Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a continuous segmented urine collection device. 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 the aforementioned 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. 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.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] The present invention addresses the aforementioned shortcomings of the prior art by proposing a urine collection device that is simple in structure and ingenious in design, capable of automatically separating the first and second urination segments to ensure accurate acquisition of the second urination segment, while allowing the patient to urinate continuously during the collection process.

[0006] The technical solution of this invention is: a continuous segmented urine collector, comprising a collection cup 1, characterized in that: a front urine chamber 2 is provided at the bottom of the collection cup 1, the front urine chamber 2 is located in the middle of the collection cup 1, and an overflow chamber 3 is formed between it and the inner wall of the collection cup 1; a float 4 is provided in the front urine chamber 2; an upper cover 5 is provided above the front urine chamber 2; a circular hole 6 is provided at the bottom plate of the upper cover 5; the outer diameter of the float 4 is larger than the diameter of the circular hole 6; the side walls of the upper cover 5 form an upper cover space 7; an overflow port is provided at one end of the upper cover 5, and a vent protection protrusion 8 is provided at the overflow port. The bottom of the collection cup 1 is also provided with a test tube connection assembly, which includes a partition 10. Above the partition 10 is an overflow space 11 formed by a ring of side walls. A double-body tube is connected to the partition 10. The double-body tube consists of a drain pipe 12 and an exhaust pipe 13. The top opening of the drain pipe 12 is on the partition 10, while the top opening of the exhaust pipe 13 is higher than the partition 10. The bottom openings of the drain pipe 12 and the exhaust pipe 13 are at the same horizontal height. The exhaust port protection protrusion 8 is located above the top opening of the exhaust pipe 13. Below the partition 10 is a cylindrical insertion port 14. The inner diameter of the insertion port 14 matches the outer diameter of the end 19 of the test tube 15. When the end 19 is inserted into the insertion port 14, the bottom of the exhaust pipe 13 and the drain pipe 12 are both located inside the test tube 15. The side wall of the collection cup 1 is provided with a drain port 16 located at the bottom of the collection cup 1, and the drain port 16 and the insertion port 14 are respectively located on both sides of the collection cup 1.

[0007] A window 17 is provided on the side wall of the socket 14.

[0008] The overflow cavity 3 is provided with two symmetrically distributed guide plates 18, which are located on both sides of the drain port 16 and are arc-shaped.

[0009] A sealing ring 20 is provided on the inner wall of the end 19. The inner diameter of the sealing ring 20 matches the maximum outer diameter of the double tube. Multiple fan-shaped rubber sheets 21 are provided inside the sealing ring 20, and the multiple fan-shaped rubber sheets 21 together form a disc shape.

[0010] A handle 22 is hinged to the top edge of the collection cup 1. A limiting plate 23 is provided at the base of the handle 22. The limiting plate 23 and the handle 22 are perpendicular to each other. A limiting block 24 matching the limiting plate 23 is provided on the outer side of the top edge of the collection cup 1. A symmetrically distributed limiting plate buckle 25 is provided on both sides of the limiting block 24. The limiting plate buckle 25 can undergo elastic deformation.

[0011] A positioning groove 26 is provided on the bottom surface of the end of the handle 22, and a handle buckle 27 is provided at the top edge of the collection cup 1. The handle buckle 27 matches the positioning groove 26, and the handle buckle 27 can be elastically deformed. When the handle buckle 27 is locked on the positioning groove 26, the handle 22 extends across the top opening of the collection cup 1.

[0012] The volume of the anterior urinary cavity 2 is 5-15 ml.

[0013] The top edge of the cover 5 matches the inner wall contour of the collection cup 1.

[0014] A limiting ring 28 is provided below the bottom surface of the upper cover 5. The limiting ring 28 can be inserted into the top opening of the front urine cavity 2, and the bottom edge of the limiting ring 28 is drawn inward.

