Description

Technical Field

[0001] This invention belongs to the field of electrical stimulation device technology, specifically relating to a wearable device for children that uses ASD mid-frequency electrical stimulation targeting the Neiguan acupoint. Background Technology

[0002] Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder. Clinical studies have shown that mid-frequency electrical stimulation of the Neiguan acupoint (located on the palmar side of the forearm, 2 inches above the wrist crease, between the two tendons), with a length of 1 inch roughly the width of a child's thumb joint, can regulate the secretion of neurotransmitters in the central nervous system and improve the social interaction, emotional control, and attention span of children with ASD. This provides an effective non-pharmacological intervention pathway for ASD treatment. Considering the physiological characteristics of children, such electrical stimulation devices must balance precise acupoint location, wearing comfort, and ease of operation. The core technological bottleneck lies in the coordinated design of the acupoint positioning mechanical structure and the electrical stimulation execution end.

[0003] Currently, existing wearable devices for targeting acupoints with intermediate-frequency electrical stimulation are typically manually positioned. These devices all have significant drawbacks in applications involving children. The core structure of these manually positioned devices is usually a combination of fixed electrode pads and a wristband. Users (parents or medical professionals) manually adjust the device's position according to the child's wrist size by marking graduations and positioning indicators on the wristband or the device itself, ensuring the electrode pads are aligned with the Neiguan acupoint. The positioning accuracy of this type of device relies entirely on manual judgment and is greatly affected by the child's wrist movement, changes in body position, and the user's experience. This easily leads to the electrode pads deviating from the Neiguan acupoint, resulting in a decrease in the therapeutic effect of the electrical stimulation. Summary of the Invention

[0004] The purpose of this invention is to provide a wearable ASD mid-frequency electrical stimulation device for children that targets the Neiguan acupoint, aiming to solve the problem that the positioning accuracy of existing manually positioned devices depends entirely on human judgment, which easily leads to the electrode pads deviating from the Neiguan acupoint.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-10 The present invention provides the following technical solution: ASD mid-frequency electrical stimulation wearable device for children targeting Neiguan acupoint, including: a massager body 1, with wrist straps 10 installed at intervals at the front and rear ends of the massager body 1, the wrist straps 10 can be worn on the arm, and the wrist straps 10 located at the upper end of the massager body 1 need to be sleeved on the wrist of the arm.

[0021] A positioning plate 11 is installed on the outside of the massager body. The positioning plate 11 is used to locate the child patient's thumb. The Neiguan acupoint is located about 2 inches from the wrist line of the human arm. 1 inch is about the width of the child's thumb joint. A measuring plate 12 is slidably installed on the outside of the massager body 1. The child patient inserts his thumb joint between the measuring plate 12 and the positioning plate 11. The distance that the measuring plate 12 moves is the width of the child patient's thumb joint (about 1 inch).

[0022] The massager body 1 is equipped with a drive unit for pushing the measuring plate 12 to slide up and down relative to the positioning plate 11. The drive unit includes a pressing plate 13 that is slidably disposed inside the massager body 1. The pressing plate 13 can slide left and right inside the massager body 1. The massager body 1 has a groove for the pressing plate 13 to slide. The end of the pressing plate 13 that extends out of the massager body 1 has an arc-shaped opening. Children can place their thumb fingerprint area at the arc-shaped opening and press the pressing plate 13 inward to push the measuring plate 12 to slide on the outer wall of the massager body 1.

[0023] The massager body 1 is equipped with a pushing component. When the pressing plate 13 moves into the massager body 1, the pushing component can push the measuring plate 12 to move downward relative to the positioning plate 11. The pushing component includes a drive rack 51, a drive gear 52, a drive screw 53, a drive nut 54, and an L-shaped plate 55. The drive rack 51 is installed at the end of the pressing plate 13 facing the positioning plate 11.

[0024] The drive gear 52 is rotatably installed inside the massager body 1 and meshes with the drive rack 51. The L-shaped plate 55 is slidably installed inside the massager body 1. One end of the L-shaped plate 55 extending outside the massager body 1 is connected to the measuring plate 12. The drive nut 54 is rotatably installed inside the massager body 1. The drive screw 53 is rotatably installed inside the massager body 1 and is connected to the drive gear 52. The drive screw 53 is threadedly connected to the drive nut 54.

[0025] Please see Figure 1-6 Press the pressing plate 13 inward, and the pressing plate 13 moves into the massager body 1. The pressing plate 13 drives the drive rack 51 to move into the massager body 1. The drive rack 51 drives the drive gear 52 to rotate. The drive gear 52 drives the drive screw 53 to rotate. The drive screw 53 drives the L-shaped plate 55 to move through the drive nut 54. The massager body 1 has an L-shaped moving slide groove. The L-shaped plate 55 moves inside the L-shaped moving slide groove. The L-shaped plate 55 drives the measuring plate 12 to move.

