The invention relates to a sterile freeze-drying storage device for cytokines. In the prior art, a cytokine product is frozen in a freeze pipe; the freeze pipe is sealed by a sealing film; and then the sealing film is punched manually, so the problems that the cytokine product is contaminated easily and the program is complex are mainly presented. The sterile freeze-drying storage device for the cytokines comprises a pipe cover and a freeze pipe main body connected with the lower end of the pipe cover; the middle part in a cavity in the pipe cover is provided with a sterile screen with the aperture of 0.22 [mu]m; the bottom of the sterile screen is provided with a sterile screen fixing platform; the sterile screen fixing platform is provided with a spiral internal thread; the spiral internal thread is disposed on the lower end of the pipe cover; and a spiral external thread matching with the spiral internal thread is disposed above the freeze pipe main body. The sterile freeze-drying storage device is simple in structure, scientific in design and convenient for use, solves the problem that the cytokines are exposed and contaminated, has a ventilation function, achieves an object of freeze drying during a drying process of the frozen cytokines, and simplifies experimental operation flow.
Description
Technical field
The present invention relates to a kind of medical test equipment, particularly the aseptic freeze-dried save set of a kind of cytokine.
Background technology
Freeze Drying Technique is the dry product freezed under cryogenic vacuum, and dry rear small product size, shape are substantially constant, in spongy, without drying shrinkage; Original proterties can be reduced into rapidly during rehydration.Freeze Drying Technique can remove the moisture of in material more than 90%, dried product long preservative period, and can be placed in preservation process under room temperature and preserve for a long time in lucifuge or 4 DEG C of refrigerators, does not need expensive cryogenic storage facilities and the preservation condition of complexity; And because its very light weight is convenient to long-distance transport in transportation.
Cytokine lyophilize uses freeze drier to carry out, and dried cytokine needs to dress up with permeable container.When pretreatment mode be cytokine product be put in freezing in freeze pipe after, with sealed membrane sealing, afterwards sealed membrane is manually punchinged, to ensure in drying process, the discharge of freeze-drying transpiring moisture.
Therefore following problem can be run in routine experimentation working process:
1, in experimentation, manual seal, the experimentation such as to punching are easy to microbiological contamination, and program is numerous and diverse.
2, cut a hole pore size and can not control, be easy to expose microbiological contamination, and freeze-drying process volatilization is insufficient, affects freeze-drying efficiency.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect how overcoming prior art, there is provided a kind of cytokine aseptic freeze-dried save set, the aseptic freeze-dried save set of this cytokine solves cytokine and exposes microbiological contamination problem, can realize cytokine freeze-drying process and carry out in non-Superclean Lab; There is ventilatory function simultaneously, make the frozen cell factor in drying process, reach cryodesiccated object, simplify experimental implementation flow process, greatly save the time of experimental implementation, and convenient to operation.
For solving the problems of the technologies described above, the aseptic freeze-dried save set of this cytokine, comprise the freeze-drying tube body of low temperature resistant pipe lid and pipe connecting lid lower end, the middle portion of pipe lid internal cavities is provided with aseptic screen cloth that is low temperature resistant, that to provide gnotobasis for the freeze drying cell factor, play ventilation effect simultaneously in the process of cell freeze-drying.
Design like this, solves cytokine and exposes microbiological contamination problem, can realize cytokine freeze-drying process and carry out in non-Superclean Lab; There is ventilatory function simultaneously, make the frozen cell factor in drying process, reach cryodesiccated object.
As optimization, the circular bacterium filter screen of aseptic screen cloth to be aperture be 0.22um.Design like this, can realize the gnotobasis in the process of cell freeze-drying, ventilation effect and effect is better.
As optimization, aseptic screen bottom is provided with aseptic screen cloth stationary platform.Design like this, is convenient to fixing aseptic screen cloth.
As optimization, aseptic screen cloth stationary platform has the spiral internal thread for the aseptic screen cloth of fixing seal and connection freeze-drying tube body, and this spiral internal thread is arranged on the lower end of pipe lid.Design like this, is convenient to the aseptic screen cloth of fixing seal and connection freeze-drying tube body.
As optimization, above freeze-drying tube body, be provided with the outer silk of the spiral matched with spiral internal thread.Design like this, is convenient to pipe connecting lid and freeze-drying tube body and sealing effectiveness is better.
As optimization, aseptic screen cloth outer rim is provided with fixing seal bar.Design like this, sealing effectiveness is better.
As optimization, pipe tops is provided with block.Design like this, sealing effectiveness is better.
As optimization, between block and pipe lid, be provided with hinge and snap close.Design like this, is convenient to fixing block and pipe lid and sealing effectiveness is better.
The aseptic freeze-dried save set of cytokine of the present invention, structure is simple, design science, easy to use, solves cytokine and exposes microbiological contamination problem, can realize cytokine freeze-drying process and carry out in non-Superclean Lab; There is ventilatory function simultaneously, make the frozen cell factor in drying process, reach cryodesiccated object, simplify experimental implementation flow process, greatly save the time of experimental implementation.There is good actual application value and promotional value.
