The invention relates to the field of poultry embryo cultivation, in particular to a blood vessel holder for collecting blood of chicken embryos.
Background
With the improvement of the living standard of the substances, the demand of people for meat and eggs is rapidly increased, and the rapid development of poultry breeding is promoted. Poultry refers to birds which are artificially kept, generally animals of the families Phasianidae and Anatidae, such as chickens, ducks, geese and the like, and birds of other families, such as turkeys, pigeons, quails and the like. The young seedlings are easily affected by environmental factors such as temperature, humidity, oxygen content in air and the like in the hatching process, so that the hatching rate is affected, and therefore, workers need to sample and dissect the young seedlings at different stages of the young seedling development, observe the development condition of the embryo, and perform a blood drawing test on the embryo to further judge the development condition of the embryo.
When the embryo of the young seedling is subjected to blood drawing, a worker generally separates a blood vessel by using a glass rod and supports the blood vessel so as to facilitate the blood drawing, but the blood vessel is generally adhered to a chorioallantoic membrane, the volume of the glass rod is too large, the blood vessel can be effectively separated by being matched with other instruments, and the operation efficiency is slowed down because the surface of the glass rod is smooth and the blood vessel is easy to slide and a needle head is difficult to aim at the blood vessel for blood drawing; in addition, because the blood vessel can not be effectively fixed, the blood vessel is easy to break in the puncture process to cause embryo hemorrhage and result in young seedling death, thereby causing the failure of the whole dissection process and wasting the test sample.
It is seen that improvements and enhancements to the prior art are needed.

FIG. 2 is an exploded view of the blood vessel holder for collecting blood from chicken embryo according to the present invention.
Detailed Description
The invention provides a blood vessel holder for collecting blood of chick embryos, which is further described in detail below by referring to the attached drawings and embodiments in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Referring to fig. 1 and 2, the present invention provides a blood vessel holder for collecting blood from chicken embryo, which comprises a blood vessel holding block 1 and a support rod 2, wherein the blood vessel holding block 1 comprises a puncture part 1.1, a holding part 1.2 and an installation part 1.3 which are connected in sequence, the holding part is provided with a plurality of arc-shaped grooves 1.4 for holding blood vessels, the extension direction of the arc-shaped grooves 1.4 is perpendicular to the extension direction of the blood vessel holding block 1, and the installation part of the blood vessel holding block is fixedly connected with the support rod. Here, in order to reduce the occurrence of slipping between the finger grip struts, the struts are provided with anti-slip threads (not shown).
When the blood vessel puncture positioning device is used, a tester holds the supporting rod 2 with one hand, penetrates chorioallantoic membrane by using the puncture part 1.1, then the arc-shaped groove of the supporting part is positioned below a blood vessel, and then the supporting rod is lifted to clamp the blood vessel into the arc-shaped groove 1.4 to realize the positioning of the blood vessel, so that the blood vessel is prevented from sliding due to blood drawing through needle puncture, the success rate of blood drawing is ensured, and the operation efficiency is improved.