[0026] The bottom of the massager body 1 is provided with a T-shaped groove, and a T-shaped plate 2 is slidably arranged in the T-shaped groove. The massager body 1 is provided with a transmission mechanism. When the pressing plate 13 moves into the massager body 1, the pushing component can drive the T-shaped plate 2 to move downward relative to the positioning plate 11 through the transmission mechanism. The moving distance of the T-shaped plate 2 is twice the moving distance of the measuring plate 12.

[0027] The transmission mechanism includes a transmission gear 56 rotatably disposed inside the massager body 1. The transmission gear 56 meshes with the drive gear 52. The number of teeth of the transmission gear 56 is half that of the drive gear 52, so that the number of rotations of the transmission gear 56 is twice that of the drive gear 52.

[0028] The transmission gear 56 is equipped with a driving component for moving the T-shaped plate 2. The driving component includes a transmission screw 24, a transmission nut 25, and an L-shaped moving plate 26. The transmission screw 24 is rotatably installed inside the massager body 1 and is connected to the transmission gear 56. The L-shaped moving plate 26 is slidably installed inside the massager body 1. The transmission nut 25 is rotatably installed on the L-shaped moving plate 26 and is threadedly connected to the transmission screw 24.

[0029] The transmission gear 56 drives the transmission screw 24 to rotate, and the transmission screw 24 drives the L-shaped moving plate 26 to move through the transmission nut 25. The L-shaped moving plate 26 is connected to the T-shaped plate 2, which in turn drives the T-shaped plate 2 to move. Since the number of teeth of the transmission gear 56 is half that of the drive gear 52, and its number of rotations is twice that of the drive gear 52, the moving distance of the L-shaped moving plate 26 is twice that of the measuring plate 12 (i.e., the width of the two thumb joints of the child patient).

[0030] Please see Figure 5 and Figure 6 Electrode pads 21 are installed at the bottom of the T-shaped plate 2. Electrode pads 21 can provide electrical stimulation massage to the patient's acupoints. This is existing technology and will not be described in detail here. The massager body 1 has a control panel inside. Flexible conductive layers 3 for measuring human skin resistance are arranged at intervals on the left and right sides of the bottom of the massager body 1. Electrode blocks 31 are arranged in an array at the end of the flexible conductive layer 3 facing the skin. The flexible conductive layer 3 is connected to the control panel for signal transmission.

[0031] The flexible conductive layer 3 can detect changes in the resistance of the patient's skin. Since the skin resistance at acupoints is usually lower than that of the surrounding non-acupoint skin areas, the flexible conductive layer 3 can accurately locate the Neiguan acupoint. The massager body 1 has a moving groove inside, and a power supply device 4 is slidably installed inside the moving groove. The power supply device 4 is connected to the control panel. After the flexible conductive layer 3 detects the accurate location of the Neiguan acupoint, it transmits the signal to the control panel. The control panel controls the power supply device 4 to move to the accurate location of the Neiguan acupoint.

[0032] The bottom of the massager body 1 has a receiving groove, and compression springs 15 are arranged at intervals inside the receiving groove. The flexible conductive layer 3 is slidably disposed inside the receiving groove. The compression springs 15 are connected to the flexible conductive layer 3. After the electrode 21 moves to the accurate position of the Neiguan acupoint, the flexible conductive layer 3 can be compressed and enter the receiving groove. At the same time, under the action of the compression springs 15, the electrode 21 can be made to fit closely to the patient's skin.

[0033] Please see Figure 1-5 The power supply device 4 has a first magnetic terminal 22 at one end facing the T-shaped plate 2, and a second magnetic terminal 23 is provided on the T-shaped plate 2. A battery is installed inside the massager body 1, and the battery is connected to the first magnetic terminal 22 via a wire. The first magnetic terminal 22 is a male connector, and the second magnetic terminal 23 is a female connector. The first magnetic terminal 22 can attract the second magnetic terminal 23 (this is prior art). The first magnetic terminal 22 generates magnetism when energized. The second magnetic terminal 23 is a permanent magnet. A circuit can be formed between the battery and the electrode plate 21 through the first magnetic terminal 22 and the second magnetic terminal 23.

[0034] The electrode pad 21 is connected to the control panel. The control panel receives user operation commands (such as mode selection and intensity adjustment), and converts the commands into electrical stimulation signals of specific frequency and amplitude through the control chip. These signals are then transmitted to the electrode pad 21, which drives the electrode pad 21 to output massage stimulation to the human body. This is existing technology and will not be described in detail here.

[0035] The power supply device 4 includes a moving rack 41, a moving gear 42, and a drive motor 43. The moving rack 41 is slidably installed inside the moving groove, and the moving gear 42 is rotatably installed inside the massager body 1. The moving gear 42 meshes with the moving rack 41. The drive motor 43 is installed inside the massager body 1, and the output end of the drive motor 43 is connected to the moving gear 42. The drive motor 43 is connected to the control panel.

[0036] Please continue reading. Figure 5 and Figure 6 The massager body 1 has a rectangular groove at the bottom. The moving rack 41 is slidably set inside the rectangular groove. The rectangular groove is connected to the T-shaped groove. The drive motor 43 drives the moving gear 42 to rotate. The moving gear 42 drives the moving rack 41 to move.

