Description

TECHNICAL FIELD

[0001] The present application relates to a defibrillation electrode patch with compression frequency detection, humidity detection and sterilization function, and also relates to an automatic external defibrillator and a corresponding defibrillator system using the defibrillation electrode patch, belonging to the technical field of medical devices. BACKGROUND

[0002] With the popularization of automatic external defibrillators (AEDs), many public places are equipped with automatic external defibrillators. When someone faints or needs first aid, ordinary people can also use AEDs to perform first aid measures on the person. In the first aid process, defibrillation equipment is used for defibrillation, and then cardiopulmonary resuscitation (CPR) is performed to restore the heartbeat of the person being rescued.

[0003] In the corresponding first aid, standard cardiopulmonary resuscitation operations are of great significance to saving lives. The 2020 edition of the American Heart Association's Guidelines for Cardiopulmonary Resuscitation states that the standard for cardiopulmonary resuscitation requires a compression frequency of 100-120 times per minute. There are also specifications for compression depth, the ratio of external chest compression to artificial respiration, etc. Using standardized or effective first aid measures can improve first aid efficiency.

[0004] However, defibrillation equipment is installed in public places and is intended for public use. People who actually use defibrillation equipment for first aid measures may not have received professional first aid training. For people who have not received professional first aid training, it is often difficult to master the compression frequency and ensure effective first aid.

[0005] Since the existing conventional defibrillation electrode patch only contains two defibrillation electrode patches and cannot detect the compression frequency, the two electrode patches are respectively pasted on the left and right sides of the chest of the human body and cannot cover the compression site of cardiopulmonary resuscitation. However, during cardiopulmonary resuscitation compression, the chest of the human body will float up and down with the compression action, and the compression action can be detected by detecting the up and down floating of the chest. To obtain the compression frequency, a feasible technical concept is to set a compression frequency detection function on the existing defibrillation electrode patch. In the case of using a defibrillator, the defibrillation electrode patch is used to detect the compression frequency during cardiopulmonary resuscitation, prompting or guiding the first aid personnel to perform first aid.

[0006] In addition, the general validity period of the existing defibrillation electrode patch is 5 years, and the defibrillation electrode patch may not be used within the validity period after being placed in a fixed location. Thus, the defibrillation electrode patch that exceeds the validity period will be scrapped, causing waste of materials.

[0007] The defibrillation electrode sheet realizes the transmission of the electrocardiosignal and the defibrillation energy through the conductivity of the conductive gel. When the humidity of the conductive gel decreases, the impedance between the human skin and the electrode increases, which leads to the decrease of the conductivity, and affects the signal detection and the defibrillation effect. Therefore, the humidity of the conductive gel of the defibrillation electrode sheet can effectively reflect the effectiveness of the defibrillation electrode sheet.

[0008] The defibrillation electrode sheet is installed together with the defibrillation device in different environments. The defibrillation electrode sheet needs to ensure effectiveness at any time of use. However, the effectiveness of the defibrillation electrode sheet within the effective period cannot be monitored in real time.

[0009] The installation of the defibrillation device is widely distributed and scattered. The cost of detecting and maintaining the defibrillation electrode sheet by manual work is high, and the detection period is long. Moreover, the effectiveness of the defibrillation electrode sheet produced and not installed for use cannot be effectively detected.

[0010] During defibrillation, the automatic external defibrillator provides defibrillation energy to the defibrillation electrode sheet. When the impedance of the conductive gel of the defibrillation electrode sheet does not meet the requirements, the defibrillation voltage will be too large to cause safety problems. Therefore, the impedance of the conductive gel of the defibrillation electrode sheet is measured to ensure the safe and effective use of the defibrillation electrode sheet. SUMMARY

[0011] The multifunctional defibrillation electrode sheet is provided based on the above technical concept. The automatic external defibrillator and the defibrillator system based on the defibrillation electrode sheet are also provided. The first aid personnel can use the defibrillator to know the compression frequency implemented in the cardiopulmonary resuscitation during the first aid process, so as to effectively perform first aid.

[0012] The technical scheme of the present application is as follows: the multifunctional defibrillation electrode sheet is provided with two electrode sheets (or sheet bodies), which are a left electrode sheet and a right electrode sheet. At least one electrode sheet (usually the right electrode sheet) is provided with a compression detection module. The compression detection module includes an acceleration sensor and an acceleration sensor control and wireless transmission module. The sensing output of the acceleration sensor is connected to the acceleration sensor control and wireless transmission module. The acceleration sensor control and wireless transmission module is provided with an upper connection line for connecting with an upper device (including a network). The upper connection line of the acceleration sensor control and wireless transmission module is connected to a compression detection module connection end (connector, for example, a multi-pin plug). When the electrode sheet connection end is set, the electrode sheet connection end can be used as the impedance detection module connection end, and the upper connection line of the acceleration sensor control and wireless transmission module is connected to the electrode sheet connection end.

[0013] The electrode sheet connection end (or electrode sheet connector, for example, a multi-pin plug) uses the electrode sheet connection end as a wired connector for realizing the upper connection (connection with the upper device).

[0014] The electrode sheet can adopt any suitable prior art, and can generally be provided with a common layer and a defibrillation layer, the common layer being a layer of non-conductive material constituting the base of the electrode sheet, and the defibrillation layer being provided with a layer of conductive material (or electrode) for conducting electric pulses to implement shock therapy, the defibrillation layer being located below the common layer and attached to the back (lower surface) of the common layer, forming an integrated sheet structure with the common layer.

[0015] The common layer can adopt a double-layer structure, including a first common layer and a second common layer, the second common layer being located below the first common layer and attached to the back (lower surface) of the first common layer, and the defibrillation layer being located below the second common layer and attached to the back of the second common layer, the first common layer, the second common layer and the defibrillation layer being sequentially attached and fixedly connected to form an integrated sheet structure.

[0016] According to actual conditions, any suitable connection mode such as adhesive bonding, adhesive-free bonding (e.g. heat sealing) can be adopted to realize the connection between the surfaces of the layers.

