Description

Blood collection device for poultry

technical field

The utility model relates to a poultry blood sampling device, in particular to a poultry blood sampling device, which belongs to the technical field of poultry sampling.

Background technique

Poultry is an important experimental animal model. When studying the physiological activities of calcium metabolism or hormone secretion, and the metabolic kinetics of poisons or drugs in poultry, it is often necessary to collect blood from poultry multiple times in a row to meet the follow-up detection and testing requirements. Require. The traditional blood collection method is multiple acupuncture blood collection in the wing vein, and the needle is directly connected to the syringe. The blood collection needs to pull the needle bar back, so two hands are required, which makes blood collection very troublesome. In addition, the blood collection volume cannot be limited during blood collection. Through visual judgment, too much or too little blood collection often leads to repeated blood collection, which not only causes repeated damage to poultry, but also causes blood leakage under the skin at the blood collection site due to poor hemostasis, causing blurred vision, making it difficult to carry out blood collection work, and some even The test results were inaccurate due to the blood taking time being too long. In addition, the previous blood collection work required the assistance of multiple people, which not only easily frightened the poultry and affected their physiological functions such as egg production, but also caused stress and changes in hormones and other indicators of the poultry.
