[0027] exist Figure 1 and Figure 2In the vest body 1, a drawstring assembly 3 is provided on the side away from the pocket 2 for adjusting the fit of the vest body 1. The drawstring assembly 3 includes a third piece 301 connected to the first piece 101 and the second piece 102. Several through holes 302 are provided at the connection points between the first piece 101 and the third piece 301, and between the second piece 102 and the third piece 301. Drawstrings 303 in a crisscross structure are threaded through these through holes 302. It should be noted that the third piece 301... The material is also a common elastic fabric. The splicing between the third piece 301 and the first piece 101 and the second piece 102 is also done with three-needle five-thread or four-needle six-thread coverstitch. In this embodiment, the vest body 1 has a tie design on the side. There are 7 insertion holes 302 on each side of the tie design. The tie 303 itself is mainly made of polyester. It passes through all the insertion holes 302 alternately to form a cross structure. The fit of the vest can be adjusted by adjusting the tightness of the tie 303.

[0028] Please see Figure 1 The second piece 102 has several embroidered electrodes made of silver-plated yarn corresponding to the Jianjing and Tianzong acupoints on the user's shoulders. The embroidered electrodes are circular in shape and the embroidery stitch type is radial filling of tatamie. A metal bottom buckle 8 that can be connected to the terminal of the electrical stimulation generator 9 is also provided at the center of the embroidered electrode. It should be noted that the conductive electrode is formed by embroidering silver-plated yarn on the main body 1 of the vest. The embroidered electrode covers the Jianjing and Tianzong acupoints on the shoulders. The metal bottom buckle 8 embedded in the center of the embroidered electrode is connected to the terminal of the electrical stimulation generator 9. In this embodiment, there are four embroidered electrodes, that is, four embroidered electrodes are covered on the shoulders of the garment, located at the Jianjing and Tianzong acupoints on the left and right shoulders, respectively, so as to achieve the effect of precise electrical stimulation of acupoints.

[0029] It should also be noted that four embroidered electrodes are set in the second piece 102 of the vest body 1, covering the Jianjing and Tianzong acupoints on the shoulders. These four embroidered electrodes are: Jianjing acupoint 4 on the left shoulder, Tianzong acupoint 5 on the left shoulder, Jianjing acupoint 6 on the right shoulder, and Tianzong acupoint 7 on the right shoulder. The embroidered electrodes are made of silver-plated yarn, are 28mm in size, and use radial fill stitches. This design allows for good conductivity. A metal bottom buckle 8 is then embedded in the center of the embroidered electrode, which connects to the terminal of the electrical stimulation generator 9. Please refer to the actual product for details. Figure 3 ;

[0030] To better relieve shoulder fatigue and pain, it is important to accurately locate the acupoints on the shoulder. For specific acupoint locations, please refer to [the provided text]. Figure 4Based on Traditional Chinese Medicine (TCM) acupoint theory, the Jianjing acupoint is located at the midpoint of the line connecting the Dazhui (GV14) and the acromion. It has the functions of dispelling wind and clearing heat, promoting blood circulation and reducing swelling, and can treat symptoms such as shoulder and back pain, and frozen shoulder. The Tianzong acupoint is located in the scapular region, in the depression at the junction of the lower 1 / 3 and lower 2 / 3 of the line connecting the midpoint of the scapular spine and the inferior angle of the scapula. It has the function of relieving muscle tension and spasms, and is suitable for relieving symptoms such as scapular pain and soft tissue injuries of the shoulder and back. For detailed explanations of acupoints, please refer to [link to relevant information]. Figure 5 The electrical stimulation generator 9 precisely outputs electrical pulses and waveforms with specific parameters to simulate classic techniques in traditional Chinese massage such as "pressing, kneading, pushing, plucking, and grasping," acting on corresponding acupoints and surrounding muscle groups to ultimately relieve muscle fatigue and promote blood circulation. In this embodiment, the electrical stimulation therapy vest uses women's size 160 / 84A as the base size (M), and the position of the embroidered electrodes in commonly used sizes S, M, and L is adjusted according to conventional sizing to suit people of different heights and weights.

[0031] Please see Figure 1 and Figure 6 The electrical stimulation generator 9 includes a housing 901 and circuit components located inside the housing 901. The circuit components include a circuit board installed inside the housing 901 and a control module, a pulse output module, a button module, a display module, a power module, and a charging module mounted on the circuit board. The housing 901 is provided with a display screen 902, a power switch 903, and a charging socket 909 corresponding to the display module, the power module, and the charging module, respectively. The surface of the housing 901 is also provided with an intensity increase control button 904, an intensity decrease control button 905, and a time control button 906. It should be noted that the electrical stimulation generator 9 adopts a modular integrated design, including a control module, an electrical stimulation output module, a button module, a display module, a power module, and a charging module. Each module is electrically connected in sequence through a printed circuit board and encapsulated inside the housing 901. The housing 901 is provided with control buttons, a display screen 902, and a charging socket 909 that are connected to the modules inside the housing 901.