[0017] Preferably, the defibrillation layer can be composed of a defibrillation layer base material layer and a conductive material layer, the conductive material layer being arranged on the back of the defibrillation layer base material layer.

[0018] The conductive material layer preferably adopts a textile electrode.

[0019] The back of the conductive material layer can be provided with a conductive gel layer.

[0020] The conductive material layer preferably does not cover the entire back of the defibrillation layer base material layer, that is, the edge region of the back of the defibrillation layer base material layer is not covered by the conductive material layer.

[0021] The specific shape and size of the conductive material layer can be based on prior art.

[0022] The outer surface (lower surface) of the conductive gel layer can be covered with non-stick adhesive paper for protection, which can be removed before use.

[0023] The conductive gel of the electrode sheet contains Ag + , which can be realized by adding a suitable Ag + -containing substance (or agent, or Ag + -containing raw material) to the conductive gel, has sustained antibacterial function, and is conducive to reducing the allergic reaction of human skin to the defibrillation electrode sheet.

[0024] The pressing detection module is preferably installed on the right electrode sheet, in particular, on the common layer of the right electrode sheet, and is not connected to the conductive material layer of the right electrode sheet.

[0025] Generally, the acceleration sensor is preferably arranged at the near-pressing area of the right electrode pad (when in use, that is, when the right electrode pad is attached to the human body part where the defibrillation should be performed, the area of the right electrode pad near the cardiopulmonary resuscitation pressing part), so as to more effectively obtain the pressing signal.

[0026] The acceleration sensor can adopt any suitable form. For example, a three-axis gyroscope, which can be selected according to the movement characteristics of the electrode pad in first aid and the arrangement space on the electrode pad.

[0027] Some commercially available acceleration sensors can be integrated with corresponding acceleration sensor control and wireless transmission modules, which can be used as the pressing detection module.

[0028] The acceleration sensor control / signal acquisition circuit in the acceleration sensor control and wireless transmission module can be arranged according to the characteristics of the acceleration sensor.

[0029] The acceleration sensor control and wireless transmission module has wireless communication function, and can perform wireless communication with the defibrillation device (defibrillator host) to transmit the pressing frequency detection signal.

[0030] The acceleration sensor control and wireless transmission module can also be connected with the defibrillation device through corresponding upper connection lines and electrode pad connection terminals.

[0031] The upper connection lines of the acceleration sensor control and wireless transmission module can be connected to the corresponding connection points (pins, pins, connection pieces, etc.) on the electrode pad connection terminals, so that the electrode pad connection terminals serve as the unified wired interface of the pressing detection module and other modules / elements on the electrode pad.

[0032] When the general layer adopts a double-layer structure, a groove-type cavity (groove-type space, slot sealing or not sealing) for mounting the pressing detection module can be arranged on the front surface (upper surface) of the second general layer, or groove-type cavities for mounting the acceleration sensor and the acceleration sensor control and wireless transmission module, respectively, can be arranged, and corresponding threading grooves / wiring grooves can be arranged on the front surface or inside of the second general layer to arrange the connection lines for connecting the sensing signal of the acceleration sensor to the acceleration sensor control and wireless transmission module.

[0033] Preferably, an impedance detection module for detecting the impedance of the conductive gel layer is arranged.

[0034] For example, the impedance detection module includes an impedance detection module for unified detection of two electrode pads, impedance detection points of which are arranged on the left electrode pad and the right electrode pad respectively, for obtaining impedance of the conductive gel layer of the two electrode pads, and impedance of the conductive gel layer of a single electrode pad (average value) can be obtained based on impedance of the conductive gel layer of the two electrode pads; and / or, the impedance detection module includes impedance detection modules for detection of a single electrode pad, the number of which is two, impedance detection points of the impedance detection modules are arranged on the respective electrode pads, for respectively obtaining impedance of the conductive gel layer of the corresponding electrode pad.

[0035] The impedance detection module includes an impedance detection module connection end (or an impedance detection module connector, for example, a plug and socket plug-in connector / assembly), and detection connection lines of the impedance detection points are connected to the impedance detection module connection end (connector or hub, for example, a multi-pin plug).

[0036] The inner side (electrode pad side) of the impedance detection module connection end is connected to the respective impedance detection points through the corresponding detection connection lines, and when the electrode pad connection end is arranged, the outer side of the impedance detection module connection end is connected to the electrode pad connection end through the upper connection lines of the impedance detection module, and the corresponding upper connection lines thereof can be connected to the corresponding connection points on the electrode pad connection end, and the electrode pad connection end is used as a wired connector for upper connection of the impedance detection module.

[0037] For example, the impedance detection points of the impedance detection module for unified detection of two electrode pads can be alternating current impedance detection points, the number of which is two, arranged on the conductive material layer of the left electrode pad and the conductive material layer of the right electrode pad respectively, the left electrode pad and the right electrode pad are fixed (both relatively fixed) and stacked together, the defibrillation layers of the two electrode pads are opposite to each other, and the two alternating current impedance detection points can also be in corresponding positions. By connecting alternating current for detection between the two alternating current impedance detection points through the corresponding detection connection lines, the capacitance of the capacitor composed of the two electrode pads can be calculated based on the voltage and current data, and based on the conductive material layer of the defibrillation layer and its distribution, the impedance of the conductive gel layer to be obtained can be calculated from the detected capacitance by using the existing technology.

[0038] For example, the impedance detection points of the impedance detection module for detecting the single electrode sheet can be DC impedance detection points, and the number of the DC impedance detection points on the same electrode sheet is two, which are a first DC impedance detection point and a second DC impedance detection point. The first DC impedance detection point is preferably located at one side edge of the conductive gel layer of the corresponding electrode sheet, and the second DC impedance detection point is preferably located at the other side edge of the conductive material layer of the corresponding electrode sheet and has a spacing from the conductive gel layer to avoid direct electrical contact between the detection connecting line and the conductive gel layer. By connecting a DC voltage between the two DC impedance detection points on the same electrode sheet through the corresponding detection connecting line, the resistance of the combination of the conductive material layer and the conductive gel layer can be calculated based on the voltage and current data.

