Description

Technical Field

[0001] This invention relates to the field of medical device management technology, and in particular to an intelligent management method and system for medical electronic devices. Background Technology

[0002] In modern medical environments, the use of medical electronic devices such as laryngoscopes, handheld ultrasound probes, and portable monitors is becoming increasingly frequent. These devices are typically characterized by high value, high usage frequency, and the need for regular charging, disinfection, and data export. Currently, hospitals rely heavily on manual registration, manual charging, separate disinfection, and manual data copying for the management of these devices, which presents the following problems:

[0003] Low management efficiency: Retrieval and return records rely on paper or simple electronic registration, which is prone to omissions and errors, and it is impossible to monitor the location and status of the equipment in real time;

[0004] Untimely equipment maintenance: Charging, disinfection, and data backup need to be performed separately, which is cumbersome and can easily lead to insufficient power, failure to disinfect, or data loss due to human negligence.

[0005] Difficulties in traceability: Incomplete equipment circulation records make it difficult to link operators, usage time, and equipment data, which is not conducive to medical quality analysis and accountability.

[0006] There is a risk of infection control: manual disinfection may have blind spots or insufficient time, increasing the risk of cross-infection;

[0007] Lack of transparency in equipment utilization: It is impossible to see in real time whether the equipment is available, which affects clinical scheduling and resource optimization.

[0008] In conclusion, there is an urgent need for a system and method that can automate and intelligently manage the entire lifecycle of medical electronic devices in order to improve the management level of medical devices and ensure medical safety and efficiency. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides an intelligent management method and system for medical electronic devices, aiming to solve the aforementioned problems.

[0010] On the one hand, this application provides an intelligent management method for medical electronic devices, including the following steps:

[0011] Step 1: Verify the identity of the person who takes / returns the medical electronic equipment using biometric technology;

[0012] Step 2: After successful identity authentication, the user is allowed to take or return the medical electronic device.

[0013] Step 3: During the return operation, the medical electronic device is forced to connect to the preset interface, triggering the automatic charging process, the automatic data collection process, and the automatic disinfection process;

[0014] Step 4: During the retrieval operation, unlock the corresponding storage unit, check the device retrieval status, and close the disinfection process;

[0015] Step 5: Monitor the charging status, storage location, and usage status of medical electronic devices in real time, and generate and store device retrieval and return records, status data, and related data collected;

[0016] Step 6: Display device-related information and support query operations through an interactive interface, forming a closed-loop autonomous management system for the entire lifecycle of medical electronic equipment. Identity authentication ensures operational compliance, and mandatory access and automatic triggering mechanisms enable fully automated processing of charging, disinfection, and data collection after device return. Real-time monitoring and recording functions make device status, location, and usage traceable throughout the entire process. Combined with a visual query interface, this constructs an intelligent management closed loop from retrieval to return, significantly improving the management efficiency, security, and availability of medical electronic equipment.

[0017] Furthermore, the identity authentication steps include:

[0018] Capture facial images of people using a camera;

[0019] Extract feature information from facial images and compare it with a pre-defined database of authorized personnel features;

[0020] If the similarity reaches the preset threshold, the identity authentication is deemed successful; if the threshold is not reached, 1-3 retries are allowed. If the retries still fail, the operation is rejected and an exception log is recorded.

[0021] Furthermore, the step of forcing the medical electronic device to connect to the preset interface is implemented through a USB insertion detection circuit, specifically including:

[0022] The USB insertion detection circuit determines whether medical electronic devices are effectively connected by detecting changes in the pin levels of the interface.

[0023] If an access signal is detected, the device is determined to be returned to its original position, triggering subsequent charging, disinfection, and data collection processes. If no valid access signal is detected, a prompt message is issued through the interactive interface, and the storage unit's locked state is not disabled.

[0024] Furthermore, the automatic charging process includes:

[0025] After the device is successfully connected, the charging module automatically outputs the appropriate voltage and current to power the medical electronic equipment.

[0026] The charging detection circuit collects battery voltage and charging current data in real time to determine the charging stage.

[0027] When the battery voltage is detected to have reached the full charge threshold and the charging current drops to the cutoff current, the system automatically switches to trickle charging or stops charging to prevent overcharging from damaging the device.

[0028] Furthermore, the automatic disinfection process is implemented using UVC ultraviolet lamps, specifically including:

[0029] After the device is returned to its proper position and the charging process is started, the UVC ultraviolet lamp will be activated after a delay of 10-30 seconds.

[0030] The UVC ultraviolet lamp has a wavelength range of 200-280nm and a disinfection time of 5-30 minutes. The lamp's working status is monitored in real time during the disinfection process.

