Description

Technical Field

[0001] This utility model relates to the field of medical consumables quality inspection, and in particular to a quality inspection device for a protein analyzer's testing container. Background Technology

[0002] Hemoglobin (HGB) and C-reactive protein (CRP) are two common blood test indicators with different clinical applications and significance. HGB is a red, iron-containing protein found in red blood cells that carries oxygen. HGB testing can help diagnose anemia and assess oxygen transport in the body. CRP is an acute-phase protein produced by the liver in response to inflammation or tissue damage. CRP testing is typically used to assess the presence of an inflammatory response in the body.

[0003] Currently, for blood analyzers integrating HBG and CRP measurement functions, the quality of the HBG and CRP testing containers (test cells) used directly affects the instrument's testing performance. Initially, determining the quality of the HBG and CRP test cells requires installation in the instrument and testing their relevant performance. If defective products are encountered, disassembly and assembly are difficult, and the debugging time is also long, affecting the instrument's production schedule.

[0004] Currently, the conventional method for inspecting HBG and CRP testing containers involves microscopic observation to examine the smoothness of their optical surfaces. Whether a product is considered good or bad is determined by whether any protrusions or scratches exceed the acceptable threshold. This method is subject to subjective human factors, the judgment criteria are difficult to define, it is time-consuming, and full inspection of materials is challenging.

[0005] Meanwhile, some manufacturers have designed similar testing devices for the instrument's operating environment. HGB and CRP testing cells each require different testing devices. By filling the HGB or CRP testing cell with liquid and testing its background voltage value, the product's quality is determined. This requires a liquid filling device, including syringes, liquid flow pipes, and liquid collection devices, making the entire device quite large. Since the testing cell contains critical materials and typically requires full material inspection, filling it with liquid during the testing process consumes a significant amount of time, causing inconvenience. Furthermore, filling the cell with liquid introduces a degree of contamination. Utility Model Content

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] This utility model provides a quality inspection device for the detection container of a protein analyzer. Please refer to [link / reference]. Figures 1-6 It includes a base 10, a board assembly 20, an HGB detection assembly 30, and a CRP detection assembly 40. The board assembly 20 is mounted on the base 10.

[0043] The HGB detection assembly 30 includes a first bracket 310, a first light source 320, and a first photodetector 330. The first bracket 310 is mounted on the base 10. The first light source 320 and the first photodetector 330 are connected to the first bracket 310, and the optical path of the first light source 320 overlaps with the axis of the first photodetector 330. The first bracket 310 is provided with a first detection position 3110 for placing the HGB detection container. The first detection position 3110 is located between the first light source 320 and the first photodetector 330.

[0044] The CRP detection assembly 40 includes a second bracket 410, a second light source 420, and a second photodetector 430. The second bracket 410 is mounted on the base 10. The second light source 420 and the second photodetector 430 are mounted on the second bracket 410, and the optical path of the second light source 420 is set at an angle to the central axis of the second photodetector 430. The second bracket 410 is provided with a second detection position 4110 for placing the CRP detection container 60.

[0045] The board assembly 20 is electrically connected to the first light source 320, the first photodetector 330, the second light source 420, and the second photodetector 430, respectively.

[0046] According to the protein analyzer detection container quality inspection device in the above embodiments, the first light source 320 is activated, and then the HGB detection container is placed at the first detection position 3110 to obtain a first signal. If the first signal is greater than a preset signal value, the HGB detection container is determined to be a good product. Otherwise, it is a defective product. Similarly, the second light source 420 is activated, and the CRP detection container 60 is placed at the second detection position 4110. The light from the second light source 420 illuminates the CRP detection container 60 and is then scattered to the second photodetector 430, which obtains a second signal. If the second signal is less than a preset value, the CRP detection container 60 is determined to be a good product. Otherwise, it is a defective product. Implementing the protein analyzer detection container quality inspection device of this utility model can achieve the purpose of simple and rapid quality inspection of the detection containers of the protein analyzer.

[0047] It should be noted that HGB testing of containers is based on the optical transmission method, which measures the transmittance of light in the optical region. The signal when the probe light passes through the optical testing area without any obstruction is called the background signal. By comparing the background signal with other measured signals, it is determined whether the HGB testing container is qualified.

[0048] CRP detection requires high sensitivity, and consequently, the surface finish of the optical surface of the detection cell also needs to be high. The scattering method is typically used to inspect the CRP detection cell. The signal (background signal) of the probe light when there is no obstruction in the optical detection area approaches zero or the minimum display value on the digital display.

[0049] Generally speaking, both the first photodetector 330 and the second photodetector 430 convert optical signals into electrical signals. The stronger the optical signal, the stronger the generated electrical signal. The specific form of the electrical signal is either a current signal or a voltage signal.

[0050] Generally speaking, the first light source 320 is an LED light source, and the second light source 420 is a laser light source.

