[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Example 1

[0041] like Figure 1 and Figure 2As shown, a urine collection cup includes: a cup body 11 having a urine collection chamber 12 and a collection tube 13 communicating with the urine collection chamber 12; the cup body 11 is a thin-walled conical structure with the bottom surface facing upwards; the cup body 11 is provided with a urine inlet located at its upper end and communicating with the urine collection chamber 12 and a urine outlet 16 located at its lower end and communicating with the urine collection chamber 12; the collection tube 13 is fixedly connected to the outer wall of the cup body 11; the inlet of the collection tube 13 is higher than its outlet, and the inlet of the collection tube 13 is located above the horizontal plane of the urine outlet 16; a collection port 17 communicating with the urine collection chamber 12 is opened on the side wall of the cup body 11, the collection tube 13 is connected to the urine collection chamber 12 through the collection port 17, and the urine outlet 16 is configured such that its urine outflow is less than the urine inflow into the urine collection chamber 12.

[0042] As another embodiment of the present invention, it also includes a urinary tube 14, which is located below the urinary outlet 16, and the inlet of the urinary tube 14 is connected to the urinary outlet 16.

[0043] Furthermore, the urinary catheter 14 includes an inlet section, a storage section, and an outlet section, with the storage section located between the inlet and outlet sections. The minimum inner diameter of the inlet section is not less than the maximum inner diameter of the storage section, and the minimum inner diameter of the storage section is not less than the maximum inner diameter of the outlet section. This arrangement allows the initial urine to quickly enter the urinary catheter 14 and be temporarily stored in the inlet section and / or the storage section, before being discharged from the outlet of the urinary catheter 14, effectively preventing the initial urine from mixing with the midstream urine. It should be noted that the outlet section of the urinary catheter 14 is the outlet of the urinary catheter 14.

[0044] Conversely, if the inner diameter of the inlet section of the urinary catheter 14 is smaller than the inner diameter of the temporary storage section and / or the outlet section, the flow rate of the initial urine out of the cup 11 will be reduced. As the intermediate urine accumulates in the cup 11, some of the initial urine will mix with the intermediate urine and enter the collection tube 13, affecting the quality of the collected intermediate urine.

[0045] It should be noted that the inlet section and the storage section of the urinary catheter 14 can be the same section of tubing without distinction, serving both the function of initial urine intake and temporary storage. In other words, the inlet section and the storage section of the urinary catheter 14 can be tubing of the same specification with the same inner diameter, serving both the function of initial urine intake and temporary storage.

[0046] Preferably, the minimum inner diameter of the outlet section of the urine tube 14 is in the range of 1-5 mm, which allows the initial urine to be discharged smoothly while ensuring that the middle urine in the urine collection cup can accumulate to the collection tube position, thereby achieving effective collection of the middle urine.

[0047] In another embodiment of this utility model, a urine collection cup further includes a gripping part 15 fixedly connected to the cup body 11. The gripping part 15 is fixedly connected to the side wall of the cup body 11 and can be selected from various structures that can be gripped by the person being tested. For example, the gripping part 15 can be a sheet-like structure, a columnar structure, a spherical structure, a ring-shaped structure, etc.

[0048] Preferably, the gripping part 15 is a sheet-like structure that is fixedly connected to the upper edge of the cup body 11.

[0049] In use, the person being tested urinates into the urine collection chamber 12 of the cup body 11. The initial urine, under the influence of gravity, first enters the bottom of the urine collection chamber 12 and is quickly discharged from the urine outlet 16 into the urine outlet tube 14. Some of the initial urine is temporarily stored in the inlet and storage sections of the urine outlet tube 14, while some of the initial urine is discharged through the outlet section of the urine outlet tube 14. As the urine volume increases, the amount of midstream urine in the urine collection chamber 12 gradually increases, the liquid level gradually rises, and rises to the collection port 17, where it is discharged from the collection tube 13. The midstream urine is then collected using a corresponding collection device.

[0050] Example 2

[0051] This embodiment is a midstream urine collection device, including a urine collection cup 10 and a midstream urine collection device 20. The specific structure of the urine collection cup 10 is the same as in Embodiment 1.

[0052] Specifically, the midstream urine collection device 20 includes a collection tube 22 and a connector 21; the connector 21 is detachably fixed to the collection tube 22; the collection tube 22 is detachably fixed to the urine collection cup 10 via the connector 21.

[0053] In this embodiment, the connector 21 is at least partially fitted onto the outer circumference of the collection tube 22; the connector 21 is threadedly connected to the port of the collection tube 22. The arrangement of the connector 21 on the outer circumference of the collection tube 22 creates an overlap area between the two in the radial direction of the collection tube 22, thereby effectively shortening the overall length of the midstream urine collection device 20.

