At medical instruments field, lung function equipment is used in many pulmonary function test projects in a large number; Wherein, lung function equipment (being existing lung function instrument) can carry out pulmonary function test (pft) and follow the trail of lung health situation, can measure conventional lung function parameters such as comprising FVC (being forced vital capacity), FEV1 (first second vital capacity), FEV1/FVC (one second rate, first second vital capacity accounts for the ratio of forced vital capacity).
What but existing lung function equipment was mainly used is mechanical detection structure and mechanical measurement principle, mainly comprise the lung function that two types of detection architecture realize, be to be a kind ofly that turbine rotation detects (for example vane type and turbine type lung function equipment), another kind be differential detection (for example: differential pressure flowmeter);
Wherein, vane type and turbine meter (Vortex shedding).The characteristic being directly proportional to fluid velocity according to the velocity of rotation of rotatable parts (impeller or turbine) is measured.Air-flow by time promote impeller or turbine rotation, vane type adopts photoelectricity to adjust modulation principle, by photoelectric effect, turbine type adopts magnetoelectricity modulation principle, by magnetoelectric effect, the mechanical rotation signal of impeller or turbine is converted to signal of telecommunication output.Due to motional inertia and the factor such as rotating shaft and friction between bearings and journals moment of impeller, can affect the precision of sensor.And most importantly, it is also not suitable for the heavier patient of the state of an illness and detects measurement, because above-mentioned patient's respiratory function has become very weak, brings like this accuracy of detection error inevitable very large, even patient is unable blows to obtain moving vane rotary, causes cannot obtaining detecting data.
Wherein, differential pressure flowmeter (pressure differential flowmeter): utilize the drop of pressure of air-flow and the dependence of flow velocity mensuration flow in the circulation duct of definite shape.Pressure difference sensor comprises two parts: flow transducer: realize the linear transformation of gas flow rate and pressure reduction, according to the air velocity of this changer of flowing through, vary in size, changer two ends sensitivity goes out corresponding pressure differential, i.e. pressure difference signal.Differential pressure pickup: convert the pressure difference signal with flow proportion relation to the certain signal of telecommunication, show with numeral or curvilinear figure after treatment.On the flow sensor of this effusion meter, there is a sieve shape filter, the resistance that air-flow is netted during by this net and flow velocity declines, result slightly declines the pressure of the other end of mesh.Mesh two ends form pressure drop difference.Differential pressure pickup pressure reduction induction accordingly, produces the signal of telecommunication.Flow velocity is faster, and pressure drop is larger, produces the pressure reduction signal of telecommunication stronger.But above-mentioned filter easily deposits harmful substances indication, mesh stops up and antibacterial, and above-mentioned differential lung function equipment cleaning sterilization is difficulty comparatively, and such mechanical detection method is also very large at high flow capacity mensuration time error in addition.
In the prior art, released again subsequently a kind of pulmonary function instrument that utilizes ultrasound examination, this pulmonary function instrument is built-in with disposable ultrasonic corrugated hose, and also include and control mainboard and liquid crystal display, wherein:
Disposable ultrasonic corrugated hose is main pipeline; The top sidewall of main pipeline and bottom sidewall upper top window and bottom windows; Also comprise the pipeline vertical with main pipeline, be provided with two ultrasonic sensors in this vertical pipe, the operation principle of these two sensors is:
The difference △ t=(t1-t2) that controls mainboard Preset Time passes through the proportional relationship numerical value of gas flow value with main pipeline; In corrugated hose structure in the prior art, referring to Fig. 1, wherein two ultrasonic sensors are launched ultrasonic testing signals relatively; Wherein a ultrasonic sensor A, calculates its inner receiving system reception sources from the time t1 of its inner discharger transmitting detection signal; Another ultrasonic sensor B, calculates the time t2 that its built-in receiving system receives the discharger transmitting detection signal of internally-originated; Carry out gas flow value while detecting operation at every turn, control the difference △ t that mainboard calculates the time of current detection operation, and obtain current detection operation by the gas flow value of main pipeline by described proportional relationship numerical solution.By above-mentioned ultrasonic detection method and structure, can realize high-precision detection like this; But it also has certain defect, because said structure is all built in host shell, so the size of each structure member of its inside all restricted (restriction of size characteristic, in order to realize the portable function of above-mentioned instrument and equipment); For example: the inwall caliber of main pipeline can not be too large; But the words that main pipeline inwall caliber is too little, in addition, the frequency that at every turn sends detection signal due to ultrasonic sensor is 100 to 200 times per minute, control the calculating of mainboard and the precision of computing too little relevant with its main pipeline inwall caliber, distance its testing result far away (precision calculating) that in main pipeline usually, ultrasound examination is propagated is also just more accurate; But main pipeline inwall caliber can not arbitrarily increase; Therefore how further to promote accuracy of detection very important.

