Abstract
The utility model relates to a sperm swimming-up pipe which comprises a swimming-up pipe 1 and a container cover 3, wherein the sperm swimming-up pipe 1 is internally provided with an arc-shaped baffle plate 6 which divides the sperm swimming-up pipe 1 into a small pipe cavity 5 and a big pipe cavity 4. The bottom of the small pipe cavity 5 is provided with a hole communicated with the big pipe cavity 4. After sperms are eccentrically washed, sperm sediment is absorbed by a dropper and then the dropper is inserted at the bottom of the small pipe cavity 5 to blow the sperm sediment out, and the sperm sediment flows from the hole at the bottom of the small pipe cavity 5 to the bottom of the big pipe cavity 4. The dropper adding the sperms does not pass through sperm swimming-up liquid in the big pipe cavity 4 so that no spermatic serum pollutes the sperm swimming-up liquid in the big pipe cavity 4. The sperm swimming-up liquid in the big pipe cavity 5 is only roiled even through bubbles produce or operation is in failure during the sediment of the added sperms, and the sperm swimming-up liquid in the small pipe cavity 4 can not be influenced. After the sperm sediment is added at the bottom in the big pipe cavity 5 and the sperms swim-up for 30min, the swum-up sperms are absorbed from the upper part of the small pipe cavity 4 and are used for eutelegenesis in the uterine cavity or external fertilization.
Description
One, technical field
The utility model relates to a kind of medical appliance, exactly is a kind of sperm swim-up pipe.
Two, background technology
In auxiliary procreation technology, no matter be to be ins's (sperm after will washing injects uterine cavity), still vitro fertilization-embryo implanting (tube-test baby techniques, make its fertilization in external sperm and ovum are mixed), sperm is all essential through the washing upstream.At present the upstream tube that uses is exactly the round bottom test tube of common 5ml.Before the upstream, the sperm swim-up liquid that adds earlier 1ml in the round bottom test tube of 5ml is standby.After treating that the sperm washing is centrifugal, with suction pipe as much as possible all supernatant liquors of sucking-off abandon, again evenly with remaining sperm precipitation piping and druming, after with suction pipe sperm being precipitated sucking-off, the round bottom test tube bottom of 1ml sperm swim-up liquid is equipped with in careful insertion, slowly add the sperm precipitation, cover cap test tube, upstream 30 minutes.
The aforesaid problem that adds the existence of sperm intermediate processing is: when 1, with suction pipe the sperm precipitation being added to round bottom test tube bottom, the outer wall of dropper is stained with sticking refining composition and can be added to from top to bottom in each layer of 1ml sperm swim-up liquid.2, how carefully no matter operate, have the refining composition directly to be mixed in the upper strata of 1ml sperm swim-up liquid often; Or alveolate generation, the floating of bubble can drive each layer that refining is mixed into sperm swim-up liquid.This in the sperm swim-up process, the refining that causes because of manual operation is mixed into the fertilization process that sperm swim-up liquid upper strata can have a strong impact on sperm and ovum, not only can directly reduce rate of fertilization, thereby reduced patient's portable embryo number, also influential to after fertilization embryo's potentiality of development simultaneously, the patient is brought about great losses.
Three, summary of the invention
Sperm swim-up pipe provided by the utility model does not have the upper strata that the refining composition is mixed into the sperm nutrient solution when being intended to guarantee that sperm precipitation is added to sperm swim-up liquid bottom; Can because of the generation that adds sperm when precipitation bubble and bubble is not floating refining be mixed in the sperm swim-up liquid.Technical problem to be solved is to improve the structure of existing sperm swim-up pipe.
Thinking of the present utility model is to separate with arc-shaped partition 6 in the sperm swim-up pipe, make upstream tube be divided into two tube chambers, be that tubule chamber 5 has hole and big tube chamber 4 bottoms to communicate with big tube chamber 4. but in the bottom in tubule chamber 5, the sedimentary dropper of sperm is housed like this reaches the bottom in tubule chamber 5, with precipitation be added to the bottom after, because tubule chamber 5 has the bottom of a hole and big tube chamber 4 to communicate, the sperm precipitation that is added to 5 bottoms, tubule chamber will be because the effect of gravity will flow to the bottom of big tube chamber 4, after sperm precipitation added, dropper takes out, the dropper periphery is stained with sticking refining composition and only can be polluted sperm swim-up liquid in the tubule chamber 5 like this, even alveolate generation, only can stir and make muddy the sperm swim-up liquid in the tubule chamber 5, the upstream liquid in the big tube chamber 4 can not be subjected to dropper periphery refining yet, bubble, the refining that misoperation etc. cause has polluted.Treat sperm swim-up after 30 minutes, the sperm swim-up liquid upper strata absorption sperm in big tube chamber 4 just can be used for ins or in vitro fertilization.
The sperm swim-up pipe that the utility model is alleged, comprise sperm swim-up pipe 1 and sperm swim-up pipe lid 3, difference with the prior art is to have set up an arc-shaped partition 6 in original sperm swim-up pipe, makes the sperm swim-up pipe be divided into two tube chambers, i.e. tubule chamber 5 and big tube chamber 4.Tubule chamber 5 volume have only the volumetrical 1/10th of big tube chamber 4, the diameter in tubule chamber 5 is slightly thicker than the dropper diameter that adds sperm precipitation usefulness.In the arc-shaped partition bottom one hole is arranged, make 5 bottoms, tubule chamber and big tube chamber 4 communicate.Add the sperm precipitation from tubule chamber 5, can flow to the bottom of big tube chamber 4 by base apertures.
After the sperm precipitation was added to the bottom, the upstream can be used for ins or in vitro fertilization from absorption sperm swim-up liquid in the big tube chamber 4 after 30 minutes.
Four, description of drawings
Fig. 1 is a sperm swim-up tubular construction synoptic diagram, has an arc-shaped partition 6 that the sperm swim-up pipe is divided into tubule chamber 5 and big tube chamber 4 in the pipe.
Fig. 2 is the vertical view from top to bottom of this sperm swim-up pipe.
Fig. 3 is the cap structure figure of this sperm swim-up pipe.
Five, embodiment
In conjunction with the accompanying drawings, non-limiting examples is described below:
With nonpoisonous and tasteless medical science plastics (glass) processing sperm swim-up pipe (Fig. 1) and sperm swim-up pipe lid (Fig. 3).
As shown in Figure 1, in the sperm swim-up pipe, there is an arc-shaped partition 6 that the sperm swim-up pipe is divided into tubule chamber 5 and big tube chamber 4.
There is a hole that the bottom in tubule chamber 5 and the bottom of big tube chamber 4 are communicated in the bottom of arc-shaped partition 6.The sperm that adds from tubule chamber 5 precipitates, and can flow to the bottom of big tube chamber 4 by tubule chamber 5 bottom holes.
