Rather, the terms "exemplary" or "for example" are intended to present the relevant concept in a specific manner.

[0074] Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor are within the scope of protection of the present application.

[0075] Hospital high-value consumables refer to medical devices that are implanted or intervened into the human body or part thereof through surgical operation and remain in the human body for more than one month after the operation. These consumables can be generally divided into artificial joint type, cardiac intervention type, anesthetic material type, etc., and can be divided into artificial lens type, blood vessel type, spring type, pacemaker type, etc. according to the application range, and other types in total 10 categories. With the development of medical technology, especially the popularization of surgical operation and interventional therapy, the demand for high-value consumables in hospitals is increasing. These high-value consumables are usually used in various complex surgical and therapeutic processes, and have high functional and technical requirements, so the cost is also relatively high.

[0076] At present, there are many challenges in the management process of high-value consumables in hospitals. Since high-value consumables are expensive and are often essential key materials in the hospital treatment process, how to effectively manage the procurement, inventory, consumption, etc. of high-value consumables to avoid excessive procurement, waste or shortage is an important problem faced by hospital management.

[0077] Therefore, the medical high-value consumable management system, method, electronic device and storage medium provided by an embodiment of the present application can significantly improve the management efficiency of medical high-value consumables, reduce errors and resource waste caused by human intervention. Through full-process digital management, comprehensive tracking from consumable warehousing to consumption, allocation and settlement is realized, ensuring the transparency and traceability of consumable use. By using a demand prediction method based on a long short-term memory network (LSTM), the future use trend of consumables can be accurately predicted, effectively avoiding the situation of inventory accumulation or shortage. In addition, combined with an economic order quantity model (EOQ) and an inventory optimization algorithm, the system can meet the demand while minimizing procurement and inventory management costs. By recording and managing the consumable use during the surgery process in real time, accurate cancellation and charging reconciliation of high-value consumables are ensured, and financial disputes caused by information asymmetry or data errors are reduced. The allocation function relies on an intelligent optimization algorithm to automatically generate an optimal allocation scheme according to the inventory of each department, preferentially using self-owned inventory, thereby improving resource utilization and shortening response time. By integrating a globally unique identifier (GUID) and a unique device identifier (UDI), the source, purpose and use state of each consumable can be quickly located, providing efficient support for hospital supervision and supplier reconciliation.

[0078] Figure 1 is a module schematic diagram of the medical high-value consumable management system provided by an embodiment of the present application, as shown in Figure 1 The medical high-value consumable management system 10 includes a high-value consumable management module 11, a follow-up surgery module 12, an inventory management and replenishment decision module 13 and a traceability and reporting module 14.

[0079] In the embodiment of the present application, the high-value consumable management module 11 is connected to the inventory management system and the medical information system of the hospital, for obtaining the unique device identifier and the globally unique identifier of the high-value consumable, and also for obtaining the traceability information of the high-value consumable according to the unique device identifier and the globally unique identifier, and storing the traceability information to the inventory management system. The high-value consumable management module 11, as the core data management unit of the system, is connected to the inventory management system and the medical information system of the hospital, and is mainly responsible for the traceability and storage of consumable data. The high-value consumable management module 11 can accurately locate the source and history of the consumable. For example, when the consumable enters the inventory, the high-value consumable management module 11 will automatically generate relevant traceability information, including the supplier, production batch and warranty period, and store the data to the inventory management system.

[0080] Specifically, the high-value consumable management module 11 can accurately locate the source and history of consumables. For example, when the consumables enter the inventory, the high-value consumable management module 11 automatically generates relevant traceability information, including the supplier, production batch, and warranty period, and stores the data to the inventory management system. In addition, the high-value consumable management module 11 can also verify the completeness and consistency of consumable data in real time. For example, if a batch of consumables is found to be defective or unqualified, the medical high-value consumable management system 10 can quickly locate and prompt the whereabouts of the relevant problem consumables, thereby reducing the safety risk.

