The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

As shown in fig. 1 to 15, the present embodiment provides a wearable cardiac defibrillator, which includes a vest 1, two defibrillation electrodes disposed on the vest 1, a monitor 3 and a pressing component 4, wherein the two defibrillation electrodes are electrically connected to the monitor 3 respectively, the monitor 3 is used for providing pulses for the two defibrillation electrodes, and the pressing component 4 is used for pressing the two defibrillation electrodes against the skin of a wearer 100. This wearing formula cardiac defibrillator's watch-dog 3 monitors wearing person 100 arrhythmia, when need defibrillate the heart urgently, compress tightly subassembly 4 at first and compress tightly two defibrillation electrodes on wearing person 100's skin, this setting can reduce the impedance between wearing person 100's skin and the defibrillation electrode, and then defibrillation electrode can more effectually carry out the defibrillation treatment to wearing person 100, and then the defibrillation electrode of having solved current wearing formula cardiac defibrillator can't compress tightly with wearing person 100 skin, and then lead to the impedance great, the poor problem of effect is defibrillated to wearing person 100 heart.

For the specific structure of the pressing assembly 4, optionally, two pressing assemblies 4 are provided, the pressing assembly 4 comprises an annular air bag 41 and a gas generator 42, and the gas generator 42 is connected with the monitor 3 and is used for inflating the annular air bag 41; two annular bladders 41 are provided in the vest 1, the two annular bladders 41 being respectively provided on the sides of the two defibrillation electrodes that are distal from the skin of the wearer 100. In this embodiment, when the wearer 100 wears the vest 1, both of the annular bladders 41 are fitted over the wearer 100. When the heart rate of the wearer 100 is not abnormal, the pressing component 4 is in a dormant state, the annular air bag 41 is in an air leakage state, pressing force cannot be generated on the wearer 100, and the comfort of the wearer 100 is improved. When monitor 3 detects that there is an abnormality in the heart rate of wearer 100 and it is necessary to defibrillate this wearer 100, monitor 3 controls gas generator 42 to inflate annular bladder 41. As the annular balloon 41 is inflated, the annular balloon 41 presses the defibrillation electrode disposed corresponding thereto against the skin of the wearer 100, and thus the impedance between the skin of the wearer 100 and the defibrillation electrode can be reduced.

For the specific structure of the gas generator 42, optionally, the gas generator 42 is disposed inside the annular bag 41; the gas generator 42 comprises an ignition device 421, a combustion tube 422, an ignition powder 424 and 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.

The amount of inflation of the annular bladder 41 required varies from wearer to wearer 100 due to the difference in body size. For this purpose, at least two gas generators 42 are optionally provided. In this embodiment, when the impedance between the defibrillation electrode and the skin surface of the wearer 100 does not meet the defibrillation requirement after the gas generating charges 423 in one gas generator 42 are completely burned, the remaining gas generators 42 are sequentially operated until the impedance between the defibrillation electrode and the skin of the wearer 100 meets the defibrillation requirement. In other embodiments, the gas generator 42 may be replaced with a gas pump.

And stopping inflating after the impedance requirement is met, and simultaneously performing defibrillation. After defibrillation is completed, the annular air bag 41 keeps an inflated state, the monitor 3 detects whether the heart rate of the patient recovers to a normal heart rate while the annular air bag 41 keeps the inflated state, and if the heart rate does not recover to the normal heart rate, defibrillation is continued on the patient. If the normal heart rate is restored, the gas in the annular air bag 41 is released.
