Description

An uninterrupted segmented urine collector Technical Field

[0001] The present invention relates to the field of medical devices, in particular to an uninterrupted segmented urine collector. Background Art

[0002] Urinalysis is a commonly used test method. Due to the test requirements, midstream urine testing has the greatest diagnostic value, so in principle, midstream urine needs to be collected. Currently, the container used for urine tests in hospitals is a plastic cup, and the examinee needs to master the distinction between midstream urine and front urine and collect the midstream urine into the container. However, the examinee lacks relevant professional knowledge and is very likely to mix front urine with midstream urine during the operation, causing cross contamination and affecting the final test results.

[0003] In order to solve the above problems, some urine collectors that can automatically distinguish and collect midstream urine have appeared on the market. However, after successfully collecting midstream urine, these midstream urine collectors require patients to pay attention to the liquid level in the collector at all times due to the limited volume of the collector itself. If the liquid level is too high and urine is about to overflow from the collector, the patient will subconsciously cut off the urine to prevent possible contamination caused by urine overflow. However, on the one hand, the patient may not be able to cut off the urine immediately, and on the other hand, cutting off the urine midway may cause a certain degree of damage to the human urinary system.

[0004] If the collector is removed when the urine is almost full, the collector will shake during movement, and the urine in it will easily splash out, either flowing onto the patient's hands or the surrounding ground, causing environmental pollution.

[0005] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes a urine collector with a simple structure and ingenious design, which can automatically separate the front urine and mid-stream urine to ensure that the mid-stream urine can be accurately obtained, while allowing the patient to urinate uninterruptedly during the collection process.

[0008] The bottom of the collection cup body 1 is also provided with a test tube connecting assembly, which includes a partition 10. Above the partition 10 is an overflow space 11 formed by a circle of side walls. A double-body tube is connected to the partition 10, and the double-body tube consists of a drain pipe 12 and an exhaust pipe 13. The top opening of the drain pipe 12 is opened on the partition 10, and 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 level. The exhaust port protection protrusion 8 is located above the top opening of the exhaust pipe 13. Below the partition 10 is a cylindrical socket 14. The inner diameter of the socket 14 matches the outer diameter of the end 19 of the test tube 15. When the end 19 is inserted into the socket 14, the bottom of the exhaust pipe 13 and the drain pipe 12 are both located in the test tube 15.

[0009] A liquid discharge port 16 is provided on the side wall of the collecting cup body 1 and is located at the bottom of the collecting cup body 1 . The liquid discharge port 16 and the socket 14 are located on both sides of the collecting cup body 1 , respectively.

[0010] A window 17 is formed on the side wall of the socket 14 .

[0011] Two symmetrically distributed guide plates 18 are provided in the overflow chamber 3 . The guide plates 18 are located on both sides of the drain port 16 and are cambered.

[0012] A sealing ring 20 is provided on the inner wall of the end head 19 , the inner diameter of the sealing ring 20 matches the maximum outer diameter of the double-body tube, and a plurality of sector-shaped rubber sheets 21 are provided in the sealing ring 20 , and the plurality of sector-shaped rubber sheets 21 together form a disc shape.

[0013] A handle 22 is hinged at the top edge of the collection cup body 1, and a limit plate 23 is provided at the root of the handle 22. The limit plate 23 and the handle 22 are perpendicular to each other. A limit block 24 matching the limit plate 23 is provided on the outer side of the top edge of the collection cup body 1, and symmetrically distributed limit plate buckles 25 are provided on both sides of the limit block 24.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This non-stop segmented urine collector has a simple structure, ingenious design, and reasonable layout. Conventional urine collectors require patients to control and adjust the device to obtain midstream urine, which often results in inaccurate midstream urine collection, affecting test results. Furthermore, when the urine collection is full, patients must either move the device (which may cause urine to spill and contaminate the environment) or cut off the urine flow themselves (which can affect the patient's health). Both methods present certain problems. To address these issues, this device incorporates a dual-layer structure within the cup. Urine entering the cup first fills the lower anterior urine cavity, and then the midstream urine is guided by the upper structure into a test tube for storage. When the test tube is full, the urine flows directly into the overflow chamber and is discharged directly from the overflow chamber. During this process, the patient does not need to move the device or cut off the urine flow themselves; they simply release urine continuously to collect midstream urine. Compared to conventional urine collectors, this device requires no patient intervention, making it a user-friendly, "foolproof" device. It can also effectively prevent urine overflow from polluting the patient and the surrounding environment. At the same time, its production 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.

[0029] The bottom of the collection cup body 1 is also provided with a test tube connecting assembly, which includes a partition 10. Above the partition 10 is an overflow space 11 formed by a circle of side walls. A double-body tube is connected to the partition 10, and the double-body tube consists of a drain pipe 12 and an exhaust pipe 13. The top opening of the drain pipe 12 is opened on the partition 10, and 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 level. The exhaust port protection protrusion 8 is located above the top opening of the exhaust pipe 13. Below the partition 10 is a cylindrical socket 14. The inner diameter of the socket 14 matches the outer diameter of the end 19 of the test tube 15. When the end 19 is inserted into the socket 14, the bottom of the exhaust pipe 13 and the drain pipe 12 are both located in the test tube 15.

[0030] A liquid discharge port 16 is provided on the side wall of the collecting cup body 1 and is located at the bottom of the collecting cup body 1 . The liquid discharge port 16 and the socket 14 are located on both sides of the collecting cup body 1 , respectively.

