Description

Technical Field

[0001] This invention relates to the field of medical device disinfection technology, specifically to an intelligent disinfection control method and device for an otoscope, and a computer device. Background Technology

[0002] As one of the most commonly used examination tools in otolaryngology, the probe of an otoscope comes into direct contact with the patient's external auditory canal and even the tympanic membrane, making it highly susceptible to contamination from earwax, secretions, microorganisms, and even blood. Without effective sterilization, cross-infection can easily occur, potentially leading to hospital-acquired infections (HAIs) and threatening the health of both patients and healthcare workers. The World Health Organization and national disease control centers have clearly mandated strict sterilization or disinfection procedures for reusable endoscopic instruments.

[0003] Traditional methods of disinfecting otoscopes mostly rely on manual wiping or soaking in chemical disinfectants, which are not only inefficient and prone to improper operation but also fail to guarantee thorough disinfection. While some high-end devices incorporate ultraviolet (UV) disinfection, their irradiation parameters are often fixed and cannot be dynamically adjusted. This can lead to over-disinfection damaging optical components or under-disinfection leaving potential infection risks, failing to meet the high requirements of traceability and safety in modern medicine. For example, some devices automatically initiate fixed-duration (e.g., 30 or 60 seconds) UV irradiation after probe insertion, applying the same dosage regardless of whether the probe is clean or heavily contaminated. A few high-end products add UV intensity or temperature sensors for coarse feedback, but these are only used for fault alarms or simple start / stop control and do not collect contamination information.

[0004] To address the aforementioned issues, this invention proposes an intelligent disinfection control method for otoscopes to improve the reliability of the disinfection process and avoid the risk of cross-infection due to human negligence. Summary of the Invention

[0005] In view of the above problems, the present invention provides an intelligent disinfection control method and device for an otoscope, and a computer device.

[0006] According to one aspect of the present invention, a smart disinfection control method for an otoscope is provided, comprising:

[0007] Before the disinfection process is initiated, the sensor array located on the detachable probe base of the otoscope synchronously collects the contamination spectrum data, ultraviolet intensity reference data, disinfection temperature and humidity data, and probe insertion status signal of the endoscopic optical window at the front end of the probe to obtain the initial state vector of disinfection.

[0008] The dynamic contamination index is calculated based on the initial state vector of disinfection, the historical frequency of probe use, and the time interval between adjacent uses.

[0009] Based on the dynamic pollution index and the preset disinfection mapping table, basic disinfection parameters are matched, and the basic disinfection parameters are dynamically calibrated according to the degree of index deviation to generate a personalized disinfection protocol including irradiation mode and dosage.

[0010] During the execution of the personalized disinfection protocol, process protection control is performed based on ultraviolet intensity benchmark data, disinfection temperature and humidity data, and preset thresholds.

[0011] After disinfection, cumulative ultraviolet dose compliance verification and pollution spectral data comparison verification are performed. When the compliance verification and comparison verification are passed, the disinfection completion status and cycle verification code are written to the radio frequency identification chip on the probe carrier, which is used to perform hardware interlocking of the otoscope circuit when the probe is reinstalled.

[0012] In one alternative approach, after the detachable probe of the otoscope is physically connected to the base of the main unit and the power is turned on, the insertion status signal of the probe is detected by a photoelectric sensor installed in the base. When the insertion status signal confirms that the probe is stably located in the disinfection chamber, the synchronous acquisition command of the sensor array is triggered.

[0013] The sensor array includes an ultraviolet-visible spectroscopy sensor located on the top of the disinfection chamber, an ultraviolet radiation reference sensor located on the chamber wall, and a temperature and humidity sensor located inside the chamber.

[0014] In one alternative approach, the dynamic pollution index is calculated using the following formula:

[0022] In one optional approach, the preset disinfection mapping table is a three-layer preset disinfection mapping table;

[0023] The first layer is a mapping table between pollution levels and basic parameters, which is used to discretize the continuous dynamic pollution index into multiple pollution levels and preset a set of basic disinfection parameters for each level. The basic disinfection parameters include the baseline ultraviolet irradiation dose, the baseline irradiation power, the baseline irradiation duration, and the baseline irradiation mode. The irradiation modes include continuous irradiation mode, pulse modulation mode, and staged variable power mode.

[0024] The second layer is a probe type and correction coefficient table, which is used to match the corresponding optical material transmittance correction coefficient, geometric structure attenuation coefficient and thermal sensitivity coefficient based on the probe model identification read from the RFID chip on the probe carrier.