[0081] It can be understood that the high-value consumable management module 11 is the core component of the system traceability function, which can provide transparent consumable tracking and management capabilities for hospital operations. The high-value consumable management module 11 uses data-driven methods to informatize the full life cycle management of consumables, avoiding the loopholes of manual recording and improving the accuracy and transparency of consumable tracking. This not only meets the compliance requirements of the hospital, but also provides basic support for the optimized management of consumables.

[0082] In the embodiments of the present application, the follow-up surgery module 12 is connected to the surgery management system and the high-value consumable management module of the hospital, and is used to record the consumption amount, category and use of high-value consumables used in the surgery process, and synchronize the consumption data to the inventory management system.

[0083] Specifically, before the surgery starts, the follow-up surgery module 12 will generate a list of required high-value consumables and an estimated consumption amount according to the surgery appointment sheet, and will prepare the required consumables in advance through linkage with the inventory management system. When the consumables are consumed during the surgery, the module records the use of the consumables in real time through barcode scanning or manual input, including the model, specification, quantity and specific purpose of the consumables. After the surgery is completed, the module synchronizes the use data to the inventory management system and automatically updates the consumable charging details of the patient. For example, in a cardiac intervention surgery, the system will record the use of each pacemaker, catheter or stent, and associate it with the patient's postoperative record, thereby facilitating subsequent medical traceability and reconciliation management.

[0084] It can be understood that through the follow-up surgery module 12, the system can accurately implement the management of consumables during the surgery process, reduce data recording errors and improve the efficiency of the surgery.

[0085] In the embodiments of the present application, the inventory management and replenishment decision module 13 is connected to the high-value consumable management module and the supply chain system, and is used to obtain real-time inventory information, storage cost and ordering fixed cost of high-value consumables. The inventory management and replenishment decision module 13 is also used to predict the consumption amount of high-value consumables according to the long short-term memory network, to obtain the estimated consumption amount of each high-value consumable, and to obtain the ordering amount of high-value consumables according to the economic ordering quantity model, real-time inventory information, estimated consumption amount, storage cost and ordering fixed cost.

[0086] Specifically, the inventory management and replenishment decision module 13 takes a long short-term memory network (LSTM) as the core, and outputs the demand prediction in a future time period by inputting the historical consumption data (such as daily, monthly or quarterly consumption) of high-value consumables.

[0087] It can be understood that the inventory management and replenishment decision module 13 solves the accuracy problem of consumable consumption prediction and optimizes the timing and quantity of inventory replenishment through the combination of algorithms and models. This intelligent inventory management method can significantly reduce inventory holding costs while ensuring timely satisfaction of surgical needs.

[0088] In the embodiments of the present application, the inventory management and replenishment decision module 13 is also used to: obtain historical consumption data and time characteristic variables. The historical consumption data and the time characteristic variables form an input sequence, wherein the time characteristic variables include month encoding and time step. The input sequence is input into a long short-term memory network model. The long short-term memory network model obtains monthly fluctuations through the periodic input characteristics of the monthly identifier, and outputs the estimated monthly consumption of high-value consumables.

[0089] Specifically, the inventory management and replenishment decision module 13 automatically obtains historical consumption data of various high-value consumables by interfacing with the hospital's inventory management system and surgical management system. These data include daily, monthly or quarterly usage records. At the same time, the module extracts relevant time characteristic variables, such as month encoding, quarter identifier and time step (index in time series). In the data processing stage, the module cleans and standardizes the original data to eliminate outliers and fill in missing data, thereby ensuring the accuracy and integrity of the input data. The inventory management and replenishment decision module 13 combines the cleaned historical consumption data and time characteristic variables to form a multi-dimensional input sequence. For example, for a certain cardiac intervention consumable, the input sequence may include the consumption amount in the past 12 months, the corresponding month encoding and quarter identifier, which are used to capture the time trend and periodic fluctuations of consumable demand. Through this processing, the input sequence not only retains the time correlation of consumable demand, but also reflects the consumption changes caused by monthly factors.

