Description

Technical Field

[0001] This utility model relates to the field of biological optical detection instrument technology, and in particular to a multifunctional portable single-channel detection device. Background Technology

[0002] Rapid immunochromatographic detection technologies (such as colloidal gold assay and fluorescence immunochromatography) are based on chromatography and antigen-antibody specific immune reactions. By adding the sample to a reagent card and then passing it through relevant chromatography detection equipment, test results can be obtained quickly. They are characterized by simple operation, high efficiency and speed, and are widely used in fields such as medical and epidemic prevention, food safety and environmental monitoring, and are showing an upward trend.

[0003] Currently, commonly used testing instruments mainly fall into two categories: colloidal gold card readers and immunofluorescence analyzers. These two types of equipment have only a single function, low integration, and incomplete data collection. Daily management requires distinguishing and labeling two different reagent cards, which is tedious, error-prone, and inefficient. Furthermore, since most tests require incubation, which can take anywhere from 3-5 minutes to 15-20 minutes, a dedicated temperature-controlled incubator is necessary. Therefore, existing immunoassay testing laboratories need to be equipped with multiple devices, including colloidal gold card readers, immunofluorescence analyzers, and temperature-controlled incubators, to meet daily testing needs. This results in problems such as limited functionality, long testing times, and large equipment size, making them inconvenient to carry.

[0004] Patent document CN106855515B discloses an integrated instrument for colloidal gold fluorescence quantitative analysis and its control method. This technical solution integrates two methods, colloidal gold detection and fluorescence chromatography detection, into one instrument. It mainly uses an imaging unit to optically photograph the reagent card. By judging whether the gray values ​​of the control line and the detection line of the reagent card can be obtained in the captured image, the corresponding detection mode is selected. If neither gray value is obtained, the fluorescence chromatography detection mode is entered; otherwise, the colloidal gold detection mode is entered. This improves the integration of the detection equipment. However, when the reagent card is moved for detection, the reagent card enters and exits the detection position in a horizontal direction, that is, the reagent card is perpendicular to the direction of movement. This makes the device bulky and difficult to carry. In addition, when the size of the reagent card is inconsistent, there is also the problem of inaccurate detection position positioning.

[0005] Patent document CN206756836U discloses a semi-automatic immunochromatographic analyzer with a constant temperature mechanism, including heating resistance wires and cooling semiconductors evenly distributed within the housing. Temperature sensors are located on both sides of the housing. This integrates and automates colloidal gold detection, fluorescence chromatography detection, and constant temperature incubation, greatly simplifying the detection operation. When transferring reagent cards for detection, the reagent cards enter and exit the detection position in a vertical position, parallel and overlapping with the direction of movement. This solves the problem of inaccurate detection positioning caused by inconsistent reagent card sizes and saves equipment space. However, due to the use of a turntable structure, the equipment is still bulky and difficult to carry. Furthermore, during the incubation of reagent cards on the turntable, the mechanical structure and electronic components inside the housing are affected by temperature. The low integration of the equipment not only increases power consumption but also accelerates equipment aging and wear.

[0006] In summary, existing technologies suffer from problems such as large device size, making them difficult to carry when traveling; furthermore, the devices have limited functionality and low integration, leading to accelerated aging and increased wear and tear. Utility Model Content

[0007] To address the problems in related technologies, this application discloses a multifunctional portable single-channel detection device that integrates colloidal gold detection, fluorescence detection, and constant temperature incubation functions using a constant temperature incubation box and a mobile positioning mechanism. This makes the device multifunctional, miniaturized, and portable, with a simple structure that is easy to mass-produce.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] A multifunctional portable single-channel detection device includes a housing with a detection port and an incubation port. Inside the housing are a fluorescence immunoassay component, a colloidal gold detection component, a constant temperature incubation box, a motion positioning mechanism, a microprocessor, and a touch screen. A reagent card can be placed into the constant temperature incubation box through the incubation port. The reagent card can be transferred to the fluorescence immunoassay component or the colloidal gold detection component for detection by the motion positioning mechanism through the detection port. The microprocessor is electrically connected to other components, and the touch screen enables human-computer interaction.

