[0037] The utility model relates to a urine testing instrument 100, which includes a housing 1, a pump 2, a sampling device 3, a detection device 4, a control device, a valve 6 and a driving mechanism. The housing 1 has space for the pump 2, the sampling device 3, the detection device 4, the control device, the valve 6 and the driving mechanism, and is used to carry the pump 2, the sampling device 3, the detection device 4, the control device, the valve 6 and the driving mechanism. The sampling device 3 is used to collect samples, such as urine. The inlet of the sampling device 3 is located at the top shell 12 of the housing 1, which is convenient for receiving urine, and the outlet is connected to the inlet of the pump 2, and the sample can be transported to the detection device 4 through the pump 2 for detection. The detection device 4 includes a reagent kit and a detection module. The test kit includes a mounting plate 41 and a plurality of reagent capsules 42, wherein the plurality of reagent capsules 42 are respectively used to contain different reagents, such as various suitable reagents for urine detection, including but not limited to reagents used for routine detection, such as urine pH, urine white blood cells (WBC / LEU), urine nitrite (NIT), urine protein (PRO), glucose (GLU), urobilinogen (URO / UBG), ketone bodies (KET), occult blood (BLU), bilirubin (BIL), ascorbic acid (VC), salts, creatinine (CrE), reagents for tumor markers, such as alpha-fetoprotein, carcinoembryonic antigen, albumin, urine β2-microglobulin, etc., and reagents for detecting microorganisms, such as nicotine, ethanol, vitamin C, etc.

[0038] The mounting plate 41 has an annular body and a plurality of drainage holes 411 penetrating the side of the annular body. The plurality of drainage holes 411 are spaced apart and distributed circumferentially along the annular body. The reagent outlet 422 of the reagent capsule 42 can be closedly connected to the corresponding drainage holes 411 .

[0039] The detection module includes a flow channel plate 43, a light source device and a photosensitive sensor. The flow channel plate 43 is located below the mounting plate 41 and the valve 6, and is used to receive urine and reagents flowing out of the reagent capsule 42. The top of the flow channel plate 43 has an annular flow channel formed by being recessed downward relative to the top surface and at least one test pit, the test pit is connected to the annular flow channel, and the annular flow channel can receive the reagent flowing out of the reagent flow outlet 422.

[0040] The light source device and the photosensitive sensor are respectively arranged on the flow channel plate 43, and are used for detecting samples, such as urine, to obtain human body related parameters. The light source device can be LED light, and the photosensitive sensor and LED light are connected to external equipment and control devices. After urine and reagents flow through the flow channel plate 43, the control device controls the LED and photosensitive sensor to start. After the detection is completed, the control device controls the LED and photosensitive sensor to turn off and transmit the data to the external equipment. The operating principle of the urine tester 100 of the utility model is the same as that of patent CN218445524U. The detailed principle can refer to patent CN218445524U.

[0041] The valve 6 is used to drive the reagent and urine to flow into the flow channel plate 43. Specifically, the valve 6 includes an annular valve body 61 and a plurality of valve cores 62, the valve body 61 has a plurality of main channels and a plurality of outflow ports, the plurality of main channels and the plurality of outflow ports are respectively arranged at intervals along the circumference of the valve body 61, the plurality of outflow ports are respectively connected to the inner walls of the plurality of main channels, each valve core 62 cooperates with a corresponding main channel to operably open or close each outflow port, and the inlet of each main channel is connected to the corresponding drainage hole 411. The operating principle of the valve 6 can also refer to patent CN218445524U.

[0042] The driving mechanism is used to drive the corresponding valve core 62 to open or close the valve 6. The control device is electrically connected to the pump 2, the driving mechanism and the detection device 4, and is configured to control the operation of the pump 2, the driving mechanism and the detection device 4. The pump is connected to the sampling device and the main flow channel of the valve body, and can operably drive the sample to be tested and the reagent to enter the flow channel plate. The operation mode of the driving mechanism and the control device can also refer to patent CN218445524U.

