Description
Technical field
The utility model relates to the gas concentration testing tool, particularly a kind of anesthesia evaporator gas concentration proving installation.
Background technology
Anesthesia evaporator is the important component part of Anesthesia machine, and its quality not only indicates the manufacture level of Anesthesia machine, also is related to effect and the success or failure of inhalation anesthesia, is directly involved in patient's safety.The ultimate principle of anesthesia evaporator is to utilize a certain amount of carrier gas to provide condition of negative pressure that anesthetic gases is brought in the carrier gas, and becoming has certain density anesthesia vapor stream, directly enters anaesthetic circuit.
State Food and Drug Administration has issued " YY 0635.3-2009 suction-type anesthesiaing system the 3rd part: anesthetic gases conveying device " on June 16th, 2009, and in formal enforcement on Dec 1st, 2010.This standard adopting by equation international standard ISO8835-4:2004.The output concentration of standard-required anesthesia evaporator and the deviation range of setting concentration be from-20% to 30%, perhaps can not above maximum scale value-5% to+7.5% between, both get maximal value.Under following two kinds of different test environments, test:
1) gas flow by anesthesia evaporator is 2L/min ± 0.2L/min, when inspiratory/expiratory is set as maximum for (1:2 ± 20%) and inhalation flow, respiratory rate is 15 times/min ± 2 time/min, introduces the pressure that maximum fluctuation is 2kPa ± 0.3kPa at gas vent;
2) gas flow by anesthesia evaporator is 8L/min ± 0.8L/min, when inspiratory/expiratory is set as maximum for (1:2 ± 20%) and inhalation flow, respiratory rate is 15 times/min ± 2 time/min, introduces the pressure that maximum fluctuation is 5kPa ± 0.4kPa at gas vent.
At present, the scheme that is commonly used to test is that the Anesthesia machine that directly provides with anesthesia evaporator producer is tested.This method just requires the testing staff to test different Anesthesia machines first, sees whether it can provide the test environment that satisfies standard-required, and test process is complicated and universal poor; Just can test the scattered and complicated operation of structure for also not needing to dispose anesthesia respirator with the Anesthesia machine of anesthesia respirator.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems, and a kind of detection and anesthesia evaporator gas concentration proving installation easy and simple to handle, efficiently and accurately that is suitable for the different model anesthesia evaporator is provided.
The technical solution of the utility model:
A kind of anesthesia evaporator gas concentration proving installation, by air-flow part, air pressure fluctuation adjusting part, mixed gas part of detecting, anesthesia evaporator and gas concentration proving installation occuring forms, the air-flow generating unit is divided and is comprised flow generator, solenoid valve and control device and ease gas flap valve, flow generator is connected by pipeline with solenoid valve and control device, and ease gas flap valve is located on the connecting tube; The air pressure fluctuation adjusting portion is divided and is comprised elastic bag and two retaining valves and consist of the loop by pipeline; Mixed gas part of detecting comprises that expansion box is connected with poppet valve and connects by pipeline; Solenoid valve and control device are connected with expansion box by pipeline, and the outlet conduit of anesthesia evaporator and connecting tube are connected; Connecting tube between two retaining valves is connected with expansion box by pipeline, and the admission line of gas concentration proving installation and connecting tube are connected.
Advantage of the present utility model and good effect:
1) design of this device anesthesia evaporator access port can be applicable at present common multiple anesthesia evaporator, and highly versatile can be realized gas concentration test in the anesthesia evaporator of efficiently and accurately, is particularly suitable for testing agency;
2) adopt consistent air-flow emergence pattern and air pressure fluctuation to regulate pattern, save classic method when test to the detection calibration link of test environment, can realize the test under the different test environments, and test flow velocity and the adjustable joint of air pressure, it is easier, efficient, accurate that gas concentration is detected.

Embodiment
Embodiment:
A kind of anesthesia evaporator gas concentration proving installation, by air-flow part, air pressure fluctuation adjusting part, mixed gas part of detecting, anesthesia evaporator and gas concentration proving installation occuring forms, the air-flow generating unit is divided and is comprised flow generator, solenoid valve and control device and ease gas flap valve, flow generator is connected by pipeline with solenoid valve and control device, and ease gas flap valve is located on the connecting tube; The air pressure fluctuation adjusting portion is divided and is comprised elastic bag and two retaining valves and consist of the loop by pipeline; Mixed gas part of detecting comprises that expansion box is connected with poppet valve and connects by pipeline; Solenoid valve and control device are connected with expansion box by pipeline, and the outlet conduit of anesthesia evaporator and connecting tube are connected; Connecting tube between two retaining valves is connected with expansion box by pipeline, and the admission line of gas concentration proving installation and connecting tube are connected.
Among this embodiment, solenoid valve and control device adopt the lung ventilator through calibration, and elastic bag and retaining valve partly adopt breathing circuit and simulated lung.
The testing procedure of this device is as follows:
1) at first forms whole device by interface and pipeline connecting components, and in anesthesia evaporator, inject narcotics;
2) regulate air-flow generation part by solenoid valve and control device, generation gas flow, inspiratory/expiratory, respiratory rate all meet the anesthesia evaporator carrier gas air-flow of standard-required, start anesthesia evaporator, unnecessary gas is overflowed by ease gas flap valve, air-flow monitoring means Real-Time Monitoring air flow rate parameter is to determine at any time the accuracy of carrier gas air-flow;
3) the adjustable pressure fluctuation is regulated part to produce the required patient end pressure surge of test, with simulation anesthesia evaporator astable respiratory air flow in actual use, the inspiratory phase mixed gas enters elastic bag through retaining valve, cause pressure rise in the gas circuit, gas returns gas mixing and through blowdown valve unnecessary gas is discharged through another retaining valve in the expiratory phase elastic bag, pressure falls after rise in the gas circuit, carrier gas mixed with anesthetic gases be stored in the expansion box, and export the pressure surge module to, finish simultaneously the function of the mixed gas discharge that the pressure surge module is returned;
