Description

Technical Field

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

[0002] As one of the most commonly used examination instruments in otolaryngology, the otoscope probe needs to be inserted directly into the patient's external auditory canal for optical imaging or video examination. Due to the unique environment of the external auditory canal, it often contains contaminants such as earwax, pus, bloodstains, fungal or bacterial biofilms, and the probe is easily contaminated with various organic and microbial contaminants after use. If disinfection is not thorough, it can easily lead to cross-infection between patients, and even iatrogenic infections such as otitis externa and otitis media. In recent years, with the increasingly stringent standards for hospital infection control and the development of minimally invasive diagnostic and treatment techniques, the high-frequency use of the otoscope has placed higher demands on disinfection efficiency and safety.

[0003] Currently, clinical disinfection of otoscope probes mainly relies on the following methods. Traditional manual wiping disinfection involves operators using medical gauze or cotton swabs soaked in ethanol, isopropanol, or chlorine-containing disinfectant to manually wipe the probe surface, allowing it to air dry or wipe it dry with gauze. For probes with internal cavities, disinfectant is injected using a syringe for rinsing. The wiping force, range, and time cannot be standardized, making it particularly difficult to thoroughly clean the complex concave surface of the distal optical window, the gap between the probe tube and handle, and the small internal lighting or working channels. It is also difficult to visually determine whether microscopic contaminants (such as biofilms and trace amounts of blood) have been removed, making it difficult to meet the needs of continuous examinations for outpatients. A more effective method is to place the entire otoscope probe in a medical device disinfection cabinet (such as an ultraviolet disinfection cabinet or an ozone disinfection cabinet) for disinfection using ultraviolet light irradiation or ozone gas diffusion. The linear propagation characteristics of ultraviolet light mean that the back of the probe, deep crevices, and internal channels cannot receive effective irradiation doses. Ozone gas has limited penetration and concentration uniformity, resulting in weak removal of highly adhesive organic contaminants (such as dried earwax and blood clots). Contaminants, especially proteins, severely shield ultraviolet light or affect ozone activity, leading to disinfection failure. Furthermore, because disinfection parameters are fixed, they cannot be dynamically adjusted according to the type and degree of probe contamination, and they have poor adaptability to the geometry of different probe models (especially slender tube diameters and internal channels). For the slender internal channels of the otoscope, relying solely on hot air purging or negative pressure suction is insufficient to effectively remove trace amounts of liquid trapped in narrow areas such as behind the optical window due to capillary action; residual moisture is a major risk point for secondary contamination after disinfection.

[0004] To address the aforementioned issues, this invention proposes a multifunctional integrated disinfection method for otoscope probes, enabling comprehensive cleaning of the probe's outer surface, internal channels, and connecting gaps, thus solving the technical problem of difficulty in thoroughly drying capillary water accumulation in the slender internal channels. Summary of the Invention

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

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

[0007] The used otoscope probe is inserted into the contour carrier of the workstation, and the identification, model, cumulative number of uses and last disinfection record of the otoscope probe are read through the near field communication module; wherein, the contour carrier is equipped with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle;

[0008] Based on the otoscope probe's identification, model, cumulative usage count, and last disinfection record, personalized disinfection parameters matching the probe's geometry and contamination risk level are retrieved. Deionized water is injected into the sealed cleaning chamber, activating the bottom ultrasonic transducer at a frequency of 40±5 kHz for 60-120 seconds. Simultaneously, a camera is activated to capture surface images of the distal optical window area of ​​the otoscope probe, which are then input to a contamination identification module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and a contamination thermal map is output. If the contamination identification module determines that there is a high-risk residue in the optical window or tube wall, the cleaning time is automatically extended or an auxiliary pulsed water flow is activated to flush the probe's internal cavity channel according to the personalized disinfection parameters.

[0009] A composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt is pumped at a constant temperature of 35~40℃ and dynamically sprayed and rinsed for 180~300 seconds on the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier through a rotating nozzle, ensuring that the disinfectant solution covers the entire surface of the probe and the gaps at the connection end; at the same time, the data of conductivity, temperature and flow sensor are input to the disinfection efficacy prediction module in real time to dynamically estimate the inactivation probability of the target pathogen, and the disinfection time is increased or the liquid temperature is increased according to the inactivation probability;

[0010] The HEPA-filtered clean hot air system is activated, and the outer surface and internal microchannels of the otoscope probe are simultaneously blew through the directional air duct. The infrared thermal imaging module and the distributed humidity sensor work together to generate a dry state thermal map and input it into the anomaly detection module to identify areas prone to water accumulation at the edge of the optical window or the connection end to trigger a local replenishment blowing command.

[0011] The 265±5 nm UV-C LED array surrounding the contour-following vehicle is activated, and the contour-following vehicle is synchronously driven to rotate the otoscope probe at a uniform speed, ensuring that the slender tubular surface and optical window are uniformly irradiated.

[0012] In one alternative approach, simultaneously activating a camera to target the distal optical window area of ​​the otoscope probe to acquire a surface image and inputting it to a dirt recognition module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and outputting a contamination heat map further includes:

[0013] Once the otoscope probe is inserted into the contour carrier and axially fixed, the drive motor moves the camera module, which integrates a CMOS sensor and a ring LED fill light unit, along the guide rail to the theoretical position facing the far optical window of the probe.

[0014] The ring-shaped LED illumination unit is controlled to rapidly switch illumination in three preset modes. In the white light uniform illumination mode, a color image of the probe optical window and the adjacent inner wall of the lens barrel is acquired as the first channel image to observe obvious foreign objects and color changes. In the specific wavelength blue light excitation mode, the characteristic absorption and fluorescence quenching effect of hemoglobin in blood stains under blue light excitation is utilized to acquire a grayscale image as the second channel image to enhance the detectability of blood stain residue. In the coaxial polarized light illumination mode, the orthogonal setting of the polarizer and analyzer is used to suppress specular reflection light and acquire a third channel image including scattered light.

[0015] The first, second, and third channel images are input into the dirt recognition module, which outputs the probability distribution of each pixel belonging to earwax, cerumen crystals, bloodstains, biofilm, or cleanliness. Specifically, the first branch of the dirt recognition module processes the first channel image to extract the morphology, color, and spatial distribution features of the dirt; the second branch processes the second channel image to detect spectral absorption features related to hemoglobin; and the third branch processes the third channel image to extract microscopic texture features characterizing crystal roughness and biofilm viscosity.

[0016] Based on the probability distribution of each pixel and preset rules, a pollution heat map is generated. Bloodstains and biofilms are assigned the highest risk weight and are represented by the red high-temperature zone; earwax crystals are represented by the orange medium-temperature zone; earwax is represented by the yellow low-temperature zone; and cleanliness is represented by the blue background zone.

[0017] In one alternative approach, the disinfection efficacy prediction module has a built-in disinfection parameter knowledge base containing the target pathogen, wherein the disinfection parameter knowledge base stores the D and Z values ​​of hydrogen peroxide and dialkyl quaternary ammonium salt for each pathogen at different temperatures and concentrations.

[0018] The disinfection efficacy prediction module receives sensor data streams and calculates the actual cumulative disinfection dose within the current time window. Specifically, it converts the standard conductivity value into the equivalent molar concentration of hydrogen peroxide and quaternary ammonium salt based on the real-time conductivity concentration calibration curve. It dynamically corrects the D value of the standard temperature using the Arrhenius formula based on real-time temperature data. Finally, it integrates the corrected D value with the effective flow rate over time to calculate the theoretical logarithmic reduction in the number of pathogens received by the probe surface at the current moment.

