[0047] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0048] As Figures 1 to 15As shown, the embodiment provides a wearable cardiac defibrillator, which comprises a vest 1, two defibrillation electrodes arranged on the vest 1, a monitor 3 and a compression assembly 4, the two defibrillation electrodes are electrically connected with the monitor 3 respectively, the monitor 3 is used for providing pulses for the two defibrillation electrodes, and the compression assembly 4 is used for compressing the two defibrillation electrodes on the skin of a wearer 100. When the monitor 3 of the wearable cardiac defibrillator detects that the wearer 100 has arrhythmia and needs to be defibrillated urgently, the compression assembly 4 first compresses the two defibrillation electrodes on the skin of the wearer 100, which can reduce the impedance between the skin of the wearer 100 and the defibrillation electrodes, so that the defibrillation electrodes can more effectively defibrillate the wearer 100, thereby solving the problem that the defibrillation electrodes of the current wearable cardiac defibrillator cannot be compressed on the skin of the wearer 100, thereby resulting in large impedance and poor defibrillation effect on the heart of the wearer 100.

[0049] For the specific structure of the compression assembly 4, the compression assembly 4 is provided with two compression assemblies 4, the compression assembly 4 comprises a ring-shaped air bag 41 and a gas generator 42, the gas generator 42 is connected with the monitor 3 and is used for inflating the ring-shaped air bag 41, and the two ring-shaped air bags 41 are arranged on the vest 1 and are arranged on the sides of the two defibrillation electrodes away from the skin of the wearer 100. In the embodiment, when the wearer 100 wears the vest 1, the two ring-shaped air bags 41 are sleeved on the wearer 100. When the heart rate of the wearer 100 is normal, the compression assembly 4 is in a dormant state, at this time, the ring-shaped air bag 41 is in a deflated state, so that no compression force is generated on the wearer 100, which is beneficial to improve the comfort of the wearer 100. When the monitor 3 detects that the heart rate of the wearer 100 is abnormal and needs to be defibrillated, the monitor 3 controls the gas generator 42 to inflate the ring-shaped air bag 41. With the expansion of the ring-shaped air bag 41, the ring-shaped air bag 41 compresses the defibrillation electrode corresponding to the ring-shaped air bag 41 on the skin of the wearer 100, thereby reducing the impedance between the skin of the wearer 100 and the defibrillation electrode.

[0050] For the specific structure of the gas generator 42, the gas generator 42 is optionally arranged in the annular airbag 41; the gas generator 42 comprises an ignition device 421, a combustion tube 422, an ignition powder 424 and a gas generating powder 423, the combustion tube 422 is provided with an exhaust hole 4221, the gas generating powder 423 is arranged in the combustion tube 422, the ignition powder 424 is arranged in the combustion tube 422, the ignition device 421 ignites the ignition powder 424, and the ignition powder 424 ignites the gas generating powder 423. In this embodiment, after the ignition device 421 receives the ignition instruction of the monitor 3, the ignition device 421 applies an ignition current to the ignition powder 424. The ignition powder 424 burns under the action of the current pulse and ignites the gas generating powder 423. The gas generated after the ignition of the gas generating powder 423 is discharged into the annular airbag 41 through the exhaust hole 4221, and the annular airbag 41 expands after receiving the gas. The expanded annular airbag 41 pushes the defibrillation electrode to the human skin, and the defibrillation electrode is pressed on the human skin to contact the human skin. At this time, the automatic application of the defibrillation electrode is completed, and the patient can be defibrillated. In other embodiments, the gas generator 42 can also be arranged outside the annular airbag 41, and the exhaust hole 4221 is arranged in the annular airbag 41.

[0051] Because the body types of different wearers 100 are different, the required inflation amount of the annular airbag 41 is also different. For this purpose, the gas generator 42 is optionally provided with at least two. In this embodiment, when the gas generating powder 423 in one gas generator 42 is completely burned, and the impedance between the defibrillation electrode and the skin surface of the wearer 100 does not meet the requirement of defibrillation, the remaining gas generators 42 work in turn until the impedance between the defibrillation electrode and the skin of the wearer 100 reaches the requirement of defibrillation. In other embodiments, the gas generator 42 can be replaced by a gas pump.