[0015] Compared with the prior art, the present invention has the following advantages: This type of uninterrupted segmented urine collector features a simple structure, ingenious design, and reasonable layout. Traditional urine collectors require patients to manually control and adjust the flow to obtain midstream urine, often resulting in inaccurate midstream urine collection and affecting test results. Furthermore, when the collection container is full, patients must either remove the collector (potentially spilling urine and contaminating the environment) or manually cut off the urine flow (potentially impacting their health), both methods presenting certain problems. To address these issues, this collector incorporates a double-layered structure within the cup. Urine entering the cup first fills the lower first-stage urine chamber, then the midstream urine is guided by the upper structure into a test tube for storage. Once the test tube is full, the urine flows into the overflow chamber and is directly discharged. During this process, patients do not need to move the collector or manually cut off the flow; they only need to continuously release urine to collect midstream urine. Compared to traditional collectors, it requires no patient intervention, making it a user-friendly and "foolproof" collector. Moreover, it can effectively prevent urine leakage from polluting the patient and the surrounding environment. At the same time, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. Attached Figure Description

[0022] The specific embodiments of the present invention will be described below with reference to the accompanying drawings: Figures 1 to 6 As shown, an uninterrupted segmented urine collector includes a collection cup 1. A front urine chamber 2 is located at the bottom of the collection cup 1, situated in the middle of the cup 1. An overflow chamber 3 is formed between the front urine chamber 2 and the inner wall of the cup 1. A float 4 is placed inside the front urine chamber 2. A top cover 5 is positioned above the front urine chamber 2. A circular hole 6 is formed on the bottom plate of the top cover 5. The outer diameter of the float 4 is larger than the diameter of the circular hole 6. The side walls of the top cover 5 enclose a top cover space 7. An overflow port is located at one end of the top cover 5, and a vent protection protrusion 8 is provided at the overflow port. The bottom of the collection cup 1 is also provided with a test tube connection assembly, which includes a partition 10. Above the partition 10 is an overflow space 11 formed by a ring of side walls. A double-body tube is connected to the partition 10. The double-body tube consists of a drain pipe 12 and an exhaust pipe 13. The top opening of the drain pipe 12 is on the partition 10, while the top opening of the exhaust pipe 13 is higher than the partition 10. The bottom openings of the drain pipe 12 and the exhaust pipe 13 are at the same horizontal height. The exhaust port protection protrusion 8 is located above the top opening of the exhaust pipe 13. Below the partition 10 is a cylindrical insertion port 14. The inner diameter of the insertion port 14 matches the outer diameter of the end 19 of the test tube 15. When the end 19 is inserted into the insertion port 14, the bottom of the exhaust pipe 13 and the drain pipe 12 are both located inside the test tube 15. The side wall of the collection cup 1 is provided with a drain port 16 located at the bottom of the collection cup 1, and the drain port 16 and the insertion port 14 are respectively located on both sides of the collection cup 1.

[0023] A window 17 is provided on the side wall of the socket 14.

[0024] The overflow cavity 3 is provided with two symmetrically distributed guide plates 18, which are located on both sides of the drain port 16 and are arc-shaped.

[0025] A sealing ring 20 is provided on the inner wall of the end 19. The inner diameter of the sealing ring 20 matches the maximum outer diameter of the double tube. Multiple fan-shaped rubber sheets 21 are provided inside the sealing ring 20, and the multiple fan-shaped rubber sheets 21 together form a disc shape.

[0026] A handle 22 is hinged to the top edge of the collection cup 1. A limiting plate 23 is provided at the base of the handle 22. The limiting plate 23 and the handle 22 are perpendicular to each other. A limiting block 24 matching the limiting plate 23 is provided on the outer side of the top edge of the collection cup 1. A symmetrically distributed limiting plate buckle 25 is provided on both sides of the limiting block 24. The limiting plate buckle 25 can undergo elastic deformation.

[0027] A positioning groove 26 is provided on the bottom surface of the end of the handle 22, and a handle buckle 27 is provided at the top edge of the collection cup 1. The handle buckle 27 matches the positioning groove 26, and the handle buckle 27 can be elastically deformed. When the handle buckle 27 is locked on the positioning groove 26, the handle 22 extends across the top opening of the collection cup 1.

[0028] The volume of the anterior urinary cavity 2 is 5-15 ml.

[0029] The top edge of the cover 5 matches the inner wall contour of the collection cup 1.

[0030] A limiting ring 28 is provided below the bottom surface of the upper cover 5. The limiting ring 28 can be inserted into the top opening of the front urine cavity 2, and the bottom edge of the limiting ring 28 is drawn inward.

