Based on the available time and skill type of the personnel node, determine whether there is an available maintenance personnel node among the personnel nodes that have edges with the equipment node to be repaired; if so, use the available maintenance personnel node corresponding to the maximum edge strength of the equipment node to be repaired as the optimal maintenance personnel node, and notify the corresponding personnel of the optimal maintenance personnel node to perform equipment maintenance; if not, use the medical equipment node that belongs to the same type of equipment as the equipment node to be repaired as the alternative medical equipment node; based on the transportation cost and time cost of the alternative medical equipment node, obtain the moving cost of each alternative medical equipment node; use the alternative medical equipment node corresponding to the minimum moving cost as the optimal alternative medical equipment node, and replace the medical equipment corresponding to the equipment node to be repaired with the corresponding medical equipment.
[0015] S1. Construct a relationship network diagram based on the department information, medical equipment information and personnel information in working state; in the relationship network diagram, the nodes include department nodes, medical equipment nodes and personnel nodes, the edges are the work correlation between nodes, and the edge strength is the node attribute matching strength.
[0016] Based on the department information, medical equipment information and personnel information in working state, the complex relationship between medical equipment, personnel and departments is clearly displayed and updated in real time to obtain a relationship network diagram, which is convenient for subsequent intelligent analysis of the operation status of medical equipment based on the node information and edges of the relationship network diagram, and facilitates efficient management of medical equipment.
[0017] Based on the information of departments, medical equipment and personnel that are currently in working state, a graph structure is constructed to clearly show the complex relationships between medical equipment, between medical equipment and personnel, and between medical equipment and departments, and a relationship network diagram is obtained.
[0018] In the relationship network diagram, nodes represent medical equipment, departments, and medical staff entities, including department nodes, medical equipment nodes, and staff nodes. Each node has its own node attribute content and is displayed in the form of a tree structure. The name of the node is the root node of the tree structure, which is convenient for comprehensive reflection of node information and subsequent efficient information retrieval.
[0019] The attributes of the department node include: department name, location, person in charge and department equipment requirements (such as the required equipment type and quantity range), etc.; the attributes of the medical equipment node include: equipment name, department, available time, model, manufacturer, purchase date, equipment operating parameters (such as resolution, scanning speed, etc.), equipment level, equipment function, usage record, maintenance cycle and historical repair and maintenance records; the attributes of the personnel node include: personnel skill type (operation type - medical staff used to operate equipment, maintenance type - maintenance engineers used to repair and maintain equipment), name, department, available time, title and skill assessment records.
[0020] Edges represent the relationship between entities and are the working dependencies between nodes.
[0021] If the medical equipment and personnel belong to the department, then there will be edges between the corresponding medical equipment nodes and personnel nodes and the department nodes respectively; if there is information transmission between medical equipment (there is a collaborative, supporting or backup relationship between the equipment), there will be edges between the corresponding medical equipment nodes; if there is a historical operation relationship or a historical repair and maintenance relationship between the medical equipment and the personnel, there will be edges between the corresponding medical equipment nodes and the personnel nodes.
[0022] The edge strength is the node attribute matching strength, which is obtained based on the product of the node attribute feature vectors of two nodes. The node attribute feature vector is obtained by embedding all the node attribute contents after splicing. The greater the edge strength between the medical equipment node and the department node, the greater the importance weight of the medical equipment in the department, and the greater the impact on the criticality assessment of diagnosis and treatment; the greater the edge strength between the medical equipment nodes, the closer the collaboration, matching or backup relationship between the medical equipment; the greater the edge strength between the medical equipment node and the personnel node, the more skilled the medical staff is in operating the equipment, or the more skilled the maintenance engineer is in repairing the equipment.
[0023] In order to normalize medical equipment maintenance and ensure the normal operation of medical equipment, when the equipment usage time in the medical equipment node usage record meets the maintenance cycle, the personnel node whose skill type belongs to the maintenance type and whose edge strength with the medical equipment node is the maximum value will be used as the optimal maintenance personnel node, and a pop-up window will be popped up to remind the personnel corresponding to the optimal maintenance personnel node to perform equipment maintenance.
[0024] S2. Based on the update information of the medical device node, and / or the data transmission information between the medical device nodes, determine whether the medical device node fails; if the medical device node fails, treat the medical device node as a device node to be repaired and execute S3.
[0025] According to the updated information of medical device nodes in the relationship network diagram and the data transmission information between medical device nodes, it is automatically detected whether the medical device node has a fault and performs corresponding operations, thereby improving the efficiency and accuracy of medical device fault detection and improving the intelligence of medical device management.
[0026] First, based on the update information of the medical device node and / or the data transmission information between the medical device nodes, it is determined whether the medical device node fails.
[0027] The specific judgment method is: if the equipment operating parameters of the medical equipment node are not within the corresponding standard operating parameter range, or / and the weighted sum of the operating scores of all equipment operating parameters of the medical equipment node is less than the comprehensive operating score threshold, or / and the equipment data transmission speed between the medical equipment nodes is less than the transmission speed threshold, or / and the equipment data transmission format between the medical equipment nodes is abnormal, then the medical equipment node fails.