[0019] In one alternative approach, generating a dry state thermal map in collaboration between an infrared thermal imaging module and a distributed humidity sensor further includes:

[0020] The infrared thermal imaging camera, located at the top of the sealed chamber of the workstation, works in conjunction with an array of microelectromechanical system (MEMS) humidity sensors embedded in preset positions on the contour-following vehicle. The infrared thermal imaging camera acquires the circumferential temperature field distribution image of the outer surface of the otoscope probe through a high-temperature resistant optical window at a sampling rate of no less than 5 frames per second. Eight to twelve miniature MEMS humidity sensors are installed at the bottom of the optical window retainer groove, the inside of the joint between the metal lens barrel and the plastic handle, and the liquid accumulation risk locations at the entrance of each working channel, respectively, to simultaneously collect the relative humidity value of the microenvironment.

[0021] By comparing the infrared temperature field of the temperature field distribution image with the theoretical temperature field predicted by the digital twin model, a temperature anomaly residual map is generated by calculating the temperature residual between the measured and predicted values ​​of each pixel region; the deviation is obtained by comparing the measured relative humidity value of each MEMS sensor with the predicted humidity curve.

[0022] If a certain area simultaneously shows a temperature anomaly residual map with a significant negative temperature and a consistently positive deviation in humidity from its neighboring sensors, the area is assigned a suspected liquid accumulation confidence level. Based on the level of the suspected liquid accumulation confidence level, the probe surface is divided into a well-dry area, a generally humid area, and a high-risk liquid accumulation area.

[0023] Based on the infrared thermal images of each region, the temperature anomaly residual map, and the confidence level of suspected liquid accumulation in the probe region, a dry state thermal map is generated; wherein, the dry state thermal map includes high-risk areas such as the capillary water accumulation area at the edge of the optical window and the liquid accumulation area at the root of the thread at the connection end.

[0024] In one alternative approach, the anomaly detection module's identification of areas prone to water accumulation, such as the edges of the optical window or the connection end, further includes:

[0025] The anomaly detection module performs spatial clustering on pixel clusters marked as high liquid accumulation risk areas in the thermal map of the dry state, extracts the risk cluster geometric parameters including the area, shape factor and spatial location of each cluster, and calls the water accumulation risk map library corresponding to the probe model to obtain the preset high-risk feature area geometric parameters of that model.

[0026] The shape similarity and positional overlap of the geometric parameters of the risk cluster and the geometric parameters of the high-risk feature area are calculated. When the positional overlap of the detected risk cluster and a certain preset high-risk feature area exceeds the first preset value and the shape similarity of their shape features reaches the second preset value, it is determined to be a suspected structural water accumulation area.

[0027] In one alternative approach, for a specific probe model, the set of stochastic differential equations for the state evolution of the disinfection process is as follows:

[0028]

[0029] in, Let t be the microscopic state vector of contaminants on the probe surface and within the microchannel at time t; A vector of personalized disinfection parameters to be optimized; This is a pollution risk feature vector extracted from historical data of the dirt identification module and the probe; For independent Wiener processes, representing process noise; For independent Wiener processes, representing observation noise; This is a nonlinear drift term function describing the state evolution; The observation function maps the microscopic state to the observable macroscopic sensor data dimension. , Here is the noise covariance matrix; Let t be the macroscopic vector of all sensor observation data of the workstation at time t.

[0030] In one alternative embodiment, the contouring vehicle is equipped with an electrically switchable microfluidic interface array, which forms a liquid-tight connection with the electrical / pneumatic connection port at the tail of the otoscope probe and dynamically reconstructs the internal fluid pathway during the disinfection process.

[0031] When the near-field communication module identifies the probe model, the workstation controller drives the micro-solenoid valve group to open the microchannel path matching the probe model, allowing the composite disinfectant to be injected into the probe's internal working channel or the illumination fiber optic sleeve through the elastic sealing joint of the conformal carrier. During the ultrasonic cleaning and hot air drying stages, the on / off state of the microchannel interface is switched to achieve internal cavity irrigation and rinsing and negative pressure suction assisted drainage, respectively. The negative pressure suction is provided by a micro diaphragm pump located at the bottom of the workstation, and its start and stop sequence is synchronized with the hot air purging to form a directional airflow in the microchannel behind the optical window, preventing residual liquid from flowing back to the imaging optical path area due to capillary action.

[0032] In an alternative approach, after the camera module completes multispectral image acquisition, the method further includes:

[0033] If the area of ​​bloodstains or biofilm in the contamination heat map exceeds a preset threshold, the integrity detection subroutine of the internal illumination fiber of the probe is triggered. The detection subroutine supplies power to the probe through the conductive contacts of the contour carrier to activate its built-in LED light source, and captures the intensity distribution image of the light emitted from the optical window through the CMOS sensor in the camera module with the ring supplementary light unit turned off.

[0034] The intensity distribution image is compared with the standard spot template of the otoscope probe using structural similarity (SSIM). If the SSIM value is lower than the preset threshold or a local dark area appears at the edge of the spot, it is determined that there is contamination or micro-damage.

[0035] According to another aspect of the present invention, a multifunctional integrated disinfection device for an otoscope probe is provided, comprising:

[0036] The identification and positioning module is used to insert the used otoscope probe into the contour carrier of the workstation, and read the otoscope probe's identification, model, cumulative number of uses and last disinfection record through the near field communication module; wherein, the contour carrier is equipped with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle;

[0037] The pre-cleaning and evaluation module is used to retrieve personalized disinfection parameters that match the geometry and contamination risk level of the otoscope probe based on its identification, model, cumulative usage count, and last disinfection record. Deionized water is injected into the sealed cleaning chamber to activate the bottom ultrasonic transducer at a frequency of 40±5 kHz for 60-120 seconds. Simultaneously, a camera is activated to capture surface images of the distal optical window area of ​​the otoscope probe, which are then input to a contamination identification module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and a contamination thermal map is output. If the contamination identification module determines that there is a high-risk residue in the optical window or tube wall, it automatically extends the cleaning time or activates an auxiliary pulsed water flow to flush the probe's internal cavity channel according to the personalized disinfection parameters.

[0038] The dynamic disinfection and monitoring module is used to pump a composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt at a constant temperature of 35~40℃. It dynamically sprays and rinses the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier for 180~300 seconds through a rotating nozzle to ensure that the disinfectant solution covers the entire surface of the probe and the gaps at the connection end. At the same time, the conductivity, temperature and flow sensor data are input to the disinfection efficacy prediction module in real time to dynamically estimate the inactivation probability of the target pathogen and increase the disinfection time or increase the liquid temperature according to the inactivation probability.

[0039] The drying and status detection module is used to start the clean hot air system after HEPA filtration, and simultaneously blow the outer surface and internal microchannels of the otoscope probe through the directional air duct; the infrared thermal imaging module and the distributed humidity sensor work together to generate a dry status heat map and input it to the anomaly detection module to identify areas that are prone to water accumulation at the edge of the optical window or the connection end to trigger a local replenishment blowing command.

[0040] The ultraviolet irradiation enhancement module is used to activate the 265±5 nm UV-C LED array surrounding the contour-following vehicle, and synchronously drive the contour-following vehicle to rotate the otoscope probe at a uniform speed, ensuring that the slender tubular surface and optical window are irradiated uniformly.

