Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an improved disposable electrode sheet. Background Art

[0002] ECG monitoring instruments include monitor columns, electrodes and ECG monitor leads. ECG electrodes are important devices for recording electrocardiograms (ECGs). They are usually made of conductive materials and are used to contact the patient's skin surface to detect and record the heart's electrical activity. ECG electrodes mainly include: (1) Sensor: used to capture the patient's ECG signals. (2) Conductive glue: located at the bottom of the electrode, used to ensure good skin-electrode contact and conduct electrical signals. (3) Connecting wire: connects the electrode to the ECG instrument or monitoring device. Pre-connected electrode: already pre-fixed with the connecting wire for direct use. Separate electrode: the connecting wire needs to be separated from the electrode and then manually connected. Application scenarios of ECG electrodes: used to record ECGs and perform heart monitoring. Widely used in medical places such as emergency, operating rooms, wards and rehabilitation centers. Working principle of ECG electrodes: the electrode contacts the patient's skin surface, allowing the heart's electrical activity to be transmitted to the ECG recording device, thereby generating an ECG waveform.

[0003] However, existing cardiac electrodes have certain limitations in actual use. For example: First, for patients who need to do dynamic ECG recording, the recording time is relatively long. The current ECG electrodes have poor air permeability, which can easily cause skin allergies or dermatitis on the patient's local skin, reducing the patient's comfort. Some patients will scratch their skin, causing the electrodes to fall off, affecting the test results. Secondly, the electrode is pasted on the human body to play a role in signal sensing and collection. Commonly used electrode sheets in hospitals include a sticker and a connecting button connected to the sticker. The sticker is used to stick to the human body, and the connecting button plays a role in signal sensing and collection. In addition, the connecting button is also connected to the ECG monitor lead, and the connection between the two is usually in the form of a snap. When the patient leaves the ward to go to the toilet or for other reasons, the electrodes and leads need to be separated and reconnected when the patient comes back. The electrodes and leads may need to be separated and reconnected many times a day. The existing connection method requires repeated connection of the electrodes and leads, which is prone to the risk of the electrodes falling off, and medical staff are required to repeatedly connect the electrodes and leads, wasting medical resources. In addition, if the patient connects the electrodes and leads by himself after going to the toilet, it may cause connection errors and affect monitoring, causing danger.

[0004] In view of the above problems, there is an urgent need for an improved disposable electrode sheet that can solve at least one of the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide an improved disposable electrode sheet with good air permeability, which can reduce the user's allergies and can conveniently separate the electrode sheet from the lead when the user needs to go to the toilet or for other reasons, and is also convenient to connect.

[0028] Embodiment 1:

[0029] See also Figure 1 As shown, an improved disposable electrode sheet comprises:

[0030] The electrode sheet comprises a connector 2 and a metal sheet body 1, wherein the connector 2 is used to connect to a lead, and the metal sheet body 1 is used to detect electrical activity of a human heart;

[0031] A fixed patch, the fixed patch includes a hole adapted to the electrode sheet, the electrode sheet connector 2 passes through the hole, the metal sheet body 1 is arranged in the hole, the fixed patch is a multi-layer structure, and includes a first release film 3 layers, an adhesive contact layer 4, a mixed antibacterial layer 5 and a water absorption layer 6 from the inside to the outside in accordance with the contact surface with human skin, the adhesive contact layer 4 is used to adhere the fixed patch to human skin, the mixed antibacterial layer 5 includes a mixture of non-woven fabric and natural herbs, and the water absorption layer 6 is a cotton-nylon blend.

[0032] Furthermore, the adhesive contact layer 4 includes a mixture of silicone and natural rubber.

[0033] Furthermore, the natural herbal mixture is made from a mixture of calendula and chamomile.

[0034] The main function of the first release film 3 is to protect the adhesive contact layer 4. Before use, the adhesive contact layer 4 does not contact with external substances to ensure its adhesive properties. When in use, the first release film 3 is peeled off and the adhesive contact layer 4 is in contact with the human body to adhere the electrode sheet to the human skin; the material of the mixed antibacterial layer 5 is made of non-woven fabric, and the non-woven fabric in the mixed antibacterial layer 5 contains natural herbs. The main function of the herbs is antibacterial and anti-inflammatory. The non-woven fabric is mixed with the herbal mixture to make it have antibacterial effect. Calendula contains a variety of active ingredients, such as flavonoids, sterols, terpenes, etc. It is used to make herbal preparations, herbal oils and herbal ointments, etc., and is often used to treat skin inflammation, eczema, burns, ulcers and skin infections, etc., and has anti-inflammatory, antibacterial and healing stimulating effects; chamomile contains active ingredients such as volatile oils, flavonoids, bitter substances and vitamins. Chamomile is believed to have anti-inflammatory, sedative, digestive and antioxidant effects; the mixed antibacterial layer 5 contains calendula and chamomile ingredients, which protect the skin and have antibacterial and anti-inflammatory effects; the water-absorbing layer 6 is a cotton-nylon blend, which is a blend of polyester and cotton. It has the quick-drying properties of polyester and the moisture absorption properties of cotton, providing a better sweat absorption effect, which can keep the fixed patch dry and is not easy to breed bacteria and cause allergic reactions.