[0025] The third layer is the environmental compensation table, which is used to provide the UV lamp efficiency temperature compensation coefficient and environmental humidity influence coefficient based on the real-time temperature and relative humidity in the disinfection temperature and humidity data.

[0026] In one alternative approach, dynamically calibrating the basic disinfection parameters based on the degree of exponential deviation to generate a personalized disinfection protocol including irradiation mode and dosage further includes:

[0027] Based on the dynamic pollution index threshold range corresponding to the current pollution level obtained from the mapping table between the first-level pollution level and the basic parameters, the index deviation factor is calculated; based on the index deviation factor and the compensation factor generator, the intensity compensation coefficient and the time compensation coefficient are generated.

[0028] The optical material transmittance correction coefficient, geometric structure attenuation coefficient, and thermal sensitivity coefficient of the current probe are read from the second-layer probe type and correction coefficient table. The UV lamp efficiency temperature compensation coefficient and environmental humidity influence coefficient corresponding to the current real-time temperature and relative humidity are obtained from the third-layer environmental compensation table. A probe-environment integrated correction factor matrix is ​​established based on the optical material transmittance correction coefficient, geometric structure attenuation coefficient, thermal sensitivity coefficient, UV lamp efficiency temperature compensation coefficient, and environmental humidity influence coefficient.

[0029] The probe and environment integrated correction factor matrix is ​​dynamically corrected based on the intensity compensation coefficient and the time compensation coefficient, and encapsulated into a structured protocol object including the irradiation mode and dose; wherein, the structured protocol object includes protocol ID, probe identifier, protocol generation timestamp, calibration parameter set and expected cumulative dose target value.

[0030] In one alternative approach, during the disinfection process, a closed-loop dose control loop is constructed using ultraviolet intensity benchmark data and real-time ultraviolet radiation sensor feedback values.

[0031] Specifically, the preset cumulative ultraviolet dose target value is decomposed into target sub-dose for multiple time segments, and the deviation between the actual cumulative dose and the target sub-dose is compared at the end of each time segment; if the deviation exceeds the preset tolerance threshold, the ultraviolet lamp driving current or pulse duty cycle for the next time segment is dynamically adjusted according to the deviation direction and amplitude; the output of the closed-loop dose control loop is the corrected irradiation parameter command.

[0032] In one alternative approach, when the probe is reinstalled into the otoscope host, the host reads the disinfection completion status and cycle check code stored in the radio frequency identification chip via near-field communication and performs hardware interlock verification.

[0033] The process involves verifying whether the cyclic checksum matches the locally generated hash value. If they do not match, the device is prevented from starting and an abnormal disinfection record is displayed. If they match, the time difference between the current system time and the timestamp generated by the protocol is compared to see if it exceeds the preset validity period threshold. If it exceeds the threshold, the device is considered to have failed disinfection and is forced to enter the waiting-for-disinfection state. At the same time, the host writes the current usage event into the chip's usage frequency counter and updates the adjacent usage time interval parameter.

[0034] In an alternative approach, the method further includes:

[0035] While the otoscope main unit is in standby mode, the probe insertion status signal and the rate of change of ambient temperature and humidity are continuously monitored.

[0036] When the probe is detected to have been removed and the expected time interval between uses is less than a preset threshold, the UV lamp preheating circuit is activated in advance and a slightly positive pressure dry airflow is maintained in the chamber. At the same time, based on the pollution level and environmental conditions recorded at the end of the last use, the most likely applicable disinfection protocol template is preloaded into the cache.

[0037] When the probe is reinserted and the insertion status signal is stable, the sensor array is started to acquire data synchronously and the preloaded protocol is used as the initial guess value.

[0038] According to another aspect of the present invention, an intelligent disinfection control device for an otoscope is provided, comprising:

[0039] The initial state sensing module is used to simultaneously collect pollution spectrum data, ultraviolet intensity reference data, disinfection temperature and humidity data, and probe insertion status signal from the endoscopic optical window at the front end of the probe through a sensor array set on the detachable probe base of the otoscope before disinfection is started, so as to obtain the initial state vector of disinfection.

[0040] The dynamic contamination assessment module is used to calculate the dynamic contamination index based on the initial disinfection state vector, the probe's historical usage frequency, and the time interval between adjacent uses.

