Description

Technical Field

[0001] This utility model relates to the field of rehabilitation aids, specifically an inflatable glove for assisting hand joint movement. Background Technology

[0002] The hand, as one of the most flexible and complex organs in the human body, plays a vital role in daily life. However, hand tissue injuries caused by external forces, such as fractures, tendon ruptures, and nerve damage, are very common in clinical practice. These injuries not only cause patients severe pain and functional impairment but can also lead to long-term hand deformities and disability, seriously affecting their quality of life and work ability. Therefore, rehabilitation training after hand injuries is a crucial step in restoring hand function and reducing the degree of disability. In the field of hand rehabilitation, traditional rehabilitation methods mainly include physical therapy, occupational therapy, and joint mobilization techniques. These methods aim to promote blood circulation in the hand, relieve muscle tension, restore joint range of motion, and ultimately improve hand motor function and daily living abilities through professional techniques and training. With the advancement of technology, more and more assistive devices are being applied to hand rehabilitation. These devices help patients complete flexion, extension, and rotation movements of the hand joints by simulating natural human movements or providing specific mechanical stimulation, thereby accelerating the rehabilitation process. Among them, inflatable gloves, as a new type of hand rehabilitation assistive device, have attracted much attention due to their ease of operation and significant effects.

[0003] Currently, various inflatable gloves are available on the market for use in hand rehabilitation. These gloves typically use compressed gas as a power source, and through repeated inflation and deflation, the bellows or other elastic elements on the glove expand and contract, thereby driving the hand joints to perform reciprocating flexion and extension movements. This passive training method not only helps restore the range of motion of the joints, but also promotes blood circulation in the hand and relieves muscle tension and pain.

[0004] For example, the Chinese authorized patent with publication number CN 219501463 (auxiliary motion device and pneumatics for pneumatic gloves) includes an air bladder for extending and retracting along the extension direction of the air bladder under the action of gas; an air tube connected to the air bladder for introducing gas into the air bladder; a bracket for fixing the air bladder, one end of the bracket being connected to the air bladder and the other end of the bracket being connected to the pneumatic glove; the air bladder and the bracket are integrated, which facilitates the assembly of the auxiliary motion device.

[0005] Although the aforementioned existing technology has the function of assisting hand movement, the airbag is a single corrugated tube structure. When inflated, the corrugated tube not only expands and compresses the fingers to move, but also increases its own length, and the increase is relatively large. Therefore, the middle part of the airbag will arch outward and not fit the fingers, thus affecting the function of assisting the rehabilitation of the fingers. Utility Model Content

[0006] The purpose of this invention is to provide an inflatable glove for assisting hand joint movement, in order to solve the problem mentioned in the background art that the air bladder is a single corrugated tube structure. When inflated, the corrugated tube not only expands and presses the fingers to move, but also increases its own length by a large margin. As a result, the middle part of the air bladder will arch outward and not fit the fingers, thus affecting the auxiliary rehabilitation function of the fingers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an inflatable glove for assisting hand joint movement, comprising a glove body, the glove body including finger parts, palm and wrist, the wrist being integrally connected to the lower end of the palm, and multiple finger parts being integrally connected to the upper end of the palm, the multiple finger parts corresponding to the thumb, index finger, middle finger, ring finger and little finger positions respectively, a fixed finger sleeve is provided at the front end of the finger part, and joint openings are provided on the front and rear ends of the fixed finger sleeve at positions corresponding to the hand joints, and finger inflation auxiliary structures are provided on the palm and the rear ends of the multiple finger parts;

[0008] The finger inflation assist structure includes an airbag fixing unit and a second inflation assist component. There are multiple airbag fixing units. Adjacent airbag fixing units and the innermost airbag fixing unit and the second inflation assist component are connected by a connecting hose body. The connecting hose body is positioned corresponding to the hand joint.

[0009] The airbag fixing unit includes two first inflation assist components, which are connected by a middle fixing hose. Each of the first and second inflation assist components includes an airbag expansion part and a connecting rigid tube, which are alternately arranged.

[0010] The other end of the second inflation assist component is connected to an inflation hose body, and the inflation hose body, the second inflation assist component, the airbag fixing unit and the connecting hose body are internally connected.

[0011] Preferably, the palm and wrist rear end array is connected to a palm inflation auxiliary structure, and the palm inflation auxiliary structure is provided with a tube body that is the same as the airbag fixing unit, the connecting hose body, the second inflation auxiliary component and the inflation hose body structure.

[0012] Preferably, a gas distribution bladder is fixed in the middle of the rear end of the palm, an inflation tube is installed in the center of the outer end of the gas distribution bladder, and the other end of the multiple inflation hoses is connected to the gas distribution bladder.

[0013] Preferably, the finger inflation auxiliary structure and the palm inflation auxiliary structure are engaged and fixed to the glove body by a fixing component. The fixing component has a fixing hole groove in the center for the passage of the middle fixing hose body, and an entry groove is opened at the lower end of the side of the fixing component. The height of the entry groove is smaller than the diameter of the fixing hole groove.