[0037] A limiting post 27 is installed inside the T-shaped groove. An inverted U-shaped plate 271 is slidably mounted on the limiting post 27. An L-shaped moving plate 26 is connected to the inverted U-shaped plate 271. A T-shaped plate 2 is slidably mounted on the limiting post 27. The limiting post 27 limits the inverted U-shaped plate 271 and the T-shaped plate 2, so that the T-shaped plate 2 and the inverted U-shaped plate 271 can slide smoothly.

[0038] A reset spring 14 is provided between the inverted U-shaped plate 271 and the T-shaped plate 2. The first magnetic terminal 22 attracts the second magnetic terminal 23 to move, which can stretch the reset spring 14. After the control panel de-energizes the first magnetic terminal 22, the first magnetic terminal 22 and the second magnetic terminal 23 no longer attract each other. Under the action of the reset spring 14, the T-shaped plate 2 can be reset.

[0039] Right-angled triangular slots 16 are spaced apart on the left and right sides of the pressing plate 13. A drive groove is provided inside the massager body 1. The pressing plate 13 is slidably disposed inside the drive groove. A drive spring 17 is provided inside the drive groove. The drive spring 17 is connected to the pressing plate 13. A through groove is provided in the massager body 1 that communicates with the drive groove. A T-shaped block 18 is slidably disposed inside the through groove. A right-angled block 19 that matches the right-angled triangular slots 16 is provided at the bottom of the T-shaped block 18.

[0040] When the pressing plate 13 slides into the massager body 1, the right-angled triangular slot 16 and the right-angled block 19 can push the T-shaped block 18 to move upward inside the through slot. The right-angled triangular slot 16 and the right-angled block 19 enable the pressing plate 13 to move in one direction. Pushing the T-shaped block 18 upward causes the right-angled block 19 to disengage from the right-angled triangular slot 16. At the same time, the pressing plate 13 is reset under the action of the drive spring 17.

[0041] Please see Figure 1-10 Working principle: When using, first place the fingerprint area of ​​the child patient's thumb on the arc-shaped opening of the pressing plate 13, at which point one end of the child patient's thumb is aligned with the positioning plate 11; then press the pressing plate 13 inward, the pressing plate 13 will drive the drive rack 51 to move into the massager body 1, the drive rack 51 will then drive the drive gear 52 to rotate, the drive gear 52 will then drive the drive screw 53 to rotate; the drive screw 53 drives the L-shaped plate 55 to move through the drive nut 54, and the L-shaped plate 55 will drive the measuring plate 12 to move; when the end of the measuring plate 12 facing the positioning plate 11 is aligned with the other end of the child patient's thumb, release the pressing plate 13.

[0042] At this point, the distance between the measuring plate 12 and the positioning plate 11 is approximately the width of the child patient's thumb joint (about 1 inch). When the drive gear 52 rotates, it drives the transmission gear 56 to rotate synchronously. The transmission gear 56 then drives the transmission screw 24 to rotate, and the transmission screw 24 drives the L-shaped moving plate 26 to move through the transmission nut 25. Since the L-shaped moving plate 26 is connected to the T-shaped plate 2, it will synchronously drive the T-shaped plate 2 to move. Furthermore, because the number of teeth on the transmission gear 56 is half that of the drive gear 52, and its number of rotations is twice that of the drive gear 52, the moving distance of the L-shaped moving plate 26 is twice that of the measuring plate 12 (i.e., the width of the patient's two thumb joints, about 2 inches).

[0043] The T-shaped plate 2 moves the electrode 21 to a position about 2 inches away from the positioning plate 11. Then, the massager body 1 is worn on the patient's arm through the wrist strap connecting strap 10. The wrist strap connecting strap 10 located at the upper end of the massager body 1 needs to be fitted on the wrist line of the arm. At this time, the position of the electrode 21 is about 2 inches above the wrist line of the arm.

[0044] When the massager body 1 is activated, the flexible conductive layer 3 detects the change in resistance on the human skin and accurately locates the Neiguan acupoint. The control panel controls the drive motor 43 to rotate, which in turn drives the moving gear 42 to rotate. The moving gear 42 then drives the moving rack 41 to move. The first magnetic terminal 22 attracts the second magnetic terminal 23 to move towards the Neiguan acupoint, thereby moving the electrode 21 to the accurate position and precisely locating the acupoint.

[0045] After use, disconnect the circuit. The first magnetic terminal 22 and the second magnetic terminal 23 will no longer attract each other. Under the action of the reset spring 14, the T-shaped plate 2 can be reset. Push the T-shaped block 18 upward so that the right-angle block 19 is disengaged from the right-angled triangular slot 16. At the same time, under the action of the drive spring 17, the pressing plate 13 is reset. Meanwhile, the transmission gear 56 and the drive gear 52 rotate in opposite directions, driving the measuring plate 12 and the T-shaped plate 2 to reset.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
