Description

Technical Field

[0002] Cardiopulmonary resuscitation is a series of actions to revive a patient from cardiac arrest by rapid and effective chest compressions to improve the patient's chance of survival after cardiac arrest. Since cardiac arrest may occur in a variety of environments, the patient's own physical condition is also different, and different rescuers may have different CPR training, experience and skills, how to implement effective and quality CPR is a great challenge.

[0003] For this reason, CPR assistive devices have appeared on the market to assist rescuers in performing CPR effectively and with quality. A sensor for detecting compression parameters is installed inside the CPR assistive device. When a patient has cardiac arrest, the rescuer places the CPR assistive device on the patient's chest, and then performs chest compressions on the patient indirectly by pressing the CPR assistive device. The CPR assistive device is connected to other medical devices, and the compression parameters detected by the CPR assistive device are transmitted to the medical device. After receiving the compression parameters, the medical device provides feedback to the rescuer through prompts to assist the rescuer in performing effective and quality CPR. Currently, the CPR assistive devices on the market generally only detect the rescuer's compression frequency and cannot meet clinical requirements. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, an embodiment of the present invention proposes a cardiopulmonary resuscitation auxiliary device 100, and the proposed cardiopulmonary resuscitation auxiliary device 100 includes a housing assembly 10, a bracket 20, a circuit board assembly 30 and at least one force sensor 40. The housing assembly 10 is used to receive pressure from a rescuer and to contact a patient. The bracket 20 is disposed in the housing assembly 10, and the bracket 20 includes a first side 20a facing the rescuer and a second side 20b facing the patient, and the bracket 20 has a circuit board mounting portion 21 and a protective portion 22, and the circuit board mounting portion 21 has an opening 211 facing the second side 20b. The force sensor 40 is connected to the first side 20a of the bracket 20 facing the rescuer, so as to monitor the pressing force of the rescuer. The circuit board assembly 30 is installed on the circuit board mounting portion 21 through the opening 211. The circuit board assembly 30 includes a computing device, a transmission device and at least one acceleration sensor. The acceleration sensor is used to monitor the acceleration value of the rescuer's compression process; the protection portion 22 is arranged on at least part of the periphery of the circuit board assembly 30, and protrudes toward the patient relative to the circuit board assembly 30, so that the protection portion 22 is used to withstand at least part of the compression force to reduce the compression force exerted on the circuit board assembly 30. The force sensor 40 is electrically connected to the circuit board assembly 30. The computing device is used to convert the signals monitored by the force sensor 40 and the acceleration sensor into compression parameter signals. The transmission device is used to receive the compression parameter signal from the computing device and output it.

[0043] Among them, the protection part 22 protrudes toward the patient relative to the circuit board assembly 30, which means that the protection part is closer to the patient relative to the side of the circuit board assembly 30 facing the patient. When the bracket 20 is pressed and moves toward the patient, the protection part 22 contacts the patient first relative to the circuit board assembly 30, thereby bearing at least part of the pressing force to protect the circuit board assembly 30.

[0044] In one embodiment, the cardiopulmonary resuscitation auxiliary device 100 is connected to an AED (Automated External Defibrillator) device via a transmission device, and the transmission device outputs a compression parameter signal to the AED device. After the AED device processes the signal, it sends feedback to the rescuer via a prompt device to assist the rescuer in performing quality cardiopulmonary resuscitation compressions to improve the patient's survival rate. Optionally, the prompt device can be, but is not limited to, a sound device, a light device, or a vibration device.

[0045] In one embodiment, the compression parameter signal includes a compression frequency signal and a compression depth signal. Specifically, the compression frequency signal and the compression depth signal can be obtained by the following method: the force sensor 40 can monitor the rescuer's compression force in real time, and the computing device fits the compression force curve according to the signal transmitted by the force sensor 40 to obtain the compression frequency signal. Combining the compression frequency signal and the acceleration value of the compression, a secondary integration is performed, and the computing device can obtain the compression depth signal in real time.

