Description

Technical Field

[0001] This utility model relates to the field of basic biomedical experimental equipment technology, specifically to an upper limb electrical stimulation-assisted positioning glove. Background Technology

[0002] Various injuries to the central and peripheral nervous systems, especially brain injuries (such as stroke) and cerebral palsy, can lead to sensory and motor dysfunction in the upper limbs. For example, more than 80% of stroke patients and patients who have been hospitalized multiple times have upper limb dysfunction, and patients with cerebral palsy often have pronation deformities. This seriously affects patients' reintegration into their families and society and is a rehabilitation problem that urgently needs to be addressed.

[0003] Electrical stimulation is a common and effective intervention in the rehabilitation of upper limb dysfunction, but it is mostly used in rehabilitation training in medical institutions. Although there are small home-use electrical stimulation devices suitable for upper limb dysfunction, the need to attach electrode pads to the stimulated muscle groups makes them difficult for people without a medical background to operate directly, which limits the promotion of these devices and is not conducive to upper limb functional rehabilitation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an upper limb electrical stimulation-assisted positioning glove.

[0005] The specific technical solution is as follows:

[0006] An upper limb electrical stimulation-assisted positioning glove, comprising:

[0007] The glove body adopts a wearable flexible sleeve structure that extends from the metacarpophalangeal joint to the shoulder joint. The area corresponding to the metacarpophalangeal joint is provided with a fabric connecting part to achieve a fixed connection at the web of the hand. The palm area of ​​the glove body is provided with a finger sleeve structure for the fingers to pass through.

[0008] The fixing component is used to fit the glove body to the limb to prevent slippage and achieve a positioning function;

[0009] Muscle group location markers, drawn on the glove body, are used to identify the location of muscle groups; and

[0010] Electrical stimulation site markings are marked on the main body of the glove to identify commonly used electrical stimulation sites. The electrical stimulation site markings include a composite positioning mark consisting of concentric circular indicator lines and cross-shaped openings, used to mark the stimulation location.

[0011] Optionally, the fixing component includes a first restraint strap segment and a second restraint strap segment. The proximal end of the first restraint strap segment is connected to the rear region of the first shoulder of the glove body, and the distal end of the first restraint strap segment extends above the contralateral shoulder joint to the front region of the second shoulder for fixing. The second restraint strap segment is arranged in a mirror-symmetrical manner with the first restraint strap segment.

[0012] Optionally, both the first and second constraint band segments are provided with length adjustment buckles for adjusting the length.

[0013] Optionally, a fixing buckle is provided between the first constraint band segment and the second constraint band segment.

[0014] Optionally, the first restraint strap segment, the second restraint strap segment, and the glove body are provided with a detachable fastener at the intersection of the shoulder blade area. The detachable fastener includes a plug-in connector composed of a male fastener and a female fastener.

[0015] Optionally, the diameter of the circular indicator line is adapted to the standard electrode patch size.

[0016] Optionally, the glove body has three clinically adaptable configurations: left limb applicable, right limb applicable, and bilateral limb applicable. Each configuration can be selectively configured according to the affected side of the hemiplegic patient.

[0017] Optionally, the inner layer of the glove body is made of sweat-absorbing and breathable cotton material.

[0018] Optionally, the outer layer of the glove body is made of a wear-resistant and waterproof material.

[0019] Optionally, the muscle group location markers are made of fluorescent material.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] For non-medical personnel, the glove body in this solution features clear muscle group location markings and electrical stimulation site markings. Compared to existing technologies, users do not need professional medical knowledge to determine the correct electrode placement. For example, the electrical stimulation site markings use a composite positioning mark consisting of concentric circular indicator lines and cross-shaped openings, allowing ordinary users to easily find the correct stimulation site. In contrast, existing small home-use electrical stimulation devices lack such intuitive positioning markings, making accurate operation difficult for non-medical personnel. The glove body in this solution employs adjustable fixing components, such as adjustable straps or buckles, to facilitate use by patients of different body types. Existing electrical stimulation devices may lack such convenient fixing methods, potentially leading to electrode misalignment during use. In existing technologies, the difficulty in positioning small home-use electrical stimulation devices often requires assistance from medical personnel, increasing their workload. The glove body in this solution, through its unique markings, allows patients or their families to operate the device independently, reducing the workload of medical personnel.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0031] This utility model provides an upper limb electrical stimulation-assisted positioning glove, which is described in reference to... Figures 1-5 ,include:

