TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a Helicobacter pylori measuring instrument. BACKGROUND

[0002] In order to accurately diagnose Helicobacter pylori infection, the medical field has developed various detection methods, among which the radioisotope detection method is widely used due to its high sensitivity and accuracy. However, the traditional radioisotope detection equipment is bulky, complex to operate, and requires professional personnel to operate and maintain, limiting its application in primary medical institutions and families.

[0003] Although the existing Helicobacter pylori detection equipment meets the clinical needs to some extent, there are still some deficiencies. For example, although the existing portable radioisotope detector is small in size, it is still not efficient in signal acquisition and processing, especially in processing complex radiation spectrum information, which is easily disturbed, resulting in inaccurate detection results. At the same time, the user interface of these devices is not user-friendly, and the operation is complex, requiring professional training to use it skillfully, which limits its application in a wider range of medical scenarios.

[0004] Therefore, there is an urgent need for a Helicobacter pylori measuring instrument that can efficiently and accurately process the energy spectrum information of the measured sample and is easy to operate. CONTENT OF THE INVENTION

[0005] The present application provides a Helicobacter pylori measuring instrument that can accurately measure Helicobacter pylori and is easy to operate.

[0006] In a first aspect, the present application provides a Helicobacter pylori measuring instrument, comprising a detector, a mainboard and a display screen, the mainboard is in communication connection with the detector and the display screen respectively, wherein:

[0007] The display screen is used for receiving a first instruction input by a user and transmitting the first instruction to the mainboard, receiving feedback information displayed by the mainboard and displaying the feedback information;

[0008] The mainboard is used for receiving and processing the first instruction transmitted by the display screen to generate a second instruction, transmitting the second instruction to the detector, receiving and processing the radiation spectrum information fed back by the detector to generate display information, and sending the display information to the display screen;

[0009] The detector is used for receiving the second instruction transmitted by the mainboard, and acquiring the radiation spectrum information in the gas collection card to be measured according to the second instruction, and transmitting the radiation spectrum information to the mainboard.

[0010] The first instruction input by the user is received through the display screen, and the display information fed back by the mainboard is displayed, so that the user can intuitively interact with the measuring instrument and understand the measurement results and related information during the measurement process. This design improves the ease of use and user experience of the measuring instrument. The mainboard, as the core component of the measuring instrument, is responsible for receiving and processing instructions from the display screen, as well as receiving and processing radiation spectrum information fed back by the probe. Through the efficient processing of the mainboard, the display information can be quickly generated and sent to the display screen, thereby improving the data processing speed and accuracy of the measuring instrument. The probe acquires the radiation spectrum information in the measured gas collection card according to the second instruction transmitted by the mainboard. Since the probe can accurately acquire the radiation spectrum information, the accuracy of the measurement results can be ensured. This design makes the measuring instrument have high precision and reliability in the detection of Helicobacter pylori. The various components of the measuring instrument are connected through communication for data transmission and processing, which makes the system have good stability and reliability. At the same time, the mainboard, as the central control component, can coordinate the work of each component to ensure the smooth progress of the entire measurement process.

[0011] Optionally, the probe comprises a plastic scintillator and a photomultiplier tube, wherein:

[0012] The plastic scintillator is used to acquire the radiation released by the decay of the preset element in the measured gas collection card to generate a fluorescent signal;

[0013] The photomultiplier tube is coupled with the plastic scintillator through optical silicon grease, and is used to perform photoelectric conversion and amplification on the fluorescent signal to generate a pulse signal.

[0014] The plastic scintillator, as the front-end component of the probe, can efficiently capture the preset element (such as 14C) After the decay of the released rays. These rays interact with the plastic scintillator, and then excite the fluorescence signal, providing a reliable signal source for subsequent measurement. The photomultiplier tube is tightly coupled with the plastic scintillator through optical silicon grease, ensuring that the fluorescence signal can be efficiently transferred to the photomultiplier tube. The photomultiplier tube has extremely high sensitivity and gain, which can convert the weak fluorescence signal into an electrical signal and amplify it greatly, thereby generating a pulse signal that is easy to process and measure. Due to the close coupling of the plastic scintillator and the photomultiplier tube, as well as the high sensitivity of the photomultiplier tube, the detector can accurately capture and convert the fluorescence signal generated by the rays, thereby generating a high-precision pulse signal. This helps to improve the detection accuracy and accuracy of the measurement instrument for Helicobacter pylori. The stability and reliability of the plastic scintillator and the photomultiplier tube as the core components of the detector are crucial to the stability of the entire measurement system. Through careful design and manufacturing, as well as reasonable coupling methods, the stability of the detector can be ensured during long-term operation, thereby improving the stability and reliability of the entire measurement system. The efficient, accurate and stable operation of the detector enables the measurement instrument to quickly and accurately provide measurement results, thereby optimizing the user experience. Users can intuitively understand the measurement results through the display screen and perform subsequent operations or analysis as needed.

[0015] Optionally, the mainboard is further configured to:

[0016] receive the pulse signal after the high-voltage direct-current isolation capacitor isolates the high voltage, and process the pulse signal to obtain the ray spectrum information of the gas collection card to be measured.