[0046] The cardiopulmonary resuscitation assisting device 100 proposed in the embodiment of the present invention, firstly, by setting a force sensor 40 and an acceleration sensor to measure the pressing force of the rescuer and the acceleration value of the pressing process, other pressing parameter values ​​except the pressing frequency can be calculated by fitting these two values, so that the cardiopulmonary resuscitation process of the rescuer can be monitored more accurately and comprehensively, which is conducive to providing more reasonable rescue guidance to the rescuer. Secondly, by setting the circuit board assembly 30 on the second side 20b of the bracket 20, the circuit board assembly 30 does not directly receive the pressing of the rescuer, which can effectively avoid the risk of the circuit board assembly 30 being deformed due to the force, resulting in the circuit inside the circuit board assembly 30 being broken. Furthermore, by setting a protective portion 22 on the second side 20b of the bracket 20 to reduce the pressing force on the circuit board assembly 30, the circuit board assembly 30 can be further prevented from being deformed significantly.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the shell assembly 10 includes an upper shell 11 and a lower shell 12, the upper shell 11 is arranged on the first side 20a of the bracket 20, the lower shell 12 is arranged on the second side 20b of the bracket 20 and is connected to the upper shell 11, and the bracket 20, the force sensor 40 and at least part of the circuit board assembly 30 are located in the space enclosed by the upper shell 11 and the lower shell 12.

[0048] In one embodiment, the upper shell 11 is made of a flexible material. In one embodiment, the upper shell 11 can be made of, but not limited to, rubber or foam. In actual rescue situations, the rescuer must perform at least 100 chest compressions per minute for high-quality cardiopulmonary resuscitation, and the compression depth of an adult patient must reach at least 5 cm each time, which is bound to cause fatigue to the rescuer. In this embodiment, by setting the upper shell 11 to be made of a flexible material with a certain degree of softness, the discomfort and reverse impact force of the rescuer during chest compressions can be reduced, thereby reducing the rescuer's fatigue.

[0049] In one embodiment, the lower shell 12 is made of a flexible material. In one embodiment, the lower shell 12 can be made of, but not limited to, rubber or foam. In this embodiment, the lower shell 12 has a certain degree of softness, which can improve the comfort of the cardiopulmonary resuscitation assisting device 100 in contact with the patient.

[0050] In one embodiment, the bracket 20 is made of a hard material. In one embodiment, the bracket 20 can be but is not limited to being made of hard plastic. In this embodiment, the amount of deformation generated by the rescuer during the pressing process is small, and the pressing force of the rescuer can be effectively transmitted to the patient. In addition, the circuit board assembly 30 can be prevented from being greatly deformed.

[0051] In one embodiment, the upper housing 11 and the lower housing 12 are separately provided and connected to each other. That is, during assembly, the upper housing 11 and the lower housing 12 are two different parts connected to form the housing assembly 10 .

[0052] In one embodiment, the upper shell 11 is bonded and fixed to the bracket 20. Of course, the upper shell 11 and the bracket 20 are not limited to being bonded and fixed. For example, in another embodiment, the upper shell 11 and the bracket 20 are fixed by ultrasonic welding.

[0053] In one embodiment, the lower shell 12 is fixed to the bracket 20 by bonding. Of course, the lower shell 12 and the bracket 20 are not limited to being fixed by bonding. For example, in another embodiment, the lower shell 12 and the bracket 20 are fixed by ultrasonic welding.

[0054] It should be noted that the upper shell 11 and the lower shell 12 do not need to be subjected to a high temperature environment during assembly, so as to avoid the high temperature environment affecting the performance of the force sensor 40. For example, in one embodiment, the force sensor 40 uses a thin film piezoresistive pressure sensor 40, and the thin film piezoresistive pressure sensor 40 is prone to warping under the influence of a high temperature environment, which will affect the detection performance of the force sensor 40.