[0041] 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;

[0042] The memory is used to store at least one executable instruction, which causes the processor to perform the operation corresponding to the above-described multifunctional integrated disinfection method for the otoscope probe.

[0043] According to the solution provided by the present invention, the used otoscope probe is inserted into the contour carrier of the workstation, and the identification, model, cumulative number of uses, and last disinfection record of the otoscope probe are read through the near-field communication module; wherein, the contour carrier is provided with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle; according to the identification, model, cumulative number of uses, and last disinfection record of the otoscope probe, personalized disinfection parameters matching the geometry and contamination risk level of the otoscope probe are retrieved; deionized water is injected into the sealed cleaning chamber to activate the bottom ultrasonic transducer at 40±5 The cleaning process is carried out at a frequency of kHz for 60-120 seconds. Simultaneously, a camera is activated to capture surface images of the distal optical window area of ​​the otoscope probe. These images are then input to a dirt identification module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and a contamination thermal map is output. If the dirt identification module determines that there is a high-risk residue on the optical window or tube wall, it automatically extends the cleaning time or activates an auxiliary pulsed water flow to rinse the probe's internal cavity channel according to the personalized disinfection parameters. A composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt is pumped at a constant temperature of 35-40℃, and dynamically sprayed through a rotating nozzle onto the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier. For 80-300 seconds, ensure the disinfectant covers the entire surface of the probe and the gaps at the connection end; simultaneously, input real-time data from conductivity, temperature, and flow sensors to the disinfection efficacy prediction module to dynamically estimate the inactivation probability of the target pathogen, and adjust the disinfection time or increase the liquid temperature based on the inactivation probability; activate the HEPA-filtered clean hot air system to simultaneously blow clean the outer surface and internal microchannels of the otoscope probe through a directional air duct; generate a dryness thermal map through the infrared thermal imaging module and distributed humidity sensors and input it to the anomaly detection module to identify areas prone to water accumulation at the edges of the optical window or the connection end to trigger a local supplementary blowing command; activate the 265±5 nm UV-CLED array surrounding the contour carrier, synchronously driving the contour carrier to rotate the otoscope probe at a uniform speed, ensuring uniform irradiation of the slender tubular surface and optical window. This invention achieves comprehensive cleaning of the probe's outer surface, internal channels, and connection gaps, solving the technical problem of incomplete drying of capillary water accumulation in slender internal channels.

[0051] 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.

[0052] Figure 1 , Figure 2 The flowcharts of the multifunctional integrated disinfection method for an otoscope probe according to embodiments of the present invention are shown respectively. Figure 1 , two Specifically, such as Figure 1 , Figure 2 As shown, it includes the following steps:

[0053] Step S101: Insert the used otoscope probe into the contour carrier of the workstation, and read the otoscope probe's identification, model, cumulative number of uses, and last disinfection record through the near-field communication module; wherein, the contour carrier is provided with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle.

[0054] In this embodiment, the near-field communication (NFC) module automatically reads the probe's identification, model, cumulative usage count, and last disinfection record, avoiding resource waste or insufficient disinfection caused by a "one-size-fits-all" approach. The contour carrier has built-in conductive contacts and positioning slots, ensuring axial fixation of the probe after insertion and forcing its optical window towards the cleaning nozzle. This significantly improves the consistency of placement each time, ensuring alignment during cleaning, imaging, drying, and UV irradiation processes, which is especially crucial for slender, tubular otoscope probes. No manual input of the model number or manual adjustment of the orientation is required; insertion automatically completes identification and posture calibration, greatly reducing the operational threshold and minimizing human error (such as reverse insertion or misuse), while also accelerating the overall disinfection process, making it suitable for high-frequency clinical scenarios. Automatic reading of cumulative usage counts and historical disinfection records facilitates assessment of whether the probe is nearing the end of its lifespan or has any abnormal disinfection records. In actual deployment, the workstation is equipped with a contour carrier specifically designed for otoscope probes. The carrier's internal contour strictly matches the external dimensions of a specific probe model and includes metal positioning slots and an array of flexible conductive contacts. When medical staff insert the used probe into the carrier, the NFC chip at the probe's tail approaches the carrier's built-in read / write antenna, automatically and wirelessly transmitting its electronic tag information (including ID, product model, batch number, cumulative number of uses, and the timestamp and result of the most recent disinfection). The flange or keyway on the probe's outer wall engages with the carrier's positioning slot, forcing it to rotate to a preset angle, ensuring that the distal optical window is precisely aligned with the cleaning nozzle above or to the side. Simultaneously, the electrode at the probe's tail makes physical contact with the carrier's conductive contacts, which can be used for power supply (e.g., activating the built-in LED for spot detection) and also as an auxiliary positioning method to enhance axial stability. For example, an ENT department uses multiple models of otoscope probes daily. When a nurse inserts a type A probe that has been used 127 times into the workstation, the contour carrier immediately reads the probe model as "A-2025" via NFC, noting that it has been used 127 times and was last disinfected 6 hours ago and passed the test. Because the optical window of the Type A probe is located at the lower front, the positioning slot design of the carrier causes it to automatically rotate 30 degrees after insertion, ensuring that the window is directly aligned with the main nozzle inside the ultrasonic cleaning chamber. Simultaneously, based on the "127 cycles" data, it is determined that the probe is nearing its recommended lifespan (150 cycles), and is automatically marked for immediate replacement after subsequent disinfection. If a Type B probe is mistakenly inserted into a Type A carrier, it may not be fully inserted due to shape mismatch, or although it may be inserted, the NFC reading model may not match the carrier's preset, triggering an alarm indicating a model mismatch. This prevents incorrect disinfection procedures from starting, avoiding equipment damage or disinfection failure.

[0055] Step S102: Based on the identification, model, cumulative number of uses, and last disinfection record of the otoscope probe, retrieve personalized disinfection parameters that match the geometry and contamination risk level of the otoscope probe; inject deionized water into the sealed cleaning chamber and activate the bottom ultrasonic transducer at a frequency of 40±5 kHz for 60~120 seconds; simultaneously activate the camera to aim at the distal optical window area of ​​the otoscope probe to acquire surface images and input them to the dirt identification module deployed at the edge to distinguish earwax, cerumen crystals, bloodstains, or biofilm and output a contamination thermal map; if the dirt identification module determines that there are high-risk residues in the optical window or tube wall, automatically extend the cleaning time or activate auxiliary pulse water flow to rinse the probe's inner cavity channel according to the personalized disinfection parameters.

[0056] In this embodiment, based on the probe's identification, model, number of uses, and historical disinfection records, personalized disinfection parameters matching its geometry (such as length, inner diameter, and optical window position) and clinical usage scenario (such as pediatric / adult, whether it comes into contact with bleeding, etc.) can be dynamically invoked. This avoids incomplete cleaning of complex structures or over-processing of low-risk probes. During the ultrasonic cleaning stage, a camera is simultaneously activated to acquire images of the optical window, and a contaminant identification module deployed at the edge analyzes the type of contaminant (earwax, cerumen crystals, bloodstains, biofilm) in real time to form a contamination heat map. This upgrades traditional fixed-duration cleaning to on-demand responsive cleaning, significantly improving the targeting and effectiveness of the cleaning. When high-risk contaminants such as bloodstains or biofilms are identified, the ultrasonic cleaning time can be automatically extended or an auxiliary pulsed water flow can be activated to flush the inner cavity channel, effectively removing highly adhesive and pathogenic residues and reducing the risk of cross-infection. This is especially suitable for probe treatment after use by patients with ear canal bleeding or chronic otitis media. The ultrasonic frequency is set to 40±5 kHz, which effectively removes organic contaminants while avoiding cavitation damage to precision optical components (such as lens coatings and fiber end faces); when used with deionized water, it prevents scale buildup and ensures long-term equipment reliability.

