Description
Technical field
The invention belongs to the sprays of the manufacture field of aerosol inhalation administration device more particularly to a kind of aerosol sucking driver
Hole optics batch detection device and method.
Background technique
With being on the rise for air pollution, state, interior foreign aggression respiratory disease patient increasingly increase, respiratory medicine
Also the visual field of medicine enterprise, doctor and patient is progressed into.Asthma (Asthma), chronic obstructive pulmonary disease (Chornic
Obstractive Plumonary Disease, COPD) it is two big diseases in respiratory disease to patient effect's most serious,
World Health Organization's statistical data in 2013 shows that respiratory disease has risen to as the disease of the third-largest high lethality rate, the death rate
Up to 14.09%.However as new technology after Pulmonary inhalation obtains very big development, many patients also more favor in
Pulmonary disease and bronchial disease are treated by the way of inhalation.Recently, from quantitative inhalator (MDI)
Sucking has become the selected path of administration of the other medicines of the non-principal treatment for being related to bronchial disease.Drug is through sucking
Can rapid subsidence in lung, be avoided that or reduce the toxic side effect to other positions；Pulmonary absorption surface area is big, film permeability all
Height, absorption site blood flow is abundant, and drug absorption is rapid；Lung activity ratio is lower, and without liver first-pass effect, these are conducive to
The bioavilability of drug is improved, the local disease that can treat lung can also play the role of systemic therapy.
The inhalator of MDI type generally includes aerosol container, quantitative dose dispensing valve and driver.Driver is logical
Often valve rod and user port including nozzle block, dose dispensing valve.Quantitative dose dispensing valve is inserted into driver, this
When valve rod in conjunction with the nozzle block of driver.When in use, their lip is placed in around mouthpiece and presses aerosol by patient
The bottom of container, so that container is relative to stem movement, to pass through the one drug of mouthpiece small hole injection.If mouthpiece
The circle existing defects problem of jet port, it will cause drug that cannot spray according to the dosage of standard, or the drug sprayed does not have
The problems such as reaching specified patient part, causing the failure of drug, may bring unnecessary influence to patient.And driver
Spout is the miniature aperture of a 0.1-1.0mm, and the detection technique of micropore experienced a long development course.From tradition
Hand dipping, mechanical measurement, gas flow measurement to current optical measurement.Usual researcher uses tool microscope mensuration
Or part detection.Tool microscope is a kind of optical profile type, the high-precision two dimension coordinate measuring apparatus device of multi-parameter, and application range is extremely
Extensively.But desired batch is much not achieved due to the disadvantages of precision, speed, operating method in traditional measuring instrument and method
Testing requirements.The support of accurate detecting instrument, product cannot not detect well, and precision cannot be guaranteed.Modernization
Digital measuring instruments (such as raster pattern universal tool-measuring microscope), although having, measurement accuracy is high, range is big, convenient reading, easily
In the Microcomputer the advantages that, but there are some disadvantages, the disadvantages of such as operation of measurement is difficult, speed is slow, precision is to be improved.It is infusing
During modeling production, it is to differentiate that whether the radius and the round degree of characteristics of aperture, the surface defect problem of aperture and aperture, which are connected,
One of the important parameter of aperture quality.
It in the prior art, is entirely to use the detection method of gas flow to the batch detection of driver spout aperture.
It allows air-flow by aperture, then adds a flowmeter (electronically or mechanically) in the place of gas outflow, read by reading flowmeter
Number extrapolates the aperture of aperture and determines whether aperture is connected.But the detection method can not accurately judge the circle of aperture
The surface defect of degree and aperture, it is also possible to be because the precision of detection device is poor, so as to cause measurement result inaccuracy
Or mistake.If aperture is not that a complete circle or periphery burr occur, may result in drug is not in injection
It is sprayed according to the dosage or direction of defined, influences the Pcnten-1 yne-4 data of drug, drug quality is impacted, it is right
Patient causes different degrees of potential hazard.
In addition existing air-flow batch detection mode, it is desirable to provide more proprietary ancillary equipments such as pneumatic supply increase this
System is to one of the consumption of every resource such as production site, energy and major defect of this method.
Summary of the invention
