Blood vessel holder for chick embryo blood collection

Abstract

The invention discloses a blood vessel holder for chick embryo blood collection. The blood vessel holder comprises a blood vessel holding block and a supporting rod, the blood vessel holding block comprises a puncture portion, a holding portion and a mounting portion which are sequentially connected, a plurality of arc-shaped grooves for holding blood vessels are formed in the holding portion, theextending direction of the arc-shaped grooves is perpendicular to the length extending direction of the blood vessel holding block, and the mounting portion of the blood vessel holding block is fixedly connected with the supporting rod. According to the blood vessel holder, the puncture portion pierces a chorioallantoic membrane, the arc-shaped grooves of the holding portion are positioned belowthe blood vessels, the supporting rod is lifted to clamp the blood vessels into the arc-shaped grooves, so that the blood vessels are positioned and prevented from sliding when a needle draws blood bypuncture, blood drawing success rate is ensured, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of poultry embryo cultivation, in particular to a blood vessel holder used for blood collection of chicken embryos. Background technique [0002] With the improvement of material living standards, people's demand for meat and eggs has risen sharply, which has promoted the rapid development of poultry farming. Poultry refers to artificially raised birds, generally pheasants and ducks, such as chickens, ducks, geese, etc. There are also other families of birds such as turkeys, pigeons, quails, etc. Young seedlings are easily affected by environmental factors such as temperature, humidity, and air oxygen content during the incubation process, thus affecting the hatching rate. Therefore, the staff needs to sample and dissect the young seedlings at different stages of their development to observe the development of the embryos. The blood test was performed on the embryos to further judge the development of the embryos. ...

AI Technical Summary

Problems solved by technology

[0003] When drawing blood from the embryos of young seedlings, the staff generally use glass rods to separate the blood vessels and hold them in order to facilitate blood drawing, but Because the blood vessels are generally adhered to the allantoic chorion, the glass rod is too large, and other instruments are often needed to effectively separate it. In addition, because the surface of the glass rod is smooth, the blood vessels are easy to slide, and the needle is difficult to align with the blood vessels. Blood drawing slows down the operation efficiency; in addition, because the blood vessels cannot be effectively fixed, the blood vessels are easy to rupture during the puncture process, causing the embryo to hemorrhage and resulting in the death of the seedlings, resulting in the failure of the entire dissection process and wasting test samples
