Description

Technical Field

[0001] This invention relates to the field of intelligent medical device management technology, and in particular to a medical device full-cycle management system based on a hospital HIS system, its application method, electronic equipment, and computer-readable storage medium. Background Technology

[0002] Medical device management is an indispensable part of the modern healthcare system, its importance manifesting in multiple aspects, while traditional management methods also have significant limitations. These will be elaborated upon below:

[0003] I. The Necessity of Medical Device Management

[0004] 1. Ensuring patient safety and quality of care:

[0005] Avoiding harm: This is the most fundamental reason. Medical devices (whether simple cotton swabs or complex life support equipment) act directly or indirectly on the human body. Ineffective, damaged, unsterilized, expired, misused, or uncalibrated devices are highly likely to cause harm or even death to patients (such as surgical instrument malfunction, infection control failure, diagnostic equipment errors leading to misdiagnosis, and treatment equipment malfunction).

[0006] Ensuring effectiveness: Equipment can only achieve its intended diagnostic or therapeutic effect when it is fully functional, performs accurately, and is used and maintained correctly. Effective management ensures that equipment is in a usable and reliable state, supporting physicians in making accurate judgments and providing effective treatment.

[0007] Preventing cross-infection: Strictly managing the cleaning, disinfection, and sterilization processes of reusable instruments is a key aspect of preventing nosocomial infections.

[0008] 2. Compliance and legal requirements:

[0009] Countries and regions worldwide (such as China's "Regulations for the Supervision and Administration of Medical Devices," the US FDA regulations, and the EU's MDR / IVDR) have strict laws and regulations that impose mandatory requirements on the entire lifecycle management of medical devices. Medical institutions and manufacturers must comply with these regulations, or they will face serious consequences such as legal action, hefty fines, and license revocation.

[0010] 3. Cost control and economic operation:

[0011] Avoiding waste: Medical devices are often a significant source of capital investment and operating costs for hospitals (procurement, maintenance, consumables). Effective management can precisely control inventory (avoiding expiration, stockpiling, or shortages), optimize procurement plans (based on actual needs and equipment lifespan), and reduce waste caused by equipment idleness, unplanned downtime, and duplicate purchases.

[0012] Extend service life: Scientific preventive maintenance and timely repair can significantly extend the service life of equipment, thereby reducing the frequency of replacement and amortizing investment costs.

[0013] Reduce maintenance costs: Regular maintenance and calibration can reduce the risk of sudden failures and major overhauls, thereby reducing subsequent maintenance costs and revenue loss due to downtime.

[0014] Improve operational efficiency: Ensure equipment availability, reduce delays in examinations and treatments or suspensions of surgery due to equipment failure, and improve the efficiency and accessibility of clinical departments and services.

[0015] 4. Risk Management and Liability Reduction:

[0016] By establishing standardized processes (such as equipment acceptance, calibration, maintenance, and operation training records) and maintaining complete records, it is possible to clearly trace the equipment status and operational responsibility, conduct effective investigations and determine responsibility in the event of adverse events or accidents, and protect medical personnel and institutions from unnecessary litigation and legal risks.

[0017] Improving clinical work efficiency and experience:

[0018] Quickly locate the required equipment and reduce search time.

[0019] Reduce workflow interruptions caused by equipment failure, lack of consumables, or lack of operators.

[0020] Standardized operating and maintenance procedures reduce the management burden on clinical staff.

[0021] Supporting evidence-based decision-making:

[0022] By recording data on equipment operation, failures, maintenance, and usage costs, we can provide objective data-driven support for future procurement decisions (such as equipment selection and brand evaluation), budget formulation, and resource allocation.

[0023] II. Traditional Medical Device Management Methods

[0024] Before the support of modern information systems, medical device management mainly relied on manual operation and paper records, with the following key characteristics:

[0025] 1. Procurement and Acceptance:

[0026] The department fills out the purchase requisition form by hand, which then goes through various levels of approval.

[0027] It relies on purchasing staff to manually record supplier information and contract terms.

[0028] After the new equipment arrives, information such as model number, serial number, purchase date, and price is manually recorded in paper ledgers or simple spreadsheets (such as Excel). These records are then stored in glass or metal cabinets, which are prone to rusting.