[0052] For how to determine whether the impedance between the skin of the wearer 100 and the defibrillation electrode meets the requirement of defibrillation impedance, the monitor 3 is optionally provided with an impedance measurement circuit, the impedance measurement circuit is electrically connected to the two defibrillation electrodes respectively, the impedance measurement circuit applies a measurement current to the two defibrillation electrodes, and the defibrillation impedance is calculated according to the measurement current. If the defibrillation impedance does not meet the threshold requirement, continue to inflate the annular airbag 41, until the defibrillation impedance requirement is met, stop inflating, and continue to inflate if the impedance requirement is not met. Stop inflating when the impedance requirement is met, and defibrillate at the same time. After the defibrillation is completed, the annular airbag 41 remains in the inflated state. While the annular airbag 41 remains in the inflated state, the monitor 3 detects whether the heart rate of the patient has returned to the normal heart rate. If not, continue to defibrillate the patient. If the normal heart rate is restored, release the gas in the annular airbag 41.

[0053] To ensure that the annular air bag 41 always presses the defibrillation electrode against the skin of the wearer 100 when inflated, the pressing assembly 4 optionally further comprises two limiters, which respectively fix the corresponding annular air bag 41 to the two defibrillation electrodes. In this embodiment, the two ends of one of the limiters are respectively fixed to the corresponding defibrillation electrodes, and the annular air bag 41 is arranged in a hole formed by the limiter and the corresponding defibrillation electrode.

[0054] When the defibrillation electrode is in long-term contact with the skin of the wearer 100, moisture will be generated between the skin and the defibrillation electrode, which will affect the defibrillation of the wearer 100 by the defibrillation electrode when the humidity exceeds a preset range. To maintain the humidity between the skin and the defibrillation electrode within the preset range, the monitor 3 optionally comprises a power supply 31, a controller 32, and a pump body 33, and the controller 32 is connected to the power supply 31. It should be noted that the controller 32 is the MCU shown in Figure 6 The defibrillation electrode comprises an electrode body 21 and a connecting line 22. The electrode body 21 is a hollow structure, and the side wall in contact with the skin of the wearer 100 is an electrode plate 211. The two ends of the connecting line 22 are respectively connected to the electrode plate 211 and the power supply 31. The electrode body 21 is connected to a first joint and a second joint 212, which are respectively in communication with the hollow structure. The electrode plate 211 is provided with a plurality of air holes 2111 arranged at intervals. The pump body 33 pumps gas into the hollow structure from the first joint. In this embodiment, when the humidity exceeds the preset range, the controller 32 controls the pump body 33 to work, and then pumps external gas into the hollow structure from the first joint and out from the second joint 212. In this process, the flowing gas carries away the moisture between the electrode body 21 and the skin of the wearer 100 through the air holes 2111, until the humidity between the electrode body 21 and the skin of the wearer 100 is within the preset range.

[0055] Optionally, the air holes 2111 are arranged in an array. In this embodiment, the air holes 2111 form more edges, which can reduce the problem of local arc burns on the skin caused by high voltage during discharge.

[0056] Specifically, the defibrillation electrode further comprises a temperature sensor and a humidity sensor, and the monitor 3 detects the temperature and humidity between the defibrillation electrode and the skin of the wearer 100 through the temperature sensor and the humidity sensor.

[0057] Specifically, the power supply 31 comprises a high-voltage boost circuit and a capacitor C, and the monitor 3 further comprises a discharge circuit. When the patient has a malignant arrhythmia (including ventricular fibrillation and ventricular tachycardia), the high-voltage boost circuit charges the capacitor C. After the charging of the capacitor C is completed, the discharge circuit implements biphasic defibrillation on the human body through the defibrillation electrode.

[0058] Specifically, the defibrillation electrode further comprises a gas pipe 23, the connecting line 22 enters the cavity structure from the first joint, the gas pipe 23 is sleeved on the connecting line 22 and one end of the gas pipe 23 is communicated with the first joint and the other end of the gas pipe 23 is communicated with the outlet of the pump body 33. In the embodiment, one end of the gas pipe 23 is inserted into the first joint and the other end of the gas pipe 23 is inserted into the outlet of the pump body 33. The gas pipe 23 is arranged in a spaced manner with the connecting line 22 in the cavity structure. One end of the connecting line 22 is electrically connected with the electrode body 21 after entering the cavity structure from the first joint.

