highest incidence. Among the rehabilitation of hemiplegia, the rehabilitation of hand function is the most difficult. Most of the glove on the market is separate from the main unit, and the fingers of the gloves on the market will drift when flexing and extending. At the same time, the gloves on the market will fall off when flexing and extending. Therefore, we propose a wearable hand function rehabilitation training robot. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The components of this application, including the top cover 1, battery 2, circuit board 3, two-position two-way solenoid valve 4, first shunt pipe 5, plastic coupling mechanism and bellows 6 to prevent finger deviation, second shunt pipe 61, plastic coupling structure 62, bellows 63, finger 64, glove surface 65, glove 7, power switch 8, two-position three-way solenoid valve 9, air pump 10, charging port 11, bottom cover 12, wrist-fixing hinge device 13, damping hinge 131, and wrist-pressing structure 132, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0027] Please see Figures 1-11A wearable hand function rehabilitation training robot includes an upper cover 1 and a lower cover 12. A glove 7 is installed at the bottom of the lower cover 12, and an air pump 10 is fixedly connected to the top of the lower cover 12. The output end of the air pump 10 is connected via a first shunt pipe 5 to a plastic coupling mechanism and a bellows 6 to prevent finger deviation during flexion and extension, ensuring that the finger 64 moves only perpendicular to the bellows 63 and does not sway left or right. The upper cover 1 is fixedly connected to the outer side of the top of the lower cover 12, and a fixed wrist is fixedly connected to the outer side of the lower cover 12. The hinge device 13 can fix the wrist position, making the palm and the device more stable. The hinge device 13 that fixes the wrist includes a damping hinge 131 and a wrist pressing structure 132, which can drive the fingers 64 to bend and perform flexion and extension movements to achieve rehabilitation. Since the main unit and glove 7 are basically separate in the market, the present invention combines the two, which is more convenient and easy to use, and can be trained anytime and anywhere. It can ensure the normal flexion and extension of the fingers 64, prevent deviation, and prevent the glove 7 from falling off during training.

[0028] To prevent fingers from deviating from the plastic coupling mechanism and bellows 6, a second diversion pipe 61, a plastic coupling structure 62, a bellows 63, a finger 64, and a glove surface 65 are included. The end of the second diversion pipe 61 is connected to the first diversion pipe 5. Multiple plastic coupling structures 62 and bellows 63 are provided on the surface of the finger 64. The second diversion pipe 61 extends to the outermost bellows 63, and the glove surface 65 is provided on the outer side of the finger 64. The plastic coupling structures 62 are connected end to end in a snap-fit ​​manner and then glued to the glove surface 65. When air enters the second diversion pipe 61, the plastic coupling structure 62 moves downward, causing the finger 64 to bend, achieving the effect of finger training. A two-position two-way solenoid valve is provided between the air pump 10 and the first diversion pipe 5. The two-position two-way solenoid valve 4 and the two-position three-way solenoid valve 9 can divert the gas, allowing the gas to enter the plastic coupling mechanism and bellows 6 to prevent the fingers from deviating from the device, thus causing the fingers 64 to flex and extend downwards. The two-position two-way solenoid valve 4 and the two-position three-way solenoid valve 9 control the "flexion" and "extension" of the fingers 64 respectively. The top of the upper cover 1 is fixedly connected to the power switch 8, and the outer side of the upper cover 1 is provided with a charging port 11 for charging the battery 2. The bottom of the upper cover 1 is fixedly connected to the battery 2, which can provide power to the air pump 10. The top of the lower cover 12 is fixedly connected to the circuit board 3. The outer side of the damping hinge 131 is provided with a wrist-pressing structure 132, and there are two damping hinges 131 and two wrist-pressing structures 132. The friction generated by the damping hinge 131, combined with the wrist-pressing structure 132, presses the wrist, allowing the wrist to fit tightly against the device, resulting in better rehabilitation effects.

[0029] In use, the device includes an upper cover 1, a first diversion tube 5, a plastic coupling mechanism and a bellows 6 to prevent fingers from deviating, an air pump 10, a lower cover 12, and a hinged device 13 for fixing the wrist. It can drive the fingers 64 to bend and perform flexion and extension movements to achieve rehabilitation. Since most products on the market have the main unit and glove 7 separate, this invention combines the two, making it more convenient and easier to use. It can be trained anytime and anywhere, ensuring the normal flexion and extension of the fingers 64, preventing deviation, and preventing the glove 7 from falling off during training.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