[0017] The signal processing circuit in the mainboard is configured to quickly sample the amplitude of each signal and save the ADC value of the amplitude in the energy spectrum array, so as to obtain the energy spectrum information of the measured object through a period of measurement.

[0018] The introduction of the high-voltage direct-current isolation capacitor effectively isolates the high-voltage component in the pulse signal, preventing potential damage to the mainboard circuit by the high-voltage signal, thereby protecting the safe operation of the mainboard and subsequent processing circuit. An efficient and stable signal processing flow helps to improve measurement efficiency. The mainboard can quickly and accurately process the pulse signal and generate ray spectrum information, thereby shortening the measurement period and improving work efficiency.

[0019] Optionally, the detector further comprises a metal shell, a high-voltage voltage dividing plate and a high-voltage shielding coaxial cable, wherein:

[0020] The metal shell is located outside the plastic scintillator and the photomultiplier tube to protect the plastic scintillator and the photomultiplier tube;

[0021] The high-voltage voltage dividing plate is configured to provide the required high voltage for the photomultiplier tube;

[0022] The high-voltage shielded coaxial cable is used to connect the main board and the detector, and is used to transmit high voltage and the pulse signal, and ensures the isolation between the high voltage and the pulse signal.

[0023] The metal shell is located outside the plastic scintillator and the photomultiplier tube, and plays a firm protection role. It can prevent external physical impact, vibration and pollution from damaging the sensitive components inside the detector, and ensure the stable operation and long-term use of the detector. The design of the high-voltage voltage dividing plate enables the photomultiplier tube to obtain a stable high-voltage supply. This is a necessary condition for the normal operation of the photomultiplier tube, because high voltage can accelerate photoelectrons, thereby improving photoelectric conversion efficiency and signal gain. Stable high-voltage supply helps to ensure the stability and consistency of the detector output signal. The high-voltage shielded coaxial cable is not only used to transmit high voltage and pulse signals, but also ensures effective isolation between high voltage and pulse signals and external devices. This isolation prevents high-voltage discharge, reduces interference and noise between signals, and improves the clarity and accuracy of signal transmission. At the same time, the high-voltage shielded coaxial cable also has good electromagnetic shielding performance, which can resist external electromagnetic field interference and protect the integrity of the signal. The cooperation of the metal shell and the high-voltage shielded coaxial cable effectively isolates the high voltage and pulse signal, reducing the risk of potential electric shock and short circuit. This improves the safety of the entire detector, making operation more reliable and worry-free. The metal shell and the modular design make it easier to maintain and replace the detector. When internal components need to be repaired or replaced, the shell can be easily opened and the corresponding parts can be accessed, reducing maintenance costs and difficulty.

[0024] Optionally, the detector further comprises a measurement chamber and a sample in-place sensor, wherein:

[0025] The measurement chamber is used to place the to-be-tested gas collection card.

[0026] The sample in-place sensor is used to monitor whether the to-be-tested gas collection card is placed in the measurement chamber, and feeds back the monitoring result to the main board.

[0027] The measurement chamber provides a stable and controllable measurement environment for the gas collection card to be measured. By ensuring that the gas collection card is in the correct position and state during the measurement process, the influence of external factors on the measurement results can be reduced, thereby improving the accuracy of the measurement. The sample in-place sensor can monitor in real time whether the measurement chamber has placed the gas collection card to be measured, and feed back the monitoring results to the mainboard. This automatic monitoring function makes the measurement process more intelligent and automated, reducing the dependence on manual operation and errors. The mainboard can automatically determine whether to start measurement or issue corresponding prompt information according to the feedback results of the sensor. The automatic monitoring function not only improves the accuracy of the measurement, but also enhances the user experience. The user does not need to manually confirm whether the gas collection card is placed correctly, and the system can automatically complete this step. At the same time, when the gas collection card is not placed correctly, the system can issue a prompt information to guide the user to perform the correct operation. Through the monitoring of the sample in-place sensor, the system can timely find that the gas collection card is not placed in the measurement chamber or is placed incorrectly, thereby avoiding invalid measurement or damaging the equipment in the absence of samples. This design enhances the safety and reliability of the system.

[0028] Optionally, the mainboard is further configured to:

[0029] performing logical judgment on the monitoring results of the sample in-place sensor, and if the gas collection card to be measured is not detected, suspending the measurement process and sending a prompt information to the display screen.

[0030] The mainboard can intelligently perform logical judgment on the monitoring results of the sample in-place sensor, and immediately suspend the measurement process when the gas collection card to be measured is not detected. This function effectively avoids invalid measurement in the absence of samples, thereby saving time and resources and improving measurement efficiency. When the system detects that the gas collection card is not placed in the measurement chamber, the mainboard sends a prompt information to the display screen. This instant feedback mechanism enables the user to quickly understand the current state and take appropriate measures, such as placing the gas collection card or checking the equipment. This improves the user's operation experience and reduces errors caused by improper operation or misunderstanding. By detecting the gas collection card before measurement, the system can ensure that it works under effective measurement conditions, thereby avoiding equipment damage or measurement errors caused by improper placement of the gas collection card. This design enhances the reliability and stability of the system.