[0029] The user department, the medical engineering department, and the supplier conduct manual acceptance tests and sign paper documents.

[0030] There is a lack of overall planning and budget control for the entire life cycle cost of equipment.

[0031] 2. Ledger and Inventory Management:

[0032] Main tools: paper cards, binders, or simple Excel spreadsheets.

[0033] Information is scattered: Information about the same equipment (basic information, maintenance records, usage records, metering information) may be scattered across different departments and different administrators in different notebooks or forms.

[0034] Poor real-time performance: Changes in equipment status (such as borrowing, transfer, repair, or scrapping) rely on manual records and verbal / telephone communication, which can easily lead to delays or forgetting.

[0035] Inventory counting is difficult: regular inventory counts rely on a lot of manpower, are time-consuming and labor-intensive, and are prone to errors. Discrepancies between the records and the actual inventory are a common problem.

[0036] Inefficient consumables management: High-value consumables typically rely on manual issuance records by warehouse staff, lacking detailed tracking (especially for implants). Low-value consumables rely on experience-based inventory estimations, often resulting in expired or short-supply items.

[0037] Location difficulties: Finding the location of a specific device requires making a phone call or running errands.

[0038] 3. Maintenance and Measurement:

[0039] Relying on schedules and manual memory: Preventive maintenance plans written on paper schedules or calendar reminders are easily overlooked.

[0040] Slow repair response: Fault reporting usually requires users to fill out a paper repair form or make a phone call, which is inefficient and information transmission is prone to distortion.

[0041] Fragmented records: Historical and measurement information is maintained on separate paper worksheets, making it difficult to summarize and analyze.

[0042] Lack of data-driven decision-making: It is difficult to systematically analyze equipment failure modes, maintenance costs, and performance degradation trends, making it difficult to make scientific replacement decisions.

[0043] Metrological traceability is difficult: calibration records are manually registered, and there is a high risk of using them beyond their expiration date.

[0044] Training and Use:

[0045] Operational training relies on experienced staff mentoring new employees or ad-hoc group lectures, lacking standardized training materials (especially complex manuals which are difficult to find) and records.

[0046] It is difficult to supervise the operation procedures and their implementation.

[0047] Disposal:

[0048] The scrapping process lacks standardized procedures and transparent records, asset disposal information may be lost, and asset accounts may not be adjusted in a timely manner.

[0049] General questions:

[0050] Information silos: Information cannot be shared between different stages, resulting in high communication costs and low collaboration efficiency.

[0051] Over-reliance on personal experience: Managerial effectiveness depends heavily on the manager's sense of responsibility and memory.

[0052] Error-prone: Manual recording and input inevitably introduce errors.

[0053] Lack of early warning: There is a lack of automatic reminders for changes in equipment status (expiration, maintenance required, metering overdue), inventory thresholds, etc.

[0054] Difficulties in querying and statistics: Generating reports is laborious, making it difficult to conduct big data analysis and provide comprehensive support for management decisions.

[0055] Therefore, medical device management is a core guarantee system in the modern medical system, concerning life safety, compliant operation, economic efficiency, and service quality. Its necessity is irreplaceable. However, traditional management methods relying on manual and paper-and-pen methods have revealed significant limitations in the face of increasingly sophisticated equipment, a surge in quantity, increasingly stringent regulations, and higher demands for efficiency and cost control. These limitations include inefficiency, information silos, insufficient data value mining, weak risk warning capabilities, and difficulties in process collaboration. This is the fundamental reason why modern Medical Device Management Information Systems (CMMS) or more advanced Asset Performance Management Systems (APM) have become the inevitable choice for industry upgrades—they are committed to achieving standardized, refined, information-based, and intelligent device management.

[0084] Preferably, the instrument storage cabinet further includes:

[0085] The employee badge reader interacts with the user's employee badge, obtains user information, and sends the user information to the microserver via the MCU. The microserver then reports the information to the hospital's HIS system, which identifies and verifies the user information.

[0086] If the verification is successful, the corresponding permission unlocking command is sent to the microserver of the corresponding instrument storage cabinet, and the microserver unlocks the application control permission of the current instrument storage cabinet for the user.

[0087] If the verification fails, a corresponding unlocking failure command will be sent to the PC / APP terminal;

[0088] The employee badge reader is electrically connected to the MCU.