[0055] Of course, the upper shell 11 and the lower shell 12 are not limited to being separated. For example, in another embodiment, the upper shell 11 and the lower shell 12 are integrally formed by encapsulation.

[0056] like Figure 1 As shown, in one embodiment, the upper shell 11 is provided with a first indicator mark, and the first indicator mark is used to indicate the placement position of the cardiopulmonary resuscitation assisting device 100 on the patient. In this embodiment, it is convenient for the rescuer to accurately and quickly place the cardiopulmonary resuscitation assisting device 100 on the patient, saving time for rescue. The first indicator mark can be but is not limited to a line or a pattern.

[0057] like Figure 5 As shown, in one embodiment, the circuit board mounting portion 21 includes a first receiving groove 212 formed by the second side 20b of the bracket 20 being recessed, the circuit board assembly 30 is received in the first receiving groove 212, and the side wall of the first receiving groove 212 forms the protection portion 22. In this embodiment, since the circuit board assembly 30 is received in the first receiving groove 212, the contact between the circuit board assembly 30 and the lower housing 12 can be reduced, so as to reduce the force applied by the lower housing 12 to the circuit board assembly 30 when the cardiopulmonary resuscitation auxiliary device 100 is used, and avoid the circuit board assembly 30 from being greatly deformed.

[0058] It should be noted that the circuit board assembly 30 is not limited to the first receiving groove 212. For example, in another embodiment, Figure 6 As shown, the circuit board mounting portion 21 includes a continuous or discontinuous first surrounding wall 213 formed by the second side 20b of the bracket 20, and the circuit board assembly 30 is accommodated in the accommodation space formed by the first surrounding wall 213, and the side wall of the first surrounding wall 213 forms the protection portion 22. Similarly, in this embodiment, since the circuit board assembly 30 is accommodated in the accommodation space, the contact between the circuit board assembly 30 and the lower housing 12 can be reduced, so as to reduce the force applied by the lower housing 12 to the circuit board assembly 30 when the cardiopulmonary resuscitation auxiliary device 100 is used, so as to avoid a large deformation of the circuit board assembly 30.

[0059] In one embodiment, the circuit board assembly 30 is bonded and fixed to the bracket 20. Of course, the circuit board assembly 30 and the bracket 20 are not limited to being bonded and fixed. For example, in another embodiment, the circuit board assembly 30 and the bracket 20 can be fastened by screws.

[0060] like Figures 1 to 3 As shown, in one embodiment, the bracket 20 is provided with a wiring hole 23, and the force sensor 40 is electrically connected to the circuit board assembly 30 through a sensor cable 41, and the sensor cable 41 passes through the wiring hole 23. In this embodiment, the length of the sensor cable 41 can be shortened, and the bracket 20 can form a protection for the sensor cable 41, so that the sensor cable 41 can form a stable connection.

[0061] like Figure 2 and Figure 5 As shown, in one embodiment, the second side 20b of the bracket 20 is provided with a first wiring groove 24, the first wiring groove 24 is connected to the wiring hole 23 and the first accommodating groove 21, and the portion of the sensor cable 41 located on the second side 20b of the bracket 20 is embedded in the first wiring groove 24. In this embodiment, the sensor cable 41 can be installed in a hidden manner to prevent the sensor cable 41 from being exposed and pulled to cause poor contact.

[0062] It should be noted that the sensor cable 41 is not limited to the wiring method of the wiring hole 23 described above. For example, in another embodiment, the bracket 20 is provided with a second wiring groove (not shown), and the second wiring groove extends from the first side 20a of the bracket 20 along the outer surface of the bracket 20 to the second side 20b of the bracket 20. One end of the sensor cable 41 is connected to the force sensor 40, and the other end of the sensor cable 41 bypasses the bracket 20 and is connected to the circuit board assembly 30. The sensor cable 41 is entirely embedded in the second wiring groove. In this embodiment, the sensor cable 41 can also be installed in a hidden manner.

