Description

Technical Field

[0001] This utility model relates to the field of sensory rehabilitation training technology, specifically, it is a training device for sensory rehabilitation. Background Technology

[0002] Approximately 50-80% of stroke patients experience varying degrees of sensory dysfunction, including tactile impairment (inability to perceive light touch, pressure, and temperature) and proprioceptive impairment (difficulty perceiving the position and movement of their own limbs, and inability to perform fine motor skills). These sensory dysfunctions significantly impact patients' daily lives, rehabilitation progress, and psychological state. Post-stroke sensory rehabilitation can promote neuroplasticity, stimulate the reconnection of neurons in the brain, improve daily living activities, enhance motor function recovery (sensory and motor functions are interconnected; the recovery of sensory function provides a foundation for motor function rehabilitation, promoting overall functional improvement), and improve mental health. Therefore, early sensory intervention and rehabilitation training are essential.

[0003] A Chinese patent, CN109939324B, discloses a limb mirror therapy device based on a multimodal sensory rehabilitation glove. The device includes a mirror therapy box and rehabilitation gloves. The mirror therapy box comprises a box body, a partition dividing the box body into a left and right box body, multiple cameras disposed within the box body, a lighting device disposed within the box body, and a display screen disposed above the box body. The multimodal sensory rehabilitation gloves provide vibration, vision, and hearing multimodal sensory therapy for patients, stimulating the brain's active participation in rehabilitation training through somatic sensory signals.

[0004] Considering the excessive complexity of existing sensory rehabilitation devices, and in order to reduce costs, a Chinese patent (CN203244557U) has been disclosed, proposing a sensory rehabilitation training system integrating tactile, temperature, and vibration stimulation. This system addresses the problems of large size, poor training effect, and high cost associated with existing sensory rehabilitation training devices. The sensory rehabilitation training system includes a central processing unit with a built-in voice recognition chip, and a sensory training device, a temperature sensor, and a feedback device connected to the central processing unit; the temperature sensor is connected to the sensory training device.

[0005] However, the patent with authorization announcement number CN203244557U still has the problem of high cost. In addition, the setting of temperature sensor and feedback device requires the configuration of central processing unit with built-in voice recognition chip, which makes the cost still high. Once the temperature sensor is damaged, it needs to be replaced and the equipment needs to be repaired, which increases the repair and maintenance costs. Utility Model Content

[0014] Furthermore, the ball bearing receiving groove is connected to the rolling start end of all the track grooves, and the bottom of the ball bearing receiving groove is lower than the bottom of the track groove.

[0015] Furthermore, the ball bearing receiving groove is located at the center of the upper surface of the main body, and the rolling end point of the track groove is close to or exactly at the outer edge of the main body.

[0016] Furthermore, the track groove extends in a serpentine shape.

[0017] Furthermore, the end of the track groove is threaded with a limiting screw for defining the position of the end of the ball's rolling.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. During the sensory rehabilitation process for stroke patients, patients can continuously touch the tactile module, cold module, and heat module with their hands, and comprehensively utilize the tactile module (mainly corresponding to touch and pain sensation), the cold module (corresponding to temperature sensation), and the heat module (corresponding to temperature sensation) to stimulate the patient's superficial sensation (superficial sensation includes pain sensation, temperature sensation, and touch sensation), thus helping to rehabilitate the patient's superficial sensation.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-3 The first embodiment shown provides a training device for sensory rehabilitation, specifically for hand sensory rehabilitation activities in stroke patients, comprising:

[0028] The main body 1 is designed as a rectangular plate and is made of a lightweight material. Its overall size is similar to that of a common laptop computer. It can be carried by a single person and does not take up much space. The upper surface of the main body 1 has several positioning slots 101. When in use, the main body 1 can be placed directly on a table or other platform.

[0029] At least two tactile modules 2 with different surface roughness are provided for patients to touch during use and are used for tactile and pain rehabilitation. They can also be of different hardness. The tactile modules 2 can be interchangeably inserted into (placed) in the corresponding positioning slots 101. The tactile modules 2 can be items with different surface roughness, such as steel wool, scouring pads, sandpaper, velvet, linen, etc., which can be flexibly selected according to needs.

[0030] At least one cold module 3 is provided for the patient's hand to touch during use, for temperature sensation rehabilitation, and provides cold stimulation. The cold module 3 can be replaced and inserted into the corresponding positioning slot 101. The cold module 3 can be a rectangular heat-conducting metal sheet that can be soaked in ice water for a period of time until it cools down. Then the cold module 3 is removed and placed in the corresponding positioning slot 101. The degree of coldness of the cold module 3 can be flexibly controlled by medical staff.

