Description

Technical Field

[0001] This utility model belongs to the field of medical electrode pad technology, and specifically relates to an improved electrode pad. Background Technology

[0002] Electrode pads are conductive components used in medical monitoring equipment or industrial batteries. In clinical medicine, disposable electrode pads are widely used in electrocardiogram monitoring, electrotherapy and other scenarios. Their traditional structure usually includes a non-woven fabric base, a conductive paste layer, an electrode clip and a silver chloride connecting wire. The non-woven fabric base serves as a carrier to fix the electrode pad to the patient's skin surface.

[0003] Traditional disposable electrode pads have obvious drawbacks:

[0004] Some patients experience allergic reactions to non-woven fabrics, which can easily cause skin damage at the application site. Mild cases may present with local redness, swelling, heat, pain, itching, and slight erythema, while severe cases can lead to blisters, oozing, or even skin ulceration. This not only seriously affects the patient's skin comfort but may also interfere with the normal conduct of medical monitoring or treatment. At the same time, traditional electrode pads only have conductive and fixation functions and cannot treat existing skin allergies or damage. Medical staff need to take additional skin care measures, which increases the workload of medical staff and prolongs the patient's recovery period.

[0005] Therefore, we propose an improved electrode sheet. Utility Model Content

[0006] The purpose of this invention is to provide an improved electrode pad to address the issues raised in the background art, such as allergic reactions to non-woven fabric materials in some patients, leading to skin damage at the application site after use. Mild cases manifest as local redness, swelling, heat, pain, itching, and slight erythema, while severe cases can cause blisters, oozing, or even skin ulceration. This not only seriously affects the patient's skin comfort but may also interfere with the normal conduct of medical monitoring or treatment. Furthermore, traditional electrode pads only have conductive and fixation functions and cannot treat existing skin allergies or damage, requiring additional skin care measures from medical staff, increasing their workload and prolonging the patient's recovery period.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an improved electrode sheet, comprising an electrode sheet body, wherein the electrode sheet body includes an electrode assembly and a hydrocolloid transparent adhesive used in conjunction with the electrode assembly;

[0008] The electrode assembly includes an electrode buckle, a conductive layer, and a silver chloride connecting wire. The conductive layer is attached to one side of the electrode buckle, and the silver chloride connecting wire is electrically connected to the side of the electrode buckle away from the conductive layer. The electrode sheet body does not contain a non-woven fabric substrate.

[0009] The hydrocolloid transparent sticker has a mounting hole in the center, and the electrode clip passes through the inner wall of the mounting hole;

[0010] The conductive layer is attached to one side of the hydrocolloid transparent sticker.

[0011] By using the above solution, a hydrocolloid transparent patch is used instead of a non-woven fabric base, eliminating the sensitizing non-woven fabric substrate. Combined with the highly absorbent hydrocolloid transparent patch, skin damage caused by non-woven fabric is effectively avoided. Furthermore, the hydrocolloid transparent patch creates a sealed, moist environment and low oxygen tension on the skin surface. This isolates external bacteria and prevents skin infection; it also promotes local blood circulation, stimulates macrophages and interleukin release, relieves tissue edema, improves microcirculation, and protects nerve endings. It has a therapeutic effect on existing skin redness, itching, erythema, and even ulceration, achieving an integrated effect of electrode use and skin care. By setting the area of ​​the hydrocolloid transparent patch to be larger than the area of ​​the conductive layer, the stability of the electrode body during use is ensured, guaranteeing comprehensive protection around the application site.

[0012] In the above solution, it should be noted that the hydrocolloid transparent dressing is a type of hydrocolloid dressing. Its main components are highly hydrophilic carboxymethyl cellulose and synthetic rubber. It has a strong ability to absorb liquids and is breathable but not water-permeable. When the transparent dressing is applied to the sensitive skin, it can create a closed, moist environment and low oxygen tension locally, effectively isolating bacteria, promoting local blood circulation, stimulating macrophages and the release of interleukins, relieving local tissue edema, improving microcirculation, and protecting nerve endings.

[0013] In a preferred embodiment, the hydrocolloid transparent sticker is specifically made of highly hydrophilic carboxymethyl cellulose and synthetic rubber.

[0014] Using the above method, carboxymethyl cellulose has excellent water absorption properties, which can absorb skin exudates such as sweat and tissue fluid, thereby effectively maintaining the skin's moist environment. At the same time, the synthetic rubber provides appropriate adhesion to ensure that the electrode pad body has a good fixation effect, while also having good biocompatibility to avoid skin irritation. Furthermore, the overall transparency allows medical staff to observe the skin condition without removing the electrode pad body, making it convenient for operation and use.

[0015] In a preferred embodiment, the conductive layer is specifically a conductive paste, and the thickness of the conductive paste is 0.5mm-1mm.

[0016] By adopting the above solution, the thickness of the conductive paste is limited, which can ensure that the transparent hydrocolloid layer has sufficient adhesion and structural strength to avoid structural instability failure due to excessive thinness, and also avoid the overall structure being too thick, which would cause a foreign body sensation when wearing and applying it.

[0017] In a preferred embodiment, the portion of the electrode buckle that contacts the inner wall of the mounting hole is fixed by an interference fit.

