Abstract

The utility model relates to a reservoir for preserving embryonated egg, including inner tube and urceolus, be equipped with the cavity in its characterized in that urceolus, be equipped with the inner tube in the cavity, inner tube length is less than urceolus length, has seted up the guiding groove on the urceolus, and guiding groove one end extends to the urceolus tip and forms the opening, and the guiding groove other end extends to the inner tube top, and the ring channel has been seted up on the inner tube top. Compared with the prior art, the utility model, its advantage lies in: the guiding groove has been seted up including inner tube and urceolus to this device on, guiding groove one end extends to the urceolus tip and forms the opening, makes things convenient for inserting of embryo's straw, clearance between outer lane and the inner circle constitutes the ring channel, can put into many straws simultaneously, avoids mutual interference between the straw.

Description

A kind of reservoir vessel for preserving fertilized egg

[technical field]

The utility model relates to embryo culture equipment technical field, specifically a kind of reservoir vessel for preserving fertilized egg.

[background technology]

Along with the development of IVF Embryos technology, the application of Embryo Cryopreservation Technology is more and more extensive, at present, frozen embryo carrier mainly contains two kinds, a kind of is a plastics straw for tampon, sequencing is freezing to be at a slow speed applicable to embryo, another kind of for being specifically designed to the straw of embryo vitrifying freeze, is applicable to embryo vitrifying snap frozen.

It is fast that vitrification has chilling rate, and avoid cold crystalline substance to be formed, reduce and coldly melt damage and simple operation and other advantages, by clinical observation, the method can improve the survival rate after embryo or egg freezing recovery and Pregnancy Success rate.In recent years, most of supplementary reproduction mechanism adopts glass freezing, concrete grammar is, by with capillary, the micro liquid containing embryo is transferred to the ad-hoc location that glass freezing carries bar, glass freezing being carried bar inserts in straw again, finally drop into freezen protective in liquid nitrogen, requiring in operating process, when inserting straw, take very much eyesight and time, straw position inserting error can make mutually to interfere between straw, and misoperation also can cause embryo or ovum to lose.

[summary of the invention]

The purpose of this utility model is the deficiency according to glass freezing straw in existing vitrification, use a kind of novel structure, easy to operate, for preserving the reservoir vessel of fertilized egg.

To achieve these goals, design a kind of reservoir vessel for preserving fertilized egg, comprise inner core and urceolus, be provided with cavity in urceolus, be provided with inner core in cavity, inner core length is less than urceolus length, urceolus offers guiding groove, guiding groove one end extends to urceolus end and forms opening, and the guiding groove other end extends to inner core top, and inner core top offers cannelure.

Described inner core top is provided with outer ring and inner ring, is provided with gap between outer ring and inner ring, and looping groove, offers square groove in the middle part of inner ring.

Compared with the existing technology, its advantage is the utility model: this device comprises inner core and urceolus, and urceolus offers guiding groove, and guiding groove one end extends to urceolus end and forms opening, facilitates the insertion of embryo's straw; Gap looping groove between outer ring and inner ring, can put into branched straw simultaneously, avoids mutually interfering between straw.

[embodiment]

Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, this device comprises inner core and urceolus, as shown in Figure 2, by inner core, the reservoir vessel of urceolus composition can be set on cylinder stent, cavity is provided with in urceolus, inner core is provided with in cavity, inner core length is less than urceolus length, urceolus offers guiding groove, guiding groove one end extends to urceolus end and forms opening, the insertion guiding groove other end of embryo's straw is facilitated to extend to inner core top, inner core top offers cannelure, inner core top is provided with outer ring and inner ring, gap is provided with between outer ring and inner ring, looping groove, branched straw can be put into simultaneously, avoid mutually interfering between straw, square groove is offered in the middle part of inner ring.

Claims

1. one kind for preserving the reservoir vessel of fertilized egg, comprise inner core and urceolus, it is characterized in that being provided with cavity in urceolus, inner core is provided with in cavity, inner core length is less than urceolus length, and urceolus offers guiding groove, and guiding groove one end extends to urceolus end and forms opening, the guiding groove other end extends to inner core top, and inner core top offers cannelure.

2. a kind of reservoir vessel for preserving fertilized egg as claimed in claim 1, it is characterized in that described inner core top is provided with outer ring and inner ring, be provided with gap between outer ring and inner ring, looping groove, offers square groove in the middle part of inner ring.