[0031] Optionally, the H. pylori measurement instrument further comprises an instrument housing for carrying and fixing the probe, the mainboard and the display screen.

[0032] The instrument housing integrates the key components such as the probe, main board and display screen together, forming a complete and compact measurement system. This integration not only improves the overall integrity and aesthetics of the system, but also protects the internal components from external physical impact, vibration, dust and moisture, etc. by the protective effect of the housing, thereby prolonging the service life of the equipment. The fixing effect of the instrument housing ensures the stable connection and relative position between the components such as the probe, main board and display screen. This stability is crucial for the accurate measurement and stable operation of the measuring instrument, as any slight displacement or looseness may affect the accuracy of the measurement results. Through reasonable design, the instrument housing can make the entire measuring instrument more portable, easy to carry and operate. This is particularly important for users who need to measure at different locations, as they can easily carry the equipment to the site for measurement without worrying about the damage of the equipment or the inconvenience of operation.

[0033] Optionally, the H. pylori measuring instrument further comprises an indicator light and a measurement chamber door, wherein:

[0034] The indicator light is connected with the main board, and is used to display the working state of the instrument according to the indication signal of the main board, the working state including standby, measurement in progress, fault;

[0035] The measurement chamber door is arranged on the instrument housing at the opening of the measurement chamber, and is used to ensure that the measurement chamber is in a darkroom state when the measurement chamber door is closed.

[0036] The indicator light is connected to the mainboard and can reflect the working status of the instrument in real time, such as standby, measurement, fault, etc. This intuitive indication method enables users to quickly understand the current status of the instrument and take appropriate actions or measures. For example, when the indicator light shows that the instrument is in a fault state, the user can contact the maintenance personnel in time for repair, avoiding delay in measurement work. The design of the measurement chamber door ensures that the measurement chamber is in a dark room state when the door is closed. The dark room state is crucial for reducing the interference of external light on measurement, as external light may affect the sensitivity and accuracy of the detector. By ensuring that the measurement chamber remains in a dark room state during measurement, the accuracy and reliability of the measurement can be improved. The measurement chamber door also plays a role in protecting the measurement environment. It can prevent dust, moisture and other impurities from entering the measurement chamber, thereby maintaining the cleanliness and dryness of the measurement chamber. This is of great significance to ensure the accuracy of measurement results and prolong the service life of the equipment. The design of the indicator light and the measurement chamber door takes into account the usage habits and needs of users. The intuitive indication of the indicator light and the convenient operation of the measurement chamber door make it easier for users to use the instrument, thereby improving the user experience and satisfaction. The design of the measurement chamber door also enhances the safety of the instrument. For example, when the door is not closed, the instrument may not be able to start the measurement process, thereby avoiding potential dangers caused by the door not being closed during the measurement process. This design ensures the safety of users when operating the instrument. The cooperation of the indicator light and the measurement chamber door makes the measurement process more optimized and efficient. Users can understand the status of the instrument according to the indication of the indicator light and open or close the measurement chamber door according to their needs. This process design reduces the waiting time and operation complexity in the measurement process, improving the measurement efficiency.

[0037] Optionally, the H. pylori measuring instrument further comprises a printer and a switching power supply, wherein:

[0038] The printer is used to print the measurement results according to the user's instructions;

[0039] The switching power supply is used to convert alternating current into direct current to power all electronic components in the instrument.

[0040] The printer can print the measurement results immediately according to the user's instructions, which provides great convenience for the user. The user does not need to manually record or wait for other devices to transmit data, but can directly obtain the paper version of the measurement results, which is convenient for subsequent analysis, archiving or reporting. By directly printing the measurement results through the printer, errors that may occur during data transmission or recording can be reduced. This way ensures the accuracy and integrity of the data, providing a reliable basis for medical diagnosis or scientific analysis. The addition of the printer makes the Helicobacter pylori measurement instrument more perfect. It not only can make accurate measurements, but also can present the measurement results in paper form to the user, meeting the user's diverse needs. The switching power supply can convert alternating current into direct current to provide stable and reliable power supply for all electronic components in the instrument. This ensures the normal operation of the instrument during measurement, avoiding measurement errors or equipment failures caused by unstable power supply. The switching power supply usually has a wide input voltage range and multiple output voltage options, which makes it able to adapt to different countries and regions' power standards, improving the compatibility and application range of the device. Stable power supply is crucial to prolong the service life of the device. The switching power supply can provide stable current and voltage, reducing the damage to the device caused by voltage fluctuations or excessive current, thereby prolonging the service life of the Helicobacter pylori measurement instrument.

[0041] Optionally, the Helicobacter pylori measurement instrument further comprises a wireless communication module connected with the mainboard, for receiving the third instruction of the user through wireless transmission and transmitting the third instruction to the mainboard.