[0010] By adopting the above technical solution

[0011] During testing, the reagent card is first moved through the detection port by the mobile positioning mechanism to the bottom of the colloidal gold detection component by the QR code on the reagent card. The test items contained in the QR code are automatically obtained through photography and image recognition, and it is confirmed whether the test item is a colloidal gold test item or a fluorescence immunoassay test item. According to the test item, the mobile positioning mechanism moves the reagent card so that the test area on the reagent card is directly under the colloidal gold detection component or the fluorescence immunoassay component for the corresponding reagent test. After the test is completed, the mobile positioning mechanism moves the reagent card back to the initial position, and the test results are sent to the microprocessor for storage and displayed on the touch screen.

[0012] When incubating, insert the reagent card into the card slot of the constant temperature incubation box, set the incubation time through the touch screen, and the constant temperature incubation will be completed automatically.

[0013] The incubation and testing operations are relatively independent and do not interfere with each other.

[0014] As a further embodiment of this application, the constant temperature incubation box is composed of a back plate, an upper plate, and a lower plate. A heater and a temperature sensor are mounted on the upper surface of the upper plate, and a through-hole is provided on the lower plate. A position sensor is mounted on the back plate, connected to the end of the slot, and the incubation port is connected to the front end of the slot. This structure is simple, easy to manufacture and assemble. The position sensor can detect whether the reagent card is inserted into the slot, and the temperature, incubation time, and other information can be set via a touch screen, automatically starting the constant temperature incubation of the reagent card.

[0015] As a further aspect of this application: the lower plate has multiple card slots arranged in a horizontal row, with position sensors corresponding to each card slot. The incubation time for each card slot can be set individually via a touch display screen, saving incubation time; the horizontal arrangement of the card slots facilitates processing and makes it easy to retrieve reagent cards.

[0016] As a further aspect of this application: the position sensor is a reflective optocoupler module, the heater is a flexible electric heating film heating element, and the upper and lower plates are thin metal plates, specifically aluminum plates. The thin metal plates facilitate rapid temperature control and precise temperature regulation within the incubator. This structure is simple, reliable, and occupies a small volume, offering high temperature control accuracy and minimal impact on the temperature of other structures.

[0017] As a further aspect of this application: the mobile positioning mechanism includes a card holder, a transmission belt, a stepper motor, a sliding guide rail, and a sliding block. The sliding block is fixedly connected to the transmission belt, movably connected to the sliding guide rail, and fixedly connected to the card holder. The card holder is provided with a card tray, on which the reagent card can be placed to enter or exit the housing through the detection port. This structure helps the stepper motor to rotate precisely and moves the reagent card accurately to a predetermined position (such as a detection position or a barcode scanning position) using linear movement, facilitating rapid and accurate positioning during movement.

[0018] As a further aspect of this application: the card holder is also provided with a card holder positioning mechanism, which includes a positioning optical coupler detection module and a positioning block. The positioning optical coupler detection module is set on the housing, and the positioning block is set on the card holder. When the card holder is in the initial position, the positioning block is located inside the positioning optical coupler detection module. This structure is simple and the sensing information is sensitive and accurate.

[0019] As a further aspect of this application, a card tray sensor is also provided inside the housing. The card tray sensor can detect whether a reagent card is inserted into the card tray. The card tray sensor is a reflective optocoupler module. The microprocessor automatically executes corresponding operations based on the different states detected by the card tray sensor, such as automatic detection state or standby state. This structure improves the degree of automated detection.

[0020] As a further aspect of this application: the housing also includes a test head mounting bracket, with the colloidal gold detection component and the fluorescence immunoassay component symmetrically arranged on both sides of the test head mounting bracket, suspended above the card tray's movement path; the colloidal gold detection component has an imaging port at its bottom, through which the reagent card can be detected; the fluorescence immunoassay component has a laser hole at its bottom, through which the reagent card can be detected. This structure, by symmetrically mounting the colloidal gold detection component and the fluorescence immunoassay component on both sides of the test head mounting bracket, and then placing the test head mounting bracket on the housing, facilitates the rapid placement of the colloidal gold detection component and the fluorescence immunoassay component above the card tray's movement path, ensuring that the reagent card moves with the card tray to the detection area of ​​the colloidal gold detection component or the fluorescence immunoassay component, simplifying the installation and debugging process, making it easy to install and providing high calibration accuracy.

[0021] As a further aspect of this application, the housing also includes a photoelectric barcode scanner and a scanning window. The photoelectric barcode scanner is attached to the scanning window, and it scans the calibration curve information of the reagent card through the scanning window. This structure uses QR code scanning to obtain the calibration curve information of the reagent card, which is simpler and eliminates the need for an ID card compared to using an ID card via USB port. It is also lower in cost and more portable.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] 1. By recognizing the QR code to determine the detection method, the device automatically selects and completes colloidal gold detection or fluorescence chromatography detection, and sets up a constant temperature incubation box, enabling the device to achieve multi-functional integration and a high degree of automation.

