Bovine exhaled breath collecting device and collecting method thereof

Abstract

The invention discloses a bovine exhaled breath collecting device and a collecting method thereof. The bovine exhaled breath collecting device comprises a feeding trough, the upper port of which is provided with a rubber ring. The shape of a central region surrounded by the rubber ring can fit the cow at the greatest extent so as to ensure that exhaled breath of the cow stays inside the feeding trough. A plurality of position detection sensors used for detecting whether a cow is in contact with the inner edge of the rubber ring are arranged on the inner edge of the rubber ring at the upper port of the feeding trough. When all the position detection sensors are triggered, it is considered that the cow's mouth fully fits the inner edge of the rubber ring, and it is through that the air exhaled by the cow will fully remain in the feeding trough. An air sampling device is arranged on the outer wall of the feeding trough. The bovine exhaled breath can be accurately collected, and the air iscollected in the sampling bag for subsequent more detailed analysis in a laboratory.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry inspection and quarantine devices, and in particular relates to a cattle exhaled gas collection device and a collection method thereof. Background technique [0002] The breath exhaled by a cow can reflect the health of the cow itself. For example, the breath exhaled by a cow with a normal smell has no peculiar smell. If the exhaled breath has a foul smell, it indicates that there may be necrosis in the lungs and respiratory tract; if there is a purulent smell , it indicates that there may be abscess rupture in the lungs; if there is acetone smell, it indicates that there may be ketosis, and so on. [0003] The above method through the sense of smell is only a preliminary judgment. If you want to further qualitatively judge the gas composition exhaled by cows, you need to further analyze it through experimental instruments (the common method is to use gas chromatography, for example: Jour...

AI Technical Summary

Problems solved by technology

[0005] 1. It adopts extensive detection, the gas exhaled by the cow is easy to diffuse, and the distance between the cow's mouth and the gas collection pipe will also affect the test results, so the accuracy of the test results cannot be guaranteed

[0006] 2. It uses online detection, that is, the gas concentration exhaled by cows is detected on-site by a gas detector. Due to the limitation of the sensor's own performance, it is impossible to conduct a more detailed analysis of the gas exhaled by cows.