[0032] The glove body 1 adopts a wearable flexible sleeve structure that extends from the metacarpophalangeal joint to the shoulder joint. The area corresponding to the metacarpophalangeal joint is provided with a fabric connecting part 8 to achieve a fixed connection at the tiger's mouth. The area corresponding to the palm of the glove body 1 is provided with a finger sleeve structure for the fingers to pass through.

[0033] Fixing component 2 is used to fit the glove body 1 to the limb to prevent slippage and achieve positioning.

[0034] Muscle group location marker 3, drawn on the glove body 1, is used to identify the location of muscle groups; and

[0035] Electrical stimulation site marking 4 is marked on the glove body 1 to mark commonly used electrical stimulation sites. Electrical stimulation site marking 4 includes a composite positioning mark consisting of concentric circular indicator lines and cross-shaped openings, used to mark the stimulation position.

[0036] Specifically, the flexible glove structure is made of lightweight, breathable fabric (such as a nylon and spandex blend) and covers the area from the metacarpophalangeal joint to the shoulder joint, ensuring wearability and flexibility. At the metacarpophalangeal joint, the web area is secured via a fabric connector 8 (also made of lightweight, breathable fabric), enhancing the fit between the glove and the limb. The fixing component 2 can use adjustable straps or buckles to wrap around the forearm and upper arm, secured with Velcro or snaps to ensure the glove does not easily slip off during exercise or electrical stimulation. Muscle group location markers 3 are printed or embroidered on the outer surface of the glove body 1, marking the positions of major muscle groups (such as deltoid 31, biceps brachii 32, brachioradialis 33, triceps brachii 34, extensor muscles 35, etc.) to help quickly locate target muscles. The electrical stimulation site markers 4 use a composite positioning marker consisting of concentric circular indicator lines and cross-shaped openings to ensure accurate marking of stimulation sites. An electrostimulation module with a built-in low-frequency pulse generator can be used, with the electrode positions corresponding to the electrostimulation site markings 4. Current is transmitted to the target muscle through surface electrodes (such as silver fiber electrodes or hydrogel electrodes). An optional wireless communication module (such as Bluetooth) can be added to connect to an external controller or APP, enabling real-time adjustment of stimulation parameters (frequency, intensity, mode). The glove body 1 of this application solves the problem of difficult positioning and promotion of existing small home-use electrostimulation devices through unique markings (muscle group positions and electrostimulation site markings 4). It effectively addresses practical problems in upper limb dysfunction rehabilitation, reducing the workload of medical personnel and facilitating operation for non-medical personnel. It has significant value in actual upper limb functional rehabilitation scenarios, improving the convenience and feasibility of patients using electrostimulation devices for rehabilitation.

[0037] The fixation components include a first restraint band segment 21 and a second restraint band segment 22. The proximal end of the first restraint band segment 21 is connected to the posterior region of the first shoulder of the glove body 1 (corresponding to the inferior angle of the left scapula). The distal end of the first restraint band segment 21 extends from above the contralateral shoulder joint (right acromion) to the anterior region of the second shoulder (right infraclavicular fossa) for fixation. The second restraint band segment 22 is arranged in a mirror-symmetrical manner with the first restraint band segment 21, with its proximal end connected to the posterior region of the second shoulder and its distal end extending to the anterior region of the first shoulder. The first restraint band segment 21 and the second restraint band segment 22 are made of elastic and breathable fabric (such as Lycra fiber or medical-grade spandex), with a width of 5-8 cm. Through a cross-fixation of both shoulders, they disperse the shear force generated by muscle contraction during electrical stimulation, reducing the risk of shoulder dislocation.

