Abstract

The utility model aims to provide an in vitro fertilization culture dish for optimizing sperms, which is capable of realizing one-to-one fertilization. The in vitro fertilization culture dish for optimizing the sperms comprises a dish plate and a dish cover and has the key points that the dish plate is provided with a sperm storage pool and a sperm optimization pool, wherein the sperm storage pool and the sperm optimization pool are connected through an optimization channel, and the sperm optimization pool is connected with one or more than one ovum pool through a fertilization channel. The in vitro fertilization culture dish for optimizing the sperms not only is capable of optimizing the treated sperms once again but also is capable of binding the sperms with ovums in vitro one to one, is convenient for laying a foundation for the one-to-one observation of subsequent culture and has very high practicability.

Description

A kind of petridish in vitro fertilization of preferred sperm

Technical field

The utility model belongs to the medical treatment consumptive materials technical field, specially refers to a kind of petridish in vitro fertilization of preferred sperm.

Background technology

The patent No. is that 200720131697.1 utility model discloses a kind of ware in vitro fertilization; Comprise fertilization ware and ware lid; The fertilization ware is provided with hole of putting ovum and the hole of putting sperm, between two holes at least one passage is arranged, and has by-path to connect the storage hole in the both sides of passage.With putting into the hole of putting ovum after the ovum washing of taking out; Sperm through upper reaches washing is put into the hole of putting sperm; Some quick straightaway sperms can be swum over to the Kong Zhongyu ovum of putting ovum through passage and combine fertilization; Thereby realized preferred to sperm, increased the chance of high-quality sperm and ovum fertilization.The weak point of above-mentioned ware in vitro fertilization is with the ovum fertilization of putting together, can't man-to-manly be fertilized.

The utility model content

The purpose of the utility model is the petridish in vitro fertilization that proposes a kind of preferred sperm that can realize being fertilized one to one.

The petridish in vitro fertilization of the preferred sperm of the utility model comprises ware dish and ware lid; Key is that said ware dish is provided with storage sperm pond and preferred sperm pond; Said storage sperm pond links to each other through preferred passage with preferred sperm pond, and said preferred sperm pond links to each other with one or more ovums pond through the fertilization passage.

At first in each ovum pond, respectively put an ovum; In storing the sperm pond, add the seminal fluid of handling well then; Good sperm is swum in the preferred sperm pond through preferred passage to make the forward direction motility, swims over to through the fertilization passage and accomplishes fertilization in the ovum pond, reaches the sperm purpose of selecting vigor excellent once more; Can man-to-man completion be fertilized simultaneously, for the man-to-man observation of follow-up cultivation provides the basis.

Further, said preferred passage is a beeline channel, and quick so straightaway sperm can be swum in the preferred sperm pond through preferred passage, and then combines fertilization with ovum, thereby has realized preferred to sperm.

Further, said preferred passage is a spirality channel, like this can be on onesize ware dish, and preferred as far as possible longways passage is set, thereby has realized preferred to sperm.

The petridish in vitro fertilization of the preferred sperm of the utility model not only can be preferred once again with the sperm of having handled well, can also combine outward by the smart oophyte of man-to-man completion simultaneously, is convenient to have good practicability for the man-to-man observation of follow-up cultivation provides the basis.

Fig. 2 is the vertical view of petridish in vitro fertilization of the preferred sperm of embodiment 2.

Embodiment

Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are done further to specify to embodiment.

Embodiment 1:

(ware that do not draw among figure lid) as shown in Figure 1; The petridish in vitro fertilization of the preferred sperm of present embodiment comprises ware dish 1 and ware lid; Ware dish 1 is provided with and stores sperm pond 2 and preferred sperm pond 3; Store sperm pond 2 and link to each other through linear preferred passage 4 with preferred sperm pond 3, preferred sperm pond 3 links to each other with a plurality of ovums pond 6 through radial fertilization passage 5.

At first in each ovum pond 6, respectively put an ovum; In storing sperm pond 2, add the seminal fluid of handling well then; Good sperm is swum in the preferred sperm pond 3 through preferred passage 4 to make the forward direction motility, swims over to through fertilization passage 5 and accomplishes fertilization in the ovum pond 6, reaches the sperm purpose of selecting vigor excellent once more; Can man-to-man completion be fertilized simultaneously, for the man-to-man observation of follow-up cultivation provides the basis.

Embodiment 2:

As shown in Figure 2, different with embodiment 1 is, the preferred passage 4 of present embodiment is a volution, the distance of moving about with the sperm that extends as far as possible, thus realize preferred to sperm.

Claims

1. the petridish in vitro fertilization of a preferred sperm; Comprise ware dish and ware lid; It is characterized in that said ware dish is provided with storage sperm pond and preferred sperm pond; Said storage sperm pond links to each other through preferred passage with preferred sperm pond, and said preferred sperm pond links to each other with one or more ovums pond through the fertilization passage.

2. the petridish in vitro fertilization of preferred sperm according to claim 1 is characterized in that said preferred passage is a beeline channel.

3. the petridish in vitro fertilization of preferred sperm according to claim 1 is characterized in that said preferred passage is a spirality channel.
