Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an electrotherapy meridian stimulation enhancement component. Background Art

[0002] Electrical stimulation therapy uses a certain amount of electric current to stimulate transcortical acupuncture points, neurons, or muscles. By stimulating the meridians with electric pulses, it can quickly open up the meridians and promote blood circulation and remove blood stasis. When electrotherapy acts on the human body, it can dilate blood vessels, reduce blood flow resistance and blood viscosity, and thus improve microcirculation. Electrotherapy helps to improve neurological diseases and mental disorders, especially for the rehabilitation of patients with dementia. Transcranial electrical stimulation therapy is a targeted brain stimulation technology that introduces weak currents into the brain through electrodes and uses low-intensity trace currents to regulate the activity of neurons in the cerebral cortex. Depending on the polarity of the stimulation, it can cause hyperpolarization or depolarization changes in the resting membrane potential of neurons. It has the characteristics of being painless, non-invasive, safe to operate, reliable and convenient.

[0003] However, during the actual electrical stimulation treatment, the electrode cannot be fixed at the treatment position by itself, and needs to be fixed at the treatment position by auxiliary devices such as tape. The fixing effect is not good, and gaps are easily formed between the electrode and the skin, resulting in insufficient electrical contact between the two, affecting the effect of electrical stimulation treatment. Although the currently used negative pressure electrotherapy uses a suction cup to improve the fixing effect, the manufacturing volume of the vacuum component of the suction cup cannot be reduced, so it cannot be used in small acupuncture points in local areas such as the head and arms (such as the temple and Shenmen acupoint). At the same time, the electrotherapy suction cup needs to rely on the soft fit of subcutaneous tissue such as fat to form a stable adsorption force, so it cannot be used in scalp areas with less subcutaneous fat tissue. The above factors have led to the limitation of the effect of transcranial electrical stimulation. Therefore, a new technical solution is needed to improve it. Summary of the invention

[0004] In response to the above-mentioned problems in the prior art, the present invention provides an electrotherapy meridian stimulation enhancement component, which can fix the electrode position during transcranial electrical stimulation treatment and make the electrode fully contact with the skin, thereby improving the effect of electrical stimulation treatment.

[0005] The present invention is implemented by the following technical scheme: an electrotherapy meridian stimulation enhancement component, comprising a straight portion, the straight portion is a horizontally arranged straight plate-shaped body, both ends of the straight portion are connected to an operating portion, the operating portion is a vertically arranged plate body, the bottom end of each operating portion is connected to a working portion, the working portion is a horizontally arranged plate body, and the extension direction of the plate body of each working portion is away from the straight portion; An auxiliary part and a pre-tightening part are connected between the operating parts on both sides, the auxiliary part is located above the straight part, and the pre-tightening part is located below the straight part; the auxiliary part and the pre-tightening part are both arc-shaped elastic plates arranged laterally, the plate body of the auxiliary part is arc-shaped and convex upward, and the plate body of the pre-tightening part is arc-shaped and convex downward; The lower surface of the working part is provided with an adhesive layer; the horizontal height a of the lower surface of the working part and the horizontal height b of the lower surface of the pre-tightening part meet the following conditions: a≤b; The plate body of the pre-tightening part is penetrated by a mounting hole, and the inner diameter of the mounting hole is adapted to the size of the electrical stimulation terminal.

[0006] Furthermore, the mounting hole forms an interference fit with the electrical stimulation terminal.

[0007] Furthermore, the auxiliary portion and the straight portion are both provided with avoidance holes, and the avoidance holes are used to avoid the electrical stimulation terminal or the electrical lead.

[0008] Furthermore, the adhesive layer is made of biological glue or medical polyurethane glue.

[0009] Furthermore, the thickness x of the operating portion, the thickness y of the straight portion, the thickness of the auxiliary portion and the thickness z of the pre-tightening portion satisfy: x>y>z.

