Description

Bovine blood sampling device

[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of experimental equipment, in particular to a bovine blood sampling device.

[ background of the invention ]

The large-scale and intensive breeding mode easily causes cattle to suffer from pathological changes. In order to make a correct diagnosis and analysis of an epidemic disease, frequent serological tests for an epidemic disease need to be carried out on a herd of cattle. At present, a bovine blood sampling worker generally finds the jugular vein and inserts the jugular vein obliquely according to the past work experience of the worker. This approach is characterized by experience-based, blind operation, and is a significant challenge for an inexperienced bovine blood sampling worker. After the syringe needle inserted the blood vessel, because there is not securing device, the easy relative angiogenesis relative movement of syringe needle, artificial shake, touch or the ox body rocks, all make the syringe needle touch the vascular wall once more easily, the fish tail vascular wall breaks through the vascular wall once more even, the influence sample goes on smoothly. Moreover, the syringe needle touches the vascular wall once more, very easily arouses the intense stress response of ox, takes place anger to move, not only influences the sample and goes on smoothly, still can influence blood sampling staff's personal safety even. The sampling of bovine blood is a complex task requiring a lot of human hands. In the blood sampling process, because the ox is the state of standing, the blood sampling part is in the jugular vein, and the sample staff can only select different sample postures according to the size of the ox physique, squats, half squats or stands, has increased the blood sampling degree of difficulty. In actual operation, personnel are too many, not only the waste of manpower resources, simultaneously, when the ox should be reacted too big, personnel are too many and can lead to staff's activity space narrow and small, are unfavorable for avoiding danger, cause bodily injury easily. Therefore, in the blood sampling process, the technical problem to be solved at present is to stabilize the displacement of the blood sampling needle and the blood vessel by taking a simple and quick blood sampling technology as guidance and reduce the number of sampling participants.