[0031] The working process of the uninterrupted segmented urine collector of this invention is as follows: When it is necessary to collect midstream urine for testing, the patient pulls the handle 22 and moves it to the outside of the collection cup 1 and perpendicular to the collection cup 1. Holding the handle 22, the patient places the collection cup 1 at the lower body excretion opening. The urine first enters the upper cover 5. Since the top edge of the upper cover 5 is in close contact with the inner wall of the collection cup 1, it can play a guiding role. All the urine entering the collection cup 1 is introduced into the lower front urine cavity 2 through the round hole 6 opened on its bottom surface. That is, the urine preferentially enters the front urine cavity 2. The volume of the front urine cavity 2 is 5-15ml, which is the average amount of the front urine. Therefore, after the front urine cavity 2 is full of urine, the subsequent urine is the midstream urine. As the liquid level in the front section of the urine chamber 2 rises continuously, the float 4 also rises accordingly. When the float 4 comes into contact with the round hole 6, since the outer diameter of the float 4 is larger than the diameter of the round hole 6, the float 4 can seal the round hole 6. At this time, the front section of the urine chamber 2 is sealed, and the urine continues to enter the inner cavity of the upper cover 5. The liquid level in the inner cavity of the upper cover 5 gradually rises. When the liquid level reaches the height of the overflow port, it flows out through the overflow port and into the overflow space 11 above the partition 10. Then, it enters the test tube 15 inserted at the insertion port 14 through the drain pipe 12. During the above process, the air in the test tube 15 is discharged through the exhaust pipe 13 to ensure that the urine can smoothly enter the test tube 15. The exhaust port protection protrusion 8 is located above the top opening of the exhaust pipe 13 to ensure that the urine will not block the exhaust pipe 13. When the liquid level in test tube 15 rises to the bottom opening of drain tube 12, urine cannot enter test tube 15, and test tube 15 is filled with collected midstream urine at this time; the liquid level in overflow space 11 gradually rises, and when the liquid level is higher than the side wall forming overflow space 11, it will overflow from here to overflow cavity 3 below. Since drain port 16 is connected to overflow cavity 3, this part of urine will be discharged directly through drain port 16. Since a guide plate 18 is provided at drain port 16, the urine will be discharged smoothly under the action of guide plate 18, instead of dripping down along the outer wall of collection cup 1. This structure is also to prevent environmental pollution. In other words, when patients use this collector to collect midstream urine, they do not need to remove the collector or stop urinating. They only need to continuously release urine into the collection cup 1 to obtain midstream urine. After urination, pull the test tube 15 out of the inlet 14 and discard the collection cup 1. The inlet 14 is not a complete cylinder. A window 17 is provided on its side wall. This window 17 allows the inlet 14 to have a certain elastic deformation ability, ensuring that it can be stably connected to the test tube 15. It also allows the patient to observe the liquid level in the test tube 15 through the window 17. When the end 19 of the test tube 15 is inserted into the socket 14, the bottom of the exhaust pipe 13 and the drain pipe 12 (i.e. the lower half of the double tube body) are both located inside the test tube 15. At this time, multiple fan-shaped rubber sheets 21 are attached to the outer wall of the double tube body. This structure can both allow the double tube body to be inserted into the test tube 15 and ensure the seal inside the test tube 15. To facilitate storage and transportation when not in use, the handle 22 in this collector is designed to be movable. When not in use, the bottom surface of the handle 22 faces upward, and the positioning groove 26 at its end is engaged with the handle buckle 27 at the top edge of the collection cup 1. At this time, the handle 22 extends across the top opening of the collection cup 1. In this state, the handle 22 can also provide some support to prevent the collection cup 1 from deforming. When it is necessary to use this collector to collect midstream urine, pull the handle latch 27. After the handle 22 regains its degree of freedom, rotate it until the handle 22 is rotated to the outside of the collection cup 1, until the limiting plate 23 and the limiting block 24 are in contact with each other. At this time, the limiting plate latch 25 is locked at both ends of the limiting plate 23, locking the handle 22. At this time, the handle 22 and the collection cup 1 are relatively fixed, and the patient can hold the handle 22 to collect urine.
