Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and in particular, to an electrocardiograph electrode sheet. Background Art

[0002] An electrocardiograph is a medical device used to record and analyze the electrical activity of the heart. When in use, medical staff need to clamp the limb lead clips on the patient's limbs and attach the chest lead adsorption balls to the patient's chest. After the limb lead clips and the chest lead adsorption balls are fixed in the correct position, the lead clips and the adsorption balls transmit electrical signals to the electrocardiograph, so that the electrocardiograph can record and display the electrical activity of the heart, thereby helping doctors to diagnose and monitor. However, in actual operation, medical staff found that for patients with special body shapes, the limb lead clips and the chest lead adsorption balls cannot be well fixed on the patients, resulting in the inability to perform electrocardiogram tests on the patients. That is, for obese patients, the limb lead clips cannot be firmly clamped on their limbs, and for thin patients, the chest lead adsorption balls cannot be firmly attached to their chests. When the limb lead clips and the chest lead adsorption balls cannot be firmly fixed on the patients, the clarity and readability of the electrocardiogram will be affected, thereby increasing the risk of misdiagnosis by doctors.

DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In a specific embodiment of the present disclosure, an electrocardiograph electrode sheet is provided, referring to Figures 1 to 4As shown, the electrocardiograph electrode sheet comprises: a flexible film 1 and an electrode sheet 2, wherein the electrode sheet 2 comprises an electrode terminal 201 and a connection terminal 202 which are fixedly connected, wherein the flexible film 1 is provided with a through hole 101 for the connection terminal 202 to pass through, and an adhesive layer for adhering to the electrode terminal 201 is provided on the end surface of the flexible film 1 away from the connection terminal 202, and the adhesive layer is also used for adhering to the patient's skin, when the flexible film 1 and the electrode sheet 2 are adhered and fixed to the patient's skin through the adhesive layer, the electrode terminal 201 of the electrode sheet 2 contacts the patient's skin, that is, the electrode sheet 2 is adhered to the skin through the adhesive layer, and senses the electrical activities of the heart, which are formed by the potential changes generated by the depolarization and repolarization processes of the myocardial cells, and each electrode sheet 2 is connected to the electrocardiograph through the electrocardiograph lead wire, collects and transmits these weak electrical signals, and then the collected electrical signals are processed by the electrocardiograph. The electrical signal is amplified, filtered and converted to generate a visual electrocardiogram waveform, which helps doctors evaluate and diagnose various heart-related diseases. At the same time, in order to optimize the operating process and improve the detection efficiency of medical staff, the end of the connection end 202 of the electrode sheet 2 away from the electrode end 201 is provided with a slot 2021 for plugging in the electrocardiograph lead wire connector. That is, when an electrocardiogram detection operation is required for the patient, the electrode sheet 2 needs to be connected to the electrocardiograph lead wire first. In order to improve work efficiency, a slot 2021 for plugging in the electrocardiograph lead wire connector can be provided at the end of the connection end 202 of the electrode sheet 2. The electrode sheet 2 is fixedly connected to the electrocardiograph lead wire by plugging, and the internal structure of the slot 2021 matches the electrocardiograph lead wire connector, which is convenient for medical staff to insert the electrocardiograph lead wire connector into the slot 2021.

[0029] Through the above technical scheme, the electrode sheet 2 is used to replace the limb lead clips and the chest lead adsorption ball to connect the electrocardiograph, so that medical staff do not need to consider the limitations of the use of the limb lead clips and the chest lead adsorption ball (for obese patients, the limb lead clips cannot be firmly clamped on their thick limbs, resulting in poor electrode contact and unstable signal transmission; for thin patients, the chest lead adsorption ball cannot be firmly adsorbed on their relatively flat or concave chest position, resulting in the electrode easily falling off, affecting signal acquisition), that is, a slot 2021 for plugging in the lead wire connector of the electrocardiograph is provided at the connection end 202 of the electrode sheet 2. When the patient needs to perform an electrocardiogram test, the medical staff can quickly and efficiently complete the connection between the electrode sheet 2 and the lead wire connector of the electrocardiograph, and stick the electrode sheet 2 connected with the lead wire connector of the electrocardiograph to various positions of the patient's body by pasting, so that the medical staff can efficiently perform electrocardiogram testing operations while ensuring the accuracy of the test results.