[0090] In the embodiments of the present application, the inventory management and replenishment decision module 13 inputs the above input sequence into a pre-trained long short-term memory network (LSTM) model. The core structure of the model includes a forget gate, an input gate and an output gate, which can effectively capture the long and short period dependencies in consumable demand. To reflect the quarterly fluctuations of consumable demand, the module adds a periodic feature of the quarter identifier to the input sequence. The model can generate more accurate prediction values reflecting monthly fluctuations by learning the correlation between the quarter identifier and the month encoding.

[0091] In actual operation, the LSTM model processes input sequences in a recursive manner, updating its internal state step by step. For example, given a sequence of monthly consumption data for a consumable over the past year: [120, 150, 140,...], and a sequence of quarterly identifiers: [1, 1, 2,...], the LSTM model updates its state and outputs using the following formula:

[0092] h t = σ(W f [h t-1 ,x t ]+b f )·h t-1 +σ(W iu [h t-1 ,x t ]+b i )·tanh(W c [h t-1 ,x t ]+b c )

[0093] where x t is the input feature, h t is the hidden state, and [W, b] are the network weights and biases. Ultimately, the model outputs a monthly consumption estimate that accurately reflects seasonal and monthly fluctuations.

[0094] It can be understood that by combining historical consumption data with time feature variables, the inventory management and replenishment decision module 13 can provide sufficient input information for the long short-term memory network model. This method significantly improves the model's prediction ability for consumable demand, making it not only adapt to long-term trends but also flexibly respond to short-term fluctuations, thereby providing a more reliable data foundation for inventory optimization. Through the dynamic learning of the long short-term memory network model, the inventory management and replenishment decision module 13 can not only accurately predict the monthly demand for consumables but also capture the impact of periodic changes on demand. This deep learning-based prediction method provides strong support for subsequent inventory and procurement decisions.

[0095] In the embodiments of the present application, the inventory management and replenishment decision module 13 is further configured to: obtain the quarterly predicted demand for each high-value consumable. Input the quarterly predicted demand into an economic order quantity model to obtain the economic order quantity. The formula of the economic order quantity model is:

[0096]

[0097] where Q is the economic order quantity, D is the demand, S is the fixed cost of each order, and H is the annual storage cost per unit of consumable. By allocating the annual storage cost by month, the formula can more accurately reflect the changes in monthly demand.

[0098] Specifically, the inventory management and replenishment decision module 13 updates the quarterly demand and cost parameters of all consumables in real time. For example, for a certain joint prosthesis consumable, if its quarterly demand is 300 pieces, the single-order cost is 500 yuan, and the annual storage cost of a unit consumable is 120 yuan, then the economic order quantity is 100 pieces. The inventory management and replenishment decision module 13 generates an order suggestion based on the above results and sends it to the supply chain system.

[0099] It can be understood that through the dynamic calculation of the economic order quantity model, the inventory management and replenishment decision module 13 can ensure the timeliness of consumable supply while reducing inventory costs. This algorithm-driven replenishment strategy can significantly improve the economic benefits and operational efficiency of inventory management.

[0100] In the embodiment of the present application, the inventory management and replenishment decision module 13 is also used to obtain the safety stock of each high-value consumable; and generate a high-value consumable order quantity based on the inventory information, safety stock and economic order quantity, and the generation formula of the high-value consumable order quantity is:

[0101]

[0102] wherein, is the high-value consumable order quantity, R is the safety stock, and I is the inventory level.

[0103] Specifically, after calculating the economic order quantity, the inventory management and replenishment decision module 13 considers the real-time inventory level and safety stock of the consumable. When the inventory level is lower than the safety stock, the system will first make up the gap through the order quantity. For example, if the current inventory is 50 pieces, the safety stock is 70 pieces, and the economic order quantity is 100 pieces, then the order quantity is 120 pieces. The inventory management and replenishment decision module 13 pushes the final order quantity data to the procurement management system and generates an order task sheet. At the same time, the system can also simulate the impact of different combinations of safety stock and order quantity on operating costs to provide decision-making reference for managers.

[0104] It can be understood that through the dynamic calculation of the economic order quantity and the safety stock, the inventory management and replenishment decision module 13 realizes the fine management of consumable ordering. This not only reduces the risk of consumable shortage, but also reduces the operating costs caused by excessive inventory.

