Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an intelligent sterile treatment tray management system and method based on the Internet of Things. Background Art

[0002] Currently, various injectable drugs must be stored in sterile treatment trays after preparation. However, during use, the drugs cannot be administered in time due to various factors, or even forgotten to be used during busy work, resulting in adverse consequences such as treatment delays and nursing errors.

[0003] The sterile trays under existing technology lack the function of binding drug information, and there is a risk of disconnection between "material-drug-person" information. At the same time, there is a time blind spot in manually recording the timeliness of drugs (for example, if the drug expires 4 hours after configuration, it cannot be traced). In addition, the existing sterile trays lack disinfection devices and cannot provide a disinfection environment within the drug configuration time. At the same time, there are hidden dangers in the safety of drug use.

[0004] The utility model with publication number CN222367794U discloses a sterile tray with an expiration date reminder function, comprising a sterile tray and a detachable reminder module disposed on the sterile tray; the reminder module comprises a housing, a controller, a wireless communication module, a display light, and a button disposed on the surface of the housing; the controller is electrically connected to the wireless communication module, the display light, and the button; the display light comprises a green light for indicating within the expiration date and a red light for indicating beyond the expiration date; the housing is detachably fixed to the sterile tray by magnetic adsorption. However, its function is relatively simple, and it cannot provide a disinfected environment during the drug preparation time. As a result, the safety of the entire sterile tray medication process cannot be guaranteed, and the efficiency is low. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] Example 1

[0036] In this embodiment, an intelligent sterile treatment tray management system based on the Internet of Things is adopted. Figure 1 As shown, the management system includes: a cabinet 1, a multimodal scanning module 2, an environmental monitoring module 3, a control processing module and an alarm module;

[0037] Specifically, it includes: a sterile storage cabinet 1; a multimodal scanning module 2 (including a barcode reader and an RFID reader / writer) integrated in the cabinet 1; an environmental monitoring module 3 (temperature and humidity sensors, ultraviolet intensity sensors, and air particle counters); a control and processing module (including a clock module, a storage module, and a Bluetooth 5.3 communication module); an alarm module (an LED indicator array, a tactile alarm module, and an audible and visual alarm); and lockable universal wheels can also be provided at the bottom of the cabinet 1 to facilitate the movement of the cabinet 1.

[0038] The intelligent sterile treatment tray management system realizes three-level safety verification, namely drug level, operation level and environment level, by setting up a multimodal scanning module 2, an environmental monitoring module 3, a control processing module and an alarm module;

[0039] Drug-level security verification ensures the accuracy of drug information on the treatment tray. Multimodal scanning module 2 performs barcode scanning, QR code scanning, or NFC / RFID dual-mode scanning. Each drug package is printed with a unique barcode or QR code, which contains detailed information such as the drug name, strength, production date, expiration date, production batch, and approval number. When a drug is placed on the treatment tray, multimodal scanning module 2 quickly scans the drug's barcode or QR code. The system then interprets the captured QR code and compares it with the drug's standard information stored in a database. A successful match indicates that the drug meets the requirements. If a discrepancy occurs, the system will immediately issue an alarm, indicating a problem with the drug, such as counterfeit, expired, or incorrectly entered drug information. NFC (Near Field Communication) / RFID (Radio Frequency Identification) dual-mode scanning verification is a more advanced and precise scanning method, with a scanning accuracy of up to ±0.1mm. Some medications have NFC (near-field communication) or RFID (radio frequency identification) tags embedded in their packaging. These tags store drug-related data similar to, but richer than, QR codes. NFC / RFID dual-mode scanning devices can accurately identify these tags, communicate with them via radio frequency signals, and quickly read the information within. Compared to QR code scanning, this method eliminates the need for precise alignment, allowing effective reading even when the medication is positioned slightly off-center, significantly improving scanning efficiency and accuracy. Similarly, the system compares and verifies the read information against standard data in a database to further ensure the accuracy and authenticity of the drug information.