[0039] In the case of detecting the voltage between the two points on each electrode sheet, the relative position of the two electrode sheets does not need to be limited.

[0040] Generally, the two DC impedance detection points should be arranged in the direction in which the defibrillation layer substrate material layer and the conductive gel layer have the largest or sufficient span to improve the detection accuracy.

[0041] According to the specific distribution of the two DC impedance detection points and the specific conditions of the defibrillation layer conductive material layer and the conductive gel layer, the impedance of the conductive gel layer to be obtained can be derived based on the prior art from the detected voltage-related information.

[0042] Preferably, at least one electrode sheet is provided with a humidity detection module for detecting the humidity of the ambient air (the humidity of the air in the electrode sheet packaging bag).

[0043] The humidity detection module includes a humidity sensor and a humidity sensor control and wireless transmission module. The sensing output of the humidity sensor is connected to the humidity sensor control and wireless transmission module. The humidity sensor control and wireless transmission module is provided with an upper connection line for connecting to an upper device (including a network). The upper connection line of the humidity sensor control and wireless transmission module is connected to the humidity detection module connection end (connector, for example, a multi-pin plug). When the electrode sheet connection end is arranged, the electrode sheet connection end can be used as the humidity detection module connection end. The upper connection line of the humidity sensor control and wireless transmission module is connected to the electrode sheet connection end, and the electrode sheet connection end is used as the wired connector for realizing the upper connection (connection with the upper device).

[0044] A groove-shaped cavity for mounting the humidity detection module or groove-shaped cavities for mounting the humidity sensor and the humidity sensor control and wireless transmission module respectively can be arranged on the front surface of the common layer, when the common layer adopts a double-layer structure, the groove-shaped cavity(s) is / are arranged on the front surface (upper surface) of the second common layer, the top of the groove-shaped cavity for mounting the humidity sensor is open or is provided with a through hole communicating with the external space, so that external air (humidity) can enter and the humidity sensor can obtain real-time humidity information.

[0050] When other modules are provided, any module can use the electrode patch connection end as the wired connector for realizing the upper connection, in which case the upper connection line of the corresponding module is connected to the electrode patch connection end.

[0051] According to actual needs, multiple electrode patch connection ends can be provided, which are respectively used for connection in different cases or are respectively used for connection of different modules.

[0060] Generally, the defibrillation electrode pad, the defibrillation device, the external impedance detection device, and the external wireless device are arranged on site, and can be arranged on site according to the site conditions.

[0061] A box body can be arranged, and the packaged defibrillation electrode pads are placed in the box body, and two electrode pads are located in the sealed electrode pad packaging bags.

[0062] Preferably, in the state that the defibrillation electrode patch is not connected to the defibrillation device and the state that the defibrillation electrode patch is connected to the defibrillation device, the impedance of the conductive gel is detected, and when the impedance of the conductive gel meets the corresponding alarm condition or does not meet the corresponding non-alarm condition, the on-site and / or remote prompt or alarm related to the impedance of the conductive gel is performed.

[0063] For example, in the state that the defibrillation electrode patch is not connected to the defibrillation device, the external impedance detection device can connect the detection power supply of the impedance detection module through the impedance detection module connection end and the corresponding connection line according to the set rules / programs (for example, periodically), or according to manual input, or according to remote control instructions, start impedance detection, collect corresponding detection data and perform impedance operation, and obtain the measured impedance data of the corresponding electrode patch. Further, comparison can be made with the impedance range standard, and when the measured impedance data is not within the impedance range standard, local result display and sound / speech alarm can be performed, and detection data can be transmitted to a remote monitoring platform using remote communication technology and communication network, and the detection data can also be stored locally.

[0064] For example, when the electrode patch connection end is connected to the defibrillation device defibrillator connection end, the defibrillation device obtains electrode patch connection information, connects the detection power supply of the impedance detection module through the defibrillator connection end, the electrode patch connection end, the impedance detection module connection end and the corresponding connection line, starts impedance detection, collects corresponding detection data and performs impedance operation to obtain the measured impedance data of the corresponding electrode patch.

The double-layer structure of the ordinary layer helps the arrangement of the related modules on the electrode pad.

The connecting lines are arranged according to the actual needs of each module, for example, the specific sensors selected and the specific wireless transmission modules / circuits selected, which can be used to transmit sensing signals, control signals, and as a power line for detection to apply voltage or current between detection points or detection points. From the connection direction, it can include the upper connecting line 38 of the humidity detection module 31, the upper connecting line 28 of the pressing detection module, the upper connecting line 48 of the impedance detection module, and the connecting line (which can be regarded as the upper connecting line of the acceleration sensor) 26 between the sensing output end of the acceleration sensor 21 and the corresponding sensing signal input end of the acceleration sensor control and wireless transmission module 22, and the detection connecting line 46 between the impedance detection point 41 (direct current impedance detection point or alternating current impedance detection point) and the corresponding connecting end of the impedance detection module connecting end 42. The upper connecting line refers to the connecting line between the upper device (including the network, the connecting end, etc.). The upper connecting line of the same module can be one or more, and the multiple upper connecting lines can be used for different purposes.

[0085] The connection lines include multiple independent signal connection lines for transmitting signals between each module and the defibrillation device (e.g., detection signals / sensing signals, detection instructions, etc.), and multiple detection connection lines (power supply lines applied to corresponding detection points), etc. For any connection line, from the perspective of the connected lower module / element, it can be regarded as an upper connection line for realizing upper connection.

[0086] The defibrillation electrode patch is provided with a humidity detection module, an impedance detection module, an electrocardio detection module, a defibrillation module, and a compression frequency detection module. The compression frequency detection module is installed on the right electrode patch. The humidity detection module can be installed on any electrode patch or both electrode patches. The electrocardio detection module and the defibrillation module are already available in existing defibrillation electrode patches, and existing technologies can be used.

