[0002] An AED (Automated External Defibrillator) is a medical device used to rescue patients with cardiac arrest. Usually, during the use of an AED, two electrode sheets need to be attached to the predetermined positions on the patient's body. The device collects the patient's electrocardiogram (ECG) signals through the two electrode sheets, analyzes the patient's ECG signals, and determines whether the patient is suitable for defibrillation by electric shock.

[0003] A cardiopulmonary resuscitation simulator is a teaching tool created using medical simulation technology, which can be used to simulate clinical scenarios and patients, and replace real patients for clinical teaching and educational practice. Conducting medical model teaching can improve the practical hands-on ability of trainees, effectively solve the problem of "emphasizing theory over practice", and is of great significance for training medical rescue personnel.

[0004] When conducting medical model teaching of cardiopulmonary resuscitation, training medical rescue personnel to accurately attach two electrode sheets to the set positions on the simulator is one of the important training objectives. However, the existing electrode sheets are prone to warping during use, resulting in possible detachment of the electrode sheets during training teaching, thereby affecting the progress of training teaching. Summary of the Utility Model

[0005] Based on this, in view of the problem that the electrode sheets are prone to warping and falling off, it is necessary to provide an electrode sheet assembly of a defibrillation training device and a defibrillation training device.

[0006] An electrode sheet assembly of a defibrillation training device includes a first electrode sheet and a second electrode sheet, and NFC induction modules are respectively arranged on the first electrode sheet and the second electrode sheet, and the NFC induction modules are used for transmitting and / or receiving radio signals.

[0007] In one embodiment, the NFC induction module includes an antenna, and the antenna forms a coil structure with a hollow interior.

[0008] In one embodiment, the shape of the coil structure includes but is not limited to a circle, an ellipse, a sector, a triangle, and a polygon.

[0009] In one embodiment, the NFC induction module further includes a flexible circuit board, a first conductive sheet, and a second conductive sheet. The antenna, the first conductive sheet, and the second conductive sheet are all formed on the surface of the flexible circuit board. The first end of the antenna is connected to the first conductive sheet, and the second end of the antenna is connected to the second conductive sheet.

[0010] In one embodiment, the NFC induction module further includes a reinforcing plate, and the reinforcing plate is disposed on the flexible circuit board in a region corresponding to the first conductive sheet and the second conductive sheet.

[0011] In one embodiment, the NFC induction module is connected to the connection terminals of an external cable through the first conductive sheet and the second conductive sheet.

[0012] In one embodiment, the bodies of the first electrode sheet and the second electrode sheet both include an insulating base layer and an insulating adhesive layer, and the NFC induction module is disposed between the insulating base layer and the insulating adhesive layer.

[0013] In one embodiment, the first electrode sheet and the second electrode sheet further include a protective layer.

Detailed implementation manners

[0026] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to understand the disclosure of the present invention more thoroughly and comprehensively.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] When conducting medical model teaching of cardiopulmonary resuscitation, training medical rescue personnel to accurately attach two electrode pads to the set positions on the mannequin is one of the important training objectives. Figure 1 It is a schematic structural diagram of an electrode pad in the prior art. In the existing technical solution, a Hall sensor is arranged on the surface of the mannequin's chest cavity, and a coil arranged in a spiral shape is arranged inside the electrode pad. The coil in the electrode pad and the Hall sensor form an induction magnetic field to determine whether the attachment position of the electrode pad on the mannequin is accurate. However, the spiral coil arranged in the electrode pad in the prior art results in a large thickness and small elasticity of the electrode pad, thereby causing a poor fit between the electrode pad and the mannequin and easily causing problems such as warping and falling off.

[0029] This application provides an electrode pad assembly for a defibrillation training device with a small thickness and a simple structure. Figure 2 It is a schematic structural diagram of an electrode pad assembly of a defibrillation training device in one embodiment of this application. In one embodiment, the electrode pad assembly of the defibrillation training device may include a first electrode pad 100 and a second electrode pad 200. NFC induction modules 300 may be respectively arranged on the first electrode pad 100 and the second electrode pad 200. The first electrode pad 100 and the second electrode pad 200 may respectively use the NFC induction modules 300 to transmit and / or receive radio signals.