[0057] Specifically, after the otoscope probe is inserted and identified, the workstation's main control system retrieves the corresponding personalized disinfection parameter set from the local database or cloud knowledge base. This includes the recommended ultrasonic cleaning duration (60–120 seconds), whether to activate internal cavity flushing, and the intensity of the pulsed water flow. A fixed amount of deionized water is automatically injected into the sealed cleaning chamber, and the bottom ultrasonic transducer activates at a frequency of 40±5 kHz, generating a uniform cavitation field to physically peel away the probe's outer surface and proximal tube wall. Simultaneously, the camera module moves along the guide rail to a preset position, aligns with the probe's distal optical window, captures its surface image, and transmits it in real-time to the contaminant recognition module deployed in the edge computing unit. The contaminant recognition module analyzes the image (e.g., color, texture, spectral response) to determine the contaminant category and generates a contamination heatmap with risk weights. If the thermal image shows red (high-risk) areas (such as bloodstains or biofilm) on the optical window or inner wall, an enhanced cleaning strategy is triggered. For example, the ultrasound session is extended from the original 90 seconds to 120 seconds, or a miniature solenoid valve is activated to inject pulsed water flow into the probe's internal channel through the microfluidic interface of the contour carrier, achieving coordinated internal and external rinsing. The entire process requires no manual intervention and is controlled collaboratively by sensors and actuators.

[0058] For example, a hospital uses a slender pediatric otoscope probe (model P-Child), with an inner diameter of only 1.2 mm, commonly used for children with cerumen impaction. This probe is prone to leaving behind viscous cerumen and trace amounts of blood. After one use, the probe was inserted into a sterilization workstation. Its NFC tag was read, identifying it as a P-Child model, with a cumulative use of 85 times and a previous sterilization pass. Based on pre-stored parameters, the initial ultrasonic cleaning time was set to 100 seconds. After cleaning began, the camera captured an image of the optical window. The contaminant identification module analyzed the window edge and found a small dark red area exhibiting typical absorption characteristics in the blue light excitation channel, classifying it as blood, indicating a high risk level. The ultrasonic cleaning was automatically extended to 120 seconds, and an auxiliary pulsed water flow was activated. High-frequency pulsed deionized water was injected into the 1.2 mm inner cavity through the microchannel interface to flush away the trace amounts of blood adhering to the illumination fiber optic sleeve. After cleaning, the contamination heat map was updated, showing that the high-risk area had been eliminated, and the process proceeded to the next sterilization stage. If an adult probe (model A-Adult) is inserted for routine examinations only and there is no history of bleeding, and the image shows only yellow earwax, then maintain the original timing and do not use internal irrigation to save water and electricity resources and shorten turnaround time.

[0059] In one alternative approach, simultaneously activating a camera to target the distal optical window area of ​​the otoscope probe to acquire a surface image and inputting it to a dirt recognition module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and outputting a contamination heat map further includes:

[0060] Once the otoscope probe is inserted into the contour carrier and axially fixed, the drive motor moves the camera module, which integrates a CMOS sensor and a ring LED fill light unit, along the guide rail to the theoretical position facing the far optical window of the probe.

[0061] The ring-shaped LED illumination unit is controlled to rapidly switch illumination in three preset modes. In the white light uniform illumination mode, a color image of the probe optical window and the adjacent inner wall of the lens barrel is acquired as the first channel image to observe obvious foreign objects and color changes. In the specific wavelength blue light excitation mode, the characteristic absorption and fluorescence quenching effect of hemoglobin in blood stains under blue light excitation is utilized to acquire a grayscale image as the second channel image to enhance the detectability of blood stain residue. In the coaxial polarized light illumination mode, the orthogonal setting of the polarizer and analyzer is used to suppress specular reflection light and acquire a third channel image including scattered light.

[0062] The first, second, and third channel images are input into the dirt recognition module, which outputs the probability distribution of each pixel belonging to earwax, cerumen crystals, bloodstains, biofilm, or cleanliness. Specifically, the first branch of the dirt recognition module processes the first channel image to extract the morphology, color, and spatial distribution features of the dirt; the second branch processes the second channel image to detect spectral absorption features related to hemoglobin; and the third branch processes the third channel image to extract microscopic texture features characterizing crystal roughness and biofilm viscosity.

[0063] Based on the probability distribution of each pixel and preset rules, a pollution heat map is generated. Bloodstains and biofilms are assigned the highest risk weight and are represented by the red high-temperature zone; earwax crystals are represented by the orange medium-temperature zone; earwax is represented by the yellow low-temperature zone; and cleanliness is represented by the blue background zone.

[0064] In this embodiment, multi-mode illumination (white light, blue light excitation, and coaxial polarized light) effectively distinguishes different types of contaminants. For example, the characteristic absorption and fluorescence quenching effect of bloodstains under specific wavelengths of blue light significantly improve their detection sensitivity; coaxial polarized light can suppress specular reflection and enhance the capture of microscopic texture features such as crystal roughness and biofilm viscosity. By processing the generated first, second, and third channel images using the three illumination modes respectively, the contaminant recognition module can analyze them from the dimensions of morphology, color, spatial distribution, spectral absorption characteristics, and microscopic texture, ensuring accurate identification of common contaminants such as earwax, cerumen crystals, bloodstains, and biofilms. Converting the probability distribution of each pixel into an intuitive contamination heatmap and assigning different risk weights to different types of contaminants (e.g., bloodstains and biofilms are in the red high-temperature zone) helps analyze the contamination status of the probe surface and its potential risk level. The contamination heatmap not only allows for automatic adjustment of cleaning steps but also provides a basis for preventative maintenance. For example, when a long-standing, difficult-to-remove biofilm is found, it prompts the replacement of relevant components or the strengthening of daily cleaning procedures.

[0065] Specifically, after the otoscope probe is inserted into the contour carrier and axially fixed, the workstation's built-in motor drives the camera module to move along the guide rail to a preset position, ensuring the CMOS sensor is directly facing the probe's distal optical window. In white light uniform illumination mode, the camera captures color images of the probe's optical window and its surrounding area to observe obvious foreign objects and color changes. In specific wavelength blue light excitation mode, utilizing the unique response characteristics of hemoglobin to blue light, the camera acquires grayscale images to enhance the visibility of bloodstain residue. In coaxial polarized light illumination mode, the polarizer and analyzer settings reduce specular reflection, helping the camera capture more scattered light, thus better revealing the microstructure of crystals and biofilms. The collected images from the first, second, and third channels are sent to the contaminant recognition module. The three branches extract different types of information, calculate the probability of each pixel belonging to various contaminants, and map them onto a contamination heatmap according to preset rules. The contamination heat map visually displays the degree and type of contamination on the probe surface. For example, red represents the highest risk areas of bloodstains and biofilms, orange represents medium risk areas of earwax crystals, yellow marks low risk areas of earwax, and blue indicates clean areas.

[0066] In an alternative approach, after the camera module completes multispectral image acquisition, the method further includes:

[0067] If the area of ​​bloodstains or biofilm in the contamination heat map exceeds a preset threshold, the integrity detection subroutine of the internal illumination fiber of the probe is triggered. The detection subroutine supplies power to the probe through the conductive contacts of the contour carrier to activate its built-in LED light source, and captures the intensity distribution image of the light emitted from the optical window through the CMOS sensor in the camera module with the ring supplementary light unit turned off.

