Abstract

The utility relates to an in vitro fertilization dish which comprises a fertilization dish (1) and a dish cap (2), the fertilization dish (1) is provided with a hole (3) which is used for containing ova and a hole (4) which is used for containing sperms, at least a passage (5) is arranged between the hole (3) and the hole (4), a branch passage (6) is arranged at both sides of the passage (5) to connect a store hole (7). After being taken out and washed, the ovum is put into the hole (3), the sperms which are washed at upstream is put into the hole (4) and some sperms which move fast in a straight line swim into the hole (3) by the passage (5) so as to fertilize with the ovum. The passage (5) has the function similar to ovarian tube and can achieve optimal selection of sperms, thereby increasing the opportunity for fertilization of high-quality sperm and high-quality ovum.

Description

A kind of external fertilization ware

One, technical field

This utility model relates to a kind of medical appliance, exactly is a kind of external fertilization ware.

Two, background technology

External fertilization ware used in everyday is distributed with some holes independently separately on it.External fertilization is exactly that sperm and ovum are directly added in the hole of the ware of being fertilized, and covers ware lid back and cultivates, and makes sperm and ovum combination.

Sperm is to pass through uterus, fallopian tube under the normal physiological situation, has only to have passed through and trudges or passed through the sperm that fierce long distance race arrives around the ovum smoothly and just had an opportunity and the ovum combination.And the structure of existing external fertilization ware does not have the effect of the survival of the fittest.

Three, summary of the invention

External fertilization ware provided by the utility model is intended to guarantee high-quality sperm fertilization, and technical problem to be solved is to improve the structure of existing external fertilization ware.

Thinking of the present utility model is the physiological process that simulation is become pregnant, and sperm and ovum are placed two holes respectively, has passage to connect between two holes, makes the process of sperm through a survival of the fittest.

The external fertilization ware that this utility model is alleged, comprise fertilization ware 1 and ware lid 2, difference with the prior art is that fertilization ware 1 is provided with storing ovum, the hole 3 (culture hole) of back cultivation germ cell and the hole 4 of putting sperm earlier, between hole 3 and hole 4, there is at least one passage 5 to be connected, has by-path 6 to be communicated with storage hole 7 in the both sides of passage 5.

In operating process, need to add culture fluid, for preventing that careless manipulation or accident from causing the excessive pollution operating board of culture fluid, incubator and ware lid etc., this culture fluid is excessive also to have increased the contaminated chance of culture fluid in the hole, is the safety that guarantees operation, in the hole 3 and the periphery in hole 4 safety groove 8 is set.

Simultaneously the height in hole 3, hole 4, passage 5, by-path 6 and storage hole 7 is lower than the outer height of safety groove 8, can stop the periphery that spreads to culture dish of excessive culture fluid on the one hand, can make embryo culture required gas communication such as CO2 more smooth on the other hand.

Need to observe the situation of ovum in the culture hole in operation with anatomical lens, if vertical connection the between the hole wall inner surface of culture hole and the hole basal surface, the dead angle that its intersection is observed often, for convenient seeking, observe ovum and prevent loss, camber line is connected between the hole wall inner surface of culture hole and the hole basal surface.As shown in Figure 2.

With take out ovum put into hole 3 after through washing, put into hole 4 through the sperm of upstream washing, after after a while, some quick straightaway sperms can be swum in the hole 3 by passage 5 and combine fertilization with ovum.

This external fertilization ware changes traditional fertilization method, sperm and ovum are separated separately, the hole 4 of spermiation and put between the hole 3 of ovum and set up passage 5, similar oviducal function is arranged, because ovum and on every side the excretory molecular substance of granular cell sperm is had inducing action, straight-line and speed faster sperm preferentially by passage 5 and ovum combination, and slow-footed particularly paramophia and can not straight-line sperm will flowing into along by-path 6 is eliminated in the storage holes 7, thereby reach sperm is preferably acted on, increased the chance of high-quality sperm and ovum fertilization.

Sperm directly is added in the culture hole of putting ovum, and inevitable remaining have the refining composition, and the existence of refining all has negative effect to the combination of sperm and ovum and embryo's growth.This culture dish is placed apart with sperm and ovum, has avoided this negative effect effectively.

Four, description of drawings

Fig. 1 is the structural representation of this fertilization ware, and hole 3, hole 4 and the passage 5 etc. of the external fertilization usefulness of two covers are arranged in the ware.

Fig. 2 is culture hole (hole a 3) A-A profile, and signal hole wall inner surface is connected with hole basal surface camber line.

Fig. 3 is the three-dimensional effect diagram of Fig. 1, and solid show structure of the present utility model makes it clearer.

Fig. 4 is a ware lid 2.

Five, the specific embodiment

In conjunction with the accompanying drawings, non-limiting examples is described below:

With medical science glass (plastics) processing fertilization ware 1 and ware lid 2.

Hole 3, hole 4 and the passage 5 etc. of the external fertilization usefulness of two covers are set on fertilization ware 1 as shown in Figure 1.Promptly be provided with hole 3 (culture hole) and two orthogonal holes 4 of two circles.Between hole 3 and hole 4, two passes 5 is arranged, each have five by-paths 6 in the both sides of every passage 5 and connect storage hole 7.In two culture hole (hole 3), camber line is connected between hole wall inner surface and the hole basal surface, as shown in Figure 2.

Periphery along two holes 3, hole 4 is provided with safety groove 8.

The height in hole 3, hole 4, passage 5, by-path 6 and storage hole 7 is lower than the outer height of safety groove 8, can stop the periphery that spreads to culture dish of excessive culture fluid on the one hand, can make embryo culture required gas communication such as CO2 more smooth on the other hand.