[0030] One or more NFC tags may be arranged on the surface of the chest cavity position of the mannequin in the defibrillation training device. When the first electrode pad 100 and / or the second electrode pad 200 move to the induction area of the NFC tag, the first electrode pad 100 and / or the second electrode pad 200 can communicate with the NFC tag on the mannequin, and data exchange and transmission can be realized between the NFC induction module 300 on the first electrode pad 100 and / or the second electrode pad 200 and the NFC tag on the mannequin based on magnetic field coupling.

[0031] In the prior art, the position detection unit integrated in the electrode sheet is based on the Hall effect and is realized by detecting the magnetic field change using a Hall sensor arranged on the surface of the human body model. The Hall sensor requires a current to flow through a semiconductor material and generates a voltage difference in a direction perpendicular to the current and the magnetic field, thereby measuring the magnetic field strength. Therefore, the Hall sensor usually includes structures such as a magnetic field sensitive element, an amplification circuit, and a temperature compensation element. It can be seen that a certain physical size is required to accommodate the Hall sensor element and the necessary electronic circuits when applying the Hall sensor.

[0032] NFC (Near Field Communication) technology is a short-distance high-frequency wireless communication technology. Devices integrated with NFC chips can perform energy and data transmission through a non-radiative electromagnetic field when they are close to each other. The effective communication distance of NFC technology is usually several centimeters. Therefore, the components related to NFC communication technology can be designed to be very small. It can be seen that the structure of the NFC induction module 300 provided in this application is simpler than the structure of the position detection unit in the prior art and can be designed to be smaller in size.

[0033] In the embodiment of this application, by integrating the NFC induction module 300 in the first electrode sheet 100 and the second electrode sheet 200, the attachment position of the first electrode sheet 100 and / or the second electrode sheet 200 on the human body model can be realized by using the NFC induction module 300. At the same time, since the NFC induction module 300 is based on NFC technology, its structure is simple and the size can be designed to be smaller. Therefore, the thickness of the first electrode sheet 100 and the second electrode sheet 200 provided in this application is smaller, so the fitting degree on the human body model is high, and it is not easy to generate the problem of warping, ensuring the stability and reliability of pasting. In addition, in the electrode sheet assembly of the defibrillation training device provided in this application, the first electrode sheet 100 and the second electrode sheet 200 use the NFC induction module 300 to realize communication with the NFC tag on the human body model. Therefore, the electrode sheet assembly of the defibrillation training device also has the advantages of high communication stability, fast communication speed, strong data security, low power consumption, and low cost.

[0034] Please refer to Figure 1 , a spiral coil disk is arranged in the middle of the electrode sheet in the prior art. In the non-attached state, the coil disk is flat and the electrode sheet as a whole is also flat. Since there is a certain curvature on the surface of the human body model, when the electrode sheet is attached to the surface of the human body model, the electrode sheet and the coil disk will undergo a certain deformation to fit the curvature of the surface of the human body model. However, as Figure 1The size of the internal coil disk of the electrode patch shown is large and the elasticity is small, so the coil disk may tend to return to a flat state. The restoring force of an elastic object after deformation due to an external force is simply referred to as elastic force. Under the action of the elastic force of the coil disk and the elastic force of the electrode patch body, when the overall elastic force of the electrode patch is greater than the viscosity of the electrode patch surface, the electrode patch will return to a flat state, and thus the edge of the electrode patch will gradually separate from the mannequin, resulting in the problem of the electrode patch warping. It can be seen that the larger the size and the higher the hardness of the internal coil disk of the electrode patch, the more likely the electrode patch is to warp.

[0035] In one embodiment, the NFC sensing module 300 may include an antenna 310. As Figure 2 shown, the antenna 310 may form a coil structure with a hollow interior. The NFC sensing module 300 may use the antenna 310 to transmit and receive a wireless electromagnetic field, and data exchange and transmission may be achieved between the antenna 310 and the NFC tag on the mannequin based on magnetic field coupling. The antenna 310 can receive wireless energy from the NFC tag on the mannequin through non-radiative electromagnetic induction. When interacting with the NFC tag in the passive communication mode, the energy received by the antenna 310 can activate the circuit on the NFC tag, enabling it to transmit the stored information. When the antenna 310 approaches the NFC tag on the mannequin, the antenna 310 captures the surrounding electromagnetic signals and converts them into electrical signals for further processing by the defibrillation training device. Similarly, the antenna 310 can also convert the electrical signals processed by the defibrillation training device back into electromagnetic signals and send them to other NFC devices.

