[0033] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0034] As Figures 1 - 4As shown in the figure, this embodiment provides a rat urine collection device, which includes a cage 1, a funnel 2, a centrifuge tube connecting cylinder 3, and a filter tip 4. The cage 1 is located above the funnel 2, and the bottom surface of the cage 1 has a plurality of screening holes. The filter tip 4 is tubular. The outlet of the funnel 2 is fixedly connected and communicated with the upper end of the filter tip 4. The centrifuge tube connecting cylinder 3 is sleeved outside the filter tip 4 and fixedly connected to the funnel 2. The centrifuge tube connecting cylinder 3 has a clamping portion.

[0035] The rat urine collection device of this embodiment is a simple device, which can be used for long-term collection or one-time urine collection. For one-time urine collection, the device is simple and easy to clean, and can complete the urine collection of multiple rats within a short time.

[0036] The screening holes are arranged at the bottom of the cage 1, which can ensure that feces remain in the cage, and urine can smoothly pass through the screening holes to reach the funnel 2 below, and finally converge at the filter tip 4 for further finer filtration and flow into the centrifuge tube below for temporary storage.

[0037] The centrifuge tube connecting cylinder 3 is used to connect the centrifuge tube 100 through the clamping portion. The centrifuge tube 100 is firmly connected and not easy to fall off. An approximately closed space is formed between the funnel 2, the centrifuge tube connecting cylinder 3 and the centrifuge tube, reducing urine pollution during the collection process, ensuring the freshness of the collected rat urine, reducing urine evaporation, and avoiding sample collection errors.

[0038] Optionally, the cage 1 is rectangular parallelepiped or cylindrical. In one specific example, as Figure 2 shown, in order to better adapt to the shape of the funnel 2, the cage 1 is a cylinder with the same diameter as the upper end of the funnel 2, avoiding rat urine leaking outside the funnel 2. More specifically, the diameter of the cage 1 is 45 cm.

[0039] Specifically, the outer diameter of the filter tip 4 is smaller than the inner diameter of the conventional centrifuge tube 100.

[0040] Specifically, the clamping portion is an annular protrusion or an annular groove provided on the inner wall of the centrifuge tube connecting cylinder 3. The centrifuge tube connecting cylinder 3 is fixedly clamped with the upper end of the centrifuge tube 100, and its connection method is the same as or similar to the connection method between the centrifuge tube lid and the centrifuge tube 100. Urine is directly collected into the centrifuge tube 100, preparing for further centrifugation to obtain the supernatant sample, which is convenient and fast.

[0041] On the basis of any of the above solutions, there are a plurality of centrifuge tube connecting cylinders 3. The centrifuge tube connecting cylinders 3 are cylindrical, and the diameters of the plurality of centrifuge tube connecting cylinders 3 are all different and coaxially arranged.

[0042] In existing collection devices, the urine collection specifications are fixed, and the collector cannot be replaced according to the type of urine collected (24-hour urine; morning urine, etc.). Moreover, most collection devices have their own specified collectors, which increases errors and makes cleaning difficult.

[0043] In this embodiment, centrifuge tube connecting cylinders 3 with different diameters are provided for connecting with centrifuge tubes of different diameters or capacities, so as to adapt to centrifuge tubes for collecting disposable urine and 24-hour urine.

[0044] In one specific example, as Figure 4 shown, there are two centrifuge tube connecting cylinders 3, which are respectively used to connect with centrifuge tubes 100 of 15 ml and 50 ml.

[0049] On the basis of any of the above solutions, the mounting rack 5 further includes a second support ring 53. One side of the second support ring 53 is slidably connected and positioned with the vertical rod 51. The second support ring 53 is located below the first support ring 52. The funnel 2 is located within the second support ring 53.

[0050] The height of the second support ring 53 is adjustable and is used to support the funnel 2.

[0051] Specifically, the funnel 2 is in an inverted conical shape. The inner diameter of the second support ring 53 is smaller than the diameter of the upper end of the funnel 2. The funnel 2 is positioned with the second support ring 53 through the conical structure.

[0052] Specifically, a second slider is fixed on one side of the second support ring 53. The second slider is slidably engaged with the vertical rod 51. The second locking bolt is threadedly connected to the second slider, and its end abuts against or releases the vertical rod 51, so as to position or release the second slider.

[0053] Based on any of the above solutions, a filter screen is further included, and the upper end of the filter tip 4 is covered with the filter screen.
