Description
Technical field
The present invention relates to rubber processings, and in particular to a kind of the pipe lid and pipe lid used in conjunction with of suitable puncture
Adaptive device.
Background technique
Micro centrifugal pipe, also known as EP (eppendorf) pipe, match with micro centrifuge, for trace reagent
Centrifugation and separation.EP pipe had become dedicated generation of the indispensable small size synthetic resin quality tubular container in laboratory and claimed today.Mesh
Preceding common EP pipe has 5ml round bottom centrifuge tube, 2ml scale round bottom centrifuge tube, 1.5ml scale conical centrifuge tube, 0.5ml scale point
Bottom centrifuge tube, 0.5ml thin-walled conical centrifuge tube, 0.2ml scale point bottom flat cover centrifuge tube and the centrifugation of 0.2ml scale point bottom spherical cap
Pipe etc..
In general, managing matching used pipe lid function demand with EP includes: (1) pipe lid and the close fastening of EP pipe.EP Guan Zhongtong
It is often equipped with biological reagent, needs to react (such as needing 95 DEG C of denaturation of experience in PCR reaction process) by high-temperature biological.Pyroreaction
Under, it manages interior gas and expands.Therefore EP pipe pipe lid needs under heating state, and the tolerance bulbs of pressure are without leaking.(2)
It is convenient that pipe lid is opened and closed with EP pipe.User opens pipe lid, and when extracting the biological reagent in EP pipe, required power is small, it is not easy to occur
Biological reagent splash phenomena in EP pipe.(3) using metal, plastic ware or pipe lid adaptive device to EP pipe pipe Gai Jinhang
Puncture, sample it is convenient.It is managed when user pierces through EP using metal, plastic ware (syringe, liquid-transfering gun) or pipe lid adaptive device
Pipe lid extracts the biological reagent in EP pipe, and it is convenient to need to puncture, and air-tightness is good at metal, plastic ware and pipe lid puncture.
Managing matching used pipe lid material with EP at present is the rigid plastics as managing material itself with EP.Plastic conduit
Lid can manage close fastening, tolerance high-temperature biological reaction (such as PCR reaction) with EP.Close button is covered tightly in order to reach EP pipe with EP pipe
The purpose of conjunction, conventional EP pipe nozzle outer are a cyclic structures.But common stereoplasm tube lid the problem is that: (1) pipe lid with
The folding of EP pipe is more difficult.User opens pipe lid, and required power is big, the biological reagent splash phenomena being easy to happen in EP pipe.(2) it uses
Metal, plastic ware puncture EP pipe pipe lid, sample difficulty.Metal, plastic ware pierce through rigid plastics difficulty；Even if wearing
It pierces successfully, air-tightness is bad at metal, plastic ware and pipe lid puncture.
Summary of the invention
For the deficiency of existing pipe lid, the present invention provides a kind of pipe lid, and the pipe lid is integrally formed by rubber material；It is described
Pipe lid includes the upper sealing structure positioned at pipe lid external upper, and the inner wall sealing structure and outer wall inside the pipe lid are close
Seal structure and thin-walled paracentesis area；It is located within region defined by the upper sealing structure with thin-walled paracentesis area upper surface,

The region for being suitable for puncturing being arranged, the pipe lid thickness in the region is smaller than peripheral region thickness under normal circumstances, in pipe Gai Yiti
In molding, cover to form this thin-walled paracentesis area thinner than peripheral thickness in pipe using pipe lid processing mold, be suitable for into
The puncture of the hand-manipulating of needle.Since the pipe lid is made of rubber material, rubber material refers to the strong flexible polymer with reversible deformation
Material, at room temperature high resilience can generate larger deformation under the external force of very little, remove resilient after external force.
After puncture needle punctures thin-walled paracentesis area, it can restore to the original state faster.
In a kind of mode, the pipe lid includes the circumferential closed structure outside pipe lid.
In one embodiment, the rubber material is silicon rubber.Certain rubber material is also possible to natural rubber, closes
At natural rubber, styrene rubber, butadiene rubber, neoprene, butyl rubber, nitrile rubber, the third glue of second, chlorosulfonated polyethylene glue,
Acrylic adhesive, polyurethane rubber, fluorubber, polysulfide rubber, chlorohydrin rubber, epichlorohydrin rubber and chlorinated polyethylene rubber etc..
In a kind of mode, the upper sealing structure is projecting annular structure and/or the institute of the pipe lid external upper
Stating circumferential closed structure is the projecting annular structure around the pipe lid outer lower.
In a kind of mode, the inner wall sealing structure and outer wall sealing structure are carried out with inside pipe wall and pipe outer wall respectively
The cyclic structure of cooperation.
In a kind of mode, the present invention provides a kind of pipe lid arrangement, and the pipe lid arrangement includes above-mentioned multiple pipe lids, described
It is attached between multiple pipe lids by attachment device.
In a kind of mode, the circumferential closed structure of adjacent tubes lid is connected to each other integrally.
In one embodiment, the pipe lid adaptive device include substrate, setting puncture needle on the substrate and
Circumferential seal set.
In one embodiment, the puncture needle is hollow.
In one embodiment, the pipe lid adaptive device is integrated injection molding.
Pipe lid provided by the invention has the advantage that
(1) Guan Gai and the close fastening of pipe, tolerance high-temperature biological reaction (such as PCR reaction).
(2) Guan Gai is opened and closed convenient with pipe.User opens pipe lid, and required power is small, it is not easy to the biological reagent in generator tube
Splash phenomena.
(3) pipe lid is punctured using metal, plastic ware, sample it is convenient.When user uses metal, plastic ware
(syringe, liquid-transfering gun) or pipe lid adaptive device are easy to pierce through pipe lid, facilitate the biological reagent in extraction tube.Metal, modeling
Glassware tool is good with air-tightness at pipe lid puncture.