[0014] Preferably, a first palm-side connecting part is integrally connected to one side of the palm, and a second hook-and-loop fastener is sewn and fixed to the outer side of the front end face of the first palm-side connecting part. A second palm-side connecting part is integrally connected to the other side of the palm, and a first hook-and-loop fastener is sewn and fixed to the outer side of the rear end face of the second palm-side connecting part. The first hook-and-loop fastener hooks and the second hook-and-loop fastener hooks. A lateral extension reinforcement part is integrally connected to the upper end of one side of the palm between the thumb and index finger positions. The lateral extension reinforcement part is inclined, and a first hook-and-loop fastener is sewn and fixed to the outer side of the front end face of the lateral extension reinforcement part. The first hook-and-loop fastener hooks and the first hook-and-loop fastener hooks.

[0015] Preferably, a first wrist-side connecting part is integrally connected to one side of the wrist, and a third hook and loop fastener is sewn and fixed to the outer side of the front end face of the first wrist-side connecting part.

The second hook and loop fastener hook and the third hook and loop fastener hook are hooked together.

[0016] Preferably, the upper and lower ends of the rear end of the fixed finger sleeve are glued to the glove body through a fixing part.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) In this utility model, the finger inflation auxiliary structure includes an airbag fixing unit and a second inflation auxiliary component. The airbag fixing unit includes two first inflation auxiliary components. Both the first and second inflation auxiliary components are composed of multiple alternately designed airbag expansion parts and connecting hard tubes. The intermediate fixing hose and connecting hose used for delivery and connection are silicone tubes. Therefore, only the airbag expansion part can expand. When air enters the airbag expansion part, it only expands longitudinally and will not affect the length. However, after the longitudinal expansion drives the finger movement, the airbag expansion part will be stretched and deformed. It can adapt to the changes when the finger is bent and will not change its own length due to its own structural design. Therefore, it will not arch as inflation proceeds and will always fit the finger. This solves the problem that the current airbag is a single corrugated tube structure. When inflated, the corrugated tube will not only expand and press the finger movement, but also increase its own length. The increase is relatively large, so the middle part of the airbag will arch outward and not fit the finger, thus affecting the auxiliary rehabilitation function of the finger.

[0019] (2) In this utility model, the multi-point connection design of the Velcro (second Velcro loop, first Velcro hook, third Velcro loop, second Velcro hook, first Velcro loop), combined with the side extension reinforcement, not only makes the wearing process simple and quick, but also allows for fine adjustment according to hand size to ensure that the glove fits the hand tightly. In addition, the presence of the side extension reinforcement pulls the fixed finger sleeves at the finger positions toward the palm, avoiding the problem of the fixed finger sleeves not fitting completely with the fingers during exercise.

[0020] (3) In this utility model, the reasonable layout of the connecting hose body is precisely aligned with the position of the hand joint, and the presence of the joint opening on the fixed finger sleeve avoids the structure from pressing on the joint position, reducing user discomfort and alleviating joint stiffness.

[0021] (4) In this utility model, the alternating left and right design of multiple fixing components in each group, as well as the design of fixing holes and entry slots on the fixing components, not only ensures the stable installation of the inflatable structure, but also facilitates maintenance and replacement, thereby increasing the overall durability and service life of the gloves.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] One embodiment of this utility model provides an inflatable glove for assisting hand joint movement, comprising a glove body 1, which is specifically composed of finger portions 3, a palm portion 2, and a wrist portion 27. The wrist portion 27 is directly connected to the lower end of the palm portion 2, while the multiple finger portions 3 correspond to the positions of the thumb, index finger, middle finger, ring finger, and little finger, respectively, and are integrally connected to the upper end of the palm portion 2.

[0032] (1) The design of the finger part and the fixed finger sleeve, such as Figure 1 and Figure 5 As shown:

[0033] The finger section 3 has a fixed finger sleeve 14 at its front end. The front and rear ends of the fixed finger sleeve 14 have joint openings 16 corresponding to the hand joints, allowing for unrestricted finger joint movement. This ensures comfort when the finger is bent under inflation pressure, avoids external structural pressure on the joint, and promotes joint flexibility. The upper and lower ends of the rear end of the fixed finger sleeve 14 are glued to the glove body 1 via fixing parts 15, ensuring the stability of the finger during rehabilitation.

[0034] (2) Inflatable auxiliary structure design, such as Figure 2 , Figure 3 and Figure 6 As shown:

[0035] The finger inflation assist structure 17 includes multiple airbag fixing units 19 and a second inflation assist component 25. Adjacent airbag fixing units 19 and the innermost airbag fixing unit 19 are connected to the second inflation assist component 25 via connecting hoses 24, with the connection positions corresponding to the hand joints. It precisely corresponds to positions other than the joints, providing targeted pressure to facilitate finger bending for rehabilitation.

