Description
Technical field
The utility model is related to respiratory function detection field, more particularly to a kind of portable respiratory function with learning functionality
Detection device.
Background technology
Respiratory function often reflected by lung function, main to measure forced vital capacity FVC, one second expiration amount FEV1 of maximum with
And peak expiratory flow rate PEF.These indexs are usually used in evaluating lung function, differentiate obstructive and restrictive ventilatory functional disturbance.Resistance
Plug property ventilatory dysfunction is mainly shown as FEV1/FVC<0.7, and restrictive ventilatory functional disturbance be then mainly shown as FVC and
FEV1 is simultaneously declined.Since obstructive dysfunction of pulmonary ventilation is different from the cause of disease of restrictive ventilatory functional disturbance, accurately differentiate two
Person helps to treat.Whether patient is can determine additionally by before and after observation movement or using the variation of FEV1 before and after airway constriction medicine
There is airway hyperreactivity, to assisted diagnosis asthma.The size that FEV1 accounts for predicted value is also reflect impairment of pulmonary function degree one
A important indicator.However, lung function it is abnormal except may be due to lung function itself it is abnormal in addition to, it is also possible to due to respiratory muscle work(
It can caused by abnormal.Such as respiratory muscle function decline, diaphragmatic paralysis can cause FVC and FEV1 to decline.In addition, Pulmonary function require by
Examination person's cooperation grasps measurement main points and need to make the actions such as maximum forced suction and forced expiration.However many patients are due to study
Understandability is poor, is ignorant of forced suction and expiration method, causes the numerical value measured low, influences the judgement of result.For example, one by
The FVC of examination person declines, and both may be since lung or respiratory muscle function are abnormal, it is also possible to firmly be exhaled since subject fails to grasp
Main points are inhaled, caused by not maximum to the greatest extent firmly breathing.
Therefore clinically it is badly in need of a device, patient can be helped to grasp respiratory function test main points and differentiate lung work(
It is caused by respiratory muscle function exception or lung exception itself or thorax disease that can decline.

The utility model compared with prior art, has the following advantages that and advantageous effect:
The utility model collection gas flow transducer, carbon dioxide indicator, pressure sensor and respiratory function test main points
Habit is installed on one, easy to carry;Gas flow transducer this index can be further calculated out for detecting air-flow by air-flow
Every lung function index includes FVC, FEV1, FEV1/FVC, PEF (maximum expiratory flow rate), FIVC (forced suction lung capacity).Pressure
The detection of power is the pressure (positive pressure) when allowing subject's forced suction (negative pressure) or forced expiration under duct control system closing.It is above-mentioned
Lung function index and pressure value can be respectively displayed on screen.In addition to helping subject that can obtain maximum forced suction and exhale
Gas, when air-breathing, can hear the sound that the loud speaker under inspiratory flow rate control sent out, make sound intensity with suction using control unit
Gas velocity increases and enhances.Subject is helped to make maximum forced suction by audio feedback.Similar to the above, when expiration, is also audible
The sound that the loud speaker different from when air-breathing to sound quality is sent out, sound intensity also increases with exhalation flow rate and is enhanced, by listening
Feel that feedback helps subject to make maximum forced expiration.Inspiratory phase or expiratory phase is selected to monitor by control unit, help, which is grasped, to be done
The main points of maximum respiratory movement of exerting oneself.
Respiratory function detection device described in the utility model can rapidly help subject's grasp respiratory function test to want
Neck, and can differentiate that decline in pulmonary function is caused by respiratory muscle function exception or lung exception itself or thorax disease, simultaneously
Test result real-time display is being arranged on the display of handle, it is convenient and efficient.