[0024] 2. The use of colloidal gold detection components and microprocessors to replace photoelectric scanners for QR code scanning and recognition not only saves components but also combines the QR code scanning area with the colloidal gold detection area, making installation and positioning more convenient and faster.

[0025] 3. The test head mounting bracket facilitates quick installation, positioning, and calibration of the colloidal gold detection component, fluorescence immunoassay component, and card tray, ensuring that the colloidal gold detection component and fluorescence immunoassay component are suspended in the reagent card's movement path.

[0026] 4. The constant temperature incubation box, colloidal gold detection component, and fluorescence immunoassay component all adopt a modular design, which makes the incubation functional area and the detection functional area relatively independent and do not interfere with each other, reducing the risk of device aging; and by removing corresponding functional modules, customized equipment with different functions can be quickly integrated, which is conducive to mass production and manufacturing and reduces production costs.

[0027] 5. The card holder moves linearly along the sliding guide rail, and the reagent cards are placed vertically to maintain the same direction as the card tray. These features include a compact design, modular functions, and a horizontal row of card slots, which saves space and facilitates functional zoning and positioning.

[0028] 6. The initial position coordinates of the card tray are determined by the card slot positioning mechanism, and the card tray is moved and measured by the moving positioning mechanism. The method of origin positioning and moving distance measurement is used to accurately locate the position coordinates of the reagent card. The positioning and calibration can be repeated during use, and the displacement of the reagent card is accurate during the detection process. Attached Figure Description

Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects disclosed in this embodiment as detailed in the appended claims.

[0043] It should be noted that all directional indicators in the embodiments (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0044] Furthermore, the use of terms such as "first" and "second" in the embodiments is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit this application. It is merely to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0045] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0046] like Figure 1 , Figure 2 , Figure 9 As shown, a multifunctional portable single-channel detection device includes a housing 1, which has a detection port 11 and an incubation port 12. Inside the housing 1 are a fluorescence immunoassay component 3, a colloidal gold detection component 4, a constant temperature incubation box 5, a motion positioning mechanism 6, a microprocessor 7, and a touch screen 8. A reagent card can be placed into the constant temperature incubation box 5 through the incubation port 12. The reagent card can be transferred to the fluorescence immunoassay component 3 or the colloidal gold detection component 4 by the motion positioning mechanism 6 through the detection port 11 for detection. The microprocessor 7 is electrically connected to other components, and the touch screen 8 enables human-computer interaction.

[0047] like Figure 3 As shown, the constant temperature incubation box 5 is formed by a back plate 51, an upper plate 52 and a lower plate 53. The upper surface of the upper plate 52 is provided with a heater 54 and a temperature sensor (not marked in the figure). The lower plate 53 is provided with a slot 57 that runs through the front and back. The back plate 51 is provided with a position sensor 55, which is connected to the end of the slot 57. The incubation port 12 is connected to the front end of the slot 57.

[0048] The reagent card is inserted into the card slot 57 through the incubation port 12. When the position sensor 55 at the end of the card slot 57 detects the reagent card, it sends a signal to the microprocessor 7. The microprocessor 7 controls the touch screen 8 to display the position and status of the corresponding card slot 57 and the parameter information to be set. After the operator inputs the incubation time, temperature and other parameter information, the constant temperature incubation will start automatically. After the incubation is completed, the operator will be notified of the completion of incubation through voice, image, sound and light.

[0049] There are multiple card slots 57 arranged in a horizontal row, making it convenient to retrieve reagent cards daily. Position sensors 55 are set one-to-one with card slots 57. This structure of card slots 57 and position sensors 55 forms a relatively independent incubation unit, so that the incubation operations between multiple card slots 57 are relatively independent and do not interfere with each other. This not only facilitates the production and manufacturing of the lower plate 53, but also makes it easy to miniaturize the constant temperature incubation box 5.

[0050] The position sensor 55 is a reflective optocoupler module, which has a simple structure and provides a stable and accurate sensing signal; the heater 54 is a flexible electric heating film heating element, which saves space and is easy to control precisely.

