Abstract
The utility model discloses a two-step ultra-low temperature hand-operated sperm programmable freezer, which mainly comprises a container. The programmable freezer is characterized in that two groove-shaped guiding columns are arranged on the two sides of the container symmetrically; a sperm sample rack is arranged in the grooves on the inner sides of the guiding columns; a floating barrel is arranged at the lower part of the sample rack; a latticed test tube arrangement rack is arranged above the floating barrel; and two floating barrel columns are arranged on the two sides of the sample rack in the radial direction. The utility model has the characteristics of simple and reasonable structure, smart conception, simple and convenient operation and reliable freezing; the portable two-step hand-operated sperm programmable freezer suitable for laboratories is disclosed for the first time in the country, which provides great convenience for the work of experimenters and effectively solves the problems that the fumigation temperature of liquid nitrogen is difficult to control and people are in danger of being frostbited by the liquid nitrogen when freezing samples are taken out from the liquid nitrogen, so that the utility model has great popularization value.
Description
Technical field
The utility model relates to the medical apparatus technical field, specifically, relates to and a kind ofly is used for human sperm bank or the manual seminal fluid programmed cooling of two-step method ultralow temperature freeze thawing instrument is carried out to seminal fluid in the auxiliary procreation technology laboratory.
Background technology
Two kinds of methods are mainly taked to semen freezing in human sperm bank or auxiliary procreation technology laboratory, manual method and programmed cooling instrument method.The latter costs an arm and a leg, and equipment is from external import, domestic no autonomous production brand.The manual operations method adopts simple and crude metal drum to carry out more, and semen sample is put into metal drum by experience estimation liquid nitrogen plane.Not only the liquid nitrogen fumigation temperature is difficult to control, and has by liquid nitrogen frostbite risk when freezing sample takes out from liquid nitrogen, and misoperation damages the staff easily.At present domestic does not still have be suitable for the manual seminal fluid programmed cooling of breadboard portable two-step method instrument, brought very big inconvenience to experimenter's work.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, and is simple for structure, easy and simple to handle, the manual seminal fluid programmed cooling of freezing reliable two-step method ultralow temperature instrument.
For achieving the above object, the utility model adopts following technical scheme: the manual seminal fluid programmed cooling of a kind of two-step method ultralow temperature instrument, mainly form by a container, it is characterized in that: the guide upright post that is provided with to this container bilateral symmetry two flute profiles, in the guide upright post inner side slot, be provided with the semen sample frame, the bottom of specimen holder is provided with a keg float, and the keg float top is provided with a latticed test tube dispenser, and the radially both sides of specimen holder are provided with two keg float columns.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, have simple for structure, easy and simple to handle, freezing reliable characteristics, openly knowing clearly first at home, this is suitable for the manual seminal fluid programmed cooling of breadboard portable two-step method instrument, bring great convenience for experimenter's work, having solved in the past effectively, the liquid nitrogen fumigation temperature is difficult to control, and when freezing sample takes out from liquid nitrogen, have by the problem of liquid nitrogen frostbite risk, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, the manual seminal fluid programmed cooling of this two-step method ultralow temperature instrument, the bottom is a cylindric cylindrical container 1 that can directly sink to the refrigerated cylinder bottom, be provided with to the bilateral symmetry of this container the guide upright post 2 of two flute profiles, in the guide upright post inner side slot, be provided with the semen sample frame 3 that can slide up and down, the bottom of specimen holder is provided with a keg float 4, and keg float top is provided with a latticed test tube dispenser 5, and the distance to specimen holder remains 50 millimeters in the bottom of keg float.Thereby after whole manual seminal fluid cooling instrument is put into household freezer, cylindrical container can sink in the liquid nitrogen of household freezer, and the semen sample frame makes the semen sample frame remain from the liquid level of liquid nitrogen apart from keeping 50 millimeters under the buoyancy of keg float, accurate temperature when keeping seminal fluid stifling is finished the first step of semen freezing and is fumigated process.Simultaneously above specimen holder, add a top cover 6, can prevent thus when seminal fluid is lowered the temperature, do not make the test tube air-flow when liquid nitrogen gasifies that holds seminal fluid that test tube is gone out specimen holder, and fall in the liquid nitrogen.Make seminal fluid cooling is in the unfavorable environment.Also settled two keg float columns 7 in the radially both sides of semen sample frame, this column can slide up and down in the guide upright post of flute profile.The bottom of semen sample frame column is a keg float, but overcomes the gross weight of floating part according to the floatage energy of keg float, thereby makes the test tube that holds seminal fluid and the liquid nitrogen surface of liquid nitrogen frozen case remain 50 mm distance.As manually most its column of the semen sample frame that can slide up and down being pressurizeed, make the semen sample frame sink to cylindrical container, and with the grooved column with under 8 lockings of locking hand button and the pressurization situation, its interlock keg float is sunk in the cylindrical container of having filled liquid nitrogen together, to cause manual seminal fluid cooling instrument integral body to sink in the liquid nitrogen, finish semen sample freezing second step cooling process in liquid nitrogen.
Claims (3)