[0068] The intensity distribution image is compared with the standard spot template of the otoscope probe using structural similarity (SSIM). If the SSIM value is lower than the preset threshold or a local dark area appears at the edge of the spot, it is determined that there is contamination or micro-damage.

[0069] This embodiment not only focuses on the cleanliness of the probe surface but also further evaluates whether its optical function is impaired by residual contaminants (such as bloodstains and biofilms) or physical damage, improving the reliability of device reuse. By turning off external supplementary lighting and relying solely on the probe's own LED light source for imaging, ambient light interference can be effectively eliminated, highlighting the actual output state of the internal lighting system. Combined with SSIM structural similarity comparison, local dark areas or intensity unevenness in the light spot that are difficult to detect with the naked eye can be accurately captured, thereby detecting problems such as fiber contamination, microcracks, or loose interfaces at an early stage. Integrity testing is only initiated when the contamination heatmap shows that the area of ​​high-risk contaminants (bloodstains / biofilms) exceeds the standard, avoiding redundant testing of all probes and focusing on the situations most likely to affect clinical imaging quality. Using existing hardware (conductive contact power supply, CMOS sensor imaging), functional verification of key optical pathways can be completed without additional disassembly or dedicated testing equipment, reducing maintenance costs and extending probe lifespan. Integrating optical performance verification into the sterilization process ensures that each reused probe not only looks clean but also functions perfectly, meeting high-standard medical device reprocessing specifications (such as the requirements of the CDC and WHO for endoscopic instruments).

[0070] For example, an ENT specialist used a slender, tubular otoscope probe to examine the external auditory canals of several patients. One patient had minor bleeding in their ear canal, resulting in trace amounts of bloodstains and biofilm contamination on the probe's optical window. This was difficult to detect visually, but a contamination thermal map showed that the bloodstain area covered 7%, exceeding the 5% threshold. The workstation automatically triggered an illumination fiber integrity check program. After the probe was powered on, its built-in LED illuminated, and the CMOS sensor captured an image showing a significant dark area in the lower right quadrant. SSIM comparison showed a similarity of only 0.78, below the 0.85 threshold. This indicated that the probe's illumination fiber end face was partially covered by bloody biofilm or had minor scratches, thus avoiding misdiagnosis (such as missing a tympanic membrane perforation) or the risk of cross-infection due to uneven illumination.

[0071] In step S103, a composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt is pumped at a constant temperature of 35~40℃. The solution is dynamically sprayed and rinsed for 180~300 seconds on the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier through a rotating nozzle to ensure that the disinfectant solution covers the entire surface of the probe and the gaps at the connection end. At the same time, the conductivity, temperature and flow sensor data are input to the disinfection efficacy prediction module in real time to dynamically estimate the inactivation probability of the target pathogen. The disinfection time is increased or the liquid temperature is increased according to the inactivation probability.

[0072] In this embodiment, a composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt is used. Working synergistically at a mild temperature of 35–40°C, it combines strong oxidizing properties (hydrogen peroxide) with surface-active bactericidal capabilities (quaternary ammonium salt), effectively inactivating bacteria, viruses, fungi, and some spores. It covers common pathogens in ENT diagnosis and treatment (such as Staphylococcus aureus, influenza virus, and Pseudomonas aeruginosa), while avoiding thermal damage to the probe's optical / electronic components from high temperatures. A rotating nozzle enables multi-angle, continuous sweeping spray, combined with a microchannel interface embedded in the contour carrier, ensuring that the disinfectant not only covers the probe's outer surface but also penetrates structural dead zones such as connection gaps and snap-fit ​​grooves, solving the problem of cleaning blind spots that traditional immersion or static spraying cannot reach. A disinfection efficacy prediction module dynamically estimates the actual inactivation probability of the target pathogen under current conditions. If the safety threshold (such as 6-log reduction) is not reached, the rinsing time is automatically extended or the liquid temperature is appropriately increased, achieving on-demand disinfection while balancing safety and efficiency. To avoid a one-size-fits-all fixed disinfection time, the cumulative disinfection dosage is calculated based on the actual concentration, temperature, and flow rate, preventing overuse of disinfectant or energy waste, while reducing the risk of residue. The disinfection process is based on a quantifiable inactivation probability model, meeting the process validation requirements of the Medical Device Reprocessing Standard (ANSI / AAMI ST79).

[0073] Specifically, after the probe is inserted into the conformal carrier, its model and historical data are read via near-field communication to determine the applicable list of target pathogens (e.g., outpatient probes focus on controlling bacteria, while emergency probes require additional virus inactivation). The premixed solution of hydrogen peroxide (e.g., 0.5%) and dialkyl quaternary ammonium salt (e.g., 0.2%) in the workstation's storage tank is heated by a thermostat and stably maintained at 35–40°C. It is then pumped to the rotary nozzle by a peristaltic pump at a set flow rate (e.g., 50 mL / min). The rotary nozzle rotates uniformly around the probe axis (e.g., 30 revolutions per minute), forming a spiral liquid film covering the entire outer surface of the probe. Simultaneously, the microfluidic interface inside the conformal carrier connects to the probe tail, introducing some disinfectant into the internal channel for simultaneous internal and external rinsing. The initial total duration is set to 180 seconds. A conductivity sensor monitors the disinfectant ion concentration in real time to infer the molar concentration of the active ingredient; a temperature sensor monitors liquid temperature fluctuations; and a flow meter records the actual flow rate. Based on the built-in pathogen D / Z value knowledge base and combined with the Arrhenius equation to correct for temperature effects, the logarithmic reduction value corresponding to the current cumulative disinfection dose is calculated (e.g., 5.8-log for MRSA). If it is lower than the target value (e.g., 6-log), the rinsing time is automatically extended by 30-60 seconds, or the liquid temperature is raised to 40°C within the safety limit to accelerate the reaction.

[0074] For example, using the same otoscope probe to examine 10 patients consecutively, the 8th patient was diagnosed as a carrier of methicillin-resistant Staphylococcus aureus (MRSA). After ultrasonic cleaning, the probe entered the disinfection stage. After identifying the probe model, the disinfection parameters for MRSA (target 6-log reduction) were invoked, and the compound disinfectant was initiated with a 37°C, 180-second initial program for rotary spraying. The conductivity sensor detected that due to dilution from residual water in the previous cleaning, the disinfectant concentration was slightly lower than the nominal value (equivalent concentration only 90%). The disinfection efficacy prediction module calculated that under the current conditions, only 5.6-log inactivation could be achieved, which was not up to standard. An additional 45 seconds of rinsing time was automatically added, and the liquid temperature was fine-tuned to 39°C to compensate for the insufficient concentration. This confirmed that the MRSA inactivation probability corresponded to 6.1-log reduction, and the disinfection was deemed successful. This ensures that even with slight dilution of the disinfectant or environmental fluctuations, effective killing of high-risk pathogens can still be dynamically guaranteed, avoiding disinfection failures caused by fixed procedures and significantly improving the reliability of cross-infection prevention and control.

[0075] In one alternative approach, the disinfection efficacy prediction module has a built-in disinfection parameter knowledge base containing the target pathogen, wherein the disinfection parameter knowledge base stores the D and Z values ​​of hydrogen peroxide and dialkyl quaternary ammonium salt for each pathogen at different temperatures and concentrations.