[0042] The wireless communication module allows the user to send instructions (third instructions) to the measurement instrument wirelessly, which enables the user to control the measurement instrument remotely from a location away from the measurement instrument. For example, the user can send instructions through a smartphone, tablet computer or other device in the office or at home to start or stop the measurement process, adjust the measurement parameters, etc. This remote control function provides great convenience for the user, especially in situations where multiple measurement instruments need to be remotely monitored or managed. In addition to sending instructions, the wireless communication module can also be used to transmit measurement results or data in real time. Once the measurement is complete, the measurement instrument can send the results to the user's mobile device, computer or cloud server through the wireless communication module. In this way, the user can view the measurement results anytime and anywhere, perform data analysis or share with others. This is particularly important for measurement scenarios that require quick response or remote medical consultation. The addition of the wireless communication module makes the measurement instrument more flexible and efficient. The user no longer needs to go to the location of the measurement instrument to operate or view the results, but can control remotely and transmit data wirelessly. This greatly improves the efficiency and flexibility of measurement, especially in scenarios that require frequent measurements.

[0043] To sum up, the one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0044] 1. The display screen not only serves as an information display window, but also as an interface for user input instructions. Users can directly input first instructions (such as starting measurement, selecting measurement mode, etc.) through the display screen without the need for additional physical buttons or external devices, greatly simplifying the operation process and improving the convenience of user interaction.

[0045] 2. The mainboard, as the core processing unit of the system, is responsible for receiving and processing first instructions from the display screen, generating corresponding second instructions and sending them to the detector. At the same time, the mainboard is also responsible for receiving feedback from the detector Ray energy spectrum information, data processing (such as signal amplification, filtering, sampling, analysis, etc.), generating display information and sending it to the display screen for display. This design makes the data processing and display process efficient and accurate, ensuring the real-time and reliability of the measurement results.

[0046] 3. The detector acquires the Ray energy spectrum information in the gas collection card to be measured according to the second instructions transmitted by the mainboard. Since the detector can accurately capture and measure the Ray energy spectrum, it can accurately reflect the content or activity of Helicobacter pylori in the sample to be measured. This high-precision measurement method is of great significance for early detection and diagnosis of diseases.

[0047] 4. Through the close communication connection between the mainboard, display screen and detector, the system can operate stably, reducing measurement errors caused by poor communication or data loss between components. At the same time, the cooperative work between each component also improves the overall reliability of the system, ensuring the accuracy and repeatability of the measurement results.

[0048] 5. The design of the measurement instrument has certain scalability and upgradeability. For example, the firmware or software of the mainboard can be upgraded to support more measurement modes or functions; higher-performance detectors can be replaced to improve measurement accuracy and speed; additional communication interfaces can be added to realize interconnection and intercommunication with other devices. This design makes the measurement instrument adaptable to future technological development and changes in user needs. BRIEF DESCRIPTION OF DRAWINGS

[0056] The technical solutions provided by the present application can be applied to the scene where the construction site equipment instrument is in a no-signal state.

[0057] The present application provides a Helicobacter pylori measuring instrument, referring to Figure 1 , Figure 1 is a schematic diagram of the Helicobacter pylori measuring instrument provided by the embodiments of the present application. As shown in Figure 1 , the Helicobacter pylori measuring instrument comprises a display screen 1, a mainboard 2 and a detector 3, the mainboard 2 is in communication connection with the detector 3 and the display screen 1 respectively, wherein:

[0058] The display screen 1 is used for receiving a first instruction input by a user and transmitting the first instruction to the mainboard 2, and receiving display information fed back by the mainboard 2 and displaying the display information;

[0059] The mainboard 2 is configured to receive and process the first instruction transmitted by the display screen 1 to generate a second instruction, transmit the second instruction to the detector 3, receive and process the ray spectrum information fed back by the detector 3 to generate display information, and send the display information to the display screen 1.

[0060] The detector 3 is configured to receive the second instruction transmitted by the mainboard 2, and acquire ray spectrum information in the to-be-measured gas collection card according to the second instruction, and transmit the ray spectrum information to the mainboard 2.

[0061] The display screen 1 is an interface for a user to interact with the measuring instrument. The user can input instructions (referred to as first instructions) through the display screen 1, such as selecting a measurement mode, viewing historical data, and the like. The display screen 1 receives display information transmitted by the mainboard 2 and displays the display information. The display information can include measurement results, device states, error prompts, and the like. The mainboard 2 is the “brain” of the measuring instrument, and is responsible for processing various data and instructions. The mainboard 2 receives the first instructions transmitted by the display screen 1, and generates second instructions according to the first instructions. The second instructions can be instructions for controlling the detector 3 to start measurement, adjusting measurement parameters, and the like. The mainboard 2 also receives ray spectrum information fed back by the detector 3. The ray spectrum information is obtained by the detector 3 by measuring rays generated by the decay of radioactive isotopes in the to-be-measured gas collection card. The mainboard 2 processes the ray spectrum information to generate display information. The mainboard 2 transmits the processed display information back to the display screen 1 for the user to view. The detector 3 is a core component of the measuring instrument, and is responsible for acquiring ray spectrum information in the to-be-measured gas collection card. The detector 3 receives the second instructions transmitted by the mainboard 2, which instruct the detector 3 to start measurement, adjust measurement sensitivity, and the like. According to the received instructions, the detector 3 measures rays generated by the decay of radioactive isotopes in the to-be-measured gas collection card, and acquires ray spectrum information. The detector 3 transmits the acquired ray spectrum information to the mainboard 2 for further processing by the mainboard 2.

