Problems solved by technology

[0002] At present, there are few devices dedicated to the in vitro operation and cultivation of mammalian embryos. In vitro washing generally uses the petri dish micro-drop method and glass ovipositor. Droplets and time-consuming, prolonging the residence time of embryos in vitro
The glass egg picker must be reused every time it is used up. If it is not washed thoroughly, it will affect the development of the embryo. At the same time, a single egg picker is not convenient to use

Embodiment Construction

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings .

[0016] The invention provides a device for in vitro operation and culture of mammalian embryos, which can quickly and more conveniently wash the embryos during the embryo operation and improve the embryo development rate. The device comprises a petri dish 1 and a petri dish lid 2 . figure 1 It is a schematic structural view of a petri dish 1 according to an embodiment of the present invention, including an operating device tray 10, in which several rows of operating cells 11 are arranged, in this example, 6 rows of 4 operating cells 11 in each row. The operation chamber 11 is used for the in vitro operation o...

Abstract

The invention provides a device for operating and culturing an animal embryo in vitro, which can be used for rapidly and more rapidly and conveniently carrying out embryo washing in embryo operation, so that the embryo developmental rate is improved. The device disclosed by the invention comprises a culture dish and a culture dish cover, wherein the culture dish comprises small operation chambers for embryo in-vitro operation in vitro. The culture dish cover comprises a plurality of small operation chamber covers capable of being independently turned over. Each small operation chamber cover is used for covering a row of small operation chambers. According to the device for operating and culturing the animal embryo in vitro, the defects in the conventional embryo operation in vitro of time waste and inconvenience can be overcome. The embryo is washed in a process of freely falling down from the upper part of operation liquid to the bottom of the operation liquid without carrying out excessively blowing and beating on the embryo, so that the embryo is relatively easy to absorb. The water volatilization of the other rows of non-operated small operation chambers can be reduced through the independent small covers. The device disclosed by the invention is a plastic product, can be repeatedly used an also can be disposably used.

Description

technical field [0001] The present invention relates to devices for in vitro manipulation and culture of mammalian embryos. Background technique [0002] At present, there are few devices dedicated to the in vitro operation and cultivation of mammalian embryos. In vitro washing generally adopts the petri dish micro-drop method and glass ovipositor. Droplets and time-consuming prolong the residence time of embryos in vitro. The glass egg picker must be reused every time it is used up. If it is not washed thoroughly, it will affect the development of the embryo. At the same time, a single egg picker is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for in vitro operation and culture of animal embryos, which can quickly and more quickly wash embryos during embryo operation and improve the embryo development rate. [0004] The device of the present invention includes a petri dish and ...
