The invention provides a non-touch monitoring device for heart and lung activity, comprising a pulse producer for producing a high frequency harmonic wave impulse sequence, a remover for producing a detecting high frequency harmonic wave impulse sequence and a reference high frequency harmonic wave impulse sequence from the stated detecting high frequency harmonic wave impulse sequence, a transmitting antenna for transmitting the stated detected high frequency harmonic wave impulse sequence to the parts of the heart and lung of a person to be tested, a receiving antenna for receiving the stated detected high frequency harmonic wave impulse sequence scattered from the parts of the heart and lung, a balance mixer coupled with the stated receiving antenna for producing a signal of the heart and lung activity and a signal processing module coupled with the stated balance mixer. The stated balance mixer comprises a first input end for receiving the stated referencing high frequency harmonic wave impulse sequence and a second input end electric connected with the stated receiving antenna.
Description
technical field [0001] The invention relates to a non-contact cardiopulmonary activity monitoring device and a method for acquiring cardiopulmonary activity signals, in particular to a non-contact cardiopulmonary activity monitoring device and a cardiopulmonary activity signal acquisition method that uses a high-frequency sinusoidal pulse sequence to measure heartbeat and respiratory signals method. Background technique [0002] Respiratory disorders such as apnea or intermittent breathing often occur in premature infants. Breathing disorders can cause two symptoms: one mainly occurs in premature infants, also known as apnea of prematurity (AOP); the other is sudden infant death syndrome (SIDS) or Apparent life threatening event (ALTE). Untreated premature infants with premature apnea are at high risk of sudden infant death syndrome and are more likely to have accidents at home. Bradycardia and even a drop in blood pressure may cause hemodynamic chain reactions after br...
