DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] See also Figure 1-Figure 8The present invention provides a technical solution: a transcutaneous electrical nerve stimulation therapeutic device, comprising a shell 1, inside which a current generator 2 and an exhaust device 3 are arranged; it also comprises a U-shaped smooth sheet 4, the surface of which is relatively rough; an adhesive layer 5 is arranged on one side of the U-shaped smooth sheet 4, and the adhesive layer 5 is the same as the adhesive layer of double-sided tape, adhesive tape, etc. A protective film is arranged on the side of the adhesive layer 5 away from the U-shaped smooth sheet 4, and by tearing off the protective film, the U-shaped smooth sheet 4 can be bonded to the patient's skin surface through the adhesive layer 5.

[0030] The electrical stimulation therapeutic device also includes an electrode sheet assembly 6, which is used to be adsorbed on the side surface of the U-shaped smooth thin sheet 4 away from the adhesive layer 5; specifically, the electrode patch 66 assembly includes two parallel flexible strips 62, a support block 61 is arranged between the two flexible strips 62, the two flexible strips 62 are symmetrically arranged on both sides of the support block 61, and the two flexible strips 62 are detachably arranged on the support block 61; both flexible strips 62 are provided with a card slot 621, and a matching flexible tube 63 is arranged in the card slot 621, and the flexible tube 63 can be fixed in the card slot 621 by bonding; at the same time, the flexible strip 62 and the flexible tube 63 can be made of silicone or rubber.

[0031] Two suction cups 64 are connected to each of the two flexible tubes 63, and the suction cups 64 are flexible suction cups; the suction cup 64 on each flexible tube 63 is connected to the flexible tube 63, and one end of the flexible tube 63 is closed, and the other end of the flexible tube 63 is connected to the exhaust device 3 through an air guide hose; a gasket 641 is provided on the outside of each suction cup 64, and the gasket 641 and the suction cup 64 adopt an integrally formed structure; since there are two flexible tubes 63, two suction cups 64 are connected to each flexible tube 63, so there are four suction cups 64; the four suction cups 64 are distributed in a circular array, and a support member 65 is placed between the four suction cups 64 distributed in the circular array, and the support member 65 is located between the gasket 641 and the head of the suction cup 64.

[0032] An electrode patch 66 is arranged on the support member 65, and the electrode patch 66 is connected to the current generator 2 through the electrical connection line 21; specifically, the support member 65 includes a coaxially arranged support ring 651 and a support circle 652, the support circle 652 is fixedly arranged on the support ring 651, and the electrode patch 66 is bonded to the support circle 652; the electrode patch 66 adopts a circular structure, and the electrode patch 66 is coaxially arranged on the support circle 652; the support circle 652 can be made of a flexible material, such as rubber or silicone, the diameter of the electrode patch 66 is equal to the diameter of the support circle 652, or the diameter of the electrode is slightly smaller than the diameter of the support circle 652, and in addition, the diameter of the support circle 652 is smaller than the width of the middle opening of the U-shaped smooth sheet 4.

[0033] A through hole 611 is provided in the middle of the support block 61, and the electrical connection line 21 passes through the through hole 611 and the center holes of the support ring 652 and the support ring 651; at the same time, a number of tooth grooves are evenly distributed on both sides of the support block 61, thereby increasing the roughness of the surfaces on both sides of the support block 61, making it easier to hold the support block 61 by hand.

[0034] When the patient is given electrical stimulation treatment, two electrode patches 66 are required to be used, so two electrode patch assemblies 6 are needed. The two electrode patches 66 are respectively connected to the current generator 2 through an electrical connection line 21; two vacuum devices 3 are also arranged inside the shell 1. The vacuum device 3 adopts a vacuum pump 31, and the vacuum pump 31 is provided with two vacuum connection ports. The two vacuum connection ports of the same vacuum pump 31 are respectively connected to the two flexible tubes 63 included in the same electrode patch assembly 6.

