Description

Operating Room Intelligent Shoe Changing System Technical Field

[0001] This invention belongs to the field of operating room environment maintenance and management technology, and particularly relates to an intelligent shoe changing system for operating rooms. Background Technology

[0002] Operating room environment maintenance and management is fundamental to hospital infection control, directly impacting surgical success rates and patient safety. Medical staff must change clothes and shoes upon entering the operating room. Traditionally, this was done manually using ordinary storage cabinets. Since 2017, an information-based management system has been implemented, relying on information technology for semi-automated management, primarily addressing the automated distribution of clothing and shoes. The shoe changing cabinets still utilize electronic storage units. However, electronic storage units have several drawbacks: First, they waste building space. Currently, the fixed cabinet height is less than 2.0m, resulting in significant wasted space above the cabinets. The spacing between cabinets is at least 0.9m, and multiple rows occupy a large area. Second, the cabinets need clear identification numbers; for large orders, random allocation is used, requiring users to find and remember the cabinet locations. Third, the cleaning and disinfection of each cabinet entrance remains unresolved, relying mainly on regular manual cleaning, which struggles to meet basic infection control requirements.

[0003] Existing smart lockers are used in areas such as express delivery, public places, and unmanned retail, and are technologically advanced using the Internet of Things, mobile payment, and biometrics. However, simple storage methods cannot meet the infection control and isolation requirements of medical institutions.

[0004] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0005] Wasteful use of building space: the current fixed height of the cabinets is less than 2.0m, resulting in a huge waste of space above the cabinets. The distance between cabinets is at least 0.9m, and multiple rows of cabinets occupy a large area.

[0006] The cabinets need to be clearly labeled with specific cabinet numbers. If there is a large demand, they will be randomly assigned. Users need to find and remember the location of the cabinets.

[0007] The cleaning and disinfection of each cabinet entrance cannot be resolved, and the main reliance is on regular manual cleaning, which makes it difficult to guarantee the basic requirements for hospital infection control. Summary of the Invention

[0008] To address the problems existing in the prior art, the present invention provides an intelligent shoe changing system for operating rooms.

[0009] This invention is implemented as follows: an intelligent shoe-changing system for operating rooms includes:

[0010] The identity recognition module, including a biometric acquisition device and an identity recognition processing unit, is used to collect and process facial images or other biometric information of medical personnel and output the identity recognition results to the main control module.

[0011] The camera module includes an image sensing device and an image processing unit, used to capture footwear image information when a person takes off their shoes, and upload the image data to the main control module for image matching and archiving;

[0012] The main control module, including a processor, memory and built-in control program, communicates with the identity recognition module, photo capture module, transmission module, information binding module and storage module through a data bus. It is used to receive the raw data collected by each module, perform centralized processing, logical judgment and issue control commands.

[0013] The conveying module, including a conveyor belt drive, a position encoder, and a status detection unit, is used to automatically transfer the shoes from the shooting area to the designated shoe box according to the control commands issued by the main control module, and to transmit the running status signal back in real time.

[0014] The information binding module includes a shoebox information collection device and a binding control unit, which is used to collect shoebox ID or location information, bind the information to the personnel identity one by one, and transmit it synchronously to the main control module for recording and management;

[0015] The storage module includes a cabinet and multiple independently identifiable shoe storage boxes installed inside the cabinet. The cabinet can be arranged in columns, rows or vertically. Each shoe storage box can receive shoes from the conveying module and provide feedback on the placement status information.

[0016] The communication mechanism involves data transmission and command interaction between the modules based on standardized communication protocols (including but not limited to UART, CAN, RS485, or TCP / IP) to ensure coordinated operation and real-time response of the system modules.

[0017] Furthermore, the identity recognition module includes: a display and a biometric device;

[0018] A display screen used to show identification information;

[0019] Biometrics are used to identify personal information.

[0020] Furthermore, the storage module includes: a cabinet and a shoe storage box.

[0021] Another object of the present invention is to provide an intelligent shoe changing method in the operating room, comprising:

[0022] Step 1: Identify the user through the identity recognition module;

[0023] Step 2: Take off your shoes using the camera module and take a photo at the display area on the counter.

[0024] Step 3: The shoes are transported via conveyor belt through the main control module and the transmission module.

[0025] Step 4: Bind shoe box information through the information binding module;

[0026] Step 5: Use the storage module to store the shoes in the cabinet.

[0027] Another object of the present invention is to provide a computer device including a memory and a processor, the memory storing a computer program, which, when executed by the processor, causes the processor to perform the steps of the intelligent shoe-changing method in the operating room.

[0028] Another object of the present invention is to provide a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the steps of the intelligent shoe-changing method in the operating room.

[0029] Another objective of this invention is to provide an information data processing terminal for implementing the intelligent shoe-changing system in the operating room.

[0030] This invention provides an integrated intelligent shoe changing system. Its core lies in the linkage between a personnel identification system and a shoe storage and retrieval control system to achieve automatic placement and retrieval of shoes. The entire process is completed in the same cabinet without manual intervention or manually searching for the shoe cabinet entrance, which greatly improves operational efficiency and standardized management.

[0031] The system automatically binds the corresponding storage location based on the medical staff's identity information (such as employee number, facial recognition, etc.), and accurately delivers the shoes to the designated area of ​​the cabinet through the built-in transmission and positioning module. The entire storage and retrieval process is closed, efficient, and contactless, meeting the process control and infection control requirements of the hospital's clean area.

