Description

[Detailed description of the invention] This invention is designed to feed and water experimental animals such as mice and rats kept in the breeding room of a breeding device, and to separate and color the excrement excreted by the experimental animals. The present invention relates to a urine collection device for collecting urine in an experimental breeding device for animals.

This type of experimental breeding equipment allows laboratory animals such as mice to be raised in a breeding room, and their intake of food and water is measured, as well as feces and urine, which are separated and measured. It is something to do.

As shown in Fig. 4, the conventional urine collection device of this type of experimental equipment has a trumpet at the top inside the urine tube B of the excrement and urine separator A, which is detachably fitted into the funnel part (not shown) of the breeding room. A feces tube C having a shaped opening C' is arranged concentrically, and a urinary drain tube D is provided protruding from the urinary tube B, and a urine collection bottle E is slid onto the lower end of the urinary drain tube D. In the figure, F is a feces collection bottle detachably attached to the lower end of the feces tube C by rubbing or the like.

Therefore, when using this device to take out the urine in the urine collection bottle E, it is necessary to remove the urine collection bottle E from the urinary downflow tube D and attach another urine collection bottle to the tube D, which makes the operation complicated and time-consuming. Additionally, there was a risk that urine might leak when replacing the bottle.

Furthermore, depending on the experiment, tests may be required at certain intervals or after each urination, but with conventional urine collection devices, the urine collection bottle E must be filled with urine for each of these tests. The urine in the urine collection bottle E must be collected after it is removed from the downflow tube D, and therefore it is not suitable for these tests.

The present invention focuses on the above-mentioned points, and its main object is to provide a urine collection device that can remove urine from a urine collection container while the container is attached to the urinary downflow tube.

Another main object of the present invention is to provide a urine collection device in which the urine collection container is attached to the urinary downflow tube, and the urine in the urine collection container can be easily removed using a dropper or the like.

Therefore, as a means to achieve the above-mentioned purpose, the present invention is designed to feed and water experimental animals in the breeding room.
In an experimental breeding apparatus for animals in which excreted excrement and urine can be separated and collected separately, a urinary downflow tube is provided protruding from the urinary tube of the feces and urine separator installed at the bottom of the breeding room. The device is characterized in that the middle portion of the urine collection tube, which has an opening at the top and a narrow urine collection tube at the bottom, is detachably attached.

The bait is stored in the bait container 29 and closed with the lid 31, and the bait container 29 is closed.
is fitted into the fitting tube 28.

Therefore, the experimental animal a in the breeding chamber 1 inserts its neck into the feeding chamber 18, takes food from the feeding port 30, and eats it in the feeding chamber 25.

At this time, the dropped bait is collected from the bait collecting pipe 26 into the bait collecting bin 27.

Drinking water is obtained in the water supply chamber 18 by attaching the mouth to the end port 22 a of the water supply pipe 20 and suctioning it, and spilled water is collected from the water collection pipe 22 into the water collection bottle 23 .

Therefore, the amount of food ingested by the experimental animal a is determined by the difference between the amount initially placed in the food container 29 and the total amount of food remaining in the food container 29 and food in the food collecting bin 27. You can measure it by pulling it, and you can also measure the amount of water sampled in the same way.

On the other hand, the excrement and urine excreted by the experimental animals falls into the funnel 2 from the grid-like floor 4, is spread by the urine spreader 5, and impinges on the inclined surface of the funnel 2.

The liquid urine flows down along the slopes of the rows 1 and 2, passes from the tube wall of the urine tube 7 of the excrement separator 6, passes through the urine downflow tube 9, and is collected into the urine collection tube 12.

Furthermore, since the excrement is solid, it rolls on the inclined wall surface of the funnel 2, falls from the lower end opening, and is collected into the collection bin 10 from the upper end opening 8a of the excrement tube 8 of the excrement separator 6.

Therefore, various analyzes etc. are performed using this feces and urine, and the feces are removed by removing the feces collection bottle 10 from the joint part 8b.
Remove it, insert a dropper, etc. from that part, and take it out by suctioning.

It should be noted that the above-mentioned breeding device is merely an example thereof, and it goes without saying that the water supply means and feeding means of this breeding device may have any other structure.
