The solid-liquid flash Helicobacter pylori detector 10 comprises a housing 100, a display screen 110 is mounted on the outer surface of the housing 100, and an opening 120 for loading or removing a sample bottle is provided. A scanner 130 for scanning label information of the sample bottle and transmitting the label information to the display screen 110 for display is also mounted in the housing 100; a sample tray assembly 200, inserted into the opening 120 and is drawn and arranged in the inner cavity of the shell 100, for placing the sample bottles to be tested and the sample bottles that have not passed the code scanning; a plurality of measuring chambers 300 are respectively arranged in the inner cavity of the shell 100 and are used to detect the samples in the sample bottles; a motion control unit 400 includes a clamping jaw 410 for clamping the sample bottle, a traction assembly 420 for driving the clamping jaw 410 to move in the three-dimensional space of the inner cavity of the shell 100, a driving motor group 430 for driving the traction assembly 420 to move, and a controller 440 for controlling the operation of the driving motor group 430, the clamping jaw 410 is in the traction assembly 420 Under the action of the scanner 130, the sample bottle is transported to the scanner 130 for scanning and sent into the corresponding measuring chamber 300 in sequence for detection; the signal processing unit 500, including the signal processing board 510, is used to process the measurement information from the measuring chamber 300 and the corresponding sample bottle label information, and send the processed sample bottle label information and its corresponding measurement results to the display screen 110 for display. Specifically, each measurement information corresponds to a label information; and the power supply 600 is used to power the detector 10.

[0022] The solid-liquid flash Helicobacter pylori detector 10 of the present invention can load a large number of sample bottles into the sample tray assembly 200 at one time, and the sample bottles in the sample tray assembly 200 are grasped in sequence by the clamping claw 410, and the sample bottles are carried to the scanner 130 for scanning and identification, and then the sample bottles that have successfully scanned are placed in a measuring chamber 300 for Helicobacter pylori marker detection. While the detection operation is being carried out in one measuring chamber 300, the clamping claw 410 sequentially grasps the sample bottles in the sample tray assembly 200 and puts them one by one into other measuring chambers 300 for testing. In this way, multiple measuring chambers 300 alternately detect the samples in each sample bottle, which significantly improves the detection efficiency of the detector 10; the traction assembly 420 is used to drive the clamping claw 410 to automatically grasp the sample bottle, which improves the sampling efficiency, further improves the detection efficiency and reduces the detection cost; the scanner 130 is used The signal processing board 510 respectively collects the barcode information of the sample bottle and the measurement results of the sample bottle in the measuring room, thereby avoiding the occurrence of data misrecording or omission problems and improving the reliability of the detection results.

[0023] The housing 100 is used to accommodate the sample tray assembly 200, the measuring chamber 300, the motion control unit 400, the signal processing unit 500 and the power supply 600, etc., to achieve packaging protection for the above components and provide a detection space for the detection of the sample in the sample bottle. Figure 1 and Figure 3 In one embodiment, a plurality of heat dissipation holes 140 are provided on the side sealing plate of the shell 100, and a heat-conducting fan 141 is provided in the inner cavity of the shell 100 adjacent to the heat dissipation holes 140. It should be noted that the side sealing plate of the present embodiment is located on the shell 100 adjacent to the bottom of the shell 100, so as to be removed and the components in the shell 100 can be inspected and repaired when the equipment fails. Specifically, during the operation of the detector 10, the heat-conducting fan 141 is connected to the current, the motor of the heat-conducting fan 141 rotates rapidly and drives the shaft and the fan blades to stir the air around it, so that the air pressure around the fan blades drops. In this way, the heat generated by the operation of each component will flow to the heat-conducting fan 141 driven by the airflow, and be discharged through the heat dissipation holes 140, thereby achieving heat dissipation of the detector 10 and avoiding the problem of component damage caused by continuous high heat of the components in the shell 100, so as to extend the service life of the detector 10. Please refer to the following examples in conjunction with Figure 1 and Figure 3 In one embodiment, a relay 150 for controlling the start and stop of the detector 10 is provided in the housing 100, and a hand control 160, such as a control button, for triggering the action of the relay 150 is installed on the housing 100. Specifically, when the sample bottle to be tested is loaded into the sample tray assembly 200, the hand control 160 is pressed and the relay 150 is triggered to start the instrument normally.

[0024] It should be noted that the scanner 130 and the signal processing board 510 of the present invention can also be electrically connected or data connected to an external host computer 520, such as a microcomputer, respectively, and the external host computer 520 is further connected to the display screen 110, so as to organize and calculate the label information and the measurement information to obtain the data results in the format expected by the user. In actual production, the external host computer 520 can be accommodated in the inner cavity of the housing 100 to achieve integrated management of the equipment. In actual production, a mouse and a keyboard electrically connected to the host computer 520 can also be configured to input instructions to the host computer 520, so that the user can input a specific program into the host computer 520 through the keyboard and perform calculation processing on the test results, so as to obtain a predetermined test result. It should be noted that the host computer 520 does not belong to the necessary mechanism of the detector 10 of the present invention. The description of the host computer 520 here is intended to explain a kind of information processing method of the detector 10, which will not be repeated here.