[0035] Furthermore, the water-absorbing layer 6 further includes a plurality of first accommodating cavities 11, and water-absorbing polymers are contained in the first accommodating cavities 11. In order to further make the water-absorbing layer 6 have better water absorption performance, the water-absorbing layer 6 is provided with the first accommodating cavities 11, and water-absorbing polymers are disposed in the accommodating cavities. The water-absorbing polymer materials are generally made of cross-linked polymers, which can absorb hundreds of times their own weight of water and can form gel-like substances. The selection of water-absorbing polymers with good biocompatibility and non-toxicity can improve the water absorption performance of the fixed patch, further ensure the dryness of the applied part, and reduce the reduction of stickiness and the growth of bacteria due to excessive moisture.

[0036] Furthermore, the portion of the electrode sheet in contact with the human body also includes an anti-allergic conductive gel 13 .

[0037] In order to further reduce the allergic phenomenon caused by the electrode, the contact part of the electrode and human skin is made of anti-allergic conductive gel 13. The conductive gel is a mixture of silicone and resveratrol. Silicone is a soft, elastic and high-temperature resistant organic material used to prepare soft conductive gel with good biocompatibility. Resveratrol is a natural compound found in grape skins, wine and some plants. It has obvious anti-inflammatory and antioxidant effects, can inhibit inflammatory reactions and regulate the immune system. The anti-allergic conductive gel 13 can ensure the accuracy of the electrical activity measured by the electrode while having anti-inflammatory and anti-allergic effects.

[0038] Furthermore, the adhesive contact layer 4 further includes a water absorbing portion 10, which is disposed on the outer ring layer of the adhesive contact layer 4, and surrounds the natural rubber adhesive in the adhesive contact layer 4, and the water absorbing portion 10 includes a blend of polyester and cotton.

[0039] The water absorbing part 10 provided on the sticky contact layer 4 is in the outer circle layer of the sticky contact layer 4, which can absorb sweat from other parts of the body and reduce the sweat flowing to the sticky substance of the sticky contact layer 4, thereby reducing the viscosity, thereby causing problems such as electrode sheet falling off and bacterial growth caused by sweat.

[0040] Furthermore, the fixed patch also includes a heating layer 7, and the two surfaces of the heating layer 7 are provided with a second release film 8 and a third release film 9. The heating layer 7 includes a receiving cavity and iron powder, and the iron powder is arranged in the receiving cavity. The heating layer 7 is arranged as the outermost layer of the fixed patch.

[0041] When the metal electrode sheet is in use, its surface temperature is often lower than the human body temperature, so when the electrode sheet is applied, the person to be tested will feel great discomfort due to the electrode sheet being too cold. Therefore, the heating layer 7 is designed to increase the temperature of the electrode sheet before using it, reduce the temperature difference between the electrode sheet and the human body, and thus reduce the discomfort of the person to be tested during use; a second accommodating cavity 12 is arranged in the heating layer 7, and iron powder is arranged in the second accommodating cavity 12. The second release film 8 and the third release film 9 are respectively arranged on both sides of the heating layer 7. When in use, the second release film 8 or the third release film 9 is peeled off, and the iron powder reacts with oxygen in the air to heat the electrode sheet. After heating for a period of time, the heating layer 7 can be separated from the fixed application.

[0042] Furthermore, the connector 2 is hemispherical and further comprises a conductive connector 14 adapted to the connector 2 , and the conductive connector 14 is used to connect to an electrocardiogram monitoring instrument.

[0043] The connector 2 is hemispherical, and is compatible with the lead connector 14, and is connected to the ECG detection instrument through the lead connector 14. When the person to be tested needs to go to the toilet or temporarily leave the ECG detection instrument for other reasons, the connection between the lead connector 14 and the ECG detection instrument can be disconnected. Compared with the direct separation from the lead wire by snaps, it is not directly separated from the electrode patch, thereby reducing the risk of the fixed patch detaching.

[0044] Furthermore, the lead connector 14 also includes a connecting wire 15, and the connecting wire 15 is also provided with a magnetic connector 16, and the magnetic connector 16 is used to connect with the lead of the electrocardiogram detection instrument. The lead connector 14 is provided with a connecting wire 15, and the connecting wire 15 is provided with a magnetic connector 16. The magnetic connector 16 is connected to the lead of the electrocardiogram detection instrument through the magnetic connector 16, and when separation is required, it can be separated more conveniently.

[0045] Furthermore, the magnetic connector 16 is provided with a number for distinguishing the location where the electrode sheet is applied.

[0046] During ECG testing, it is often necessary to connect multiple electrodes to an ECG monitoring device. By providing the numbering of the magnetic connectors 16 , the related lead wires can be reconnected relatively quickly after being disconnected in the middle.

[0047] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