[0087] Before use, the left electrode patch and the right electrode patch are sealed together in an electrode patch packaging bag (referred to as a packaging bag). The packaging bag has a connection line outlet through which the upper connection lines of each module can pass and be connected to the impedance detection module connection end or the electrode patch connection end outside the packaging bag. The connection line outlet is sealed with glue except for the space of the connection line outlet, so as to maintain the sealing state of the packaging bag.

[0088] The impedance detection module connection end can be a concentrator or a plug-in connector. The electrode patch side connection lines are respectively connected to the corresponding impedance connection points of the left electrode patch and the right electrode patch, and the defibrillator side connection lines are connected to the electrode patch connection end.

[0089] The left electrode patch and the right electrode patch can have a multi-layer structure. The multi-layer structure includes a defibrillation layer and a general layer on which the humidity detection module and the compression frequency detection module are placed. The humidity detection module and the compression frequency detection module can be fixed by adding a fixed cavity to the general layer or by using two layers of general layers.

[0090] The connection lines include signal connection lines for transmitting electrocardio signals, defibrillation energy, current signals for impedance detection, humidity signals, impedance signals, compression frequency signals, instruction signals for detecting humidity, and power supply signals for each module.

[0091] One side of the electrode patch connection end is respectively connected to the corresponding modules of the two electrode patches through connection lines, and the other side is connected to the defibrillation device to transmit signals to the defibrillation device.

[0092] The fixing methods of the humidity detection module and the compression frequency detection module can be as follows:

[0093] The left and right electrode pads can each have a fixing cavity on the front surface of the first common layer, in which a humidity detection module is placed, and a small hole is left on the side of the fixing cavity close to the outlet of the connecting line of the packaging bag, through which the signal connecting line passes, thereby fixing the signal connecting line; the front surface of the second common layer has a fixing cavity in which a pressing frequency detection module is placed, and a small hole is left on the side of the fixing cavity close to the connecting line of the outlet of the connecting line of the sealing bag, through which the signal connecting line passes, thereby fixing the signal connecting line.

[0094] The fixing cavity for placing the pressing frequency detection module can be one, in which the acceleration sensor and its wireless control and transmission module are placed together; or two fixing cavities, in which the acceleration sensor and its wireless control and transmission module are placed separately.

[0095] The fixing cavities for fixing the pressing frequency detection module and the humidity detection module can also be in the same common layer.

[0096] The humidity detection module of the left and right electrode pads can be fixed by being sandwiched between two common layers, and the signal connecting line is led out to the electrode pad connecting end between the two common layers.

[0097] The bottom layer of the left and right electrode pads is a defibrillation layer, and the base material of the defibrillation layer is a common textile material for electrode pads. The defibrillation layer is provided with a layer of conductive material, which can be a metal foil or a textile electrode, and the metal foil or the textile electrode is attached to the base material of the defibrillation layer.

[0098] When the layer of conductive material on the defibrillation layer is a textile electrode, a layer of conductive gel is covered on the surface (lower surface) of the textile electrode that is not connected to the base material, and then a layer of non-stick adhesive paper is covered on the conductive gel to protect the conductive gel.

[0099] The textile electrode does not cover the back surface of the defibrillation layer completely, and a non-covered area is left around the periphery.

[0100] The defibrillation layer is provided with an impedance detection module, which has the following two schemes:

[0101] The first mode is to use an alternating current signal to realize impedance detection, which is suitable for the case that the defibrillation layers of the left and right electrode pads are placed opposite to each other. When the defibrillation layers of the left and right electrode pads are placed opposite to each other, the metal foil or textile electrode on the defibrillation layers of the left and right electrode pads is not conductive, so that the defibrillation layers of the left and right electrode pads form a capacitor. Two detection connection lines of the impedance detection module are respectively fixedly connected to impedance detection points (in this case, they can also be referred to as alternating current impedance detection points) on the electrode pads. An alternating current signal is transmitted to the metal foil or textile electrode on the defibrillation layers of the left and right electrode pads through the corresponding connection lines. The impedance of the defibrillation layer can be measured by the alternating current impedance detection method in the prior art. If necessary, the detection points can be connected to the defibrillation device or external impedance detection device through the upper connection line of the impedance detection module. The defibrillation device can perform impedance detection and various data processing required by the existing impedance detection technology according to the applied and detected alternating current voltage to calculate the impedance.

[0102] The specific implementation can be that the external impedance detection device or the defibrillation device provides an alternating current signal to the impedance detection module connection end. The alternating current signal is transmitted to the conductive sheet (a conductive body provided on the detection point for connecting the connection line) on the metal foil or textile electrode of the defibrillation layer of the right electrode pad through the right impedance detection signal line. The alternating current signal is transmitted to the metal foil or textile electrode of the defibrillation layer of the left electrode pad through the capacitor environment formed by the metal foil or textile electrode and the conductive gel of the left and right electrode pads, and then transmitted to the left impedance detection signal line through the conductive sheet on the metal foil or textile electrode. The left impedance detection signal line transmits the signal to the impedance detection connection end, and then transmits the signal to the defibrillation device or external impedance detection device. The defibrillation device or external impedance detection device analyzes and calculates the impedance value of the conductive gel of the defibrillation electrode pad.

[0103] The second mode is to use a direct current signal to realize impedance detection. Two direct current impedance detection points are arranged on the same electrode pad, one on the conductive material layer and one on the conductive gel layer. There is enough space between the two detection points. Two detection connection lines are connected to the two detection points, and the detection connection lines are connected to the signal output end of the defibrillation device or external impedance detection device through the detection module connection end. A direct current is applied through the two detection connection lines. The defibrillation device or external impedance detection device calculates the corresponding impedance according to the applied current and voltage information.

