Description
Technical field
The utility model patent belongs to biomedicine field, is specifically related to a kind ofly be specifically designed to storage, process and the novel agent pipe of transfer liquid reagent or sample.
Background technology
In biologic medical field, liquid reagent or sample often need to store, process and shift the suitable container of needs, and this container application scope is comparatively wide, and demand is comparatively large, particularly research laboratory and hospital.The Reagent Tube that container is in the market mainly all kinds of, can be divided into two classes according to the mode of uncapping of reagent bottleneck: a class is flip-shell Reagent Tube, mainly utilizes finger upwards open or cover Reagent Tube downwards; Another kind of is screw-on Reagent Tube, mainly utilizes finger to carry out spiral rotary clockwise or counterclockwise and turns on and open or cover Reagent Tube.
Flip-shell Reagent Tube structure is simple, and pipe lid and body are connected in one, manufacture easy to process; Use easy and simple to handle, only need manually to renovate pipe lid on body, the unlatching of Reagent Tube can be realized or cover, this especially in some cases, operating personnel only need singlehanded just can carry out opening or covering Reagent Tube.Covering of flip-shell Reagent Tube mainly relies on the mutual elasticity of the oral area of pipe lid and body to extrude, but when Reagent Tube is standing to be inverted in concussion operation or transportation, to roll and collision, elasticity extruding can make Reagent Tube generator tube lid collapse situation about holding; And after repeatedly renovating, between Reagent Tube pipe lid and body oral area after frequent wear, easily there will be and cover not tight situation.This above-mentioned situation all can cause spilling of reagent liquid in pipe, causes the waste of reagent or the pollution of sample.
Screw-on Reagent Tube is generally comprise pipe lid and body, is not directly connected as a single entity between pipe lid and body, covers all arrange matching thread at body and pipe, manually screws pipe lid and can realize the unlatching of Reagent Tube or cover.Screw-on Reagent Tube can solve flip-shell Reagent Tube effectively can collapse suddenly the problem held, and crimp when screw-on is dependence screwed simultaneously between material carrys out the sealing of guarantee reagent pipe, avoids the problem of meeting frequent wear.Screw Reagent Tube to need when adding and get reagent at every turn to open pipe lid, but when needing Reagent Tube quantity to be processed larger, need the pipe lid opening more number, pipe lid is also needed to cover one by one on the body of correspondence after using, workload is heavy completely, is also easy to the situation of generator tube lid and body lid mistake simultaneously.
Summary of the invention
The purpose of this utility model realizes like this.
A kind of Reagent Tube, it is characterized in that: be made up of body, pipe lid and outer tube lid, the top of described body is provided with pipe lid, and the top of pipe lid is provided with outer tube lid; Body has the end in vain in being cylindrical without what push up, and the external cylindrical surface of body is provided with mark and graduation mark, the upper end of body is the mouth of pipe, the external cylindrical surface of the mouth of pipe is provided with external screw thread A; Described pipe lid is that hollow is without pushing up bottomless multidiameter, its large end is lower nozzle, lower nozzle inwall there is internal thread A, internal thread A and external screw thread A is connected, lower nozzle can be divided into skin, internal layer from outside to inside, outer field external cylindrical surface is provided with annular knurl, and form two tapered region of a positive and a negative between the outer medial surface of pipe lid and internal layer lateral surface, its one-sided longitudinal cross-section is ∑ shape; The small end of pipe lid is upper orifice, upper orifice external cylindrical surface is provided with external screw thread B, is provided with shoulder hole in pipe lid, and the top of shoulder hole is provided with aluminium film A, and the step surface of shoulder hole is the top of internal layer.
The top of described internal layer is provided with one deck aluminium film B, is filled with filter core between aluminium film B and aluminium film A.
Described outer tube lid has top in vain in being bottomless cylindrical, and the lower end of outer tube lid is the mouth of pipe, internal thread B on internal wall of pipe orifice, and the top of outer tube lid is provided with sealing ring, and the external cylindrical surface of outer tube lid is provided with annular knurl.
Described outer tube covers after Guan Gai carries out puncture sampling, and the internal thread B of outer tube lid and the external screw thread B of pipe lid is connected.
The concrete following advantage of the utility model:
1), the structure of Reagent Tube is simple, easy for operation, reliability is high, anti fouling performance good, is namely applicable to manual operations, can meet again the instructions for use of self-reacting device;