[0040] Operational-level security verification aims to confirm the legitimacy and operational authority of medical personnel using the treatment tray. It utilizes multi-factor authentication methods, such as fingerprint or ID badges. Before using the treatment tray, medical personnel must place their finger on the fingerprint recognition area of the multimodal scanning module 2. Fingerprint recognition technology analyzes the surface texture of the finger to generate a fingerprint feature template. The system compares the fingerprint feature template collected in real time with the medical personnel's fingerprint information pre-stored in the database. Only when the match reaches a set threshold is the medical personnel's identity deemed legitimate and allowed to proceed. This method is highly accurate and secure, as each person's fingerprint is unique and immutable throughout their life, effectively preventing others from impersonating them. In addition to fingerprint recognition, medical personnel can also authenticate their identity by swiping their ID badges. ID badges typically use RFID (Radio Frequency Identification) technology and store information such as the medical personnel's name, department, employee number, position, photo, and operational permissions. When the ID badge is brought close to the RFID sensing area of the multimodal scanning module 2, the module reads the information on the badge. The system not only verifies the authenticity of the ID card to prevent the use of forged ID cards, but also determines whether the medical staff has the authority to perform the current operation on the treatment tray based on the read operation permission information.

[0041] Environmental-level safety verification is primarily performed through the temperature and humidity sensors in the environmental monitoring module 3, which monitor the temperature and humidity of the treatment tray's environment in real time to ensure that the drug storage and medical operation environments meet the requirements. The temperature and humidity sensors are installed inside the cabinet 1 and can continuously and accurately measure the ambient temperature and humidity values. Different drugs have specific requirements for the temperature and humidity of the storage environment. For example, some biological products need to be stored in a low-temperature environment of 2-8°C, while some antibiotics are more sensitive to humidity. Excessively high or low humidity can affect the quality of the drugs. The temperature and humidity sensors transmit the real-time measured temperature and humidity data to the control and processing module. The control and processing module pre-sets the temperature and humidity threshold ranges suitable for drug storage and medical operations. When the data from the temperature and humidity sensors exceeds the set threshold range, the system immediately triggers the alarm module and issues an alarm signal. The alarm can be in the form of a loud sound and flashing lights from an audible and visual alarm to remind medical staff of abnormal ambient temperature and humidity. At the same time, the system also sends the alarm information to the mobile terminals of relevant managers through the Internet of Things, so that timely measures can be taken to adjust the ambient temperature and humidity, such as turning on the air conditioner to adjust the temperature, using a dehumidifier or humidifier to adjust the humidity, etc., to ensure that the environment in the treatment tray is always in a safe and appropriate state, and to ensure the quality of drugs and the smooth progress of medical operations.

[0042] Before the medicine is placed in the sterile tray, its original expiration date information is scanned by the multimodal scanning module 2 and transmitted to the control processing module for expiration date management.

[0043] When the drug configuration is completed, the system will start the countdown to the preset validity period after the drug is opened. Among them, for some common drugs, such as some temporarily configured solutions, drugs used in specific emergency treatment scenarios, etc., the preset validity period is automatically set to 4 hours. The system uses the control processing module to accurately record the time elapsed from the moment the drug is opened, update the remaining validity period in real time, and clearly display it on the terminal application of the associated medical staff, which can be viewed at any time. Because different drugs have different characteristics and usage requirements, the system also provides the function of setting an expiration date. Medical staff can set the preset validity period after the drug is opened through the operation interface equipped with the treatment tray or the connected mobile terminal application according to actual conditions, such as special storage conditions of the drug, clinical experience judgment, etc. This flexible setting method fully meets the needs of complex and diverse clinical drug use scenarios.