[0010] Beneficial effect: The present invention drives the deformation of the auxiliary part and the pre-tightening part by clamping the operating part with the straight part being equivalent to the rotating axis. When in use, the operating parts on both sides are clamped by fingers and brought close to each other, and the auxiliary part is deformed by the clamping force of the operating part, and the plate body of the auxiliary part bulges upward in an arc shape; the straight part serves as a fulcrum to remain stationary, and at the same time, the two ends of the straight part are equivalent to the rotating axis, so that the working part is driven by the operating part to extend in the direction away from the straight part, and the pre-tightening part is pulled to reduce the degree to which the arc shape of its plate body bulges downward, resulting in an upward deformation trend and being straightened. At this time, the adhesive layer on the lower surface is adhered to the patient's skin, and then the two operating parts are slowly released, so that the arc-shaped elastic plates of the auxiliary part and the pre-tightening part rebound to the original state before deformation at the same time, the auxiliary part rebounds downward, the pre-tightening part rebounds downward, and the electrical stimulation end fixed to the pre-tightening part moves downward; at the same time, the working parts on both sides drive the adhered skin to be subjected to the retraction and extrusion force, and the skin between the working parts on both sides forms wrinkles and bulges upward. At this time, the bulging skin can resist each other with the electrode at the pre-tightening part that rebounds downward, and form a full contact state with continuous pre-tightening force, effectively improving the electrical contact tightness between the skin and the electrode, and ensuring the effect of electrical stimulation treatment. This method can break through the technical limitations of traditional electrical contact gaps, electrotherapy suction cup defects, etc., and is particularly suitable for scalp areas with less subcutaneous fat tissue and local small acupuncture points, improving the effect of transcranial electrical stimulation treatment.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1 to 6 As shown, an electrotherapy meridian stimulation enhancement component includes a straight portion 1, which is a horizontally arranged straight plate-shaped body. An operating portion 2 is connected to each of the two ends of the straight portion 1. The operating portion 2 is a vertically arranged plate body. The bottom end of each operating portion 2 is connected to a working portion 3, which is a horizontally arranged plate body. The extension direction of the plate body of each working portion 3 is away from the straight portion 1. The above arrangement can realize that the operating portion 2 drives the working portion 3 to extend away from the straight portion 1 with the straight portion 1 as a fulcrum.

[0015] An auxiliary part 4 and a pre-tightening part 5 are connected between the operating parts 2 on both sides. The auxiliary part 4 is located above the straight part 1, and the pre-tightening part 5 is located below the straight part 1; the auxiliary part 4 and the pre-tightening part 5 are both laterally arranged arc-shaped elastic plates, the plate body of the auxiliary part 4 is arc-shaped and convex upward, and the plate body of the pre-tightening part 5 is arc-shaped and convex downward. The above arrangement can make the forces of the auxiliary part 4 and the pre-tightening part 5 compensate for each other and cooperate with each other. When the auxiliary part 4 is subjected to force, its ends are close to each other, and the convex part is convex upward. With the straight part 1 as the rotation axis, the ends of the pre-tightening part 5 are away from each other to support the working part 3, and the force has a tendency to straighten, and the degree of convexity is reduced.

[0016] An adhesive layer 6 is provided on the lower surface of the working part 3; the horizontal height a of the lower surface of the working part 3 and the horizontal height b of the lower surface of the pre-tightening part 5 meet the following conditions: a≤b, thereby ensuring that the pre-tightening part 5 is in full contact with the skin after rebounding and avoiding compression trauma when the electrode contacts the patient's skin.

[0017] The plate body of the pre-tightening part 5 is penetrated by a mounting hole 7, the inner diameter of which is matched with the size of the electric stimulation terminal 9, so as to avoid the electric stimulation terminal 9 from loosening during electrotherapy and to avoid affecting the effect of the electric stimulation treatment.

[0018] This embodiment clamps the operating part 2 and uses the straight part 1 as the rotating axis to drive the deformation of the auxiliary part 4 and the pre-tightening part 5, so that the working part 3 acts on the skin to form wrinkles. It can fix the electrode position during transcranial electrical stimulation treatment and make the electrode fully contact with the skin, thereby improving the effect of electrical stimulation treatment.

[0019] In this embodiment, the mounting hole 7 forms an interference fit with the electric stimulation terminal 9. The above arrangement enables the electric stimulation terminal 9 to move along with the shape change of the pre-tightening portion 5, and to keep in close contact with the patient's skin during treatment, thereby preventing the electric stimulation terminal 9 from loosening during electrotherapy and affecting the effect of the electric stimulation treatment.

