Description

Technical Field

[0001] The utility model relates to the technical field of blood collectors, in particular to a pig ear vein blood collector. Background Art

[0002] In animal experiments, researchers may need to collect blood samples from pigs regularly or irregularly to study the effects of certain diseases or drugs. The pig ear vein blood collector provides a convenient and quick way to obtain these blood samples. It can help researchers and veterinarians quickly and accurately obtain blood samples from pigs, providing important basis for subsequent experiments and treatments.

[0003] In the prior art, a Chinese patent document with publication number CN219516302U proposes a pig ear vein blood collector, which, when in use, inserts the bottom end of the block into the EP tube, and presses the block and the EP tube tightly with the thumb, so that when the draw rod is pulled upward, the piston is driven to move upward, and the air in the EP tube is extracted to generate negative pressure, so that the blood sample can be extracted through the needle, the hose and the fixed tube and enter the EP tube. Therefore, when collecting blood from the ear vein of the sow, the blood sample is directly collected into the EP tube, which is convenient for centrifugal separation of serum and also avoids the problem of syringe contamination during direct collection. In subsequent use, only the hose and the needle need to be replaced. , and the pig's ear swings during blood drawing, and the provided hose can have no effect on blood drawing, thereby improving the blood drawing effect of the blood collection device. The above patent document is consistent with the prior art in that it does not have a fixing component for the pig's ear. During the blood drawing process, the pig's ear will shake, causing the pig's ear to bend, which will cause the needle in the venous tube to penetrate the venous tube and cause the needle to be blocked, resulting in blood circulation difficulties and blood drawing difficulties. Furthermore, we disclose a pig ear venous blood collector to meet the actual needs of traditional pig ear venous blood collectors that do not have a pig ear fixing component, which causes the needle to be blocked after the pig's ear is bent, making blood circulation difficulties and blood drawing difficulties. Utility Model Content
