Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a portable 24-hour urine specimen collection device. Background Art

[0002] In the diagnosis of kidney diseases, the 24-hour urine protein quantitative test is an important examination item. Patients need to undergo this examination for a long time and frequently. The traditional urine collection method is to use a large container to collect all the urine discharged within 24 hours, measure the volume, then shake it well and take a part to the hospital for testing. This method requires patients to operate multiple times, record the time and urine volume of each urination, which increases the operation burden of patients and brings great inconvenience to their lives. Moreover, frequent manual recording is prone to errors and affects the accuracy of test results. In addition, urine collection devices are often bulky (barrels or basins), inconvenient to carry, and prone to urine contamination and deterioration. Once patients go out due to work or life reasons, urine preservation and carrying are extremely inconvenient, and it is easy to miss or misrecord, affecting the accuracy of test results;

[0003] Therefore, in view of the technical problems and defects of the traditional method, this solution proposes a portable 24-hour urine specimen collection device, which can, on the premise of ensuring that the specimen is not contaminated and deteriorated, simply and accurately record the 24-hour urine volume and collect the specimen, greatly simplify the process of this examination for patients and reduce the operation burden, and also increase the accuracy of the results.

[0033] A main weighing sensor 5 is arranged at the bottom of the hand collection outer shell 1, and a cover body 4 is arranged at the upper end;

[0034] A weighing bottom plate 9 is arranged at the bottom of the bracket 12, and a collection rack 11 is arranged at the upper end and is movably connected to the collection tank 25; the lower end of the weighing bottom plate 9 is fixedly connected to the main weighing sensor 5, and a collection sleeve 10 is arranged at the upper end and is detachably connected to the storage tank 13; a storage pull rod 14 is arranged on one side of the storage tank 13, and a storage cover 16 is arranged at the upper end; a storage handle 15 is arranged outside the storage pull rod 14; an opening and closing assembly is fixedly connected to the lower end of the storage cover 16; a collection cover 26 is arranged at the upper end of the collection tank 25;

[0035] The lower end of the collection tank 25 is conical, and a discharge port 27 is arranged at the bottom; a micro solenoid valve 7 is arranged inside the discharge port 27, and a battery pack 8 is arranged outside;

[0036] The lower end of the collection rack 11 is conical and is movably connected to the collection tank 25, and a sub-weighing sensor 6 is arranged at the bottom;

[0037] The collection housing 1 is provided with a display screen 2 on the outside and an operation panel 3 on the lower end;

[0038] The opening and closing assembly includes a fixed seat 17, a hexagonal slide 18, a slider 19, a sliding block 20, a sliding column 21, a knob 22, and an opening and closing slide 23; the fixed seat 17 is fixedly connected to the storage cover 16, and the upper end is provided with a hexagonal slide 18 and six sliders 19 are arranged in a circumferential array; the bottom of the slider 19 is provided with a sliding block 20 slidably connected to the hexagonal slide 18, and the upper end is provided with a sliding column 21 slidably connected to the knob 22; six opening and closing slides 23 are arranged in a circumferential array on the knob 22 and are slidably connected to the sliding column 21;

[0039] A toggle opening 24 is provided on one side of the storage cover 16 to rotate the connection knob 22;

[0040] The storage cover 16, the knob 22, and the middle of the fixing seat 17 are provided with holes to cooperate with the discharge port 27 to discharge urine;

[0041] The volume of the collecting tank 25 and the storage tank 13 are both 500ml;

[0042] In this embodiment, when the device is in use, the storage tank 13 is fixed to the lower end of the bracket 12 through the collection sleeve 10, the collection tank 25 is placed on the collection rack 11, and the collection cover 26 is opened. The patient uses the collection tank 25 to collect urine, and the auxiliary weighing sensor 6 measures the single urine volume in real time, and the main weighing sensor 5 accumulates the total weight synchronously. After the urine is collected, the micro solenoid valve 7 is opened, and the urine is discharged into the storage tank 13 through the discharge port 27 according to a certain proportion. After a certain amount of urine is discharged, the micro solenoid valve 7 is closed, and the remaining urine can be discarded;

[0043] After each sample is divided, the device automatically records the single urine volume, sample volume and time node, accumulates and generates 24-hour total data, and updates the total volume in real time through the display screen 2, and displays the remaining storage space in the storage tank 13; if you go out for a short time, you can carry the collection tank 25 alone, go home after collecting urine, connect the device, and add the sample to the storage tank 13;

[0044] In this embodiment, the total urine volume and the single urine volume are automatically measured by dual weighing sensors. It is only necessary to operate the device to collect samples after urination, and there is no need to frequently record the urination time and urine volume, which simplifies the urine collection process and reduces the patient's operating burden; and by accurately measuring the urine weight and accumulating the data, the total urine volume data can be accurately obtained, avoiding the problem of inaccurate test results caused by manual recording errors in traditional methods; only an appropriate amount of samples are retained in the collection tank, and excess urine is discarded, which significantly reduces the volume of the urine collection device and is convenient to carry;

[0045] In this embodiment, by measuring the weight of urine, the urine density is: 1.010-1.030, at this time, according to the formula:

[0046]

[0047] That is

[0048]

