Abstract
The utility model discloses a kind of sperm swim-up test tube, comprise main test tube (1), it is characterized in that: pipe connecting (2) is arranged on the sidewall of main test tube (1) lower end in 45 ° of angles, point test tube (3) being arranged on pipe connecting (2) upper end is communicated with main test tube (1) by pipe connecting (2).Therefore, the utility model not only has the advantage that structure is simple, cost of manufacture is low, easy to operate, and divide test tube and main test tube to be that 45 ° of angles are arranged, be applicable to sperm swim-up, contribute to being separated energetic and that vigor is weak sperm to greatest extent, the rate of fertilization improving ovum for next step is laid a good groundwork.
Description
Technical field
The utility model relates to a kind of sperm swim-up test tube, belongs to medical equipment technical field.
Background technology
Sperm after sperm swim-up refers to washing puts into capacitation liquid, and the sperm that vigor is good swims over to the process above capacitation liquid.Sperm swim-up has very important effect in being fertilized in vitro, belongs to artificial selection is energetic, quality is high sperm and is used for carrying out in vitro fertilization.Traditional upstream process is: the Sperm pellets after washing is placed in the bottom that capacitation liquid test tube is housed, again test tube is placed on test-tube stand, when sperm swim-up end of processing, test tube is needed to take off from test-tube stand, but test tube rocks the sperm be easy to bottom by the sperm of upstream and test tube a little mixes, because the sperm bottom test tube is the sperm of vigor difference, not only affect the rate of fertilization of ovum, and the super-oxide that the sperm of vigor difference produces can produce detrimentally affect to ovum.
Utility model content
The purpose of this utility model is, provides that a kind of structure is simple, cost of manufacture is low and can by the sperm swim-up test tube of the spermatozoa isolation that in vitro upstream is energetic and bottom vigor is weak, to overcome prior art deficiency.
The technical solution of the utility model: a kind of sperm swim-up test tube, comprises main test tube, pipe connecting is that 45 ° of angles are arranged on the sidewall of main test tube lower end, and point test tube being arranged on pipe connecting upper end is communicated with main test tube by pipe connecting.
Further, pipe connecting is provided with switch-valve, therefore, when sperm swim-up end of processing, switch-valve cuts out, the sperm of main invisible spectro vigor difference so just can be avoided to mix with a point in vitro energetic sperm.
Owing to adopting technique scheme, the utility model has the advantage of: when sperm swim-up, sperm after washing is put into the main test tube that capacitation liquid is housed, because main test tube is vertical placement, sperm is difficult to swim over to above the capacitation liquid of main test tube, sperm can move from the approach of the easy upstream of main separation, and the sperm that namely vigor is good can be swum in point test tube along the pipe connecting arranged in 45 ° of angles; The time of fertilization, closes the switch-valve on pipe connecting, and the sperm of main invisible spectro vigor difference can be avoided to mix with a point invisible spectro energetic sperm, and the capacitation liquid now adopting suction pipe to draw in point test tube is used for fertilization.Therefore, the utility model not only has the advantage that structure is simple, cost of manufacture is low, easy to operate, and divide test tube and main test tube to be that 45 ° of angles are arranged, be applicable to sperm swim-up, contribute to being separated energetic and that vigor is weak sperm to greatest extent, the rate of fertilization improving ovum for next step is laid a good groundwork.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The main test tube of description of reference numerals: 1-, 2-pipe connecting, 3-divides test tube, 4-switch-valve, 5-capacitation liquid, the Sperm pellets after 6-washing.
Embodiment
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The structural representation of sperm swim-up test tube as shown in Figure 1, comprise main test tube 1, pipe connecting 2 is arranged on the sidewall of main test tube 1 lower end in 45 ° of angles, and point test tube 3 being arranged on pipe connecting 2 upper end is communicated with main test tube 1 by pipe connecting 2, and pipe connecting 2 is provided with switch-valve 4.
When sperm swim-up, Sperm pellets 6 after washing is put into the main test tube 1 that capacitation liquid 5 is housed, because main test tube 1 is vertical placement, sperm is difficult to the top swimming over to capacitation liquid 5 in main test tube 1, sperm can move from the approach of the easy upstream of main separation, and the sperm that namely vigor is good can be swum in point test tube 3 along the pipe connecting 2 arranged in 45 ° of angles; The time of fertilization, closes the switch-valve 4 on pipe connecting 2, and the sperm of the vigor difference in main test tube 1 can be avoided to mix with the energetic sperm in point test tube 3, and the capacitation liquid now adopting suction pipe to draw in point test tube 3 is used for fertilization.
Claims (2)
1. a sperm swim-up test tube, comprise main test tube (1), it is characterized in that: pipe connecting (2) is arranged on the sidewall of main test tube (1) lower end in 45 ° of angles, point test tube (3) being arranged on pipe connecting (2) upper end is communicated with main test tube (1) by pipe connecting (2).
2. sperm swim-up test tube according to claim 1, is characterized in that: on pipe connecting (2), be provided with switch-valve (4).
