Description

Technical Field

[0001] This utility model relates to the field of urine analyzer technology, specifically to a testing mechanism for a urine analyzer. Background Technology

[0002] When analyzing urine using multiple urine analysis test strips (dry chemistry method), it is necessary to analyze the color of each test strip individually to detect the content of each component in the urine. The applicant disclosed a test strip delivery mechanism based on a semi-automatic urine analyzer in patent application number CN202210928197.X. This delivery mechanism is equipped with a scanning unit consisting of a hybrid stepper motor, stepper wheels, a stepper belt, and pulleys. When the test strip is pushed to the scanning unit position by the test strip scraper, the hybrid stepper motor drives the stepper wheels to rotate. The stepper wheels drive the stepper belt to move forward or backward, and the stepper belt drives the scanning sensor to reciprocate on the guide rod to complete the scanning of each test strip on the test strip. However, the applicant found that the scanning unit assembly structure in the above technology is complex, which is not conducive to the miniaturization design of the urine analyzer, and the transmission coordination between the motor, wheels, and belt is also prone to problems, affecting the normal movement of the scanning sensor. Therefore, this application proposes a testing mechanism for a urine analyzer. Utility Model Content

[0003] To address the aforementioned issues, this application provides a testing mechanism for a urine analyzer.

[0004] The objective of this utility model is achieved through the following technical solution: a detection mechanism for a urine analyzer, comprising a housing and a circuit board disposed within the housing; a detection component is disposed on the circuit board, and a slot located below the detection component is disposed within the housing, the slot being used to insert a test strip holder;

[0005] The detection component includes a plurality of light sources arranged at intervals along the length of the slot, and color sensors respectively disposed between two adjacent light sources.

[0006] The circuit board is electrically connected to a display screen, and the outer casing has a window corresponding to the display screen.

[0007] The circuit board is electrically connected to buttons and a power source.

[0008] The housing has two slot plates arranged in parallel inside, forming a slot between the two slot plates.

[0009] The housing contains support pillars for supporting the circuit board.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0021] Example

[0022] like Figure 1-5 As shown, this embodiment discloses a detection mechanism for a urine analyzer, which includes a housing 1 and a circuit board 6 installed inside the housing 1. The housing 1 consists of an upper shell and a lower shell, which are detachably fastened together. Specifically, a slot can be provided around the lower shell, and the lower end of the upper shell can be fastened into the slot, thereby fastening the upper and lower shells together. A support post 11 is provided inside the lower shell, and the circuit board 6 can be mounted on the support post 11 with screws.

[0023] In addition, such as Figure 3 As shown, the circuit board 6 is equipped with a detection component, a button 4, a power supply 10, and a display screen 5, all electrically connected to it. The housing 1 has a viewing 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 wall of the housing 1 for easy operation and control. The power supply 10 can be powered by a button battery.

[0024] The detection component includes several light sources 7 spaced apart, and color sensors 8 respectively disposed between two adjacent light sources 7, i.e., one color sensor 8 is disposed between every two adjacent light sources 7. Correspondingly, two slot plates 14 are arranged parallel inside the lower shell, forming a slot 9 between the two slot plates 14. The slot 9 is located below the detection component and is used to insert a test strip holder loaded with test strips. The outer shell 1 is provided with an insertion port 2 communicating with the slot 9, through which the test strip holder can be inserted into the slot 9. Specifically, the slot plates 14 are "L"-shaped plates, with the vertical part of the "L"-shaped plates connected to the lower shell, and the horizontal parts of the two "L"-shaped plates facing each other. Thus, the vertical parts of the two "L"-shaped plates enclose the aforementioned slot 9, while the horizontal parts can limit the test strip holder in the vertical direction, such as... Figure 4 As shown. In addition, a baffle is provided at the end of the slot 9 to limit the depth of the test strip holder inserted into the housing 1.

[0025] In the specific setup, the light sources 7 are arranged sequentially at intervals along the length of the slot 9. When the test strip holder containing the test strips is inserted into the slot 9, the test strip pieces on the test strip are also distributed along the length of the slot 9. The intervals between the light sources 7 correspond to the test strip pieces on the test strip. In other words, when the test strip holder containing the test strips is inserted into the slot 9, each test strip piece is located below a light source 7, and a color sensor 8 receives the light signals reflected from two adjacent test strip pieces.

[0026] During testing, each light source 7 is lit up one by one from the outside to the inside or from the inside to the outside, illuminating the test strip below it. During this process, the color sensor 8 sequentially receives the light signals reflected by two adjacent test strips, and transmits the light signals to the circuit board 6. The circuit board 6 analyzes the content of the urine component detected by the test strip.

[0027] like Figure 3 , 5 As shown, in another implementation, the lower shell is provided with a buckle plate 12 located in the slot 9. The surface of the buckle plate 12 is provided with an upwardly protruding latch 13, and the latch 13 is provided with a guide slope. Correspondingly, the bottom of the test strip holder is provided with a latch that matches the latch 13. When the test strip holder is inserted into the slot 9, the front end of the test strip holder first abuts against the guide slope on the latch 13, causing the buckle plate 12 to deform downward. As the test strip holder continues to be inserted into the slot 9, when the latch 13 is aligned with the latch, the buckle plate 12 returns to its original position, and the latch 13 snaps into the latch, fixing the test strip holder in the slot 9. At this time, it is exactly in the state described above where a test strip is facing a light source 7. When it is necessary to remove the test strip holder, the buckle plate 12 is bent downward to disengage the latch 13 from the latch, and the test strip holder can then be pulled out.

[0028] This embodiment has a simple structure, which does not require a complex mechanical transmission scanning mechanism and is easy to maintain.

[0029] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