[0105] In the embodiment of the present application, the traceability and reporting module 14 is connected to the high-value consumable management module and the medical information system, and is used to generate consumable use traceability reports and inventory change trend reports, and also to provide visual high-value consumable data information.

[0106] Specifically, the traceability and reporting module 14 generates multi-dimensional visual reports by collecting historical data within the system. For example, the traceability and reporting module 14 can generate the following types of reports: consumable use traceability report: showing the supplier, batch, production date and use of consumables, ensuring that when recall or inspection is needed, the flow of relevant consumables can be quickly located. Inventory change trend report: analyzing the change curve of inventory data over time, providing a dynamic display of historical inventory levels, allocation and consumption, supporting managers in formulating inventory strategies. Department use efficiency report: assesses the utilization efficiency of consumables in different departments, identifies possible resource waste or shortage problems, and facilitates resource allocation in hospitals.

[0107] It can be understood that the traceability and reporting module 14, through the structured analysis and visual presentation of data, not only improves the transparency of hospital operation, but also provides a scientific basis for decision makers, which helps to further optimize the use and management of consumables.

[0108] The medical high-value consumable management system 10 provided by the embodiments of the present application realizes fine management and intelligent replenishment decision of high-value consumables by integrating the high-value consumable management module 11, the follow-up surgery module 12, the inventory management and replenishment decision module 13 and the traceability and reporting module 14. The system ensures the traceability of each consumable through the application of unique device identification (UDI) and globally unique identifier (GUID), and improves the transparency of the consumable use process. The system can obtain the use of high-value consumables in the surgical process in real time, and update the inventory information synchronously, ensuring the accuracy and real-time of the inventory data. At the same time, the system predicts the demand for high-value consumables based on the long short-term memory network (LSTM) prediction model, helping hospitals to understand the future consumption trend in time. Combined with the economic order quantity (EOQ) model, the system can automatically calculate the optimal order quantity, ensuring sufficient inventory without causing resource waste, and reducing the inventory cost of the hospital. The integrated management mode of the system effectively reduces the errors and omissions of manual operation, improves the management efficiency of high-value consumables in hospitals, and provides real-time data analysis and decision support for hospitals, which helps to optimize resources and control costs in hospitals.

[0109] Figure 2 is a schematic diagram of the modules of the medical high-value consumable management system provided by another embodiment of the present application. Unlike the medical high-value consumable management system 10 shown in Figure 1 , the medical high-value consumable management system 10a shown in Figure 2 , the medical high-value consumable management system 10a further includes an allocation module 15 and a cost confirmation module 16.

[0110] In the embodiments of the present application, Figure 2The high-value consumable management module 11, the follow-up surgery module 12, the inventory management and replenishment decision module 13, and the traceability and reporting module 14 shown in FIG. 1 are the same as or similar to those in the first embodiment, and are not described here. Figure 1

[0111] In the embodiments of the present application, the allocation module 15 is configured to obtain allocation requirements and inventory information of all departments. An allocation scheme is generated according to a linear programming algorithm, inventory sufficiency, and allocation cost. The inventory levels of all departments are updated after allocation, and the allocation result is output. The main function of the allocation module 15 is to generate an optimal allocation scheme according to the inventory of each department in the hospital and the consumable demand by using a linear programming algorithm. First, the allocation module obtains the inventory information of all departments and the allocation requirements of each department in real time by interfacing with the inventory management system. These information includes the current inventory quantity, expected demand quantity, and allocation demand quantity of each department. Based on these data, the module can determine which departments have excess inventory and which departments are facing a shortage of consumables, thereby providing basic data for allocation decisions. The allocation module 15 uses a linear programming algorithm to optimize the allocation path of consumables, with the goal of minimizing the total cost in the allocation process.

[0112] Specifically, the objective function of the linear programming algorithm is:

[0113]

[0114] where x ij is the quantity of consumables allocated from department i to department j, and c ij is the allocation cost from department i to department j. Through this optimization, the system can automatically select the optimal allocation path according to the allocation cost and inventory status between different departments, and calculate the quantity of consumables that need to be allocated on each path.

