Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pig blood sampling devices, in particular to a pig anterior vena cava blood sampling and restraint cage. Background Art
[0002] With the intensive development of the pig farming industry, pig diseases are becoming increasingly complex. Many epidemic diseases cannot be diagnosed solely by visual observation of lesions and experience, but require laboratory testing. Blood is a necessary sample for laboratory antibody and antigen testing. Blood samples can be obtained from large pigs through two methods: ear vein blood collection and anterior vena cava blood collection. However, no matter which method is used, the pigs need to be restrained before blood collection can be carried out. Most pig farms use the anterior vena cava blood collection method. Pigs on pig farms vary greatly in size, and they are secured with restraints or ropes. There is no way to adjust the device to suit different pigs. Large and strong pigs can easily break free, making blood collection difficult and inconvenient. Utility Model Content

The main bracket of the left baffle is equipped with a clip for locking or releasing the main bracket to the guide rod. The four sets of guide structures ensure stable fixation and movement of the left baffle. The clip can lock or release the main bracket to the guide rod, thereby clamping or releasing the pig.
[0007] The two ends of the left side of the top baffle and the two ends of the left side of the base are respectively connected and fixed through columns.
[0008] The front door includes a front fixed frame with a rectangular structure, in which a plurality of transverse support bars are arranged. The two ends of the transverse support bars are respectively fixed to the frames on both sides of the front door; the right side of the front door is hinged to the side of the right baffle.

[0011] The top baffle comprises a top fixing frame of a rectangular structure, and a plurality of transverse supporting bars are evenly arranged in the top frame.
[0012] The right baffle comprises a right fixed frame of a rectangular structure, wherein a plurality of vertical support bars are evenly distributed in the right fixed frame.
[0013] The left side baffle includes a main bracket with a rectangular structure, and a number of vertical support bars are evenly distributed in the main bracket. The two vertical support bars close to the rear door side are fixed support bars, and the remaining vertical support bars are detachable support bars.
[0014] The base is a steel plate made of stainless steel, and four corners of the base are respectively equipped with universal wheels with locking structures.
[0015] Compared with the existing technology, the advantages of the utility model are: the cage is simple to manufacture and has no complicated accessories; the space inside the cage is adjustable, suitable for pigs of different sizes, and can fit closely to the pig's body to limit the pig's swing; the operation of fixing the pig's body is simple, which is convenient for large-scale blood collection from the pig's anterior vena cava; the pig's body is fixed firmly, and the four universal wheels at the bottom can be locked, so it will not shake due to the shaking of the pig's body.
