Description

Technical Field

[0001] The invention relates to the technical field of collection devices, in particular to a semi-automatic visualized sheep rumen fluid collection device. Background Art

[0002] Rumen fluid contains a large number of microorganisms required for ruminant digestion. It is an important experimental sample for establishing an in vitro fermentation model for ruminants and analyzing microbial communities. When conducting animal experiments, it is necessary to extract rumen fluid in order to accurately understand the digestion of feed in the rumen, the dynamic changes of feed microorganisms on the rumen fluid microbial community, and the fermentation of silage in the rumen.

[0003] At present, the general steps for extracting sheep rumen fluid can be divided into:

[0004] Restraining the sheep: Before rumen fluid extraction can be performed, the sheep needs to be secured and stabilized. Restraining usually involves using ropes or a restraining rack to restrict the movement of the sheep to prevent injury to the sheep or the operator during the procedure.

[0005] Sheep head fixation and rumen tube insertion: The sheep head is fixed to ensure that the rumen tube can be accurately inserted into the rumen. The rumen tube is a special soft tube designed to be inserted into the rumen through the mouth. The operator needs to have certain skills and experience to avoid causing unnecessary harm to the sheep.

[0006] Manual fixation after rumen tube insertion: Once the rumen tube is successfully inserted, it needs to be manually fixed to prevent it from sliding out. This usually involves using ropes or clamps to secure the tube to the sheep's head or neck.

[0007] Large syringe to collect rumen fluid: Using a large syringe to extract rumen fluid can ensure that a sufficient sample volume is collected while reducing disturbance to the sheep. During the extraction process, the operator needs to be careful not to inhale too much air to avoid affecting the quality of the sample and the analysis results.

[0008] There are the following problems in collecting rumen fluid using the above method:

[0009] During the rumen fluid collection process, the rumen tube needs to be manually fixed to prevent the sheep from chewing and swallowing the rumen tube, or the sheep resists during the extraction process, causing the end of the rumen tube to shift, resulting in the end of the rumen tube being unable to immerse in the rumen fluid, and the rumen fluid cannot be extracted or the sample is unevenly collected.

[0010] During the collection process, manually pulling the syringe to extract rumen fluid is extremely laborious, and there is air in the syringe during the extraction process, making it inconvenient to observe the syringe scale to reflect the volume of rumen fluid extracted, which affects work efficiency.

[0011] Therefore, it is necessary to provide a semi-automatic visual sheep rumen fluid collection device to solve the above problems. Summary of the invention

[0012] The purpose of the present invention is to provide a semi-automatic visualized sheep rumen fluid collection device, which has the advantages of conveniently fixing the rumen tube and conveniently extracting rumen fluid, and solves the problems of inconvenience in fixing the rumen tube and inconvenience in extracting rumen fluid.

The collection tube on the side is opened and closed by a clamp to collect rumen fluid. The two openings at different heights on the upper end of the outer wall of the sampling tube are used. The lower opening is connected to the collection tube through a connecting tube to extract the rumen fluid; the higher opening is connected to the vacuum pump through a connecting tube to assist suction. Observe the scale on the outer wall of the sampling tube, record the volume of rumen fluid extracted, and ensure that an appropriate amount of sample is collected.

[0027] Preferably, the first fixing belt and the second fixing belt are both designed with Velcro material, and the end of the first fixing belt facing away from the bite tube passes through a limiting ring.

[0028] The first fixing belt and the second fixing belt are made of Velcro material, which provides the ability of quick fixing and removal, simplifying the installation process of the device.

[0029] Preferably, the outer wall of the sampling tube is printed with scales, and the two openings on both sides of the upper end of the outer wall of the sampling tube are at different heights, the connecting tube connected to the lower opening is connected to the collection tube, and the connecting tube connected to the higher opening is connected to the vacuum pump.