[0041] The personalized protocol generation module is used to match basic disinfection parameters according to the dynamic pollution index and the preset disinfection mapping table, dynamically calibrate the basic disinfection parameters according to the degree of index deviation, and generate a personalized disinfection protocol including irradiation mode and dosage.

[0042] The process safety monitoring module is used to perform process protection control based on ultraviolet intensity reference data, disinfection temperature and humidity data and preset thresholds during the execution of the personalized disinfection protocol.

[0043] The disinfection verification and interlocking writing module is used to verify the cumulative ultraviolet dose compliance and the pollution spectrum data comparison after disinfection. After the compliance verification and comparison verification are passed, the disinfection completion status and cycle verification code are written to the radio frequency identification chip on the probe carrier, which is used to perform hardware interlocking of the otoscope circuit when the probe is reinstalled.

[0044] According to another aspect of the present invention, a computer device is provided, comprising: a processor, a memory, a communication interface, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other through the communication bus;

[0045] The memory is used to store at least one executable instruction, which causes the processor to perform the operation corresponding to the intelligent disinfection control method for the otoscope described above.

[0046] According to the solution provided by this invention, before disinfection is initiated, a sensor array installed on the detachable probe base of the otoscope synchronously collects contamination spectrum data, ultraviolet intensity reference data, disinfection temperature and humidity data, and probe insertion status signals from the endoscopic optical window at the probe tip to obtain an initial disinfection state vector. A dynamic contamination index is calculated based on the initial disinfection state vector, the probe's historical usage frequency, and adjacent usage time intervals. Basic disinfection parameters are matched according to the dynamic contamination index and a preset disinfection mapping table. The basic disinfection parameters are dynamically calibrated based on the degree of index deviation to generate a personalized disinfection protocol including irradiation mode and dosage. During the execution of the personalized disinfection protocol, process protection control is performed based on ultraviolet intensity reference data, disinfection temperature and humidity data, and preset thresholds. After disinfection, cumulative ultraviolet dose compliance verification and contamination spectrum data comparison verification are performed. When the compliance verification and comparison verification pass, a disinfection completion status and a cyclic verification code are written to the RFID chip on the probe, which is used for hardware interlocking of the otoscope circuitry when the probe is reinstalled. This invention significantly improves the reliability of the disinfection process and avoids the risk of cross-infection due to human negligence. Specifically, the personalized disinfection protocol intelligently matches the irradiation dose, power, duration, and mode (continuous / pulse / phased) based on the severity of contamination, probe material, and environmental conditions. This avoids the infection risk caused by insufficient disinfection and the equipment aging and energy waste caused by excessive disinfection. By comparing the deviation between the actual cumulative dose and the target value, the driving current or pulse duty cycle of the UV lamp is dynamically adjusted. Only after both verifications pass is the disinfection completion status and cycle verification code written to the probe's RFID chip, ensuring verifiable disinfection quality for each disinfection. When the probe is reinstalled into the host, the host must read the disinfection status and verification code from its chip via near-field communication and compare it with the locally calculated value, avoiding the risk of cross-infection due to human negligence.

The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings.

[0052] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0053] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0054] Figure 1 A flowchart illustrating an intelligent disinfection control method for an otoscope according to an embodiment of the present invention is shown. Specifically, as... Figure 1 As shown, it includes the following steps:

[0055] Step S101: Before disinfection is started, the sensor array set on the detachable probe base of the otoscope synchronously collects the pollution spectrum data, ultraviolet intensity reference data, disinfection temperature and humidity data, and probe insertion status signal of the endoscopic optical window at the front end of the probe to obtain the initial state vector of disinfection.

[0056] In this embodiment, as shown in Table 1, the absorbance / reflectance of contaminants such as biofilms, earwax, and secretions on the surface of the optical window is directly detected at characteristic wavelengths using an ultraviolet-visible spectral sensor, converting "dirtiness" into calculable spectral data. The acquisition and disinfection process is triggered only after the photoelectric sensor confirms that the probe is fully inserted into the disinfection chamber, avoiding ultraviolet leakage, uneven irradiation, or equipment malfunction caused by the probe not being properly positioned.

[0057] Table 1

[0058]

[0059] Note: "—" indicates that because the insertion status is 0, the remaining data is not collected or is invalid.

