Abstract

The invention relates to a respirator driven by a low-flow small-sized medical air compressor. The respirator comprises a PLC (Programmable Logic Controller) system, an oxygen channel and an air channel; oxygen from the oxygen channel and air from the air channel are mixed by an air-oxygen mixer and then transmitted to a patient; the oxygen channel and the air channel are respectively provided with a first electric control proportional valve, a second electric control proportional valve, a first flow sensor and a second flow sensor which are connected with the PLC system; a low-flow small-sized medical air compressor, the second electric control proportional valve, a Venturi device and the second flow sensor are arranged on the air channel in sequence; and the second electric control proportional valve and the second flow sensor are both connected with the PLC system. In the invention, the low-flow small-sized medical air compressor and the Venturi device are used together for providing air for the air channel of the respirator, therefore, the installation size of the respirator is reduced, use noise, power consumption and cost are reduced, the stable and safe use of the respirator is ensured and the long-term use requirement of patients is met.

Description

technical field [0001] The invention relates to a medical ventilator, in particular to a ventilator driven by a low-flow small medical air compressor. Background technique [0002] Traditional medical ventilators use high-pressure air and high-pressure oxygen gas, which are mixed directly through the PLC control system and delivered to the patient. When the pressure is 0.3 MPa, each gas must maintain a flow rate of at least 30 liters per minute. If equipped with medical air The power of the compressor must be more than 450W to meet the above technical requirements for pressure and flow. The air compressor is noisy and consumes a lot of power. It needs to be equipped with a corresponding device for purifying the air. The entire ventilator is bulky and expensive to use. If the power is cut off, a larger emergency power supply is required to drive a large air compressor, which takes up space and increases energy consumption. [0003] The Venturi device has been used in ventila...