[0038] Both the first restraint strap segment 21 and the second restraint strap segment 22 are equipped with length adjustment buckles 5 for adjusting the length. They are bidirectional buckles or sliding rail adjusters, installed on the outside of the restraint strap segment, and can be adjusted within a range of 30-50cm to accommodate patients with different shoulder widths.

[0039] A fixing buckle 6 is provided between the first restraint strap segment 21 and the second restraint strap segment 22. A transverse fixing buckle 6 (such as a Velcro or snap fastener) is provided on the inner side of the restraint strap segment (near the torso) for secondary fixation after the restraint strap segments cross, to prevent slippage.

[0040] The first restraint strap segment 21, the second restraint strap segment 22 and the glove body 1 are provided with 6 detachable fixing buckles at the intersection of the shoulder blade area. The 6 detachable fixing buckles include a plug-in connector composed of a male buckle and a female buckle. The male buckle is a protruding plug that is embedded in a reserved groove on the inner side of the shoulder of the glove body 1 and is made of medical-grade ABS plastic. The female buckle is a slot structure located on the inner side of the restraint strap segment and is quickly inserted and removed by a spring plate, supporting one-handed operation.

[0041] The diameter of the circular indicator line is adapted to the standard electrode patch size. The appropriate diameter ratio ensures that the electrode patch can be accurately placed in the indicator area during use, thereby improving the effectiveness of the electrode patch.

[0042] The glove body 1 has three clinically adaptable configurations: left limb applicable, right limb applicable, and bilateral limb applicable. Each configuration is selectively configured according to the affected limb side of the hemiplegic patient. Patients with different limb sides have differences in muscle strength and motor function. Therefore, by providing gloves with different configurations, the specific needs of patients can be met in a targeted manner, improving the effectiveness of rehabilitation treatment. For left limb applicable and right limb applicable gloves, the fixing component structure of this embodiment can be used for fixation, or other Velcro or strap structures can be used for fixation.

[0043] The inner layer of the glove body 1 is made of sweat-absorbing and breathable cotton material. During glove use, hands will sweat, and the cotton material absorbs sweat and keeps the skin dry, while its excellent breathability helps the skin breathe. The outer layer of the glove body 1 is made of abrasion-resistant and waterproof material. Abrasion resistance prevents the glove from being easily worn down during daily use or rehabilitation training, while waterproofing prevents the glove from getting wet and affecting its function and lifespan.

[0044] The muscle group location marker 3 is made of fluorescent material. By utilizing the characteristic that fluorescent material can emit bright fluorescence under specific lighting conditions, the location of muscle groups can be more clearly and accurately located, which helps to improve the accuracy of rehabilitation training and the efficiency of medical examinations.

[0045] Implementation principle: When wearing the glove, place the main body 1 on the affected limb and adjust the finger cots to the base of the fingers; cross the first and second restraint strap segments 22 to form an "X" shape covering the shoulder joint; fix the length of the restraint strap segments with the length adjustment buckle 5 to ensure a close fit without any gaps in the scapular area; use the transverse fixing buckle 6 to lock the restraint strap segments, and finally lock the restraint straps to the glove main body 1 with the plug-in connector. According to the muscle group location markings 3 on the outer surface of the glove main body 1, quickly locate the target muscles to be electrically stimulated, such as the deltoid 31, biceps brachii 32, brachioradialis 33, triceps brachii 34, extensor muscles 35, etc.; refer to the electrical stimulation site markings 4 (a composite positioning marking consisting of concentric circular indicator lines and cross-shaped openings), accurately place the electrode pads on the marked stimulation sites, ensuring that the electrode positions correspond to the electrical stimulation site markings 4.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