[0031] At least one thermal module 4 is provided for the patient's hand to touch during use, for temperature sensation rehabilitation, and to provide thermal stimulation. The thermal module 4 can be replaced and inserted into the corresponding positioning slot 101. The thermal module 4 can be a rectangular heat-conducting metal sheet. It can be soaked in hot water for a period of time until it becomes hot, and then the thermal module 4 can be removed and placed in the corresponding positioning slot 101. The heat of the thermal module 4 can be flexibly controlled by medical staff.

[0032] Several balls 5 of different diameters are used to stimulate the patient's combined deep and superficial sensations. The balls 5 can be hard balls, such as glass balls, stainless steel balls, or hard plastic balls, or soft balls, such as rubber balls or silicone balls. The upper surface of the main body 1 has several rectangular track grooves 102 that match the balls 5 one by one. The diameter of the balls 5 is different, and the depth and width of the corresponding track grooves 102 are also different. The track grooves 102 are set as strips (curved or straight). The balls 5 are rolled in the corresponding track grooves 102. The diameter of the balls 5 is smaller than and close to the width (and depth) of the corresponding track grooves 102. That is, balls 5 of different diameters are configured with track grooves 102 of different widths.

[0033] According to academic definitions, superficial sensation includes pain, temperature, and touch. During sensory rehabilitation for stroke patients, they can continuously touch tactile module 2, cold module 3, and heat module 4, comprehensively utilizing tactile module 2 (primarily corresponding to touch and pain), cold module 3 (corresponding to temperature), and heat module 4 (corresponding to temperature) to stimulate their superficial sensations. Tactile module 2, cold module 3, and heat module 4 can all be replaced as needed.

[0034] The patient uses their hand to move different sized balls 5 within the corresponding track groove 102, thereby creating a ball movement pattern to stimulate the patient's combined deep and superficial sensations.

[0035] The principle of the above components is explained as follows:

[0036] When in use, place the main body 1 on a table and let the patient freely touch the tactile modules 2 with different textures and hardness, as well as the rollers 5 of different sizes, which helps to restore sensory function; then the patient pushes the rollers 5 of different sizes to roll in the corresponding track grooves 102 to perform simple hand movements.

[0037] The operation of the tactile module 2 and the push ball 5 can be completed independently by the patient; when accompanied by family members, the cold module 3 and the hot module 4 can be used to provide cold and hot stimulation to the patient's hands to promote the recovery of the patient's temperature sensation function.

[0038] In order to facilitate the collection of all the balls 5, a ball receiving groove 103 is provided on the upper surface of the main body 1 for placing all the balls 5. Before use, all the balls 5 can be collected in the ball receiving groove 103.

[0039] The aforementioned ball receiving groove 103 is connected to the rolling start end of all the track grooves 102, and the bottom of the ball receiving groove 103 is 2-10mm lower than the bottom of the track groove 102 to prevent the ball 5 in the ball receiving groove 103 from rolling into the track groove 102. When in use, with the help of a doctor or caregiver, the ball 5 can be directly moved to the rolling start end of the corresponding track groove 102 with a finger, so that the patient can move the ball 5 by hand and make the ball 5 roll in the corresponding track groove 102.

[0040] As a structural optimization scheme, the ball receiving groove 103 is located at the center of the upper surface of the main body seat 1, and the rolling end point of the track groove 102 is close to or at the outer edge of the main body seat 1.

[0041] To increase the variability of the rolling trajectory of the ball 5, the aforementioned track groove 102 extends in a serpentine pattern (i.e., a continuous S-curve) to better stimulate the patient's sensory rehabilitation process.

[0042] In the first embodiment, the main body 1 is made of wood, and the positioning groove 101 and ball bearing receiving groove 103 on the surface can be directly machined with a cutting tool.

[0043] like Figure 4 The illustration presents a second embodiment, which differs from the first embodiment in that:

[0044] The main body 1 is designed as a one-piece injection-molded plastic structure to facilitate mass production.

[0045] To ensure the support performance and structural strength of the main body base 1, the bottom surface of the main body base 1 may have a central support protrusion 104 and an outer support protrusion 105.

[0046] The outer support protrusion 105 extends around the bottom edge of the main body 1 and protrudes downward based on the bottom surface of the main body 1, forming the main bottom support structure of the main body 1.

[0047] The central support protrusion 104 is located directly below the ball receiving groove 103. The central support protrusion 104 extends along the contour of the ball receiving groove 103 and protrudes downward based on the bottom surface of the main body 1 in order to better support all the balls 5.

[0048] like Figure 5 The third embodiment is presented, which differs from the first embodiment in that:

[0049] The end of the track groove 102 is threaded with a limiting screw 6 for limiting the position of the end of the rolling of the ball 5, preventing the ball 5 from slipping out of the main body seat 1. In this embodiment, the main body seat 1 can be made of wood or plastic and can be combined with the second embodiment.
