Abstract
Description
Technical Field
[0001] This utility model relates to the field of defibrillation electrodes, and in particular to a defibrillation electrode and medical device. Background Technology
[0002] In related technologies, the surface of the metal conductive layer of a defibrillator electrode is generally coated with a conductive gel, and then an anti-sticking film is applied to the surface of the conductive gel. The wires of the defibrillator electrode are generally placed between the conductive gel and the metal conductive layer. Therefore, during long-term storage, the conductive gel may corrode the wires, causing the defibrillator electrode to malfunction. Thus, how to prevent the conductive gel from corroding the wires during long-term storage has become an urgent problem to be solved. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a defibrillation electrode and medical device that can effectively prevent the conductive gel from corroding the wires during long-term storage.

[0009] The defibrillation electrode according to embodiments of this utility model has at least the following beneficial effects: By dividing the metal conductive film into upper and lower parts and setting an insulating film in the first part, the conductive gel can be effectively isolated from the upper wire, avoiding chemical corrosion of the wire by the gel during long-term storage. By setting the edge of the conductive gel to protrude from the metal conductive film, a uniform electric field distribution can be ensured when in contact with the skin, while avoiding skin irritation caused by the edge of the metal conductive film.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0024] Reference Figure 1 and Figure 2 This utility model embodiment provides a defibrillation electrode, which includes an insulating carrier film 100, a polymer film 200, a metal conductive film 300, and a polymer anti-adhesion film 400. The polymer film 200 is adhered to the top of the insulating carrier film 100, and the metal conductive film 300 is adhered to the top of the polymer film 200. The edge of the insulating carrier film 100 protrudes from the polymer film 200, and the edge of the polymer film 200 protrudes from the metal conductive film 300. The insulating carrier film 100, the polymer film 200, and the metal conductive film 300 are bonded together with adhesive.
[0025] It should be noted that the metal conductive film 300 includes a first part 301 and a second part 302. The first part 301 is located above the second part 302. The first part 301 is provided with an insulating film 310, and the second part 302 is provided with a conductive gel 320. By dividing the metal conductive film 300 into upper and lower parts and providing an insulating film 310 in the first part 301, the conductive gel 320 can be physically isolated from the wire 500 located in the first part 301, thus avoiding chemical corrosion of the wire 500 by the gel during long-term storage.
[0026] Specifically, the insulating film 310 has an adhesive area 311 on the side near the conductive gel 320. The adhesive area 311 is coated with adhesive so that it can adhere to the metal conductive film 300. The edge of the conductive gel 320 protrudes from the edge of the second part 302. By setting the edge of the conductive gel 320 to protrude from the metal conductive film 300, a uniform electric field distribution can be ensured when in contact with the skin, while avoiding skin irritation caused by the edge of the metal conductive film 300.
[0027] Understandably, the polymer anti-adhesive film 400 is adhered to the top of the conductive gel 320. The shape of the polymer anti-adhesive film 400 is the same as that of the insulating carrier film 100. That is, the polymer anti-adhesive film 400 covers both the insulating film 310 and the conductive gel 320, which can completely cover the conductive gel 320 to prevent oxidation and drying, and will not produce excess edges that would cause the anti-adhesive film to peel off. Since the conductive gel 320 is inherently adhesive, the polymer anti-adhesive film 400 does not need to be bonded with adhesive tape.
[0028] Specifically, both the polymer anti-stick film 400 and the polymer film 200 are made of PET material.
[0029] Understandably, the defibrillation electrode also includes a wire 500 and a metal fixing block 530. The wire 500 includes a plug end 520 and a connection end 510. The connection end 510 is a metal ring. The insulating carrier film 100 has a first through hole 101, the polymer film 200 has a second through hole 201, and the first part 301 has a third through hole 303. The metal fixing block 530 is sequentially inserted through the metal ring, the first through hole 101, the second through hole 201, and the third through hole 303. The insertion structure of the metal ring connection end 510 and the multi-layer through holes ensures that the connection point of the wire 500 completely avoids the conductive gel 320 area, eliminating the possibility of corrosion in physical space.
[0030] It should be noted that the defibrillation electrode also includes a metal pad 540, which is disposed between the metal conductive film 300 and the insulating film 310. The metal fixing block 530 is connected to the metal pad 540 after passing through the metal ring, the first through hole 101, the second through hole 201 and the third through hole 303 in sequence. The metal pad 540 acts as a stress dispersion layer, which evenly transmits the tension of the wire 500 to the entire metal conductive film 300, avoiding local stress concentration that could cause the conductive layer to break.
[0031] It should be noted that the defibrillation electrode also includes a first insulating block 600. The first insulating block 600 has an installation groove. The first insulating block 600 is attached to the bottom of the insulating carrier film 100. The metal fixing block 530 is located in the installation groove. The first insulating block 600 wraps around the metal fixing block 530 through the installation groove, eliminating the risk of short circuit caused by accidental contact with metal parts during operation.
[0032] It should be noted that the defibrillation electrode also includes a second insulating block 700, which has the same shape as the first insulating block 600. The second insulating block 700 is attached to the side of the first insulating block 600 away from the insulating carrier film 100.
[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