[0062] Optionally, the detector 3 includes a plastic scintillator 31 and a photomultiplier tube 32, wherein:

[0063] The plastic scintillator 31 is configured to acquire rays released by the decay of preset elements in the to-be-measured gas collection card to generate a fluorescent signal.

[0064] The photomultiplier tube 32 is coupled with the plastic scintillator 31 through optical silicon grease, and is configured to perform photoelectric conversion and amplification on the fluorescent signal to generate a pulse signal.

[0065] Figure 2 is a schematic diagram of the detector 3 provided by an embodiment of the present application, as Figure 2As shown, the plastic scintillator 31 is a material capable of absorbing rays and converting them into visible light (fluorescent signal). When the preset elements in the gas collection card to be measured decay and release rays, these rays will hit the plastic scintillator 31. After the plastic scintillator 31 absorbs these rays, it will quickly emit visible light (fluorescent signal). The intensity of the fluorescence is proportional to the energy and number of rays, so the fluorescent signal can be used to represent the decay of the preset elements in the gas collection card to be measured. In the H. pylori measurement instrument, the plastic scintillator 31 is used to capture the rays released by the decay of radioactive isotopes in the gas collection card to be measured and convert them into fluorescent signals that are easy to detect. The photomultiplier tube 32 is a high-sensitivity photoelectric conversion device that can convert weak light signals into electrical signals (pulse signals) and amplify them. The photomultiplier tube 32 contains multiple dynodes inside. When the fluorescent signal enters the photomultiplier tube 32 through optical silicone coupling, it is first converted into photoelectrons by the photocathode. These photoelectrons are accelerated by the electric field and hit the dynodes, producing more secondary electrons. These secondary electrons continue to be accelerated and hit, forming an electron multiplication effect, thereby amplifying the light signal. Finally, the amplified electrical signal (pulse signal) is output. The photomultiplier tube 32 is coupled with the plastic scintillator 31 through optical silicone. Optical silicone has good light transmission and adhesion, which can ensure that the fluorescent signal is efficiently transmitted from the plastic scintillator 31 to the photomultiplier tube 32. In the H. pylori measurement instrument, the photomultiplier tube 32 is used to receive the fluorescent signal generated by the plastic scintillator 31 and convert it into an amplified electrical signal (pulse signal). These pulse signals are then received and processed by the mainboard 2 to generate display information.

[0066] Figure 3 is the principle schematic diagram of the detector 3 provided by the embodiment of the present application, as Figure 3As shown, the plastic scintillator 31 can efficiently capture the rays released after the decay of the preset elements (such as radioisotopes) in the gas collection card to be measured. These rays interact with the plastic scintillator 31 and generate fluorescent signals. Due to the good ray absorption and fluorescence conversion capability of the plastic scintillator 31, the detector 3 can achieve sensitive detection of weak rays. The photomultiplier tube 32 is tightly coupled with the plastic scintillator 31 through optical silicon grease, ensuring effective transmission of fluorescent signals. The photomultiplier tube 32 can convert the received fluorescent signals into electrical signals and amplify them through multiple stages of multiplication effect to generate pulse signals. This process of photoelectric conversion and amplification improves the strength and signal-to-noise ratio of the signals, enabling the detector 3 to more accurately identify and analyze the ray energy spectrum information. Due to the combined use of the plastic scintillator 31 and the photomultiplier tube 32, the detector 3 can accurately measure the decay of the preset elements in the gas collection card to be measured. Through analysis and processing of the pulse signals, the ray energy spectrum characteristics related to H. pylori can be extracted, enabling accurate detection and quantitative measurement of H. pylori. The plastic scintillator 31 and the photomultiplier tube 32, as core components of the detector 3, have good stability and reliability. They can maintain stable performance in harsh environmental conditions (such as high temperature, high humidity, strong magnetic field, etc.), ensuring the accuracy and repeatability of measurement results. The plastic scintillator 31 and the photomultiplier tube 32 are small in size and light in weight, easy to integrate into the measuring instrument. At the same time, they also have high reliability and durability, reducing maintenance costs and frequency. This makes the measuring instrument more compact, portable and easy to operate.

[0067] Optionally, the main board 2 is further used for:

[0068] receiving the pulse signal after the high-voltage direct-current capacitor is isolated from the high voltage, and processing the pulse signal to obtain the ray energy spectrum information of the gas collection card to be measured.