[0060] In one alternative approach, after the detachable probe of the otoscope is physically connected to the base of the main unit and the power is turned on, the insertion status signal of the probe is detected by a photoelectric sensor installed in the base. When the insertion status signal confirms that the probe is stably located in the disinfection chamber, the synchronous acquisition command of the sensor array is triggered.

[0061] The sensor array includes an ultraviolet-visible spectroscopy sensor located on the top of the disinfection chamber, an ultraviolet radiation reference sensor located on the chamber wall, and a temperature and humidity sensor located inside the chamber.

[0062] In this embodiment, for example, after performing an ear examination on a patient using an otoscope in a hospital, the doctor removes the detachable probe from the patient's ear and inserts it into the sterilization chamber of the main unit base for sterilization. After the probe is inserted into the base, the photoelectric sensor immediately detects the probe entering the chamber and continuously monitors its positional stability. Once the probe has been stably positioned within the chamber (e.g., without shaking and with good contact) for 0.5 seconds, the control unit determines that the probe is stably in place and automatically triggers the synchronous acquisition command of the sensor array. The ultraviolet-visible spectroscopy sensor illuminates the probe's optical window from the top of the chamber to collect reflectance spectral data to analyze the degree of biofilm or particulate contamination on the window surface; the ultraviolet radiation reference sensor measures the reference intensity of the current ultraviolet light source from the chamber wall; and the temperature and humidity sensor acquires the ambient temperature and humidity within the chamber in real time.

[0063] Step S102: Calculate the dynamic contamination index based on the initial disinfection state vector, the probe's historical usage frequency, and the time interval between adjacent uses.

[0064] In this embodiment, a dynamic contamination index is constructed by combining the initial disinfection state vector with the probe's historical usage frequency and the time interval between adjacent uses. This ensures that the disinfection intensity closely matches the actual contamination risk, avoiding over-disinfection or under-disinfection. Shorter time intervals between adjacent uses increase the likelihood of residual contaminant accumulation; conversely, prolonged inactivity may lead to natural degradation or drying and solidification of contaminants. Modeling the nonlinear evolution of contaminants over time using time functions (such as complementary error functions) makes the contamination assessment more closely resemble real clinical scenarios. The dynamic contamination index serves as the basis for generating disinfection protocols, enabling the same device to automatically adapt to optimal disinfection parameters under different usage scenarios (such as peak outpatient hours or single examinations). Especially in high-frequency medical environments, historical frequency weighting can identify high-risk probes (e.g., those used continuously for multiple patients), triggering enhanced disinfection procedures and effectively blocking the pathogen transmission chain.

[0065] In one alternative approach, the dynamic pollution index is calculated using the following formula:

[0066]

[0067] in:

[0068]

[0069]

[0070]

[0071]

[0072] in, These are the absorbance / reflectance values ​​measured at the characteristic wavelength set; Including biofilms and particles; This represents the background noise threshold for the corresponding wavelength.

[0073] In this embodiment, for example, probe A is inserted into the sterilization seat after one use.

[0074] Scenario 1: After a routine outpatient visit, the environment is in good condition. Spectral data shows moderate organic residue (SPI=0.6); the last disinfection was 2 hours ago (t=120 minutes); the frequency of disinfection is moderate. =1.2); Current chamber temperature 22°C, humidity 40% ( =1.1); Historical records show that this probe rarely experiences high-risk events ( (Approaching the lower limit of 0.1), the reduction in the total index through the ⊖ operator is minimal. The DPI is 0.7, classifying it as moderate pollution.

[0075] Scenario 2: After examination of significant bleeding in the emergency room, the environment is humid. Spectral data is strong (SPI=1.5); continuous use, with only a 5-minute interval (t=5). =2.0); Chamber temperature 28°C, humidity 80% ( =2.5); similar blood contamination incidents have been recorded in the history of the virus. )high, =0.8). In the ⊖ operation, a very small subtrahend means a weak reduction in the total exponent, indicating that the adverse environment has failed to effectively offset the high risk. =0.8 directly increases the risk through the ⊕ operator. The DPI spikes to 1.9, indicating severe contamination. This demonstrates that the above formula not only responds to the absolute spectral contamination signal (SPI is higher in scenario two), but also... , , Factors such as continuous use, short intervals, harsh environments, and poor historical records amplify the extreme risks compounded by these factors. A favorable environment (Scenario 1) is considered a mitigating factor, but its impact is limited. This allows the final disinfection decisions (such as irradiation dose and duration) to accurately match the actual risks.