[0104] A preferred embodiment is to set up a separate detection area on the defibrillation layer, on the defibrillation layer base material layer of the separate detection area, from top to bottom, a detection conductive material layer 141 and a detection conductive gel layer 151 are arranged in turn, the materials and layer thicknesses of the detection conductive material layer and the detection conductive gel layer are the same as those of the conductive material layer 14 and the conductive gel layer 5, one direct current detection point 411 is arranged on the detection conductive gel, and the other direct current detection point 412 is arranged on the detection conductive material layer, the detection connecting wires 461 and 462 are respectively connected to the two direct current detection points, direct current is applied through the defibrillation device or external impedance detection device, impedance detection is carried out according to the same principle and mode, and the performance and condition of the conductive gel can be inferred according to the performance and condition of the detection conductive gel, because the detection conductive gel has the same material as the conventional (defibrillation) conductive gel of the electrode sheet and is stored in the same storage condition and storage environment.

[0105] In the above impedance detection mode, the impedance detection module (detection point and detection connecting wire) is separated from the conductive gel used for defibrillation and detection of electrocardio signals, and there is no electrical connection between them to avoid mutual interference.

[0106] The impedance detection signal line (or detection connecting wire, or detection power supply line, or signal connecting wire) can pass through the base material layer of the defibrillation layer at the position of the measurement point (detection point), and be led out from the front surface of the defibrillation layer, thereby also playing a fixing role for the conductive sheet on the detection point for connecting the detection connecting wire.

[0107] A signal line passage cavity (wiring passage) can be arranged on the front surface of the defibrillation layer base material layer, for placing and fixing the two signal connecting wires of the impedance detection module.

[0108] The defibrillation device detects whether the defibrillation electrode sheet is installed on the defibrillation device through the detection interface level signal, and when the defibrillation electrode sheet is installed on the defibrillation device, the electrode sheet connecting end is connected to the corresponding interface (for example, inserted into the corresponding socket / slot on the defibrillation device) of the defibrillation device, and the defibrillation device judges through the level signal of the interface. If it is detected that the defibrillation electrode sheet has been successfully installed, the defibrillation device provides power supply and related start signals for the defibrillation electrode sheet; if the defibrillation device detects that the defibrillation electrode sheet has not been successfully installed on the defibrillation device, an alarm signal will be sent to prompt the installer to check and reinstall the defibrillation electrode sheet.

[0109] In the normal placement state, the defibrillation electrode piece is not installed on the defibrillation device. For humidity detection, the external wireless device transmits power and humidity signal detection instructions to the wireless transmission module of the humidity detection module of the electrode piece, and starts the humidity detection module to perform humidity detection work. For impedance detection, the impedance detection module connection end outside the packaging bag is connected to the external impedance detection device, and the external impedance detection device provides a signal (current, voltage) for impedance detection for the impedance detection module.

[0110] The defibrillation device (or external impedance detection device) provides a current signal to the impedance detection module of the electrode piece, and a loop is formed by the defibrillation device (or external impedance detection device), connection line, impedance detection module connection end, voltage measurement point, conductive gel, and metal foil or textile electrode.

[0111] The impedance detection module is provided with a protection circuit to prevent the influence on the impedance detection module during defibrillation. The defibrillation device / external impedance detection device calculates the impedance value of the conductive gel by detecting the voltage and current between the two voltage measurement points, or calculates the impedance value of the conductive gel by detecting the capacitance between the two capacitance measurement points and the provided voltage value (when using AC impedance detection method).

[0112] The impedance detection module has two detection methods: using DC signal and AC signal.

[0113] When performing electrocardiogram measurement and defibrillation work, the protection circuit of the impedance detection module will work to prevent the energy during defibrillation from affecting the impedance detection module.

[0114] Referring to Figure 6 , the method of using DC signal for conductive gel impedance detection can be (taking impedance detection when the defibrillation electrode piece is installed on the defibrillation device as an example):

[0115] The defibrillation electrode piece is installed on the defibrillation device, and the remote monitoring platform sends an impedance detection instruction to the defibrillation device. After receiving the impedance detection instruction, the defibrillation device provides a fixed value of current which sequentially passes through the electrode piece connection end, connection line, impedance detection module connection end, connection line connected to the conductive piece on the first voltage measurement point 1-1, 1-2 of one end of the two electrode pieces, respectively. Then the current signals on the left and right electrode pieces are transmitted to the conductive pieces on the second voltage measurement points 2-1, 2-2 through the conductive gel, and then the current signals are transmitted to the defibrillation device in sequence through the signal connection line, impedance detection module connection end, and electrode piece connection end. The voltage value of the signal connection line connected to the conductive piece of the voltage measurement point is measured on the defibrillation device, and the impedance value of the conductive gel is calculated according to the provided current value, and then the defibrillation device transmits the detected impedance signal to the remote monitoring platform.

[0116] In the case that the defibrillation electrode patch is not installed on the defibrillation device, an external impedance detection device can be used instead of the aforementioned defibrillation device, and the impedance detection module connection end is connected to the external impedance detection device, and the transmission mode of the current signal is consistent with the working mode when the aforementioned defibrillation device uses a direct current signal to perform impedance detection.

[0117] Referring to Figure 7 , the mode of using an alternating current signal to perform impedance detection of the conductive gel can be (for example, in the case of impedance detection when the defibrillation electrode patch is installed on the defibrillation device):

[0118] The two detection points of impedance detection under the alternating current signal are arranged on the left electrode patch and the right electrode patch, respectively, and the arrangement positions of the detection points can be the same as the monitoring point positions of impedance detection under the direct current signal, that is, for any electrode patch, any one of the two impedance detection points under the direct current signal can be used as the impedance detection point under the alternating current signal, or the impedance detection point under the alternating current signal can be arranged at other positions according to actual conditions. Similarly, a protection circuit should also be added to the impedance detection module for impedance detection using an alternating current signal to prevent the defibrillation energy from affecting the impedance detection module during defibrillation.