[0043] The shape of the reagent capsule 42 of the present utility model is different from that of the reagent capsule 42 in the patent CN218445524U. Specifically, the reagent capsule 42 also has a containing space 421 for containing the reagent and a reagent outflow port 422 and is elastic, but the curvature of the inner wall 423 of the containing space 421 of the reagent capsule 42 is smaller than the curvature of the outer surface 424 of the reagent capsule 42. That is, the curvature of the inner wall 423 of the reagent capsule 42 is smaller than the curvature of the outer surface 424. When it is necessary to extract the reagent from the reagent capsule 42, the reagent capsule 42 is evacuated and thus concave inwardly. Since the curvature of the inner wall 423 of the reagent capsule 42 is small, it is easier to squeeze the reagent, especially when there is little reagent in the reagent capsule 42, it is easier to squeeze the reagent out of the reagent outflow port 422.

[0044] In the embodiment shown in the figure, the outer surface 424 of the reagent capsule 42 is shaped as a cylinder extending along an axis, and the opening of the containing space 421 is located at one end of the reagent capsule 42 along the axis, and the end of the body away from the opening is an arc surface convex outward. The vertical distance from the inner wall 423 of the containing space 421 to the axis gradually increases from both ends to the middle, and the inner wall 423 of the containing space 421 is an arc surface, which is in the shape of a bowling ball as a whole. When the opening of the containing space 421 is evacuated, the reagent capsule 42 as a whole can be sunken inward, and then the inner wall 423 of the containing space 421 moves toward the axis. Since the arc of the containing space 421 is small, that is, the curvature of the bend is small, the inner wall 423 of the containing space 421 can be more easily fitted to each other relative to the outer surface 424, and then the reagent can be more easily squeezed from the reagent outlet 422 to the outside, reducing the waste of the reagent and prolonging the service life of the reagent kit.

[0045] Furthermore, the inner wall 423 of the containing space 421 of the reagent capsule 42 is a relatively smooth curved surface and is symmetrical with respect to the axis. It should be understood that in other embodiments, the inner wall 423 of the reagent capsule 42 may also be an inclined surface, and the end of the outer surface away from the opening may also be a plane.

[0046] The detection device 4 also includes a plurality of drainage tubes, which are respectively connected to the annular body and respectively provided with drainage holes 411. The plurality of drainage tubes and the mounting plate 41 are integrally formed and respectively protrude radially outward from the mounting plate 41. One ends of the plurality of drainage tubes are respectively inserted into the reagent outlets 422 of the plurality of reagent capsules 42, and the other ends are located in the annular body and connected to the main flow channel.

[0047] The housing 1 includes a bottom housing 11 and a bottom housing 11, wherein the bottom housing 11 is used to be installed on the inner wall of the toilet, and the pump 2, the detection module, the flow channel plate 43 and the valve 6 are respectively installed on the bottom housing 11.

Specifically, the top housing 12 includes a first housing 121 and a second housing 122, wherein the first housing 121 covers the sampling device 3, the pump 2, the detection module, the flow channel plate 43 and the valve 6 and is detachably connected to the bottom housing 11.

[0048] In the embodiment shown in the figure, the first housing 121 includes an outer shell 1211 and an inner shell 1212. The outer shell 1211 covers the sampling device 3 and the pump 2 and is detachably connected to the bottom shell 11. In addition, one end of the outer shell 1211 facing the second housing 122 is connected to the inner wall of the bottom shell 11 through a vertical side plate 1215, so that the outer shell 1211 can completely cover the sampling device 3, the pump 2 and other components.

[0049] The end of the housing 1211 facing the second housing 122 is provided with a recessed area 1213, and the recessed area 1213 is located at the bottom of the second housing 122. After the second housing 122 and the first housing 121 are respectively connected to the bottom housing 11, the second housing 122 covers the recessed area 1213 and the top surface of the second housing 122 is flush with the first housing 121, so that the top surface of the second housing 122 does not protrude from the first housing 121. In addition, the recessed area 1213 faces one end of the second housing 122 and is provided with an inwardly recessed snap-in groove 1214, and the bottom of the second housing 122 is provided with a protruding snap-in block or snap-in column, which can be snapped into the snap-in groove 1214 when the second housing 122 is installed on the bottom housing 11, so that the second housing 122 and the first housing 121 are snap-in. Of course, in other embodiments, other detachable connection methods, such as screws, etc., can also be used.

