Description

Technical Field

[0001] This utility model relates to the field of wearable electrocardiogram (ECG) electrode pads, specifically a set of ECG electrode pads for teaching. Background Technology

[0002] ECG electrode pads are consumables used in conjunction with cardiac monitoring equipment or electrocardiographs to collect cardiac signals. In medical practice, commonly used disposable ECG electrode pads include... Figure 1 As shown, it includes a conductive electrode 11, a metal clip 12 fixed to the conductive electrode 11, a positioning backing 13 for fixing the conductive electrode 11 and the metal clip 12, an adhesive layer 14 located at the bottom of the positioning backing 13, and a release film 15 covering the adhesive layer 14. The positioning backing 13 is generally made of foam or non-woven fabric. The conductive electrode 11 is also coated with conductive adhesive 16 on the side that contacts the human body. In use, the release film is peeled off to expose the adhesive layer 14 and the conductive adhesive 16. The electrode is then attached to the surface of the human skin using the adhesive layer 14, and the electrocardiogram measuring device is temporarily fixed to the metal clip 12 via a connector. The conductive adhesive 16 can also be applied to the outer surface of the conductive electrode 11 before use.

[0003] When teaching the use of ECG electrode pads in nursing colleges, teachers demonstrate the method and then have students practice on their own. The amount of ECG electrode pads used is very large, and in most cases, long-term monitoring is not required, resulting in the ECG electrode pads not being fully utilized and causing waste.

[0004] Regarding how to fully utilize ECG electrode pads, Chinese patent document CN214860589U discloses a replaceable electrode patch for cardiology, including an electrode pad body. A connecting rod is fixed to the top surface of the electrode pad body, and a conductive head is fixedly connected to the top surface of the connecting rod. From bottom to top, the outer surface of the connecting rod is movably fitted with an adhesive layer, a non-woven fabric layer, and an electrocarbon layer. The top surfaces of the adhesive layer, non-woven fabric layer, and electrocarbon layer are respectively provided with a first, second, and third slot. Through the first, second, and third slots, the adhesive layer, non-woven fabric layer, and electrocarbon layer can be movably engaged with the connecting rod from the side, allowing for convenient removal and installation. This facilitates the replacement of clean and undamaged adhesive, non-woven fabric, and electrocarbon layers, enabling the recycling of the electrode pad body and providing a new approach to improving electrode pad reusability. However, after replacing these components, the electrode patch is prone to becoming scattered, making it unsuitable for teaching students who are new to electrode pads. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a set of ECG electrode pads for teaching, so that the ECG electrode pads can be used multiple times without changing the main structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] The teaching ECG electrode pad kit includes an electrode pad body, which has a conductive electrode, a metal buckle, a positioning backing, an adhesive layer, a release film, and conductive adhesive. It also includes several adhesive pads, which are adhesive on both sides and covered with a release film. The adhesive pads have a through hole in the middle, the position of which corresponds to the position of the conductive electrode on the positioning backing. The release film covers the through hole, and the through hole contains conductive adhesive.

[0008] The inventive concept of this invention lies in adding an adhesive sheet to increase the number of times the electrode pad can be used, for reattaching the electrode pad to the human body. Since the adhesiveness of the electrode pad weakens after being removed from the body, the adhesive sheet has adhesive on both sides: one side is used to fix the electrode pad to the adhesive layer, and the other side is used to fix it to the human skin. Because the conductive adhesive on the electrode pad has been in direct contact with the previous person, a layer of conductive adhesive is still provided at the through-holes of the adhesive sheet to cover the original conductive adhesive, making it relatively safe and hygienic when in contact with a second student's skin. For the third use, the previous adhesive sheet can be peeled off and the conductive adhesive wiped away, or another layer of adhesive sheet can be directly applied.

[0009] As an improvement, one side of the adhesive sheet shares a release film with the electrode sheet body, on which one electrode sheet body and 5-10 adhesive sheets are pre-fixed. This solution provides a preferred option. Due to students' unfamiliarity with the operation, the positioning backing may develop relatively obvious wrinkles or deformations after the electrode sheet body is used about 10 times, making it unsuitable for reuse. Obviously, if the positioning backing is peeled off and pasted very carefully, the number of times the electrode sheet body can be used is not limited.

[0010] As a further improvement, a handle is provided on one side of the adhesive sheet, and the handle is non-adhesive. The handle facilitates the peeling of the adhesive sheet from the release film or electrode sheet body.

[0011] As an improvement, the positioning backing is made of foam or non-woven fabric.

