[0002] In the medical field, electrode pads are widely used as key components of electrotherapy devices. However, traditional electrode pads have several problems. Regarding allergic reactions, many patients are allergic to the backing material of traditional electrode pads, experiencing localized skin redness, itching, rashes, blisters, and in severe cases, skin damage and oozing, significantly reducing the patient's experience and affecting the treatment process. In terms of fit and comfort, traditional electrode pads are difficult to fit tightly against the skin, affecting treatment effectiveness and causing discomfort with prolonged use. Furthermore, traditional electrode pads have poor conductivity and stability, resulting in uneven impedance and unstable electrical stimulation, making it difficult to guarantee the treatment effect.

[0003] In other words, how to provide a hydrocolloid electrode pad that solves the problems of skin allergies, poor fit and comfort, and poor conductivity and stability caused by traditional electrode pads, so as to provide patients with a better treatment experience and improve treatment results, is a technical problem that urgently needs to be solved in this field.

[0039] Specifically, this utility model provides a hydrocolloid electrode pad, including a hydrocolloid dressing 1, an electrode pad 2, a connecting layer 3, a conductive paste 4, and an electrode clip 5. The hydrocolloid dressing 1 has a mounting hole 11 in the middle. An electrode clip 5 for connecting to an external electrocardiogram monitoring device is fixed on one side of the electrode pad 2. The electrode pad 2 is arranged in the mounting hole 11. The connecting layer 3 is fixed between the outer edge of the electrode pad 2 and the side wall of the mounting hole 11. An adhesive layer is provided on one side of the hydrocolloid dressing 1. The conductive paste 4 covers the other side of the electrode pad 2 and the corresponding side of the connecting layer 3. The conductive paste 4 and the adhesive layer are located on the same side. This application uses a connecting layer 3 to fix the electrode pad 2 within the mounting hole 11 of the hydrocolloid dressing 1. The electrode pad 2 is then adhered to the skin via the adhesive layer of the hydrocolloid dressing 1. The hydrocolloid dressing 1 is made of a material with high waterproof performance, excellent moisture permeability, skin-friendliness, and low allergenicity, reducing the risk of skin allergies while ensuring good adhesion. The adhesive layer has moderate tack, ensuring the electrode pad 2 adheres firmly to the skin without causing damage during removal. The conductive paste layer ensures stable transmission of the electrical stimulation signal, preventing stinging pain caused by uneven impedance. Therefore, the hydrocolloid electrode pad provided in this application solves the problems of skin allergies, poor fit and comfort, and inadequate conductivity and stability associated with traditional electrode pads, providing patients with a better treatment experience and improving treatment outcomes.

[0040] In this application, the outer edge of the anti-curling layer 6 is circular, while the inner edge of the anti-curling layer 6 is adapted to the shape of the outer edge of the hydrocolloid dressing 1, such as... Figure 1 As shown, the anti-rolling layer 6 is annular, and the hydrocolloid dressing 1 is also circular.

[0041] In one possible implementation, the hydrocolloid electrode sheet further includes: an anti-curling layer 6, which is arranged around the periphery of the hydrocolloid dressing 1. The thickness of the anti-curling layer 6 gradually decreases in the direction away from the hydrocolloid dressing 1. An adhesive layer is provided on one side of the anti-curling layer 6, and the adhesive layer of the anti-curling layer 6 is located on the same side as the adhesive layer of the hydrocolloid dressing 1.

[0042] Specifically, this application provides a gradually thinning anti-rolling layer 6 at the edge of the hydrocolloid dressing 1 to enhance the stability of the electrode sheet's adhesion to the skin and prevent the edge of the hydrocolloid dressing 1 from curling up.

[0043] In one possible implementation, the hydrocolloid electrode sheet further includes a release film 7, which is detachably attached to the adhesive layer. The release film 7 provides adhesive protection to the adhesive layer and can be peeled off when needed.

[0044] In one possible implementation, the release film 7 has an arc-shaped recess 71 in the middle, the size of which is adapted to the size of the conductive paste 4.

[0045] Specifically, an arc-shaped recessed area 71 is provided in the middle of the release film 7, and the arc-shaped recessed area 71 is adapted to the conductive paste 4, so as to protect the conductive paste 4 through the arc-shaped recessed area 71.

[0046] In one possible implementation, the hydrocolloid dressing 1 is provided with a plurality of breathable holes 12 spaced apart to increase breathability, allow sweat to evaporate in time, improve patient comfort, and further reduce the risk of skin allergies.

[0047] In one possible implementation, the anti-rolling layer 6 is integrally formed with the hydrocolloid dressing 1.

[0048] In one possible implementation, the conductive paste 4 is made of a flexible conductive material.

[0049] The conductive ointment can be made of materials with good conductivity and uniform impedance to ensure stable transmission of electrical stimulation signals, avoid skin irritation caused by uneven current due to uneven impedance, and improve the stability of treatment effect.

[0050] In one possible implementation, a pulling portion 72 is provided on the outer edge of the release film 7. This allows force to be applied to the pulling portion 72 when it is necessary to tear off the release film 7, so as to easily tear off the release film 7.

[0051] In this application, a hydrocolloid dressing 1 is used to replace the traditional backing adhesive layer, which has good skin affinity and biocompatibility, can absorb exudate, and has little impact on adhesion when exposed to liquids such as sweat.

[0052] The conductive paste is placed around the outer periphery of the conductive electrode and located at the center of the hydrocolloid dressing 1 to improve the reliability of contact with human skin.

[0053] In practical use, first peel off the release liner of the adhesive layer, clean the patient's skin with saline solution, and then apply the hydrocolloid electrode pads to the corresponding treatment area. The external electrotherapy device transmits the electrical stimulation signal to the conductive paste through the electrode clip 5, which then transmits the signal to the patient's skin, enabling electrocardiogram monitoring. The hydrocolloid dressing 1 not only reduces the risk of skin allergies but also absorbs exudate from the skin surface, keeping the skin dry and providing a stable environment for electrotherapy. The outer diameter of the electrode pads ranges from 0.5 mm to 3 mm.