[0063] like Figure 2As shown, in one embodiment, a continuous or discontinuous second surrounding wall 25 is convexly provided on the first side 20a of the bracket 20, and the force sensor 40 is positioned in the receiving space formed by the second surrounding wall 25. With this embodiment, the positioning and installation of the force sensor 40 is facilitated. It should be noted that the embodiment is not limited to the above. For example, in another embodiment, the first side 20a of the bracket 20 is recessed to form a second receiving groove, and the force sensor 40 is received in the second receiving groove. This embodiment can also facilitate the positioning and installation of the force sensor 40.

[0064] like Figure 1 As shown, in one embodiment, the transmission device includes a transmission line 50 electrically connected to the computing device. The transmission line 50 extends out of the housing assembly 10 to be electrically connected to other medical devices, such as an AED device. That is, in this embodiment, the transmission device transmits signals by wired transmission.

[0065] It should be noted that, in the present embodiment, the transmission line 50 may include a power supply core line, and the AED device supplies power to the circuit board assembly 30 through the transmission line 50 .

[0066] like Figure 1 and Figure 5 As shown, in one embodiment, the second side 20b of the bracket 20 is provided with a third wiring groove 26, and the transmission line 50 is embedded in the third wiring groove 26. In this embodiment, the transmission line 50 can be installed in a hidden manner to prevent the transmission line 50 from being exposed and pulled to cause poor contact.

[0067] Of course, the transmission device is not limited to a wired method. For example, in another embodiment, the transmission device includes a wireless transmission module electrically connected to the computing device. That is, in this embodiment, the transmission device transmits signals by wireless transmission. It should be noted that when the transmission device adopts a wireless transmission method, the cardiopulmonary resuscitation auxiliary device 100 may also include a power module, which is arranged inside the housing assembly 10 to supply power to each module.

[0068] In one embodiment, the proposed cardiopulmonary resuscitation assisting device 100 is a disposable cardiopulmonary resuscitation assisting device 100 .

[0069] like Figure 1 , Figure 7 and Figure 8 As shown, the embodiment of the present invention further provides a cardiopulmonary resuscitation assisting device 100, which includes a housing assembly 10, a bracket 20, a circuit board assembly 30 and at least one force sensor 40. The housing assembly 10 is used to receive pressure from a rescuer and to contact a patient. The bracket 20 is disposed in the housing assembly 10. Figure 8As shown, the support 20 includes a first side 20a facing the rescuer, a second side 20b facing the patient, and a third side 20c, which is adjacent to the first side 20a or the second side 20b. The bracket 20 has a circuit board mounting portion 21 and a protective portion 22. The circuit board mounting portion 21 has an opening 211. At least one force sensor 40 is connected to the first side 20a of the bracket 20 facing the rescuer to monitor the pressing force of the rescuer. The circuit board assembly 30 is installed on the circuit board mounting portion 21 through the opening 211. The circuit board assembly 30 includes a computing device, a transmission device and at least one acceleration sensor. The acceleration sensor is used to monitor the acceleration value of the rescuer's pressing process; the protective portion 22 is arranged on at least part of the periphery of the circuit board assembly 30, and protrudes toward the patient or the rescuer relative to the circuit board assembly 30, so that the protective portion 22 is used to withstand at least part of the pressing force to reduce the pressing force exerted on the circuit board assembly 30. The force sensor 40 is electrically connected to the circuit board assembly 30. The computing device is used to convert the signals monitored by the force sensor 40 and the acceleration sensor into compression parameter signals. The transmission device is used to receive the compression parameter signals from the computing device and output them.