[0119] When the defibrillation electrode patch is installed on the defibrillation device, the remote monitoring platform sends an impedance detection instruction to the defibrillation device. After the defibrillation device receives the impedance detection instruction, the alternating current signal provided by the defibrillation device is sequentially connected to the conductive patch on the voltage measurement point 1-3 of the right electrode patch through the electrode patch connection end, the connection line, the impedance detection module connection end, and the connection line, and then the alternating current signal is transmitted to the conductive gel through the metal foil or the textile electrode connected to the voltage measurement point 1-3, respectively, and a capacitive environment is formed between the metal foil or the textile electrode of the left electrode patch and the right electrode patch. According to the characteristic that a capacitor blocks direct current and passes alternating current, the alternating current signal can be transmitted to the metal foil or the conductive gel of the left electrode patch, and then the alternating current signal is sequentially transmitted to the defibrillation device through the voltage measurement point 2-3 on the left electrode patch, the signal connection line, the impedance detection module connection end, and the electrode patch connection end. The voltage of the signal connection line connected to the conductive patch of the voltage measurement point is measured on the defibrillation device, the impedance of the conductive gel is calculated according to the provided current, and then the defibrillation device transmits the detected impedance signal to the remote monitoring platform.

[0120] In the case that the defibrillation electrode patch is not installed on the defibrillation device, an external impedance detection device can be used instead of the aforementioned defibrillation device, and the impedance detection module connection end is connected to the external impedance detection device, and the transmission mode of the current signal is consistent with the working mode when the aforementioned defibrillation device uses a direct current signal to perform impedance detection.

[0121] According to the number and parameter requirements of the wiring, a suitable connector or concentrator can be selected as the impedance detection connection end.

[0122] The humidity detection module detects the humidity of the conductive gel by detecting the humidity in the sealed package of the defibrillation electrode pad.

[0123] The humidity detection module can be installed on only one defibrillation electrode pad or on both electrode pads because it is used to detect the humidity in the environment of the packaging bag.

[0124] The humidity detection module is installed in the fixed cavity on the front of the first layer (the first general layer) of the defibrillation electrode pad. The signal connection line of the humidity detection module is led out through the small hole left on one side of the fixed cavity. The led-out connection line is further led out to the outside of the packaging bag through the connection line outlet on the defibrillation electrode pad packaging bag and connected to the electrode pad connection end.

[0125] The humidity detection module contains a humidity sensor and a control and wireless transmission module. The humidity detection module can receive a humidity signal detection instruction in a wired or wireless manner and send the detected humidity signal to the defibrillation device or external wireless device in a wired or wireless manner.

[0126] When the defibrillation electrode pad has been installed on the defibrillation device, data transmission can be performed with the defibrillation device and the remote monitoring platform. When the defibrillation electrode pad is not installed on the defibrillation device, an external wireless device can be used to send a humidity detection instruction and a power signal to the defibrillation electrode pad, start humidity signal detection, receive the detected humidity signal, and transmit the detected humidity signal to the remote monitoring platform through the external wireless device.

[0127] When the defibrillation electrode pad is installed on the defibrillation device, the humidity detection module can receive a humidity signal detection instruction from the defibrillation device in a wired or wireless manner and transmit the humidity signal to the defibrillation device in a wired or wireless manner. The defibrillation device transmits the humidity signal to the remote monitoring platform.

[0128] Specifically, it can be (see Figure 8): the remote monitoring platform sends a humidity signal detection instruction to the defibrillation device. After receiving the humidity signal detection instruction, the defibrillation device transmits a power signal to the control and wireless transmission module of the humidity detection module through the connection line connection end and the connection line, and the control and wireless transmission module receives the power signal and starts to work. After the control and wireless transmission module starts to work, it sends a start completion signal to the defibrillation device through the connection line. After receiving the start completion signal of the humidity detection module, the defibrillation device transmits a humidity signal detection instruction to the control and wireless transmission module of the humidity detection module through the connection line. After receiving the humidity signal detection instruction, the control and wireless transmission module provides a power signal and a humidity detection instruction to the humidity sensor, starts the humidity sensor to detect humidity, and then receives a humidity signal from the humidity sensor. The humidity sensor transmits the detected humidity signal to the control and wireless transmission module, and the control and wireless transmission module transmits the detected humidity signal to the defibrillation device through the connection line and the electrode patch connection end. The defibrillation device transmits the detected humidity signal to the remote monitoring platform.

[0129] In the state that the defibrillation electrode patch is not installed on the defibrillation device, the humidity detection module can be connected with the external wireless device in a wireless manner to detect the gel humidity of the defibrillation electrode patch.

[0130] Specifically, it can be (see Figure 9 ): the external wireless device of the packaging bag provides a power supply and a humidity detection instruction to the humidity detection module of the defibrillation electrode patch in a wireless transmission manner. After receiving the power signal and the humidity detection instruction, the control and wireless module of the humidity detection module provides a power supply and a humidity detection instruction to the humidity sensor to start humidity signal detection. The humidity sensor transmits the detected humidity signal to the control and wireless transmission module, and the control and wireless transmission module transmits the humidity signal to the external wireless device in a wireless transmission manner. At the same time, the external wireless device can transmit the humidity signal of the defibrillation electrode patch to the remote monitoring platform.

[0131] The external wireless device can send power signal and humidity signal detection instruction to the control and wireless transmission module of the humidity detection module in a wireless transmission manner outside the package of the defibrillation electrode sheet, for starting the control and wireless transmission module and controlling the humidity detection module to detect humidity. The control and wireless transmission module is started after receiving the power signal, and then controls the humidity sensor to detect humidity according to the received humidity detection instruction. The humidity sensor transmits the detected humidity signal to the control and wireless transmission module in a wired manner, and then the control and wireless transmission module transmits the detected humidity signal to the external wireless device in a wireless manner. The humidity in the package and the humidity of the conductive gel can be detected without opening the defibrillation electrode sheet package. At the same time, it is also convenient to check the effectiveness of the defibrillation electrode sheet which has been produced but not installed on the defibrillation device.

[0132] The pressing frequency detection module uses an acceleration sensor. The pressing frequency detection module (especially the acceleration sensor) is installed near the pressing position of the right electrode sheet. The pressing frequency detection module detects the pressing frequency during cardiopulmonary resuscitation and transmits the pressing frequency signal to the defibrillation device through the connecting line. The pressing frequency detection module can transmit the pressing frequency signal to the defibrillation device in a wired or wireless manner.