[0069] In the detector 3, the pulse signal output by the photomultiplier tube 32 is often accompanied by a high voltage. In order to protect the electronic components on the main board 2 from high voltage damage, while ensuring the integrity of the pulse signal, a high-voltage DC isolation capacitor needs to be added between the detector 3 and the main board 2. The high-voltage DC isolation capacitor can isolate the DC high voltage, but allows the pulse signal to pass through, thereby achieving safe transmission of the pulse signal. After receiving the pulse signal isolated by the high-voltage DC isolation capacitor, the main board 2 will perform a series of processing on it. These processing includes signal amplification, filtering, sampling, digitization and other steps to extract information related to the energy spectrum of the rays. The amplification circuit on the main board 2 will amplify the pulse signal to improve the strength of the signal for subsequent processing. Through the filter circuit, the noise and interference components in the pulse signal can be removed, improving the signal-to-noise ratio of the signal. The analog pulse signal after amplification and filtering is converted to a digital signal for computer processing and analysis. The processor on the main board 2 will perform energy spectrum analysis on the digitized pulse signal to extract the ray energy spectrum information related to the decay of the preset elements in the gas collection card being measured.

[0070] The use of high-voltage DC isolation capacitor effectively isolates the direct electrical connection between the high voltage generated in the detector 3 and the main board 2. This not only protects the main board 2 from high voltage damage, but also prevents the influence of electromagnetic interference caused by high voltage on the pulse signal, ensuring the integrity and accuracy of the signal. The main board 2 has the ability to process the pulse signal with high precision. It can filter, amplify, shape and sample the received pulse signal to extract characteristic information related to the energy spectrum of the rays. This processing capability is the key to ensuring that the measuring instrument can accurately measure the energy spectrum information of the rays. By processing the pulse signal, the main board 2 can extract the ray energy spectrum information generated by the decay of the preset elements in the gas collection card being measured. These information includes the energy distribution and intensity of the rays, which are important for analyzing and identifying target substances such as Helicobacter pylori. The main board 2, as one of the core components of the measuring instrument, its stability and reliability are crucial to the performance of the entire system. By receiving and processing the pulse signal isolated by high voltage, the main board 2 can ensure the accuracy and repeatability of the measurement results, and improve the overall stability and reliability of the system.

[0071] Optionally, the detector 3 further comprises a metal shell 33, a high-voltage voltage dividing plate and a high-voltage shield coaxial cable, wherein:

[0072] The metal shell 33 is located outside the plastic scintillator 31 and the photomultiplier tube 32 to protect the plastic scintillator 31 and the photomultiplier tube 32;

[0073] The high-voltage voltage dividing plate is used to provide the required high voltage for the photomultiplier tube 32;

[0074] The high-voltage shielded coaxial cable is used to connect the main board 2 and the detector 3. It is used to transmit high voltage and the pulse signal, and ensures the isolation of the high voltage and the pulse signal from other devices and space electromagnetic interference.

[0075] The metal shell 33 is located outside the plastic scintillator 31 and the photomultiplier tube 32. The main function of the metal shell 33 is to protect the internal plastic scintillator 31 and photomultiplier tube 32 from external environmental damage. It can prevent the influence of external factors such as physical impact, dust, moisture, etc. on the internal components of the detector 3, ensuring the stability and reliability of the detector 3. The high-voltage dividing board is an important component in the detector 3, which is responsible for providing the required high voltage for the photomultiplier tube 32. The photomultiplier tube 32 needs a certain voltage to accelerate photoelectrons when working, so as to produce a multiplication effect and convert weak light signals into stronger electrical signals. The high-voltage dividing board ensures the normal work of the photomultiplier tube 32 by precisely controlling the distribution of voltage. The high-voltage shielded coaxial cable is used to connect the main board 2 and the detector 3. The cable contains high-voltage transmission lines inside, which are used to transmit the high voltage generated by the high-voltage dividing board to the photomultiplier tube 32. At the same time, the cable is also responsible for transmitting the pulse signal generated by the plastic scintillator 31 and the photomultiplier tube 32. These signals contain the information of the radiation spectrum in the gas collection card to be measured. The design of the high-voltage shielded coaxial cable ensures the effective isolation of high voltage and the pulse signal from other devices and space electromagnetic interference. This can prevent high-voltage discharge and ensure the accuracy and integrity of the signal.

[0076] The metal shell 33 is located outside the plastic scintillator 31 and photomultiplier tube 32, which plays an effective protection role. It can prevent external physical impact, vibration and environmental pollution from damaging the internal sensitive components, ensuring the long-term stable operation of the detector 3. The metal shell 33 also has certain electromagnetic shielding function, which can reduce the interference of external electromagnetic field on the internal circuit of the detector 3, improve the stability and accuracy of the signal. The high-voltage dividing board is a key component necessary for the normal operation of the photomultiplier tube 32. It can provide stable high-voltage output to ensure that the photomultiplier tube 32 works at the appropriate voltage, thereby realizing efficient signal amplification and conversion. The high-voltage dividing board also has the function of adjusting the voltage range, which can adjust the output voltage according to different application requirements to adapt to different types or specifications of photomultiplier tubes 32. The high-voltage shielded coaxial cable serves as a bridge connecting the main board 2 and the detector 3, which can transmit high-voltage and pulse signals at the same time. This design not only simplifies the wiring of the system, but also improves the transmission efficiency of the signal. The high-voltage shielded coaxial cable adopts a special shielding structure, which can effectively isolate the interference of high-voltage discharge and electromagnetic radiation. This not only protects the main board 2 from high-voltage damage, but also ensures the integrity and accuracy of the pulse signal, thereby improving the accuracy of the measurement results. By ensuring the isolation between high-voltage and pulse signals, the high-voltage shielded coaxial cable also enhances the stability of the entire system. It reduces the system fluctuations and errors caused by signal interference, improving the reliability and repeatability of the measuring instrument.

