Problems solved by technology

[0002] The solenoid valve of the ventilator for critically ill patients is the key component of the ventilator, and the control circuit of the solenoid valve is the heart part of the solenoid valve of the ventilator. It is economical, practical, safe and reliable. Its cost is only a few hundred yuan, and it is only a thousand yuan to enter the market. At present, the price of ventilators on the market is around ten thousand yuan, which is difficult for low-income patients in mountainous and remote areas of our country to accept.

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.

Description

technical field [0001] The invention relates to a control circuit for a solenoid valve of a ventilator for critically ill patients, which belongs to medical equipment. Background technique [0002] The solenoid valve of the ventilator for critically ill patients is the key component of the ventilator, and the control circuit of the solenoid valve is the heart part of the solenoid valve of the ventilator. The ventilator is economical, practical, safe and reliable. Its cost is only a few hundred yuan, and it is only a thousand yuan to enter the market. However, the current price of ventilators on the market is around 10,000 yuan, which is difficult for low-income patients in mountainous and remote areas of our country to accept. Contents of the invention [0003] Aiming at the above market situation, the present invention provides a control circuit for a solenoid valve of a ventilator for critically ill patients, which determines the price advantage of the complete ventilato...
