Abstract

The invention discloses a pulmonary function meter, comprising a mobile phone and a pulmonary function sensor, wherein the pulmonary function sensor comprises an outer shell; the lower side of the outer shell is provided with a blowing nozzle; the left side or the right side of the outer shell is provided with an air outlet; the upper side of the outer shell is provided with a plug; a rotor and a stator are arranged in the outer shell; the rotor is located at the right upper part of the blowing nozzle; the stator is located at the right upper part of the rotor; the pulmonary function sensor is connected with a mobile phone circuit through the plug. The working principle is as follows: an user breaths towards the blowing nozzle, the air flow is blown in from the blowing nozzle to drive a rotary blade to rotate; as the rotary blade is made of magnetic materials, when the rotary blade is rotated, an electro-magnetic induction is generated between the rotary blade and a coil, a current signal is generated in the coil; and the current signal is transmitted to the mobile phone through the plug, the microphone (mic) current receiving, wave filtering and spectrum analysis are performed by the mobile phone, and are compared with the data implanted in the mobile phone in advance, thereby the condition of the pulmonary function is obtained. The pulmonary function meter provided by the invention is simple in structure, convenient to use, good in use effect, low in cost, and can be popularized and applied.

Description

technical field [0001] The invention relates to a pulmonary function instrument. Background technique [0002] Asthma is a chronic respiratory disease with a large number of patients. Regular pulmonary function testing plays a positive role in formulating treatment plans. [0003] At present, there are pulmonary function instruments with calculation, storage, and interaction with medical platforms on the market, but they are expensive and cannot be portable and mobile, so they cannot meet the requirements of home monitoring and monitoring anytime, anywhere. It is a good choice to use a mobile phone to implement a lung function test. The mobile phone has a complete wireless interface, and the interaction with the respiratory sensor can be realized by short-distance communication such as Bluetooth and infrared. Interaction with the telemedicine platform can use long-distance communication such as 3G channel, GPRS channel, etc. The mobile phone itself has a good human-compute...