[0070] The protrusion of the protection portion 22 toward the patient relative to the circuit board assembly 30 can be referred to the above description, which is not repeated here. The protrusion of the protection portion 22 toward the rescuer relative to the circuit board assembly 30 means that the protection portion 22 is closer to the rescuer relative to the side of the circuit board assembly 30 facing the rescuer, and the rescuer first contacts the protection portion 22 when applying force, and the protection portion 22 bears at least part of the pressing force to protect the circuit board assembly 30.

[0071] Similarly, in this embodiment, by providing a protective portion on the bracket 20 to reduce the pressing force on the circuit board assembly 30, it is possible to avoid a large deformation of the circuit board assembly 30, which may lead to the risk of the circuit inside the circuit board assembly 30 being broken.

[0072] like Figure 7 As shown, in one embodiment, the opening 211 faces the first side 20a, and the cardiopulmonary resuscitation assisting device 100 further includes a cover plate 60, which covers the opening 211, and the side of the cover plate 60 facing away from the circuit board assembly 30 is flush with the first side 20a of the bracket 20, and the force sensor 40 is at least partially installed on the side of the cover plate 60 facing away from the circuit board assembly 30. The cover plate 60 can be, but is not limited to, a component formed after glue or epoxy resin is cured.

[0073] It should be noted that the opening 211 is not limited to being disposed on the first side 20a of the bracket 20. For example, in another embodiment, the opening 211 faces the second side 20b of the bracket 20. In this embodiment, the installation of the circuit board assembly 30 can refer to the above embodiment and will not be described in detail.

[0074] It should be noted that the opening 211 is not limited to being disposed on the first side 20a of the bracket 20 or the second side 20b of the bracket 20. For example, in another embodiment, Figure 8 As shown, the opening 211 faces the third side 20 c of the bracket 20 .

[0075] like Fig. 9 As shown, an embodiment of the present invention further provides a defibrillator 200, which includes an electrode assembly 210, a connecting bridge 220, and the cardiopulmonary resuscitation assisting device 100. The electrode assembly 210 includes a first electrode 2101 and a second electrode 2102. The first electrode 2101 and the second electrode 2102 are used to connect to a defibrillator to deliver the defibrillation shock generated by the defibrillator to a patient. The connecting bridge 220 connects the cardiopulmonary resuscitation assisting device 100 and the first electrode 2101, so that the positions of the cardiopulmonary resuscitation assisting device 100 and the first electrode 2101 remain relatively fixed.

[0076] The defibrillator device 200 proposed in this embodiment connects the cardiopulmonary resuscitation assisting device 100 and the first electrode 2101 by setting a connecting bridge 220, so that the positions of the cardiopulmonary resuscitation assisting device 100 and the first electrode 2101 remain relatively fixed. When the cardiopulmonary resuscitation assisting device 100 is correctly placed on the patient, the position of the first electrode 2101 on the patient is also synchronously determined. In this way, the operation time can be shortened and the rescue efficiency can be improved.

[0077] Specifically, during actual use, the cardiopulmonary resuscitation assisting device 100 is placed in alignment with the nipple midline and the sternum midline, and the first electrode 2101 is located below the clavicle and at a position corresponding to the right side of the patient's sternum.

[0078] It should be noted that the above-mentioned embodiment is for adult patients, and the proposed defibrillator 200 can also be applied to pediatric patients. However, the situation in which the proposed defibrillator 200 is applied to pediatric patients is different from that in which it is applied to adult patients. When applied to pediatric patients, it is necessary to first correctly place the first electrode 2101 and the second electrode 2102 on the front chest and back of the child according to the operating instructions, and then overlap the cardiopulmonary resuscitation assisting device 100 and place it on the upper surface of the electrodes at the front chest position. That is, when applied to pediatric patients, it is necessary to separate the first electrode 2101 and the cardiopulmonary resuscitation assisting device 100. Therefore, in one embodiment, if Fig. 9 As shown, the connection bridge 220 is provided with a tear line mark 2201, and the tear line mark 2201 is used to indicate the tearing position of the first electrode 2101 and the cardiopulmonary resuscitation auxiliary device 100. By providing the tear line mark 2201, the rescuer can be guided to tear the connection bridge 220 along the correct position.