[0030] At the same time, after each electrocardiogram test is completed, the electrode sheet 2 is replaced to avoid cross infection and poor signal conduction.

[0031] In some embodiments, reference Figure 1 and Figure 2 As shown, in order to improve the signal conduction efficiency, the electrode end 201 may be covered with a conductive gel 3, which is used to reduce the resistance between the skin and the electrode to ensure the conduction of electrical signals.

[0032] In some embodiments, reference Figure 1 and Figure 2 As shown, in the electrocardiogram detection, in order to ensure that the electrode sheet 2 can provide stable signal conduction during use and protect the integrity of the conductive gel 3 and the adhesive layer, it can be protected by a protective cover 4, that is, the protective cover 4 has a substrate 401 for bonding the adhesive layer and a storage cover 402 for storing the conductive gel 3. The substrate 401 is bonded to the adhesive layer of the electrode sheet 2 to prevent the adhesive layer from contacting the air, dust or other pollutants to maintain its viscosity. The storage cover 402 covers the conductive gel 3 to prevent the conductive gel 3 from drying, hardening or being contaminated during storage. At the same time, the storage cover 40 2 has good sealing performance, which helps to maintain the humidity of the conductive gel 3 and ensure that it can conduct electricity well when used. When the electrode sheet 2 is needed for electrocardiogram detection, on the basis of the electrode sheet 2 being connected to the electrocardiograph lead wire, the medical staff tears off the protective cover 4, so that the adhesive layer of the electrode sheet 2 and the conductive gel 3 are exposed to the air. When tearing off the protective cover 4, the medical staff must ensure that the adhesive layer is not touched during the operation to avoid affecting its viscosity. Then, the electrode sheet 2 is attached to the patient's chest and limbs at specific positions according to the requirements of the electrocardiogram detection, and the electrocardiogram detection can be performed after the attachment is completed.

[0033] In some embodiments, reference Figure 1 and Figure 2 As shown, in order to facilitate medical staff to tear off the lower protective cover 4 efficiently and conveniently, an isolation area 5 is provided at the edge of the flexible film 1 located at the adhesive layer, that is, when the electrode sheet 2 is not in use, the adhesive layer and the substrate 401 are in a bonded state. In order to facilitate medical staff to tear off the lower protective cover 4, an isolation area 5 can be provided at the edge of the adhesive layer, and the isolation area 5 will not be bonded to the substrate 401, wherein the adhesive layer can be formed by applying an adhesive on the end surface of the flexible film 1 away from the connection end 202, and the isolation area 5 can be formed by cutting a material of the same material as the flexible film 1 and pasting it on the edge of the adhesive layer, or the edge of the end surface of the flexible film 1 away from the connection end 202 is not coated with adhesive.

[0034] In some embodiments, reference Figure 1 and Figure 2As shown, the edge contour of the isolation area 5 is annular, that is, when the electrode sheet 2 is attached to the patient's skin, the edge of the flexible film 1 has no adhesive layer, so that medical staff can more conveniently peel off the flexible film 1 with the electrode sheet 2 attached when finishing the electrocardiogram test, reducing the pulling and discomfort to the patient's skin. At the same time, the edge area without the adhesive layer will not leave sticky residue after peeling off, keeping the patient's skin clean and reducing the cleaning work. In addition, due to the provision of the isolation area 5, the contact area between the adhesive layer and the patient's skin is reduced, reducing the risk of skin irritation and allergic reaction of the patient, and increasing the comfort of the patient.

