Abstract
The utility model belongs to medical field, specific pipe is deposited to closed aseptic freezing that says so. Including body and tube cap, the tube cap is located the body top, be the outside of tubes chamber in the body, the top in outside of tubes chamber is the outside of tubes mouth, be provided with intraductal chamber in the outside of tubes chamber, the top in intraductal chamber is intraductal mouthful, the intraductal mouthful level who goes up the edge is higher than the level on edge on the outside of tubes mouth, intraductal mouthful wholly is anti - funnel structure. The utility model discloses a during the intraductal mouthful back of sealing, liquid nitrogen can not get into and freeze the intraductal chamber of depositing the lumen, can effectively avoid the cross contamination of biological specimens liquid nitrogen in preserving to sealed convenient operation. Because the bottom sets up to the toper structure, so directly arranging the centrifugal separator in, the convenience carries out centrifugal operation.
Description
Technical field
The utility model belongs to medical field, specifically a kind of closed aseptic cryopreservation tube.
Background technology
The cryopreservation tube used in liquid nitrogen is at present used alone inward turning or outward turning bottle cap closes the mouth of pipe, though can not overflow under its content freezing state can be ensured, but liquid nitrogen cannot be stoped to flow in cryopreservation tube, may there is cross pollution in the pathogene of carrying in freezing sample in liquid nitrogen.
Existing patent such as number of patent application is CN201420189931.6, the day for announcing is 2014-10-22, name is called the utility model patent of " a kind of novel cell cryopreservation tube ", its technical scheme is: comprise body and block, the groove tube that described body comprises straight tube and is connected with straight tube lower end, the upper end of described straight tube connects block; Described groove tube comprises vertical wall section and circular arc wall portion, and the circular arc wall portion of this groove tube and the angle α of vertical wall section are 100-170 °, and the wall thickness of described groove tube is 0.6-1.5mm.Although above-mentioned patent can be avoided being rinsed when rinsing, and does not affect and again dispel cell after rinsing, still there is the problem that cross pollution may occur the pathogene of carrying in freezing sample in liquid nitrogen in its structure.
Utility model content
In order to improve the sealing property of cryovial, avoiding the flowing of liquid nitrogen inside and outside cryopreservation tube, thus preventing the cross pollution between frozen sample, a kind of closed aseptic cryopreservation tube of existing special proposition.
For realizing above-mentioned technique effect, technical solutions of the utility model are as follows:
A kind of closed aseptic cryopreservation tube, it is characterized in that: comprise body and Guan Gai, described pipe lid is positioned at above body, be pipe exocoel in described body, the top of described pipe exocoel is pipe collar extension, is provided with tube cavity in described pipe exocoel, and the top of described tube cavity is pipe internal orifice, on described pipe internal orifice, the level height on edge is higher than the level height on edge on pipe collar extension, and described pipe internal orifice entirety is in anti-funnel structure.
Pyramidal structure is set at the bottom of the pipe of described body.
Caliber at the bottom of the pipe of described body diminishes from top to bottom gradually.
The density of described pipe internal orifice is lower than the density of body.
The opening size of described pipe internal orifice is less than the opening size of pipe collar extension.
For being threaded between described Guan Gai and pipe collar extension.
Also be provided with base outward at the bottom of the pipe of described body, described chassis interior is provided with the fixed groove with form fit at the bottom of pipe, is also provided with cross fixed mount in described fixed groove.
The utility model has the advantage of:
1, after pipe Closing of internal opening of the present utility model, liquid nitrogen can not enter in the tube cavity of frozen tube chamber, effectively can avoid the cross pollution in biological sample Liquid nitrogen storage, and seal operation is convenient.
2, the utility model is set to pyramidal structure due to bottom, is directly placed in centrifuge carries out centrifugally operated so convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is base vertical view.
In accompanying drawing: body 1, pipe lid 2, pipe exocoel 3, pipe collar extension 4, tube cavity 5, pipe internal orifice 6, at the bottom of pipe 7, base 8, cross fixed mount 9.