[0059] In order to further reduce the impedance between the electrode body 21 and the skin of the wearer 100, optionally, the defibrillation electrode further comprises a first electromagnetic valve 24, the monitor 3 further comprises a liquid storage tank 34 and an electromagnetic valve group, specifically, the electromagnetic valve group comprises a second electromagnetic valve 35 and a third electromagnetic valve 36, the first electromagnetic valve 24 controls the opening and closing of the second joint 212, the inlet of the pump body 33 is provided with a first branch 37 and a second branch 38, the first branch 37 is communicated with the liquid storage tank 34 and the second branch 38 is communicated with the environment, the second electromagnetic valve 35 and the third electromagnetic valve 36 respectively control the opening and closing of the first branch 37 and the second branch 38, and the first electromagnetic valve 24, the second electromagnetic valve 35 and the third electromagnetic valve 36 are respectively connected with the controller 32. In the embodiment, the liquid storage tank 34 stores conductive glue. When the controller 32 detects that the heart rate of the wearer 100 is abnormal and needs to implement the cardiac defibrillation on the wearer 100, the controller 32 controls the first electromagnetic valve 24 to be in a closed state, controls the third electromagnetic valve 36 to be in a closed state, opens the second electromagnetic valve 35, and at the same time, the pump body 33 pumps the conductive glue out through the first branch 37 and pumps the conductive glue into the cavity structure through the gas pipe 23. Since the second joint 212 is in a closed state, the conductive glue entering the cavity structure reaches between the electrode body 21 and the skin of the wearer 100 through the air holes 2111. In turn, the impedance between the electrode body 21 and the skin of the wearer 100 can be further reduced. When it is needed to control the humidity between the electrode body 21 and the skin of the wearer 100, it is only needed to open the first electromagnetic valve 24 and the third electromagnetic valve 36. At the same time, the second electromagnetic valve 35 is closed.

[0060] In daily life and work, the wearer 100 often has some bending actions. In order to make the defibrillation electrode adhere to the skin of the wearer 100 and adhere to the physiological curvature of the waist side, optionally, the electrode body 21 is provided with a plurality of electrode bodies 21 which are sequentially hingedly arranged. In the embodiment, the plurality of electrode bodies 21 are sequentially hingedly arranged so that the defibrillation electrode adjusts its shape according to the posture of the wearer 100, thereby ensuring that the defibrillation electrode always adheres to the skin of the wearer 100.

[0061] Optionally, the monitor 3 further comprises a heart monitor 5, which is in communication connection with the controller 32, and is arranged on the chest of the vest 1 and the human body, and is used for monitoring the heart rate of the wearer 100. In this embodiment, the heart monitor 5 is in wired or wireless communication connection with the controller 32.

[0062] For the specific structure of the heart monitor 5, the heart monitor 5 comprises a heart sound sensor 51, a processor, an electrocardiogram sensor 52, a battery, a wireless communication module and two monitoring electrodes 53 in an optional manner; the two monitoring electrodes 53 are respectively attached to or implanted in the skin of the wearer 100, and the electrocardiogram sensor 52 detects the electrocardiogram signal of the heart of the wearer 100 through the two monitoring electrodes 53, and the heart sound sensor 51 can directly monitor the heart sound signal of the human body. The processor calculates the heart rate through the heart sound signal and the electrocardiogram signal respectively, and transmits the signal to the controller 32 through the wireless communication module, and the controller 32 judges whether malignant arrhythmia (including ventricular fibrillation and ventricular tachycardia) occurs according to the heart rate detected by the two sensors, and issues a shock warning if malignant arrhythmia (including ventricular fibrillation and ventricular tachycardia) occurs. In this embodiment, the heart rate is calculated through the electrocardiogram signal and the heart sound signal respectively, and then the heart rate detected by the electrocardiogram sensor 52 and the heart rate detected by the heart sound sensor 51 are compared, and if the heart rates monitored by the two are both abnormal, it can be determined that the wearer 100 has malignant arrhythmia, which can improve the accuracy of heart rate monitoring.

