DETAILED DESCRIPTION

[0033] In order to enable people in this technical field to better understand the solution of this application, the technical solution in the embodiment of this application will be clearly and completely described below in combination with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all of the embodiments.

[0034] Example

[0035] like Figure 1-3 As shown, this embodiment discloses a urine analyzer, which includes an analysis host 23 and a test strip holder 24. The test strip holder 24 is detachably inserted into the analysis host 23; wherein, the test strip holder 24 is used to load the test strip 18 to be tested, and the analysis host 23 is used to test the test strip 18 loaded on the test strip holder 24.

[0036] like Figure 4 As shown, the test strip holder 24 includes a test strip placement portion 22 and a urine collection portion 17 that are interconnected. The test strip placement portion 22 and the urine collection portion 17 can be integrally formed. Furthermore, both the test strip placement portion 22 and the urine collection portion 17 have cavities within them, and the cavities within the test strip placement portion 22 and the urine collection portion 17 are interconnected. When installed, the test strip placement portion 22 is removably inserted into the analysis host 23.

[0037] like Figure 4 As shown, the upper surface of the urine collection portion 17 is provided with a plurality of urine collection holes 16 communicating with the internal cavity thereof. The urine collection holes 16 can be arranged in an array, such as a rectangular array, a circular array, or another polygonal array. During use, the urine is collected by the urine collection portion 17, which then enters the internal cavity of the urine collection portion 17 through the urine collection holes 16 and then flows from the internal cavity of the urine collection portion 17 to the internal cavity of the test strip placement portion 22.

[0038] In order to make the urine flow better from the internal cavity of the urine collection part 17 to the internal cavity of the test strip placement part 22, as shown in FIG. Figure 7 As shown, the internal cavity of the urine collection part 17 is tilted upward from one end close to the test strip placement part 22 to the other end. In the specific setting, only the internal cavity of the urine collection part 17 can be tilted, while the outer surface of the urine collection part 17 is still flat like the test strip placement part 22. Alternatively, the urine collection part 17 and its internal cavity can be tilted as a whole, as shown in FIG. Figure 7 Specifically, the urine collection portion 17 can be tilted upward by 10-30 degrees, and in this embodiment, it is set at 15 degrees. By tilting the urine collection portion 17, it helps urine flow from the urine collection portion 17 to the test strip placement portion 22 and contact the test strip 18 on the test strip placement portion 22. Therefore, during use, only a small amount of urine needs to be collected, avoiding the collection of large amounts of urine that may cause urine overflow and contamination of the environment.

[0039] In the specific setting, an outward-protruding shoulder can be set on the circumference of the outer surface of the urine collection part 17. The shoulder is located at the rear end of the urine collection hole 16. The shoulder can block urine from flowing from the outer surface of the urine collection part 17 to the test strip placement part 22. Only urine entering from the urine collection hole 16 will flow to the test strip placement part 22.

[0040] In addition, if Figure 4 、 5 As shown, the upper surface of the test strip placement portion 22 is provided with a test strip placement groove 15 that is recessed into the interior thereof. The test strip placement groove 15 extends along the length direction of the test strip placement portion 22 and is used to place a test strip 18. A urine flow channel 19 is formed between the long side groove wall of the test strip placement groove 15 and the side wall of the test strip placement portion 22. Specifically, the urine flow channel 19 may be formed between one long side groove wall of the test strip placement groove 15 and the side wall of the test strip placement portion 22, or the urine flow channel 19 may be formed between two opposite long side groove walls of the test strip placement groove 15 and the side wall of the test strip placement portion 22. In other words, there is a urine flow channel 19 on each of the opposite sides of the test strip placement groove 15, as shown in FIG. Figure 6 In this way, the urine flowing from the internal cavity of the urine collection part 17 into the test strip placement part 22 is divided into two urine flow channels 19.

[0041] like Figure 6 、 7 As shown, at least one liquid hole 20 is provided on the two opposite long side groove walls of the test strip placement groove 15, so that the test strip placement groove 15 is connected to the urine flow channel 19 through the liquid hole 20, that is, urine in the urine flow channel 19 can enter the test strip placement groove 15 through the liquid hole 20, thereby contacting the test strip 18 placed in the test strip placement groove 15.

[0042] In the specific setting, the number of the liquid holes 20 is the same as the number of test strips on the test strip 18, and the positions of the liquid holes 20 correspond one-to-one to the test strips on the test strip 18 placed in the test strip placement slot 15. That is, one side of each test strip absorbs urine flowing through the urine flow channel 19 from a separate liquid hole 20, and they do not affect each other, further reducing the probability of urine contamination.

[0043] In addition, the end of the test strip placement slot 15 away from the urine collection portion 17 is provided with an extra urine storage chamber 21 connected to the urine flow channel 19. Figure 7 、 8 shown.

[0044] The urine collected from the urine collection hole 16 flows forward along the urine flow channel 19. When the urine passes through the liquid hole 20, a small amount of urine enters the test strip placement groove 15 from the liquid hole 20 and contacts the corresponding test paper piece on the test strip 18. Since the test paper piece has adsorption properties, once the urine contacts the test paper piece, the test paper piece continuously adsorbs the urine flowing along the urine flow channel 19 until the test paper piece is saturated. When the test paper piece is saturated, if there is excess urine, due to the lack of the adsorption effect of the test paper piece, the excess urine in the urine flow channel 19 is not easy to enter the test strip placement groove 15 from the liquid hole 20, but continues to flow forward to be stored in the excess urine storage chamber 21, thus completing the urine collection.

