Problems solved by technology

[0003] The defibrillator and external pacemaker technology that is widely used now have the following problems and shortcomings in the design: 1. The current defibrillator is only suitable for patients with cardiac arrest and ventricular fibrillation, and cannot be used for the presentation of ECG without ventricular fibrillation First aid for patients with sudden death in a straight line; 2. Its function is limited to defibrillation, without the function of pacing the heart, so the scope of application of its cardiac resuscitation is limited and the success rate is low; 3. The installation of a

Embodiment 1

[0035] Please refer to figure 1 , an artificial atrial fibrillation cardiac resuscitation device, which is used in combination with a defibrillation device, and its work flow is as follows: Sudden cardiac death patient has ventricular fibrillation - defibrillation immediately, ventricular fibrillation disappears, ventricular rate appears but cannot be sustained - artificial atrial fibrillation is activated Fibrillation and pacing function module (rated current power, discharge time, and the selection of specific preset discharge points for the R wave of the electrocardiogram)—discharge the heart through electrodes placed on specific parts of the human body surface——synchronize the electrocardiogram oscilloscope during the entire operation process Display - automatically cut off the power after the heart beats, and the resuscitation is successful. The discharge power for one operation starts from 10 joules and reaches a maximum of 50 joules. The minimum number of discharges is...

Embodiment 2

[0037] When there is no ventricular fibrillation in a patient with sudden cardiac death, the ECG is in a straight line; after a short period of R wave after defibrillation, the ECG cannot continue to be in a straight line—after artificial heart compression, mouth-to-mouth breathing, and ventilator; intracardiac drug injection or high-frequency low-power Measures such as continuous electrical stimulation stimulate the R wave to start the artificial atrial fibrillation pacing function module to enter the resuscitation procedure in Example 1.

Embodiment 3

[0039] An artificial atrial fibrillation cardiac resuscitation system mainly consists of a charging / discharging / synchronizing circuit device for inducing atrial fibrillation, an ECG monitoring device, a feedback power-off circuit device, positive and negative electrodes, an ECG signal amplification / display circuit, an ECG recorder, etc. composition.

[0040] The artificial atrial fibrillation cardiac resuscitator adopts the RLC damping discharge method. The voltage converter converts the DC low voltage into a pulse high voltage, and charges the energy storage capacitor after high voltage rectification, so that the capacitor can obtain a certain amount of energy storage. After the current power, discharge time and a specific time point after the discharge is synchronized with the R-wave descending segment on the electrocardiogram, the electrodes are used to discharge the corresponding parts of the human body outside the body to achieve artificial atrial fibrillation. The bidire...

Abstract

The invention discloses an artificial atrial fibrillation cardiac resuscitation device and a control method thereof. The invention relates to a medical instrument for cardiac resuscitation during sudden cardiac death, the invention discloses the artificial atrial fibrillation cardiac resuscitation device for a patient with no ventricular fibrillation during defibrillation of a defibrillator and the patient with heart beat which cannot be sustained after defibrillation; the artificial atrial fibrillation cardiac resuscitation device can artificially cause atrial fibrillation by performing low-power multi-time discharge within 0.03-0.06 second of R waves and implementing external electric shock after identifying R wave signals of an electrocardiogram induced by the device or by means of cardiac compression and the like. The atrial fibrillation occurring at the moment can be used as the most effective sinus node to replace pacing heartbeat. According to the invention, a pace-making function realized by artificial atrial fibrillation is added to the existing defibrillator. The cardiac resuscitation device has the advantages that atrial fibrillation is innovatively used for rescuing a sudden cardiac death patient, the cardiac resuscitation program is pushed forwards by one step, and the cardiac resuscitation success rate is increased. The device is wide in application range and simple to operate.

Description

technical field [0001] An artificial atrial fibrillation cardiac resuscitation device and its control method. The present invention relates to a medical device for cardiac resuscitation in case of sudden cardiac death, in particular to a device that enables the existing automatic cardiac defibrillator to have dual functions of eliminating ventricular fibrillation and cardiac pacing. first aid equipment. Background technique [0002] In the case of sudden cardiac death, most patients have ventricular fibrillation, and the defibrillator can eliminate the ventricular fibrillation and resuscitate the patient. Although some patients recovered their heartbeats, they eventually died because they could not continue. There are also a small number of patients with sudden cardiac death who do not have ventricular fibrillation, and there is a straight line on the electrocardiogram, so the defibrillator is useless. For two types of patients whose heartbeat recovers after defibrillation...