[0089] On the other hand, an application method for a medical device full-cycle management system based on a hospital HIS system is provided, the application method including the following steps:

[0090] Users can log in to the HIS system via PC / APP, verify their user information, and then enter the name and quantity of the medical devices to be removed.

[0091] The HIS system performs a database search based on the input name and quantity of the medical devices to be retrieved, and determines whether the medical device storage forms of each of the device storage cabinets match the name and quantity of the medical devices to be retrieved.

[0092] If the conditions are not met, a replenishment strategy for the corresponding medical device will be generated and sent to the corresponding user's PC / APP.

[0093] If the conditions are met, the medical device storage form of each of the device storage cabinets is matched with the name and quantity of the medical devices to be retrieved. The device storage cabinet that matches the name and quantity of the medical devices to be retrieved is found, and an unlocking command for the corresponding device storage cabinet is generated. The unlocking command is sent to the microserver, which executes the unlocking command for the corresponding device storage cabinet and controls the MCU of the corresponding device storage cabinet to open its electromagnetic lock. After opening, the system waits for the user to retrieve the medical devices to be retrieved.

[0094] When a user retrieves a medical device, the device storage cabinet senses the weight of the device being stored or retrieved and sends this signal to the MCU. The MCU calculates the weight of the device and sends it to the microserver, which then reports it to the hospital's HIS system. The HIS system compares the weight of the device with the previously recorded medical device storage form, identifies the device information, updates the previously recorded form, and obtains the current medical device storage form.

[0096] Users swipe their work badges to interact with the corresponding work badge reader on the medical device storage cabinet. The work badge reader acquires user information and sends it to the microserver via the MCU. The microserver then reports the information to the hospital's HIS system, which identifies and verifies the user information.

[0097] If the verification is successful, the corresponding permission unlocking command is sent to the microserver of the corresponding medical device storage cabinet. The microserver then unlocks the application control permission of the current medical device storage cabinet for the user. The user inputs the name and model of the medical device to be retrieved through the control board of the corresponding medical device storage cabinet, and the MCU of the corresponding medical device storage cabinet opens its electromagnetic lock. After opening, it waits for the user to retrieve the medical device to be retrieved.

[0098] If the verification fails, a corresponding unlocking failure command will be sent to the PC / APP terminal;

[0099] When a user retrieves a medical device, the device storage cabinet senses the weight of the device being stored or retrieved and sends this signal to the MCU. The MCU calculates the weight of the device and sends it to the microserver, which then reports it to the hospital's HIS system. The HIS system compares the weight of the device with the previously recorded medical device storage form, identifies the device information, updates the previously recorded form, and obtains the current medical device storage form.

[0100] On the other hand, an electronic device is provided, comprising: a processor; and a memory storing computer-readable instructions, wherein when the computer-readable instructions are executed by the processor, the application method of the medical device full-cycle management system based on the hospital HIS system described above is implemented.

Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in embodiments of the present invention, the meaning expressed by "and / or" can be both, or either one.

[0111] In the embodiments of this invention, the terms "image" and "picture" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning. Similarly, the terms "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning.

[0112] In this embodiment of the invention, sometimes a subscript such as W1 may be mistakenly written as a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0113] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0114] This invention provides a device lifecycle management system and method based on a hospital HIS system. This method can be implemented using electronic devices, which can be terminals or servers. Figure 1 The diagram shown illustrates the composition of a hospital HIS-based medical device lifecycle management system. The system includes:

[0115] Several instrument storage cabinets are used to store corresponding types of medical devices;

[0116] The microserver is used to manage each of the medical device storage cabinets, report the medical device access information in each of the medical device storage cabinets to the hospital server; and / or respond to the medical device management instructions issued by the hospital server, and control the corresponding medical device storage cabinet to perform corresponding medical device management actions.

[0117] The hospital server is used to inventory and record the access information of medical devices in each of the device storage cabinets through the deployed HIS system, so as to realize the full life cycle management of the medical devices.

[0118] Each of the aforementioned instrument storage cabinets is communicatively connected to the microserver;

[0119] The microserver is communicatively connected to the hospital server.

