Summary of the invention
In order to overcome the shortcoming that prior art exists, it is accurate, safe and reliable that the purpose of this utility model provides a kind of metering, can accurately collect, measure tested anesthetic gases volume, accurately controls minute, accurately record anesthetic gases output concentration, and try to achieve the pick-up unit of narcosis gas output quantity.
The technical solution adopted in the utility model is: a kind of pick-up unit of narcosis gas output quantity comprises four solenoid valves, water tank, two collecting bags, tensimeter, variable valve, flowmeter, concentration tester, retaining valve, vacuum table, negative pressure pump; Be provided with two collecting bags that are immersed in fully in the water in the water tank, the bottom of two collecting bags is fixed on water tank bottom, and wherein a collecting bag is communicated with the P end of solenoid valve 1,3, and another collecting bag is communicated with the P end of solenoid valve 2,4; The R end of solenoid valve 1 is communicated with the A end of solenoid valve 2, and the R end of solenoid valve 4 is communicated with the A end of solenoid valve 3; The A end of solenoid valve 1 is connected to the common gas vent of Anesthesia machine, and the R of solenoid valve 2 is connected to sewage draining exit, and the R of solenoid valve 3 is connected to the normal concentration gas vent, and normal concentration gas is used for the corrected concentrations tester; The A end of solenoid valve 4 is communicated with tensimeter, variable valve, flowmeter to concentration tester, tensimeter is used for the gaseous tension in the measurement collection bag, revise gas volume, variable valve and flowmeter are regulated the anesthetic gases test traffic according to the requirement of concentration tester, and concentration tester is measured anesthesia gas concentration; The closed top end of water tank connects negative pressure pump and retaining valve, and negative pressure pump sets up in the water tank-the stable air pressure of 10KPa, retaining valve guarantees not produce normal pressure in the water tank, guarantees pressure stability.
During gas that the quick oxygen supply of solenoid valve 3 control test is preceding 1 minute and the quick oxygen supply in 10 seconds and 10 seconds-10KPa stablize gas during the gas pressure test;
The gas in 30 seconds after the quick oxygen supply of solenoid valve 4 control test ,-10KPa stablize air pressure 30 seconds afterwards gas.
For trying to achieve the comparability of narcosis gas output quantity, must accurately measure and control volume, delivery time and the gas concentration three elements of gas.The volume of anesthetic gases is to get with the drainage accurate measurement by two collecting bags in the water tank, and revises by the force value that tensimeter is measured; The break-make of anesthetic gases delivery time by the Single-chip Controlling solenoid valve realizes; The output concentration of anesthetic gases is regulated by variable valve and flowmeter and is stablized tested anesthetic gases flow, accurately measures through concentration tester.
The result who measures by above method tries to achieve anesthetic gases evaporated volume in the triphasic unit interval respectively, thereby the comparability of drawing, confirming, during oxygen supply fast and after or during air pressure fluctuation-10KPa, whether the output quantity increment of anesthetic gases above 20%.
After adopting above technical scheme, the beneficial effect that the utility model reaches is: this pick-up unit test philosophy is clear, metering accurately, by programmed control can accurately judge during the quick oxygen supply and after the narcosis gas output quantity increment whether meet the requirement of ISO8835-4:2004 " anesthetic steam conveying equipment " standard code, gas volume is accurate to 1%, the acquisition time of gas is accurate to 1%, in the concentration degree of accuracy to 5% of output anesthetic gases.This proving installation effectively solves Anesthesia machine and evaporator because of designing the improper harm that causes.
