Description

Technical Field

[0001] The present invention mainly relates to electric field coupling negative pressure therapy technology, and in particular to an outer edge electrode for an electric field therapy device. Background Art

[0002] Acute skin and soft tissue injuries are the main types of trauma. Due to the complexity of the injury, untimely treatment and negligent nursing, skin wound infection and blood supply disorders are prone to occur, resulting in prolonged wound healing. At the same time, with the aging of my country's population, the incidence of skin ulcers caused by various chronic diseases such as diabetes, vascular diseases, and pressure sores has increased year by year. Due to poor blood circulation in the wound, proliferation and migration disorders of skin repair cells at the wound edge, chronic wounds are often formed, making the wound difficult to heal, seriously affecting the patient's appearance and functional recovery.

[0003] Continuous or intermittent wound closure negative pressure drainage of a certain intensity can avoid wound infection through continuous drainage, effectively promote wound endothelial cell proliferation, angiogenesis and granulation tissue formation, etc., and play an important role in maintaining a good wound microenvironment and promoting wound healing. At present, wound closure negative pressure drainage technology has been well applied in the treatment of various acute and chronic wounds. The endogenous electric field of the wound refers to the direct current electric field spontaneously formed during the wound healing process with the normal skin at the wound edge as the positive pole and the center of the wound as the negative pole. This direct current electric field can promote the proliferation of wound repair-related cells and migration to the center of the wound, and promote the growth of wound edge nerves to the wound, thereby playing an important role in wound epithelialization and wound healing. Therefore, based on the principle that the endogenous electric field of the wound promotes wound healing, applying an exogenous electric field of a certain intensity to the wound, and making the positive pole of the exogenous electric field located at the wound edge and the negative pole located at the center of the wound (simulating the endogenous electric field), will accelerate the healing of acute and chronic wounds.

[0004] During the operation of applying the electric field, due to the special conditions of the wound surface, the shape of the wound edge is irregular, the size is uncertain, and the laying surface is distorted and changeable. Conventional strip electrodes or ring electrodes cannot match the outer edge configuration, which often leads to warping of the electrode and the skin, false contact, and problems such as excessive gaps or no laying positions. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an outer edge electrode for an electric field therapy device which can realize customization of laying path, laying curve surface and laying length.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An outer edge electrode for an electric field treatment device comprises a power supply wire and an electrode strip, wherein the power supply wire and the electrode strip are electrically connected, and the side edges of the electrode strip are provided with deformation avoidance openings at intervals to facilitate the electrode strip to deform so as to match the outer edge configuration.

[0008] As a further improvement of the above technical solution:

[0009] The area of ​​the electrode strip region corresponding to the deformation avoidance opening is smaller than the area of ​​the electrode strip region not corresponding to the deformation avoidance opening.

[0010] The deformation avoidance opening is arranged on one side of the electrode strip.

[0011] The deformation avoidance openings are arranged on both sides of the electrode strip.

[0012] The electrode strips are provided with deformation avoidance openings on both sides of the same position in the length direction.

[0013] The deformation avoidance openings on both sides are offset from each other in the length direction of the electrode strip.

[0014] The radial direction of the deformation avoidance opening gradually increases toward the outside of the electrode strip.

[0015] The deformation avoidance opening is configured as a triangular opening.

[0016] The deformation avoidance opening is configured as a trapezoidal opening.

[0017] The deformation avoidance opening is configured as an arc-shaped opening.

[0018] The electrode strip comprises a power-carrying layer and a conductive layer which are connected to each other, the power-carrying layer is electrically connected to a power supply wire, and the deformation avoidance opening is provided on the power-carrying layer and the conductive layer.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] The outer edge electrode of the electric field treatment device of the present invention is used. When the wound surface is used, necessary pretreatment is first performed on the wound surface, and then the electrode strip is laid on the skin section by section following the outer edge of the wound surface (at this time, the deformation avoidance opening produces deformation avoidance) until the entire wound surface is surrounded, and the excess part can be cut off. Compared with the traditional structure, the electrode strip is divided into "contact gain zone (the area of ​​the electrode strip main body on both sides of the deformation avoidance port is larger)" and "deformation adaptation zone (the area of ​​the electrode strip main body corresponding to the deformation avoidance port is smaller)" by the deformation avoidance port. The two zones are arranged alternately, among which the "contact gain zone" has a larger contact area with the skin. Since it is divided by the "deformation adaptation zone", the contact with the skin in the zone is more similar to a plane, ensuring the conductive performance of the contact, while the "deformation adaptation zone" has less or no contact with the skin. The zone is provided with a deformation avoidance port suitable for generating a swing angle in the plane, and also with a "deformation adaptation zone" suitable for space distortion. The "bead chain" electrode thus formed has the characteristics of customized laying path, customized laying surface and customized laying length. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1:

[0032] Figures 1 to 3The first embodiment of the outer edge electrode of the electric field treatment device of the present invention is shown, comprising a power supply wire 1 and an electrode strip 2, the power supply wire 1 and the electrode strip 2 are electrically connected, and the side edge of the electrode strip 2 is provided with a deformation avoidance opening 21 at intervals to facilitate the electrode strip 2 to deform to match the outer edge configuration of the laying. When in use, the wound surface is first pre-treated as necessary, and then the electrode strip 2 is laid on the skin section by section following the outer edge of the wound surface (at this time, the deformation avoidance opening 21 generates deformation avoidance) until the entire wound surface is surrounded, and the excess part is cut off. Compared with the traditional structure, the electrode strip 2 is divided into a "contact gain zone (the area of ​​the electrode strip 2 with a larger main body area on both sides of the deformation avoidance opening 21)" and a "deformation adaptation zone (the area of ​​the electrode strip 2 with a smaller main body area corresponding to the deformation avoidance opening 21)" by the deformation avoidance opening 21. The two areas are alternately arranged, and the "contact gain zone" has a larger contact area with the skin. Since it is divided by the "deformation adaptation zone", the contact with the skin in the zone is more similar to a plane, ensuring the conductive performance of the contact, while the "deformation adaptation zone" has less or no contact with the skin. The zone is provided with a deformation avoidance opening 21 suitable for generating a swing angle in the plane, and is also provided with a "deformation adaptation zone" suitable for space distortion. The "bead chain" electrode thus formed has the characteristics of customized laying path, customized laying surface and customized laying length.

[0033] In this embodiment, the area of ​​the electrode strip 2 corresponding to the deformation avoidance opening 21 is smaller than the area of ​​the electrode strip 2 not corresponding to the deformation avoidance opening 21. The structure is simple and reliable.

[0034] In this embodiment, the electrode strip 2 includes a power-carrying layer 22 and a conductive layer 23 that are connected to each other. The power-carrying layer 22 is electrically connected to the power supply wire 1, and the deformation avoidance opening 21 is provided on the power-carrying layer 22 and the conductive layer 23. The power-carrying layer 22 is connected to the power supply wire 1, and is also in contact with the conductive layer 23 for electrical conduction. At the same time, since the mechanical tensile and shear strength of the power-carrying layer 22 is weak, the power-carrying layer 22 also compensates for the mechanical stability of the entire electrode. The power-carrying layer 22 and the conductive layer 23 are mechanically and electrically connected, and the conductive layer 23 is in contact with the skin for electrical conduction. The entire electrode can be in contact with the skin in at least two ways: the conductive layer 23 is directly bonded to the skin, or other adhesive is added to the outside of the electrode to press the electrode against the skin.

[0035] In this embodiment, the deformation avoidance openings 21 are provided on both sides of the electrode strip 2. In this structure, the deformation avoidance openings 21 are located on both sides of the electrode strip 2, which can realize the customization of the laying path, laying curve surface and laying length of the electrode strip 2, and the deformation avoidance openings 21 on both sides further improve the deformation capability.

[0036] In this embodiment, the electrode strip 2 is provided with deformation avoidance openings 21 on both sides of the same position in the length direction, that is, the positions of the deformation avoidance openings 21 on both sides correspond to each other, and the structure is simple and easy to implement.

[0037] In this embodiment, the diameter of the deformation avoidance opening 21 gradually increases toward the outside of the electrode strip 2. This arrangement ensures the reliability and smoothness of the deformation.

[0038] In this embodiment, the deformation avoidance opening 21 is configured as a triangular opening, and its structure is simple and easy to implement.

In this structure, the deformation avoidance opening 21 is located on one side of the electrode strip 2, which can realize the customization of the laying path, laying surface and laying length of the electrode strip 2.

That is, the positions of the deformation avoidance openings 21 on both sides are mutually offset, and the structure is simple and easy to implement.

Its structure is simple and easy to implement.

Its structure is simple and easy to implement.
