<p>Disclosed is an active type gas collection system. According to the present invention, a flow rate control valve is controlled through the proportional control which is conducted based on a predetermined pressure changed by the flow rate of an exhaust gas in a gas collection pipe, thereby precisely controlling the flow rate control valve depending on the deviation in the exhaust gas pressure supplied from an artificial ventilator or an anesthesia device. In addition, the proportional control of the flow rate control valve, which is opened or closed based on a pressure sensor signal value, is conducted, thereby collecting all of the exhaust gas of a patient despite a large deviation in the exhaust gas flow rate of the patient, minimizing the influence on the gas exhausting device (an artificial ventilator, an anesthesia device, etc.), and fundamentally reducing the overall size of a product considering the collected quantity of the exhaust gas. In addition, the load on a vacuum pump device can be also optimized, and thus unnecessary enlargement or excessive investment of the vacuum pumping device is not needed, thereby further improving economic feasibility.</p> |
