Description

Technical Field

[0001] This utility model relates to the field of test strip signal reading, specifically to a colloidal gold test strip signal reading device. Background Technology

[0002] Colloidal gold test strips are widely used in clinical diagnosis, food safety, and environmental monitoring due to their ease of use and rapid detection.

[0003] Currently, the interpretation of test results for colloidal gold test strips is mostly done manually by visual inspection. Manual interpretation relies on the experience of the testers and is easily affected by subjective factors. It has low accuracy in identifying weak positive bands and cannot achieve quantitative analysis. Moreover, manual results rely on manual recording, which makes it difficult to trace and fails to meet the requirements of modern testing for accuracy and objectivity.

[0004] To address this, a colloidal gold test strip signal reading device is proposed. Utility Model Content

[0005] In view of the problems with signal reading of existing colloidal gold test strips, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide a colloidal gold test strip signal reading device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A colloidal gold test strip signal reading device includes a housing, a signal reading component fixedly mounted on the inner wall of the top of the housing, and a display fixedly mounted on the top of the housing; The box has a reading opening on one side and test strip positioning mechanisms on both sides of the inner sidewall of the box. The test strip positioning mechanism includes two telescopic rods symmetrically fixed on the inner sidewall of the box. One end of the two telescopic rods is fixed with the same positioning clamp, and the rod walls of the two telescopic rods are sleeved with springs. The test strip ejection mechanism is provided on the side of the box away from the reading opening.

[0008] Preferably, the side wall of the positioning clamp is provided with an L-shaped clamping groove, one end of the positioning clamp extends into the interior of the reading opening, and one end of the positioning clamp is provided with an arc-shaped guide groove.

[0009] Preferably, a positioning piece is fixedly provided on the top of the side wall of the L-shaped clamping groove.

[0010] Preferably, the test strip ejection mechanism includes a push rod slidably disposed on the side wall of the box, one end of the push rod extending between the two positioning clamps, and both ends of the push rod are fixedly provided with anti-drop blocks.

[0011] Preferably, test strip collection boxes are fixedly provided on both sides of the box.

[0012] Furthermore, a ring-shaped supplementary light is fixedly provided on the top inner wall of the housing and on the periphery of the signal reading component.

[0013] Preferably, a handle is fixedly provided on the top of the box.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, through the inclusion of a signal reading component, a display, and a ring-shaped supplementary light, provides a uniform, shadow-free lighting environment, eliminating interference from surface reflections or uneven lighting on the test strip, creating stable optical conditions for the signal reading component, and ensuring the clarity of signal acquisition. The signal reading component converts the colloidal gold colorimetric signal into a digital result and presents it intuitively on the display, replacing manual visual interpretation. This avoids the possibility of weak positive missed detections and false positives caused by differences in human experience and visual fatigue, and also enables quantitative or semi-quantitative analysis of the test results, meeting the requirements of modern testing for objectivity and accuracy.

[0015] 2. This utility model, through a test strip positioning mechanism composed of a telescopic rod, a spring, and a positioning clamp, can automatically adapt to colloidal gold test strips of different widths. When the test strip is inserted, the spring's rebound force pushes the positioning clamp to tightly hold both sides of the test strip. The L-shaped clamping groove achieves upper and lower limit positioning, the positioning piece further assists in fixing, and the arc-shaped guide groove guides the test strip to be inserted smoothly, effectively avoiding test strip deviation and skew, and improving the accuracy of the test results.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figure 1-5 The colloidal gold test strip signal reading device shown includes a housing 1. A signal reading component 2, which is a photoelectric sensor, is fixedly installed on the inner wall of the top of the housing 1. A ring-shaped supplementary light 8 is fixedly installed on the inner wall of the top of the housing 1, surrounding the signal reading component 2. The ring-shaped supplementary light 8 can illuminate the interior of the housing 1, improving the accuracy of detection. A display 3 is fixedly installed on the top of the housing 1. A controller (not shown) is installed inside the housing 1 and is electrically connected to the signal reading component 2, the display 3, and the ring-shaped supplementary light 8. The signal reading component 2 collects signals from the detection line (T line) and the control line (C line) of the test strip, converts the colloidal gold color development signal into an electrical signal, and then transmits it to the controller. The instrument analyzes the data and displays the qualitative or semi-quantitative test results on the display 3 on the top of the box 1. A reading opening 4 is provided on one side of the box 1, and test strip positioning mechanisms 5 are provided on both sides of the inner sidewall of the box 1. The test strip positioning mechanism 5 includes two telescopic rods 51 symmetrically fixed on the inner sidewall of the box 1. One end of the two telescopic rods 51 is fixed with the same positioning clamp 52. Springs 53 are sleeved on the rod walls of the two telescopic rods 51. An L-shaped clamping groove 54 is opened on the sidewall of the positioning clamp 52. One end of the positioning clamp 52 extends into the interior of the reading opening 4, and an arc-shaped guide groove 55 is provided on one end of the positioning clamp 52. A positioning piece 56 is fixed on the top of the sidewall of the L-shaped clamping groove 54.