[0076] Step S103: Match basic disinfection parameters according to the dynamic pollution index and the preset disinfection mapping table, dynamically calibrate the basic disinfection parameters according to the degree of index deviation, and generate a personalized disinfection protocol including irradiation mode and dosage.

[0077] In this embodiment, basic parameters are initially selected through a mapping table, and then fine-tuned by combining the degree of exponential deviation. This ensures that the UV irradiation mode (such as continuous, pulsed, or segmented variable power) and dose are strictly matched to the actual contamination risk. Even within the same contamination level, the disinfection intensity and time can be fine-tuned based on the specific deviation of DPI from the level threshold (such as whether it is close to the upper or lower limit). This ensures that the deployment of disinfection resources (such as UV dose) is precisely matched with the contamination risk, guaranteeing effective sterilization while minimizing over-disinfection. The generated protocol makes each disinfection process traceable, enhancing the traceability of medical quality management.

[0078] In one optional approach, the preset disinfection mapping table is a three-layer preset disinfection mapping table;

[0079] The first layer is a mapping table between pollution levels and basic parameters, which is used to discretize the continuous dynamic pollution index into multiple pollution levels and preset a set of basic disinfection parameters for each level. The basic disinfection parameters include the baseline ultraviolet irradiation dose, the baseline irradiation power, the baseline irradiation duration, and the baseline irradiation mode. The irradiation modes include continuous irradiation mode, pulse modulation mode, and staged variable power mode.

[0080] The second layer is a probe type and correction coefficient table, which is used to match the corresponding optical material transmittance correction coefficient, geometric structure attenuation coefficient and thermal sensitivity coefficient based on the probe model identification read from the RFID chip on the probe carrier.

[0081] The third layer is the environmental compensation table, which is used to provide the UV lamp efficiency temperature compensation coefficient and environmental humidity influence coefficient based on the real-time temperature and relative humidity in the disinfection temperature and humidity data.

[0082] In this embodiment, for example, after using an otoscope probe, the DPI is 1.1 (belonging to "moderate contamination"), and the current temperature of the disinfection chamber is... The humidity is 65%, and the probe model is Type-B. The first layer query shows "moderate pollution" level, yielding the following basic parameters: baseline dose = Reference power = The baseline duration is 100 seconds, and the mode is "continuous irradiation". The second layer query shows the correction factors for the "Type-B" probe: transmittance coefficient = 0.92, geometric attenuation coefficient = 1.05, and thermal sensitivity coefficient = 0.9. The third layer query shows the environmental compensation. The corresponding temperature compensation coefficient is 1.15 (power needs to be increased at low temperatures), and the humidity influence coefficient for 65% humidity is 1.03.

[0083] In one alternative approach, dynamically calibrating the basic disinfection parameters based on the degree of exponential deviation to generate a personalized disinfection protocol including irradiation mode and dosage further includes:

[0084] Based on the dynamic pollution index threshold range corresponding to the current pollution level obtained from the mapping table between the first-level pollution level and the basic parameters, the index deviation factor is calculated; based on the index deviation factor and the compensation factor generator, the intensity compensation coefficient and the time compensation coefficient are generated.

[0085] The optical material transmittance correction coefficient, geometric structure attenuation coefficient, and thermal sensitivity coefficient of the current probe are read from the second-layer probe type and correction coefficient table. The UV lamp efficiency temperature compensation coefficient and environmental humidity influence coefficient corresponding to the current real-time temperature and relative humidity are obtained from the third-layer environmental compensation table. A probe-environment integrated correction factor matrix is ​​established based on the optical material transmittance correction coefficient, geometric structure attenuation coefficient, thermal sensitivity coefficient, UV lamp efficiency temperature compensation coefficient, and environmental humidity influence coefficient.

[0086] The probe and environment integrated correction factor matrix is ​​dynamically corrected based on the intensity compensation coefficient and the time compensation coefficient, and encapsulated into a structured protocol object including the irradiation mode and dose; wherein, the structured protocol object includes protocol ID, probe identifier, protocol generation timestamp, calibration parameter set and expected cumulative dose target value.

[0087] In this embodiment, the calibration process not only adjusts the dosage and duration, but also dynamically selects the optimal irradiation mode (e.g., continuous low power for mild contamination, pulsed high-energy impact for severe biofilm), ensuring sterilization effectiveness while reducing thermal / optical damage to optical windows or internal components. Personalized disinfection protocols are shown in Table 2.