[0035] In this embodiment, when the patient is subjected to electrical stimulation treatment, the U-shaped smooth sheet 4 is firstly bonded to the patient's skin surface through the adhesive layer 5, and the two acupuncture points to be treated of the patient are located at the middle opening of the U-shaped smooth sheet 4; the adhesive layer 5 and the U-shaped smooth sheet 4 are in the shape of long strips as a whole, and the adhesive layer 5 has a larger contact with the patient and a longer coverage area, so the sweat, oil, etc. on the patient's skin surface have little effect on the adhesive layer 5; then, by holding and pinching the support block 61 of one of the electrode sheet assemblies 6, the corresponding four suction cups 64 are driven to contact the surface of the U-shaped smooth sheet 4, and the corresponding electrode patch 66 corresponds to the opening position of the U-shaped smooth sheet 4, and the corresponding electrode patch 66 corresponds to one of the patient's acupuncture points, and at this time the electrode patch 66 is close to the surface of the U-shaped smooth sheet 4. The patient's skin is then evacuated through the corresponding vacuum pump 31, so that negative pressure is formed between the corresponding four suction cups 64 and the U-shaped smooth sheet 4, so that the suction cup 64 is easy to be adsorbed on the surface of the U-shaped smooth sheet 4. Since the suction cup 64 is a flexible structure, the suction cup 64 is compressed at this time, so the gasket 641 on the suction cup 64 moves toward the patient, and the gasket 641 squeezes the supporting ring 651, so that the electrode patch 66 is closely attached to the patient's acupuncture point; repeat the above operation, and attach the electrode patch 66 corresponding to the other electrode sheet assembly 6 to another acupuncture point of the patient; then, current is introduced into the electrode patch 66 through the current generator 2, and a current loop is formed on the two acupuncture points of the patient. The current generator 2 emits a current of appropriate frequency to stimulate the patient's acupuncture points, so as to achieve a therapeutic effect.

[0036] In this embodiment, by adsorbing the suction cup 64 onto the U-shaped smooth thin sheet 4, direct contact between the suction cup 64 and the patient's skin is avoided, thereby preventing the sweat, oil, etc. on the patient's skin surface from affecting the adsorption effect of the suction cup 64; at the same time, it also avoids the patient's skin being directly sucked into the suction cup 64, thereby avoiding a bad experience for the patient; in addition, each electrode sheet assembly 6 has four suction cups 64 arranged in a circular array, and the surface roughness of the U-shaped smooth thin sheet 4 is relatively low, which effectively enhances the adsorption effect of the suction cup 64, thereby facilitating the electrode patch 66 to be stably attached to the patient's acupuncture points, and preventing the electrode patch 66 from falling off during treatment.

[0038] See also Figure 1-Figure 9 This embodiment is based on the first embodiment, and two support rods 67 are provided on the support block 61, and the two support rods 67 are fixedly connected to the support block 61; the two support rods 67 are arranged in parallel, and the two ends of the two support rods 67 penetrate the two flexible strips 62 respectively; specifically, the flexible strip 62 is penetrated with a through hole adapted to the support rod 67, and the through hole and the support rod 67 are in an interference fit manner, and the two ends of each support rod 67 penetrate two flexible strips 62 respectively; at the same time, the outer sleeve of each support rod 67 A first retaining ring 671 and a second retaining ring 672 are provided, and both the first retaining ring 671 and the second retaining ring 672 are fixedly connected to the support rod 67; the positions of the first retaining rings 671 on the two support rods 67 correspond, and the positions of the second retaining rings 672 on the two support rods 67 correspond, and the first retaining rings 671 and the second retaining rings 672 are located on both sides of the support block 61; the first retaining ring 671 and the second retaining ring 672 are in contact with the adjacent sides of the two flexible strips 62 respectively; the two flexible strips 62 are limited by the first retaining ring 671 and the second retaining ring 672 respectively.

[0039] Embodiment 3

[0040] See also Figure 1-Figure 9 This embodiment is based on the second embodiment, and the end threads of the two support rods 67 are matched with threaded covers 68. Specifically, the ends of the support rods 67 are provided with external threads matched with the threaded covers 68. The threaded covers 68 are used to press against the non-adjacent sides of the two flexible strips 62, that is, through the functions of the threaded covers 68, the first retaining ring 671 and the second retaining ring 672, the two sides of the two flexible strips 62 are limited; in addition, since the support rods 67 are passed through the flexible strips 62, the flexible strips 62 can be disassembled by unscrewing the threaded covers 68, thereby facilitating the removal of the support ring 651 from between the four suction cups 64, and further facilitating the cleaning or replacement of the support ring 651, the support ring 652 and the electrode patch 66.