[0044] The core of compound warnings based on expiration date information is to implement differentiated warning strategies based on the different characteristics of the drugs. Taking antibiotics as an example, given that their efficacy may decline rapidly as they approach their expiration date, and the use of expired antibiotics may pose serious medical risks, the system defaults to issuing a warning 30 minutes in advance. When the remaining effective time of an antibiotic drug approaches 30 minutes, the system will issue a warning signal in a variety of ways. The treatment tray itself will activate an audible and visual alarm, emitting a loud beep and flashing a striking light; at the same time, mobile devices such as mobile phones and tablets of medical staff associated with the treatment tray will also receive push notifications, reminding them that the antibiotic is about to expire and needs to be properly used or disposed of as soon as possible.

[0045] In addition to preset warning times based on drug category characteristics, the system also allows medical staff to customize warning times based on actual work needs and the specific conditions of the drug. For example, for some expensive and scarce drugs, even if they are nearing their expiration date, they may still have a certain degree of efficacy. Medical staff can set the warning time one hour in advance based on the hospital's internal drug management regulations to allow more time to assess whether the drug is still safe to use or to make appropriate adjustments. This personalized setting not only ensures the safe use of drugs, but also improves the rational utilization of drug resources.

[0046] Through the coordinated operation of the initial expiration date, the expiration date after opening, and the composite warning, dynamic expiration date management provides a comprehensive, accurate, and flexible expiration date management service for the drugs in the intelligent sterile treatment tray, effectively ensuring the safety and effectiveness of clinical drug use.

[0047] This intelligent sterile treatment tray management system utilizes a solar-storage synergistic power supply. The power supply comprises a battery module and a photovoltaic module. The photovoltaic module utilizes photovoltaic panels (5) for energy conservation and a conversion efficiency of ≥23%. During intelligent power distribution, sunlight is prioritized for energy. The battery module uses batteries with a cycle life of ≥2000 cycles, serving only as a power buffer.

[0048] In the photovoltaic-storage system, the battery acts as a buffer backup power source. When sunlight is insufficient or the photovoltaic power module cannot meet the load demand, the battery discharges to power the system. When sunlight is sufficient, the excess energy generated by the photovoltaic panel 5 recharges the battery. A cycle count of 2000 or more means that the battery can undergo at least 2000 such charge and discharge cycles under normal use and charge and discharge conditions while maintaining a certain level of performance and capacity, providing stable power for the intelligent sterile treatment tray management system. This metric reflects the battery's durability and reliability; a higher number of cycles indicates a greater ability for the battery to provide effective power support throughout the system's lifespan.

[0049] The cabinet 1 in the intelligent sterile treatment tray management system is designed as a sterile barrier system:

[0050] The cabinet body 1 is made of medical-grade TPU (Thermoplastic Polyurethane) material with a light transmittance of ≥92% and a haze of ≤1% to achieve the effect of physical isolation. TPU is a polymer material with excellent properties such as high strength, high toughness, wear resistance, oil resistance, and water resistance. In the medical field, medical-grade TPU material has good biocompatibility, is non-irritating and non-toxic to human tissue, and can be used to manufacture various medical supplies. The use of medical-grade TPU material with a light transmittance of ≥92% and a haze of ≤1% to make the cabinet body 1 can not only meet the requirements of good light transmittance, making it easy to observe the situation inside the cabinet, but also because of its physical isolation effect, it can effectively prevent external pollutants from entering the interior of the cabinet body 1. At the same time, it also has the excellent properties of the TPU material itself, such as flexibility and durability, to meet actual use needs.

[0051] The cabinet 1 is equipped with a UV-CLED (Ultraviolet-C Light-Emitting Diode) array. UV-C has the shortest wavelength and the highest energy, and has a strong sterilization and disinfection ability. It can destroy the DNA or RNA structure in microorganisms, thereby achieving the purpose of dynamically killing bacteria, viruses and other pathogens. In the intelligent sterile treatment tray management system of this embodiment, a wavelength of 265nm is selected, and the irradiance is ≥90μW / cm 2 Ultraviolet light is used to sterilize the treatment tray to ensure that the treatment tray is in a sterile state and provide a safe environment for medical operations.

