Abstract
The utility model provides a test tube rack capable of facilitating sperm to swim upward or downward, which is used to store sperm suspension and sperm medium. The test tube rack comprises a bottom plate and a supporting plate arranged on the bottom plate. A plurality of locating grooves are arranged on the bottom plate and a plurality of supporting grooves are arranged on the supporting plate, wherein the locating grooves are used for obliquely placing test tubes and for supporting the bottom of the test tubes; the supporting grooves are used for supporting the head of the test tubes. A baffle extends upward from the edge of the bottom plate. A plurality of through holes are arranged on the bottom plate and the supporting plate. The bottom plate and the supporting plate can be manufactured integrally. The angle between the bottom plate and the inclined test tubes is 30 to 60 degrees. In order to ensure that the test tubes are stably and reliably placed, the supporting grooves are inclined arc-shape grooves which can attach the external surface of the inclined test tubes. The utility model has the advantages that the test tubes containing sperm suspension and sperm medium can be obliquely placed on the test tube rack, the area of the liquid surfaces is increased, the test tube rack facilitates the sperm to swim upward or downward and the success rate of the test-tube baby or the artificial insemination is improved.
Description
[technical field]
The utility model relates to a kind of test-tube stand, relates in particular to a kind of test-tube stand of storing sperm suspension and nutrient solution, helping sperm swim-up or downstream of being used to.
[background technology]
Birth along with the first in the world example tube baby, associating embryo transfer technology in vitro fertilization has brought Gospel for many infertile people, in the last few years, human auxiliary procreation technology has had very big development, every technology reaches its maturity, and is worldwide also improving constantly gradually as artificial insemination, technology such as in vitro fertilization.But the success ratio of above-mentioned technology depends on a lot of aspects, and the form of sperm and activity have very big influence to sperm quality, wherein just comprise the placement condition and the environment of sperm suspension and nutrient solution.Usually, with seminal fluid take out put into test tube after, need be optimized processing, adopt upstream or downstream method or density gradient centrifugation to handle more.Yet the test-tube stand that present existing testing laboratory or when check sampling are used to put test tube is the supporting support body that is provided with a plurality of putting holes and is arranged in parallel, and described support body all is to be used for test tube is uprightly placed, and overflows to avoid the liquid in it.But the test-tube stand that adopts this structure is difficult to realize sperm upstream voluntarily as much as possible or downstream when the optimization process that is used for seminal fluid.
[utility model content]
Technical problem to be solved in the utility model is to overcome above-mentioned prior art defective, provides a kind of and guarantees that sperm swim-up or downstream being used among nutrient solution store the test-tube stand of sperm.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of test-tube stand of being convenient to sperm swim-up or downstream, comprise a base plate and be arranged at supporting plate on the described base plate, offer respectively on described base plate and the supporting plate and can hold test tube and tilt to place, be used to the support slot that supports the locating slot of test tube bottom and be used to support the test tube head.
Preferably, the angle between the test tube of described base plate and inclination is 30～60 degree.
Further, described base plate and supporting plate are integrally manufactured.
Described base plate is or/and offer at least more than one through hole on the supporting plate.
Described bottom edge can extend upward a baffle plate.
Described support slot be one can with the oblique arc groove of the test tube outside surface applying of tilting.
The utility model provides a kind of test-tube stand that is used to store sperm, tilts to be positioned on the test-tube stand when test tube is deposited, and can increase the interfacial area of sperm suspension and nutrient solution, is convenient to moving about up or down of sperm.
The utility model is described in further detail below in conjunction with drawings and Examples.

[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1, the utility model embodiment one comprises a base plate 1, and described base plate 1 is provided with a supporting plate 2, and both can be integrally manufactured, or is fixedly connected into " L " shape by web member; On described base plate 1, also be provided with locating slot 11, described supporting plate 2 is provided with support slot 21, and described locating slot 11 and support slot 21 centers should be on same straight lines.During use, test tube 3 tiltables that sperm suspension 5 and nutritive medium 6 be housed are placed in that (sperm suspension 5 of Fig. 1 is above test tube 3 on the test-tube stand that above-mentioned base plate 1 and supporting plate 2 constitute, nutritive medium 6 below, be the downstream mode), wherein locating slot 11 is an arc groove, be used to support test tube 3 bottoms, should be convenient to the storing position of test tube 3 is positioned, slippage in the time of can avoiding test tube 3 to put simultaneously; Described support slot 21 is used to shelve the head of test tube 3, can be used as the supporting of test tube 3 heads, like this, just test tube 3 can be tilted place and it is put to stablize.When tilt placing, the angle between test tube 3 and the base plate 1 is about 30～60 degree, but the area at different liqs interface in the enlarged tube, and the interior sperm swimming performance up or down of test tube 3 when increase is deposited is for tube baby's success ratio provides further condition.Described support slot 21 be designed to one can with the oblique arc groove of test tube 3 outside surface applying of tilting, stablizing when guaranteeing that test tube 3 is placed, reliably do not rocked.
In addition, as shown in Figure 1, among the utility model embodiment, locating slot 11 on the described base plate 1 and supporting plate 2 upper support grooves 21 can be as required respectively at setting in a row on base plate 1 and the supporting plate 2, to deposit more test tube 3.
The utility model or/and on the supporting plate 2, also offer some through holes 4, helps gas flow at described base plate 1, in the time of in being seated in incubator or other accommodation tools, is convenient to the fusion with surrounding environment.
Referring to Fig. 2 and Fig. 3, the utility model embodiment two also comprises a base plate 1, on described base plate 1, also be provided with a supporting plate 2, different with embodiment one is, described base plate 1 edge can extend upward a baffle plate 12, locating slot 11 is one to be arranged at the skewed slot on base plate 1 edge and baffle plate 12 sides, and its bottom can be held in the skewed slot when test tube 3 was put, and baffle plate 12 is used for test tube 3 is positioned.Add man-hour, base plate 1, supporting plate 2 and baffle plate 12 can adopt same board-like material, are bent into shape shown, again locating slot 11, support slot 21 are carried out following process and get final product.
The sperm suspension 5 of present embodiment accompanying drawing 3 is positioned at test tube 3 belows, and nutritive medium 6 is the upstream mode up.
The above only is the utility model preferred embodiment; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