[0036] Compared with the relatively large-sized spiral coil disk provided in the existing electrode patch as Figure 1 shown, the antenna 310 used in the first electrode patch 100 and the second electrode patch 200 provided in this application forms a coil structure with a hollow interior. The hollow part in the middle of the coil structure does not deform and does not generate elastic force. Therefore, when the first electrode patch 100 and the second electrode patch 200 are attached to the surface of the mannequin, the elastic force caused by the overall deformation is smaller. It can be seen that by designing the antenna 310 as a coil structure with a hollow interior, the electrode patch assembly provided in this application can reduce the deformation of the antenna 310 when the first electrode patch 100 and the second electrode patch 200 are attached to the surface of the mannequin. Furthermore, the first electrode patch 100 and the second electrode patch 200 have a higher degree of fit with the mannequin, are not prone to warping and falling off, and can better adhere to the mannequin.

[0037] In one embodiment, the shape of the coil structure of the antenna 310 may include but is not limited to circular, oval, fan-shaped, triangular, polygonal. Figure 2Shown is a schematic diagram of the antenna 310 forming a rectangular coil structure. As long as the coil formed by the antenna 310 in the electrode sheet assembly of the present application has a hollow structure inside, the shape of the coil structure of the antenna 310 may not be limited to the above shape. For example, Figure 3 is a schematic diagram of the coil structure of the antenna in one embodiment of the present application. The coil structure of the antenna 310 may also be, for example, Figure 3 the unclosed and irregular hollowed-out pattern shown.

[0038] Figure 4 Shown is a schematic diagram of the structure of the NFC induction module in one embodiment of the present application. In one embodiment, the NFC induction module may further include a flexible circuit board 320, a first conductive sheet 330, and a second conductive sheet 340. The antenna 310, the first conductive sheet 330, and the second conductive sheet 340 may all be formed on the surface of the flexible circuit board 320. Among them, the first end of the antenna 310 may be connected to the first conductive sheet 330, and the second end of the antenna 320 may be connected to the second conductive sheet 340.

[0039] A flexible printed circuit (FPC) is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the base material, with the characteristics of high wiring density, light weight, thin thickness, and good bendability. The thickness range of the flexible circuit board is usually between 0.1 mm and 0.5 mm. Circuit designs can be embedded on the flexible circuit board to stack a large number of precision components in a narrow and limited space, thereby forming a flexible circuit that can be bent.

[0040] In the electrode sheet assembly of the defibrillation training device provided by the present application, the NFC induction circuit formed by the antenna 310, the first conductive sheet 330, and the second conductive sheet 340 may be integrated on the flexible circuit board 320. As shown in Figure 4 the figure, the antenna 310 forms a hollow coil structure inside on the surface of the flexible circuit board 320. The position of the flexible circuit board 320 corresponding to the hollow area inside the coil structure may also be hollowed out, that is, the flexible circuit board 320 may also be a hollow structure inside. The part of the flexible circuit board 320 provided with the antenna 310 is adapted to the shape and size of the antenna 310. By designing the flexible circuit board 320 to be a hollow structure inside, the deformation generated by the flexible circuit board 320 can be reduced.

[0041] Since the flexible circuit board 320 has the advantages of thin thickness and good bendability, and at the same time, a smaller and more precise antenna 310 structure can be formed on the flexible circuit board 320, the size of the NFC induction module 300 can be further reduced, the thickness of the first electrode sheet 100 and the second electrode sheet 200 can be reduced, and the elastic force caused by the deformation of the first electrode sheet 100 and the second electrode sheet 200 can be reduced. Compared with, for example,Figure 1 The spiral antenna disk electrode sheet inside the shown electrode sheet. When the antenna 310 in the first electrode sheet 100 and the second electrode sheet 200 provided in this application is integrated on the flexible circuit board 320, not only can the size of the antenna 310 be reduced, making the first electrode sheet 100 and the second electrode sheet 200 thinner, easier to manufacture, and simpler to assemble, but also the wiring of the antenna 310 can be reduced and the cost can be saved. At the same time, the overall hardness of the NFC induction module 300 is also lower.

