Description
Technical field
This utility model relates to a kind of integrated sampling reaction unit, particularly relates to the double of a kind of microorganism detection field
Head liquid separatnig valve integrated sampling reaction unit.
Background technology
Clinical medicine microorganism detection field, relates to microbe sampling and detection-phase.Sample should be avoided as far as possible after sampling
Contact stain between product and environment, needs to process sample timely and effectively simultaneously.At present the microbe sampling on clinical medicine and
Process two parts are carried out separately.As a example by bacterial vaginosis detects, first sample with swab during detection, be then placed into
In the pipe of a piece one end open, dripping sample diluting liquid in pipe, extruding tube exterior makes sample discharge from cotton head
Come.Secondly, draw a certain amount of sample liquid handled well with pipettor, add and detect in test strips.This operating process is loaded down with trivial details, will
Sample is exposed in environment process, adds between sample, pollution between sample and environment.Additionally, after swab has taken sample
Need to detect in time, it is impossible to allow sampling swab become dry.Therefore, detection process is exigent ageing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of double end liquid separatnig valve integrated sampling reaction unit, should
Device avoids the pollution between sample and environment, simplifies operating process, and easy to use, range of application is more extensive.
For solving above-mentioned technical problem, adopt the following technical scheme that
A kind of double end liquid separatnig valve integrated sampling reaction unit, including liquid storage pipe, the first liquid separatnig valve, sampling wiper sub bar, anti-
Ying Guan, the second liquid separatnig valve and tail pipe set；First liquid separatnig valve and the second liquid separatnig valve all include valve pocket and broken valve rod；Liquid storage pipe
Inside being inoculated reagent A, load the first liquid separatnig valve, the valve rod of the first liquid separatnig valve is immersed in reagent A, and the valve pocket of the first liquid separatnig valve is even
Connect sampling wiper sub bar；Liquid storage pipe opening part snaps connection at reaction tube one end open, reaction tube other end opening part and tail pipe

Bar stretches in reaction tube, and the swab cotton head of sampling wiper sub bar is positioned at bottom reaction tube.
Being preferably, described sampling wiper sub bar is provided with a hole, after in liquid storage pipe, the valve rod of the first liquid separatnig valve fractures
Liquid flows through sampling wiper sub bar thus hole and flows out, and soaks swab cotton head.
It is preferably, is inoculated reagent A in described liquid storage pipe, loads the first liquid separatnig valve, make reagent A be stored in liquid storage pipe and the
In liquid storage cylinder between one liquid separatnig valve.
Being preferably, can place chemical substance or dry test-paper in described tail pipe set, this chemical substance can be liquid, also
It can be solid.
Compared with prior art, the having the beneficial effects that of this utility model double end liquid separatnig valve integrated sampling reaction unit:
The sampling of sampling wiper sub bar is positioned over the reaction way train of closing after terminating, it is to avoid the pollution between sample and environment；Sampling
Terminating, the snap bar of the liquid storage pipe that fractures, the outer wall of extruding liquid storage pipe, sample treatment solution can be with the sample on sampling wiper sub bar cotton head
This mixing, it is ensured that sample transportation moistens all the time.Meanwhile, sample treatment terminates, and fracture reaction tube tail end the second liquid separatnig valve
Valve rod, removes tail pipe set, extruding reaction pipe outer wall, can drop to detect in test strips, it is not necessary to use pipettor to take out sample
Liquid, simplifies operating process.The effect of tail pipe set is: (1) fractures valve rod in tail pipe overlaps, and prevents liquid splash.(2) extrude
Liquid is as then abandoned in tail pipe overlaps for the incomplete drop of band bubble.(3) use terminates, and puts tail pipe set, makes waste liquid, gives up
Abandon sample preservation in device, it is to avoid pollute environment and operator.(4) tail pipe set may act as the storage chamber of another kind of reagent.Make
Used time fractures the first liquid separatnig valve and the valve rod of the second liquid separatnig valve respectively, discharges the reagent of liquid storage pipe and tail pipe sleeve pipe to instead respectively
In should managing, the example reaction in reaction tube.(5) tail pipe set may act as dry test-paper, chemical substance (solid-state) storage chamber and anti-
Answer room.During use, the solution of biased sample is dropped in tail pipe set, and dry test-paper or chemical substance (solid-state) hybrid reaction,
Observing response result in tail pipe overlaps, this application is applicable to liquid instability but the reagent of solid state stability.This utility model collection sample
Product collection, process and be detected as one, greatly reduce pollution risk, can be widely applied to clinical vaginal, rectum, bottleneck throat sample
Sample detecting reaction and micro-biological samples transport cultivate, be particularly well-suited to bacterial vaginosis detection.