[0120] In this embodiment, the function and structure of the medical device storage cabinet can refer to the application principle of existing smart lockers (such as Fengchao lockers, each of which has an electromagnetic lock that will pop open the control door after unlocking, and each of which has a microserver to drive and control several sub-units / small cabinets). However, this invention uses it for the intelligent storage of medical devices and interfaces with the hospital HIS system to realize the HIS system management of medical devices.

[0121] When medical devices are being inventoried and put into storage, information about the medical devices in each storage cabinet can be recorded and saved in advance through the HIS system, such as the time of entry, the person entering the storage, the name, the model and the quantity.

[0122] The specific types and quantities of medical devices stored in each equipment storage cabinet can be configured by the hospital warehouse manager based on regulations or demand orders for the current day and the next few days. For example, the configuration of corresponding medical device packages can be increased or decreased based on the difference between the medical device package usage in the HIS system and the department's existing reserves.

[0123] If necessary, identify and record the department / outpatient information of the equipment to be needed, including the name, model, quantity, time, etc. of the equipment to be needed. Then, collect this information and notify the warehouse manager to configure the corresponding "equipment storage cabinets". Record the medical device storage form (configuration form of the medical devices stored in the equipment storage cabinets) of these configured equipment storage cabinets in the HIS system.

[0124] If not, proceed to the next page.

[0125] The application process of this system will be described in detail below.

[0126] like Figure 2 As shown, preferably, the instrument storage cabinet includes:

[0127] MCU is used for logic control and calculation.

[0128] An electromagnetic lock is used to lock the instrument storage cabinet.

[0129] A sensor is used to sense the weight of the medical device being stored in or retrieved from the instrument storage cabinet and feed it back to the MCU. The MCU calculates the weight of the medical device being stored or retrieved based on the weight sensing signal and sends it to the microserver, which then reports it to the hospital's HIS system. The HIS system compares and analyzes the weight of the medical device being stored or retrieved based on the previously recorded medical device storage form of the instrument storage cabinet (which records the weight of each stored medical device; since almost all different types of medical devices have different sizes and materials, devices with the same weight are not considered). It identifies the information of the medical device being stored or retrieved and updates the previously recorded medical device storage form to obtain the current recorded medical device storage form of the instrument storage cabinet.

[0130] A display screen is used to show the medical device storage list of the instrument storage cabinet;

[0131] A communication port is provided for the instrument storage cabinet to communicate with the microserver.

[0132] The control panel is used to input access commands for the corresponding medical devices.

[0133] Power supply, used for supplying power;

[0134] The electromagnetic lock, display screen, sensor, communication port, control board, and power supply are all electrically connected to the MCU.

[0135] Preferably, the medical device information includes at least one of the following:

[0136] The name and model of the medical device being accessed;

[0137] The access time of the medical devices being accessed;

[0138] The person who deposited or retrieved the medical device;

[0139] or

[0140] The number of medical devices stored or retrieved.

[0141] Preferably, the number of the medical devices includes:

[0142] The updated current quantity of each medical device in the aforementioned instrument storage cabinet;

[0143] The total number of all medical devices in the instrument storage cabinet mentioned at the time of admission.

[0144] like Figure 3 As shown, preferably, the display screen includes:

[0145] The first display screen is used to display the name and model of the accessed medical device based on a green LED backlight;

[0146] The second display screen is used to show the number of accessed medical devices based on a red LED backlight.

[0147] Preferably, the instrument storage cabinet further includes:

[0148] The employee badge reader interacts with the user's employee badge, obtains user information, and sends the user information to the microserver via the MCU. The microserver then reports the information to the hospital's HIS system, which identifies and verifies the user information.

[0149] If the verification is successful, the corresponding permission unlocking command is sent to the microserver of the corresponding instrument storage cabinet, and the microserver unlocks the application control permission of the current instrument storage cabinet for the user.

[0150] If the verification fails, a corresponding unlocking failure command will be sent to the PC / APP terminal;

[0151] The employee badge reader is electrically connected to the MCU.

[0152] This embodiment provides an example of hardware configuration for a medical device lifecycle management system based on a HIS system, as shown in Table 1 below:

[0154] Table 1

[0155] Specific applications are as follows:

[0156] I. System Architecture Design

[0157] 1.1 Overall Architecture

[0158] The system adopts a three-tier architecture: terminal layer - middleware layer - platform layer.