[0020] In this embodiment, the auxiliary portion 4 and the straight portion 1 are both provided with avoidance holes 8, which are used to avoid the electrical lead 10 (the two are preferably clearance-fitted), so as to avoid the electrical stimulation terminal 9 during installation and prevent other parts from obstructing or pulling the electrical lead 10 during use.

[0021] In this embodiment, the adhesive layer 6 is made of biological glue or medical polyurethane glue, which ensures that the adhesive layer 6 is firmly adhered and does not hurt or irritate the skin when torn, avoids allergies, and can be reused.

[0022] In this embodiment, the thickness x of the operating part 2, the thickness y of the straight part 1, the thickness z of the auxiliary part 4 and the thickness z of the pre-tightening part 5 satisfy: x>y>z. The above settings are designed according to the force of each part, so that the operating part 2 tends to the active driving function and the auxiliary part 4 tends to the passive deformation function, thereby ensuring the smooth implementation of the working process of the present invention.

[0023] The working principle of this embodiment is as follows: S1: Figure 5As shown, the operator can clamp the two operating parts 2 with one hand, and complete the clamping action by pinching the operating part 2 with the thumb and index finger, so that the operating parts 2 are close to each other, and the auxiliary part 4 is deformed by the clamping force of the operating part 2, and the plate body of the auxiliary part 4 bulges upward in an arc shape; the straight part 1 remains stationary as a fulcrum, and at the same time, the two ends of the straight part 1 are equivalent to the rotating shaft, so that the plate body of the operating part 2 rotates, so that the forces of the pre-tightening part 5 and the auxiliary part 4 compensate each other and cooperate with each other; when the auxiliary part 4 is subjected to force, its bulge bulges upward and forms an elastic The operating part 2 rotates to drive the working part 3 to extend away from the straight part 1, so that the ends of the pre-tightening part 5 are pulled away from each other and the working part 3 is stretched open. The pre-tightening part 5 is pulled by the operating parts 2 at both ends and the working part 3 and shows a tendency to straighten. The arc-shaped downward protrusion of the plate body of the pre-tightening part 5 is reduced to cause deformation and is straightened, and forms a tendency to rebound upward. At this time, the distance between the working parts 3 on both sides is in an expanded state, so that the adhesive layer 6 on the lower surface of the working part 3 can stick to the patient's skin.

[0024] S2: Figure 6 to Figure 7 As shown, the operator slowly releases the two operating parts 2, and the arc-shaped elastic plates of the auxiliary part 4 and the pre-tightening part 5 are simultaneously forced to rebound to their original states before deformation. At this time, the auxiliary part 4 releases the elastic force and rebounds downward to open the operating part 2, and again uses the two ends of the straight part 1 as the rotating axis to rotate the operating part 2 and squeeze the pre-tightening part 5, so that the pre-tightening part 5 rebounds downward, and the electric stimulation terminal 9 fixed on the pre-tightening part 5 moves downward; at the same time, the rebound of the working parts 3 on both sides can drive the adhered skin to be subjected to the retraction and squeezing force, so that the skin in the middle of the working parts 3 on both sides forms wrinkles and bulges upward. At this time, the bulging skin can resist each other with the electric stimulation terminal 9 at the pre-tightening part 5 that rebounds downward, and form a full contact state with continuous pre-tightening force, effectively improving the electrical contact tightness between the skin and the electrode, and ensuring the electric stimulation treatment effect.

[0025] Through the above-mentioned operation method, the technical limitations such as traditional electrical contact gaps and electrotherapy suction cup defects can be effectively broken through. The contact area does not need to rely on soft fat tissue to achieve sufficient electrical contact effect. It is especially suitable for scalp areas with less subcutaneous fat tissue and local small acupuncture points, thereby improving the therapeutic effect of transcranial electrical stimulation.

[0026] The present invention has been specifically described above in conjunction with the embodiments. Various improvements can still be made without departing from the core scope of the present invention, and equivalents can be used to replace the components therein. As long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be used in combination with each other in any way. These combinations are not exhaustively described in this specification, which is only for the purpose of saving space and resources.
