Embodiment 1

[0093] A comparative study was conducted on the urination rate calculated by the animal urination function measuring device 1 according to Example 1 of the present invention and the conventional animal urination function measuring device 100 . The animal urination function measuring device 1 of Embodiment 1 of the present invention is the above-mentioned animal urination function measuring device of the embodiment of the present invention. The wire diameter of the fine mesh part 52 of the mesh part 5 is 0.06 mm, and the mesh size is about 1mm 2 . In the conventional animal urination function measuring device 100, the wire diameter of the mesh part 50 of the mesh part 50 is 0.5 mm, and the mesh size is about 3 mm. 2 . Furthermore, in the conventional animal urination function measurement device 100 , the injection part 60 is connected to the housing part 20 , but not connected to the extraction part 70 , and only the extraction part 70 is provided on the measurement part 80 ....

Embodiment 2

[0100] A comparative study was carried out between the intravesical pressure measurement using the animal voiding function measuring device 1 of Example 2 of the present invention and the conventional animal voiding function measuring device 100 . The urinary function measuring device 1 for animals according to the second embodiment of the present invention is the same as the urinary function measuring device for animals according to the first embodiment of the present invention described above. like Figure 6A and Figure 6B As shown, since the conventional animal urination function measurement device 100 is the animal urination function measurement device 1 described in Embodiment 1, description thereof is omitted.

[0101] Explain the research method. The same 12-week-old SD rats (Charles River, Japan) were used for the animal urinary function measurement device 1 of Example 2 of the present invention and the conventional animal urinary function measurement device 100 . ...

Embodiment 3

[0107] Using the urinary function measuring device 1 for animals in Example 3 of the present invention, a comparative study was conducted on the urination speeds of low-week-old rats (10-week-old) and high-week-old rats (26-month-old) during spontaneous urination. The animal urination function measuring device 1 according to the third embodiment of the present invention is the above-mentioned animal urination function measuring device according to the embodiment of the present invention.

[0108] Explain the research method. In the container 2 of the animal urination function measuring device 1 of Example 3 of the present invention, put 5 low-week-old rats (10 weeks old) and high-week-old rats (26 months old) respectively, and measure the natural function of the whole night. To urinate, calculate the urination rate from the obtained measurements, and conduct a comparative study. From all the urinations of five young rats housed in Housing Unit 2, select the urination point wi...

Abstract

Disclosed are a urinary function measuring device for animals and a urinary function measuring method for animals capable of sampling the amount of animal urine with high accuracy. Specifically disclosed is a urinary function measuring device which comprises an accommodating unit that accommodates an animal other than humans; a collecting unit that is disposed below the accommodating unit and collects urine discharged by the animal in the accommodating unit; a reticulated unit that is disposed below the accommodating unit, allows passage of the urine of the animal to the collecting unit, and collects objects other than the urine; a measuring unit that measures the weight of the urine collected by the collecting unit; and a data recording unit that records the data measured by the measuring unit. The diameter of the net of the reticulated unit is less than or equal to 0.5 mm, and the size of the mesh of the reticulated unit is more than or equal to 1 mm2 and less than or equal to the maximum mesh size determined by at least either the excretions of the animal accommodated in the accommodating unit or a predetermined object used for accommodating the animal in the accommodating unit.

Description

technical field [0001] The present invention relates to an animal urination function measuring device and an animal urination function measurement method for measuring the urination function of an animal such as urination volume and urination speed. Background technique [0002] In pharmacological research in the field of urology, etc., the urine volume and frequency of urination of animals are measured, and the measured data are used as indicators for investigating the health status of animals and the influence of pharmaceuticals. More specifically, in order to investigate the health status of animals and the effects of chemicals, it is necessary to measure the rate of urination as an index. Conventionally, for example, the amount of urine excreted in animals has been measured by visually checking changes in the amount of urine excreted into a graduated cylinder at regular intervals, which is extremely laborious. [0003] In order to solve the above-mentioned problems, an ...