[0159] Terminal layer: The instrument storage cabinet integrates an MCU controller, a high-precision weight sensor (error ±0.1g), a dual-color LED display (green for model / red for quantity), and a work badge reader. It communicates with the microserver via an RS-485 bus. The instrument storage cabinet monitors storage and retrieval operations in real time through the weight sensor. The MCU calculates the weight difference and transmits it to the microserver. The dual-color LED screen displays the instrument model (green) and quantity (red) in categories. The work badge reader verifies access.

[0160] Middle layer: The microserver deploys edge computing modules to process the weight data reported by each cabinet in real time and interacts with the hospital HIS system via HTTPS protocol, supporting bidirectional command transmission (such as emergency locking commands); the microserver aggregates the data from each cabinet and synchronizes it to the hospital HIS system, while executing reverse control commands (such as unlocking electromagnetic locks), forming a bidirectional communication link;

[0161] Platform Layer: The HIS system extends the medical device management module, establishing an SQL database containing medical device names, models, and lifecycle status. Dynamic inventory updates are achieved through a weight change correlation algorithm. The HIS system dynamically updates medical device inventory status by comparing historical data with current weight data, generating an electronic ledger containing comprehensive information such as medical device name, access time, and operator, supporting hospital-wide traceability analysis.

[0162] 1.2 Hardware Design

[0163] Sensor Network: Each cabinet is equipped with 4-point weighing sensors (the specific configuration and installation method are set according to the placement of the items in the cabinet, mainly the bottom, sides, etc. where sensors need to be installed. For example, suspended instruments can be monitored by tension sensors; flat instruments can be monitored by pressure / weight sensors installed at the bottom of the cabinet). The MCU uses Kalman filtering to eliminate environmental vibration interference and extract the effective weight signal.

[0164] Access control: The employee badge reader supports RFID / NFC dual-mode recognition, and the HIS system verifies the user's department permissions in real time and records the operation log;

[0165] Human-computer interaction: The control panel adopts an anti-accidental touch design, and the dual-screen display distinguishes between instrument attributes (green screen) and real-time inventory (red screen).

[0166] For specific configuration details, please refer to Table 1 above.

[0167] II. Working Principle

[0168] 2.1 Instrument Storage and Retrieval Procedure

[0169] Authentication: After the user swipes their card, the HIS system compares the data with the authorization database, and the microserver receives the unlock command and activates the electromagnetic lock.

[0170] Weight detection: The storage and retrieval operation triggers the sensor signal, the MCU calculates the weight difference and converts it into standard instrument units (e.g., 1 surgical forceps ≈ 15g).

[0171] Data synchronization: The microserver compresses and transmits data to the HIS system, which then updates the inventory form after verifying the data integrity using a hash algorithm;

[0172] Anomaly Handling: When unauthorized access is detected (e.g., weight reduction but no card swipe record), trigger the cabinet's audible and visual alarm and freeze the operation permissions.

[0173] 2.2 Full Lifecycle Management Logic

[0174] Inbound stage: Scan the UDI code of the instrument and bind it to the electronic file; the HIS system allocates storage cabinet space and initializes the weight reference value.

[0175] During the requisition phase: The system automatically links the medical device package in the HIS system and verifies the matching between the requisitioned quantity and the remaining inventory;

[0176] Maintenance phase: Maintenance reminders are triggered based on the number of times the equipment is used (number of weight changes) and pushed to the equipment department's work order system;

[0177] Scrapping phase: Equipment that has exceeded its service life or is faulty is marked by the HIS system, and the asset write-off process is initiated simultaneously by the financial system.

[0178] The above solution can achieve the following technical implementation effects:

[0179] 1. Improved management efficiency

[0180] Inventory accuracy: Dynamic weighing technology reduces inventory counting errors from 8% with manual operations to 0.3%;

[0181] Response speed: Emergency equipment requisition time has been reduced from 15 minutes to 2 minutes (authorization verification + automatic warehousing).

[0182] Cost control: By reducing over-procurement by 30% through lifespan prediction, annual consumable expenditures are saved by approximately 120,000 yuan (sample from a tertiary hospital).