[0025] See also Figure 3 In one embodiment, the housing 100 is provided with a USB interface 170 and / or a network cable interface electrically connected to the scanner 130 and the signal processing board 510, respectively, for realizing data connection or communication connection between the detector 10 and the external processor. Specifically, during the use of the detector 10, the detector 10 can be electrically connected to external devices, such as keyboards, mice and other peripheral devices, through a data connection line inserted in the USB interface 170 to realize control of the host computer 520; the detector 10 can also be connected to a cloud server or other intelligent terminal through a network cable inserted in the network cable interface to realize long-distance data transmission and remote control of the detector 10, thereby improving the flexibility of device control.

[0026] See also Figure 5 In one embodiment, a telescopic rod 180 is further provided at the bottom of the housing 100, which is used to provide a gripping portion for carrying the detector 10 in the pulled-out state. Specifically, when carrying the detector 10, the telescopic rod 180 is pulled out from the bottom of the housing 100, so that the operator can lift the detector 10 by gripping and lifting the telescopic rod 180, which is convenient for moving the detector 10. In this process, the telescopic rod 180 is used to provide a fulcrum for moving the detector 10, so as to reduce the difficulty of carrying the detector 10. After the carrying operation of the detector 10 is completed, the end of the telescopic rod 180 is pushed to retract the telescopic rod 180, thereby reducing the overall length of the telescopic rod 180, so as to avoid injuries caused by accidental contact with the end of the telescopic rod 180 during the use of the detector 10, so as to improve the safety of the detection operation.

[0027] The sample tray assembly 200 is used to place the sample bottles to be tested and the sample bottles after testing, so as to facilitate the centralized sampling of the sample bottles. Figure 2In one embodiment, the sample tray assembly 200 includes a plurality of drawer grids 210 arranged side by side, each drawer grid 210 is provided with a plurality of receiving slots for receiving sample bottles, and a handle 220 for holding the drawer grid 210 is provided at one end of each drawer grid 210 away from the inner cavity of the housing 100. Furthermore, the detector 10 also includes a lock group 700 for opening and closing the sample tray assembly 200 and a pump valve module 800 for controlling the operation of the lock group 700. Specifically, before the detection operation is carried out, the pump valve module 800 is controlled to work, and the lock group 700 is opened by the pump valve module 800 to release the lock of the sample tray assembly 200. In this way, the operator only needs to pull the handle 220 to take out the entire drawer grid 210 from the inner cavity of the shell 100, so as to facilitate the installation of the sample bottle to be tested in the drawer grid 210; after the sample bottle is installed, the drawer grid 210 is pushed into the inner cavity of the shell 100 through the opening 120, and then the pump valve module 800 is controlled to operate again to drive the lock group 700 to lock, thereby limiting each drawer grid 210 to avoid the drawer grid 210 being pulled out of the shell 100 due to misoperation during the detection operation, so as to ensure the effective implementation of the sample detection operation in the sample bottle. In this embodiment, the lock group 700 used to control the opening and closing of the sample tray assembly 200 is a common mechanical lock group 700 available on the market. The pump valve module 800 used to control the action of the lock group 700 can be either a pneumatic pump valve or an electric pump valve. Of course, in actual production, a sensor can be used to automatically sense that the drawer grid 210 is stored and send instructions to the pump valve module 800 to control the action of the lock group 700. Other forms of lock control devices can also be used, which will not be repeated here.

[0028] In one embodiment, the sample tray assembly 200 includes a sample placement area for samples that have passed the code scanning and an abnormal sample placement area. The abnormal sample placement area is used to place sample bottles with incorrect code scanning, or is used as a temporary placement area for sample bottles when the detector fails or loses power or is in a shutdown state. Specifically, the sample tray assembly 200 includes at least one drawer grid 210 for placing abnormal samples. In this way, after the clamp 410 grasps the sample bottle and scans it at the scanner 130, if the scanner 130 does not scan the corresponding barcode information, that is, it is determined that there is no barcode attached to the sample bottle or the barcode is damaged. In this case, the scanner 130 displays the damaged abnormal information on the display screen 110; at the same time, the scanner 130 also transmits the abnormal information to the controller 440. After receiving the abnormal information, the controller 440 adjusts the drive motor group 430 and the traction assembly 420, and then adjusts the movement path of the clamp 410, so that the clamp 410 places the abnormal sample bottle into the drawer grid 210 of the abnormal sample placement area, so as to ensure that the barcode of the sample bottle entering the measuring chamber 300 is valid, and it is conducive to centralized processing of sample bottles with abnormal barcodes.

[0029] Furthermore, in one embodiment, a sensor 900 is provided in the housing 100 for detecting the state of the sample bottles in the abnormal sample placement area. Specifically, the sensor 900 includes a transmitting end and a reflecting end provided at both ends of the drawer compartment 210. After the sensor 900 is powered on, when there are sample bottles in the drawer compartment 210, the signal emitted by the transmitting end of the sensor 900 is blocked by the sample bottles there, and it is difficult to reach its reflecting end to be reflected and recovered. The sensor 900 determines that there are sample bottles in the abnormal sample placement area, and then sends a signal to the external host computer 520 or a data receiving device with an alarm device, so as to prompt the user that the sample bottles in the abnormal sample placement area have not been completely taken out, so as to facilitate the effective implementation of the sample bottle taking and placing operation.

