Abstract
The utility model discloses a pulmonary function sensor, which comprises a shell, wherein the lower side of the shell is provided with a blowing nozzle; the left side or the right side of the shell is provided with an air outlet; the upper side of the shell is provided with a plug; a rotor and a stator are arranged in the shell; the rotor is positioned right above the blowing nozzle; and the stator is positioned right above the rotor. During use, the pulmonary function sensor is inserted into a headset jack of a mobile phone through the plug. The working principle is that: a user breathes towards the blowing nozzle, a rotating blade is driven to rotate when air current is blown inwards from the blowing nozzle, electromagnetic induction is generated between the rotating blade and a coil during rotation of the rotating blade since the rotating blade is made of a magnetic material, a current signal is generated in the coil and is transmitted to the mobile phone through the plug, and the mobile phone is used for receiving mic current, filtering, performing frequency spectrum analysis and comparing data input into the mobile phone in advanced, so that the situation of a pulmonary function is obtained. The pulmonary function sensor disclosed by the utility model has the advantages of simple structure, convenience in suing, good use effect, low cost and support of popularization and application.
Description
Technical field
This utility model relates to a kind of lung function sensor.
Background technology
Asthma is chronic respiratory system diseases, and number of patients is numerous, and regular lung function tests has positive role to the formulation of therapeutic scheme.
General lung function sensor on the market, as shown in Figure 3, when air-flow blows, during blade rotation, will cause the break-make of infrared light, according to the frequency of break-make, can calculate intensity and the persistent period of air-flow, and the power of air-flow changes, thereby draw the situation of pulmonary function.But this circuit is comparatively complicated.Volume is larger, and because the signal of its output is count signal.Be not suitable in conjunction with processing platforms such as mobile phones.
The utility model content
For above-mentioned prior art, this utility model provides a kind of lung function sensor.
This utility model is achieved through the following technical solutions:
A kind of lung function sensor comprises shell, and the shell downside is provided with blow gun, and shell left side or right side are provided with the gas outlet, and the shell upside is provided with plug, is provided with rotor and stator in the shell, and rotor is positioned at directly over the blow gun, and stator is positioned at directly over the rotor.
Described rotor is the rotating vane of being made by magnetic material or the rotating vane that is accompanied with magnetic material on it, and the axle of rotating vane is fixing in the enclosure; Described stator is coil, and coil is connected with the plug circuit.
Described plug is the 3.5mm headset plug.
During use, lung function sensor of the present utility model is inserted in the earphone jack of mobile phone by plug, operation principle is: user is exhaled to blow gun, when air-flow is blown into from blow gun, to drive rotating vane rotates, because rotating vane is that magnetic material is made, when it rotates, and produce electromagnetic induction between the coil, generation current signal in the coil, current signal is transferred to mobile phone by plug, and mobile phone is to the reception of mic electric current, filtering and spectrum analysis, and compare with the data of prior implantation mobile phone, thereby draw the situation of pulmonary function.
Used mobile phone is smart mobile phone, and it is provided with plug-in, can carry out filtering and spectrum analysis to the mic electric current, and (function of plug-in is as follows: current signal and persistent period with generation are carried out integral operation to this plug-in, obtain each pulmonary ventilation volume.The ventilation of accumulation continues to be stored by smart mobile phone, and the monthly variation curve, the year that generate Pulmonary Function change curve etc.The eigenvalue of this curve is compared with the pulmonary function eigenvalue of the different morbid state of standard.Get the pulmonary function feature of matching characteristic value the most as monitoring result, and provide corresponding medical advice according to this kind monitoring result to test person.The weather condition that the while smart mobile phone obtains and pollution condition thereof are as the foundation of suggestion) namely can realize by common practise, do not repeat them here.
Lung function sensor of the present utility model, the function of each several part is as follows:
Blow gun: user is blown to sensor by blow gun.
Rotating vane: rotating vane rotates under the driving of air-flow, and it is rotor, upper subsidiary magnetic material or made by magnetic material.
Coil: be stator, when rotating vane rotated, it produced faradic current.
The gas outlet: air-flow blows out from sensors sides, in order to avoid the microphone generating of mobile phone is affected.
Plug: be standard 3.5mm headset plug.
This utility model is transferred to the metrical information of lung function sensor on the mobile phone, and the default routine processes of mobile phone basis is calculated the situation of pulmonary function, and shows at mobile phone screen.If open Telemedicine, the user of service can arrive the tele-medicine platform with the pulmonary function information transmission by mobile phone, and platform will be formulated more efficiently therapeutic scheme according to historical data.
Lung function sensor of the present utility model utilizes mobile phone as the calculate platform of pulmonary function, and its operation result can be sent to the medical monitoring platform, and is simple in structure, easy to use, and result of use is good, and cost is low, can apply.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
A kind of lung function sensor comprises shell 1, as shown in Figure 1, shell 1 downside is provided with blow gun 2, shell 1 left side is provided with gas outlet 3, and shell 1 upside is provided with plug 4, is provided with rotating vane 5 and coil 6 in the shell 1, rotating vane 5 is positioned at directly over the blow gun 2, coil 6 is positioned at directly over the rotating vane 5, and rotating vane 5 is made by magnetic material, and the axle of rotating vane 5 is fixed in the shell 1, coil 6 is fixed in the shell 1, is connected with plug 4 circuit.
Described plug is the 3.5mm headset plug.
During use, lung function sensor 10 of the present utility model is inserted in the earphone jack 9 of mobile phone 7 by plug 4, as shown in Figure 2, operation principle is: user is exhaled to blow gun 2, when air-flow is blown into from blow gun 2, to drive rotating vane 5 rotates, because rotating vane 5 is that magnetic material is made, when it rotates, and produce electromagnetic induction between the coil 6, coil 6 interior generation current signals, current signal is transferred to mobile phone 7 by plug 4, and 7 pairs of mic electric currents of mobile phone receive, filtering and spectrum analysis, and compare with the data of prior implantation mobile phone 7, thereby draw the situation of pulmonary function, shown by display screen 8.
