Description
Technical Field
The utility model relates to an animal baoding technical field, in particular to piglet anterior vena cava blood sampling baoding device.
Background
The collection of animal blood samples is an essential step in the processes of breeding production and quarantine inspection. As an important economic animal in China, the pig needs to collect venous blood to monitor epidemic diseases, detect vaccine titer, determine physiological indexes and the like in pig production. The blood sampling parts of the pigs mainly comprise auricular veins and anterior vena cava, the auricular veins have less bleeding amount and are difficult to insert needles, and the anterior vena cava is mainly used for blood sampling in clinic. The anterior vena cava is located directly anterior to the first pair of ribs and the manubrium, i.e., where the two forelimbs meet the trachea. The anterior vena cava is closer to the body surface as it goes to the head, but is thinner and deeper as it goes to the chest and further away from the body surface. The pig is kept in a standing posture by using a mouth kissing rope aiming at the retaining mode of an adult pig, one end of the mouth kissing rope is sleeved on the pig mouth corner of the upper lip of the pig to be tensioned, the other end of the mouth kissing rope is used for finding the place where the pig can be firmly fastened nearby, the optimum height of the fastening and the best strength of the foot of the pig which can touch the ground can be achieved, and then the needle is inserted from the anterior vena cava to take blood. Because the blood vessels of piglets (pigs below 25 kg) are thin, the piglets need to be kept with the head facing downwards and the abdomen facing upwards for blood collection so as to flow to the anterior vena cava and conveniently find the blood vessels. Therefore, the standing restraint for adult pigs is not suitable for piglets. At present, the blood sampling of piglets completely depends on manual fixation, can be completed only by matching two persons at least, wherein one person holds two forelimbs of the pig, the pig is held in the bosom in a mode that the head is downward, the abdomen is upward, and the hip faces towards the chest and the abdomen of a fixation person for fixation, the left hand of the other person presses the lower jaw of the pig, and the injector is held by the right hand for blood sampling.
