[0036] Reference Figure 1 and Figure 2 The embodiment of the utility model provides a urine filtering and collecting device, which includes a urine separator 1, a urine receiving tube 2 and a floating member 3;

[0037] The urine separator 1 comprises a main pipe 11 and a urine inlet pipe 12 arranged on the outer circumference of the main pipe 11 and connected to the main pipe 11; the lower end of the main pipe 11 is open and can be connected to the pipe opening of the urine receiving tube 2;

[0038] The floating member 3 includes a float column 31 and a ball plug 32 arranged at the lower end of the float column 31; the float column 31 is slidably arranged in the main pipe 11; the ball plug 32 is arranged in the urine receiving tube 2 located at the lower end of the main pipe 11; the outer diameter of the float column 31 is smaller than the maximum outer diameter of the ball plug 32; the floating member 3 can float on the surface of urine and rise with the urine surface to the ball plug 32 to block the opening at the lower end of the main pipe 11.

[0039] Combination Figure 1 and Figure 2 When the above device is in use, in the initial state, there is no urine in the urine receiving tube 2, the lower end of the float column 31 extends into the urine receiving tube 2, and the ball plug 32 falls to the bottom of the urine receiving tube 2; after the urine is poured into the main pipe 11 from the urine inlet pipe 12, the urine falls into the urine receiving tube 2 at the lower end of the main pipe 11 from the gap between the float column 31 and the main pipe 11, the gap between the float column 31 and the urine receiving tube 2, and the gap between the ball plug 32 and the urine receiving tube 2 under the action of gravity; as the urine liquid level in the urine receiving tube 2 continues to rise, the floating member 3 also continues to rise with the urine surface until the ball plug 32 blocks the opening at the lower end of the main pipe 11 (refer to Figure 3), at this time, the urine in the urine receiving tube 2 is collected completely, and the urine cannot fall from the opening at the lower end of the main pipe 11.

[0040] In the process of collecting urine using the device provided by the present application, since the outer diameter of the float column 31 is smaller than the maximum outer diameter of the ball plug 32, the urine can be filtered to a certain extent in the process of falling into the urine receiving tube 2 from the gap between the ball plug 32 and the urine receiving tube 2; and the floating member 3 plays a certain sealing role in the urine collection process, which can prevent the urine from being contaminated; in addition, when the amount of urine collected reaches the required amount, the ball plug 32 will block the opening at the lower end of the main pipe 11, so that the urine cannot continue to flow into the urine receiving tube 2, thereby realizing the quantitative collection of urine.

[0041] In order to improve the stability and sealing of the connection between the main pipe 11 and the urine receiving tube 2, in this embodiment, the lower end of the main pipe 11 can be inserted into and screwed to the urine receiving tube 2; specifically, the lower end of the main pipe 11 is provided with an external thread, and the internal thread at the pipe mouth of the urine receiving tube 2 is used to realize the threaded connection between the two.

[0042] Continue to refer to Figure 2 The floating member 3 is a hollow structure. The hollow configuration can minimize the gravity of the floating member 3, so that the floating member 3 can float on the urine better.

[0043] On the basis of the above structure, the upper end of the float column 31 is open, and the opening periphery of the upper end of the float column 31 is folded outward to form an annular flange 33. On the basis of the above structure, the urine inlet pipe 12 is arranged between the annular flange 33 and the lower end opening of the main pipe 11. The annular flange 33 can block the gap between the main pipe 11 and the float column 31, further improving the sealing performance during the urine collection process.

[0044] Reference Figure 3 , the ball plug 32 includes a first part, a second part and a third part connected in sequence from top to bottom; wherein the first part and the second part are cylindrical, and the diameter of the first part is smaller than the diameter of the second part, and the third part is hemispherical; the upper end of the first part is connected to the float 31, and the outer diameters of the first part and the second part and the ball diameter of the third part are larger than the outer diameter of the float 31. The lower end of the main pipe 11 is provided with a first through hole and a second through hole connected to each other, wherein the first through hole is arranged above the second through hole, and the aperture of the first through hole is smaller than the aperture of the second through hole and the diameter of the second part. When the ball plug 32 moves to the first part and is inserted into the first through hole and the second part is inserted into the second through hole, since the aperture of the first through hole is smaller than the diameter of the second part, the ball plug 32 cannot continue to move upward, so the ball plug 32 and the lower end of the main pipe 11 form a fitting closed structure, thereby blocking the urine from flowing downward.

