Abstract
A freezing pipe conserving sleeve comprises a sleeve with hatch, which is characterized in that a weight is arranged at the bottom of the sleeve with hatch. External threads and a sleeve cap with internal thread are arranged on the upper end of the sleeve with hatch. A hole for feeding liquid ammonia is arranged on the sleeve cap. A flat grip shank with a hole for ropes is arranged on the upper end of the sleeve cap. The utility model has a rational design and convenient operation, which avoids the confusion of freezing pipes on the prior art. The utility model cannot lead to the heating up of all freezing pipes with reliable conservation. The utility model makes the operation in liquid ammonia easy.
Description
Technical field: the utility model belongs to medical supplies, relates to a kind of cryovial and preserves sleeve pipe.
Background technology: cryovial or freezing straw generally all are to preserve in liquid nitrogen, and in the prior art, the mode of preserving in liquid nitrogen mainly contains two kinds, and a kind of is earlier cryovial to be put in the split coupling, is embedded on the casing support, puts into liquid nitrogen then; Another kind is to put into gauze bag earlier, puts into liquid nitrogen then.This dual mode all has certain drawback, the former, split coupling is easy to come off from casing rack, makes the cryovial confusion of preservation; The latter in the time will taking out a cryovial, need propose whole gauze bag, causes whole cryovials to heat up.
Summary of the invention: the purpose of this utility model provides a kind of novel cryovial and preserves sleeve pipe, in order to overcome the above-mentioned defective of existing in prior technology.The purpose of this utility model is to improve realization on the basis of existing technology, it comprises split coupling, its main points are that the bottom of split coupling is provided with weight, the upper end is provided with external screw thread and has the sleeve cap of internal thread, said sleeve cap, have the hole that can enter liquid nitrogen on it, and the upper end has the flat grip shank, the flat grip shank is provided with the tether aperture.During use, on the flat grip shank, mark marks such as name earlier, on the tether aperture, fastened tether, screw off sleeve cap, cryovial to be preserved is packed into, screw sleeve cap again, put into liquid nitrogen container.Or screw off sleeve cap, place the liquid nitrogen dish that is equipped with in addition to lower the temperature earlier split coupling, sleeve cap and cryovial to be preserved, then, with tweezers will be to be preserved in refrigerator tray the cryovial split coupling of packing into, screw sleeve cap, carry tether and from the liquid nitrogen dish, take out, put into liquid nitrogen container again, can realize the freezing preservation of cryovial or freezing straw.
The utility model is reasonable in design, and is easy to use, neither can cause contingent cryovial confusion in the prior art, also can not cause whole cryovials to heat up, and preserves reliably, and is easy to operate in liquid nitrogen.
Description of drawings: Fig. 1 is that master of the present utility model looks cutaway view
Fig. 2 is a side view of the present utility model
The specific embodiment: accompanying drawing has provided an embodiment of the present utility model, with reference to the accompanying drawings, 2 is split couplings among the figure, the bottom of this sleeve pipe is provided with weight 1, and sleeve pipe is sunk in the operation liquid nitrogen, and the upper end is provided with external screw thread and has the sleeve cap 3 of internal thread, said sleeve cap 3, have the hole 4 that can enter liquid nitrogen on it, and the upper end has flat grip shank 5, flat grip shank 5 is provided with tether aperture 6.
For above-mentioned said weight 1 can be recycled, said weight can be one to place the steel ball of sleeve bottom.
Claims (2)
1, a kind of cryovial is preserved sleeve pipe, comprise split coupling (2), the bottom that it is characterized in that this split coupling (2) is provided with weight (1), the upper end is provided with external screw thread and has the sleeve cap (3) of internal thread, said sleeve cap (3), have the hole (4) that can enter liquid nitrogen on it, and the upper end has flat grip shank (5), this flat grip shank (5) is provided with tether aperture (6).
