Abstract
The invention discloses a human respiration stimulation device. The human respiration stimulation device takes a single-chip microcomputer as a core unit of a microprocessor, and can control switches of solenoid valves independently and remotely through an upper computer and by utilizing a WIFI network. The opening and closing of the solenoid valves make air bags charge and discharge to form abdomen and chest breathing fluctuations. The two groups of solenoid valves are in one-input three-output mode; and three outlets are different in air output amount, and work of each air port can be controlled independently, so that fluctuation of the abdomen and chest is allowed to be strong and weak. One group of solenoid valves provide two air bags to simulate the chest of a female, and the other group of solenoid valves provide one air bag to simulate the abdomen of a male; and since the fluctuation frequency and strength of the abdomen is different from the fluctuation frequency and strength of the chest, so that different physiological statuses are formed. Besides, an air pump can be in a working and stop two states according to the pressure intensity of the system, so that the whole system is allowed to be more stable and reliable. The human respiration stimulation device simulates the function of human respiration, can realize independent control and provides a high-simulation clinical situation for medical education practice.
