Description

A kind of Portable lung function detecting instrument
Technical field
The present invention relates to medical treatment detection device technical field, especially a kind of Portable lung function detecting instrument.
Background technique
Chronic Obstructive Pulmonary Disease, abbreviation chronic obstructive pulmonary disease are a kind of common, diseases that can prevent and treat, to continue Respiratory symptom and air-flow are limited as feature, are often as air flue caused by being obviously exposed to toxic granular or gas or alveolar is different Caused by often;Chronic obstructive pulmonary disease is low in China's awareness, and for patient to cognition of diseases deficiency, self-management is poor;China's chronic obstructive pulmonary disease illness rate The 9.9~13.7% of 40 years old or more crowd are accounted for, since its number of patients is numerous, social economical burden weight has become serious danger The important chronic respiratory disease of evil people's health.Sampling Investigation Report is looked back according to national third time is dead: chronic to exhale The desorption system disease males death rate is higher than women, and rural area is apparently higher than city;It is dead that chronic obstructive pulmonary disease accounts for chronic respiratory disease Die rate first place.Patients with COPD needs early intervention, early treatment, and patient answers 1 lung function of conventional every check in 6-12 month, and the state of an illness adds When weight should further consultation at any time, follow-up of patients's time: inpatient usually should after from institute the 2-4 week it is interior to hospital's follow-up, 12-16 Week check lung function, later after 3-6 1 out-patient head of month follow-up are examined should behind 1st month and 2nd month with It visits, it is later primary every 3-6 month follow-ups.Therefore for the detection device of chronic obstructive pulmonary disease illness with regard to particularly important.This detector Abbreviation lung function instrument is detected, what lung functions were mainly relied on is flowmeter, and lung's air-flow point is recorded by flowmeter Analysis.
With the development of science and technology, lung function instrument have passed through following development and update: first generation fluid-type, is done hydrolock Formula drum-type;Second on behalf of vane type or turbine type;Third generation ultrasonic wave, differential, heat-sensitive type have been entered at present.
First generation advantage: it is cheap, it measures relatively accurate;Disadvantage: volume is big, passes through liquid measure volume, it has not been convenient to It carries, can not digitize, pressure is larger, and part lung function deletion patients may be unable to test out accurate pulmonary status.
The shortcomings that second generation vane type or turbine type: due to the motional inertia and shaft of impeller and friction between bearings and journals torque etc. The presence of factor, will affect the precision of sensor, air-flow stop by when turbine can still have inertia rotation that error occurs, and not Energy internal calibration, can not solve.
Third generation ultrasonic type advantage are as follows: non-contact measurement is suitble to the measurement of steady air flow;Disadvantage: for variation The measurement of air-flow is inaccurate, and height above sea level and temperature are affected for gas flow rate, needs to compensate by complicated calculations, low flow velocity Linear response is slightly worse when gasmetry;Differential disadvantage: the heater on flowmeter can be such that capillary network heats, and avoid the full of exhalation Deposition is condensed on sieve-like filter with water vapour, blocks mesh, mostly disposably abandons sensor, with high costs, low flow velocity gas Linear response is slightly worse when bulk measurement.