[0045] Reference Figure 4The inlet end of the urine inlet pipe 12 is provided with a trumpet-shaped expansion structure.

[0046] Reference Figure 4 and Figure 5 The urine filtering and collecting device further comprises a urine cup 4, the opening area of ​​which gradually increases from the first end of the urine cup 4 to the second end of the urine cup 4, and the first end of the urine cup 4 can be inserted into the urine inlet pipe 12; in this embodiment, the first end of the urine cup 4 is inserted into the expanded structure of the urine inlet pipe 12. The setting of the urine cup 4 further increases the urine inlet area of ​​the device, making it easier to collect urine.

[0047] Furthermore, the urine diverter 1 further comprises a urine diverter pipe 13 disposed on the outer peripheral surface of the main pipe 11 and connected to the main pipe 11. After the ball plug 32 blocks the opening at the lower end of the main pipe 11, urine entering the main pipe 11 is discharged from the urine diverter pipe 13.

[0048] Specifically, the urine inlet conduit 12 and the urine diversion conduit 13 are respectively arranged on opposite sides of the main conduit 11; the urine inlet conduit 12 is arranged to be inclined downward from the inlet of the urine inlet conduit 12 to the outlet of the urine inlet conduit 12, and the urine diversion conduit 13 is arranged to be inclined downward from the inlet of the urine diversion conduit 13 to the outlet of the urine diversion conduit 13, and the axis of the urine inlet conduit 12 and the axis of the urine diversion conduit 13 are roughly coincident. The above arrangement enables the urine in the urine inlet conduit 12 and the urine diversion conduit 13 to flow from the inlet to the outlet under the action of gravity; and after the ball plug 32 blocks the opening at the lower end of the main conduit 11, the urine in the urine inlet conduit 12 can flow smoothly into the urine diversion conduit 13.

[0049] Reference Figure 5 and Figure 6 , there are multiple urine dividers 1, and the multiple urine dividers 1 are connected in sequence;

[0050] In any two adjacent urine diverters 1 , the urine diversion pipe 13 of one urine diverter 1 is inserted into the urine inlet pipe 12 of the other urine diverter 1 .

[0051] Take two urine diverters 1 connected together as an example; during the urine collection process, urine flows into the first urine diverter 1 along the urine cup 4, and falls from the opening at the lower end of the main pipe 11 into the urine receiving pipe 2 connected to the lower end of the first urine diverter 1. When the urine in the urine receiving pipe 2 at the lower end of the first urine diverter 1 is collected, the ball plug 32 in the urine receiving pipe 2 blocks the opening at the lower end of the first urine diverter 1; the urine that continues to enter the first urine diverter 1 flows out from the urine diverting pipe 13, and flows into the second urine diverter 1 through the urine inlet pipe 12 on the second urine diverter 1. Through the above process, the volume of urine flowing into the urine receiving tube 2 at the lower end of each urine diverter 1 is determined, thereby indirectly quantifying the urine volume; at the same time, urine of different stages can be collected, for example, urine flowing into the urine receiving tube 2 at the lower end of the first urine diverter 1 is front urine, and urine flowing into the urine receiving tube 2 at the lower end of the second urine diverter 1 is mid-stream urine, thereby achieving the effect of filtering and collecting different urine segments; clinically, urine of different stages can detect different target substances in urine (different active substances in urine), and different detection purposes can be achieved by collecting urine of different stages.

[0052] In actual use, the number of urine dividers 1 connected in series can be reasonably set according to actual needs.

[0053] Reference Figure 7 The urine filtering and collecting device further comprises a urine receiving tube end cap 5, which is used to seal the tube opening of the urine receiving tube 2 filled with urine. After the urine is collected, the urine receiving tube 2 is sealed and stored by the urine receiving tube end cap 5.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