[0032] This invention adopts a front-facing doorless design, with the shoe cabinet opening uniformly located at one end of the internal conveying system. The system controls the shoe entry and exit channel, avoiding the visual confusion and operational inconvenience caused by traditional multi-door structures, further optimizing the human-computer interaction experience of the shoe changing process, and improving the overall intelligence level of the system.

[0033] The intelligent shoe-changing system is particularly suitable for hospital settings with high requirements for aseptic control and personnel behavior management, including critical areas such as operating rooms, interventional catheterization rooms, endoscopy rooms, supply centers, ICUs, and hemodialysis centers. It is especially suitable for renovation projects with limited traditional space and restricted shoe-changing area settings, and has good system compatibility and installation flexibility.

[0034] The main structure of the shoe cabinet can extend from the ground to the ceiling, maximizing the use of vertical space. With the same floor area, its shoe storage capacity can be increased to 3 to 4 times that of the traditional structure, significantly alleviating the problem of insufficient storage caused by high personnel density and enhancing the functionality of the hospital changing area.

[0035] The interior of the cabinet features a continuous, open, and partition-free structure, preventing the formation of hard-to-clean corners and significantly reducing the burden of cleaning and maintenance. At the same time, the shoe-changing area layout is more compact and streamlined, reducing the required space to half that of traditional solutions. The entrance requires no manual supervision, effectively improving flow efficiency and pedestrian traffic capacity. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] As shown in Figure 1, an intelligent shoe-changing system for operating rooms provided by an embodiment of the present invention includes:

[0047] Identity recognition module 1, photo taking module 2, main control module 3, transmission module 4, information binding module 5, storage module 6.

[0048] Identity recognition module 1, connected to camera module 2, is used for identity recognition;

[0049] Photo module 2, connected to main control module 3, is used to take photos at the display area of ​​the cabinet opening when shoes are removed;

[0050] The main control module 3 is connected to the photo-taking module 2, the transmission module 4, the information binding module 5, and the storage module 6, and is used to control the normal operation of each module.

[0051] Conveying module 4, connected to main control module 3, is used to convey shoes via conveyor belt;

[0052] Information binding module 5, connected to main control module 3, is used for binding shoe box information;

[0053] Storage module 6, connected to main control module 3, is used to store shoes through the cabinet.

[0054] The identity recognition module 1 collects user biometric data through integrated biometric sensors (such as iris scanners or facial recognition cameras). After noise reduction by the preprocessing module, the digitized feature data is input into the embedded recognition algorithm, which compares the sample features stored in the database in real time to achieve identity verification. The recognition results and corresponding timestamp data are then transmitted to the main control module 3.

[0055] After receiving the instruction from the main control module 3, the photo module 2 captures the image signal of the user taking off his shoes at the counter using a high-resolution image sensor. After image preprocessing (including image enhancement, background separation and ROI extraction), the processed image data is uploaded to the main control module 3 for subsequent status verification and record archiving.

[0056] As the core control unit of the system, the main control module 3 fuses the received identity recognition data and the image data output by the camera module, synchronizes the data using the real-time data acquisition bus, judges the operation status based on the preset algorithm logic, and triggers the action instructions of subsequent modules to realize data interaction and unified scheduling between modules.

[0057] Under the motion control commands issued by the main control module 3, the conveyor module 4 drives the conveyor belt motor through a PLC (Programmable Logic Controller) to start the shoebox conveying process. The encoder embedded in the module provides real-time position information, and the motion deviation is corrected through a closed-loop control algorithm to ensure the positioning accuracy and stability of the shoebox during the conveying process.

[0058] After receiving the scheduling command from the main control module 3, the information binding module 5 collects shoebox information through the integrated barcode / RFID reader and binds it with user identity information, timestamp, and system operation number to form a unique digital identifier. The bound data is then processed by an encryption algorithm and transmitted back to the main control module 3 to ensure data integrity and security.

[0059] Under the command of the main control module 3, the storage module 6 starts the electromagnetic drive or stepper motor to perform the shoebox storage action. At the same time, it uses position sensors to monitor the storage position in real time, completing the automatic storage of the shoebox. After the storage operation is completed, this module uploads the storage success status data and abnormal alarm information to the main control module 3, and updates the system database in real time, realizing a closed loop of data recording, error detection and feedback for the entire operation process.

[0060] As shown in Figure 6, the identity recognition module provided in this embodiment of the invention includes: a display and a biometric identifier;

[0061] A display screen used to show identification information;

[0062] Biometrics are used to identify personal information.

[0066] S102, take off your shoes using the camera module and take a picture at the display screen at the counter;

[0067] S103, the main control module uses a conveyor module to transport shoes via a conveyor belt;

[0068] S104, bind shoe box information through the information binding module;

[0069] S105 uses a storage module to store shoes in a cabinet.

[0070] This invention provides an intelligent shoe-changing system and method suitable for operating room scenarios. Its core lies in achieving intelligent control of the entire process of automatic shoe identification, removal, transmission, and storage through an integrated hardware structure and multi-module collaboration, thereby optimizing the shoe-changing process for medical staff and improving the efficiency of clean area behavior management.

These products all utilize high-performance processors and edge computing technology to support real-time data acquisition, processing, and feedback, meeting the stringent requirements of hospitals for safe, accurate, and efficient management, and ensuring the complete digitalization and automation of footwear management in the operating area.

[0097] 3. This system can also be seamlessly integrated with the hospital's information management platform to form a unified data exchange and control platform, enabling intelligent linkage of identity recognition, image verification, data binding, transmission control, and storage management. High-speed data buses and standardized communication protocols are used between modules to ensure the real-time performance and reliability of data transmission between subsystems, providing key technical support for hospitals to build a safe and efficient shoe-changing environment.