[0133] The pressing frequency detection module includes an acceleration sensor and a control and wireless transmission module. The acceleration sensor and its control and wireless transmission module are preferably installed on the second layer (the second general layer) of the defibrillation electrode sheet and do not contact the defibrillation layer. The face of the second layer close to the first layer is the front face. There are two fixed cavities on the front face of the second layer, and the acceleration sensor and its control and wireless transmission module are respectively placed in the two fixed cavities. The two fixed cavities are four-edge sealed, and a small hole is left on the side close to the connecting line exit of the defibrillation electrode sheet package for leading out the connecting line and the power signal connecting line; the pressing frequency detection signal connecting line and the pressing frequency detection instruction and power signal connecting line are led out through the small hole. Details

[0134] Referring to Figure 10 In the wired transmission mode, the three connecting lines on the acceleration sensor for transmitting the pressing frequency detection signal, the pressing frequency detection instruction and the power signal are led out from the small hole on the first fixed cavity (fixed cavity 1) and introduced into the control and wireless transmission module through the small hole on the second fixed cavity (fixed cavity 2). The two connecting lines between the control and wireless transmission module and the defibrillation device are led out at the small hole on the fixed cavity 2, and then finally connected to the electrode sheet connecting end through the connecting line exit of the defibrillation electrode sheet package. And the connecting line is connected to the defibrillation device through the electrode sheet connecting end.

[0135] When the cardiopulmonary resuscitation compression is started in the first aid process, the defibrillation device sends the power signal to the control and wireless transmission module of the defibrillation electrode through the connecting line and the electrode connecting end. After the control and wireless transmission module of the compression frequency detection module of the defibrillation electrode receives the power signal from the defibrillation device, the control and wireless transmission module is started, and the control and wireless transmission module sends the start success signal to the defibrillation device through the connecting line and the electrode connecting end. After the defibrillation device receives the start success signal, the defibrillation device sends the compression frequency detection instruction to the control and wireless transmission module of the compression frequency detection module. After the compression frequency detection module receives the compression frequency detection instruction from the defibrillation device, the compression frequency detection is started by providing the power signal and the compression frequency detection instruction to the acceleration sensor through the connecting line. The acceleration sensor transmits the detected compression frequency detection signal to the control and wireless transmission module in a wired manner through the connecting line, and the control and wireless transmission module transmits the detected compression frequency detection module to the defibrillation device in a wired manner through the connecting line and the electrode connecting end. Then the compression frequency signal is analyzed and displayed on the defibrillation device.

[0136] Referring to Figure 11 In the wireless transmission mode, the three connecting lines on the acceleration sensor for transmitting the compression frequency detection signal, the compression frequency detection instruction and the power signal are led out from the small holes in the first fixed cavity (fixed cavity 1) and introduced into the control and wireless transmission module on the small holes in the second fixed cavity (fixed cavity 2).

[0137] When the cardiopulmonary resuscitation compression is started in the first aid process, the defibrillation device provides the power signal to the compression frequency detection module of the defibrillation electrode. The wireless module of the defibrillation device sends the compression frequency detection instruction to the control and wireless transmission module of the defibrillation electrode. After the control and wireless transmission module of the compression frequency detection module of the defibrillation electrode receives the power signal from the defibrillation device, the control and wireless transmission module is started, and the control and wireless transmission module sends the start success signal to the wireless module of the defibrillation device. At the same time, the control and wireless transmission module provides the power signal and the compression frequency detection instruction to the acceleration sensor in a wired manner through the connecting line, and starts the compression frequency detection. Then the acceleration sensor transmits the detected compression frequency detection signal to the control and wireless transmission module of the compression frequency detection module, and the control and wireless transmission module transmits the detected compression frequency detection module to the wireless module of the defibrillation device in a wireless manner. The compression frequency signal is analyzed and displayed on the defibrillation device.

[0138] The electrode pad connecting end can be a multi-pin connector. On the basis of the existing multi-pin connector of the defibrillator, signal connecting lines and pins of the humidity detection module are added on both sides, mainly for transmitting humidity detection signals and start success signals, humidity detection instructions, and power supply signals required by the humidity detection module. Signal connecting lines and pins required by the impedance detection module are added, mainly for two signal connecting lines and two pins for transmitting fixed current to the defibrillation electrode pad, two signal connecting lines and two pins for receiving current from the defibrillation electrode pad. Signal connecting lines and pins required by the pressing frequency detection module are added, mainly for pressing frequency detection signals and start success signals, pressing frequency detection instructions, and power supply signals required by the pressing frequency detection module.

[0139] The electrode pad connecting line is used to connect the defibrillation device and the defibrillation electrode pad. The connecting line includes an electrode pad connecting end, an impedance detection module connecting end, and signal connecting lines connecting each module.

[0140] The electrode pad connecting end is connected to the defibrillation device through a hole seat or a pin on one side, and the other side leads out a connecting line for connecting each module in the defibrillation electrode pad. Among them, there are multiple independent signal connecting lines in the connecting line, which are used to transmit signals between each module and the defibrillation device. The signals transmitted in the connecting line include electrocardio signals, defibrillation energy, current signals used for impedance detection, humidity signals, impedance signals, pressing frequency signals, signals returned after each module receives power supply signals for startup, instruction signals for detecting humidity, and power supply signals provided for each module.

[0141] The connecting line connected to the impedance detection module is independently bundled inside the packaging bag, and is connected to the electrode pad connecting end through the impedance detection module connecting end outside the packaging bag. Then, it is connected to the defibrillation device together with other signal connecting lines.