[0077] Optionally, the detector 3 also includes a measurement chamber 34 and a sample in-place sensor 35, wherein:

[0078] The measurement chamber 34 is used to place the to-be-measured gas collection card;

[0079] The sample in-place sensor 35 is used to monitor whether the to-be-measured gas collection card is placed in the measurement chamber 34 and feed back the monitoring result to the main board 2.

[0080] The measurement chamber 34 is a key component in the detector 3, which is specially designed to place the to-be-measured gas collection card. The decay of 14C in the to-be-measured gas collection card will release β rays. The measurement chamber 34 provides a closed and stable environment, which helps to reduce external interference and improve measurement accuracy. The sample in-place sensor 35 is a detection device used to monitor whether the to-be-measured gas collection card is placed in the measurement chamber 34. It usually detects the presence of the gas collection card through physical contact or optical sensing, etc. When the gas collection card is detected to be placed in the measurement chamber 34, the sensor sends a signal to the main board 2, indicating that the measurement can begin.

[0081] The introduction of the sample in-situ sensor 35 greatly improves the automation of the measurement process. It ensures that the detector 3 will only start working after the gas collection card is correctly placed, thus avoiding measurement errors caused by improper operation or failure to place the gas collection card. In addition, the sensor can monitor the status of the gas collection card in real time. If the gas collection card is accidentally moved or removed during the measurement process, the sensor will immediately send a signal to the main board 2 to stop the measurement process and protect the detector 3 and the gas collection card from damage.

[0082] Optionally, the motherboard 2 is also used for:

[0083] Logical judgment is made on the monitoring results of the sample in-situ sensor 35. If the gas collection card to be tested is not detected, the measurement process is paused and a prompt message is sent to the display screen 1.

[0084] As the core control component of detector 3, motherboard 2 is responsible not only for processing pulse signals from detector 3 but also for monitoring and managing the status of various system components. One crucial function of motherboard 2 is to perform logical judgments on the monitoring results from sample in-situ sensor 35. Motherboard 2 receives monitoring results from sample in-situ sensor 35 via internal circuitry or a communication interface. This monitoring result is typically an electrical signal indicating whether a gas collection card to be tested is placed in measurement chamber 34. Motherboard 2 performs logical judgments on the received monitoring results. If the monitoring result indicates that no gas collection card to be tested is placed in measurement chamber 34 (i.e., the sensor does not detect the presence of the gas collection card), motherboard 2 will proceed to the next step. When motherboard 2 determines that no gas collection card to be tested is present in measurement chamber 34, it immediately pauses the measurement process. This includes stopping the transmission of measurement commands to detector 3 and shutting off the high-voltage power supply to ensure the system is in a safe state. Simultaneously, motherboard 2 will also send a prompt message to the operator via display screen 1. This prompt message is usually a simple text or icon informing the operator that no gas collection card is placed in measurement chamber 34 and that the gas collection card needs to be manually inserted before measurement can continue.

[0085] Optionally, the Helicobacter pylori measuring instrument also includes an instrument housing 4, which is used to support and fix the detector 3, the motherboard 2 and the display screen 1.

[0086] The instrument shell 4 is the external structure of the H. pylori measuring instrument, which is designed to carry and fix the key components of the measuring instrument, including the probe 3, the mainboard 2 and the display screen 1. These components are the basis for the normal operation of the measuring instrument, and the instrument shell 4 provides a stable and safe operating environment. The primary function of the instrument shell 4 is to carry and fix the components of the measuring instrument. Through reasonable structural design and internal support, the shell can ensure that the components such as the probe 3, the mainboard 2 and the display screen 1 remain stable after installation and will not be displaced or damaged due to vibration or external force. The instrument shell 4 also plays a protective and safety role. It can prevent external physical impact, dust, moisture and other harmful substances from entering the interior of the measuring instrument, thereby protecting the internal electronic components and optical devices from damage. In addition, the design of the shell can also consider electromagnetic compatibility (EMC) and electromagnetic interference (EMI) protection to ensure that the measuring instrument can work normally in a complex electromagnetic environment. In addition to the basic carrying and protection functions, the design of the instrument shell 4 can also focus on aesthetics and portability. By adopting a streamlined appearance design and appropriate material selection, the shell can make the measuring instrument look more fashionable and high-end. At the same time, by optimizing the size and weight of the shell, the measuring instrument can be more portable and mobile, meeting the user's needs in different scenarios. Various signs and operation buttons can also be set on the instrument shell 4 to facilitate user operation and identification. For example, the shell can be printed with the model, brand, operation guide and other information of the measuring instrument, as well as power switch, function selection and other buttons, so that users can easily get started and quickly understand the functions and use methods of the measuring instrument.