[0018] The above solution utilizes the interference fit of the electrode clips to install them on the inner wall of the mounting hole, which facilitates installation and ensures good installation stability after installation, preventing accidental loosening and detachment.

[0019] In a preferred embodiment, the area of ​​the conductive layer is smaller than the area of ​​the hydrocolloid transparent sticker.

[0020] The above solution is designed to ensure that the hydrocolloid transparent sticker can completely cover the skin area around the conductive layer, thereby ensuring a sufficiently moist environment and effective protection at the adhesion site.

[0021] In a preferred embodiment, the bottom end of the electrode buckle passes through the mounting hole and is attached to the conductive layer.

[0022] By adopting the above scheme, it can be ensured that the electrode buckle can be effectively electrically connected to the conductive layer.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This improved electrode pad replaces the non-woven fabric base with a hydrocolloid transparent patch, eliminating the sensitizing non-woven fabric substrate. Combined with the highly absorbent hydrocolloid transparent patch, it effectively avoids skin damage caused by non-woven fabric. Furthermore, the hydrocolloid transparent patch creates a sealed, moist environment and low oxygen tension on the skin surface. This isolates external bacteria, preventing skin infection, while simultaneously promoting local blood circulation, stimulating macrophages and interleukin release, relieving tissue edema, improving microcirculation, and protecting nerve endings. It also has a therapeutic effect on existing skin redness, itching, erythema, and even ulceration, achieving an integrated effect of electrode use and skin care.

[0025] This improved electrode sheet ensures the stability of the electrode sheet body during use and provides all-around protection to the application site by setting the area of ​​the hydrocolloid transparent adhesive to be larger than the area of ​​the conductive layer.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-3 This utility model provides an improved electrode sheet, including an electrode sheet body;

[0032] The electrode pad body includes an electrode assembly 1 and a hydrocolloid transparent patch 2 used in conjunction with the electrode assembly 1. The hydrocolloid transparent patch 2 is made of highly hydrophilic carboxymethyl cellulose and synthetic rubber. Carboxymethyl cellulose has good water absorption properties and can absorb skin exudates, such as sweat and tissue fluid, thereby effectively maintaining the skin's moist environment. At the same time, synthetic rubber provides appropriate adhesion to ensure that the electrode pad body has a good fixation effect, while also having good biocompatibility to avoid skin irritation. Furthermore, the overall transparency allows medical personnel to observe the skin condition without removing the electrode pad body, making it convenient for operation and use.

[0033] The electrode assembly 1 includes an electrode buckle 3, a conductive layer 5, and a silver chloride connecting wire 4. The bottom end of the electrode buckle 3 passes through the mounting hole 6 and is attached to the conductive layer 5 to ensure that the electrode buckle 3 can be effectively electrically connected to the conductive layer 5.

[0034] The conductive layer 5 is attached to one side of the electrode buckle 3. The silver chloride connecting wire 4 is electrically connected to the side of the electrode buckle 3 away from the conductive layer 5. The electrode sheet body does not contain a non-woven fabric base. The conductive layer 5 is specifically a conductive paste, and the thickness of the conductive paste is 0.5mm-1mm. The thickness of the conductive paste is limited to ensure that the hydrocolloid transparent layer has sufficient adhesion and structural strength, avoiding structural instability failure due to excessive thinness, and also to avoid the overall structure being too thick, which would cause a foreign body sensation when wearing and pasting.

[0035] The hydrocolloid transparent patch 2 has a mounting hole 6 in the center. The electrode clip 3 passes through the inner wall of the mounting hole. The part of the electrode clip 3 that contacts the inner wall of the mounting hole 6 is fixed by an interference fit. The interference fit of the electrode clip 3 on the inner wall of the mounting hole 6 facilitates installation and ensures good installation stability after installation, preventing accidental loosening and falling off. The conductive layer 5 is attached to one side of the hydrocolloid transparent patch 2. The area of ​​the conductive layer 5 is smaller than the area of ​​the hydrocolloid transparent patch 2. This setting is to ensure that the hydrocolloid transparent patch 2 can completely cover the skin area around the conductive layer 5, thereby ensuring a sufficient range of moisture environment and effective protection at the adhesion position.

[0036] When using

[0037] Assembly: Cut off the electrode clip 3 and conductive paste in the middle of the electrode pad body. Cut an installation hole 6 in the middle of the hydrocolloid transparent sticker 2 with the same size as the outer periphery of the electrode clip 3. After tearing off the adhesive tape of the hydrocolloid transparent sticker 2, pass the electrode clip 3 through the middle of the hydrocolloid and stick it on the hydrocolloid transparent sticker 2. After cleaning the patient's skin, connect the modified electrode pad to the lead wire and stick it on the patient's skin.

[0038] The overall electrical connection monitoring is achieved using conductive paste, electrode clips 3, and silver chloride connecting wires 4;

[0039] Utilizing the excellent water absorption of the hydrocolloid transparent patch 2, a sealed, moist environment and low oxygen tension can be formed on the skin surface. On the one hand, it can isolate external bacteria and prevent skin infection; on the other hand, it can promote local blood circulation, stimulate macrophages and interleukin release, relieve tissue edema, improve microcirculation and protect nerve endings. It has a therapeutic effect on existing skin redness, itching, erythema and even ulceration, achieving the integrated effect of electrode use and skin care.
