Description

Technical Field

[0001] The present invention relates to the technical field related to urine analysis, and in particular to a portable intelligent urine analyzer. Background Art

[0002] Urine testing is one of the three routine tests in modern clinical medicine. According to the composition of urine, the test report is output after calculation. In daily use, urine analyzers are divided into large urine analyzers and home portable urine analyzers;

[0003] There are certain deficiencies in the existing portable urine analyzers for home use. When urine is analyzed and tested, a test strip is usually inserted into the portable urine analyzer, and the insertion position is often wrong. Moreover, because the test strips are mostly made of soft materials, they are prone to bend and break during the insertion process.

[0004] In order to solve the above defects, reference can be made to the portable urine analyzer disclosed in the prior art (Chinese patent with application number CN202210913340.8 and publication date 2022-10-21). The analyzer takes out the test paper and the test paper holder after the urine is stained from the inside of the snap-in box, and inserts the test paper holder into the inside of the in-and-out slot. After the test paper holder is inserted into the inside of the in-and-out slot, the gear is driven to rotate by starting the drive motor. The rotation of the gear will cooperate with the rack to move the test paper holder into the inside of the bearing shell, so as to facilitate the insertion of the test paper for detection and avoid the phenomenon of the test paper breaking or insertion error during the insertion process.

[0005] And you can refer to the portable urine analyzer disclosed in the prior art (Chinese patent application number CN202010280493.4, published on June 19, 2020). The test strip holder and the detection head of the analyzer adopt a detachable plug-in structure, which can ensure the accurate placement of the test strip and facilitate the cleaning of the test strip holder. The front end of the test strip slot is set with an inclination angle that facilitates the test strip to slide in, which can simplify the test strip placement operation and improve the detection efficiency;

[0006] And a portable urine analyzer disclosed in the prior art (application number CN201610462350.9, published on August 24, 2016) is provided with a paper carrier belt for driving the test paper belt to be transported on the conveying device. The paper carrier belt drives the transmission of the test paper belt to realize batch sample inspection, and it is not necessary to test the test paper one by one, which is convenient to operate;

[0007] Although the above device can solve the problem of stably inserting the test strip into the analyzer, there are still certain shortcomings when using it. When collecting urine through the test strip, the patient usually puts the urine directly on the test strip, but some parts of the test strip may not be fully stained with urine, resulting in certain shortcomings in the detection process.

[0008] So we proposed a portable intelligent urine analyzer to solve the above problems. Summary of the invention

Embodiment 2

[0042] In order to solve the problem that urine analyzers currently on the market analyze urine with test strips, and patients usually urinate directly on the test strips to absorb urine, but the test strips may only be partially absorbed and may not be fully stained with urine. Figure 1 , Attachment Figure 2 and attached Figure 7 -Attached Fig. 9The bottom end of the urine collecting hopper 5 extends into the interior of the container body 1 and contacts the outer side of the upper end of the feed hopper 18, and the outer side of the feed hopper 18 is fixed to the upper part of the interior of the container body 1 through a fixed shaft 17. The bottom of the feed hopper 18 is connected to the embedded block 20 through a feed pipe 19. The bottom position of the embedded block 20 is connected to the top of the discharge pipe 22. The bottom position of the discharge pipe 22 extends into the interior of the analysis chamber 23. The bottom position of the discharge pipe 22 is directly above the test paper holder 29. A Tesla valve channel 21 for downward flow is opened inside the embedded block 20. The bottom end position of the Tesla valve channel 21 is also connected to two groups of matching channels 24. The inside of the matching channel 24 is fitted with a piston rod 25. The bottom outer side of the piston rod 25 extends out of the bottom position of the embedded block 20 and is slidably arranged in the interior of the analysis chamber 23. The piston rod 25 is located at the outer position between the analysis chamber 23 and the embedded block 20 and is also connected to a connecting spring 26, and the bottom end of the connecting spring 26 is fixed to the top position of the analysis chamber 23. The inside of the embedded block 20 is fixed inside the container body 1 and is located at the top of the analysis chamber 23. The upper end of the matching channel 24 is tilted downward, and the inner wall of the matching channel 24 and the outer wall of the piston rod 25 are fitted. The end of the piston rod 25 extending into the analysis chamber 23 is also tied with a pull rope 27, and the other end of the pull rope 27 is connected to the float 28. A fixed pulley is also installed inside the bottom end of the analysis chamber 23, and the outer side of the float 28 passes through the outer side of the bottom end of the fixed pulley. The buoyancy of the float 28 is greater than the elastic force of the connecting spring 26. The piston rod 25 forms a sliding structure with the inside of the analysis chamber 23 through the pull rope 27, and the bottom end of the discharge pipe 22 is also connected to a one-way water outlet valve.

[0043] The bottom of the urine collecting hopper 5 is fitted on the top of the feeding hopper 18. When collecting urine from a male patient, the patient's middle urine is collected, and the urine can flow into the feeding hopper 18 through the urine collecting hopper 5. The urine in the feeding hopper 18 flows through the feeding pipe 19, so that the urine flows into the embedded block 20. Since the embedded block 20 is also provided with a Tesla valve channel 21, urine is circulated in one direction through the Tesla valve channel 21, and the discharge pipe 22 is provided for discharge, so that the urine falls onto the test paper in the test paper holder 29. When a float 28 is also placed inside the analysis chamber 23, the float 28 can be made to rise through the setting of the fixed pulley and the pull rope 27 through the continuous increase of urine. The pull rope 27 can drive the piston rod 25 and the pull rope 27 to descend. At this time, a negative pressure will be generated inside the Tesla valve channel 21, so that The Tesla valve channel 21 accelerates the circulation of urine inside the feed hopper 18, so that the urine can fully drip onto the top of the test paper. After the collection is completed, the container body 1 is removed and then the container body 1 is shaken to shake the urine inside the analysis chamber 23. At this time, the feed port 4 is also in a closed state and the gas cannot circulate. In addition, the characteristics of the Tesla valve channel 21 can ensure that urine leakage is avoided. At this time, the test paper can be fully stained with urine and detected by the urine analysis component 3. The above settings can ensure the adequacy of the detection. When cleaning the container body 1 and discharging the urine inside the analysis chamber 23, the bottom of the container body 1 and the analysis chamber 23 are opened by the discharge plug 101, and the urine inside the analysis chamber 23 can be discharged. The purpose of cleaning can be achieved by flushing the container body 1 and the inside of the analysis chamber 23 with water.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
