Description
Technical field
This utility model relates to chromatographic test paper detection device, a kind of Po Guan mechanism, the sealing test tube assembly including this Po Guan mechanism and application thereof.
Background technology
Charlton is in Sidestream chromatography reagent paper technology (the Lateral Flow of invention in 1988, US6485982) immunology diagnosis revolution has been caused, this diagnostic techniques simplifies sample by the way of chromatographic test paper and adds step, passes through the solid-phase immunity reaction on nitrocellulose filter simultaneously and achieves unprecedented simple, quickly, accurately and inexpensively.Colloidal gold immune chromatography test is generalized to widely used fast medical external diagnosis reagent subsequently, has the most also been generalized to food safety and bio-safety field of fast detection.Other Dry-type biochemical reagent paper also begin to use chromatographic test paper mode simultaneously.In the detection project of these chromatographic test papers, part detectable substance confrontation operator and environment can produce damaging effect, such as anthrax Pathogen test, dioxin etc..The chromatography detecting test paper of the most this kind of detection object needs supporting closed detection device.
The most common chromatographic test paper typically uses hand-held test strips and plastics cartridge two kinds of forms of packaging.The production technology of hand-held test strips is simple, and packaging volume is little, stores convenient transportation.It has only in use by the sample solution of an insertion certain depth of regulation, and solution chromatography the most automatically climbs up test strips, demonstrates result in relatively short period of time.But after having detected, whole test strips being substantially filled with the sample solution of residual, this residual solution may pollute environment and operator in subsequent operation.Main the detecting the urine liking human or animal of immune chromatography test paper of the most currently used hand-held test strips form, has communicable clinical sample and does not the most adopt in this way.
The chromatographic test paper product of plastics cartridge packaging is the main flow of existing market.Typically having three kinds of perforates in plastics cartridge, one is sample viewing window, is used for observing the reaction result of chromatographic test paper；One is sample solution added holes；A kind of is that air-vent is for carrying out the sample solution on rapid draing reagent paper.The sample solution being added on reagent paper may be exposed in atmosphere by these three perforate, may pollute environment and operator.But compare hand-held test strips, greatly reduce opportunities for contamination.
American I nverness company employ a kind of detect urine sample early pregnancy pen type plastics cartridge, the observation window of this kind of cartridge is replaced by LCDs or transparent sealed plastic sheet, the added holes of sample solution is replaced by automatic solution absorbing rod, and after sample solution enters absorbing rod, this absorbing rod can be connected by a plastic sheath set, can be sealed in inside plastics cartridge by sample solution completely.

From Cetus company of U.S. polymerase chain reaction (Polymerase Chain Reaction in 1985, PCR) since realizing the specific amplification of nucleic acid, this technology just because of have high sensitivity, high specific and efficiently feature be widely used in epidemic disease Pathogen test field.But the high concentration cause of disease nucleotide sequence being amplified is easy to contaminated air, test tool and water during subsequent operation, thus results in the false positive results of subsequent detection sample.Therefore in the penetration and promotion of detection of nucleic acids, it is also desirable to develop closed detection apparatus and method.
Solve the nucleic acid amplification product pollution problem when detection, mainly have two kinds of strategies.The first is to build airtight environment during detection nucleic acid amplification product, as: electrophoresis is carried out in airtight negative pressure room, the overall process of real-time fluorescence PCR is not switched on reaction tube, but these methods are required for strict experiment condition and expensive experimental facilities, are not suitable for being popularized for basic unit user.The second is incorporation dUTP in nucleic acid amplification reaction, after react and next time use UNG ferment treatment test tool and environment before nucleic acid amplification, but this method complex operation, and there is certain contamination probability, limit the application of this strategy.
Sidestream chromatography technology is applied in the detection of nucleic acid amplification product by Gerdes etc. (US2004/0110167), brings hope to detection of nucleic acids in basic unit's application.Polluting in order to avoid producing during nucleic acid Sidestream chromatography, optimal selection is to use device to be closed by chromatography process.Look after one's family and forever wait (CN1888902) to invent a kind of closed nucleic acid Sidestream chromatography detection device, its structure includes shell and inner box, inner box includes chromatographing diluent, nucleic acid amplification product and chromatograph test strip, the blade pierces diluted liquid tube in inner box and nucleic acid amplification pipe while shell is closed, the sample pad of chromatograph test strip it is imported into, it is achieved immunochromatography chromogenic reaction after two kinds of liquid mixing.But the shortcoming of this device is: 1, device volume is big, is not suitable for large-scale production and the transport of finished product；2, the test strips in device installs complexity, is not suitable for the reagent paper Assembling Production of scale；3, after this device restarts use, the most simply and can not reopened with having vestige, therefore simply relatively achieve the closing of nucleic acid amplification product, if being not intended to by people open the device reacted, the pollution of amplified production is the most inevitable；4, this device can be only done the detection of single reactant liquor, and multiple reactant liquor cannot be detected, in the way of multiple reactant liquors, i.e. cannot complete the detection of multiple sample in a test strips.
Disclosing a kind of enclosed chromatographic test paper detection device in Chinese invention patent application CN103529201A, this device can realize completely enclosing, and can block the harm to operator of the sample of chromatographic test paper and the pollution of environment completely.But the shortcoming that this device exists has: 1, when solution conduit caliber is less, be difficult to be opened at the bottom of the pipe of solution conduit；2, the gas in connecting tube is not easily accessed solution conduit, causes the gas pressure in connecting tube to raise；If the gas pressure in connecting tube exceedes the air pressure outside pipe, and this pressure differential has exceeded the bearing value sealing structure, and the gas in pipe still can outwards be drained, and when there being solution in pipe, solution also can produce leakage under the driving of gas.