[0079] In one embodiment, the connection bridge 220 may be provided with notches at both ends of the tear line mark 2201 , and the notches are used for rescuers to easily tear the connection bridge 220 along the tear line mark 2201 .

[0080] In one embodiment, the tear line mark 2201 is an easy-tear line, which can facilitate the rescuer to quickly tear the connecting bridge 220, save operation time, and improve rescue efficiency.

[0081] In one embodiment, the length of the connecting bridge 220 is adjustable. In actual use, the body shapes of adult patients may vary greatly. In this embodiment, the length of the connecting bridge 220 is adjustable, and the length of the connecting bridge 220 is adjusted so that the proposed defibrillator device 200 can be suitable for patients of different body shapes, thereby improving the convenience of use.

[0082] In one embodiment, the connecting bridge 220 includes at least a stretchable section, and the stretchable section is made of one of PE (polyethylene), PET (polyethylene glycol terephthalate) and PA (Polyamide). The above materials have the property of not being able to rebound after being stretched. When the patient is large, the connecting bridge 220 can be stretched so that the distance between the first electrode 2101 and the cardiopulmonary resuscitation assisting device 100 can be suitable for the patient.

[0083] It should be noted that the solution for changing the length of the connecting bridge 220 is not limited to the above-mentioned embodiment. For example, in another embodiment, Fig.10 As shown, the connecting bridge 220 includes a plurality of folding portions 221, which are connected in sequence and present a reciprocating bending structure. In a normal state, the plurality of folding portions 221 are in a folded state. When the patient is larger, at least part of the folding portions 221 can be unfolded to lengthen the connecting bridge 220.

[0084] In one embodiment, the surface of the folding portion 221 is provided with Velcro, and the rescuer can adjust the length of the connecting bridge 220 by sticking or tearing it.

[0085] It should be noted that the solution for changing the length of the connecting bridge 220 is not limited to the above-mentioned embodiment. For example, in another embodiment, Fig.11As shown, the connection bridge 220 includes a first connection portion 222 and a second connection portion 223, wherein the first connection portion 222 is connected to the first electrode 2101, and the second connection portion 223 is connected to the cardiopulmonary resuscitation assisting device 100, wherein the first connection portion 222 is movably connected to the second connection portion 223. That is, in this embodiment, by changing the relative positions of the first connection portion 222 and the second connection portion 223, the length of the connection bridge 220 can be changed.

[0086] like Fig.11 As shown, in one embodiment, the second connection part 223 is provided with a slide rail part 224, and the first connection part 222 is provided with a slide body 225, and the slide body 225 is slidably connected to the slide rail part 224. When the length of the connecting bridge 220 needs to be extended, the first connection part 222 and the second connection part 223 are pulled to make the slide body 225 and the slide rail part 224 move relative to each other.

[0087] It should be noted that the positions of the sliding body 225 and the sliding rail portion 224 can be swapped, that is, the second connecting portion 223 is provided with the sliding body 225 , and the first connecting portion 222 is provided with the sliding rail portion 224 .

[0088] like Fig.12 As shown, in one embodiment, the slide rail portion 224 includes a bottom plate 2241 and two side walls 2242 respectively arranged on opposite sides of the bottom plate 2241, and the two side walls 2242 are provided with slide grooves 2243 on opposite sides, and the slide body 225 can be slidably embedded in the two slide grooves 2243 on opposite sides.

[0089] It should be noted that the sliding body 225 and the sliding rail portion 224 can be made of hard materials, and the sliding body 225 and the sliding rail portion 224 have an interference fit. In this way, when the sliding body 225 is pulled to the specified position, the external force is removed, and the friction between the sliding body 225 and the sliding rail portion 224 allows the sliding body 225 and the sliding rail portion 224 to remain relatively stationary.

