Description

Technical Field

[0001] This utility model relates to the field of pharmacokinetic experimental technology, specifically to a fecal and urine separation and collection structure for a rodent metabolic cage. Background Technology

[0002] Pharmacokinetic and bioanalytical experiments are crucial steps in drug development. They investigate the absorption, distribution, metabolism, and excretion of drugs in the body, elucidating the relationship between drug dosage, in vivo drug concentration, and drug effects. This provides a basis for the clinical application of drugs. By collecting urine, feces, and bile from animals, the content of drugs and their metabolites is measured, and the excretion rate and pathway are calculated. This helps determine whether drugs are primarily excreted through the kidneys or bile, and the kinetics of excretion, providing a reference for the formulation of clinical drug use regimens.

[0003] In some existing rodent metabolic cages, feces and urine are collected separately. During this separation, the lower end of the rodent metabolic cage is fitted with two layers of partitions. An inclined metal or plastic screen facilitates feces collection, while urine flows through the screen holes into the lower layer.

[0004] The existing fecal and urine separation and collection structures for rodent metabolic cages have the following problems: when separating and collecting feces and urine, the inclined guide plate does not guide and collect all the feces, and a small amount of feces will stick to the upper part of the guide plate, which will need to be collected manually, which is inconvenient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a feces and urine separation and collection structure for a rodent metabolic cage. When separating and collecting feces and urine, the feces on the guide plate are automatically scraped off, preventing feces from sticking to the upper end of the guide plate. It is convenient to use and can effectively solve the problems in the background art.

[0028] The working principle of this utility model is as follows:

[0029] When separating and collecting rodent feces and urine, first open the iron gate 13, then drive the rodents into the interior of the fence 2 through the inclined ladder 8, then close the iron gate 13. When the iron gate 13 is closed, the fixing buckle 14 will be inserted between the two buckles 15. Then, the pin 16 will be inserted between the fixing buckle 14 and the buckles 15. The rodents will produce a large amount of feces and urine inside the fence 2. The feces and urine will fall to the upper end of the guide plate 4.

[0030] Next, the operation of motor 711 is controlled by the control switch group 12. The output shaft of motor 711 drives the left sprocket 712 to rotate. The left sprocket 712 will drive the right sprocket 712 to rotate through the transmission chain 713. The rotation of sprocket 712 will drive the lead screw 714 to rotate. The rotation of lead screw 714 will drive the threaded slider 72 to move forward inside the slide groove 6. In turn, it will drive the scraper 74 to move forward through the rotating shaft 73. In turn, it will scrape the feces and urine at the upper end of the guide plate 4 forward, so that the feces and urine are scraped into the collection tank 5.

[0031] When feces and urine enter the collection tank 5, the feces are blocked on the upper surface of the screen 9. Then the urine falls to the upper end of the guide block 10 and is discharged from the discharge port 11 along the guide block 10. When the scraper 74 moves to the front end of the guide plate 4, the rear side of the upper end of the support rod 752 pushes the support rod 752 to rotate, and the scraper 74 will tilt forward.

[0032] Next, the motor 711 is rotated counterclockwise by the control switch group 12, which in turn moves the scraper 74 to the rear end of the guide block 10. Then, the gear 753 contacts the two-thirds gear 754. Then, by controlling the control switch group 12, the motor 755 operates. The output shaft of the motor 755 drives the pin to rotate, which in turn drives the two-thirds gear 754 to rotate. The rotation of the two-thirds gear 754 drives the scraper 74 to rotate through the meshing gear 753. When the scraper 74 is rotated to the point where it is blocked by the stop lever 756, the above steps are repeated to collect feces and urine.

[0033] It is worth noting that the motor 711 and motor 755 disclosed in the above embodiments can be Y180L-615 for motor 711 and YJ61 for motor 755. The control switch group 12 is provided with a switch button that corresponds to motor 711 and motor 755 and is used to control their switching operation.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
