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 cryopreservation tube.
Background technology
Cryopreservation tube is at biology or is medically often used to, for low-temperature storage cell or other material.Cryopreservation tube sealing on market is poor, cause in-built material to be polluted or to reveal, and body easily splits after low temperature.The patent No. is the Chinese invention patent of CN102845414 discloses a kind of cryopreservation tube structure on January 2nd, 2013, comprise body, pipe lid, described pipe lid mounts cover in described body, described pipe lid comprises center circle, surrounding anchor ring, male structure under center, the apical ring structure of the mouth of pipe of described body is flush-mounted in male structure under described center, in the annular gap that surrounding anchor ring is formed, the outer ring surface of the described mouth of pipe is connected with the surrounding anchor ring screw threads for fastening of described pipe lid, it makes not easily to leak under long-term ultralow temperature refrigeration, ensure that cell is not contaminated, ensure normally carrying out of subsequent experimental.But the structure of this evolute also exists its inevitable defect, the pollution source as: evolute easily touch male structure under the center of pipe lid, by pollution source lead-in tube; Evolute be easily trapped in the screw thread place of pipe lid and body junction due to moisture, freeze at low temperatures, increase the difficulty that pipe lid is turned on, have much room for improvement.
Summary of the invention
The object of this invention is to provide a kind of modified node method of cryopreservation tube, its cryovial good airproof performance, be easy to torquing operations, intensity is high, 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 cryopreservation tube, comprise body and Guan Gai, being connected with described body of described pipe lid inner-rotary type, described pipe covers and is provided with external screw thread, the mouth of pipe of described body is provided with internal thread, and described internal thread is for establish internal thread segment jaggy or internal thread point each other.
The present invention adopts the pipe lid of inner-rotary type, solves outward turning easy-to-leak liquid, the defect that pad easily falls, better tightness; 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.
As preferably, described pipe lid is cylindric, comprises hand twist portion and connecting portion by top to bottom, and the external diameter that described hand twists portion is greater than the internal diameter of described connecting portion, twists the formation convergence part, junction of portion and described connecting portion at described hand.
As preferably, described convergence part is provided with mark sealing ring, and the internal diameter of described mark sealing ring is greater than the external diameter of described connecting portion, and the internal diameter of described mark sealing ring is more than or equal to the external diameter that described hand twists portion.
Mark sealing ring is set, can sealing function be played, ensureing the sealing of cryopreservation tube, simultaneously by arranging the sealing ring of different colours, can also mark action be played, easy to use, need not specially go to arrange mark again, save cost and technique.
As preferably, be provided with auxiliary seal ring below described mark sealing ring, the internal diameter of described auxiliary seal ring is identical with described mark sealing ring, and external diameter is greater than the external diameter of described mark sealing ring.
Because cryovial is usually take out from low temperature, mark sealing ring can be adhered to mouth of pipe place, and when turning on pipe lid, mark sealing ring can be driven, its sealing function is affected repeatedly, auxiliary seal ring is set, double shield, and when twisting the lid off, finger props up sealing ring to the hand portion of twisting, prevent from being driven, auxiliary seal ring external diameter is greater than described mark sealing ring, conveniently props up action.
As preferably, form seal groove between the lower surface that the upper surface that described externally threaded top one encloses and described hand twist portion, described sealing ring is arranged in described seal groove.Can enhanced leaktightness circle fixing, strengthen the service life of sealing ring.
As preferably, the width of described seal groove equals the thickness sum of described mark sealing ring and described auxiliary seal ring, can block sealing ring by seal groove, prevents due to turning on of pipe lid and makes it move up and down, affecting its intensity and sealing.
As preferably, described hand twists portion and described connecting portion in cylindrical-shaped structure empty in one, and the bottom of described connecting portion is provided with end face.
The cylindrical-shaped structure of interior sky can save material, reduces costs, the setting of the bottom end face of connecting portion, sealed tube body, also prevents managing interior material and enters in pipe lid, causes waste or pollutes.
As preferably, in the cylindric interior sky that described hand twists portion, be provided with the reinforcement connecting circumference.
Because cryovial is usually take out from low temperature, when turning on pipe lid, need certain dynamics, if power is excessive or the service time of cryopreservation tube is longer, the pipe lid of interior sky is easily bad, and arranging reinforcement can the intensity of reinforced pipe lid, extends its service life.
As preferably, described reinforcement is vertically arranged, and through the center of circle of place, described cylindrical cross section circle, reinforced pipe lid intensity effect is better.
By implementing technique scheme, the present invention has following beneficial effect: cryopreservation tube good sealing effect provided by the invention, and do not affect pouring out of the interior material of pipe, be easy to torquing operations, intensity is high, has group indication function, and save material, cost of manufacture is low.
