Description
Technical field
The invention belongs to medical instruments field, relate to a kind of cryopreservation tube, be specifically related to a kind of modified node method of cryovial pipe lid.
Background technology
Cryopreservation tube is a kind of equipment for low-temperature storage cell or other material, comprise pipe lid and body, to have between current body and pipe lid and adopt evolute, also to have and adopt inner-rotary type, respectively there are its pluses and minuses, but no matter be which kind of structure, outside pipe covers and to divide with the screw connection of body and be all exposed to.When getting the material in cryopreservation tube, need operating personnel to be separated with body by the pipe lid of cryopreservation tube, operator not only needs hand-held pipe lid and body, also needs hand-held suction pipe draws substance simultaneously.When especially needing sterile working, more increase the operation easier of operator, the opening portion touching body is easy to when hand-held pipe lid, body and suction pipe while of operator, make sterile working failure, require higher to the operating technology of operating personnel like this, and be exposed to outer screw connection divide be easy to contaminated.The patent No. is the Chinese patent of CN203393147 discloses a kind of cryopreservation tube pipe lid and cryopreservation tube on January 15th, 2014, this pipe lid comprises the housing of hollow, the enclosure interior of described hollow is provided with holly strip, described housing is divided into two parts that one end is closed by described holly strip, described two parts are respectively the first tubular part, second tubular part, described first tubular part and described second tubular part can be connected with a body respectively, when pipe lid connects two bodys simultaneously, when one of them body is used for placing bacterial classification, another body is then equivalent to the length extending traditional pipe lid, when greatly reducing repeat switch pipe lid body to pipette bacterial classification, operator touches the risk of the opening portion of body, facilitate taking for cryopreservation tube in sterile working process.But this cryopreservation tube is two disjunctors always, when only needing use one, causing waste, during making, also wasting material, increasing cost.
Summary of the invention
The object of this invention is to provide a kind of modified node method of cryovial pipe lid, be easy to torquing operations, can effectively reduce pollution probability, intensity is large, and save material, cost of manufacture is low.
In order to achieve the above object; the present invention adopts following technical scheme: a kind of modified node method of cryovial pipe lid; comprise lid and body; described lid comprises hand and twists portion and spiral cover portion; described spiral cover portion comprises outer protective and interiorly screws body; described outer protective and described in screw between body and form body chamber, screw external circle in described and be provided with external screw thread, the mouth of pipe of described body is provided with internal thread.
This technical scheme adopts by outer protective and the interior spiral cover portion screwing body and form, can utilize outer protective play block contaminant fall in screw the effect of body, reduce and pollute probability, adopt the connected mode of inner-rotary type in pipe, sealing effectiveness is better simultaneously.
As preferably, screw in described body is located at and move sap cavity.When needing, may be used for temporarily depositing liquid, easy to use, and again lid upper tube cap time, inside screw body and enter in body, to move on sap cavity residual liquid and fall in pipe, can not drop in outside pipe.
As preferably, the top of described body props up the top in described body chamber.Increase the intensity of cryopreservation tube.
As preferably, be provided with sealing ring between the top of described body and the top in described body chamber, can sealing function be played, ensure the sealing of cryopreservation tube,
As preferably, the top end face in described body chamber is provided with seal groove, and described sealing ring is fixed in described seal groove.During owing to opening pipe lid, often can be with dynamic seal ring, seal groove is set, sealing ring is placed in groove, the fixing of sealing ring can be stepped up.
As preferably, the external diameter that described hand twists portion is less than the external diameter in described spiral cover portion.Twist portion and junction, spiral cover portion forms a hierarchic structure at hand, facilitate torquing operations.
As preferably, the top that described hand twists portion is provided with and identifies and paste groove, can stick different label, play mark action.
As preferably, the described hand portion of twisting is provided with multiple axial fin, increases friction, facilitates torquing operations.
As preferably, described internal thread is for establish internal thread segment jaggy each other.
As preferably, described internal thread is for establish internal thread jaggy point each other.
If adopt traditional inside spin structure, when to the pouring out of liquid feeding in pipe or liquid in pipe, have certain inhibition, liquid in pipe is caused to have residual, impact operation and accuracy, and the internal thread of the mouth of pipe adopts segmentation or dot structure, pouring out of in pipe liquid feeding or liquid in pipe can not be affected.
By implementing technique scheme, the present invention has following beneficial effect: cryopreservation tube pipe lid provided by the invention greatly reduces the probability of pollution, good sealing effect, do not affect pouring out of the interior material of pipe, be easy to torquing operations, intensity is high, save material, cost of manufacture is low.
