Description

Technical Field

[0001] This invention relates to the field of medical testing equipment technology, and in particular to a segmented midstream urine collection cup. Background Technology

[0002] Urinalysis is a commonly used testing method. Due to testing requirements, midstream urine is the most valuable for diagnosis, therefore, it is generally necessary to collect midstream urine. Currently, hospitals use a plastic cup as the container for urinalysis, requiring the examinee to distinguish between the midstream and foremilk urine and collect the midstream urine into the container. However, examinees often lack the relevant professional knowledge and are prone to mixing the foremilk and midstream urine during the process, causing cross-contamination and affecting the final test results.

[0003] To address these issues, some urine collectors have emerged on the market that can automatically distinguish and collect midstream urine. However, after successfully collecting midstream urine, these collectors have limited capacity, requiring patients to constantly monitor the liquid level. If the level is too high and urine is about to overflow, patients will instinctively try to stop the flow to prevent potential contamination. However, patients may not be able to stop the flow immediately, and interrupting the flow midway could cause some damage to the urinary system.

[0004] If the urine collector is removed when it is almost full, the urine may splash out during the movement of the collector, whether it flows onto the patient's hands or the surrounding ground, causing environmental pollution. Summary of the Invention

[0005] To address the technical problem of urine overflowing from midstream urine collectors in existing technologies, this invention provides a segmented midstream urine collection cup.

[0006] Therefore, the present invention provides the following technical solution: A segmented midstream urine collection cup includes a cup body and a test tube. The bottom of the cup body has a pre-stream urine collection box containing a pre-stream urine collection chamber. A float is placed inside the pre-stream urine collection chamber. The upper side wall of the pre-stream urine collection box has a pre-stream urine collection hole, the diameter of which is smaller than the diameter of the float. A gap exists between the side wall of the pre-stream urine collection box and the inner side wall of the cup body. A partition connects the edge of the upper side wall of the pre-stream urine collection box to the inner side wall of the cup body, and the partition has an overflow hole. The lower side wall of the cup body, below the overflow hole, has a midstream urine collection hole. The test tube is detachably connected to the cup body at the position corresponding to the midstream urine collection hole. The side wall of the pre-stream urine collection box, the inner side wall of the cup body, and the partition together form an overflow chamber. A downstream urine discharge hole is opened on the side wall of the bottom of the cup body corresponding to the overflow chamber, and this discharge hole communicates with the overflow chamber.

[0007] Furthermore, the cup body includes an upper cup body and a lower cup body. The outer side of the upper cup body is provided with a limiting strip, and the inner side of the lower cup body is provided with a limiting groove that engages with the limiting strip. The partition and the upper side wall of the front urine collection box body together constitute the bottom wall of the upper cup body.

[0008] Furthermore, the test tube has a detachable cap at the mouth.

[0009] Furthermore, at the bottom of the cup body, below the middle urine collection hole, there is a connecting tube, and at the bottom of the connecting tube, there is a through hole; a thin film is attached to the upper side of the lid, and at the center of the lid below the thin film, there is a puncture hole, through which the connecting tube can be inserted.

[0010] Furthermore, a locking block is provided at the root of the connecting pipe, and the top edge of the cover extends upward to form a locking groove that matches the locking block.

[0011] Furthermore, the bottom of the cup body and the periphery of the connecting tube are provided with arc-shaped walls, which can be engaged with the lid.

[0012] Furthermore, a handle is provided at the top of the cup body.

[0013] Advantages and positive effects of the present invention: The automatic float-based sealing mechanism achieves strict separation of the first and second urination streams, effectively preventing impurities in the first urination stream from contaminating the second urination stream sample. This ensures that the collected second urination stream sample has higher purity, providing a more reliable basis for subsequent medical testing.

[0014] The overflow chamber ensures that the urine can be discharged smoothly, preventing urine from accumulating and overflowing in the cup, thus maintaining hygiene and cleanliness during use; the compact layout of each structure also makes the collection cup of moderate size, making it easy to carry and store.

[0015] It integrates the functions of pre-void urine collection, mid-void urine collection and post-void urine discharge, requiring no additional operating steps or auxiliary tools. Users can complete the entire sample collection process during natural urination, simplifying the operation and making it especially suitable for people with limited mobility or weak operating ability.

[0016] The test tube and the cup are detachably connected, allowing the test tube to be easily removed for sealing, labeling, and testing after midstream urine collection, thus avoiding the risk of spillage during sample transfer. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] This invention provides a segmented midstream urine collection cup, such as... Figure 1 and Figure 4 As shown, the device includes a cup body 1 and a test tube 2. The bottom of the cup body 1 has a pre-collection urine box 5, which contains a pre-collection urine chamber 6. A float 7 is placed inside the pre-collection urine chamber 6. A pre-collection urine hole 8 is located on the upper side wall of the pre-collection urine box 5. The diameter of the pre-collection urine hole 8 is smaller than the diameter of the float 7. There is a gap between the side wall of the pre-collection urine box 5 and the inner side wall of the cup body 1. The edge of the upper side wall of the pre-collection urine box 5 is connected to the inner side wall of the cup body 1. A partition 9 is connected to the cup body 1, and an overflow hole 10 is provided on the partition 9. A middle urine collection hole 11 is provided on the lower side wall of the cup body 1, below the overflow hole 10. The test tube 2 is detachably connected to the cup body 1 at the position corresponding to the middle urine collection hole 11. The side wall of the front urine collection box 5, the inner side wall of the cup body 1, and the partition 9 together form an overflow cavity 12. A rear urine discharge hole 3 is provided on the side wall of the bottom of the cup body 1 corresponding to the overflow cavity 12. The discharge hole is connected to the overflow cavity 12.