[0088] Table 2

[0089]

[0090] Step S104: During the execution of the personalized disinfection protocol, process protection control is performed based on ultraviolet intensity reference data, disinfection temperature and humidity data, and preset thresholds.

[0091] In this embodiment, the UV lamp may experience abnormal output (such as overheating, sudden power surge / dip) under abnormal temperature and humidity or aging conditions. By comparing the UV intensity baseline data (from the cavity wall sensor) with the temperature and humidity data in real time to see if they exceed the safety threshold, the disinfection process can be immediately paused or adjusted to avoid secondary risks such as optical window deformation or melting due to high temperature and excessive ozone generation in the disinfection chamber. If the ambient humidity is too high (e.g., RH > 80%), UVC is strongly absorbed by water vapor, and even if the lamp is working normally, the actual dose reaching the contaminated surface may be severely insufficient. Process protection control is not only used for safe shutdown but can also trigger compensation mechanisms (such as extending irradiation time or increasing power) to ensure effective sterilization. For example, insufficient output due to UV lamp aging may require personalized protocols. It is expected to complete in 60 seconds; during execution, the ultraviolet sensor continuously reads only... (below the benchmark) Even if the full duration is not met, an alarm for insufficient lamp efficiency is triggered, disinfection is paused, and a prompt to replace the UV lamp is made; at the same time, the failure record is written to the probe chip to prevent the unsterilized probe from being misused.

[0092] In one alternative approach, during the disinfection process, a closed-loop dose control loop is constructed using ultraviolet intensity benchmark data and real-time ultraviolet radiation sensor feedback values.

[0093] Specifically, the preset cumulative ultraviolet dose target value is decomposed into target sub-dose for multiple time segments, and the deviation between the actual cumulative dose and the target sub-dose is compared at the end of each time segment; if the deviation exceeds the preset tolerance threshold, the ultraviolet lamp driving current or pulse duty cycle for the next time segment is dynamically adjusted according to the deviation direction and amplitude; the output of the closed-loop dose control loop is the corrected irradiation parameter command.

[0094] In this embodiment, the output of the ultraviolet lamp is affected by factors such as aging, temperature, and voltage fluctuations. Open-loop control can easily lead to "nominal dose meeting the target, but actual dose being insufficient." Through real-time feedback and dynamic adjustment, the actual cumulative dose is always kept close to the target value (e.g., ...). This ensures the effectiveness of disinfection from the ground up. If the measured dose is lower than expected (e.g., lamp decay), the drive current or duty cycle is automatically increased; if it is higher than expected (e.g., increased reflection), the power is reduced to avoid excessive irradiation that could damage the probe's optical components.

[0095] Step S105: After disinfection is completed, the cumulative ultraviolet dose meets the standard and the pollution spectrum data is compared and verified. When the standard verification and comparison verification are passed, the disinfection completion status and cycle verification code are written to the radio frequency identification chip on the probe carrier, which is used to perform hardware interlocking of the otoscope circuit when the probe is reinstalled.

[0096] In this embodiment, the cumulative ultraviolet dose meets the standard to verify and confirm the physical sterilization energy (such as...). The disinfection process has been completed. By observing changes in the reflection / absorption spectra of the optical window before and after disinfection, it's determined whether contaminants (such as cerumen and biofilm) have been removed, avoiding issues like irradiation without cleaning or ineffective dosage. When the probe is reinstalled, the main unit reads the chip status via near-field communication (NFC / RFID). If there is no valid disinfection record, the hardware is powered off and interlocked, preventing the device from starting. If the verification code does not match, it's determined that the record has been tampered with or damaged, forcing the device into a pending disinfection state, physically blocking the risk of cross-infection. For example, cumulative dosage... (Target 40) Met; the spectrum shows 280nm (protein characteristic peak), and the absorbance drops from 0.35 to 0.08, indicating that the contaminants have been removed; the status and verification code are written to the RFID; the host reads and verifies the data the next time it is used, and the computer starts up normally.

[0097] In one alternative approach, when the probe is reinstalled into the otoscope host, the host reads the disinfection completion status and cycle check code stored in the radio frequency identification chip via near-field communication and performs hardware interlock verification.