[0052] A Hall sensor is provided in the cabinet 1 to ensure that the ultraviolet light stops as soon as the cabinet is opened.

[0053] First, prepare: The Smart Sterile Treatment Tray Management System has a built-in light-powered charging panel. Store it at a nurse's station with ample sunlight for daily charging. Before use, check the side LED indicator (green indicates a full charge, yellow indicates a need for additional light). When not in use, it enters low-power mode, automatically sleeping and waking up when exposed to sunlight. Connect to the app via Bluetooth: Open the hospital's dedicated nursing app on your mobile device to automatically connect to the sterile tray via Bluetooth, synchronizing the day's medication tasks and patient information.

[0054] Next, medication verification and information entry are performed: Scanning for traceability. After removing medication from the medicine cabinet, the traceability code on the medication packaging is scanned using the multimodal scanning module 2 located on the edge of the cabinet 1 within the intelligent sterile treatment tray management system. The operator's information is also recorded. The information obtained by the multimodal scanning module 2 is transmitted to the control processing module and displayed on the mobile terminal application for easy verification of consistency with the doctor's instructions. This information includes the medication name, batch number, expiration date, manufacturer, and distribution path (traceability data).

[0055] An audible and visual alarm is provided on the outside of the cabinet 1 to realize intelligent reminder of the expiration date. If the expiration date of the medicine is ≤7 days, the audible and visual alarm will give a short beep and push a pop-up warning to the mobile terminal application, requiring the medicine to be replaced.

[0056] After scanning, the drug information is linked to the patient's medical record, and the usage time and the operating nurse's ID are recorded (to prevent errors and traceability).

[0057] Then, the sterile operation platform is set up. That is, the nurse opens the door of cabinet 1 according to the sterile operation specifications, and the internal ultraviolet lamp is automatically turned off (to avoid ultraviolet exposure); the sterile tray is partitioned, and the instrument placement area is expanded by touching the button to place medicines and instruments. After the cabinet 1 is closed, the ultraviolet lamp is automatically turned on to open the sterile barrier.

[0058] A sensor is installed in the cabinet 1 to monitor the temperature and humidity in the test tray in real time. If the environment does not meet the sterility requirements (such as too high humidity), the application will send a reminder.

[0059] Expiration date reminder after drug configuration: After the configuration of drugs and equipment is completed, confirm it on the application side, and then the application will send instructions to the control processing module to count down to the expiration date. When the warning time is reached, the sound and light alarm will be activated to alarm, and a pop-up window will be pushed through the application to warn the user.

[0060] During the medication dispensing and use process, the mobile terminal application provides operation assistance prompts. For example, when a nurse is dispensing medication, the mobile terminal application displays the recommended ratio and incompatibility warnings (such as conflicts with other medications for the patient) based on the medication type. It also supports repeated scanning: when adding new medications midway, rescanning instantly updates the medication list.

[0061] Post-processing and data archiving

[0062] Contamination Prevention: After use, place contaminated instruments in a designated recycling bin, close the sterile tray management cabinet 1, and activate the built-in UV disinfection program (the disinfection program and disinfection countdown can be set on the mobile terminal app). Light energy charging automatically starts to replenish the power consumed by the disinfection program.

[0063] Data synchronization and recording: Bluetooth automatically uploads operation logs to the hospital system, including drug batch number, time of use, and operator, forming a complete electronic traceability chain. Medical staff can export operation records with one click through the mobile terminal application for handovers or quality control inspections.

[0064] Emergency warning: If expired medicine is accidentally scanned, the sterile tray will beep and a red pop-up window will appear on the APP, forcing the user to suspend use.

[0065] Energy-saving design: In cloudy conditions, the backup battery can maintain basic functions (scanning, Bluetooth) for 72 hours.