[0045] like Figure 9-13 As shown, the analysis host 23 includes a housing 1 and a circuit board 6 disposed within the housing 1. The housing 1 comprises an upper shell and a lower shell, which are detachably fastened together. Specifically, a slot can be provided around the circumference of the lower shell, into which the lower end of the upper shell snaps, thereby fastening the upper and lower shells together. Support columns 11 are provided within the lower shell, and the circuit board 6 can be mounted on the support columns 11 using screws.

[0046] In addition, if Figure 11 As shown, the circuit board 6 is provided with a detection component electrically connected thereto, a button 4, a power supply 10, and a display screen 5. The housing 1 is provided with a window 3 corresponding to the display screen 5, through which the detection results displayed on the display screen 5 can be viewed. The button 4 extends to the shell wall of the housing 1 for easy operation. The power supply 10 can be implemented using a button battery.

[0047] The detection assembly includes a plurality of light sources 7 arranged at intervals and color sensors 8 disposed between two adjacent light sources 7, that is, a color sensor 8 is disposed between each two adjacent light sources 7. The number of light sources 7 is the same as the number of test strips on the test strip 18. Accordingly, two slot plates 14 are disposed in parallel within the lower housing, forming a slot 9 between the two slot plates 14. The slot 9 is located below the detection assembly and is used to insert a test strip holder 24 loaded with a test strip. The housing 1 is provided with an insertion port 2 that communicates with the slot 9. The test strip holder 24 can be inserted into the slot 9 through the insertion port 2. That is, during use, the test strip placement portion 22 of the test strip holder 24 can be inserted into the slot 9 through the insertion port 2. In the specific setting, the slot plate 14 is an "L"-shaped plate, the vertical part of the "L"-shaped plate is connected to the lower shell, and the horizontal parts of the two "L"-shaped plates are arranged facing each other. In this way, the vertical parts of the two "L"-shaped plates surround the above-mentioned slot 9, and the horizontal parts can define the test strip placement portion 22 in the vertical direction, such as Figure 13 In addition, a baffle can be provided at the end of the slot 9 to limit the depth of the test strip placement portion 22 inserted into the housing 1 .

[0048] In a specific configuration, the light sources 7 are spaced apart along the length of the slot 9. When the test strip placement portion 22 loaded with the test strip 18 is inserted into the slot 9, the test strips on the test strip 18 are also spaced apart along the length of the slot 9. The spacing between the light sources 7 corresponds to the test strips on the test strip 18. In other words, when the test strip placement portion 22 loaded with the test strip 18 is inserted into the slot 9, each test strip on the test strip 18 is located below a light source 7, and a color sensor 8 can receive light signals reflected by two adjacent test strips.

[0049] With the above structure, during testing, the test strip 18 is first placed on the test strip placement portion 22, urine is then collected through the urine collection portion 17, and the test strip holder 24 is then plugged into the analysis host 23. Pressing the button 4 causes the analysis host 23 to begin testing. During testing, the circuit board can illuminate each light source 7 one by one, either from the outside in or from the inside out, illuminating the test strips beneath them. During this process, the color sensor 8 sequentially receives the light signals reflected by two adjacent test strips. The color sensor 8 transmits the light signals to the circuit board 6, which analyzes the urine component content corresponding to each test strip and displays the test results on the display screen 5.

[0050] like Figure 11 、 13 As shown, as another implementation, the lower housing is provided with a gusset plate 12 positioned within the slot 9. The surface of the gusset plate 12 is provided with an upwardly protruding buckle 13, and the buckle 13 is provided with a guiding inclined surface. Accordingly, a latch is provided at the bottom of the test strip placement portion 22 to match the latch 13. When the test strip placement portion 22 is inserted into the slot 9, the front end of the test strip placement portion 22 first abuts against the guiding inclined surface of the latch 13, causing the gusset plate 12 to deform downward. As the test strip placement portion 22 continues to be inserted into the slot 9, when the latch 13 faces the latch, the gusset plate 12 returns to its original position, and the latch 13 snaps into the latch. The test strip holder 24 is then fixed in the slot 9, at which point it is in the aforementioned state where a test strip is facing a light source 7. To remove the test strip holder 24, the gusset plate 12 is bent downward to disengage the latch 13 from the latch, at which point the test strip holder 24 can be withdrawn.

[0051] This embodiment has a simple structure and, compared to the traditional method of placing a test strip directly into a urine cup, can prevent urine contamination and improve the accuracy of detecting various indicators in urine. In addition, by providing multiple light sources 7 and color sensors 8, each light source 7 corresponds to a test strip on the test strip, and the color sensor 8 collects the light signals reflected by two adjacent test strips to achieve urine analysis, the structure is simpler, eliminating the need for a complex mechanical transmission scanning mechanism to scan the test strips, and facilitating maintenance.

[0052] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