[0049] the current urine volume can be calculated

[0050] In this embodiment, the retention ratio for each time is set through the operation panel 3, such as 1 / 10 or 1 / 15, so as to accurately control the discharge amount through the secondary weighing sensor 6 and the micro solenoid valve 7

[0051] Embodiment 2

[0052] As Figures 1-6 shown, a bracket 12 is arranged inside the collection housing 1; the lower end of the bracket 12 is movably connected to the storage tank 13, and the upper end is movably connected to the collection tank 25

[0053] A main weighing sensor 5 is arranged at the bottom of the hand collection housing 1, and a cover body 4 is arranged at the upper end

[0054] A weighing bottom plate 9 is arranged at the bottom of the bracket 12, and a collection rack 11 is arranged at the upper end and is movably connected to the collection tank 25; the lower end of the weighing bottom plate 9 is fixedly connected to the main weighing sensor 5, and a collection sleeve 10 is arranged at the upper end and is detachably connected to the storage tank 13; a storage pull rod 14 is arranged on one side of the storage tank 13, and a storage cover 16 is arranged at the upper end; a storage handle 15 is arranged outside the storage pull rod 14; a lower end of the storage cover 16 is fixedly connected to an opening and closing assembly; a collection cover 26 is arranged at the upper end of the collection tank 25

[0055] The lower end of the collection tank 25 is conical, and a discharge port 27 is arranged at the bottom; a micro solenoid valve 7 is arranged inside the discharge port 27, and a battery pack 8 is arranged outside

[0056] The lower end of the collection rack 11 is conical and is movably connected to the collection tank 25, and a secondary weighing sensor 6 is arranged at the bottom

[0057] A display screen 2 is arranged outside the collection housing 1, and an operation panel 3 is arranged at the lower end

[0058] The opening and closing assembly includes a fixed seat 17, a hexagonal chute 18, a slider 19, a sliding block 20, a sliding column 21, a knob 22, and an opening and closing chute 23; the fixed seat 17 is fixedly connected to the storage cover 16, and a hexagonal chute 18 is arranged at the upper end and six sliders 19 are arranged in a circumferential array; a sliding block 20 is arranged at the bottom of the slider 19 and is slidably connected to the hexagonal chute 18, and a sliding column 21 is arranged at the upper end and is slidably connected to the knob 22; six opening and closing chutes 23 are arranged in a circumferential array on the knob 22 and are slidably connected to the sliding column 21

[0059] A toggle opening 24 is provided on one side of the storage cover 16 to rotate the connection knob 22;

[0060] The volume of the collecting tank 25 and the storage tank 13 are both 500ml;

[0061] In this embodiment, the working principle of the opening and closing assembly is as follows: when the knob 22 is rotated, the opening and closing chute 23 drives the sliding column 21 to slide on the knob 22, thereby causing the slider 19 to move in the hexagonal chute 18; the movement of the slider 19 realizes the opening and closing action of the opening and closing assembly, thereby controlling the opening and closing of the storage cover 16, facilitating the collection and processing of urine specimens;

[0062] In this embodiment, the device only needs to rotate the knob 22 to complete the sealing, avoiding direct contact of the hand with the inside of the storage tank 13, and can achieve rapid opening and closing without the need to frequently remove the storage cover 16. The mechanical linkage of the hexagonal slide groove 18 and the slider 19 ensures that the six sides are evenly stressed when closed, and the sealing is strong.

[0063] Example 3

[0064] In this embodiment, since the urine specific gravity of different patients is different, in actual use, the urine specific gravity can be measured by a conventional test paper method. The test paper method for measuring urine specific gravity is a conventional existing technology, so the measurement operation process is not described;

[0065] In this embodiment, by measuring the specific value of urine specific gravity (SG), the corresponding urine density can be obtained according to the formula:

[0066] ρ 尿 =SG×ρ 水

[0067] And the density of water is about 1.000g / mL, so the above formula can be simplified to:

[0068] ρ 尿 =SG

[0069] The true volume of urine can then be calculated using the following formula:

[0070]

[0071] In this embodiment, by embedding the above formula in the device, the patient only needs to input the corresponding urine specific gravity measured to automatically calculate the actual volume of urine, thereby improving the measurement accuracy of the device.

[0072] In summary, the present invention simplifies the urine collection process by accurately measuring the urine weight and accumulating data, reduces the burden on patients for multiple operations and frequent manual recording of time and urine volume, improves convenience, and makes it easier for patients to cooperate in completing the examination; by using the method of accurately measuring the urine weight, the total urine volume data can be accurately obtained, avoiding the inaccurate test results caused by manual recording errors in the traditional method, and providing a more reliable basis for subsequent diagnosis;

[0073] Meanwhile, by only retaining an appropriate amount of specimen in the collection tank and discarding the excess urine, the volume of the urine collection device is significantly reduced, making it easier to carry whether the patient is moving in the hospital or traveling daily, improving the portability of the device; only retaining an appropriate amount of specimen reduces the sample volume, facilitates the preservation of the sample, reduces the risk of sample deterioration, better ensures the quality of the sample, and is conducive to subsequent test analysis;

[0074] Finally, by setting a micro solenoid valve 7 and a battery pack 8 at the discharge port 27 at the bottom of the collection tank 25, intelligent control of urine discharge is achieved. Combined with the display screen 2 and the operation panel 3 on the collection housing 1, it can be intuitively displayed and operated, improving the user-friendliness for patients.
