Abstract
The utility model discloses an oxygen supply and attraction system detection apparatus in a medical center. The oxygen supply and attraction system detection apparatus comprises a pressure standard gauge, a boost valve, a pump control valve, a flowmeter, switches 7 and 8, and a micro-adjustor, wherein the flowmeter and the switches 7 and 8 jointly form a relatively closed pipe line, the pressure standard gauge communicates with the micro-adjustor through a pipe which communicates with a pressure source through the boost valve and communicates with vacuum source through the pump control valve, and the pipe communicates with the pipe line formed by the flowmeter and the switches 7 and 8. Oxygen pressure, oxygen flow or suction pressure and suction flow velocity can be measured once the oxygen supply and attraction system detection apparatus is plugged into from one end, thereby realizing simple and direct operation, saving manpower and material resources and effectively improving efficiency.
Description
Technical field
This utility model belongs to the medical equipment technical field, specifically relates to a kind of medical Central oxygen-supply and attraction system checkout gear.
Background technology
Medical Central oxygen-supply, attraction system are hospitals for making things convenient for patient and rehabilitation, improve work quality and efficient and newly-built armarium.Be widely used in each large, medium and small hospital in recent years.Form by equipment such as oxygenerator, negative pressure equipment, conveyance conduit, holding vessels, and be equipped with medical strong inspection measurement instruments such as a large amount of oxygen manometers, vacuum meter and float type oxygen inhalation apparatus.Because what this system carried is medical oxygen and filtered air, if the measurement instrument misalignment, safety index is defective and system's operation is undesired, with influencing patient's treatment and rehabilitation, seriously jeopardizes patient's life.
New through looking into, the not research of this project at present both at home and abroad.Carry out this technical body situation that detects business with regard to several families in the Shandong Province and see that what major part adopted is the detection of separate type.Directly measure during detected pressures, take out effusion meter again when needing to measure flow and measure with required pressure table or vacuum meter.According to the project of standard-required, to repeat to plug plug four times to each terminal, change oxygen manometer, oxygen flow meter, pressure vacuum gauge, four equipment of attraction effusion meter successively, whole process is very loaded down with trivial details.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of medical Central oxygen-supply and attraction system checkout gear.
This medical Central oxygen-supply and attraction system checkout gear mainly comprise pressure criteria table, back-up valve, take out control valve, effusion meter, first switch, second switch and micro actuator; Described effusion meter is formed a relative closed pipeline jointly with first switch, second switch; Have pipeline to communicate between described pressure criteria table and micro actuator, this pipeline interlinks by back-up valve and pressure source, interlinks with vacuum source by taking out the control valve, and this pipeline interlinks with the relative closed pipeline of effusion meter, first switch and second switch formation again simultaneously.
Medical Central oxygen-supply of this utility model and attraction system checkout gear are at the inconvenience in the existing testing process, a kind of device of developing can be contained this four kinds of checkout equipments, has only an input port, once insert and just can realize pressure, flow detection content, the whole operation process is simple, direct, has saved manpower and materials greatly.It mainly utilizes existing checkout equipment hardware resource, development environment and extensibility, technology by present sophisticated digital display manometer, effusion meter, by designing the gas circuit connected mode voluntarily, finally invented this equipment, traditional complicated problems is simplified.It is as long as a port inserts the numerical measuring that just can realize oxygen pressure, oxygen flow or suction pressure, the flow velocity of bleeding, and it is directly simple that real realization is operated, and saved a large amount of manpower and materials, improved efficient greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Wherein, 1. pressure criteria table, 2. pressure source, 3. vacuum source, 4. back-up valve is 5. taken out the control valve, 6. effusion meter, 7. first switch, 8. second switches, 9. micro actuator.
The specific embodiment
Describe the technical solution of the utility model in detail below in conjunction with drawings and Examples, but protection domain is not by this restriction.
Medical Central oxygen-supply of embodiment and attraction system checkout gear, as shown in Figure 1, comprise pressure criteria table 1, back-up valve 4, take out control valve 5, effusion meter 6, first switch 7, second switch 8, micro actuator 9: described effusion meter 6 and first switch 7, relative closed pipeline of second switch 8 common compositions; Described pressure criteria table 1 has pipeline to communicate with 9 of micro actuators, this pipeline interlinks by back-up valve and pressure source, interlink with vacuum source by taking out control valve 5, this pipeline interlinks with the relative closed pipeline that effusion meter 6, first switch 7 and second switch 8 form again simultaneously.
The work process of above-mentioned medical Central oxygen-supply and attraction system checkout gear is, tested oxygen is after pressure source 2 (or vacuum source 3) inserts, by regulating back-up valve 4 and micro actuator 9 (regulate when vacuum source 3 inserts and take out control valve 5 and micro actuator 9), first switch 7 and second switch 8 are closed, and the numerical value of master gauge 1 demonstration at this moment is oxygen pressure value (or vacuum pressure value).Second switch 8 is opened when measuring oxygen flow, and first switch 7 cuts out, and this moment, the indicating value of effusion meter was the Oxygen Flow value; First switch 7 is opened when flow velocity is bled in measurement equally, and second switch 8 is closed, and this moment, the effusion meter indicating value was the flow speed value of bleeding.
Will be after this checkout gear is succeeded in developing according to the medical central suction of YY/T0186-0187-94 system general technical specifications, medical central oxygen supply system general technical specifications etc. are about the safety indexes to medical Central oxygen-supply, attraction system such as industry standard, national standard and standard, attraction system range of negative pressure, negative pressure air-tightness, alarm device test, the duct end flow velocity of bleeding; Oxygen terminal flow velocity, pipeline withstand voltage test and air-tight test, every indexs such as alarm device test detect.This device has been filled up the blank of medical Central oxygen-supply, attraction system metering context of detection, and carrying out this project detection for quality inspection system provides checkout equipment and technical support.For the sound development that promotes medical and health care system, accelerate the quality inspection career development, improve manufacturing enterprise's measuring means, create bigger social benefit and economic benefit.