[0032] The control module includes a microcontroller integrated circuit and a pulse signal output amplifier circuit. The pulse signal output amplifier circuit is electrically connected to the pulse output module. The pulse output module extends to form a dual-channel output line that can be fastened to the metal bottom buckle inside the embroidery electrode to form a circuit. The microcontroller integrated circuit is responsible for logic control and parameter calculation. The pulse signal output amplifier circuit amplifies the generated pulse signal and then connects it to the embroidery electrode through the dual-channel output line extended from the pulse output module. It should be noted that the dual-channel output line extends to form a first output line 907 and a second output line 908. The left shoulder Jianjing acupoint embroidery electrode 4, the left shoulder Tianzong acupoint embroidery electrode 5, the right shoulder Jianjing acupoint embroidery electrode 6, and the right shoulder Tianzong acupoint embroidery electrode 7 are respectively fastened to the first output line 907 and the second output line 908 to form a circuit. When in use, simply press the power button to turn on the device and enter the control interface. The intensity and working time of the electrical stimulation can be controlled. The electrical stimulation generator 9 can be placed in the pocket 2 for easy carrying. When the power is depleted, it can be charged by connecting an external power source to the charging port 909. It is convenient, safe and energy-saving to use.

[0033] The second embodiment of the present invention relates to a method for manufacturing a shoulder electrical stimulation therapy vest based on embroidered electrodes, the process of which is as follows: Figure 7 As shown, the specific steps are as follows:

[0034] Step 101: Select common elastic fabric to make the first piece 101, the second piece 102, the third piece 301 and the pocket 2, and then use three-needle five-thread or four-needle six-thread coverstitch to sew the first piece 101 to the third piece 301 and the pocket 2.

[0035] Step 102: Perforation is performed at the connection between the first piece 101 and the third piece 301 and the connection between the second piece 102 and the third piece 301. Then, an overlock machine is used to overlock the armholes, neckline, and hem.

[0036] Step 103: Place two layers of water-soluble lining below the embroidery position of the second piece 102, fix it to the embroidery machine with a magnetic embroidery frame, and then use silver-plated yarn as the bottom and top threads of the embroidery to obtain several embroidery electrodes.

[0037] Specifically, to prevent deformation and skipped stitches on the embroidery electrode surface, two layers of water-soluble lining cloth can be placed under the elastic fabric, and the embroidery can be washed in water after completion.

[0038] More specifically, the silver-plated yarn is made by wrapping pure silver around the surface of a nylon substrate to form a soft silver layer. It is a safe and long-lasting antibacterial fiber product with good spinnability. The fineness of the silver-plated yarn is 70D / 3, and the impedance is 3~5Ω / cm. The embroidery electrode is a circle with a diameter of 28mm. The stitch type of the embroidery electrode is radial filler with tatamie stitch, the stitch length is 4mm, the stitch spacing is 0.5mm, and the needle speed during embroidery is 500~600 stitches / min.

[0039] Step 104: Soak and clean the water-soluble lining fabric at the embroidery position with clean water, then embed the metal bottom buckle 8 into the embroidery electrode, and then thread the tie 303 through the insertion hole 302 in an alternating manner to obtain a physiotherapy vest that can be used for electrical stimulation.

[0040] Furthermore, common elastic fabrics are selected as the front and back panels of the vest body 1, namely the first panel 101 and the second panel 102. Then, the front and back panels, as well as the pocket 2, are sewed together using three-needle five-thread or four-needle six-thread stitching. The sides of the tie design are perforated. The armholes, neckline, and hem are overlocked using an overlock machine. Then, two layers of water-soluble lining are placed below the embroidery position of the vest body 1, and the lining is fixed to the embroidery machine using a magnetic embroidery frame. Silver-plated yarn is used as the bottom and top threads of the embroidery to obtain the embroidery electrodes. The water-soluble lining at the embroidery position is then soaked and cleaned with water. Finally, the metal bottom buckle 8 is embedded into the embroidery electrodes to obtain a therapeutic vest that can be used for electrical stimulation. This technical solution integrates the flexible textile electrodes with the clothing, ensuring good wearing comfort and biocompatibility with human skin.

[0041] In summary, this invention, based on the principles of electrostimulation therapy and traditional Chinese medicine acupoint theory, achieves a balance between efficient shoulder therapy and comfortable use by precisely locating key acupoints on the shoulder and designing targeted core functional structures and manufacturing processes. On one hand, by utilizing the excellent conductivity of silver-plated yarn and embroidery technology, the flexible textile electrode is integrated into the garment, ensuring both good conductivity and stable connection to the terminals of the electrostimulation generator 9. On the other hand, the modularly integrated electrostimulation generator 9, connected to the embroidered electrodes on the left and right shoulders via dual-channel output lines, precisely targets acupoints and surrounding muscle groups, effectively relieving shoulder muscle tension and promoting blood circulation. This improves the overall performance of existing shoulder therapy products, providing a more efficient and comfortable solution for shoulder therapy.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