[0042] In one embodiment, the NFC induction module 300 may further include a reinforcing plate 350. The reinforcing plate 350 may be disposed in the area of the flexible circuit board 320 corresponding to the first conductive sheet 330 and the second conductive sheet 340. Please refer to Figure 4 , the area of the flexible circuit board 320 corresponding to the first conductive sheet 330 and the second conductive sheet 340 may be defined as a reinforcing area 321. The antenna 310, the first conductive sheet 330, and the second conductive sheet 340 may be formed on the first surface of the flexible circuit board 320, and the flexible circuit board 320 may further include a second surface opposite to the first surface.

[0043] Figure 5 It is a schematic structural diagram of a reinforcing plate disposed on a flexible circuit board in one embodiment of this application. The reinforcing plate 350 may be disposed in the reinforcing area 321 on the second surface of the flexible circuit board 320. The reinforcing area 321 corresponding to the first conductive sheet 330 and the second conductive sheet 340 on the flexible circuit board 320 bears a relatively large force and is prone to bending. Since the flexible circuit board 320 has a high degree of flexibility, there may be a problem that its strength is insufficient to support the loaded devices or withstand the mechanical stress during the operation process.

[0044] By disposing the reinforcing plate 350 in the reinforcing area 321, the hardness and anti-bending ability of the reinforcing area 321 can be increased, preventing the NFC induction circuit on the flexible circuit board 320 from being damaged during installation, handling, or use. In addition, the NFC induction module 300 can be connected to external devices through the first conductive sheet 330 and the second conductive sheet 340. The reinforcing plate 350 can help maintain the shape and position of the reinforcing area 321, especially in places where it needs to cooperate with hard components (such as connection terminals, connection fixed points), ensuring accurate alignment and stable connection between the first conductive sheet 330 and the second conductive sheet 340 and external devices.

[0045] Meanwhile, since adding the reinforcement plate 350 may increase the thickness and hardness of the first electrode sheet 100 and the second electrode sheet 200, the shape of the reinforcement plate 350 can be designed to match the shape of the regions where the first conductive sheet 330 and the second conductive sheet 340 are arranged, so as to reduce the influence of the reinforcement plate 350 on the thickness and hardness of the first electrode sheet 100 and the second electrode sheet 200, and ensure the fitting degree of the first electrode sheet 100 and the second electrode sheet 200 with the surface of the simulated human body.

[0046] Figure 6 FIG. 4 is a schematic connection diagram of the first conductive sheet and the second conductive sheet to the connection terminals of the external cable in one embodiment of the present application. In one embodiment, the NFC induction module 300 can be connected to the connection terminals of the external cable 10 through the first conductive sheet 330 and the second conductive sheet 340. Figure 6 The shown first conductive sheet 330 and second conductive sheet 340 are circular copper rings. In some other embodiments, the first conductive sheet 330 and the second conductive sheet 340 can also be conductive sheets of other shapes or other conductive materials. The NFC induction module 300 can be connected to the connection terminals 11 of the external cable 10 through the first conductive sheet 330 and the second conductive sheet 340. The external cable 10 can include two connection terminals 11, and the two connection terminals 11 can be respectively fixed on the first conductive sheet 330 and the second conductive sheet 340. The other end of the external cable 10 is detachably connected to the main body of the defibrillation training device, so that the signals or data acquired by the NFC induction module 300 in the first electrode sheet 100 and the second electrode sheet 200 can be transmitted to the main body of the defibrillation training device, and the main body of the defibrillation training device can further process the signals or data acquired by the NFC induction module 300.