[0063] In order to prevent the heart monitor 5 from making false detection, the wearable heart defibrillator further comprises a feedback module 6, which is in communication connection with the monitor 3, and the feedback module 6 comprises an alarm and a defibrillation button. In this embodiment, when the monitor 3 determines that the heart monitor 5 monitors malignant arrhythmia, the monitor 3 gives the defibrillation button of the feedback module 6 a command of whether to shock, if the defibrillation button is actuated within a preset time, the defibrillation is cancelled, and if the button is not actuated within the preset time, the defibrillation is implemented through the defibrillation electrode. At the same time, the alarm comprises a display screen and an alarm, and the alarm reminds the wearer 100 whether the heart rate is in a malignant abnormal state, and the display screen displays the health information of the heart rate and the state information of the wearable heart defibrillator (such as the remaining battery capacity, the amount of conductive glue in the liquid tank 34, etc.).

[0064] Optionally, the feedback module 6 is provided with a second fixing member which can be worn on the wrist of the wearer 100. In this embodiment, the feedback module 6 is arranged at the wrist to facilitate the wearer 100 to view and operate. Specifically, the second fixing member is arranged at the wrist of the vest 1, and the second fixing member is a storage bag, the feedback module 6 is placed in the storage bag, and the storage bag has an opening or a transparent flexible panel which can be operated by the wearer 100, so as to facilitate the wearer to observe or operate the feedback module 6 through the opening or the transparent flexible panel. In other embodiments, the second fixing member can also be a wristband, etc.

[0065] Optionally, the feedback module 6 is wired to the monitor 3, and the wire is arranged in the hidden passage 11 of the vest 1 at the arm part. In other embodiments, the feedback module 6 can also be wirelessly connected to the monitor 3. The feedback module 6 can be designed in a bracelet structure.

[0066] Optionally, one of the defibrillation electrodes is arranged at the chest region of the front side of the vest 1, and the other defibrillation electrode is arranged at the waist region of the front side or the side of the vest 1, and the monitor 3 is provided with a third fixing member capable of being worn on the upper arm of the wearer 100. In this embodiment, the arrangement can facilitate the daily life and rest of the wearer 100. Arranging the two defibrillation electrodes at the chest of the wearer 100 and the waist region of the front side or the side of the wearer 100 can facilitate the rest of the wearer 100, and the back of the wearer 100 will not be compressed. At the same time, arranging the liquid storage tank 34 in the monitor 3 can reduce the volume of the defibrillation electrode. In addition, the defibrillation electrodes are arranged at the chest and the waist of the patient, and the defibrillation vector formed by the defibrillation electrodes when discharging can cover most of the myocardium.

[0067] Arranging the monitor 3 on the upper arm will not affect the normal work and life of the wearer 100. Specifically, the third fixing member can be a pocket, a fixing band, a clamping member, a magnetic member, or the like arranged on the vest 1.

[0068] Optionally, the vest 1 is provided with a hidden passage 11, and the connecting line 22 and the air tube 23 are arranged in the hidden passage 11. One end of the connecting line 22 is connected to the monitor 3, and the other end of the connecting line 22 is connected to the electrode body 21. In this embodiment, the hidden passage 11 can hide the connecting line 22 and the air tube 23 on one hand, and can prevent interference with the normal activities of the wearer 100 on the other hand. Specifically, the hidden passage 11 can be arranged on the side of the vest 1 close to the skin of the wearer 100, or can be arranged on the side of the vest 1 away from the skin of the wearer 100.

[0069] Optionally, the vest 1 further comprises a fixing member 12, and the fixing member 12 fixes the connecting line 22 and the air tube 23 in the hidden passage 11. In this embodiment, the fixing member 12 can prevent the connecting line 22 and the air tube 23 from sliding in the hidden passage 11, thereby affecting the movement of the defibrillation electrode and the monitor 3.

[0070] Optionally, the defibrillation electrode further comprises a spiral wire 25, one end of the spiral wire 25 is connected to one end of the connecting line 22, and the other end of the spiral wire 25 is connected to the electrode body 21. In this embodiment, the spiral wire 25 can be stretched and contracted under the action of an external force, so that when the wearer 100 performs a large amplitude movement, the spiral wire 25 can prevent the lead from pulling the electrode, and prevent the electrode from falling off due to pulling.

[0071] The monitor 3 also includes a communication and programming module, which includes Bluetooth communication, WIFI and other known communication methods to communicate with a programming device, which is used to provide the physician / manufacturer personnel with the basic information of the wearable cardiac defibrillator, and the programming device communicates the data in the wearable cardiac defibrillator to the internal storage of the programming device through communication, or transmits the information of the wearable cardiac defibrillator to the cloud through the programming device.