[0098] The process involves verifying whether the cyclic checksum matches the locally generated hash value. If they do not match, the device is prevented from starting and an abnormal disinfection record is displayed. If they match, the time difference between the current system time and the timestamp generated by the protocol is compared to see if it exceeds the preset validity period threshold. If it exceeds the threshold, the device is considered to have failed disinfection and is forced to enter the waiting-for-disinfection state. At the same time, the host writes the current usage event into the chip's usage frequency counter and updates the adjacent usage time interval parameter.

[0099] In this embodiment, the protocol generates a timestamp and compares it with a preset validity period threshold. This makes the disinfection status no longer permanently valid, enabling the identification of probes that have been effectively disinfected but have exceeded their expiration time (e.g., probes stored in a contaminated environment for too long after disinfection). This forces the device to be used within the safe time window after disinfection, thereby continuously ensuring the safety of the probe during use in a dynamically changing clinical environment. For example, if a disinfected probe is left in the base for 3 hours before being used, the host calculates a time difference of 180 minutes during reinstallation, exceeding the 120-minute validity period. Even if the verification code is correct, the host will determine that the disinfection has expired and requires re-disinfection and interlocking.

[0100] In an alternative approach, the method further includes:

[0101] While the otoscope main unit is in standby mode, the probe insertion status signal and the rate of change of ambient temperature and humidity are continuously monitored.

[0102] When the probe is detected to have been removed and the expected time interval between uses is less than a preset threshold, the UV lamp preheating circuit is activated in advance and a slightly positive pressure dry airflow is maintained in the chamber. At the same time, based on the pollution level and environmental conditions recorded at the end of the last use, the most likely applicable disinfection protocol template is preloaded into the cache.

[0103] When the probe is reinserted and the insertion status signal is stable, the sensor array is started to acquire data synchronously and the preloaded protocol is used as the initial guess value.

[0104] In this embodiment, by continuously monitoring the probe status and environmental changes in standby mode, the system can proactively identify the precursor event of the probe being removed, indicating impending use (and subsequent disinfection). This allows for advance prediction of disinfection needs and the pre-emptive deployment of some preparatory work (such as preheating, drying, and protocol preloading) to idle periods, significantly shortening the overall response time from probe insertion to disinfection initiation and improving equipment turnaround efficiency. This is particularly suitable for scenarios requiring rapid and continuous use, such as outpatient clinics. Simultaneously, it avoids energy waste and lamp life loss caused by unnecessary preheating cycles of the UV lamp during prolonged standby. When the probe is reinserted, the UV lamp is already at or near its optimal operating temperature, ensuring instantaneous dosage accuracy at the start of disinfection.

[0105] According to the solution provided by this invention, before disinfection is initiated, a sensor array installed on the detachable probe base of the otoscope synchronously collects contamination spectrum data, ultraviolet intensity reference data, disinfection temperature and humidity data, and probe insertion status signals from the endoscopic optical window at the probe tip to obtain an initial disinfection state vector. A dynamic contamination index is calculated based on the initial disinfection state vector, the probe's historical usage frequency, and adjacent usage time intervals. Basic disinfection parameters are matched according to the dynamic contamination index and a preset disinfection mapping table. The basic disinfection parameters are dynamically calibrated based on the degree of index deviation to generate a personalized disinfection protocol including irradiation mode and dosage. During the execution of the personalized disinfection protocol, process protection control is performed based on ultraviolet intensity reference data, disinfection temperature and humidity data, and preset thresholds. After disinfection, cumulative ultraviolet dose compliance verification and contamination spectrum data comparison verification are performed. When the compliance verification and comparison verification pass, a disinfection completion status and a cyclic verification code are written to the RFID chip on the probe, which is used for hardware interlocking of the otoscope circuitry when the probe is reinstalled. This invention significantly improves the reliability of the disinfection process and avoids the risk of cross-infection due to human negligence. Specifically, the personalized disinfection protocol intelligently matches the irradiation dose, power, duration, and mode (continuous / pulse / phased) based on the severity of contamination, probe material, and environmental conditions. This avoids the infection risk caused by insufficient disinfection and the equipment aging and energy waste caused by excessive disinfection. By comparing the deviation between the actual cumulative dose and the target value, the driving current or pulse duty cycle of the UV lamp is dynamically adjusted. Only after both verifications pass is the disinfection completion status and cycle verification code written to the probe's RFID chip, ensuring verifiable disinfection quality for each disinfection. When the probe is reinstalled into the host, the host must read the disinfection status and verification code from its chip via near-field communication and compare it with the locally calculated value, avoiding the risk of cross-infection due to human negligence.