[0036] Each airbag fixation unit 19 includes two first inflation assist components 20, which are connected by a central fixed hose body 23. Both the first inflation assist component 20 and the second inflation assist component 25 include an airbag expansion section 21 and a connecting rigid tube body 22, arranged alternately. This enhances structural stability, ensures uniform gas distribution, and improves rehabilitation efficiency. The other end of the second inflation assist component 25 is connected to an inflation hose body 26, and the inflation hose body 26, the second inflation assist component 25, the airbag fixation unit 19, and the connecting hose body 24 are internally interconnected.

[0037] Furthermore, the intermediate fixed hose body 23 and the connecting hose body 24 used for delivery and connection are made of silicone tubing, so the only structure that can expand is the airbag expansion part 21.

[0038] The palm 2 and wrist 27 are provided with a palm inflation assist structure 18 at the rear end. The structure is the same as the finger inflation assist structure 17, but the size and number are different. The basic structure and basic principle are the same. At the same time, it enhances the rehabilitation effect of the fingers and palm and promotes the overall recovery of hand function.

[0039] A gas distribution bladder 31 is fixed in the middle of the rear end of the palm 2, and an inflation tube 32 is connected to it. Multiple inflation hoses 26 are connected to the gas distribution bladder 31. By inflating and deflating the inflation tube 32, the expansion and contraction of each air bladder expansion part 21 are realized, which causes the hand joints to bend, achieving a comprehensive rehabilitation effect.

[0040] (3) Velcro design, such as Figures 1-4 As shown:

[0041] The palm 2 has a first palm-side connecting part 4 and a second palm-side connecting part 5 on both sides. The outer side of the front end of the first palm-side connecting part 4 is sewn and fixed with a second hook and loop fastener 10, and the outer side of the rear end of the second palm-side connecting part 5 is sewn and fixed with a first hook and loop fastener 12. The first palm-side connecting part 4 and the second palm-side connecting part 5 are hooked together by the second hook and loop fastener 10 and the first hook and loop fastener 12. A side extension reinforcement part 8 is integrally connected between the thumb position finger part 3 and the index finger position finger part 3 at the upper end of one side of the palm 2. The side extension reinforcement part 8 is inclined. The outer side of the front end of the side extension reinforcement part 8 is sewn and fixed with a first hook and loop fastener 9. The side extension reinforcement part 8 is hooked together with the first hook and loop fastener 12 by the first hook and loop fastener 9, providing additional oblique reinforcement to adapt to different hand sizes and ensure a tight fit.

[0042] The wrist 27 has a first wrist-side connecting part 6 and a second wrist-side connecting part 7 on both sides. The outer side of the front end face of the first wrist-side connecting part 6 is sewn and fixed with a third hook and loop fastener 11, and the outer side of the rear end face of the second wrist-side connecting part 7 is sewn and fixed with a second hook and loop fastener 13. The first wrist-side connecting part 6 and the second wrist-side connecting part 7 are hooked together by the third hook and loop fastener 11 and the second hook and loop fastener 13 to ensure wrist fixation and improve rehabilitation effect.

[0043] (4) Fixed component design, such as Figure 2 and Figure 7 As shown:

[0044] The finger inflation auxiliary structure 17 and the palm inflation auxiliary structure 18 are fixed to the glove body 1 by locking with the fixing components 28. The multiple fixing components 28 in each group are designed alternately on the left and right sides to make the locking effect better.

[0045] The fixing component 28 is provided with a fixing hole groove 29 for the intermediate fixing hose body 23 to pass through and an entry groove 30 for easy installation. Since the intermediate fixing hose body 23 is deformable, it can pass through the entry groove 30 with a smaller height. After the force is lost, the intermediate fixing hose body 23 resets and is locked in the fixing hole groove 29.

[0046] Working principle: The patient's five fingers are placed inside the five fixed finger sleeves 14. The first palm side connecting part 4 and the second palm side connecting part 5 are connected by the hooking of the second hook and loop part 10 and the first hook and loop part 12. Then, the first wrist side connecting part 6 and the second wrist side connecting part 7 are connected by the third hook and loop part 11 and the second hook and loop part 13. Finally, the side extension reinforcement part 8 is flipped downward so that the first hook and loop part 9 is attached to the exposed position of the first hook and loop part 12, completing the oblique reinforcement connection. At this time, the inflatable glove is basically worn.

[0047] During full rehabilitation exercises, the external gas delivery drive structure pumps gas into the gas distribution bladder 31 and distributes it to the inflatable auxiliary structures 17 for each finger and the inflatable auxiliary structure 18 for the palm. The inflatable part 21 of the bladder expands and presses the fingers and the back of the palm to move inward. When the external gas delivery drive structure extracts gas, each structure resets. The cyclical inflation and deflation process realizes the movement of the finger and wrist positions.

[0048] When only a single finger or wrist needs to be moved, the other inflatable hose sections 26 that do not need to be moved can be clamped with a clip. Only the inflatable hose section 26 in the moving position can be inflated and deflated normally, thereby achieving rehabilitation for a single position.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
