Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically a urine sampling device for obstetric and gynecological testing. Background Technology

[0002] As one of the core disciplines of clinical medicine, obstetrics and gynecology undertakes important responsibilities such as women's reproductive health management, pregnancy and childbirth monitoring, and prevention and treatment of gynecological diseases. Traditional urine sampling devices mostly use simple containers to collect naturally excreted urine samples. Their design focuses on basic leak prevention and sterile preservation, but they have obvious limitations when dealing with complex physiological states (such as women's menstrual periods).

[0003] During menstruation, menstrual blood and shed endometrial fragments can easily mix into urine. While these fragments themselves generally don't directly affect chemical indicators in routine urinalysis, such as protein, glucose, and pH, red blood cells in menstrual blood can cause false positives for blood occult blood (BLD). Similarly, white blood cells may be incorrectly interpreted as a symptom of urinary tract infection. Normally, urinalysis doesn't actively remove these endometrial fragments, but centrifugation removes sediment, and the supernatant is analyzed for more accurate results. Excessive endometrial fragments can cloud the urine sample, affecting instrument readings; therefore, improvements and optimizations are needed. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a urine sampling device for obstetric and gynecological testing, which solves the problems that menstrual blood and endometrial fragments may cause false positives for occult blood and misjudgment of white blood cells in urine tests of women during menstruation, and that too many fragments may affect the accuracy of the readings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a urine sampling device for obstetric and gynecological testing, comprising a collector, a filter screen fixedly installed on the inner wall of the middle part of the collector, an installation bucket threadedly installed at the bottom of the collector, a funnel fixedly installed inside the installation bucket, a second strainer fixedly installed on the inner wall of the bottom of the funnel, a urine collection bottle disposed below the funnel, and a corrugated tube fixedly installed on the outer wall of the funnel, the other end of the corrugated tube extending out of the installation bucket.

[0006] Preferably, a soft rubber pad is fixedly installed on the top of the collector, and an L-shaped handle is fixedly installed on the outer wall of the collector.

[0007] Preferably, the filter screen is designed to be inclined inside the collector, and the inclined direction of the filter screen is opposite to the inclined direction of the inner wall of the collector it contacts.

[0008] Preferably, a Y-shaped rod is fixedly installed on the top outer wall of the mounting barrel, and the Y-shaped rod is engaged with the corrugated pipe.

[0009] Preferably, the bottom outer wall of the funnel is provided with several semi-circular grooves, and the top of the urine collection bottle is fixedly installed with several cylinders.

[0010] Preferably, the semicircular grooves and cylinders are equidistantly distributed with the axis of the urine collection bottle as the center, and the semicircular grooves are respectively adapted to the corresponding cylinders.

[0011] Preferably, the bottom of the mounting bucket is provided with a bottom cover, and a hollow column is fixedly installed on the top of the bottom cover. The hollow column is threadedly connected to the mounting bucket, and the urine collection bottle is placed inside the hollow column and rotatably connected to the hollow column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention achieves dual filtration of urine by setting up a filter screen one and a strainer screen two. The filter screen one can initially filter out larger foreign objects, while the strainer screen two further filters the urine a second time, which can efficiently remove impurities and foreign objects in the urine, improve the quality of urine collection, obtain more accurate test results, and reduce the risk of misdiagnosis or misjudgment caused by sample contamination or interference from impurities.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 7 As shown, this utility model provides a urine sampling device for obstetric and gynecological testing. A filter screen 102 is fixedly installed on the inner wall of the middle part of the collector 1. An installation bucket 2 is threadedly installed at the bottom of the collector 1. A funnel 3 is fixedly installed inside the installation bucket 2. A second filter screen 302 is fixedly installed on the inner wall of the bottom of the funnel 3. A urine collection bottle 4 is arranged below the funnel 3. A corrugated tube 301 is fixedly installed on the outer wall of the funnel 3. The other end of the corrugated tube 301 extends out of the installation bucket 2. A soft rubber gasket 103 is fixedly installed on the top of the collector 1. An L-shaped handle 101 is fixedly installed on the outer wall of the collector 1. The filter screen 102 is designed to be inclined inside the collector 1. The inclined direction of the filter screen 102 is opposite to the inclined direction of the inner wall of the collector 1 it contacts. A Y-shaped rod 201 is fixedly installed on the outer wall of the top of the installation bucket 2. The Y-shaped rod 201 is engaged with the corrugated tube 301.

[0024] The filter screen 102 is designed with an inclined shape, and its inclined direction is opposite to the inclined direction of the inner wall of the collector 1 it contacts. This increases the contact area between the urine and the filter screen 102, improves the filtration efficiency, and allows the urine to be filtered more thoroughly during the flow process.

[0025] like Figure 6 As shown, a number of semicircular grooves 303 are provided on the bottom outer wall of the funnel 3, and a number of cylinders 401 are fixedly installed on the top of the urine collection bottle 4. The semicircular grooves 303 and cylinders 401 are distributed at equal distances with the axis of the urine collection bottle 4 as the center, and the semicircular grooves 303 are respectively matched with the corresponding cylinders 401.

[0026] The matching design of the semi-circular groove 303 and the cylinder 401 allows the urine collection bottle 4 to be easily combined with or separated from the funnel 3 when needed, and prevents it from shifting, so as to ensure that the urine can flow smoothly into the urine collection bottle 4. It also makes the urine collection bottle 4 more stable when fixed and less likely to fall off due to shaking.

[0027] like Figure 5 , Figure 7 As shown, the bottom of the installation bucket 2 is provided with a bottom cover 5, and a hollow column 501 is fixedly installed on the top of the bottom cover 5. The hollow column 501 is threadedly connected to the installation bucket 2, and the urine collection bottle 4 is placed inside the hollow column 501 and rotatably connected to the hollow column 501.

[0028] The threaded connection between the hollow column 501 and the mounting bucket 2, and the rotatable connection between the urine collection bottle 4 and the hollow column 501, allow the bottom cover 5 to be easily unscrewed or tightened, thus facilitating the installation and removal of the urine collection bottle 4. When taking urine samples, users can simply rotate the bottom cover 5 to fix or remove the urine collection bottle 4, greatly simplifying the operation process.

[0029] Working principle and usage process of this utility model:

[0030] Before use, first install the collector 1 and the installation bucket 2. With the bottom of the installation bucket 2 facing upward, align the cylinder 401 with the semi-circular groove 303 so that the urine collection bottle 4 is inserted into the installation bucket 2. Then, align the hollow column 501 on the bottom cover 5 with the urine collection bottle 4. Rotate the bottom cover 5 to rotate the hollow column 501. By rotating the bottom cover 5, the urine collection bottle 4 is fixed in the middle between the funnel 3 and the bottom cover 5. Attach the corrugated tube 301 to the Y-shaped rod 201.

[0031] During use, the patient holds the L-shaped handle 101 and presses the soft rubber pad 103 tightly against the urinary organ to prevent urine from splashing or overflowing. First, the urine is filtered through the filter screen 102, allowing larger foreign objects to enter the mounting container 2. Under gravity, the urine flows naturally into the funnel 3 and then undergoes secondary filtration through the filter screen 302 at the bottom of the funnel 3. The filtered urine then enters the urine collection bottle 4. After collection, if there is excessive urine, remove the corrugated tube 301 to drain the excess urine. Finally, rotate the bottom cover 5 with the opening of the collector 1 facing upwards to separate the bottom cover 5 and the urine collection bottle 4 inside the hollow column 501 from the mounting container 2, and then remove the urine collection bottle 4.
