Protection device for tail vein blood sampling of livestock

Abstract

The present invention provides a protection device for tail vein blood sampling of livestock and relates to the field of medical devices of livestock. A special structure of the protection device is as follows: a plurality of leg protection stop levers are annularly distributed at intervals, and lower ends of the leg protection stop levers are hinged to supporting seats; an elastic energy storagepiece is connected between each leg protection stop lever and the supporting seat, and is configured to enable the corresponding leg protection stop lever to always have a movement trend of incliningfrom a middle part of the supporting seat to an edge part of the supporting seat from bottom to top; a plurality of the leg protection stop levers are sleeved with push rings; and push ring driving mechanisms are arranged on the supporting seats and are configured to drive the push rings to move upwards along a plurality of the leg protection stop levers to gather upper ends of a plurality of theleg protection stop levers and to drive the push rings to move downwards along a plurality of the leg protection stop levers to release the upper ends of a plurality of the leg protection stop levers.The protection device solves a technical problem that in the prior art, in a tail vein blood sampling process of cows or other medium and large livestock, a blood sampler has a risk of being kicked by rear legs of the livestock.

Description

Technical field[0001]The invention relates to the technical field of livestock medical equipment, in particular to a protective equipment for blood sampling from the tail vein of livestock.Background technique[0002]In daily animal disease monitoring, it is necessary to collect blood from livestock. Take cattle as an example. The blood samples of cattle are generally collected by the method of blood collection from the bovine jugular vein. There are often many inconvenience factors when collecting blood from the jugular vein of cattle. It is necessary to touch the cow’s head, which is easy to cause the cow to startle, and the horn is easy to cause the blood collector’s hand, which is dangerous, especially the cow is more stressed, causing economic losses such as reduced milk production. The ox tail vein is collected. The blood collector touches the tail of the ox during the blood collection process. The ox tail nerve is relatively slow, the pain is light, and the stress response to t...

AI Technical Summary

Problems solved by technology

[0003] However, when blood is collected from the ox tail vein, although the stress response of the cow is weak, the blood collector still has the risk of being kicked by the cow's leg during the blood sample collection process.

[0004] Not only cattle, there are such risks in the process of tail vein blood collection for medium and large livestock
