Description
Technical field
The present invention relates to a kind of lifts to select partial size atomized medicine introducing device.The medical fluid partial size of generation can be selected
It selects, imported into the sample generator in the toxicant exposure cabinet (chamber) of Inhalation as contamination equipment.
Background technique
Toxicity on inhalation experiment is research weight of the chemical toxicant through respiratory tract toxicity on inhalation, toxic action mechanism and control measure etc.
Means are wanted, have been widely used in the fields such as environment, health and medicine at present.It is domestic with the development of international inhalation toxicology
Demand to EXPERIMENT STUDY ON SUBCHRONIC also increasingly increases.Toxicant exposure cabinet for EXPERIMENT STUDY ON SUBCHRONIC is generally divided into dynamic formula and quiet formula two
Kind.Wherein dynamic formula contamination is influenced smaller therefore right due to that can carry out air exchange, contamination process by animal breath and body temperature
Advantage is had more than static exposure.According to current situation, dynamic formula contamination replaces static exposure to have become a kind of trend.
Sample generator is the important component of Inhalation device, and the sample generator of mainstream is solid powder at present
Aerosol generator and liquid aersol generator.Solid and gas aerosols can occur respectively for both generators, still
The particle size that aerosol sample occurs can not be selected.And sample particle diameter of contaminating have to the research of toxicity on inhalation it is important
The sample generating device for influencing, therefore being able to carry out particle size selection necessarily can further push the development of industry.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can be to sample grain
Diameter size carries out the atomized medicine introducing device of selection, and the apparatus structure is simple, easily operated and the features such as be swift in response lift
Select partial size atomized medicine introducing device.
The purpose of the present invention can be achieved through the following technical solutions: a kind of lift selection partial size atomized medicine introducing dress
It sets, which is characterized in that the device includes lift escape pipe, convergence type cyclone separator, venturi spray, air induction conduit, institute
The lift escape pipe lower end stated is equipped with suspended hood, and suspended hood is placed in convergence type cyclone separator, the venturi spray
Convergence type cyclone separator is connected by air induction conduit.
According to the partial size of medical fluid to be sucked, the height of lift escape pipe is adjusted, makes suspended hood lower edge in a certain fixation
The i.e. inhalable partial size of height is no more than the air-flow of setting value.By adjusting liftable discharge pipe, make the suspended hood lower edge of its lower end
On a certain specific floor height, thus after the air-flow for obtaining fixed particle size can import the progress of dynamic inhalation contamination cabinet
Continuous sample toxicity on inhalation contamination.Remaining big drop, which is thrown on wall, to be flowed down, and is discharged through drain pipe.
The adjusting upper height limit of the suspended hood should be lower than air induction conduit mouth at least 3cm, and lower limit should be revolved lower than convergence type
Wind separator reaches the height of maximum gauge.That is suspended hood lower edge height has to be lower than air induction conduit open height, avoids from air inlet
The medical fluid that conduit mouth enters directly is sucked away, and suspended hood lower edge height necessarily is greater than convergence type cyclone separator bottom liquid level
Highly, it avoids the liquid of convergence type cyclone collection sucking suspended hood.
The partial size of the medical fluid to be sucked is monitored by dynamic particle size analyzer.
Medical fluid is formed by spraying by compressed air by venturi spray, enters convergence type cyclonic separation by air induction conduit
Device.
The liftable escape pipe is inserted from convergence type cyclone separator top opening, and in liftable escape pipe
Circle holding and sealing ring are equipped with the junction of convergence type cyclone separator.
The convergence type cyclone separator bottom is equipped with drain pipe and valve, and big drop is thrown on wall and flows down, and passes through
Drain pipe is discharged with valve again through utilizing again in venturi spray jetting device, saves sample size.
The convergence type cyclone separator is in down big up small interior convergent contour, air-flow linear speed during rotation is downward
Degree is continuously increased, successively by smaller and smaller drop separation.The structure of style of introversion cyclone separator is simple, operating flexibility is big, effect
Rate is higher.
Dosage and administration concentration can be obtained by the parameter of air quantity, medical fluid consumption and experiment cabinet.
Compared with prior art, the invention has the following advantages that
1. lift of the present invention selects partial size atomized medicine introducing device, comprising: lift escape pipe (lower end is connected with suspended hood),
Convergence type cyclone separator (has lifting pipe circle holding and sealing ring to guarantee sealing) between separator and escape pipe, venturi spray
Device, air induction conduit, drain pipe and valve.Medical fluid is formed by venturi spray device by spraying, by air induction conduit by compressed air
Into cyclone separator.The separator is in down big up small style of introversion, and air-flow linear velocity during rotation is downward constantly increases
Add, with this by smaller and smaller drop separation, drop is thrown on wall and flows down, and can rejoin medicine by drain pipe discharge
In liquid.At this time by adjusting lift discharge pipe, make its lower end suspended hood lower edge in the i.e. inhalable grain of a certain fixed height
Diameter is no more than the air-flow of a certain value, is conducted into toxicant exposure cabinet and contaminates, so that the partial size to sample selects.The device
Medical fluid is sprayed into cyclone separator by venturi spray device using compressed air.Dosage and administration concentration by air quantity,
The pure consumption of medical fluid (after subduction released liquor) and the parameter of toxicant exposure cabinet obtain.The partial size of medicine drop passes through dynamic partial size spectrometer
It is monitored.
2. the present invention provides a kind of liquid Inhalation sample generating devices that can choose partial size；Structure is simple, easy
In operating, be swift in response.
3. being passed through venturi spray device using compressed air to be atomized medical fluid, to parameters shadow in subsequent toxicant exposure cabinet
Sound is smaller.