[0031] When urine enters the cup 1, the initial portion of urine flows into the initial urine collection chamber 6 through the initial urine collection hole 8 on the upper side wall of the initial urine collection box 5. As the initial urine accumulates, the float 7 inside the collection chamber gradually rises due to buoyancy until it comes into contact with the initial urine collection hole 8. Utilizing the characteristic that the diameter of the float is larger than the diameter of the collection hole, the collection hole is automatically sealed, preventing subsequent urine from entering the initial urine collection chamber 6, thus completing the collection and isolation of the initial urine. After the initial urine collection hole 8 is sealed, the subsequent midstream urine, unable to enter the initial urine collection chamber 6, flows along the internal space of the cup 1 and finally flows into the detachably connected test tube 2 through the midstream urine collection hole 11 on the lower side wall of the cup 1, achieving precise collection of the midstream urine. After the midstream urine collection is completed, the subsequent urine will enter the overflow cavity 12 formed by the side wall of the front urine collection box 5, the inner side wall of the cup 1 and the partition 9 through the overflow hole 10 on the partition 9. Then, it will be discharged from the cup 1 through the downstream urine discharge hole 3 at the bottom of the cup 1, which corresponds to the overflow cavity 12, thus completing the drainage treatment of the downstream urine.

[0032] The top of the cup body 1 is equipped with a handle 4.

[0033] For the first embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the cup body 1 is a one-piece molded structure. At the bottom of the cup body 1, below the middle urine collection hole 11, there is a connecting tube 13. The bottom of the connecting tube 13 has a through hole 18. The test tube 2 has a cap 20 installed at its opening via a threaded removable method. A thin film is attached to the upper side of the cap 20, and a piercing hole 22 is located at the center of the cap 20, below the film, through which the connecting tube 13 can pass. A locking block 19 is provided at the base of the connecting tube 13, and the top edge of the cap 20 extends upward to form a locking groove 21 that matches the locking block 19. An arc-shaped wall 14 is provided at the bottom of the cup body 1 and around the connecting tube 13, which can engage with the cap 20.

[0034] After the midstream urine flows out through the midstream urine collection hole 11 on the lower side wall of the cup body 1, it will be guided along the internal structure of the cup body to the connecting tube 13 at the bottom, and then enter the test tube 2 through the through hole 18 at the bottom of the connecting tube. When assembling the test tube 2 with the cup body 1, the test tube 2 with the cap 20 must first be connected and fixed to the cap 20 by threads. At this time, the film on the upper side of the cap 20 can temporarily seal the mouth of the test tube to avoid external contamination. During assembly, the connecting tube 13 of the cup body 1 is aligned with the puncture hole 22 in the center of the lid 20 and inserted into the hole. As the connecting tube 13 is inserted, its bottom punctures the membrane on the lid 20, allowing the midstream urine to flow smoothly into the test tube 2 through the through hole 18. At the same time, the locking block 19 at the base of the connecting tube 13 precisely engages with the locking groove 21 formed by the upward extension of the top edge of the lid 20. Combined with the engagement of the arc-shaped wall 14 around the connecting tube 13 at the bottom of the cup body 1 and the lid 20, a double fixation is achieved between the test tube 2 and the cup body 1, ensuring a stable connection between the two during urine collection and preventing urine leakage due to shaking.

[0035] After the midstream urine collection is completed, the test tube 2 and the cap 20 are removed from the connecting tube 13 together. At this time, the cap 20 is still installed on the test tube 2 by threads. Although the membrane is punctured, it can still block the urine in the test tube 2, which is convenient for subsequent sample preservation and testing. The entire assembly and disassembly process is convenient.

[0036] For the second embodiment, as Figure 2 , Figures 5-8 As shown, the cup body 1 includes an upper cup body 15 and a lower cup body 16. The outer side of the upper cup body 15 is provided with a limiting strip 17, and the inner side of the lower cup body 16 is provided with a limiting groove that engages with the limiting strip 17. The partition 9 and the upper side wall of the front urine collection box 5 together constitute the bottom wall of the upper cup body 15.

[0037] The cup body 1 consists of an upper cup body 15 and a lower cup body 16, which are detachably connected by a limiting strip 17 engaging with a limiting groove. This connection method ensures the structural stability of the upper and lower cup bodies after assembly and facilitates disassembly for cleaning or replacement of parts after use. Simultaneously, the precise engagement of the upper cup body 15 and lower cup body 16 ensures the airtightness of the entire internal space of the cup body, preventing urine leakage from the connection gaps during flow and ensuring the orderly collection and distribution of urine. Furthermore, this split structure facilitates the maintenance and repair of key components inside the cup body, such as the front urine collection box 5 and the partition 9, improving the product's practicality and durability.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