The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings this utility model is described in further detail.
Referring to Fig. 2, this utility model embodiment provides disposable ultrasound wave corrugated hose, comprises and controls mainboard (not shown), also comprises main pipeline 1 and the liquid crystal display (not shown) of tubular;
The top sidewall of main pipeline 1 and bottom sidewall upper top window 10 and bottom windows 11, top window 10 is relative with bottom windows 11 is certain tilt angle alpha setting;
Respectively there is a thin slice at top window 10 and bottom windows 11 places, and for sealing above-mentioned window, (this thin slice can seal above-mentioned window, leakage air not, but can filter ultrasound wave, the structure that in Fig. 2, dash area is illustrated is thin slice), the thin slice outside that is positioned at top window 10 places is also provided with the first pipeline 12 according to the bearing of trend of tilt angle alpha; The thin slice outside that is positioned at bottom windows 11 places is also provided with second pipe 13 according to the bearing of trend of tilt angle alpha; In the first pipeline 12 and second pipe 13, be provided with the first ultrasonic sensor 14 and the second ultrasonic sensor 15; Controlling mainboard is electrically connected to liquid crystal display and the first ultrasonic sensor and the second ultrasonic sensor respectively;
Wherein, the first ultrasonic sensor 14 comprises the first discharger 140 and first receiving device 141; The second ultrasonic sensor 15 comprises the second discharger 150 and the second receiving system 151; The end that the first discharger 140 on the first ultrasonic sensor 14 and first receiving device 141 are arranged on respectively the first pipeline 12 and the end of second pipe 13, the first discharger 140 institute relative with first receiving device 141 at an angle, and equals above-mentioned tilt angle alpha; The second discharger 150 on the second ultrasonic sensor 15 and the second receiving system 151 are arranged on respectively the end of second pipe 13 and the end of the first pipeline 12; The second discharger 150 institute relative with the second receiving system 151 at an angle, and equals above-mentioned tilt angle alpha;
Wherein, in this utility model embodiment, according to the operation principle of two pairs of ultrasonic sensors in two couples of ultrasound examination principle analysis this utility model embodiment in prior art, analyze known: the first discharger 140 on the first ultrasonic sensor 14 and the relative transmitting of the second discharger 150 ultrasonic testing signals on the second ultrasonic sensor 15; The first ultrasonic sensor, for calculating first receiving device 141 reception sources from the time t1 of the first discharger 140 transmitting detection signals; The second ultrasonic sensor, for calculating the second receiving system 151 reception sources from the time t2 of the second discharger 150 transmitting detection signals;
The difference △ t=(t1-t2) that controls in the prior art mainboard Preset Time passes through the proportional relationship numerical value of gas flow value with main pipeline; Carry out gas flow value while detecting operation at every turn, calculate the difference △ t of the time of current detection operation, and obtain current detection operation by the gas flow value of main pipeline by proportional relationship numerical solution.The principle of ultrasonic flow transducer: two pairs of hyperacoustic dischargers and receiving system are placed in the both sides at corrugated hose, because ultrasound wave must be propagated by medium (being air), propagating the required time depends on that (and the distance between first sensor and the second sensor determines propagation distance, for example: main pipeline inwall pipe diameter size; Therefore, be necessary to limit, the diameter of inner pipe d scope of above-mentioned main pipeline 1 is 15mm-25mm.), be respectively t1 and t2 (seeing Fig. 2).When flow is zero, t1=t2, so △ t=(t1-t2)=0;
Yet in this utility model embodiment, above-mentioned top window is chosen for 40-50 degree with the relative range of tilt angles of above-mentioned bottom windows.This angle of inclination is conducive to the prolongation of above-mentioned propagation distance, due to the prolongation of the propagation distance of two ultrasonic sensors, has also increased the accuracy of detection of ultrasound examination.Because the tranmitting frequency of ultrasonic sensor is approximately 100 detection signals of transmitting per minute (being to export flow signal each second 100 times), be the detection data of sound wave many times the detection time that its ultrasonic sensor obtains like this, then the result that final conversion obtains, such testing result has very high accuracy of detection, ultrasonic signal is different from mechanical detection simultaneously, its accuracy of detection can (not comprise installation rigging error because of machine error as any mechanical mechanism of the prior art, machining error etc.) affect accuracy of detection, can because of patient's respiratory function, not decline and affect accuracy of detection yet, because its pulmonary function flow detection does not need to rely on any mechanical mechanism to realize.Particularly, as air-flow (Gasflow, be the gas flow direction that in Fig. 2, G illustrates) when the main pipeline, propagate and accelerate with air-flow ultrasonic testing signals in the same way, and propagate with the reverse ultrasonic testing signals of air-flow, slow down, so the size relation in direct ratio of the difference △ t of time and gas flow value.Because time difference △ t is exactly that flow causes, so we have just directly measured respiratory flow, do not need calibration to proofread and correct, there is not conventional flow quantity sensor non-linear distortion and measuring range restriction etc. problem yet, very faint or very large flow can be measured accurately, is best, the most accurate flow transducer of performance.
