Technical field
The present invention relates to a kind of U-shaped connected vessels type vital capacity and lung power resists tester.
Background technology
Vital capacity test is one of important test event of human health screening and health check-up, and vital capacity and lung dynamic test can reflect cardio-pulmonary function, and vital capacity and lung power antagonism test can compare the power of antagonist's cardio-pulmonary function, also has stronger recreational.
On market, the existing tester measuring vital capacity and lung power is sold, but do not see special vital capacity and lung power antagonism tester, existing vital capacity and lung Dynamics Tester still have many places not fully up to expectations, the convenient switching of such as lung dynamic test and vital capacity test, instrumentation and internal structure are optimized further and are simplified, improve service life, convenience of reset operation etc., is optimized vital capacity and lung Dynamics Tester and promotes and produce vital capacity and lung power antagonism tester tool significance further.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, provides a kind of simple and reliable for structure, return and function to switch U-shaped connected vessels type vital capacity easily and lung power resists tester.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of U-shaped connected vessels type vital capacity and lung power resist tester, comprise two vital capacity and lung Dynamics Tester, it is characterized in that; Two vital capacity are connected by pipeline with lung Dynamics Tester, pipeline are established a valve also U-shaped linker in parallel, the in-built water of U-shaped linker; Vital capacity and lung Dynamics Tester comprise floating drum and tank, and floating drum is positioned at tank, and floating drum is that top is closed, lower opening formula structure, and tank is integrally closed structure; Bottom of gullet is provided with suction nozzle, and suction nozzle is connected with blowing nozzle through flexible pipe; Be provided with band sealing ring bar cover above tank, band scale float lever inserts in tank from band sealing ring bar cover, and band sealing ring bar inserts in floating drum through float valve seat, and band scale float lever end points is provided with valve plate; Band sealing ring bar and float valve seat junction are provided with spring, and valve plate is due to the elastic force effect compression float valve seat formation sealing of spring; Be provided with air bleeding valve and water feed apparatus above tank, tank side is connected with band scale liquidometer.
Described air bleeding valve comprises handle, cam, bearing pin, valve rod, valve seat and valve plate, and handle connects cam, and cam is through bearing pin connection valve bar, and cam is that axle rotates around valve rod with bearing pin; Be valve seat below cam, valve rod, through valve seat, has passage in valve seat, and stem bottom connects valve plate; Be provided with spring between valve seat and valve plate, holddown spring makes valve seat and valve plate form enclosed construction, and gas can not be discharged from the passage in valve seat, and trip spring makes valve seat and valve plate form Open architecture, and gas is discharged from the passage in valve seat.
The valve plate of described air bleeding valve is provided with sealing ring.
Described tank side is provided with water-level monitoring window, is convenient to observation.
Described bottom of gullet is provided with drain valve, is convenient to draining.
Be provided with cushion pad in described tank, reduce the shock of floating drum and tank.
Vital capacity and lung Dynamics Tester make floating drum float to realize vital capacity to test by air blowing, when carrying out vital capacity test, form oral cavity sealing facing to blowing nozzle to blow, by flexible pipe, gas is imported in floating drum by suction nozzle, valve plate is due to the elastic force effect compression float valve seat formation sealing of spring, floating drum forms airtight cavity, because gas blasts, floating drum is floated, band scale float lever rises in band sealing ring bar cover, the gas flow entered and float lever rising proportion relation, thus realize vital capacity determination.
After vital capacity determination completes, pressing float lever is exhausted return, and spring is compressed, and valve plate departs from valve seat, and gas can discharge floating drum quickly through valve seat, more emptying by air bleeding valve, makes floating drum get back to extreme lower position.
When needs test lung power and lung can export maximum pressure, close air bleeding valve, the gas be blown into is sealed completely by cavity, but water can rise, according to liquidometer liquid level Numerical Implementation lung dynamic test along band scale liquidometer.
Air bleeding valve is for meeting vital capacity test Quick air-discharge action need, realizing required operation readiness with cam mechanism.During exhaust valve opening, cam is in flat condition, and valve plate and valve seat separate by spring, has enough aerofluxus sectional areas to meet the function needs of rapid aerofluxus reset; When needs shutoff operation, pull handle and make cam be in stand up position, actuated by cams Compress Spring is mentioned valve plate simultaneously and is compressed valve seat, relies on sealing ring to realize positiver sealing.
Two vital capacity and lung Dynamics Tester are linked together as representative of the present invention, both can measure vital capacity and lung power in both sides simultaneously, the valve can closing again air bleeding valve and centre carries out vital capacity and lung power antagonism test.U-shaped linker loads water, and both sides antagonist blow simultaneously, the U-shaped higher side of linker liquid level, then this side test person lung power is less, also needs to add sharp movement and just likely again contends with.
Compared with prior art, beneficial effect of the present invention is also:
Apparatus structure simple and durable, reliable; It is reliable that cam realizes opening and closing simple operation; Air-flow inducing QI area is large, is applicable to the rapid aerofluxus under lower pressure; Tensioning is realized and return cost is low with spring; Sealing gasket effectively can prevent Leakage Gas; Vital capacity and lung dynamometry can be carried out, vital capacity and lung power antagonism test can be carried out again, also have stronger recreational, have a extensive future.