[0076] The disinfection efficacy prediction module receives sensor data streams and calculates the actual cumulative disinfection dose within the current time window. Specifically, it converts the standard conductivity value into the equivalent molar concentration of hydrogen peroxide and quaternary ammonium salt based on the real-time conductivity concentration calibration curve. It dynamically corrects the D value of the standard temperature using the Arrhenius formula based on real-time temperature data. Finally, it integrates the corrected D value with the effective flow rate over time to calculate the theoretical logarithmic reduction in the number of pathogens received by the probe surface at the current moment.

[0077] In this embodiment, a microbial inactivation kinetic model based on the D-value (time required to kill 90% of microorganisms) and Z-value (temperature change required to change the D-value by one logarithmic unit) makes the disinfection effect calculable and verifiable. The concentration of the disinfectant may deviate from the nominal value due to dilution and degradation, and the ambient temperature may also fluctuate. The molar concentration of the active ingredient is back-calculated in real time using conductivity, and the D-value is dynamically corrected using the Arrhenius formula in conjunction with the measured temperature, ensuring that the inactivation assessment is always based on real-world conditions, not ideal assumptions. The knowledge base pre-stores the D / Z parameters of various clinically relevant pathogens (such as Staphylococcus aureus, Escherichia coli, influenza virus, and Pseudomonas aeruginosa) under different temperature / concentration combinations, accurately assessing the inactivation level of key pathogens for specific usage scenarios or probe historical exposure risks. Each disinfection process generates an electronic report containing the actual cumulative disinfection dose and the logarithmic inactivation value of each pathogen, meeting the requirements of hospital infection control standards (such as CDC and ISO 17664) for verification and recording of reprocessing processes, facilitating quality management.

[0078] Step S104: Start the clean hot air system after HEPA filtration and simultaneously blow the outer surface and internal microchannels of the otoscope probe through the directional air duct; generate a dry state thermal map through the infrared thermal imaging module and the distributed humidity sensor and input it into the anomaly detection module to identify areas prone to water accumulation at the edge of the optical window or the connection end to trigger a local replenishment blowing command.

[0079] In this embodiment, as Figure 3 As shown, the clean hot air from the directional air duct not only acts on the outer surface of the probe but also enters the internal microchannels (such as the illumination fiber optic sleeve and working channel) through the microchannel interface of the contour carrier, achieving synchronous blowing from the inside out. This significantly shortens the drying time and avoids the problem of residual moisture in the internal cavity caused by traditional unidirectional blowing. The hot air is filtered through HEPA (High-Efficiency Particulate Air) to ensure that the blowing airflow itself is sterile and dust-free, eliminating secondary contamination. At the same time, thorough drying eliminates the humid environment, blocking the risk of residual pathogens surviving or forming biofilms in the probe gaps. By analyzing temperature field anomalies and humidity deviations, areas of capillary water accumulation invisible to the naked eye (such as the edge of the optical window and the root of the thread) are identified, and localized enhanced blowing is automatically triggered. Thorough drying prevents corrosion of metal parts, mold growth on optical components, or oxidation of electronic contacts caused by moisture retention.

[0080] For example, after examining a patient with cerumen impaction, a large amount of moist cerumen adhered to the area around the optical window of an otoscope probe. Despite ultrasonic cleaning and rinsing with disinfectant, trace amounts of moisture remained in the micron-sized gap between the optical window and the metal barrel, forming capillary water accumulation. After hot air drying was initiated, the infrared camera detected that the temperature at the edge of the optical window remained approximately 4°C lower than the main barrel, indicating that moisture was still evaporating and absorbing heat in that area. The MEMS humidity sensor installed at the bottom of the retaining ring groove read 65% RH, significantly higher than the 35% RH in other areas. This area was identified as a high-risk area for fluid accumulation and highlighted in red on the thermal map of the dried state. The anomaly detection module triggered a local supplemental blowing command, directionally increasing the hot air flow and velocity in that area for 30 seconds. After supplemental blowing, the temperature in this area rose back to match the main body, the humidity dropped to 38% RH, and the thermal map turned blue, confirming successful drying. Without this intelligent drying method, residual moisture could breed Pseudomonas aeruginosa or cause condensation that would affect image clarity during subsequent use.

[0081] In one alternative approach, generating a dry state thermal map in collaboration between an infrared thermal imaging module and a distributed humidity sensor further includes:

[0082] The infrared thermal imaging camera, located at the top of the sealed chamber of the workstation, works in conjunction with an array of microelectromechanical system (MEMS) humidity sensors embedded in preset positions on the contour-following vehicle. The infrared thermal imaging camera acquires the circumferential temperature field distribution image of the outer surface of the otoscope probe through a high-temperature resistant optical window at a sampling rate of no less than 5 frames per second. Eight to twelve miniature MEMS humidity sensors are installed at the bottom of the optical window retainer groove, the inside of the joint between the metal lens barrel and the plastic handle, and the liquid accumulation risk locations at the entrance of each working channel, respectively, to simultaneously collect the relative humidity value of the microenvironment.

[0083] By comparing the infrared temperature field of the temperature field distribution image with the theoretical temperature field predicted by the digital twin model, a temperature anomaly residual map is generated by calculating the temperature residual between the measured and predicted values ​​of each pixel region; the deviation is obtained by comparing the measured relative humidity value of each MEMS sensor with the predicted humidity curve.

[0084] If a certain area simultaneously shows a temperature anomaly residual map with a significant negative temperature and a consistently positive deviation in humidity from its neighboring sensors, the area is assigned a suspected liquid accumulation confidence level. Based on the level of the suspected liquid accumulation confidence level, the probe surface is divided into a well-dry area, a generally humid area, and a high-risk liquid accumulation area.

[0085] Based on the infrared thermal images of each region, the temperature anomaly residual map, and the confidence level of suspected liquid accumulation in the probe region, a dry state thermal map is generated; wherein, the dry state thermal map includes high-risk areas such as the capillary water accumulation area at the edge of the optical window and the liquid accumulation area at the root of the thread at the connection end.

[0086] In this embodiment, a fixed-focal-length infrared thermal imaging camera is installed at the top of the sealed chamber of the disinfection workstation, its field of view completely covering the entire surface of the probe on the contouring vehicle. The camera has a high-temperature resistant optical window with high infrared transmittance in front. Based on the common design of mainstream otoscope probes, miniature MEMS humidity sensors are pre-embedded at 8-12 key points on the contouring vehicle (e.g., the bottom of the retaining ring groove for fixing the optical lens, the inner side of the seam between the metal lens barrel and the plastic handle, and the inlet recess of the suction / injection channels). These sensors are connected to the workstation's main controller via flexible circuitry. A digital twin model is pre-established for each probe model, including the probe's 3D geometry, material thermophysical parameters, and a theoretical temperature field that can simulate the temperature change over time at various points on the probe surface under standard hot air purging parameters, as well as the predicted humidity curves for humidity decrease at each sensor point. After the hot air drying stage is initiated, the infrared thermal imaging camera begins continuous shooting at a set frequency (e.g., ≥5Hz) to acquire a video stream of the temperature field distribution on the probe surface. Simultaneously, all MEMS humidity sensors begin synchronously collecting relative humidity data from their respective microenvironments. A frame is extracted from the infrared video stream and pixel-wise aligned and compared with the theoretical temperature field image predicted by the digital twin model at the current moment. The difference between the measured temperature value and the theoretical prediction value for each pixel or region is calculated, generating a temperature anomaly residual map. Regions with negative residuals (measured temperatures significantly lower than predicted) may be abnormally low-temperature areas caused by heat absorption from water evaporation. The measured relative humidity value collected by each MEMS sensor is compared with the predicted humidity curve value at the current moment, and the deviation is calculated. A positive value (measured humidity consistently higher than predicted) indicates that the drying rate around that location is slower than expected. Judgment rules are set, for example: if an image region shows a significantly negative value region on the temperature residual map (e.g., below threshold T1) and the humidity deviation of the 1-2 MEMS sensors spatially closest to that region is consistently positive (e.g., above threshold H1 for a duration of Δt), then the region is judged to have suspected liquid accumulation, and a confidence score is calculated. Based on the confidence scores, the probe surface is divided into three zones: a well-dry area (low confidence), a moderately damp area (medium confidence), and a high-risk area for liquid accumulation (high confidence). By combining the original infrared thermal image (showing the actual temperature distribution), the temperature anomaly residual map (highlighting abnormal areas), and the calculated confidence scores for suspected liquid accumulation, a dry state thermal map is generated. This map is then overlaid in pseudo-color on the probe outline map, highlighting known high-risk areas such as the edge of the optical window and the root of the threaded connection.

