Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, specifically to a thread-driven rehabilitation glove. Background Technology

[0002] Stroke is one of the most serious diseases threatening human health. Not only does it have a high mortality rate, but even after surviving the initial stroke, it can cause hemiplegia and other problems, severely impacting the patient's quality of life. To help hemiplegic patients recover, the most common approach is rehabilitation training. This involves guiding patients to move using rehabilitation equipment, allowing their muscles, joints, nerves, and other tissues to gradually recover during the training process.

[0003] For finger rehabilitation training, rehabilitation gloves are commonly available on the market. Existing rehabilitation gloves can be divided into mechanical and pneumatic types based on their actuation methods. However, existing mechanical rehabilitation gloves are relatively bulky and lack portability; pneumatic gloves, on the other hand, require advanced manufacturing technology and are costly. Therefore, there is a need in this field for a rehabilitation glove that balances portability and production cost. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a wire-driven rehabilitation glove.

[0005] To achieve the purpose of this utility model, this application provides the following technical solution.

[0006] In a first aspect, this application provides a thread-driven rehabilitation glove, the rehabilitation glove comprising a glove body, a drive unit mounted on the back of the glove body, and a micro motor for driving the drive unit to operate. The drive unit includes at least one Bowden line and a top plate matching the Bowden line. The top plate is fixed to the fingertips of the glove body. The Bowden line includes an outer sheath and a flexible cord located inside the sheath. One end of the flexible cord is fixed to a telescopic component of the micro motor, and the other end abuts against and is fixed to the top plate. One end of the sheath is fixed to the housing of the micro motor, and the other end abuts against the top plate.

[0007] Bowden wire, most commonly used in bicycle brake cables, appears to be a flexible thread, but its internal flexible cord is made of high-stiffness metal wire that can transmit tension or thrust. Therefore, when a micro-motor pulls the flexible cord backward or pushes it forward, it directly acts on the top plate, causing the top plate to move forward or backward. Since the glove itself is non-stretchable when worn on the patient's hand, one side of the drive unit can extend or shorten while the other side remains non-stretchable, causing the entire drive unit to bend. This guides the patient's fingers in flexion movements, achieving rehabilitation training. This application uses Bowden wire and a micro-motor for drive, resulting in a simpler structure, better portability, and lower cost, making it more widely applicable.

[0008] In one embodiment of the first aspect, a limiting plate is provided at the finger heel of the glove body, and the sheath passes through and is fixed to the limiting plate. The purpose of providing the limiting plate is to ensure that the bending of the actuator only occurs at the finger area, making rehabilitation training more precise.

[0009] In one embodiment of the first aspect, multiple guide plates are provided between the top plate and the limiting plate, the bottom of the guide plates being fixed to the glove body, and the sheath passing through all the guide plates. By providing guide plates, the Bowden lines at the finger area are divided into multiple segments, each segment being shorter in length and more stable when bending.

[0010] In one embodiment of the first aspect, each finger has three Bowden threads on the glove body. Using three Bowden threads, a micromotor controls the curvature of these three threads, enabling the finger to rotate slightly to the left and right, thus better achieving the rehabilitation training effect. A triangular arrangement facilitates this rotational effect and also effectively increases the service life of the drive unit. In one embodiment of the first aspect, the three Bowden lines are arranged in a triangular pattern.

[0011] In one embodiment of the first aspect, each Bowden cable is matched with a micro motor. The micro motors of this application are linear motors, such as common thumb motors, which drive the cables to perform axial linear motion.

[0012] In one embodiment of the first aspect, the glove body includes an installation unit and finger sleeves. The drive unit is mounted on the back of the installation unit, and the finger sleeves are fixed to the front of the installation unit. The finger sleeves can be in the form of Velcro or elastic straps, designed to securely hold the patient's fingers and prevent slippage between the glove body and the patient's fingers during rehabilitation training, which could affect the rehabilitation effect.

[0013] In one embodiment of the first aspect, the installation unit is made of a flexible and non-stretchable material, such as common fabrics, PVC, engineering plastics, etc.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The rehabilitation gloves described in this application are driven by Bowden wire and a micro motor. They have a simple structure, good portability, and low cost, making them suitable for a wider range of applications. Attached Figure Description

[0020] Unless otherwise defined, the technical or scientific terms used in this specification and claims shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. All values ​​listed herein, ranging from the minimum to the maximum, refer to all values ​​obtained by incrementing the minimum and maximum values ​​by one unit when the difference between the minimum and maximum values ​​is more than two units.

[0021] The following describes specific embodiments of this utility model. It should be noted that, in order to provide a concise description, this specification cannot provide a detailed description of all features of the actual embodiments. Without departing from the spirit and scope of this utility model, those skilled in the art can modify and substitute the embodiments of this utility model, and the resulting embodiments are also within the protection scope of this utility model. Example

[0022] The embodiments of this utility model will be described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments. Example

[0023] A type of thread-driven rehabilitation glove, the structure of which is as follows: Figure 1 , Figure 2 As shown, it includes a glove body extending to the upper part of the patient's wrist and the lower part of the forearm. The glove body includes a PVC mounting unit 1, the overall shape of which is similar to the shape of human fingers, palm, and wrist, and finger sleeves 2 (located on the palm side) are fixed to the fingers. A box is located at the wrist position, inside which 15 micro motors 3 are fixedly installed. A semi-circular top plate 7 (on the back of the hand side) is fixed to the mounting unit 1 at the fingertip position, and multiple semi-circular guide plates 6 are also fixedly installed on each finger. In the static state, the guide plates 6 and the top plate 7 are parallel. At the connection between the finger and the palm, five limiting plates 5 are also fixed to the mounting unit 1. In this application, five drive units are installed on the back of the hand side, each drive unit corresponding to drive one finger, and each drive unit includes three Bowden wires 4 arranged in a triangular pattern. The tail end of the sheath of each Bowden wire 4 is fixed to a micro motor 3, and the front end passes through the limiting plate 5 and all the guide plates 6 in sequence, and the sheath and the limiting plate 5 are also fixed. The center of Bowden line 4 is a flexible cable, the tail end of which is connected to a micro motor 3, and the front end of which is fixed to the top plate 7.

[0024] The working principle of this rehabilitation glove is as follows: When the micro motor 3 extends forward (from the base of the finger to the fingertip), the flexible cord of the Bowden wire 4 extends forward simultaneously, thereby pushing the top plate 7 forward. This increases the distance between the top plate 7 and the limiting plate 5. Since the mounting unit 1 cannot extend or retract, the upper part of the drive unit becomes longer while the lower part remains unchanged, causing the drive unit to bend downwards. Figure 3 As shown.

[0025] When the micro motor 3 is pulled backward (from the fingertip to the base of the finger), the flexible cord of the Bowden wire 4 is pulled backward in sync, thereby pushing the top plate 7 to move backward. This shortens the distance between the top plate 7 and the limiting plate 5. Since the mounting unit 1 cannot extend or retract, the upper part of the drive unit shortens while the bottom remains unchanged. The drive unit gradually returns to a straight state, becoming as follows: Figure 1 As shown in the diagram. If you continue to pull backward, the drive unit will tilt upward, as... Figure 4 As shown.

[0026] The above description of the embodiments is intended to enable those skilled in the art to understand and apply this application. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, this application is not limited to the embodiments described herein, and any improvements and modifications made by those skilled in the art based on the disclosure of this application without departing from the scope and spirit of this application are within the scope of this application.
