Abstract
The invention relates to a breathing gas gathering device, which comprises a breathing gas buffer. The front end of the breathing gas buffer is connected with a purging hole through a take-off valve. The rear end of the breathing gas buffer is connected with an exhaust pipe. The purging hole is connected with a test terminal and is also connected with an inlet valve. The inlet valve is connected with a cleaning gas. The bottom of the breathing gas buffer is respectively connected with a sampling port and a heater. The sampling port is connected with a gas purifier which is connected with a flowmeter. The heater is connected with a microprocessor controller which is connected with a timer. The flowmeter and the timer are both connected with an air pump which is connected with an air exhaust opening. The invention has the following beneficial effects: the device, which is provided with the breathing gas buffer and the microprocessor controller, has high accuracy, will not bring any agony and malaise to examinees, has a simple structure, is convenient to use, and is very suitable for rapid diagnosis of various diseases.
Description
Technical field
The present invention relates to the breathing gas gathering-device, belong to medical instruments field.
Background technology
Known disclosed a kind of respiration sampling instrument; Comprise a stopple coupon; Said stopple coupon has exhalation vents and gas outlet; It is characterized in that: the exhalation vents of said stopple coupon is provided with a mouth, and the gas channel of said stopple coupon between exhalation vents to gas outlet is provided with and only allows air-flow to flow to first and second retaining valves of gas outlet from exhalation vents, sample is housed between said first and second retaining valves separates device for trapping.During above-mentioned respiration sampling instrument; The person under inspection blows or cough after containing mouth; The air-flow that blows out gets into gas channel after opening first retaining valve; Sample separates the device for trapping separation and holds back liquid phase or the solid phase in the exhaled air flow, discharges after the gas phase that process is separated is opened second retaining valve, and the taking-up sample separates device for trapping and is used for chemically examining.There is a shortcoming in this structure: owing to there is not special gas buffer structure, the gas of collection refluxes easily, and the tidal air that causes collecting is impure, tests wrong.Therefore, need provide a kind of new technology to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of breathing gas gathering-device simple in structure, fast accurate.
The technical solution adopted for the present invention to solve the technical problems is:
The breathing gas gathering-device, it comprises the breathing gas impact damper, said breathing gas impact damper front end is connected with inflatable mouth through delivery valve; Said breathing gas impact damper rear end is connected with gas outlet, and said inflatable mouth is connected with test lead, and said inflatable mouth also is connected with gas admittance valve; Said gas admittance valve is connected with cleaning gas; Said breathing gas impact damper bottom is connected with well heater with sampling port respectively, and said sampling port is connected with gas purifier, and said gas purifier is connected with flowmeter; Said well heater is connected with microprocessor controller; Said microprocessor controller is connected with timer, and said flowmeter all is connected with air pump with timer, and said air pump is connected with exhausr port.
Said microprocessor controller is connected with digital display screen.
The invention has the beneficial effects as follows: this device has breathing gas impact damper and microprocessor controller, and degree of accuracy is high, can not cause any traumatic pain and sense of discomfort to the person under inspection, and it is simple in structure, easy to use, very is fit to the quick diagnosis of various diseases.