[0051] The upper plate 52 and the lower plate 53 are thin metal plates. The metal material is conducive to heat conduction and can quickly achieve constant temperature incubation. The thin metal plates are aluminum plates, which helps to reduce costs.

[0052] like Figure 2 , Figure 4 , Figure 5 As shown, the moving positioning mechanism 6 includes a card holder 2, a transmission belt 61, a stepper motor 62, a sliding guide rail 63, and a sliding block 64. The sliding block 64 is fixedly connected to the transmission belt 61, movably connected to the sliding guide rail 63, and fixedly connected to the card holder 2. A card tray 21 is provided on the card holder 2, and reagent cards can be placed on the card tray 21 to enter or exit the housing 1 through the detection port 11. When the stepper motor 62 is started, the transmission belt 61 rotates, and the transmission belt 61 drives the sliding block 64 to move linearly along the sliding guide rail 63. The sliding block 64 drives the card holder 2 and the card tray 21 to move together, and the reagent card is placed on the card tray 21 and moves linearly together.

[0053] Card holder 2 also includes card holder positioning mechanism 23, which includes positioning optical coupler detection module 24 and positioning block 25. Positioning optical coupler detection module 24 is disposed on housing 1, and positioning block 25 is disposed on card holder 2. When card holder 2 is in the initial position, positioning block 25 is located within positioning optical coupler detection module 24. Microprocessor 7 can obtain the initial position (i.e., origin coordinates) of card holder through card holder positioning mechanism 23, accurately measure the moving path of moving positioning mechanism 6, and thus control card tray 21 to accurately transfer reagent card to the predetermined position.

[0054] The housing 1 also contains a card tray sensor 22, which can detect whether a reagent card is inserted into the card tray 21. The card tray sensor 22 is a reflective optocoupler module. When the microprocessor 7 receives a signal from the card tray sensor 22 indicating that a reagent card has been inserted into the card tray 21, the detection is automatically activated.

[0055] like Figure 2 , Figure 6 , Figure 7 As shown, the housing 1 is also equipped with a test head mounting bracket 9, and the colloidal gold detection component 4 and the fluorescence immunoassay component 3 are arranged on both sides of the test head mounting bracket 9. The colloidal gold detection component 4 and the fluorescence immunoassay component 3 are suspended above the moving path of the card tray 21. The bottom of the colloidal gold detection component 4 is provided with an imaging port 41. The bottom of the fluorescence immunoassay component 3 is provided with a laser hole 31.

[0056] When the QR code area of ​​the reagent card is moved by the moving positioning mechanism 6 to below the colloidal gold detection component 4, the camera port 41 faces the QR code area of ​​the reagent card to take a picture and recognize the QR code; when the detection area of ​​the reagent card is moved by the moving positioning mechanism 6 to below the colloidal gold detection component 4, the camera port 41 faces the detection area of ​​the reagent card to perform colloidal gold detection; when the detection area of ​​the reagent card is moved by the moving positioning mechanism 6 to below the fluorescence immunoassay component 3, the laser hole 31 faces the detection area of ​​the reagent card to perform colloidal gold detection.

[0057] like Figure 2 , Figure 8 As shown, the housing 1 also includes a photoelectric barcode scanner 10 and a scanning window 13. The photoelectric barcode scanner 10 is attached to the scanning window 13, and the photoelectric barcode scanner 10 scans the calibration curve information of the reagent card through the scanning window 13. This structure can import the calibration curve information of the reagent card without the need for a separate ID card, which is convenient, fast, and easy to move around.

[0058] The housing 1 also contains a communication module (not shown in the attached diagram). The communication module includes various communication modules such as RS232, USB, LAN, and 4G. The microprocessor 7 can perform wireless or wired communication through the communication module to realize remote data exchange. It can also be conveniently connected to the data center when carried out.

[0059] The housing 1 also contains a printer (not shown in the attached diagram), which can print out the test results in real time for viewing and saving, making it convenient for use when going out.

[0060] The implementation principle of a multifunctional portable single-channel detection device according to an embodiment of this application is as follows:

[0061] I. Constant temperature incubation

[0062] The components related to the constant temperature incubation function include the constant temperature incubation box 5. Before the constant temperature incubation begins, all relevant components are in their initial state. At this time, there is no reagent card in the card slot and the heater is not working.