[0066] Multi-role collaboration: Medical staff can remotely review the scan information of high-risk drugs through the APP to ensure double verification.

[0067] By integrating IoT technology with aseptic operation standards, this smart sterile tray becomes a "digital assistant" for nurses, balancing safety and efficiency. This solution reduces human error, and scan-to-source traceability and expiration date reminders lower the risk of medication errors. Automatically recording instead of handwritten records saves nurses 30% of their time, improving efficiency. It also provides closed-loop management of medications and equipment, meeting international certification standards such as JCI, and ensuring the prevention and control of nosocomial infections.

[0068] The method flow of the intelligent sterile treatment tray management method based on the Internet of Things in this application is as follows: Figure 3 As shown, the method steps include: when placing unconfigured medicines into the sterile treatment tray, the multimodal scanning module 2 scans the medicines and medical staff information; when placing configured medicines, the multimodal scanning module 2 scans the medical staff information and enters the preset warning time into the mobile terminal; when managing medicines, the environmental monitoring module 3 monitors the environmental information in real time, and the control processing module calculates and determines the expiration date of the medicines in real time on the one hand, and monitors whether the environmental information does not meet the preset ideal environment on the other hand; when the alarm situation is reached, the control module and the alarm module jointly issue an alarm.

[0069] In summary, this solution integrates Internet of Things technology and aseptic operation specifications by jointly applying a multimodal scanning module 2, an environmental monitoring module 3, a control processing module and an alarm module, and a disinfection device 4 is provided inside the cabinet 1, so as to digitize the management process of sterile trays and the medicines carried thereon. Through this solution, a disinfection environment can be provided for temporary storage of sterile treatment trays and preparation of medicines, and human errors can also be reduced. Scanning code traceability + expiration date reminder reduces the risk of medication errors, taking into account both safety and work efficiency.

[0070] Example 2

[0071] In this embodiment, a warehouse body is used instead of the cabinet body 1 as the carrier body to form an intelligent sterile treatment tray management system based on the Internet of Things. Figure 3 As shown, it includes a warehouse body, a multimodal scanning module 2, an environmental monitoring module 3, a control processing module and an alarm module. A disinfection device 4 is provided inside the warehouse body; the multimodal scanning module 2 is provided on the outside of the cabinet body 1 for scanning drug information and medical staff information; the environmental monitoring module 3 is provided inside the cabinet body 1 for real-time monitoring of the environment inside the cabinet; the control processing module is connected to the environmental monitoring module 3, the multimodal scanning module 2 and the alarm module, and the control processing module is wirelessly connected to the mobile terminal; the control processing module is used to store and process the information obtained by the multimodal scanning module 2 and the environmental monitoring module 3, and to jointly issue an alarm with the alarm module when an alarm is required; the alarm module is used to issue an alarm after receiving the alarm signal from the control processing module; in this embodiment, as shown in FIG. Figure 4 As shown, the photovoltaic panel 5 is arranged on the upper surface of the warehouse body, which can fully utilize the light energy. The remaining structural features of the system are the same as those of Example 1.

[0072] In this embodiment, a warehouse body is used instead of the cabinet body 1 as the carrying body, so that the system has the characteristics of portability and flexibility; the warehouse body is light and can be carried with one hand or easily placed on a cart or tray. It is suitable for medical staff to quickly obtain supplies in narrow wards, bedside first aid and other scenarios. It is especially suitable for medical scenarios that require immediate response, such as emergency surgery and bedside treatment of critically ill patients. Compared with the large cabinet body 1, it can significantly shorten the time to obtain supplies.

[0073] In summary, this system is widely applicable to a variety of carriers, and can realize the intelligent management of medical supplies such as sterile treatment trays and medicines, effectively improving the storage safety, operation standardization and management efficiency of medical supplies, and meeting the needs of information and automated management of materials in different medical scenarios.