[0012] As an alternative, the teaching ECG electrode pad kit may also include an electrode pad body, several adhesive pads, and bottled conductive adhesive. The electrode pad body has a conductive electrode, a metal clip, a positioning backing, an adhesive layer, and a release film. The adhesive pads are sticky on both sides and covered with release film on both surfaces. A through hole is formed in the center of the adhesive pad, the position of which corresponds to the position of the conductive electrode on the positioning backing, and the release film covers the through hole. The conductive adhesive is applied directly from the bottled conductive adhesive before use.

[0013] As a further improvement, the adhesive sheets are stacked on top of each other when not in use, making them convenient to store and carry.

[0014] In summary, this utility model has the advantages of simple structure and easy operation, allowing the electrode sheet to be used multiple times, thus saving teaching costs while ensuring teaching effectiveness. Attached Figure Description

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] Example 1

[0023] like Figure 2 As shown, the teaching ECG electrode pad kit described in this scheme includes a square release film 15, an electrode pad body 10 located on the release film 15, and eight adhesive pads 20. The electrode pad body 10 uses disposable ECG electrode pads commonly used in the prior art, and its structure is as follows... Figure 1As shown, the electrode body 10 includes a conductive electrode 11, a metal buckle 12, a positioning backing 13, an adhesive layer 14, and a release film 15. The positioning backing 13 is made of foam or non-woven fabric, and the conductive electrode 11 has conductive adhesive 16 pre-coated on the side closest to the skin. Unlike existing technologies, the release film 15 of the electrode body 10 has an increased area and is square, allowing it to fix eight adhesive sheets 20. The shape of the adhesive sheets 20 corresponds to the shape of the electrode body 10. In this application, the adhesive sheets 20 are circular, made of 0.5mm thick plastic, and are adhesive on both sides. The other side of the adhesive sheet 20 is covered with a circular release film 15, the area of ​​which corresponds to the outer circumference of the adhesive sheet 20.

[0024] like Figure 3 As shown, a handle 22 is provided on one side of the adhesive sheet 20, and the handle 22 is non-adhesive. A through hole 21 is formed in the middle of the adhesive sheet 20, and the position of the through hole 21 corresponds to the position of the conductive electrode 11 on the positioning backing 13, so that when the adhesive sheet 20 is attached to the bottom surface of the electrode sheet body 10, the through hole 21 faces the conductive electrode 11 of the electrode sheet body 10. A circular release film 15 covers the other side of the adhesive sheet 20, and the area of ​​the circular release film 15 corresponds to the area of ​​the adhesive sheet 20. In this application, the outer edge of the circular release film 15 extends about 1 mm beyond the outer edge of the adhesive sheet 20. The circular release film 15 covers the through hole 21, and the through hole 21 contains conductive adhesive 16.

[0025] After peeling the electrode body 10 off the first student's skin, use your fingers to hold the handle 22 and remove the adhesive patch 20 from the square release film 15. Place the adhesive patch 20 over the adhesive layer 14 of the electrode body 10, with the through-hole 21 of the adhesive patch 20 facing the conductive electrode 11. While removing the adhesive patch 20 from the square release film 15, ensure that the conductive adhesive 16 at the through-hole 21 is removed along with the adhesive patch 20 and covers the conductive adhesive 16 of the electrode body 10. Finally, peel off the circular release film 15 on the other side of the adhesive patch 20 and then fix the electrode body 10 to the second student's skin. When removing the electrode body 10 from the second student's skin, you can either directly attach another adhesive patch 20, or peel off the existing adhesive patch 20 first and then attach it.

[0026] Example 2

[0027] like Figure 4 As shown, the ECG electrode kit for teaching described in this embodiment includes a square release film 15, one electrode body 10 and eight adhesive sheets 20 located on the release film 15, and a bottle of conductive adhesive 16. The conductive adhesive 16 is not pre-installed on the electrode body 10 and the adhesive sheets 20; it is added before use.

[0028] Obviously, in addition to the traditional circular shape, the electrode body 10 can also take other shapes, such as square or oblong. In this case, the shape of the adhesive sheet 20 can be adaptively adjusted to fit the shape of the electrode body 10.

[0029] Example 3

[0030] In this embodiment, the electrode pad body 10 adopts a disposable ECG electrode pad from the prior art. The adhesive sheets 20 are stacked on top of each other when not in use, as shown in the image. Figure 5 As shown, a circular release film 15 is provided between adjacent adhesive sheets 20, and the handles 22 of adjacent adhesive sheets 20 are staggered at a certain angle for easy handling. The conductive adhesive 16 can be pre-applied to the through holes 21 of the adhesive sheets 20, or it can be added by dripping bottled conductive adhesive 16 before use.
