Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a glove for Parkinson's patients. Background Technology

[0002] Parkinson's disease is a common neurodegenerative disease characterized by the gradual loss of dopaminergic neurons in the brain, leading to motor dysfunction and a range of non-motor symptoms. The 2020 "Chinese Guidelines for the Treatment of Parkinson's Disease (Fourth Edition)" clearly states that the number of Parkinson's patients in my country will rise from 1.99 million in 2005 to 5 million in 2030, accounting for almost half of the global Parkinson's disease population. Clinical diagnosis of Parkinson's disease often relies on assessment scales such as the MDS-UPDRS (Movement Disorder Society-Unified Parkinson's Disease Rating Scale) to quantify the severity of symptoms. This scale consists of four subscales, with the third subscale, motor function assessment, often susceptible to influence from physician subjectivity and patient emotions, posing challenges to diagnosis and assessment of rehabilitation outcomes.

[0003] Parkinson's disease patients often experience hand symptoms such as tremor (including resting tremor and pill-rolling tremor), rigidity, and bradykinesia. Smart wearable devices are currently the mainstream auxiliary diagnostic equipment, commonly including inertial sensing devices (gyroscopes, etc.), fingertip pressure sensors, or single-core fiber Bragg gratings to capture finger flexion. However, these devices all have significant limitations. For example, Chinese patent CN202311543974 discloses an invention entitled "Intelligent Screening and Assessment System for Parkinson's Disease Based on Multi-Data Driven Technology," whose sensors integrate accelerometers, pressure sensors, and electromyography sensors; currently, application number 2017212... Chinese utility model patent 01427.3 discloses a defibrillation smart glove. This defibrillation smart glove applies a reverse vibration force to the wearer's fingers, which is opposite to the direction of finger tremor. This can suppress finger tremor to a certain extent, reduce the amplitude of finger tremor, and alleviate the inconvenience caused by finger tremor to the wearer's daily life. However, the electromyography sensor and the vibration module need to be in close contact with the skin to better collect electromyography signals and achieve the effect of the vibration module in suppressing finger tremor and reducing the amplitude of finger tremor. The existing glove body is of a fixed size and is not suitable for different sizes of hands, so its applicability is not strong enough. Utility Model Content

One fixing ring 2 is provided on each finger joint. The winding mechanism 6 tightens the pull cord 5 during operation. The pull cord 5 tightens the glove body 1 inside the fixing ring 2, ensuring close contact between the EMG sensor and the vibration module with the skin, regardless of hand size. This allows for better acquisition of EMG signals, and the close contact between the vibration module and the skin fully utilizes the vibration effect, thereby suppressing finger tremor, reducing the amplitude of finger tremors, and alleviating the inconvenience caused by finger tremors in the wearer's daily life.

[0031] Example 2, refer to Figures 1-9 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

One end of the pull rope 5 is fixedly connected to the fixed block 22, and the pull rope 5 passes through the through hole 23 and the sleeve 4.

[0033] In this preferred embodiment, the sleeve 4 protects the pull rope 5, preventing it from being exposed and from tangling together. The fixing ring 2 is made of flexible plastic or rubber, and the pull rope 5 is wrapped around the inner wall of the annular groove 21. When the pull rope 5 is pulled, the glove body 1 inside the fixing ring 2 is tightened, so that the electromyography sensor and the vibration module are in close contact with the skin.

[0034] Reference Figure 4 The winding mechanism 6 includes a housing 61, a first rotating shaft 62, a second rotating shaft 63, a first gear 64, a second gear 65, and a winding drum 66.

[0040] Reference Figure 7 The outer wall of the fixed ring 2 is fixedly connected to the locking mechanism 7, which is used to lock the pull rope 5.

[0041] The locking mechanism 7 includes a base 71 and a cover plate 72. The base 71 is hinged to the cover plate 72. A first guide groove 711 is provided on the base 71, and a second guide groove 721 is provided on the cover plate 72.

[0042] In this preferred embodiment, after the cover plate 72 is closed, the first guide groove 711 and the second guide groove 721 squeeze the pull rope 5 to position the pull rope 5, preventing the pull rope 5 in the fixing ring 2 from becoming loose, which would result in the electromyography sensor and vibration module not making close contact with the skin.

[0043] Reference Figure 7 The inner walls of the first guide groove 711 and the second guide groove 721 are respectively fixedly connected to the conical teeth 73, and multiple conical teeth 73 are provided.

[0044] In this preferred embodiment, after the cover plate 72 is closed, the conical teeth 73 in the first guide groove 711 and the second guide groove 721 squeeze the pull rope 5, further positioning the pull rope 5 and locking the pull rope 5 to prevent the pull rope 5 in the fixing ring 2 from loosening, which would result in the electromyography sensor and vibration module not making close contact with the skin.

The limiting rod 725 slides through the cover plate 72, and the other end of the limiting rod 725 is slidably connected to the slot 712.

[0046] In this preferred embodiment, the slider 723 is moved by the elastic force of the second spring 724. The slider 723 drives the limiting rod 725 to move. After the limiting rod 725 is inserted into the slot 712, it can lock the positions of the base 71 and the cover plate 72. At this time, the cover plate 72 cannot be opened. The conical teeth 73 in the first guide groove 711 and the second guide groove 721 squeeze the pull rope 5, further positioning the pull rope 5 and locking it to prevent the pull rope 5 in the fixing ring 2 from loosening, which would cause the electromyography sensor and vibration module to not make tight contact with the skin. The other end of the limiting rod 725 gradually tapers to facilitate insertion into the slot 712.

[0047] Reference Figure 9 The slider 723 is fixedly connected to the actuating block 74, and the actuating block 74 is slidably connected to the inner wall of the limiting groove 726 opened on the cover plate 72.
