Sunken type influenza virus chick embryo allantoic fluid extraction device

Abstract

The invention relates to the field of viruses, and particularly relates to a sunken type influenza virus chick embryo allantoic fluid extraction device. The sunken type influenza virus chick embryo allantoic fluid extraction device comprises a transportation assembly, a shell breaking assembly, a fluid extraction assembly, a bottom plate, a control button and the like; the bottom plate is fixedly connected with a first fixing plate; and a first connecting block is fixedly connected with a first channel block. When the device is used, the upper cavity position of an eggshell is automatically broken into a cracking state, then the cracked eggshell and an eggshell membrane are torn off together, the phenomenon that the eggshell is scattered is reduced, meanwhile, the phenomenon that the eggshell falls into the chorio-allantoic membrane when the middle of the chorio-allantoic membrane is opened is completely eradicated, meanwhile, the phenomenon that the eggshell falls into the chorio-allantoic membrane when touching the edge of the opening of the chick embryo in the liquid taking process is avoided, pollution is avoided, and overflowing allantoic liquid is automatically prevented from contaminating the eggshell left on the periphery of the upper part of the chorio-allantoic membrane.

Description

technical field [0001] The invention relates to the field of viruses, in particular to a sunken influenza virus chicken embryo allantoic fluid extraction device. Background technique [0002] Viruses are small, simple in structure, contain only one kind of nucleic acid, and must parasitize and multiply in living cells. Virus is a kind of non-cellular life form. It consists of a long nucleic acid chain and a protein shell Composition, the virus does not have its own metabolic mechanism, no enzyme system. Therefore, when the virus leaves the host cell, it becomes a chemical substance without any life activities and cannot reproduce itself independently. Its ability to replicate, transcribe, and translate is carried out in the host cell. When it enters the host cell, it can use the material and energy in the cell to complete life activities and produce according to the genetic information contained in its own nucleic acid. A new generation of viruses like it. [0003] Chicke...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the existing device, when the embryo eggshell is directly crushed, the eggshell fragments are scattered on the upper surface of the choriourin, and when the middle part of the upper surface of the choriourin is perforated, part of the eggshell flows into the inside of the choriourin, and the allantoic fluid At the same time, after the existing device crushes the cavity of the eggshell, some eggshell fragments remain and hang on the edge of the eggshell opening. When the allantoic fluid is extracted and touch the edge of the eggshell opening, the eggshell fragments will fall off In addition, when the existing device perforates the middle part of the upper surface of the choriomeric membrane, the allantoic fluid will overflow to the upper surface of the choriouric membrane, and then be scattered on the upper surface of the choriouric membrane Disadvantages of epitaxial eggshell fragment contamination, technical problems: provide a recessed influenza virus chicken embryo allantoic fluid extraction device