[0021] A test strip ejection mechanism 6 is provided on the side of the housing 1 away from the reading opening 4. The test strip ejection mechanism 6 includes a push rod 61 slidably disposed on the side wall of the housing 1. One end of the push rod 61 extends between two positioning clamps 52, and both ends of the push rod 61 are fixedly provided with anti-drop blocks 62. The anti-drop blocks 62 can prevent the push rod from sliding off the side wall of the housing 1 during the pushing process, ensuring stable operation. The push rod 61 is pushed by hand, so that one end of the push rod 61 pushes the colloidal gold test strip towards the reading opening 4 until the test strip part extends out of the reading opening 4. At this time, the test strip can be manually removed.

[0022] Both sides of the box 1 are fixed with test strip collection boxes 7, which can temporarily collect the test strips after testing and avoid pollution or chaos caused by random disposal; the top of the box 1 is fixed with a handle 9, which can be used to carry the equipment in different scenarios such as on-site testing and primary medical points, improving portability.

[0023] Working principle: During use, the reacted colloidal gold test strip is inserted into the reading opening 4 of the housing 1. The colloidal gold test strip contacts the arc-shaped guide groove 55 at one end of the positioning clamp 52. Guided by the arc-shaped guide groove 55, it smoothly enters between the two positioning clamps 52. During the insertion process, the two sides of the colloidal gold test strip push the positioning clamps 52 to move to both sides. The positioning clamps 52 drive the telescopic rod 51 to retract. At the same time, the spring 53 on the wall of the telescopic rod 51 is compressed. The rebound force of the spring 53 makes the positioning clamps 52 fit tightly against both sides of the test strip. With the assistance of the L-shaped clamping groove 54 and the positioning piece 56, it ensures that the colloidal gold test strip remains centered and stable during the detection process, avoiding the impact of positional deviation on signal reading accuracy. It is compatible with colloidal gold test strips of different widths. After the test strip is positioned, the ring-shaped supplementary light 8 on the inner wall of the top of the chamber 1 is activated. The ring-shaped supplementary light design provides uniform illumination, eliminating interference from reflections or shadows on the test strip surface, and creating a stable optical environment for the signal reading component 2. The signal reading component 2 (photoelectric sensor) collects signals from the test line T and control line C of the test strip, converts the colloidal gold colorimetric signal into an electrical signal, and then transmits it to the controller for analysis. Finally, the qualitative or semi-quantitative data of the test results is displayed on the display 3 on the top of the chamber 1, realizing the digital presentation of the results and avoiding subjective errors from manual interpretation. After the test is completed, push the push rod 61 away from the reading opening 4 on the side of the box 1. One end of the push rod 61 extends between the two positioning plates 52, pushing the colloidal gold test strip towards the reading opening 4 until the test strip extends out of the reading opening 4. At this time, the test strip can be manually removed, or the removed test strip can be directly placed into the test strip collection box 7 on both sides of the box 1 to achieve temporary centralized storage of the test strips after the test, avoiding pollution or chaos caused by random disposal.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