[0142] The second mode is that the electrode sheet connecting end is set as a combination of multiple multi-pin connecting ends. The multiple multi-pin connecting ends include a multi-pin connecting end of an existing product, a humidity signal detection module connecting end, an impedance detection module connecting end, and a pressing frequency detection module connecting end. The four connecting ends can be combined for use according to the functions required by the actual product. The humidity signal detection module connecting end has signal connecting lines and pins on both sides of the humidity detection module, which are mainly used for transmitting humidity detection signals and starting success signals, humidity detection instructions, and power signals required by the humidity detection module. The impedance detection module connecting end has signal connecting lines and pins required by the impedance detection module on both sides, which are mainly used for two signal connecting lines and two pins for transmitting fixed currents to the defibrillation electrode sheet, and two signal connecting lines and two pins for receiving currents from the defibrillation electrode sheet. The pressing frequency detection module connecting end includes signal connecting lines and pins required by the pressing frequency detection module, which are mainly used for pressing frequency detection signals and starting success signals, pressing frequency detection instructions, and power signals required by the pressing frequency detection module.

[0143] The connection combination mode of the electrode sheet connecting end can be selectively combined. For example, the impedance detection module connecting end can be directly plugged into the defibrillation device by using a plug or other similar plug-in part, and the connecting line does not need to pass through the electrode sheet connecting end.

[0144] The upper connecting lines of the humidity signal detection module and / or the upper connecting lines of the pressing frequency detection module can also be provided with independent plugs, which are directly plugged into the defibrillation device or other upper devices. In this case, the independent plugs of these modules can also be regarded as electrode sheet connecting ends, that is, multiple electrode sheet connecting ends are used to implement the upper connection of the related modules.

[0145] The left and right electrode sheets of the defibrillation electrode sheet each have an electrocardiogram detection module and a defibrillation module. The defibrillation electrode sheet adds Ag+ to the conductive gel to improve the conductivity of the conductive gel and has the effects of sterilization and allergy prevention.

[0146] The defibrillation electrode sheet uses a textile electrode that is softer and better fits the human body. The fifth layer (the back of the defibrillation layer) of the defibrillation electrode sheet uses a textile electrode.

[0147] The electrocardiogram detection module of the defibrillation electrode sheet transmits the detected electrocardiogram signals to the defibrillation device through the connecting lines and the electrode sheet connecting end for analysis. When defibrillation is needed, the defibrillation device transmits defibrillation energy to the defibrillation layer of the defibrillation electrode sheet, and the defibrillation energy is transmitted to the human body through the conductive gel to perform defibrillation.

[0148] The present application adds various functions to the existing defibrillation electrode and defibrillation device / system, including the functions implemented by the impedance detection control module, the humidity detection control module and the compression frequency detection control module. The humidity detection control module should include both wired and wireless transmission methods, and the wireless transmission method should have the ability to transmit power signals.

[0149] The remote monitoring platform needs to add functions of sending humidity detection instructions and impedance detection instructions, and also needs to add functions of receiving and managing humidity detection signals and impedance detection signals, judging humidity signal and impedance signal data, and alarming abnormal data.

[0150] The appropriate information / data transmission method and components can be selected according to existing technology and actual needs. In appropriate cases, the wireless method can be changed to a wired method or the wired method can be changed to a wireless method.

[0151] The present application has the following characteristics:

[0152] A defibrillation electrode with compression frequency detection, humidity detection and sterilization functions is proposed. On the basis of maintaining the original two independent defibrillation electrodes, a compression frequency detection module is added to the right defibrillation electrode (right electrode) to detect the compression frequency during compression. The obtained compression frequency signal is transmitted to the defibrillation device by wireless or wired method, and the compression frequency is displayed on the defibrillation device, which has an indicating effect. The data processing process of the compression frequency detection module and the defibrillation device can be allocated according to existing technology and actual conditions, and the sensing signal (information) related to the compression frequency collected by the acceleration sensor or other motion or pressure sensor is converted into the compression frequency.

[0153] An impedance detection module is added to the defibrillation electrode to detect the impedance of the electrode gel. The impedance detection result is transmitted to the defibrillation device by wired method, and then transmitted to the remote monitoring platform by the defibrillation device. The data processing process of the impedance detection module and the defibrillation device can be allocated according to existing technology and actual conditions, and the related electrical signal between the detection points (connection points of the impedance detection module on the corresponding electrode) is converted into the impedance of the conductive gel. In one preferred embodiment, the impedance detection result of the defibrillation electrode is transmitted to the external device by wired method through an independent port.

[0154] Two impedance detection methods are proposed, including using an AC signal to test the impedance of the conductive gel of the defibrillation electrode by utilizing the capacitance characteristics, and adding a protection circuit to the impedance detection module to prevent the impedance detection circuit from being affected during defibrillation.

[0155] The defibrillation electrode piece is provided with a humidity detection module, which detects the humidity of the conductive gel by detecting the environmental humidity in the packaging bag of the electrode piece. For the defibrillation electrode piece produced and not installed for use, the humidity detection module receives the humidity signal detection instruction from the wireless device outside the packaging bag through wireless mode and transmits the humidity signal to the external wireless device through wireless mode. In one preferred embodiment, the remote monitoring platform sends the humidity signal detection instruction to the defibrillation device, the defibrillation device transmits the humidity signal detection instruction to the humidity detection module through wired or wireless mode, the humidity detection module detects the humidity according to the corresponding instruction, transmits the humidity signal to the defibrillation device through wired or wireless mode, and the defibrillation device transmits the humidity signal of the defibrillation electrode piece to the remote monitoring platform, so that the effectiveness of the defibrillation electrode piece is remotely detected, thereby reducing the maintenance cost of the defibrillation electrode piece.

[0156] The electrode piece can adopt a textile electrode with low Young's modulus, which can better adhere to the human skin and reduce the interference of motion artifacts on the electrocardio signal.

[0157] Ag+ is added to the conductive gel of the defibrillation electrode piece to improve the gel conductivity of the electrode piece, and the defibrillation electrode piece has a sterilization effect, so that the allergic reaction caused by the defibrillation electrode piece pasted on the human body is reduced.

[0158] The orientation expressions such as "upper", "lower", "back", "front" and the like in the present application are only used to define the relative position relationship of the relevant parts / structures, and do not constitute the orientation limitation in the field layout or use.

[0159] The preferred and optional technical means disclosed in the present application can be combined arbitrarily to form several different technical solutions, except for the special description and the further limitation of one preferred or optional technical means to another technical means.
