Abstract
The invention discloses a control circuit of a breathing machine electromagnetic valve for critically ill patients. The electromagnetic valve of the breathing machine for the critically ill patients is the critical component. The control circuit of the electromagnetic valve is the heart component of the breathing machine electromagnetic valve and determines the breathing frequency and the breathing ratio. The control circuit is economical and practical, the cost of the control circuit is only several hundred RMB, and the control circuit is no more than one thousand RMB in the market. Breathing machines in the current market are all ten thousand RMB or so, so that the breathing machines are not available for patients with low income. Due to the fact that the breathing machine for the critically ill patients is matched with the circuit and is low in price, safe and reliable, the breathing machine for the critically ill patients can be popularized in health centers in townships, villages and street communities, facilitates improvement of the national medical level and is composed of a numerical control circuit, an electromagnetic valve and an air supply system.