[0031] If the device is detected to have been removed or the disinfection period has ended, immediately turn off the UVC ultraviolet lamp to ensure safe use.

[0032] Furthermore, the automatic data acquisition process includes:

[0033] Establish a communication connection between the management system and medical electronic equipment via USB bus;

[0034] Automatically read business data stored in medical electronic devices, including surgical images and device operation logs;

[0035] The read business data is associated with the device number, return time, and operator identity information for storage, supporting local storage and uploading to the hospital server for backup via the network.

[0036] Furthermore, the steps for displaying information related to the display device include:

[0037] The distribution of each storage unit in the cabinet, the type of corresponding medical electronic device, the charging status, and the data upload status are displayed graphically.

[0038] It supports querying retrieval and return records and related business data by device number, operator, and time range. Query results are displayed in list or detail page format.

[0039] Furthermore, it also includes exception handling steps:

[0040] When abnormalities such as overcurrent, overvoltage, UVC lamp failure, or poor interface contact are detected, an audible and visual alarm is immediately triggered, and the abnormality type and handling suggestions are displayed on the interactive interface.

[0041] The time of occurrence of the anomaly, the device number, and the anomaly information are recorded synchronously to form an anomaly log for later traceability; the medical electronic equipment includes, but is not limited to, medical laryngoscopes, handheld ultrasound probes, and portable monitors.

[0042] On the other hand, this application provides an intelligent management system for medical electronic devices, including:

[0043] Biometric module: Used to collect and verify the operator's identity information and output the identity authentication result;

[0044] Device access detection module: used to detect whether medical electronic equipment has been effectively returned and connected to the system;

[0045] Charging module: Used to provide adaptive charging services for returned medical electronic devices and monitor charging status in real time;

[0046] Disinfection module: Used to automatically disinfect returned medical electronic equipment;

[0047] Data acquisition module: used to read and store business data from medical electronic devices;

[0048] Status monitoring module: used to collect data on the storage location, charging status, and usage status of medical electronic devices in real time;

[0049] Data logging module: Used to store device retrieval and return records, status data, business data, and exception logs;

[0050] Interactive module: Used to display device-related information and support querying and input of operation commands;

[0051] Control module: It communicates with each of the above modules and controls each module to perform corresponding operations based on the identity authentication results and feedback signals from each module, thereby realizing a closed-loop autonomous management system.

[0052] Furthermore, the biometric module is a camera with a face recognition algorithm; the device access detection module is used to detect changes in pin levels to determine the access status; the charging module includes a USB hub, a USB charging circuit, and a charging detection circuit; the disinfection module is a UVC ultraviolet lamp assembly; the control module interacts with each module via an RS485 bus and a USB bus; the medical electronic equipment includes, but is not limited to, a medical laryngoscope, a handheld ultrasound probe, and a portable monitor.

[0053] The substantial effects of this invention:

[0054] 1. In this invention, the integrated process of biometric authentication, forced access detection, automatic charging, disinfection and data collection significantly reduces manual intervention and improves management efficiency and equipment turnover rate.

[0055] 2. In this invention, by using UVC ultraviolet lamps for automatic disinfection, it is ensured that the equipment is disinfected in a standardized manner after each return, reducing the risk of cross-infection; and through intelligent charging and status monitoring, it is ensured that the equipment has sufficient power, clear location, and is always in standby mode, thereby improving the clinical emergency response capability.

[0056] 3. In this invention, by automatically collecting equipment business data and storing it in association with operation records, it supports rapid query and traceability, providing data support for medical quality control, scientific research analysis and equipment maintenance; at the same time, by combining identity authentication, operation control, status monitoring and abnormal alarm, it forms a closed loop of autonomous management throughout the entire life cycle from retrieval to return, improving the standardization and intelligence level of hospital equipment management.

[0059] Figure 2 This is a block diagram of the principle of Example 2. Detailed Implementation

[0060] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0061] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0062] Example 1:

[0063] Reference Figure 1As shown, an intelligent management method for medical electronic devices includes the following steps:

[0064] Step 1: Verify the identity of the person who takes / returns the medical electronic equipment using biometric technology;

[0065] Step 2: After successful identity authentication, the user is allowed to take or return the medical electronic device.

[0066] Step 3: During the return operation, the medical electronic device is forced to connect to the preset interface, triggering the automatic charging process, the automatic data collection process, and the automatic disinfection process;

[0067] Step 4: During the retrieval operation, unlock the corresponding storage unit, check the device retrieval status, and close the disinfection process;

[0068] Step 5: Monitor the charging status, storage location, and usage status of medical electronic devices in real time, and generate and store device retrieval and return records, status data, and related data collected;

[0069] Step 6: Display relevant device information and support query operations through an interactive interface to form a closed loop of autonomous management of the entire life cycle of medical electronic equipment.