[0030] The measuring chamber 300 is used to measure the sample in the sample bottle, specifically, to measure the marked 14 C, when the detector 310 in the measuring chamber 300, such as a photomultiplier tube, detects 14 When C reacts with the scintillation material in the sample bottle and generates fluorescence, the photomultiplier tube amplifies the detected light signal and converts it into an electrical signal output. The output electrical signal is transmitted to the signal processing board 510. After the signal processing board collects, analyzes and processes relevant data, the electrical signal is further sent to the display screen 110, or after being calculated by the host computer 520, it is displayed on the display screen 110 again in the form of a corresponding digital signal or image signal, thereby obtaining the detection result of the sample in the specific sample bottle. The signal processing board 510 cooperates with the photomultiplier tube to realize 14 Qualitative analysis of C marker content. Figure 6 In one embodiment, the measuring chamber 300 includes a box body 320 and a bottom sealing plate 330 that can be opened and closed on the housing 100. The detector 310 is installed in the inner cavity of the box body 320. Before the detection operation, the bottom sealing plate 330 is opened to facilitate the placement of the sample bottle into the box body 320. Then, the bottom sealing plate 330 is closed so that the sample bottle is detected in a closed space to prevent the light outside the box body 320 from interfering with the operation of the detector 310, thereby ensuring the reliability of the detection result. Furthermore, a top sealing plate 340 is provided on the side of the bottom sealing plate 330 that faces away from the box body 320, which is used to block the gap between the bottom sealing plate 330 and the box body 320, thereby improving the light-blocking effect of the measuring chamber 300.

[0031] The motion control unit 400 is used to control and adjust the motion path of the sample bottle to execute the detection process of the sample in the sample bottle. In one embodiment, the traction assembly 420 includes a first guide rail 421 extending along the length direction of the housing 100, a second guide rail 422 extending along the width direction of the housing 100 and slidably connected to the first guide rail 421, a third guide rail 423 extending along the height direction of the housing 100 and slidably connected to the second guide rail 422, and a traction head 424 installed on the third guide rail 423 and raised and lowered relative to the third guide rail 423, and the clamp 410 is installed on the traction head 424. In this way, when the driving motor group 430 works under the control of the controller 440, the second guide rail 422 slides relative to the first guide rail 421 driven by the driving motor group 430, the third guide rail 423 slides relative to the second guide rail 422 driven by the driving motor group 430, and the traction head 424 slides relative to the third guide rail 423 driven by the driving motor group 430. In this way, the clamping jaw 410 moves in the horizontal plane and the vertical plane at the same time under the combined action of the driving motor group 430 on each guide rail and the traction head 424. The clamping jaw 410 moves in the three-dimensional space within the guide rail length range of each guide rail. The clamping jaw 410 can reach any position in the three-dimensional space surrounded by the ends of each guide rail, so as to adjust the position of the sample bottle.

[0032] The driving motor group 430 is used to drive the corresponding guide rails and the traction head 424 of the traction assembly 420 to move, so as to adjust the position of the clamping jaw 410. It should be noted that the driving motor group 430 of this embodiment includes a plurality of servo motors that respectively drive the guide rails and the traction head 424. The servo motor has a high working accuracy and can realize closed-loop negative feedback regulation, which is conducive to ensuring the movement accuracy of the clamping jaw 410, thereby improving the reliability of the sample bottle taking and placing operation.

[0033] The signal processing unit 500 is used to record the test results of the sample in the sample bottle. In one embodiment, the signal processing unit 500 also includes a filter device 530 for removing interference signals. Specifically, the filter device is used to filter out interference signals on the power supply, suppress high-frequency components or interference and noise, and improve safety and EMC performance.

[0034] In one embodiment, a status display light 190 is provided on the housing 100 to indicate the detection progress of the sample bottle. Preferably, the status display light 190 includes a plurality of LED modules, each LED chip corresponds to a drawer compartment 210, and is used to display the processing status of the sample bottle in the corresponding drawer compartment 210. Specifically, when the sample detection in the drawer compartment 210 corresponding to the LED chip is completed, the LED module lights up and displays green, when the sample in the drawer compartment 210 corresponding to the LED module is being detected, the LED module lights up and displays blue, and when the drawer compartment 210 corresponding to the abnormal sample placement area has a sample placed in it, the LED module corresponding to the drawer compartment 210 lights up and presents yellow. It should be noted that the display color of the LED module in different states of the detector 10 can be adjusted according to user needs, and the indication of the state in the drawer compartment 210 and the display of the LED module are determined by the position coordinates of the sample. For example, when the clamp 410 drives the sample into the abnormal sample placement area, the host computer 520 analyzes the position data and controls the corresponding LED module to light up.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