[0063] Insert the reagent card to be incubated into the card slot 57. After the position sensor 55 at the end of the card slot 57 senses the reagent card, the touch screen 8 pops up the corresponding interface, displays the status of the corresponding card slot 57, and prompts the user to input the corresponding parameter information (such as incubation time). After the operator completes the relevant parameter settings, the microprocessor 7 starts the heater 54 and performs constant temperature incubation based on the real-time signal sensed by the temperature sensor. After incubation is completed, the microprocessor 7 reminds the operator to take out the reagent card that has completed incubation in time through voice, sound, light and image.

[0064] When multiple reagent cards are inserted into each slot 57, the incubation time of each reagent card in each slot 57 can be set. The working status of each slot 57 is relatively independent. The microprocessor 7 monitors the incubation status of each reagent card in each slot 57 and reminds the operator to take out the reagent card that has completed incubation in time through voice, light and image.

[0065] Once all reagent cards have been removed, the microprocessor 7 notifies the heater 54 to stop working, and the relevant components for constant temperature incubation return to their initial state.

[0066] II. Chromatographic Detection

[0067] Components related to the chromatography detection function include the fluorescence immunoassay component 3, the colloidal gold detection component 4, and the motion positioning mechanism 6. Before the chromatography detection begins, all relevant components are in their initial state, at which time the front end of the card tray 21 is located outside the housing 1 through the detection port 11.

[0068] Step 1: Identification of Detection Items

[0069] When the reagent card to be tested is inserted into the card tray 21, the card tray sensor 22 detects the insertion of the reagent card, and the microprocessor 7 notifies the moving positioning mechanism 6 to start the stepper motor 62, causing the conveyor belt 61 to rotate, which drives the sliding block 64 and the card holder 2 to move linearly along the sliding guide rail 63. The reagent card moves into the housing 1 along with the card tray 21 until the colloidal gold detection component 4 is suspended above the QR code graphic on the reagent card. The QR code image is captured through the shooting port 41 of the colloidal gold component 4, and the image is processed by the microprocessor 7 to obtain the QR code information, thereby obtaining the test items of the reagent card and the test method to be used.

[0070] Step 2, Automatic Detection

[0071] Following step 1, based on the obtained detection items and the detection methods to be adopted, the microprocessor 7 instructs the motion positioning mechanism 6 to start, activate the stepper motor 62, and cause the conveyor belt 61 to rotate, driving the sliding block 64 and the card holder 2 to move linearly along the sliding guide rail 63. The reagent card moves linearly along with the card holder 21 until the imaging port 41 of the colloidal gold detection component 4 or the laser hole 31 of the fluorescence immunoassay component 3 is suspended above the detection area of ​​the reagent card. At this point, the motion positioning mechanism 6 stops working, the colloidal gold detection component 4 or the fluorescence immunoassay component 3 begins chromatography detection, and the microprocessor 7 receives the detection data and displays it on the touch screen.

[0072] Step 3: Return to the initial state

[0073] After the test is completed, the microprocessor 7 instructs the moving positioning mechanism 6 to operate. The stepper motor 62 drives the conveyor belt 61 to rotate in the opposite direction, causing the reagent card to move towards the detection port 11 along with the card holder 21. When the positioning optocoupler detection module 24 senses the positioning block 25, the microprocessor 7 confirms that the card holder 2 has returned to its initial position, and the moving positioning mechanism 6 stops operating. At this time, the front end of the card holder 21 protrudes outside the detection port 11. When the operator removes the reagent card from the card holder 21, the card holder sensor 22 detects that the reagent card has been removed, and all components related to the chromatography detection function return to their initial state.

[0074] III. Importing Reagent Card Information

[0075] When the QR code graphic carrying the calibration curve information of the reagent card is aligned with the scanning window 13 on the housing 1, the photoelectric scanner 10 automatically obtains the QR code information through the scanning window 13 and sends it to the microprocessor 7. The microprocessor 7 automatically performs the corresponding information processing and data storage.

[0076] In practical applications, manufacturers may encounter customized needs from customers regarding different combinations of functions. This application can be tailored to these specific needs by simply adjusting the equipment assembly process. For example, if the customer does not require the colloidal gold detection function, a photoelectric barcode scanner can be used to replace the colloidal gold detection component; if the customer does not require the fluorescence chromatography detection function, the fluorescence chromatography detection component can be omitted; and if the customer does not require the constant temperature incubation function, the constant temperature incubation box can be omitted. This structure is beneficial for large-scale mass production.

[0077] Finally, it should be noted that the above disclosure is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. The scope of this application is limited only by the appended claims.
