Description

Deep sampling device for cloaca swab of poultry Technical Field The invention relates to the technical field of medical equipment for poultry, in particular to a deep sampling device for a cloaca swab of poultry. Background In the work of preventing, controlling and monitoring fowl epidemic diseases, sampling of the mucous membrane tissue in the deep part of cloaca is a key link of pathogen detection. At present, a common sampling tool is a cotton swab, and the swab is manually inserted into the cloaca of poultry during operation, and a mucous membrane sample is obtained through scraping. However, the existing sampling mode has the defects that firstly, natural bending exists between a cloaca and an intestinal tract, a traditional swab is of a straight rod structure, the traditional swab is difficult to conform to a bending channel to reach a deep target area, the contact between a sampling head and a mucous membrane is insufficient, the sampling success rate is low, especially, the sampling success rate is very obvious when a deep cell sample needs to be acquired, secondly, the sampling process is that the swab head is always exposed to the outside or a non-target cavity area in the inserting and withdrawing stages, pollution is easy to occur or the sample falls off in advance, the accuracy and the reliability of a detection result are affected, thirdly, after the sampling is completed, the swab head is manually sheared or directly put into a sampling tube, and the sample is easy to suffer from secondary pollution in the operation process. Disclosure of Invention The invention aims to provide a deep sampling device for a cloaca swab of a poultry, which aims to solve the problems that in the existing operation, the sampling depth is uncontrollable, a bending channel is difficult to conform, and a sample is easy to pollute.
