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 freeze-dried cytokines, and simplifies experimental operation flow.
Description
Technical field
The utility model 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 that freezes under cryogenic vacuum, dry after small product size, shape substantially constant, be spongy, without drying shrinkage; Can be reduced into rapidly original proterties during rehydration.Freeze Drying Technique can be removed the moisture more than 90% in material, dried product long preservative period, and can be placed under room temperature prolonged preservation in lucifuge or 4 ℃ of refrigerators in the preservation process, do not need expensive low-temperature storage equipment and complicated preservation condition; And in transportation due to its very light weight be convenient to the long-distance transport.
The cytokine lyophilize uses freeze drier to carry out, and the cytokine that is dried need to be dressed up with permeable container.Current processing mode be the cytokine product be put in freezing in freeze pipe after,, with sealed membrane sealing, afterwards sealed membrane is manually punchinged, to guarantee in drying process, the discharging of freeze-drying transpiring moisture.
Therefore can run into following problem in the routine experimentation working process:
1, in experimentation, the experimentation such as manually seal, punching and be easy to microbiological contamination, and program is numerous and diverse.
2, the footpath size of punchinging can not be controlled, and is easy to expose microbiological contamination, and the freeze-drying process volatilization is insufficient, affects freeze-drying efficiency.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, provide a kind of cytokine aseptic freeze-dried save set, the aseptic freeze-dried save set of this cytokine has solved cytokine and has exposed the microbiological contamination problem, can realize that the cytokine freeze-drying process carries out in non-Superclean Lab; Have simultaneously ventilatory function, make the frozen cell factor reach cryodesiccated purpose in drying process, simplified the 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, that the middle portion that the freeze-drying tube body that comprises low temperature resistant pipe lid and pipe connecting lid lower end, pipe cover internal cavities is provided with is low temperature resistant, for the freeze drying cell factor provides gnotobasis, while, play the aseptic screen cloth of ventilation effect in the process of cell freeze-drying.
So design, solved cytokine and exposed the microbiological contamination problem, can realize that the cytokine freeze-drying process carries out in non-Superclean Lab; Have simultaneously ventilatory function, make the frozen cell factor reach cryodesiccated purpose in drying process.
As optimization, aseptic screen cloth is that aperture is the circular bacterium filter screen of 0.22um.So design, can realize that gnotobasis, ventilation effect and the effect in the process of cell freeze-drying is better.
As optimization, aseptic screen bottom is provided with aseptic screen cloth stationary platform.So design, be 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.So design, be convenient to the aseptic screen cloth of fixing seal and connection freeze-drying tube body.
As optimization, freeze-drying tube body top is provided with the outer silk of the spiral that is complementary with the spiral internal thread.So design, be convenient to pipe connecting lid and freeze-drying tube body and sealing effectiveness better.
As optimization, aseptic screen cloth outer rim is provided with the fixing seal bar.So design, sealing effectiveness is better.
As optimization, the pipe tops is provided with block.So design, sealing effectiveness is better.
, as optimization, be provided with hinge and snap close between block and pipe lid.So design, be convenient to fixing block and pipe lid and sealing effectiveness better.
The aseptic freeze-dried save set of the utility model cytokine, simple in structure, design science, easy to use, solved cytokine and exposed the microbiological contamination problem, can realize that the cytokine freeze-drying process carries out in non-Superclean Lab; Have simultaneously ventilatory function, make the frozen cell factor reach cryodesiccated purpose in drying process, simplified the experimental implementation flow process, greatly save the time of experimental implementation.Have actual application value and promotional value preferably.