[0070] As one implementation method, biometric technology is facial recognition technology, and the identity authentication steps include:

[0071] Capture facial images of people using a camera;

[0072] Extract feature information from facial images and compare it with a pre-defined database of authorized personnel features;

[0073] If the similarity reaches the preset threshold (≥95%), the identity authentication is deemed successful; if the threshold is not reached, two retries are allowed. If the retries still fail, the operation is rejected and an exception log is recorded.

[0074] As one implementation method, the step of forcing medical electronic devices to connect to a preset interface is achieved through a USB insertion detection circuit, specifically including:

[0075] The USB insertion detection circuit determines whether medical electronic devices are effectively connected by detecting changes in the pin levels of the interface.

[0076] If an access signal is detected, the device is determined to be returned to its original position, triggering subsequent charging, disinfection, and data collection processes. If no valid access signal is detected, a prompt message is issued through the interactive interface, and the storage unit's locked state is not disabled.

[0077] As one implementation method, the automatic charging process includes:

[0078] Once the device is successfully connected, the charging module automatically outputs an appropriate voltage (5V / 9V) and current (0.5A-2A) to power the medical electronic equipment.

[0079] The charging detection circuit collects battery voltage and charging current data in real time to determine the charging stage (pre-charge, constant current, constant voltage).

[0080] When the battery voltage is detected to have reached the full charge threshold (e.g., 4.2V) and the charging current drops to the cutoff current (≤50mA), the device will automatically switch to trickle charging or stop charging to avoid overcharging and damaging the device.

[0081] As one implementation method, the automatic disinfection process uses UVC ultraviolet lamps, specifically including:

[0082] After the device is returned to its original position and the charging process is started, the UVC ultraviolet lamp will start after a 20-second delay.

[0083] The UVC ultraviolet lamp has a wavelength range of 240nm and a disinfection time of 15 minutes. The lamp's working status is monitored in real time during the disinfection process.

[0084] If the device is detected to have been removed or the disinfection period has ended, immediately turn off the UVC ultraviolet lamp to ensure safe use.

[0085] As one implementation method, to achieve precise infection control, the automated disinfection process adopts a tiered disinfection strategy, specifically including:

[0086] In the system backend, an infection risk level (such as "high risk", "medium risk" or "low risk") is preset for each type of medical electronic device or each storage unit.

[0087] When the device is returned and the disinfection process is triggered, the control module calls the preset disinfection parameters according to the risk level of the device or the storage unit it is connected to.

[0088] For example: for "high-risk" equipment (medical laryngoscope), the strongest disinfection intensity (such as full power of UVC lamp) and the longest duration (such as 30 minutes) should be implemented; for "medium-risk" equipment (such as handheld ultrasound probe), the standard disinfection intensity and duration should be implemented (such as 15 minutes); for "low-risk" equipment (such as some external sensors), rapid disinfection (such as 5 minutes) can be implemented or concentrated disinfection can be carried out only at fixed times every day.

[0089] The disinfection level, duration, and execution records are all stored in conjunction with the equipment retrieval and return records, forming a traceable closed-loop management system for infection control.

[0090] As one implementation method, the automatic data acquisition process includes:

[0091] Establish a communication connection between the management system and medical electronic equipment via USB bus;

[0092] Automatically reads business data stored in medical electronic devices, including surgical images and equipment operation logs, with image formats including JPG and MP4;

[0093] The read business data is associated with the device number, return time, and operator identity information for storage, supporting local storage and uploading to the hospital server for backup via the network.

[0094] As one implementation method, the interactive interface is an LCD touchscreen, and the steps for displaying device-related information include:

[0095] The distribution of each storage unit in the cabinet, the type of corresponding medical electronic device, the charging status (not charging / charging / fully charged), and the data upload status (not uploaded / uploading / completed) are displayed in a graphical way.

[0096] It supports querying retrieval and return records and related business data by device number, operator, and time range. Query results are displayed in list or detail page format.

[0097] As one implementation method, exception handling steps are also included:

[0098] When abnormalities such as overcurrent (>2.5A), overvoltage (>10V), UVC lamp failure, or poor interface contact are detected, an audible and visual alarm will be triggered immediately, and the type of abnormality and handling suggestions will be displayed on the interactive interface.

[0099] Synchronously record the time of the anomaly, the device number, and the anomaly information to form an anomaly log for later traceability.