[0047] Figure 7 FIG. 10 is a schematic structural diagram of a partial cross-section of the body of the first electrode sheet or the second electrode sheet in one embodiment of the present application. In one embodiment, the bodies of the first electrode sheet 100 and the second electrode sheet 200 can both include an insulating base layer 110 and an insulating adhesive layer 120, and the insulating base layer 110 and the insulating adhesive layer 120 can be arranged in a laminated manner. The NFC induction module 300 can be arranged between the insulating base layer 110 and the insulating adhesive layer 120. The insulating base layer 110 and the insulating adhesive layer 120 can completely cover the NFC induction module 300. The insulating base layer 110 can be prepared from an insulating material, and the insulating adhesive layer 120 can be prepared from an insulating and adhesive material. The insulating base layer 110 and the insulating adhesive layer 120 can provide support and protection for the NFC induction module 300, and at the same time can also prevent the signals transmitted on the NFC induction module 300 from leaking and ensure the safe use of the first electrode sheet 100 and the second electrode sheet 200.

[0048] The insulating adhesive layer 120 enables the first electrode sheet 100 and the second electrode sheet 200 to adhere to the skin of a patient. Since the electrode sheet assembly provided in this application is for a simulation device for defibrillation training, when the electrode sheet assembly is attached to a simulated human, it is necessary to ensure not only that the electrode sheet can adhere to the surface of the simulated human, but also that the electrode sheet is easy to tear off. Therefore, the adhesiveness of the insulating adhesive layer 120 should not be too high. That is, the adhesiveness of the insulating adhesive layer 120 is moderate, and the adhesiveness of the insulating adhesive layer 120 is greater than the elasticity caused by the deformation of the first electrode sheet 100 and the second electrode sheet 200.

[0049] Figure 8 FIG. 4 is a schematic diagram of the first electrode sheet and the second electrode sheet in one embodiment of the present application. Among them, FIG. 8a is a schematic diagram of the structure of the first surface of the first electrode sheet or the second electrode sheet in one embodiment of the present application, and FIG. 8b is a schematic diagram of the structure of the second surface of the first electrode sheet or the second electrode sheet in one embodiment of the present application. In one embodiment, the first electrode sheet 100 and the second electrode sheet 200 may further include a protective layer 130. The protective layer 130 may be disposed on the outer surfaces of the first electrode sheet 100 and the second electrode sheet 200, and the protective layer 130 may be disposed on both opposite surfaces of the first electrode sheet 100 and the second electrode sheet 200. The fixed position of the protective layer 130 may correspond to the connection area between the NFC induction module 300 and the external cable 10, and the shape of the protective layer 130 may match the shape of the connection area.

[0050] The NFC induction module 300 may be connected to the two connection terminals 11 of the external cable 10 through the first conductive sheet 330 and the second conductive sheet 340 respectively. Similarly, when the first electrode sheet 100 and the second electrode sheet 200 are actually used, the connection area between the NFC induction module 300 and the external cable 10 bears a large force and is prone to bending, thereby causing damage to the external cable 10. By providing the protective layer 130 on the outer surfaces of the first electrode sheet 100 and the second electrode sheet 200 at the connection area between the NFC induction module 300 and the external cable 10, damage to the first conductive sheet 330, the second conductive sheet 340, and the external cable 10 during installation and use can be prevented. At the same time, since adding the protective layer 130 may increase the thickness and hardness of the first electrode sheet 100 and the second electrode sheet 200, by designing the shape of the protective layer 130 to match the shape of the connection area, the influence of the protective layer 130 on the thickness and hardness of the first electrode sheet 100 and the second electrode sheet 200 can be reduced, ensuring the fit of the first electrode sheet 100 and the second electrode sheet 200 to the surface of the simulated human, ensuring that the first electrode sheet 100 and the second electrode sheet 200 are not prone to warping problems, and improving the stability and reliability of adhesion during use.

[0051] In one embodiment, the hardness of the protective layer 130 can be greater than the hardness of the insulating base layer 110 and / or the hardness of the insulating adhesive layer 120. By designing the hardness of the protective layer 130 to be greater than the hardness of the insulating base layer 110 and / or the hardness of the insulating adhesive layer 120, the protection of the NFC induction module 300 and the external cable 10 can be strengthened, preventing damage to the first conductive sheet 330, the second conductive sheet 340, and the external cable 10.

Each embodiment focuses on the differences from other embodiments.
