Description

Technical Field

[0001] This utility model relates to the field of electrode patch technology, and in particular to an electrocardiogram electrode patch. Background Technology

[0002] ECG electrode patches are important medical devices used to detect human electrocardiogram (ECG) signals. The human heart generates weak bioelectrical signals during activity, and the ECG electrode patch transmits these signals to ECG monitoring equipment through contact with the skin surface. Its principle is based on the electrochemical interface between the electrode and the skin. When the electrode is attached to the skin, a half-cell is formed between the electrode and the skin. Due to the potential difference generated by the heart's electrical activity, current flows at the electrode-skin interface, which is then detected and transmitted by the electrode. Existing electrode patches are susceptible to external electromagnetic interference in complex electromagnetic environments, such as around various medical equipment in hospitals or near electronic devices in daily life, thus affecting the accuracy of measurements. Furthermore, during human activity, the electrode patch may loosen or shift, especially near joints or skin folds. This can lead to poor contact between the electrode and the skin, affecting the quality of ECG signal acquisition. Based on these issues, a new ECG electrode patch was designed. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides an electrocardiogram (ECG) electrode patch. The adhesive layer allows direct contact with the skin, fixing the electrode patch to the skin and maintaining good contact between the electrode layer and the skin. Furthermore, the shielding layer and isolation layer isolate the electrode from the external electromagnetic environment and prevent chemical corrosion of the electrode by the adhesive components, ensuring a good shielding effect.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] An electrocardiogram (ECG) electrode patch includes: an electrode layer made of silver-silver chloride electrode material; an adhesive layer with a first clearance groove for avoiding the electrode layer; an isolation layer disposed between the electrode layer and the adhesive layer; a padding layer disposed on the side of the adhesive layer away from the electrode layer; a shielding layer disposed on the side of the adhesive layer away from the padding layer; and a base film layer disposed on the side of the shielding layer away from the adhesive layer.

[0006] By adopting the above scheme, the adhesive layer can directly contact the skin to fix the electrode patch to the skin, ensuring good contact between the electrode layer and the skin. Furthermore, the shielding layer and the isolation layer protect the electrode from the external electromagnetic environment and prevent the adhesive components from chemically corroding the electrode, ensuring a good shielding effect. In addition, the Ag-AgCl electrode has good conductivity and electrochemical stability, which can effectively reduce electrode polarization and improve signal quality.

[0007] Furthermore, the diameter of the padding layer is larger than the diameter of the adhesive layer.

[0008] By adopting the above method, it is easy to find the edge of the padding layer and to separate it from the adhesive layer.

[0009] Furthermore, the padding layer is made of non-woven fabric.

[0010] By adopting the above solution, the non-woven fabric is soft and comfortable, which can protect the electrode patch from contamination when not in use, while increasing the comfort of skin contact when in use.

[0011] Furthermore, the shielding layer is made of copper foil.

[0012] By adopting the above scheme, copper foil has good conductivity, which can effectively shield external electromagnetic interference and ensure the purity of electrocardiogram signals.

[0013] Furthermore, an insulating buffer layer is coated between the shielding layer and the adhesive layer.

[0014] By adopting the above solution, the insulating buffer layer prevents the shielding layer from contacting the human body and causing a short circuit, while also enhancing the overall structural stability of the patch.

[0015] Furthermore, the electrode layer is also connected to a wire, and the adhesive layer is also provided with a second clearance groove for avoiding the wire.

[0016] By adopting the above scheme, and by setting up wires to facilitate connection with electrocardiogram monitoring equipment, the monitoring effect can be achieved.

[0017] Furthermore, the base film layer is made of PU film or PE film.

[0018] By adopting the above method, the surfaces of PU films and PE films are smooth and their chemical properties are stable.

[0019] Furthermore, the padding layer is coated with an anti-stick coating that has the same area as the adhesive layer.

[0020] By adopting the above solution and setting an anti-stick coating, the padding layer can be easily peeled off before use without leaving any paper scraps or other impurities. Attached Figure Description

[0028] See Figures 1-2This utility model discloses an electrocardiogram (ECG) electrode patch, comprising an electrode layer 1, an adhesive layer 2, an insulating layer 3, a padding layer 4, a shielding layer 5, and a base film layer 6. The adhesive layer 2 has a first clearance groove for avoiding the electrode layer 1. The insulating layer 3 is disposed between the electrode layer 1 and the adhesive layer 2. The padding layer 4 is disposed on the side of the adhesive layer 2 away from the electrode layer 1. The shielding layer 5 is disposed on the side of the adhesive layer 2 away from the padding layer 4. The base film layer 6 is disposed on the side of the shielding layer 5 away from the adhesive layer 2. The adhesive layer 2 allows direct contact with the skin, fixing the electrode patch to the skin and maintaining good contact between the electrode layer 1 and the skin. The shielding layer 5 and the insulating layer 3 protect the electrode from the external electromagnetic environment and prevent chemical corrosion of the electrode by the adhesive components, ensuring a good shielding effect.

[0029] The isolation layer 3 is an isolation trench to prevent the adhesive components from chemically corroding the electrodes.

[0030] In this embodiment, the electrode layer 1 is made of silver-silver chloride electrode material. Silver-silver chloride electrodes have good conductivity and electrochemical stability, which can effectively reduce electrode polarization and improve signal quality. In some embodiments, to further enhance the signal acquisition effect, a nanoporous structure can be prepared on the surface of the silver-silver chloride to further increase the contact area between the electrode and the skin; wherein, the electrode layer 1 is circular in shape.

[0031] In this embodiment, the base film layer 6 is bonded and fixed to the shielding layer 5, the shielding layer 5 is bonded and fixed to the insulating buffer layer 7, and the insulating buffer layer 7 is bonded and fixed to the adhesive layer 2.

[0032] In this embodiment, the diameter of the padding layer 4 is larger than the diameter of the adhesive layer 2, making it easier to locate the edge of the padding layer 4 and to separate it from the adhesive layer 2. Specifically, the padding layer 4 is made of non-woven fabric, which is soft and comfortable, protecting the electrode patch from contamination when not in use and increasing comfort when in contact with the skin during use. Furthermore, in this embodiment, the padding layer 4 is coated with an anti-stick coating of the same area as the adhesive layer 2.

More specifically, the anti-stick coating is a silicone oil coating.

[0033] In this embodiment, the adhesive layer 2 is made of medical silicone gel. Medical silicone gel has high affinity with the skin and is less likely to cause allergic reactions. At the same time, it allows the skin to breathe and reduces discomfort caused by prolonged adhesion.

[0034] The shielding layer 5 is made of aluminum foil, while copper foil has good conductivity, effectively shielding against external electromagnetic interference and ensuring the purity of the electrocardiogram signal. In this fourteenth embodiment, the surface of the aluminum foil is coated with an anti-oxidation film, more specifically a nickel film, to improve the stability and service life of the shielding layer 5. An insulating buffer layer 7 is coated between the shielding layer 5 and the adhesive layer 2.