[0031] A window 17 is formed on the side wall of the socket 14 .

[0032] Two symmetrically distributed guide plates 18 are provided in the overflow chamber 3 . The guide plates 18 are located on both sides of the drain port 16 and are cambered.

[0033] A sealing ring 20 is provided on the inner wall of the end head 19 , the inner diameter of the sealing ring 20 matches the maximum outer diameter of the double-body tube, and a plurality of sector-shaped rubber sheets 21 are provided in the sealing ring 20 , and the plurality of sector-shaped rubber sheets 21 together form a disc shape.

[0034] A handle 22 is hinged at the top edge of the collection cup body 1, and a limit plate 23 is provided at the root of the handle 22. The limit plate 23 and the handle 22 are perpendicular to each other. A limit block 24 matching the limit plate 23 is provided on the outer side of the top edge of the collection cup body 1, and symmetrically distributed limit plate buckles 25 are provided on both sides of the limit block 24. The limit plate buckles 25 can undergo elastic deformation.

[0035] A positioning groove 26 is provided on the bottom end surface of the end of the handle 22, and a handle buckle 27 is provided at the top edge of the collection cup body 1. The handle buckle 27 matches with the positioning groove 26, and the handle buckle 27 can be elastically deformed. When the handle buckle 27 is clamped on the positioning groove 26, the handle 22 crosses the top opening of the collection cup body 1.

[0036] The volume of the anterior urinary cavity 2 is 5-15 ml.

[0037] The contour of the top edge of the upper cover 5 matches the contour of the inner wall of the collection cup body 1 .

[0038] A limiting ring 28 is provided below the bottom surface of the upper cover 5 . The limiting ring 28 can be plugged into the top opening of the anterior urinary cavity 2 , and the bottom edge of the limiting ring 28 is retracted inward.

[0039] The working process of the uninterrupted segmented urine collector of the embodiment of the present invention is as follows: when it is necessary to collect mid-stream urine for testing and examination, the patient pulls the handle 22 and pulls it to the outside of the collection cup body 1 and to a state perpendicular to the collection cup body 1, and holds the handle 22 to place the collection cup body 1 at the lower body excretion port, and the urine first enters the upper cover 5. Since the top edge of the upper cover 5 is tightly attached to the inner wall of the collection cup body 1, it can play a role in diversion, and all the urine entering the collection cup body 1 is introduced into the front urine cavity 2 below through the circular hole 6 opened on the bottom surface thereof, that is, the urine preferentially enters the front urine cavity 2. The volume of the front urine cavity 2 is 5-15 ml, which is the average amount of front urine. Therefore, after the front urine cavity 2 is filled with urine, the subsequent urine is mid-stream urine;

[0040] The liquid level in the front urinary cavity 2 continues to rise, and the float 4 therein also rises accordingly. When the float 4 contacts the circular hole 6, since the outer diameter of the float 4 is larger than the diameter of the circular hole 6, the float 4 can close the circular hole 6. At this time, the front urinary cavity 2 is closed, and 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 flows into the overflow space 11 above the partition 10, and then enters the test tube 15 plugged into the socket 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 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 urine will not block the exhaust pipe 13.

[0041] When the liquid level in the test tube 15 rises to the bottom opening of the drainage tube 12, urine cannot enter the test tube 15. At this time, the test tube 15 is filled with the collected midstream urine. The liquid level in the overflow space 11 gradually rises. When the liquid level is higher than the side wall forming the overflow space 11, it will overflow from here into the overflow chamber 3 below. Since the drainage port 16 is connected to the overflow chamber 3, this part of the urine will be discharged directly through the drainage port 16. Since a guide plate 18 is provided at the drainage port 16, the urine will be discharged smoothly under the action of the guide plate 18 instead of dripping down along the outer wall of the collection cup body 1. This structure is also to prevent environmental pollution.

[0042] That is to say, when the patient uses the collector to collect midstream urine, he does not need to remove the collector or stop urinating in the middle, but only needs to release urine into the collection cup 1 continuously, and finally midstream urine can be obtained;

[0043] After urination, the test tube 15 is pulled out of the socket 14 and the collection cup 1 is discarded. The socket 14 is not a complete cylinder, and a window 17 is opened on its side wall. This window 17 allows the socket 14 to have a certain elastic deformation ability to ensure that it can be firmly connected to the test tube 15, and allows the patient to observe the liquid level in the test tube 15 through the window 17.

[0044] 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, the plurality of sector-shaped rubber sheets 21 are attached to the outer wall of the double-tube body. This structure allows the double-tube body to be inserted into the test tube 15 while ensuring a seal inside the test tube 15.

[0045] In order to facilitate storage and transportation when not in use, the handle 22 in the 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 clamped on the handle buckle 27 at the top edge of the collection cup body 1. At this time, the handle 22 extends across the top opening of the collection cup body 1; in this state, the handle 22 can also play a certain supporting role to prevent the collection cup body 1 from deformation.

[0046] When it is necessary to use this collector to collect midstream urine, pull the handle buckle 27, and after the handle 22 regains its freedom, rotate it until the handle 22 rotates to the outside of the collection cup body 1, until the limit plate 23 and the limit block 24 contact each other. At this time, the limit plate buckle 25 is clamped on both ends of the limit plate 23, locking the handle 22. At this time, the handle 22 and the collection cup body 1 are relatively fixed, and the patient can hold the handle 22 to collect urine.