[0054] The connector 21 includes a connecting body 211, a connecting part 215, a flow part 214, a first receiving cavity 212, a second receiving cavity 219, and an exhaust hole 217 for venting gas from the collection tube 22 when collecting midstream urine; the connecting body 211, the connecting part 215, and the flow part 214 are arranged collinearly; the maximum outer diameter of the connecting part 215 is smaller than the inner diameter of the collection tube 22; the flow part 214 is provided with a flow cavity 216 that extends through it along its axial direction.

[0055] The connecting body 211 is sleeved on the outside of the connecting part 215; the upper end of the connecting part 215 is fixedly connected to the connecting body 211; the second receiving cavity 219 is located between the connecting body 211 and the connecting part 215; the wall thickness of the second receiving cavity 219 is greater than the wall thickness of the collecting test tube 22; the vent 217 at least partially penetrates the connecting body 211 axially and communicates with the second receiving cavity 219; the inner wall of the connecting body 211 is provided with an internal thread for connecting to the port of the collecting test tube 22.

[0056] Additionally, it should be noted that the vent 217 needs to be located close to the connector 215. When the connector 21 is threadedly connected to the collection tube 22, the vent 217 can communicate with the inside of the collection tube 22, ensuring that the gas inside the collection tube 22 is effectively discharged, thereby ensuring that the midstream urine can smoothly enter the collection tube 22.

[0057] The connecting part 215 is sleeved on the outside of the flow part 214; the lower part of the flow part 214 is fixedly connected to the connecting part 215; the first receiving cavity 212 is located between the flow part 214 and the connecting part 215; the wall thickness of the first receiving cavity 212 is adapted to the wall thickness of the collection tube 22.

[0058] In another embodiment of the present invention, the connector 21 also includes a cover for sealing it.

[0059] Furthermore, a flexible plastic strip is provided between the cover and the connecting body 211. The cover, the connecting body 211 and the flexible plastic strip are integrally formed. The cover is connected to the connecting body 211 under the action of the flexible plastic strip.

[0060] Example 3

[0061] Example 3 is the same as Example 2. The only difference is the specific configuration of the midstream urine collection device 20.

[0062] In this embodiment, as Figure 8 and Figure 9 As shown, the midstream urine collection device 20 includes a collection tube 22, a connector 21, and an anti-backflow elastic membrane 23 for sealing the port of the collection tube 22.

[0063] An anti-backflow elastic membrane 23 is installed at the end of the collection tube 22, including an elastic membrane body 231 and a sealing surface 232 fixedly connected to the elastic membrane body 231; the sealing surface 232 is provided with a split slit 233 for the insertion of the collection tube 13. Since the anti-backflow elastic membrane 23 is made of elastic material, the sealing surface 232 is in a closed state when no external force is applied. When the anti-backflow elastic membrane 23 is subjected to external force, especially when the elastic membrane body 231 is penetrated by the collection tube 13, the sealing surface 232 cracks at the split slit 233, allowing the collection tube 13 to penetrate the anti-backflow elastic membrane 23, and effectively preventing the collection tube 22 from falling under the action of friction.

[0064] Preferably, the anti-backflow elastic membrane 23 is made of rubber or silicone material.

[0065] Preferably, the split seam 233 is a cutting line arranged radially along the sealing surface 232.

[0066] Furthermore, the split seam 233 has three cutting lines arranged radially along the sealing surface 232, starting from the center of the sealing surface 232. The three split seams 233 have the same length, and the included angle between adjacent split seams 233 is set at equal angles.

[0067] The connector 21 includes a connecting body 211 and a flow cavity 216; the flow cavity 216 extends axially through the connecting body 211; the inner wall of the connecting body 211 is provided with an internal thread for connecting to the port of the collection tube 22, thereby achieving a detachable and fixed connection between the port of the collection tube 22 and the connector 21. Furthermore, the contact between the connecting body 211 and the port of the collection tube 22 secures the anti-backflow elastic membrane 23, preventing it from falling off.

[0068] In another embodiment of this utility model, the connector 21 further includes a cover 221 for sealing it. The cover 221 is connected to the connecting body 211 via a flexible connecting strip 223.

[0069] Furthermore, the lower surface of the cover 221 is provided with a sealing protrusion 222 adapted to the upper port of the flow cavity 216, which is used to seal the upper port of the flow cavity 216 to achieve double sealing and prevent leakage of urine sample.

[0070] In another embodiment of this utility model, the upper end of the connecting body 211 is also provided with a positioning opening 220, and the cover 221 is provided with a positioning area corresponding to the position of the positioning opening 220, which effectively improves the sealing accuracy and sealing efficiency of the cover 221.

[0071] Furthermore, a limiting block 224 is also provided on the cover 221. After the cover 221 is closed, the limiting block 224 can make close contact with the outer wall of the connecting body 211, effectively preventing the cover 221 from loosening after it is closed.