[0035] In some embodiments, reference Figure 3 and Figure 4 As shown, the electrocardiograph lead wire connector and the connecting end 202 of the electrode sheet 2 can also be connected with the help of the connecting column 6. That is, during the actual operation of the medical staff, due to the small size of the slot 2021, the medical staff needs to align the electrocardiograph lead wire connector and the slot 2021 before plugging them in. In order to simplify the operation of the medical staff, the connecting column 6 can be used as a medium to connect the two. The material of the connecting column 6 is the same as that of the electrode sheet 2 to ensure the effectiveness of signal transmission. At the same time, a first jack 601 for plugging the electrocardiograph lead wire connector and a second jack 602 for plugging the connecting end 202 are provided in the connecting column 6. The medical staff can Before performing the ECG detection operation, the connecting column 6 is installed in advance on the ECG lead wire connector (the ECG lead wire connector is inserted into the first jack 601). When the electrode sheet 2 needs to be connected, only the connecting end 202 of the electrode sheet 2 needs to be inserted into the second jack 602. Similarly, when the electrode sheet 2 needs to be replaced, there is no need to separate the ECG lead wire connector from the connecting column 6. Therefore, using the connecting column 6 as a medium for connecting the ECG lead wire connector and the electrode sheet 2 can effectively reduce the number of times the ECG lead wire connector is directly plugged in and out, reduce the wear of the ECG lead wire connector, and increase the service life of the ECG lead wire connector.

[0036] In some embodiments, reference Figure 3 and Figure 4 As shown, in order to improve safety, an insulating sleeve 7 is sleeved on the outside of the connecting column 6, and the insulating sleeve 7 can effectively prevent current leakage, reduce the risk of electric shock to patients and medical staff, and ensure safety during the detection process. At the same time, it can also prevent the connecting column 6 from contacting other metal objects, avoid the occurrence of short circuits, and ensure the normal operation of the electrocardiogram equipment. The insulating sleeve 7 can also protect the connecting column 6 from mechanical wear and extend the service life of the connecting column 6.

[0037] In some embodiments, the insulating sleeve 7 can be made of anti-slip material, thereby providing the medical staff with a good grip feeling, facilitating the medical staff to hold the connecting column 6 more firmly during operation, thereby reducing the risk of misoperation.

[0038] In some embodiments, reference Figure 4 As shown, in order to improve the connection strength between the connection end 202 of the electrode sheet 2 and the connection column 6, a rubber ring 6021 can be further provided on the inner wall surface of the second jack 602. When the connection column 6 is inserted into the second jack 602, the rubber ring 6021 is in interference contact with the side wall surface of the connection end 202, ensuring that the connection end 202 and the connection column 6 will not loosen or separate during use, thereby improving the structural stability and ensuring that the signal can be transmitted stably. Similarly, a rubber ring 6021 can also be provided in the first jack 601 to enhance the connection strength between the connection column 6 and the lead wire connector of the electrocardiograph.

[0039] In some embodiments, reference Figure 4 As shown, in order to further improve the connection strength between the connecting column 6 and the connecting end 202, a rod 9 for plugging into the slot 2021 can be provided on the bottom surface of the second socket 602 on the basis of the slot 2021, that is, when the connecting end 202 is inserted into the second socket 602, the rod 9 is inserted into the slot 2021. The connection between the rod 9 and the slot 2021 can improve the connection strength between the connecting column 6 and the connecting end 202, and double fixation is achieved in combination with the rubber ring 6021. At the same time, the cooperation between the rod 9 and the slot 2021 ensures that the connecting end 202 is not easy to loosen during use, thereby maintaining the stability and continuity of signal transmission.

[0040] In some embodiments, reference Figure 3 and Figure 4 As shown, in order to make the connection column 6 and the connection end 202 smoother during the plugging and unplugging process, a ring block 8 can be provided at the end of the connection end 202 away from the electrode end 201, and both ends of the ring block 8 are provided with an arc surface 801. During the plugging and unplugging process, the arc surface 801 with a smooth surface and a certain curvature reduces the friction resistance between the connection end 202 and the inner wall of the second socket 602, thereby making the connection end 202 smoother when inserted and unplugged from the second socket 602.

[0041] Description of the usage process of the electrode sheet 2: When it is necessary to perform an electrocardiogram test on the patient, the connecting column 6 can be plugged into the lead wire connector of the electrocardiograph before the test, and then the second socket 602 of the connecting column 6 can be aligned with the connecting end 202 of the electrode sheet 2 for plugging. After the plugging is completed, the protective cover 4 attached to the adhesive layer is torn off, so that the adhesive layer and the conductive gel 3 of the electrode sheet 2 are exposed to the air. After that, the electrode sheet 2 is attached to the specific positions of the patient's chest and limbs according to the requirements of the electrocardiogram test, and the electrocardiogram test can be performed after the attachment is completed.