You need to add is that, place two pairs of ultrasonic emitting and receiving system in the both sides of main pipeline, because ultrasound wave must be propagated by medium (being air), propagating the required time depends on propagation distance (size of caliber in main pipeline).Therefore, the diameter of inner pipe of main pipeline has determined that the size of proportional relationship numerical value is (for integrated design, the inside/outside diameter size of main pipeline can not be too large), usually, when the diameter of inner pipe of the main pipeline of disposable ultrasound wave corrugated hose determine and two pairs of sensors between propagation distance determine after, above-mentioned proportional relationship numerical value will be definite value; By above-mentioned relation formula and definite value, just can solve each time gas flow value to be detected.Above-mentioned top window is relative with bottom windows and be angle of inclination and arrange, in order increase to detect to a certain extent duration (inclination than vertical placement time discharger larger with the transmitting receiving range of receiving system), to be also convenient to booster accuracy of detection by the increase of detection distance like this.
Wherein, referring to Fig. 4 and Fig. 5, one end of the main pipeline 1 of described tubular is horn-like inlet tube portion 101, and the other end is the straight tube pipe portion 102 of sealing outlet; The head of described horn-like inlet tube portion 101 is elliptical openings C.
According to oval-shaped shape definition: the track that ellipse is is the point of normal value to the distance sum of two fixed points in plane; Because, in plane with the distance of two fixed point F1, F2 and equal constant 2a (2a > | the track of moving some P F1F2|) is called ellipse.That is: | PF1|+|PF2|=2a;
Wherein two fixed point F1, F2 are called oval focus, the distance of bifocal | and F1F2|=2c<2a is called oval focal length.P is oval moving point.The string of the straight line gained that elliptical cross section overlaps with bifocal line is major axis, and long is 2a; The straight line gained string that elliptical cross section is vertically divided bifocal line equally is minor axis, and long is 2a;
Through measuring, in the embodiment of the present invention, the head of horn-like inlet tube portion is that the size characteristic of elliptical openings C is as follows: oval focal length is 2c=20mm, long axis length 2a=36mm, minor axis length 2b=30mm.It should be noted that, above-mentioned oval-shaped open design is to be for integral body common in prior art the technological improvement that the corrugated hose of straight tube is done, and the shape of above-mentioned elliptical openings is for meeting the shape of the mouth as one speaks shape of human body; The size characteristic of above-mentioned elliptical openings is for adapting to the size characteristic of the human body shape of the mouth as one speaks, and this technical characterictic can promote user's Experience Degree, meanwhile, produces gas leak phenomenon while preventing from testing; Also can find out that thus (diameter dimension only has 15-25mm under the size condition by limited for the main pipeline of the tubular of disposable ultrasound wave corrugated hose in the embodiment of the present invention, very little), also how can to find out by rational architecture advances, strengthen the difficulty of its accuracy of detection.
Preferably, described thin slice is for top window and the air seal of bottom windows place and can passes through the diaphragm of hyperacoustic signal wave.
It should be noted that, above-mentioned diaphragm can have certain sealing property, guarantees not leak by the gas of main pipeline, and this diaphragm can also pass through hyperacoustic signal wave, and gas is had to filter action.