[0090] Of course, the slide body 225 and the slide groove 2243 are not limited to the above-mentioned interference fit, so that the slide body 225 and the slide rail portion 224 can remain relatively immobile after the external force is removed. For example, in another embodiment, the connecting bridge 220 also includes a retaining structure. After the slide body 225 slides to a specified position relative to the slide rail portion 224, the retaining structure retains the slide body 225 and the slide rail portion 224, so that the positions of the two remain fixed. The retaining structure can be, but is not limited to, a pin or a buckle structure.

[0091] It should be noted that the first connection part 222 and the second connection part 223 are not limited to being movably connected by the above-mentioned sliding body 225 cooperating with the slide rail part 224. For example, in another embodiment, one of the first connection part 222 and the second connection part 223 is provided with a plurality of in-line holes, and the other of the first connection part 222 and the second connection part 223 is provided with a plurality of in-line bosses, and the plurality of bosses are detachably arranged in the plurality of holes in a one-to-one correspondence. When the position of the connecting bridge 220 needs to be changed, the first connection part 222 and the second connection part 223 can be disassembled, the position of the boss and the hole can be changed, and then the boss and the hole can be buckled to achieve the change of the length of the connecting bridge 220.

[0095] Of course, the first electrode 2101, the second electrode 2102 and the cardiopulmonary resuscitation assisting device 100 are not limited to sharing one connector 230. In another embodiment, any two of the first electrode 2101, the second electrode 2102 and the cardiopulmonary resuscitation assisting device 100 share one connector 230, or the first electrode 2101, the second electrode 2102 and the cardiopulmonary resuscitation assisting device 100 each use a separate connector 230. The specific configuration can be determined based on actual design requirements.

[0096] like Fig.13As shown, in another embodiment, the defibrillator 200 further includes a first connector 231 and a second connector 232, the second connector 232 includes a first terminal 2321 and a second terminal 2322 detachably plugged with the first terminal 2321, the first electrode 2101, the second electrode 2102 and the first terminal 2321 are electrically connected to the first connector 231, and the cardiopulmonary resuscitation assisting device 100 is electrically connected to the second terminal 2322.

The protective layer 2105 may be, but is not limited to, a release paper. The protective layer 2105 is used to protect the conductive hydrogel layer 2106. When in use, the protective layer 2105 is torn off and the first electrode 2101 is pasted on the patient through the conductive hydrogel layer 2106. The conductive hydrogel layer 2106 is in direct contact with the patient and plays a conductive role. The conductive film layer 2107 is connected to the high-voltage wire in the cable. The defibrillation shock generated by the monitor is transmitted to the conductive film layer 2107 through the high-voltage wire, and the conductive film layer 2107 is transmitted to the patient through the conductive hydrogel layer 2106. The insulating film layer 2108 is used to protect the rescuer to prevent the rescuer from being shocked when the first electrode 2101 is defibrillated and discharged. The graphic printing layer 2109 is used to print the above-mentioned first pattern 2203 to guide the rescuer to correctly place the first electrode 2101.

[0098] In one embodiment, a double-sided adhesive layer is provided at the bottom of the cardiopulmonary resuscitation auxiliary device 100, and the protective layer 2105 mentioned above covers the conductive hydrogel layer 2106 and the double-sided adhesive layer. In this embodiment, the rescuer can tear off the protective layer 2105 of the first electrode 2101 and the protective layer 2105 of the cardiopulmonary resuscitation auxiliary device 100 at one time, shortening the operation time and improving the rescue efficiency. Of course, it is also possible to set the protective layer 2105 of the first electrode 2101 and the protective layer 2105 of the cardiopulmonary resuscitation auxiliary device 100 separately, which can be determined according to actual design needs.

[0099] The structure of the second electrode 2102 may refer to the first electrode 2101 and will not be described in detail here.