[0115] It can be understood that by using the linear programming algorithm, the allocation module 15 can find the optimal resource allocation scheme among multiple departments, minimize the logistics cost and allocation time in the allocation process, and ensure efficient use of resources within the hospital. At the same time, the system can update the inventory level of each department in real time and output the allocation result, providing a basis for subsequent replenishment and inventory management.

[0116] In the embodiments of the present application, the constraint condition of the objective function is:

[0117]

[0118] where s i is the current inventory of department i, d j is the demand of department j, and S min ​The safety stock value is used as a constraint. The constraints are used to limit the allocation amount to not exceed the available inventory of the department being allocated, to meet the demand of the receiving department after allocation, and to keep the inventory of each department above the safety stock. The constraints ensure that the allocation amount does not exceed the existing inventory of a certain department, avoiding the situation that the inventory is allocated too much and the department runs out of consumables. The allocation scheme can also meet the demand of the department, avoiding the situation that the normal operation of the department is affected due to lack of necessary consumables. In addition, the inventory of each department after allocation is guaranteed to be above the safety stock level, thereby avoiding problems such as shortage of medical equipment or interruption of surgery due to insufficient inventory.

[0119] It can be understood that these constraints enable the allocation scheme to optimize the allocation cost while fully considering the inventory safety, demand satisfaction and inventory utilization efficiency of the department, ensuring the stability and efficiency of the entire hospital resource allocation. Through these reasonable constraints, the system can intelligently allocate resources between departments to maximize the sustainability of the hospital.

[0120] In the embodiments of the present application, the cost confirmation module 16 is used for cost accounting of high-value consumables used in surgery, including: recording high-value consumable use information through a unique device identifier. Matching the price, batch and corresponding patient's cost list of the high-value consumable. Synchronizing the cost list to the hospital financial management system.

[0121] Specifically, the cost confirmation module 16 is responsible for recording the cost accounting of high-value consumables used in surgery. This module automatically obtains the information of high-value consumables used in each surgery by interfacing with the hospital's high-value consumable management system, including the unique device identifier, price, batch number of the consumable, and the patient information corresponding to the consumable. Through the unique device identifier, the system can accurately record the use of each consumable and match this information with the patient's cost list. The cost confirmation module 16 first obtains the detailed information of each high-value consumable used in surgery by scanning or manually inputting the device identifier. Then, the system calculates the cost of each consumable in the surgery according to the price and batch information of each consumable. Next, the system checks all the cost information of high-value consumables with the patient's cost list to ensure data accuracy. Finally, all the cost lists that have been checked without error are synchronized to the hospital's financial management system for further settlement and financial report generation.

[0122] It can be understood that through seamless integration with the hospital information system and the financial management system, the cost confirmation module 16 can achieve efficient and accurate cost accounting, avoiding errors and delays that may be caused by manual accounting. This automated cost confirmation process can improve the efficiency of hospital financial management and ensure the transparency and accuracy of patient costs, thereby optimizing the financial operations and medical service quality of the hospital.

[0123] The medical high-value consumable management system 10a provided by the embodiment of the present application adds a requisition module and a cost confirmation module on the basis of the system 10, further improving the flexibility and comprehensiveness of the system. The requisition module optimizes the consumable requisition decision among departments by integrating a linear programming algorithm. By monitoring the inventory level and requisition demand of each department in real time, the system can automatically calculate and recommend the best requisition plan, ensuring the efficient flow of consumables among different departments and minimizing the overstock or shortage of inventory. The cost confirmation module automatically calculates the cost of high-value consumables used during surgery by interfacing with the hospital financial management system, ensuring the accuracy and transparency of the cost. The system can achieve accurate billing of high-value consumables by matching the unique device identifier with patient information, preventing cost omission or errors due to improper use of consumables. The further optimization of the system enables the hospital to not only improve the accuracy of inventory management and replenishment decision-making, but also achieve intelligent and automated processing in the requisition and cost confirmation processes, greatly reducing manual operations, improving operational efficiency and financial accuracy, and promoting the development of hospital high-value consumable management towards higher efficiency, transparency and intelligence.