[0183] 2. Safety and Compliance

[0184] Traceability: The complete usage chain of any device can be traced, including the operator, time, and related patient medical records;

[0185] Access control: A tiered authorization system (medical staff / equipment department / administrators) reduces the risk of medical device misuse;

[0186] Audit compliance: Complies with the electronic ledger requirements of the "Regulations on Supervision and Management of the Quality of Medical Device Use".

[0187] This solution can also utilize AI prediction: An LSTM model is trained based on historical data to predict the consumption trend of medical devices over the next three months; this is combined with big data on medical device consumption from the HIS system as training data for model training, thereby predicting future monthly consumption trends and allowing for advance notification for stockpiling. Specifically, an LSTM-based AI prediction model for medical device consumption can be developed and deployed on a hospital server, combining the LSTM model with the big data on medical device consumption from the HIS system. Model training can follow the traditional training methods for LSTM models, which will not be elaborated upon here.

[0188] Based on the above system functions, the present invention also provides the following two methods for obtaining medical devices:

[0189] Case 1: Employees log into the HIS system, enter the name and quantity of the medical devices they need, and the corresponding storage cabinet pops up. The backend records the retrieval time and date, the person who retrieved the device, and the name and quantity of the device retrieved. Specifically, the following provides an application method for a full-cycle medical device management system based on a hospital HIS system, which includes the following steps:

[0190] Users can log in to the HIS system via PC / APP, verify their user information, and then enter the name and quantity of the medical devices to be removed.

[0191] The HIS system performs a database search based on the name and quantity of the medical devices to be retrieved, and determines whether the medical device storage forms of each of the device storage cabinets match the name and quantity of the medical devices to be retrieved.

[0192] If the conditions are not met, a replenishment strategy for the corresponding medical device will be generated and sent to the corresponding user's PC / APP.

[0193] If the conditions are met, the medical device storage form of each of the device storage cabinets is matched with the name and quantity of the medical devices to be retrieved. The device storage cabinet that matches the name and quantity of the medical devices to be retrieved is found, and an unlocking command for the corresponding device storage cabinet is generated. The unlocking command is sent to the microserver, which executes the unlocking command for the corresponding device storage cabinet and controls the MCU of the corresponding device storage cabinet to open its electromagnetic lock. After opening, the system waits for the user to retrieve the medical devices to be retrieved.

[0194] When a user retrieves a medical device, the device storage cabinet senses the weight of the device being stored or retrieved and sends this signal to the MCU. The MCU calculates the weight of the device and sends it to the microserver, which then reports it to the hospital's HIS system. The HIS system compares the weight of the device with the previously recorded medical device storage form, identifies the device information, updates the previously recorded form, and obtains the current medical device storage form.

[0195] Case 2: A staff member swipes their badge on the side of the instrument storage cabinet to unlock the interface. Based on the name and number on the cabinet, the user inputs the name of the cabinet door to be opened. After the door opens, the instrument is retrieved. The cabinet records the number of instruments taken based on the weight difference before and after retrieval. Specifically, the following provides an application method for a full-cycle instrument management system based on a hospital HIS system. The application method includes the following steps:

[0196] Users swipe their work badges to interact with the corresponding work badge reader on the medical device storage cabinet. The work badge reader acquires user information and sends it to the microserver via the MCU. The microserver then reports the information to the hospital's HIS system, which identifies and verifies the user information.

[0197] If the verification is successful, the corresponding permission unlocking command is sent to the microserver of the corresponding medical device storage cabinet. The microserver then unlocks the application control permission of the current medical device storage cabinet for the user. The user inputs the name and model of the medical device to be retrieved through the control board of the corresponding medical device storage cabinet, and the MCU of the corresponding medical device storage cabinet opens its electromagnetic lock. After opening, it waits for the user to retrieve the medical device to be retrieved.

[0198] If the verification fails, a corresponding unlocking failure command will be sent to the PC / APP terminal;

[0199] When a user retrieves a medical device, the device storage cabinet senses the weight of the device being stored or retrieved and sends this signal to the MCU. The MCU calculates the weight of the device and sends it to the microserver, which then reports it to the hospital's HIS system. The HIS system compares the weight of the device with the previously recorded medical device storage form, identifies the device information, updates the previously recorded form, and obtains the current medical device storage form.
