Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an antibacterial impedance cardiogram electrode sheet that resists tissue deformation. Background Art
[0002] Electrocardiogram electrodes are an important consumable used in medical processes such as electrocardiogram testing and ECG monitoring. They are mainly attached to the patient's skin and connected to the electrocardiograph to collect and transmit the heart's electrical signals, thereby forming an electrocardiogram waveform on the electrocardiograph for doctors to perform diagnostic analysis.
[0003] Impedance cardiography is a non-invasive method for detecting cardiac hemodynamics. By measuring the potential difference on the chest surface, impedance cardiography can indirectly measure the chest impedance, and analysis and processing can obtain hemodynamic parameters. This method is currently mainly used for real-time monitoring of hemodynamic parameters during exercise. Patients undergoing impedance cardiography examinations have large individual differences in body shape. In addition, a considerable number of subjects have undergone heart surgery and have scars on their chests. Traditional patches are difficult to meet individual needs, and the electrodes are not firmly attached. At the same time, the subjects are more likely to fall off during exercise due to tension or sweating during exercise. The electrodes often fall off and become loose, resulting in poor reception of ECG signals and affecting the test results. Sometimes a single examination of a patient requires at least 8 electrodes, which is a high resource consumption.
[0004] The human body has a long-term resident microbial community. To avoid cross-infection, most ECG patches are currently disposable, which increases the cost of examinations and causes unnecessary waste.
[0005] Currently, disposable ECG electrodes are commonly used in clinical practice. The portion of the electrodes that come into contact with the subject is made of medical adhesive. Some subjects experience medical adhesive-related skin damage during examinations, manifesting as itching, erythema, papules, blisters, and even epidermolysis and skin necrosis. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1As shown, an antibacterial impedance cardiography electrode sheet with resistance to tissue deformation includes a metal connecting buckle 3, a composite hydrogel layer 1 bonded to the bottom of the metal connecting buckle 3, a conductor 2 provided at the edge of the bottom of the metal connecting buckle 3, a release film 4 bonded to the upper surface of the bottom of the metal connecting buckle 3, a fabric electrode 5 provided at the edge of the release film 4, and a protective film covering the lower surface of the composite hydrogel layer 1;
[0023] The conductor 2 and the metal connecting buckle 3 are located on the composite hydrogel layer 1, and the conductor 2 is located around the metal connecting buckle 3;
[0024] The upper surface of the conductor 2 is bonded to the release film 4 and the lower surface of the fabric electrode 5 .
[0025] Medical staff remove the protective film covering the surface of the composite hydrogel layer 1 and stick the electrode body on the appropriate position of the examinee according to the examination needs; the composite hydrogel layer 1 directly contacts the examinee's skin, TCP has good conductivity, and the ECG signal can be well transmitted to the conductor 2 and the metal connecting buckle 3; the conductor 2 and the metal connecting buckle 3 receive the ECG signal and transmit it to the release film 4 and the fabric electrode 5; the release film 4 and the fabric electrode 5 lead the ECG signal to the metal connecting buckle 3; the non-invasive cardiac output monitor is connected to the metal connecting buckle 3 of the electrode through the lead wire, thereby realizing real-time transmission of the ECG signal.
[0026] Composite hydrogel layer 1 is a composite hydrogel (TCP) embedded iodine nanosheet layer;
[0027] It has the characteristics of broad antibacterial spectrum, strong antibacterial ability, long half-life (can continuously release antibacterial active substances) and little damage to tissues.
[0028] The composite hydrogel-embedded nanosheet layer consists of TCP and iodine nanosheets. The iodine nanosheets are uniformly embedded in TCP, and the size of a single iodine nanosheet is at the nanometer level.
[0029] It does not affect the electrical conductivity, tissue adhesion and shaping ability of TCP, while achieving its antibacterial effect.
[0030] The shape of the electrode sheet is not limited and is divided into three layers from top to bottom.
[0031] The working principle of the present invention is as follows: a composite hydrogel (TCP) is covered on the outside of the conductive layer to embed an iodine nanosheet layer. The polyvinyl alcohol-sodium alginate-tannic acid-borax composite hydrogel (TCP) has good tissue adhesion, tissue compatibility and shaping ability, which can solve the problem of electrode sheets being difficult to fix due to shedding during the test of the subject, allergies induced by contact with the electrode sheet, and differences in the body shape of the subjects and surgical scars of some postoperative recovery patients. At the same time, in order to prevent cross-infection between different patients, the electrodes currently used are mostly disposable electrodes, which results in increased testing costs and unnecessary waste. Iodine nanosheets have the characteristics of a broad antibacterial spectrum, strong antibacterial ability, a long half-life (can continuously release antibacterial active substances) and low damage to tissues. Composite hydrogel (TCP) embedded iodine nanosheets have become an ideal material for preparing electrode sheets;
[0032] When performing an impedance cardiogram, medical staff remove the protective film covering the surface of the composite hydrogel layer 1 and stick the electrode body on the appropriate position of the subject according to the examination needs. The composite hydrogel layer 1 directly contacts the subject's skin, and TCP has good conductivity, so the ECG signal can be well transmitted to the conductor 2 and the metal connector 3; the conductor 2 and the metal connector 3 receive the ECG signal and transmit it to the release film 4 and the fabric electrode 5. The release film 4 and the fabric electrode 5 lead the ECG signal to the metal connector 3; the non-invasive cardiac output monitor is connected to the metal connector 3 of the electrode through the lead wire, thereby realizing real-time transmission of the ECG signal;
[0033] During the test, the iodine nanosheets in the composite hydrogel layer 1 continuously release antibacterial active substances to fight against various pathogens transferred from the subject to the composite hydrogel layer 1;
[0034] After the test is completed, the medical staff removes the electrode sheet from the subject and replaces the protective film on the surface of the composite hydrogel layer 1.
[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
