Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an electrocardiogram electrode sheet. Background Art
[0002] ECG electrode patch is a tool for collecting and conducting ECG signals. It is applied to the surface of human skin, and monitors the changes in the surface potential of the human body to feedback the activity of the heart, and transmits it to the electrocardiograph through the wire. Traditional electrode patches are usually coated with an adhesive layer on the backing material to be adsorbed on the human body, but the traditional backing material is mostly non-woven fabric, which can easily cause skin allergies, redness and other discomforts to patients with high sensitivity, especially to some young children with delicate skin. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide an ECG electrode sheet with a reasonable structure, less skin irritation and improved comfort of use.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] An electrocardiogram electrode sheet comprises a substrate and an electrode arranged in the middle of the substrate, characterized in that one side of the substrate is coated with a hydrocolloid dressing layer, the electrode comprises a bottom buckle and a sub-buckle, the bottom buckle passes through the substrate and the hydrocolloid dressing layer and is fixedly buckled with the sub-buckle; and the side of the bottom buckle facing away from the sub-buckle is covered with a biological ion gel layer.
[0006] The hydrocolloid dressing is made by mixing sodium carboxymethyl cellulose (CMC) and rubber elastomer; CMC is a hydrophilic polymer material that has the ability to absorb wound exudate and provide a moist environment that is conducive to wound healing; it has good skin affinity, and coating a hydrocolloid dressing layer on the substrate can reduce the irritation of the electrode to the skin, thereby improving the comfort of use. In addition, the bio-ion gel layer has little or no irritation to the skin, which can effectively improve the comfort of wearing. At the same time, the bio-ion gel layer itself has a certain viscosity, which can ensure close contact between the skin and the electrode, and does not contain volatile solvents, and will not dry out as the wearing time increases, which can ensure the accuracy of the signal transmitted when the ECG electrode patch is worn for a long time.
[0007] Furthermore, the hydrocolloid dressing layer includes hydrocolloid dressing areas arranged in a fan shape, and a plurality of the hydrocolloid dressing areas are evenly distributed at intervals along the circumference of the electrode; and a transparent adhesive is coated on the substrate between two adjacent hydrocolloid dressing areas.
[0008] In this way, the transparent adhesive between two adjacent hydrocolloid dressing areas can increase the adhesion performance of the electrode sheet, reduce the risk of falling off, and thus ensure the reliability of monitoring. In addition, since the transparent adhesive and the hydrocolloid dressing area are arranged at intervals, when replacing the electrode sheet, the positions of the two electrode sheets can be circumferentially displaced, so that the hydrocolloid dressing area of the electrode sheet is attached to the position where the transparent adhesive was last placed, and the skin of that part can also be repaired.
[0009] Furthermore, the substrate is made of transparent material.
[0010] In this way, a transparent observation window can be formed between two adjacent hydrocolloid dressing areas, which is convenient for observing the skin condition so as to replace the electrode sheet in time and improve the quality of care.
[0011] Furthermore, the central angle corresponding to the hydrocolloid dressing area is greater than the central angle between two adjacent hydrocolloid dressing areas.
[0012] In this way, when the electrode sheets are misaligned for two times, it can be ensured that the hydrocolloid dressing area can completely cover the previous adhesive area.
[0013] Furthermore, the substrate is circular and has a handle extending radially outward.
[0014] In this way, the protruding handle can better indicate the pasting angle, making it convenient to determine the direction of the next electrode pasting.
[0015] Furthermore, the substrate has evenly distributed ventilation holes.
[0016] Furthermore, the diameter of the air holes is 1 to 3 mm.
[0017] Furthermore, a flexible electrode layer is provided between the bottom buckle and the substrate, the area of the flexible electrode layer is larger than the area of the bottom buckle, and the bio-ion gel layer is coated on the bottom buckle and the flexible electrode layer.
[0018] In this way, the contact area between the electrode and the skin can be increased, thereby improving the accuracy and reliability of signal collection.
[0019] In summary, the utility model has the advantages of reasonable structure, less irritation to the skin, and the ability to improve comfort in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described in detail below in conjunction with the embodiments.
[0024] When implementing: Figure 1 to Figure 3 As shown, an ECG electrode sheet comprises a substrate 1 and an electrode 2 arranged in the middle of the substrate 1, one side of the substrate 1 is coated with a hydrocolloid dressing layer 3, the electrode 2 comprises a bottom buckle 21 and a sub-button 22, the bottom buckle 21 passes through the substrate 1 and the hydrocolloid dressing layer 3, and is fixedly buckled with the sub-button 22; the side of the bottom buckle 21 away from the sub-button 22 is covered with a bio-ion gel layer 4, a flexible electrode layer 5 is arranged between the bottom buckle 21 and the substrate 1, the area of the flexible electrode layer 5 is larger than that of the bottom buckle 21, and the bio-ion gel layer 4 is coated on the bottom buckle 21 and the flexible electrode layer 5. The contact area between the electrode and the skin can be increased, thereby improving the accuracy and reliability of signal collection.
[0025] The hydrocolloid dressing is made by mixing sodium carboxymethyl cellulose (CMC) and rubber elastomer; CMC is a hydrophilic polymer material that has the ability to absorb wound exudate and provide a moist environment that is conducive to wound healing; it has good skin affinity, and coating a hydrocolloid dressing layer on the substrate can reduce the irritation of the electrode to the skin, thereby improving the comfort of use. In addition, the bio-ion gel layer has little or no irritation to the skin, which can effectively improve the comfort of wearing. At the same time, the bio-ion gel layer itself has a certain viscosity, which can ensure close contact between the skin and the electrode, and does not contain volatile solvents, and will not dry out as the wearing time increases, which can ensure the accuracy of the signal transmitted when the ECG electrode patch is worn for a long time.
[0026] like Figure 3 As shown, the substrate 1 is made of transparent material, the hydrocolloid dressing layer 3 includes hydrocolloid dressing areas arranged in a fan shape, and a plurality of hydrocolloid dressing areas are evenly distributed along the circumference of the electrode 2 at intervals; the substrate 1 between two adjacent hydrocolloid dressing areas is coated with transparent adhesive.
[0027] In this way, the transparent adhesive between two adjacent hydrocolloid dressing areas can increase the adhesion performance of the electrode sheet, reduce the risk of falling off, and thus ensure the reliability of monitoring. In addition, since the transparent adhesive and the hydrocolloid dressing area are arranged at intervals, when replacing the electrode sheet, the positions of the two electrode sheets can be circumferentially displaced, so that the hydrocolloid dressing area of the electrode sheet is attached to the position of the last transparent adhesive, and the skin of this part can also be repaired. By using a transparent material to make a substrate, a transparent observation window can be formed between two adjacent hydrocolloid dressing areas, which is convenient for observing the skin condition, so as to replace the electrode sheet in time and improve the quality of care. During implementation, the central angle corresponding to the hydrocolloid dressing area is greater than the central angle between the two adjacent hydrocolloid dressing areas. In this way, when the electrode sheets are misplaced twice, it can be ensured that the hydrocolloid dressing area can completely cover the adhesive area of the last time.
[0028] like Figure 2 As shown, the substrate 1 is circular and has a gripping handle 11 extending radially outward. The substrate 1 has evenly distributed vent holes 12, and the diameter of the vent holes 12 is 1 to 3 mm. In this way, the protruding gripping handle can better indicate the pasting angle, and it is convenient to determine the direction of the next electrode sheet pasting.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
