Description

Technical Field

[0001] This utility model relates to the field of rehabilitation glove technology, specifically to a wearable pneumatic rehabilitation glove. Background Technology

[0002] Rehabilitation gloves are assistive medical devices primarily used to help patients with hand dysfunction undergo rehabilitation training. They are typically made of soft materials and have built-in actuators that provide passive or active hand movement assistance. These gloves help patients regain hand functions such as grasping and extension by precisely controlling finger joint movements, while also improving joint range of motion and muscle strength. Their intelligent system can monitor training data in real time and automatically adjust the training intensity based on the patient's recovery progress. Rehabilitation gloves are particularly suitable for patients with hand dysfunction caused by stroke sequelae, post-operative hand injuries, or neurological diseases, effectively preventing joint stiffness and muscle atrophy.

[0003] Pneumatic rehabilitation gloves use an air pump to inflate / de-inflate flexible air bladders, which expand and contract to move the fingers in flexion and extension movements. These devices are driven by air pressure, eliminating mechanical friction and reducing the risk of skin damage.

[0004] For example, Chinese Patent Publication No. CN216536041U discloses a multi-joint pneumatic flexion structure and a pneumatic flexion glove. The pneumatic flexion glove includes a glove body and a multi-joint pneumatic flexion structure, which is disposed on the fingers of the glove body. The multi-joint pneumatic flexion structure includes a telescopic airbag, a ventilation pipe, an airbag support frame, and a bottom connecting strip. One end of the telescopic airbag is connected to the ventilation pipe. The telescopic airbag is supported on the bottom connecting strip by multiple telescopic airbag supports. The bottom connecting strip has multiple connecting areas on the side away from the airbag support frame, which are used to connect with the glove. The bottom connecting strip is integrally formed with the airbag support frame. In this disclosed device, the telescopic airbag needs to be inserted and installed in the through hole in the middle of the airbag support frame. However, the telescopic airbag has a bulging corrugated tube portion with a diameter larger than the through hole, making the installation of the telescopic airbag inconvenient and causing considerable difficulties in installation.

[0026] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0029] like Figures 1-8 As shown, a wearable pneumatic rehabilitation glove includes a glove body 10 and a finger drive mechanism 20 mounted on the back of the glove body 10. The finger drive mechanism 20 includes a mounting plate 30, a support frame 40, and a telescopic airbag 50. The mounting plate 30 is fixed to the glove body 10. The support frame 40 includes a support block 41 and a retainer 42. The support block 41 is fixedly connected to the mounting plate 30, and the retainer 42 is engaged with the support block 41 to limit the telescopic airbag 50 on the support frame 40.

[0030] Using the above technical solution, the telescopic airbag 50 is locked onto the support block 41 by the snap-fit ​​sleeve 42, which facilitates installation.

[0031] The support block 41 includes a base frame 411, a vertical frame 412, and a top frame 413 that are fixed together. The vertical frame 412 has a semi-circular first groove 414. The base frame 411 is located at the bottom of the vertical frame 412, and the top frame 413 is located at the top of the vertical frame 412. The sleeve 42 has a C-shaped structure. The sleeve 42 has a semi-circular second groove 421 on the side opposite to the support block 41. The first groove 414 and the second groove 421 match so that when the sleeve 42 is engaged with the support block 41, they merge into a cylindrical hole 60 for limiting the telescopic airbag 50. The base frame 411 has a first rectangular groove 415, and the top frame 413 has a second rectangular groove 416. The upper and lower ends of the sleeve 42 are provided with protruding locking tongues 422. The locking tongues 422 are engaged in the first rectangular groove 415 and the second rectangular groove 416 respectively to lock the sleeve 42 onto the support block 41. The sleeve 42 and the support block 41 cooperate to form a cylindrical hole 60 for restricting the telescopic airbag 50, thereby facilitating the restriction of the telescopic airbag 50 on the support frame 40. The sleeve 42 is locked onto the support block 41 by the locking tongue 422, which facilitates installation. During installation, the telescopic airbag 50 is inserted into the first groove 414 from one side, and then the sleeve 42 is secured onto the support block 41, thereby completing the restriction of the telescopic airbag 50 in the support frame 40, which is convenient for installation.

[0032] The second rectangular groove 416 extends vertically through the top frame 413. When it is necessary to remove the sleeve 42, a rod-shaped tool is inserted from the top end of the top frame 413 into the second rectangular groove 416 to push the upper locking tongue 422 of the sleeve 42 away from the second rectangular groove 416, thereby facilitating the removal of the sleeve 42.

[0033] The base frame 411 is provided with a first slide rail 417, and the top frame 413 is provided with a second slide rail 418 arranged parallel to the first slide rail 417. The lower end of the sleeve 42 has a first sliding groove 423, and the upper end of the sleeve 42 has a second sliding groove 424. The first slide rail 417 is located in the first sliding groove 423, and the second slide rail 418 is located in the second sliding groove 424. Through the cooperation of the slide rail and the sliding groove, the sleeve 42 is axially limited, ensuring a stable connection between the sleeve 42 and the support block 41.

[0034] The telescopic airbag 50 includes multiple alternating straight tube sections 51 and corrugated tube sections 52. The straight tube sections 51 are correspondingly arranged with the support frame 40 and are located within the cylindrical hole 60 formed by the merging of the sleeve 42 and the support frame 40. The outer diameter of the corrugated tube section 52 is larger than the outer diameter of the straight tube section 51, and the corrugated tube section 52 is located between adjacent support frames 40. One end of the telescopic airbag 50 is closed, and the other end is connected to a connecting connector 70 for connecting to an air pump. By inflating or deflating the airbag, the corrugated tube section 52 is driven to extend or retract, causing the telescopic airbag 50 to extend and retract, thereby causing the mounting plate 30 to bend, which in turn causes the fingers of the glove body 10 to bend, and thus causes the fingers wearing the glove body 10 to complete the flexion and extension movements.

[0035] A stiffening rib 80 is fixedly connected to the bottom of the support block 41. The stiffening rib 80 is fixed to the mounting plate 30, and its thickness is less than that of the support block 41. By using the thinner stiffening rib 80 to fix the support block 41 to the mounting plate 30, the connection width is reduced, facilitating bending of the mounting plate 30. The two sides of the retaining sleeve 42 are flush with the two sides of the support frame 40. This ensures that the end of the corrugated pipe section 52 contacts the side plane of the support frame 40, resulting in a flat contact surface and uniform stress on the corrugated pipe section 52.

[0036] A control valve 71 is provided on the connecting joint 70. The control valve 71 is used to control the connection channel between the telescopic airbag 50 and the air pump, so that when the corresponding finger movement is not required, the corresponding telescopic airbag 50 can be closed by the control valve 71, thereby realizing individual control of finger flexion and extension movements.

[0037] The parts not covered in this technical solution can be implemented using existing technologies.

[0038] The foregoing has shown and described the basic principles, main features, and characteristics of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model includes the appended claims and their equivalents.
