Description
Technical field
The utility model relates to a kind of apparatus for temporary storage, and in particular to a kind of apparatus for temporary storage for diluting under test gas.
Background technique
There are many pharmaceutical preparations containing gas micro in current field of medicaments.For example, since the end of the sixties
Since Gramiak discovery generates ultrasonography by minute bubbles in liquid (blood), occur various containing gas
The ultrasonic contrast agents of body microballoon, and it is on the books in the literature.
A kind of contrast agent of ultrasound diagnosis, ingredient according to Chinese patent CN 101130094.A include
A kind of protein microsphere formed by protein encapsulation perfluoropropane gas.The rotation that the preparation process of the contrast agent passes through homogenizer
Grinding makes protein encapsulation perfluoropropane gas, and protein microsphere suspension is made, is further dispensed into vial, then gland
It is packaged to be contrast agent finished product.It needs to carry out indices detection after the completion of contrast agent preparation, to guarantee that its quality complies with standard.
Microballoon perfluoropropane gas content detection is exactly an important quality index in contrast agent, and usually used detection method is as follows:
One bottle of contrast agent to be checked is taken to balance to room temperature, then rotation mixes microballoon, pipettes the contrast agent to be checked after certain volume mixes, sets
It is analyzed in vial in 2ml, then the method shaken by physics, rupture the protein microsphere in contrast agent and discharges albumen and is micro-
The perfluoropropane gas wrapped up in ball, it is then (empty with the gas that sampling probe extracts certain volume from analysis vial upper end
The mixed gas of gas and perfluoropropane) with gas chromatograph it is measured containing for contained perfluoropropane gas in the gaseous sample
Amount, so that the content of perfluoropropane in contrast agent be calculated.
By taking above-mentioned perfluoropropane gas as an example, since the perfluoropropane gas content that protein microsphere is wrapped up in contrast agent is non-
It is often low that (contained perfluoropropane gas is usually in volume ratio in the mixed gas of the air and perfluoropropane that obtain after release mixing
Within 5%), often used with perfluoropropane gas in storage container store concentration (usually pure gas, bulk purity are greater than
99.5%) there is biggish gaps.If pure perfluoropropane gas is directly taken to be measured as reference substance, on the one hand, detection
Personnel are difficult with sampling probe and extract minimum gas directly from storage container as reference substance, on the other hand, due in sample
Perfluoropropane gas content is too low, when being detected with gas chromatograph due in reference substance and sample perfluoropropane gas it is dense
It is excessive to spend gap, causes testing result error big, does not have referential.Therefore, it is necessary to pure perfluoropropane gas is diluted,
6 various concentrations (concentration is within volume ratio 5%) perfluoropropane gas reference substance is made, makes microballoon perfluoropropane in sample
Gas content is in standard curve range, and the specific method is as follows: pipetting six differences of perfluoropropane reference substance with sampling probe precision
Micro-scale volume (such as 5 μ l of μ l~100) gas, is injected separately into 2ml Seal analysis vial, after physics shakes, uses
Sampling probe takes gas (mixed gas of air and perfluoropropane) in certain volume analysis vial to be carried out with gas chromatograph
Measurement carries out linear regression to peak area with each perfluoropropane reference substance concentration, linear regression equation is obtained, to be calculated
The content of perfluoropropane gas in contrast agent.However the storage container of pure perfluoropropane gas is usually 2L steel cylinder, due to storage
Container volume is excessive and lacks reasonable sample tap, and trace gas is directly extracted from storage container using sampling probe to testing staff
Body sample causes very big difficulty for further diluting, and the work for extracting minimum gas sample is difficult to realize.

Piercing portion 52, sealing ring 53 and sealing cover housing 51, sealing cover 50 can be reused.
The working principle of apparatus for temporary storage 100 such as following step in the present embodiment:
Step 1, the drain tap and valve 32 of storage container are opened, and the perfluoropropane gas in storage container is led to
Air inlet pipe 20 is crossed to flow into temporary container 10；
Step 2, continue to flow into perfluoropropane gas in temporary container, so that the air in temporary container 10 is passed through row
Tracheae 31 drains into the external world.Testing staff is able to use sampling probe and probes at the circular trough of the outlet of exhaust pipe 31 in the process, can also be with
It is deeper probeed into exhaust pipe 31 using sampling probe, thus the perfluoropropane gas that exhaust gas extraction pipe 31 exports, and pass through detection
The perfluoropropane gas concentration that exhaust pipe 31 exports judges whether the air in temporary container 10 is discharged completely.As detection people
Member judges to keep in the drain tap and valve 32 that storage container is then closed after the air in container 10 is discharged completely；
Step 3, testing staff is needled into the portion 52 that is needled into sealing cover 50 using sampling and extracts perfluoropropane gas, will
The perfluoropropane gas of extraction is squeezed into the sampling bottle of the predetermined volume of dilution, to complete to dilute.By the perfluor after dilution
Propane gas carries out Concentration Testing as standard items, with the perfluoropropane gas sample of required detection.In detection process if there is
It needs, testing staff can also be used for multiple times sampling probe and extract perfluoropropane gas.
Testing staff can be according to the service condition in the portion that is needled into 52 to determine whether needing to replace sealing cover 50.If detection
Personnel's judgement needs to replace sealing cover 50, and after the completion of replacement, which can continue to work normally.
Embodiment action and effect
The apparatus for temporary storage of the perfluoropropane gas according to involved in the present embodiment, air inlet pipe include the air inlet being sequentially communicated
Connecting tube and air inlet snorkel, since one end of the air inlet pipe is inserted into the air inlet that temporary container is equipped with and the other end connects
It is connected to the outlet of perfluoropropane gas on storage container, therefore perfluoropropane gas can be flowed from storage container by air inlet pipe
Enter in temporary container；Since one end of exhaust pipe is inserted into the gas vent that temporary container is equipped with and the other end and temporary container
Extraneous connection, therefore original air can be expelled to the external world of temporary container by exhaust pipe in temporary container, to reach
The effect of temporary perfluoropropane gas has been arrived, the volume of temporary container when testing staff's sampling is effectively reduced, wherein due to
Valve is installed on exhaust pipe, therefore plays the role of the flow that the air of temporary container is discharged in control.
In the sample tap being equipped with due to the temporary container of sampling connecting tube one end insertion and the other end is mounted with to be equipped with needle
The sealing cover in piercing portion, therefore testing staff is able to use sampling and is needled into the portion of being needled into acquirement under test gas, wherein due to
The sealing cover is detachably arranged in sampling connecting tube and is needled into portion and can be used for multiple times, therefore testing staff can be more than enough
It is secondary to be needled into portion's extraction under test gas using sampling or replace sealing cover as needed.