[0087] In one alternative approach, the anomaly detection module's identification of areas prone to water accumulation, such as the edges of the optical window or the connection end, further includes:

[0088] The anomaly detection module performs spatial clustering on pixel clusters marked as high liquid accumulation risk areas in the thermal map of the dry state, extracts the risk cluster geometric parameters including the area, shape factor and spatial location of each cluster, and calls the water accumulation risk map library corresponding to the probe model to obtain the preset high-risk feature area geometric parameters of that model.

[0089] The shape similarity and positional overlap of the geometric parameters of the risk cluster and the geometric parameters of the high-risk feature area are calculated. When the positional overlap of the detected risk cluster and a certain preset high-risk feature area exceeds the first preset value and the shape similarity of their shape features reaches the second preset value, it is determined to be a suspected structural water accumulation area.

[0090] In this embodiment, for example, the otoscope probe (model E-205) uses a snap-fit ​​connection between its optical window and metal barrel. After long-term use, capillary water can easily accumulate at the bottom of the retaining ring groove due to micro-gaps. During a disinfection and drying process, the infrared thermal imaging and humidity sensor detected a low-temperature, high-humidity area below the optical window. The anomaly detection module clustered this area, resulting in a risk cluster with an area of ​​approximately 1.2 mm², crescent-shaped, located at the bottom of the window. Based on the E-205 model read by NFC, its exclusive water accumulation risk map was retrieved. The map pre-stores a standard high-risk area: located within ±0.5 mm of the bottom of the window, arc-shaped, with an area of ​​1.0–1.5 mm². The measured cluster and the standard area have an 85% overlap in position and an 82% similarity in shape. This area is determined to be a suspected structural water accumulation area. The directional hot air nozzle is activated to blow air into this area for an additional 30 seconds, and the area is marked as "E-205 probe #128 structural water accumulation tendency" in the disinfection log.

[0091] Step S105: Activate the 265±5 nm UV-C LED array surrounding the contouring vehicle, and synchronously drive the contouring vehicle to rotate the otoscope probe at a uniform speed to ensure that the slender tubular surface and optical window are uniformly irradiated.

[0092] In this embodiment, 265±5 nm is the peak wavelength for DNA / RNA absorption of ultraviolet light, which can efficiently destroy the genetic material of microorganisms and has a strong inactivation ability against bacteria, viruses (including enveloped and non-enveloped viruses) and fungal spores, significantly improving the overall disinfection reliability. The otoscope probe has a slender tubular structure, and static irradiation can easily lead to insufficient irradiation of the back surface or sidewalls. By synchronously driving the contour-following carrier to make the probe spin at a uniform speed, the entire outer surface (including the sides and edges of the optical window that are difficult to be directly exposed to) is periodically exposed to UV-C light, achieving 360° uniform irradiation without dead angles. Compared with broad-spectrum high-intensity ultraviolet lamps, the 265nm LED array wavelength can avoid the aging or damage to optical glass or coatings caused by high temperature or short-wavelength deep ultraviolet light (such as <250 nm), while the rotation mode reduces local overexposure. The spin speed and LED turn-on sequence are controlled in synergy to ensure that the UV dose received by each part is highly consistent in each disinfection.

[0093] For example, a hospital used a disinfection workstation to process a batch of pediatric otoscope probes (approximately 8 cm in length, 5 mm in diameter, with a sapphire optical window at the front). Due to the probes' slender shape and slightly curved front, traditional static UV disinfection often resulted in incomplete disinfection of the back and connection points. In this application, after the probe is inserted into the conformal carrier and pre-cleaned and dried, the UV stage begins. A surrounding 265 nm UV-C LED array is activated, driving the carrier to rotate the probe at a uniform speed of 20 rpm for 90 seconds. During rotation, the probe surface at each angle passes through the direct LED illumination area multiple times. Dosage simulation verification showed that the cumulative UV-C irradiation deviation across the entire surface was less than ±8%. After disinfection, microbial testing showed that the residual amounts of indicator bacteria / viruses such as Staphylococcus aureus and influenza virus were below the detection limit, and after three months of continuous use, there was no fogging or coating peeling on the optical window. This ensures thorough terminal disinfection while protecting delicate optical components, making it particularly suitable for high-frequency clinical scenarios.

[0094] In one alternative approach, for a specific probe model, the set of stochastic differential equations for the state evolution of the disinfection process is as follows:

[0095]

[0096] in, Let t be the microscopic state vector of contaminants on the probe surface and within the microchannel at time t; A vector of personalized disinfection parameters to be optimized; This is a pollution risk feature vector extracted from historical data of the dirt identification module and the probe; For independent Wiener processes, representing process noise; For independent Wiener processes, representing observation noise; This is a nonlinear drift term function describing the state evolution; The observation function maps the microscopic state to the observable macroscopic sensor data dimension. , Here is the noise covariance matrix; Let t be the macroscopic vector of all sensor observation data of the workstation at time t.

[0097] In this embodiment, the microscopic removal process of pollutants (such as dissolution, stripping, and inactivation) is formalized as a continuous-time stochastic system, enabling a more realistic portrayal of uncertain behavior under anti-coupling effects. By embedding personalized disinfection parameters and pollution risk characteristics into the state evolution equation, the cleaning / disinfection strategy is dynamically adjusted based on the specific conditions of each probe (such as the number of uses and historical pollution types). The observation equation establishes a mapping relationship between the microscopic pollutant state and macroscopic sensor readings (such as conductivity, temperature, and image features), providing data for real-time estimation of the pollutant residual state. By modeling process disturbances (such as water flow fluctuations and uneven pollutant distribution) and observation errors (such as sensor drift and image noise) through Wiener process modeling, stable performance can be maintained in uncertain environments.

[0098] In one alternative embodiment, the contouring vehicle is equipped with an electrically switchable microfluidic interface array, which forms a liquid-tight connection with the electrical / pneumatic connection port at the tail of the otoscope probe and dynamically reconstructs the internal fluid pathway during the disinfection process.

[0099] When the near-field communication module identifies the probe model, the workstation controller drives the micro-solenoid valve group to open the microchannel path matching the probe model, allowing the composite disinfectant to be injected into the probe's internal working channel or the illumination fiber optic sleeve through the elastic sealing joint of the conformal carrier. During the ultrasonic cleaning and hot air drying stages, the on / off state of the microchannel interface is switched to achieve internal cavity irrigation and rinsing and negative pressure suction assisted drainage, respectively. The negative pressure suction is provided by a micro diaphragm pump located at the bottom of the workstation, and its start and stop sequence is synchronized with the hot air purging to form a directional airflow in the microchannel behind the optical window, preventing residual liquid from flowing back to the imaging optical path area due to capillary action.

