The invention discloses a control method of a breathing machine with a sputum excretion function and the breathing machine. The control method of the breathing machine with the sputum excretion function comprises the steps that when the breathing machine works in a breathing working mode, a first input end and an output end of an air path switching device are controlled to communicate, first airflow is output to a breathing pipeline, human respiration is assisted; and when the breathing machine works in an expectoration working mode, the first input end and the second input end of the air path switching device are controlled to alternately communicate with the output end, and the first air flow and the second air flow are alternately output to the breathing pipeline, so that positive and negative alternate ventilation of a human body is realized, and expectoration of the human body is assisted. According to the control method of the breathing machine with the sputum excretion function, multiplexing of the breathing auxiliary function and the expectoration auxiliary function of the breathing machine is achieved, in the process that a user uses the breathing machine, when expectoration is needed, the breathing machine can be immediately switched to the expectoration working mode, and expectoration assistance is achieved.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a ventilator control method and ventilator with expectoration function. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. [0003] However, the existing ventilator only has the breathing assistance function, and when the user needs to cough up sputum during breathing assistance, the ventilator cannot assist the user to cough up sputum. Contents of the invention [0004] The main purpose of the present invention is to provide a ventilator control method with expectoration function, aiming to realize the multiplexing...