[0050] The inner shell 1212 is located on the bottom surface of the second shell 122 and covers the detection module, the flow channel plate 43 and the valve 6. The inner shell 1212 is connected to the end of the outer shell 1211 facing the second shell 122, and the inner shell 1212 and the outer shell 1211 are integrally formed, that is, the inner shell 1212 is equivalent to the outer shell 1211 extending toward the direction of the second shell 122 and is connected to the end of the outer shell 1211 facing the second shell 122.

[0051] In the embodiment shown in the figure, the cross section of the inner shell 1212 along the horizontal direction is roughly semicircular and connected to the center of the outer shell 1211. The two snap-in grooves 1214 are respectively located on both sides of the inner shell 1212 and are spaced from the inner shell 1212. The bottom surface of the inner shell 1212 is connected to the top surface of the arc-shaped valve body 61 through another arc-shaped side plate 1216, and the arc-shaped side plate 1216 and the side plate of the outer shell 1211 are integrally formed and extend in the vertical direction, that is, the arc-shaped side plate 1216 is located on the bottom surface of the inner shell 1212 and the top end is connected to the inner shell 1212, and the bottom end is connected to the top surface of the valve body 61. The first shell 121 can wrap the sampling device 3, the pump 2, the detection module, the flow channel plate 43 and the valve 6 between the first shell 121 and the bottom shell 11. That is, the entire first shell 121 is integrally formed and is sealed with the bottom shell 11 or the top surface of the valve body 61 by means of sealant or other sealing rings, thereby preventing external liquid from entering between the first shell 121 and the bottom shell 11 .

[0052] The inner shell 1212 is also detachably connected to the second shell 122. Specifically, the top surface of the inner shell 1212 is provided with a mounting groove 1221, and the mounting groove 1221 is provided with a magnet 1217, and the bottom surface of the second shell 122 is also provided with a mounting groove 1221 for installing a magnetic sheet attracted to the magnet 1217, and the sealing of the inner shell 1212 and the second shell 122 can be strengthened by magnetic attraction. Of course, in other embodiments, the inner shell 1212 can also be snapped with the second shell 122, for example, a protruding column is provided on the top surface of the inner shell 1212, and a groove is provided on the bottom surface of the second shell 122. When the second shell 122 is installed, the column can be snapped into the groove, thereby strengthening the sealing of the connection between the first shell 121 and the second shell 122.

[0053] The second shell 122 is detachably connected to the bottom shell 11. The reagent kit is detachably connected to the second shell 122. Specifically, the bottom wall of the second shell 122 is provided with a slot 1223 matching the shape of the top of the mounting plate 41, so that the top of the mounting plate 41 is located in the slot 1223. After the second shell 122 is disassembled, the mounting plate 41 and the plurality of reagent capsules 42 can be disassembled together with the second shell 122, so that new reagent capsules 42 can be replaced.

[0054] The urine test instrument 100 also includes a support plate 5 and a receiving plate 7, wherein the support plate 5 is connected to the flow channel plate 43 and is fixedly connected or clamped to the bottom shell 11.

[0055] In addition, the top surface of the receiving plate 7 is provided with a plurality of abutting columns 71, and the bottom surface of the second shell 122 is also provided with a plurality of receiving columns 1222. The plurality of abutting columns 71 and the plurality of receiving columns 1222 abut against each other, which can increase the stability of the receiving plate 7. The plurality of reagent capsules 42 are located between the receiving plate 7 and the second shell 122, and the receiving plate 7 can also cover the plurality of reagent capsules 42, which increases the stability of the plurality of reagent capsules 42.

[0056] It should be understood that in other embodiments, the plurality of abutment posts 71 may also directly abut against the second shell 122 , that is, the receiving posts 1222 are not provided.

[0057] The housing 1 of the present invention only has a top shell 12 and a bottom shell 11 , and no protective shell is provided, but can still meet the sealing requirements, which is not only convenient for assembly, but also can reduce the volume of the urine testing instrument 100 to a certain extent by reducing the protective shell.
