Embodiment 1

[0023] like figure 2 As shown, a milk sampler for modern pastures includes an air pressure regulator 1 and a suction pipe 2 connected to the air pressure regulator 1. The suction pipe 2 includes an outer heat preservation pipe and an inner liquid storage pipe; the heat preservation pipe is a vacuum interlayer A double-layer pipe, a closed heat preservation chamber 21 is arranged between the heat preservation pipe and the liquid storage pipe, and the heat preservation chamber 21 is filled with a cold storage medium; the liquid storage pipe includes a sample chamber 22 above and a spiral capillary pipette 23 below, and the sample The lower part of the chamber 22 gradually shrinks and communicates with the upper end of the capillary pipette 23, and the lower end of the capillary pipette 23 is also connected with the metal suction nozzle 24, which is fixedly connected with the heat preservation tube; the air chamber 14 of the air pressure regulator 1 communicates with the upper pa...

Embodiment 2

[0029] like figure 1 and image 3 As shown, the difference between this embodiment and embodiment 1 is that the air pressure regulator 1 of embodiment 2 adopts another technical solution: wherein the air pressure regulator 1 includes a cylindrical air pipe 11, and the air pipe 11 is provided with a nozzle and a The pressing piece 12 with matching lumen size, the rubber sealing ring is set on the contact surface between the pressing piece 12 and the tube wall, the pressing piece 12 is connected with the bottom of the trachea 11 through the elastic rod 13, the bottom of the trachea 11 is provided with a through hole to communicate with the sample chamber 22, the trachea 11 A semi-permeable membrane 3 is also provided at the connection position with the sample cavity 22 . When in use, the pressing sheet 12 is pressed down, and then the pressing sheet 12 is released. Due to the action of the elastic rod 13, the pressing sheet 12 is bounced up, and the air chamber 14 sucks the mil...

Abstract

The invention belongs to the technical field of body fluid sampling devices, and particularly relates to a milk sampler for a modern pasture. The sampler consists of a gas pressure regulator and a suction pipe, wherein a closed heat-preserving cavity is formed in the suction pipe; the heat-preserving cavity is filled with a cold storage medium; a sample cavity is formed in the heat-preserving cavity; the lower side of the sample cavity is communicated with a spiral capillary suction pipe; the lower end of the capillary suction pipe is further communicated with a metal suction nozzle; the metalsuction nozzle is fixedly connected with the capillary suction pipe; a semi-permeable diaphragm is arranged at a junction of a gas cavity of the gas pressure regulator and the sample cavity. When thesampler is used, the cold storage medium in the heat-preserving cavity can perform cold storage and heat preservation on a sample in the sample cavity and can freeze a part of the sample in the capillary suction pipe, so that the sample does not leak, and thus the sampler has a good sealing effect. The sampler is reusable, easy to operate and relatively low in using cost.

Description

technical field [0001] The invention belongs to the technical field of body fluid sampling devices, in particular to a milk sampler for modern pastures. Background technique [0002] Modern pasture is a new method of large-scale animal husbandry. It uses modern facilities to realize intensive breeding of livestock, raises livestock in pens to feed feed and forage, and realizes mechanized slaughter and milking. This farming method has a high resource utilization rate and a high output rate of milk and meat products, which can meet people's growing food demand. [0003] This kind of modern pasture also has its own defects. Due to the intensive breeding method, the disease infection rate of livestock is high, and it is prone to outbreaks of epidemic diseases. Large quantities of drugs and antibiotics are used in pasture management. [0004] In some modern dairy farms, in order to resist livestock diseases, dairy farms need to conduct regular physical examinations for livestoc...