[0087] Optionally, the H. pylori measuring instrument further comprises an indicator light 5 and a measurement chamber door 6, wherein:

[0088] The indicator light 5 is connected with the mainboard 2, and is used to display the working state of the instrument according to the indication signal of the mainboard 2, the working state including standby, measurement in progress, fault;

[0089] The measurement chamber door 6 is arranged on the instrument shell 4 at the opening of the measurement chamber 34, and is used to ensure that the measurement chamber 34 is in a darkroom state when the measurement chamber door 6 is closed.

[0090] The indicator light 5 is an important part of the H. pylori measurement instrument, which is connected with the mainboard 2, used to display the working state of the instrument. These working states usually include standby, measurement and fault three cases. When the measurement instrument is in standby state, the indicator light 5 will send a specific light signal (such as blue), indicating that the measurement instrument has been powered on but has not started measuring. When the measurement instrument starts measuring, the indicator light 5 will change the light signal (such as changing to green), to remind the operator that the measurement is in progress. If the measurement instrument fails or abnormally during measurement, the indicator light 5 will send a warning signal (such as changing to red), prompting the operator to check and troubleshoot. The design of the indicator light 5 allows the operator to intuitively understand the working state of the measurement instrument, so as to take corresponding operation measures. This greatly improves the ease of use and reliability of the measurement instrument. The measurement chamber door 6 is a key component set on the instrument shell 4, located at the opening of the measurement chamber 34. Its main function is to ensure that the measurement chamber 34 is in a dark room state when the measurement chamber door 6 is closed. After the measurement chamber door 6 is closed, it can effectively isolate external light from entering the measurement chamber 34. This is crucial for the normal operation of the measurement instrument, because the interference of external light may affect the accuracy of the measurement results. By maintaining the dark room state of the measurement chamber 34, it can ensure that the measurement instrument can capture more accurate and stable data during measurement. The measurement chamber door 6 also has a certain safety protection function. It can prevent the operator or external objects from accidentally contacting the sensitive components in the measurement chamber 34 during measurement, thereby protecting the measurement instrument and the operator from injury.

[0091] Optionally, the H. pylori measurement instrument further comprises a printer 7 and a switching power supply 8, wherein:

[0092] The printer 7 is used to print the measurement results according to the user's instructions;

[0093] The switching power supply 8 is used to convert alternating current into direct current to power all electronic components in the instrument.

[0094] Printer 7 is an important additional component of the H. pylori measurement instrument, which allows users to print the measurement results according to instructions. This is particularly useful for situations where the measurement results need to be recorded for subsequent analysis or reporting. Printer 7 usually supports multiple printing formats, including text, tables, and charts, to meet the needs of different users. Users can input printing instructions through the display screen 1 of the measurement instrument or other devices such as external computers, select the measurement results and formats that need to be printed, and then the printer 7 will print these information on paper. The introduction of printer 7 makes users no longer need to manually record measurement results, greatly improving work efficiency and accuracy. At the same time, the printed results are also easier to save and share, facilitating users to communicate and discuss with others. Switching power supply 8 is another key component of the H. pylori measurement instrument, which is responsible for converting alternating current into direct current to power all electronic components in the instrument. Switching power supply 8 uses high-efficiency conversion technology to convert the alternating current power in the home or office into the direct current power required by the measurement instrument. This conversion process not only is stable and reliable, but also can reduce energy waste and heat generation, improving the overall performance of the instrument. Switching power supply 8 also has certain safety protection functions. It can monitor the changes of current and voltage, and automatically cut off the power supply when abnormalities occur, to protect the safety of the measurement instrument and users. In addition, switching power supply 8 usually adopts waterproof, dustproof and other designs to meet the use requirements in different environmental conditions.

[0095] Optionally, the H. pylori measurement instrument further comprises a wireless communication module connected with the mainboard 2, for receiving the third instruction of the user through wireless transmission and transmitting the third instruction to the mainboard 2.

[0096] The wireless communication module is an important part of the H. pylori measurement instrument, which is connected with the mainboard 2 and is responsible for receiving the user's instructions (hereinafter referred to as the third instruction) through wireless transmission and transmitting these instructions to the mainboard 2 for processing. The wireless communication module uses wireless communication technology such as Wi-Fi, Bluetooth or Zigbee to realize wireless connection with the user. This means that the user does not need to connect to the measurement instrument through physical cables, but can send instructions or receive data to the measurement instrument within a certain range (depending on the coverage range of the wireless communication technology). When the user sends instructions to the measurement instrument through a smartphone, tablet computer or other wireless device, the wireless communication module receives these instructions and converts them into a format that the mainboard 2 can understand. Then, it transmits these instructions to the mainboard 2 for further processing or execution. The introduction of the wireless communication module enables users to interact with the measurement instrument in a more flexible and convenient way. For example, users can send instructions from a location away from the measurement instrument, or control multiple measurement instruments to work together. In addition, wireless communication also enables the measurement instrument to be integrated with other smart devices or systems, realizing more intelligent application scenarios.
