The invention provides a closed cardiac compression rhythm prompting device applicable to an automatic in-vitro defibrillator and a method thereof. The device comprises an ARM / DSP controller, a rhythm prompting module and a detection module, wherein a sound generation circuit, a light generation circuit and an image generation circuit in the rhythm prompting module are controlled by the ARM / DSP controller respectively; in the detection module, an excitation pulse generation and drive circuit, an electrocardioelectrode, a preposed difference pre-magnifying circuit, a diode detection and regulation circuit, a filter circuit, gain adjustment and potential transition and an A / D converting circuit are electrically connected in sequence; the A / D converting circuit is electrically connected withthe ARM / DSP controller; and the excitation pulse generation and drive circuit and the gain adjustment and potential transition are controlled by the ARM / DSP controller. The device and the method givean operator correct guidance through three prompting modes, namely sound, light and image, and give a specific prompt to incorrect compressing operation by detecting actual compressing rhythm and strength so as to prompt the operator to correct the incorrect operation in time.

The invention discloses a cardio-pulmonary resuscitation feedback control method and system, and relates to the technical field of medical care. The method comprises the steps of collecting brain oxygen signals of a patient; preprocessing the brain oxygen signals of the patient; separating out first signals and second signals from the preprocessed brain oxygen signals through independent componentanalysis, wherein the first signals are cardio-pulmonary resuscitation signals, and the second signals are spontaneous circulation signals; according to the first signals and the second signals, adjusting and controlling cardio-pulmonary resuscitation of the patient. By means of the method and system, the technical problems in the prior art that during cardio-pulmonary resuscitation, whether or not the patient restores spontaneous circulation is difficult to judge, cardio-pulmonary resuscitation has negative effects, and the patient cannot be effectively cured are solved. The curative rate ofcardio-pulmonary resuscitation can be greatly increased, and the method and system have the technical advantages of being high in pertinence, noninvasive, high in safety coefficient and easy to operate.

The invention discloses an intelligent cardio-pulmonary resuscitation assisting device. The intelligent cardio-pulmonary resuscitation assisting device comprises a wearable unit. The wearable unit comprises a housing and a special module installed in the housing. The special module comprises an acceleration sensor, a gravity sensor, a light emitting device and a sound production device which are arranged on the housing, and a microcontroller arranged in the housing and provided with a standard operation range value. The microcontroller is electrically connected with the acceleration sensor, the gravity sensor, the light emitting device and the sound production device. When the gravity sensor and the acceleration sensor detect that the downward pressing frequency and depth of the hand are within the standard operation range of cardio-pulmonary resuscitation, the microcontroller controls the light emitting device to emit light regularly and intermittently according to the standard operation range value, and controls the sound production device to count off according to the flickering of light emitted by the light emitting device. The invention further provides a using method of the intelligent cardio-pulmonary resuscitation assisting device. By the adoption of the intelligent cardio-pulmonary resuscitation assisting device, ordinary people can conduct cardio-pulmonary resuscitation.
