Background technology
Pulmonary function test is one of important scope of examination of asthma and chronic obstructive pulmonary disease (COPD), for assessing disease
Coincident with severity degree of condition and prognosis, evaluation medicine or other treatment methods curative effect, differentiate expiratory dyspnea the reason for, diagnose lesion
Position, assessment PFT are to the tolerance or labor intensity tolerance of operation and to having important in terms of the monitoring of urgent patient
Directive significance.
Pulmonary function test equipment can carry out pulmonary function test, its predominantly detect project comprising FVC (i.e. forced vital capacity),
FEV1 (i.e. the 1st second lung capacity), FEV1/FVC（I.e. one second rate, lung capacity accounts for the ratio of forced vital capacity within the 1st second）Etc. conventional lung
Functional parameter.
Existing pulmonary function detection instrument and equipment is mainly mechanical detection structurally and mechanically measuring principle, mainly including two
Class, i.e., a kind of is turbine type（Including turbine type and vane type）, one kind is differential.Turbine meter is because of the motion of its impeller
The factor such as inertia and rotating shaft and friction between bearings and journals torque, can influence the precision of measurement, and differential pressure flowmeter is same because sieve
Net obstructs and reduces measurement accuracy, and not easy cleaning, in the course of time, can cause clogging because of filter deposition debris, cause
Evaluated error is increasing.
Chinese invention patent application number 201410441509X, 2014 applyings date September 1 day, discloses entitled：Lung is lived
The patent application of tester, the tester by blow gun toward blow in bucket blow, into the air blowing blown in bucket again by blowing bucket
Gas vent enter connecting tube, the micro-pressure sensor entered by connecting tube in main frame of blowing is detected, and will be detected
Signal is converted into spirometric data, by the spirometric data so as to judge the health condition of people.
There is the tester of many above-mentioned similar principles on the market, in use, needing the blow gun of mouth and tester to keep
Sealing state is simultaneously firmly blown, and a seal cavity is formed between mouth and instrument cylinder, during air blowing, with air in cavity
Increase air blowing resistance can increasing and gas vortex is easily formed in seal cavity, the generation of vortex allows gas to be difficult to reach
The test surfaces of sensor are tested, thus it is relatively elaborate during air blowing, and it is complete to generally require the big air blowing ability of feeling suffocated of repeatedly progress
Into test, particularly with asthma and patients with COPD, it is necessary to which air blowing detection is repeatedly repeated, detection process more wastes time and energy
And data are inaccurate, it is impossible to provide rational basis for estimation for tester's health condition.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings：
It is a specific embodiment of the present utility model as Figure 1-4, including hand-held housing, the hand-held housing includes
One piece of protecgulum 10 and bonnet 11 are mutually fastened on, front and rear covers form internal cavity after fastening, and electricity is internally installed in cavity
Pond 14 and main control board 17, display screen 5 are embedded in the middle part of protecgulum 10, and the bottom of protecgulum 10 sets shift knob 12, rear
Loudspeaker 13 is inlayed in the bottom of lid 11, and the top of hand-held housing connects the bottom of sensor installation seat 1, sensor installation seat 1 and hand
The top for holding housing belongs to and is mutually fastened and connected, the top connection air inlet cylinder of sensor installation seat 1, and the air inlet cylinder is by upper
Lower shell connection is formed, and upper shell 2-1 is square cross section and lower shell 2-2 is circular cross section, is formed between upper lower shell
Taper transition 2-3, blow gun 3 is arranged on upper shell 2-1 top, and upper shell 2-1 belongs to integral structure, lower cylinder with blow gun 3
Body 2-2 bottoms connect the top of sensor installation seat 1, and sensor 4 is set in sensor installation seat 1, and display screen 5, switch are pressed
Button 12 and loudspeaker 13 connect main control board 17 respectively, a pair of exhaust holes 6 in lower shell 2-2 bottoms barrel both sides, pass
Cone-shaped cavity inner wall is set in sensor mounting seat 1, the cone bottom connection lower shell 2-2 of cone-shaped cavity inner wall bottom and its
Sensor 4 is inlayed at vertex of a cone end, and sensor 4 is embedded in its vertex of a cone end by sealing ring 16, in lower shell 2-2 and sensor installation seat
Diversion component is set between 1 cone-shaped cavity, and the diversion component is provided in round deflector 7 and is arranged on sensor installation
In the circular groove of the cone bottom of the cone-shaped cavity inner wall of seat 1, in the centrally disposed blind plate 8 of circular deflector 7, led in circle
Flow on plate 7 and the uniform some small air inlet holes 9 of the surrounding of blind plate 8.
Blow gun 3 is sucked, by blow gun 3 toward air blowing in upper shell 2-1, lower shell 2-2 cross-sectional area is than upper shell 2-1
It is big, this kind design can allow from upper shell 2-1 enter lower shell 2-2 in air-flow more uniformly with air-flow relax, under
Cylinder 2-2 gas is most of to be split discharge from a pair of exhaust holes 6, and remaining portion gas reaches circular deflector 7
Upper surface, due to devising the centrally disposed blind plate 8 in circular deflector 7, therefore the portion gas does not rush at sensor directly
The sensor 4 at the middle part of mounting seat 1, but the uniform some small air inlet holes 9 of the surrounding of blind plate 8 are guided to, and pass through these air inlets
Aperture 9 reaches the cone-shaped cavity inner wall of sensor installation seat 1, therefore the structure of circular deflector 7 is further avoided with shape
The generation of air whirl, gas by the further water conservancy diversion and cushioning effect of cone-shaped cavity inner wall finally reaches sensor
The upper sensing end face of the sensor 4 at the middle part of mounting seat 1, then passed by the mutual signal between sensor 4 and main control board 17
Defeated and calculating, last indices are shown on display screen 5, and the main control board 17 is set to PCB main board；Circle is led simultaneously
The structure of stream plate 7 can also effectively prevent sensing end contact of the foreign matter directly with sensor, different such as the sputum of tester
Thing, protects sensor and extends the service life of sensor.
As can be seen here, tester is when blow test, and whole air blowing process is all divided with gas from exhaust hole 6
Stream discharge allows gas can not produce vortex in the upper test surfaces of inductor, tester blows with being buffered by bullet inwall
Process resistance is small and close to zero resistance, makes test process more light, especially for children or asthma severe patient, Bu Huiyin
Air blowing test of repeatedly feeling suffocated is carried out for the huge resistance of conventional test equipment, it is time saving and energy saving and test data is more accurate.
