Abstract
A kind of novel sperm cryopreservation device being applicable to severe oligospermia, comprise hand lever, support, groove, freezing straw, tampon, adhesive label's paper, described hand lever is located on two symmetrical supports, two symmetrical supports are equipped with groove, freezing straw two ends are arranged in groove symmetrical on two supports, freezing straw one end is provided with tampon, tampon peripheral hardware toughness label paper.The amount of liquid loaded in the every only freezing straw of the utility model is few, and time stifling, liquid is caught a cold evenly, and refrigerating effect is good, easily can find sperm during recovery, and once can fumigate many parts of semen samples, increases work efficiency.
Description
Technical field
The utility model relates to a kind of sperm cryopreservation device being applicable to severe oligospermia.
Background technology
Severe oligospermia refers to sperm concentration < 1 × 10
6/ mL, the sole mode that this type of patient obtains offspring is injection (ICSI) in monosperm ooecium slurry, certain fluctuation is had owing to getting its sperm quality of essence at every turn, probably get ovum its spouse and can not find the capable ICSI operation of enough sperms the same day, even there will be the serious conditions without sperm in the seminal fluid taken out the same day, for avoiding this type of situation to occur, be an effective solution in advance by sperm cryopreservation.The method of this type of sperm freezing mostly is liquid nitrogen fumigating system at present, the steps include: seminal fluid and freezing liquid slowly to mix according to 1:1 volume, is contained in round bottom test tube, is stuck in freezing aluminum frame by round bottom test tube, is positioned over 4c
orefrigerator and cooled is 30min but, then drops into liquid nitrogen container after aluminum frame being put into above liquid nitrogen ware stifling 20min and preserve.The method has following drawback: 1, and mankind's ejaculation volume once is on average about about 2.5mL, adds freezing liquid volume about 5mL altogether, because sperm concentration is very low, is difficult to search out sperm when recovery in so many liquid; 2., because liquid volume in round bottom test tube is comparatively large, be difficult to time stifling liquid is caught a cold evenly, affect refrigerating effect; 3, it is shorter that sperm freezing aluminum frame length is sold in market, and can only place 2-3 round bottom test tube, efficiency is not high at every turn.
Utility model content
The purpose of this utility model in order to overcome deficiency of the prior art, thus provides a kind of novel sperm cryopreservation device being applicable to severe oligospermia.
A kind of novel sperm cryopreservation device being applicable to severe oligospermia, comprise hand lever, support, groove, freezing straw, tampon, adhesive label's paper, described hand lever is located on two symmetrical supports, two symmetrical supports are equipped with groove, freezing straw two ends are arranged in groove symmetrical on two supports, freezing straw one end is provided with tampon, tampon peripheral hardware toughness label paper.
The beneficial effect of employing technique scheme is:
1. the utility model is little due to freezing straw volume, is easier to find sperm at recovery sperm time ratio; Because in freezing straw, liquid is few, (about 0.4mL), when stifling, liquid is caught a cold relatively more even, and refrigerating effect is good; And many parts of semen samples can be fumigated simultaneously, increase efficiency.
2. the amount of liquid loaded in the every only freezing straw of the utility model is few, and time stifling, liquid is caught a cold evenly, and refrigerating effect is good, easily can find sperm during recovery, and once can fumigate many parts of semen samples, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the sperm cryopreservation device structural representation that the utility model is applicable to severe oligospermia.
Fig. 2 is that the utility model is applicable to freezing straw structural representation in the sperm cryopreservation device of severe oligospermia.
In figure: 1-hand lever, 2-support, 3-groove, the freezing straw of 4-, 5-tampon, 6-adhesive label paper.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of novel sperm cryopreservation device being applicable to severe oligospermia, comprise hand lever 1, support 2, groove 3, freezing straw 4, tampon 5, adhesive label's paper 6, described hand lever 1 is located on two symmetrical supports 2, two symmetrical supports 2 are equipped with groove 3, freezing straw 4 two ends are arranged in groove 3 symmetrical on two supports 2, freezing straw 4 one end is provided with tampon 5, tampon 5 peripheral hardware toughness label paper 6.
Described freezing straw 4 capacity is 0.5mL.
This novel sperm cryopreservation device being applicable to severe oligospermia specifically uses step to be:
Seminal fluid is placed in centrifugal 10 minutes of conical pipe (1500 revs/min), abandon supernatant, leave and take precipitation 0.2mL, freezing liquid is pressed 1:1 volume slowly to mix with precipitation, again mixing material is sucked in freezing straw 4, adhesive label's paper 6 marks patient's name and numbering, uses sealing mud to be sealed by freezing straw 4.The freezing straw 4 of sealing is placed in 4c
orefrigerator and cooled is 30min but, is then stuck in groove 3, drops into liquid nitrogen container and preserve after being placed on liquid nitrogen ware stifling 20 min.
Claims (2)