[0100] In this embodiment, traditional external rinsing is insufficient to remove contaminants and residual liquid from narrow internal cavities (such as illumination fiber optic sleeves and working channels). By liquid-tightly connecting and dynamically reconstructing the internal fluid pathways, cleaning fluid and airflow can directly enter the probe, significantly improving cleaning thoroughness. Different models of otoscope probes have varying internal interface layouts, channel numbers, and positions. The microfluidic interface array, combined with NFC identification and solenoid valve control, can automatically match the corresponding flow path, avoiding the high cost and complex management of dedicated fixtures. By simultaneously initiating negative pressure suction during the hot air drying stage and coordinating with the purge airflow to form a directional airflow, residual liquid is prevented from flowing back to the imaging optical path area behind the optical window due to capillary action, ensuring imaging clarity and equipment reliability.

[0101] According to the solution provided by the present invention, the used otoscope probe is inserted into the contour carrier of the workstation, and the identification, model, cumulative number of uses, and last disinfection record of the otoscope probe are read through the near-field communication module; wherein, the contour carrier is provided with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle; according to the identification, model, cumulative number of uses, and last disinfection record of the otoscope probe, personalized disinfection parameters matching the geometry and contamination risk level of the otoscope probe are retrieved; deionized water is injected into the sealed cleaning chamber to activate the bottom ultrasonic transducer at 40±5 The cleaning process is carried out at a frequency of kHz for 60-120 seconds. Simultaneously, a camera is activated to capture surface images of the distal optical window area of ​​the otoscope probe. These images are then input to a dirt identification module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and a contamination thermal map is output. If the dirt identification module determines that there is a high-risk residue on the optical window or tube wall, it automatically extends the cleaning time or activates an auxiliary pulsed water flow to rinse the probe's internal cavity channel according to the personalized disinfection parameters. A composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt is pumped at a constant temperature of 35-40℃, and dynamically sprayed through a rotating nozzle onto the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier. For 80-300 seconds, ensure the disinfectant covers the entire surface of the probe and the gaps at the connection end; simultaneously, input real-time data from conductivity, temperature, and flow sensors to the disinfection efficacy prediction module to dynamically estimate the inactivation probability of the target pathogen, and adjust the disinfection time or increase the liquid temperature based on the inactivation probability; activate the HEPA-filtered clean hot air system to simultaneously blow clean the outer surface and internal microchannels of the otoscope probe through a directional air duct; generate a dryness thermal map through the infrared thermal imaging module and distributed humidity sensors and input it to the anomaly detection module to identify areas prone to water accumulation at the edges of the optical window or the connection end to trigger a local supplementary blowing command; activate the 265±5 nm UV-CLED array surrounding the contour carrier, synchronously driving the contour carrier to rotate the otoscope probe at a uniform speed, ensuring uniform irradiation of the slender tubular surface and optical window. This invention achieves comprehensive cleaning of the probe's outer surface, internal channels, and connection gaps, solving the technical problem of incomplete drying of capillary water accumulation in slender internal channels.

[0102] Figure 4 A schematic diagram of the frame of a multifunctional integrated disinfection device for an otoscope probe according to an embodiment of the present invention is shown. The multifunctional integrated disinfection device for an otoscope probe includes:

[0103] The identification and positioning module 410 is used to insert the used otoscope probe into the contour carrier of the workstation and read the otoscope probe's identification, model, cumulative number of uses and last disinfection record through the near-field communication module; wherein, the contour carrier is provided with conductive contacts and positioning slots to ensure that the probe is axially fixed and the optical window faces the cleaning nozzle;

[0104] The pre-cleaning and evaluation module 420 is used to call personalized disinfection parameters that match the geometry and contamination risk level of the otoscope probe based on its identification, model, cumulative number of uses, and last disinfection record. Deionized water is injected into the sealed cleaning chamber to activate the bottom ultrasonic transducer at a frequency of 40±5 kHz for 60~120 seconds. Simultaneously, a camera is activated to capture surface images of the distal optical window area of ​​the otoscope probe and input them to a contamination identification module deployed at the edge to distinguish between earwax, cerumen crystals, bloodstains, or biofilm, and output a contamination thermal map. If the contamination identification module determines that there are high-risk residues in the optical window or tube wall, it automatically extends the cleaning time or activates an auxiliary pulsed water flow to rinse the probe's internal cavity channel according to the personalized disinfection parameters.

[0105] The dynamic disinfection and monitoring module 430 is used to pump a composite disinfectant solution of hydrogen peroxide and dialkyl quaternary ammonium salt at a constant temperature of 35~40℃. It dynamically sprays and rinses the outer surface of the otoscope probe and the microchannel interface embedded in the conformal carrier for 180~300 seconds through a rotating nozzle to ensure that the disinfectant solution covers the entire surface of the probe and the gaps at the connection end. At the same time, it inputs the data of conductivity, temperature and flow sensor to the disinfection efficacy prediction module in real time to dynamically estimate the inactivation probability of the target pathogen and increase the disinfection time or increase the liquid temperature according to the inactivation probability.

[0106] The drying and status detection module 440 is used to start the clean hot air system after HEPA filtration, and simultaneously blow the outer surface and internal microchannel of the otoscope probe through the directional air duct; the infrared thermal imaging module and the distributed humidity sensor work together to generate a drying status thermal map and input it to the anomaly detection module to identify the edge of the optical window or the connection end where water is easy to accumulate, so as to trigger a local replenishment blowing command.

[0107] The ultraviolet irradiation enhancement module 450 is used to activate the 265±5 nm UV-C LED array surrounding the contouring vehicle, and synchronously drive the contouring vehicle to rotate the otoscope probe at a uniform speed to ensure that the slender tubular surface and optical window are irradiated uniformly.

The infrared thermal imaging camera acquires the circumferential temperature field distribution image of the outer surface of the otoscope probe through a high-temperature resistant optical window at a sampling rate of no less than 5 frames per second. Eight to twelve miniature MEMS humidity sensors are installed at the bottom of the optical window retainer groove, the inside of the joint between the metal lens barrel and the plastic handle, and the liquid accumulation risk locations at the entrance of each working channel, respectively, to simultaneously collect the relative humidity value of the microenvironment. By comparing the infrared temperature field of the temperature field distribution image with the theoretical temperature field predicted by the digital twin model, a temperature anomaly residual map is generated by calculating the temperature residual between the measured and predicted values ​​of each pixel region; the deviation is obtained by comparing the measured relative humidity value of each MEMS sensor with the predicted humidity curve. If a certain area simultaneously shows a temperature anomaly residual map with a significant negative temperature and a consistently positive deviation in humidity from its neighboring sensors, the area is assigned a suspected liquid accumulation confidence level. Based on the level of the suspected liquid accumulation confidence level, the probe surface is divided into a well-dry area, a generally humid area, and a high-risk liquid accumulation area. Based on the infrared thermal images of each region, the temperature anomaly residual map, and the confidence level of suspected liquid accumulation in the probe region, a dry state thermal map is generated; wherein, the dry state thermal map includes high-risk areas such as the capillary water accumulation area at the edge of the optical window and the liquid accumulation area at the root of the thread at the connection end.