[0051] HGB and CRP testing cells both belong to the field of blood testing, and in many cases, they are tested simultaneously. Therefore, integrating the HGB testing component 30 and the CRP testing component 40 together makes it easy to perform quality inspection of both HGB and CRP testing cells. Furthermore, this solution does not require visual inspection of the HGB and CRP testing cells; based on optical detection principles, it eliminates subjective human factors, has clearly defined judgment criteria, high detection accuracy, short detection time, and strong feasibility. Simultaneously, this device integrates the inspection of two testing cells, occupying less space and bringing convenience to material inspection. Moreover, since no liquid loading is required before testing, it is easy to operate and highly operable for full material inspection.

[0052] The HGB and CRP testing cells do not require connecting pipelines or adding liquid. Based on optical transmission and scattering methods respectively, they achieve short testing time and high accuracy. The operation steps are simple and highly operable for full inspection of critical materials.

[0053] Specifically, the HGB detection component 30 sets a reference value A. If the measured first signal value is greater than A, the HGB detection container is determined to be a good product. Otherwise, it is a defective product.

[0054] The CRP detection component 40 sets a reference value B. If the measured second signal value is less than B, the CRP detection container is determined to be a good product. Otherwise, it is a defective product.

[0055] In some specific embodiments, a cover 50 is also included, which covers the CRP detection component 40.

[0056] To prevent interference from ambient light, the cover 50 is generally preferably black or made of other light-absorbing materials.

[0057] In some specific embodiments, the CRP detection assembly 40 further includes a lens (not shown) disposed between the second photodetector 430 and the second detection position 4110, and the lens typically comprises multiple lenses.

[0058] The lens (not shown) is configured to concentrate the light scattered after the second light source 420 illuminates the CRP detection container 60 onto the second photodetector 430, thereby improving the sensitivity of the second photodetector 430.

[0059] In some specific embodiments, the optical path of the second light source 420 is angled with the central axis of the second photodetector 430 by 10°-30°.

[0060] The second light source 420, the CRP detection container 60, and the second photodetector 430 form a complete scattering loop. After multiple experiments, it was found that setting the angle between the optical path of the second light source 420 and the central axis of the second photodetector 430 to 10°-30° yields the best test results while maintaining the compact structure of the CRP detection assembly 40.

[0061] In some specific embodiments, the board assembly 20 includes a circuit board 210 and a display module 220, with the display module 220 electrically connected to the circuit board 210.

[0062] Circuit board 210 is responsible for supplying power to the first light source 320 and the second light source 420, and for reading and analyzing the signals from the first photodetector 330 and the second photodetector 430. Display module 220 is used to display the first and second signals so that testers can determine whether the product under test is qualified.

[0063] The display module 220 can be a single display screen or multiple display screens. In the case of only one display screen, both the first signal and the second signal are displayed on the same screen.

[0064] Preferably, the display module 220 includes two displays. One display is configured to correspond to the HGB detection component 30, and the other display is configured to correspond to the CRP detection component 40.

[0065] In addition, it should be noted that the information transmission between the HGB detection component 30 and the CRP detection component 40 and the board component 20 can also be wireless, such as Bluetooth transmission or mobile signal transmission, etc.

[0066] In some specific embodiments, the board assembly 20 further includes a housing 230 that covers the circuit board 210 to shield the circuit board 210 from interference.

[0067] The main function of the housing 230 is to provide shielding. It is usually made of metal and is mainly used to prevent the circuit board 210 from being interfered with.

[0068] In some specific embodiments, the board assembly 20 also includes a buzzer (not shown) electrically connected to the circuit board 210.

[0069] A buzzer is an electronic sounder widely used in various electronic products to emit sound signals. If circuit board 210 detects that the HGB test container and / or CRP test container 60 are defective, it will control the buzzer to sound. Quality inspectors will know that there are defective products among the HGB test containers and / or CRP test containers 60 to be tested upon hearing the sound.

[0070] It should be noted that in this embodiment, the buzzer can not only emit an alarm sound, but also provide voice announcements. For example, it can announce "qualified" and "unqualified." Or, for example, it can announce the specific values ​​of the first and second signals.

[0071] In some specific embodiments, the board assembly 20 further includes a power supply 250, which is electrically connected to the circuit board 210.

[0072] The function of power supply 250 is to convert high-voltage AC power into low-voltage DC power, thereby providing power to circuit board 210.

[0073] In some specific embodiments, the housing 230 covers the power supply 250 and the housing 230 has heat dissipation holes 2310 at the power supply 250.

[0074] The power supply 250 generates a lot of heat, and the heat dissipation holes 2310 on the housing 230 can enhance the heat dissipation of the power supply 250.

[0075] In some specific embodiments, the base 10 has a handle 110 to facilitate moving the base 10.

[0076] The handle 110 allows quality control personnel to easily move the entire protein analyzer's testing container quality control device. Typically, the handles 110 are located on both sides of the base 10. The base 10 usually also has four feet for easy placement.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