[0028] The weighted sum of the running scores is obtained by the following formula: , , is the weighted sum of running scores, is the scoring weight of the i-th operating parameter of the equipment, is the operation score of the i-th operation parameter of the equipment, is the i-th operating parameter of the device, is the lower limit of the standard operating parameter range corresponding to the i-th operating parameter of the equipment, is the upper limit of the standard operating parameter range corresponding to the i-th operating parameter of the equipment, is the denominator compensation value to prevent the denominator from being 0. is the total number of equipment operating parameters, M For the total score.
[0029] Finally, if a medical device node fails, the medical device node is treated as a device node to be repaired and S3 is executed.
[0030] S3. Based on the available time and skill type of the personnel node, determine whether there is an available maintenance personnel node among the personnel nodes that have an edge with the node of the equipment to be repaired; if so, use the available maintenance personnel node corresponding to the maximum edge strength of the node of the equipment to be repaired as the optimal maintenance personnel node, and notify the corresponding personnel of the optimal maintenance personnel node to perform equipment maintenance; if not, use the medical equipment node that belongs to the same type of equipment as the node of the equipment to be repaired as the alternative medical equipment node; based on the transportation cost and time cost of the alternative medical equipment node, obtain the moving cost of each alternative medical equipment node; use the alternative medical equipment node corresponding to the minimum moving cost as the optimal alternative medical equipment node, and replace the medical equipment corresponding to the node of the equipment to be repaired with the corresponding medical equipment.
[0031] According to the available time and skill type of the personnel node, determine whether there are currently available maintenance personnel that can be dispatched; if so, the most skilled maintenance engineer for the medical device will be selected as the optimal maintenance personnel node for equipment maintenance based on the edge strength; if not, the transportation cost is calculated based on the location information, transportation cost and time cost of medical equipment nodes that belong to the same type of equipment as the equipment node to be repaired, and the medical equipment corresponding to the minimum transportation cost is replaced with the faulty medical equipment, thereby improving the flexibility and intelligence of medical equipment fault repair and equipment scheduling.
[0032] First, based on the available time and skill type in the personnel node attribute content, it is determined whether there is an available maintenance personnel node among the personnel nodes that have an edge with the equipment node to be repaired. The available maintenance personnel node is a personnel node that has an edge with the equipment node to be repaired and currently has an available time and a maintenance skill type. That is, it is determined whether there is a maintenance engineer who has free time to repair the faulty medical equipment.
[0033] If it exists, the personnel node corresponding to the maximum edge strength of the device node to be repaired, that is, the maintenance engineer who is most skilled in repairing the medical device, will be used as the optimal maintenance personnel node, and the personnel corresponding to the optimal maintenance personnel node will be notified to perform equipment maintenance.
[0034] If it does not exist, a medical equipment node that belongs to the same type of equipment as the equipment node to be repaired, or a medical equipment node that has the same equipment function as the equipment node to be repaired will be used as an alternative medical equipment node; and based on the transportation cost and time cost of the alternative medical equipment node, the moving cost of each alternative medical equipment node is obtained; the alternative medical equipment node corresponding to the minimum moving cost is used as the optimal alternative medical equipment node, and the corresponding medical equipment replaces the medical equipment corresponding to the equipment node to be repaired.
[0035] The above-mentioned moving cost is the sum of the labor cost of handling, the cost of transportation tools, the cost of equipment loss, the loss of equipment downtime and the total time cost.
[0036] Among them, the labor cost of transportation It is obtained by the following formula: , The hourly moving wage is the hourly wage of the movers; is the distance correction factor, is the average transport speed (unit: m / h), For alternative medical device nodes and the device node to be repaired distance.
[0037] Transportation cost The cost of depreciation, maintenance, etc. for each use of the means of transport can be allocated based on historical experience.
[0038] Equipment loss cost , that is, the damage cost of the alternative medical equipment during transportation is obtained by the following formula: , is the equipment loss cost coefficient per unit weight per unit distance (unit: yuan / kg・m), The weight of the alternative medical device (in kilograms).
[0039] Equipment downtime loss , that is, the discontinuation loss of the alternative medical equipment is obtained by the following formula: , The sum of the economic losses and the loss of medical service quality caused by each hour of equipment downtime, The time incurred by alternative medical equipment during non-idle time to replace the equipment to be repaired.
[0040] Total time cost For other time-related fixed costs (such as waiting time for the elevator, etc.), this part is the fixed time cost and can be set based on historical experience.
[0041] Therefore, based on the above formula, the calculation formula for the movement cost is as follows: .
[0042] Simplifying the above formula, we get: .
[0043] Furthermore, in order to optimize the medical equipment management method and further increase the flexibility and rationality of the equipment management method, when there is no available maintenance personnel node, it is determined whether the equipment level of the equipment node to be repaired is higher than the equipment level threshold; if it is not higher, it means that the adverse impact caused by the failure of the corresponding medical equipment of the equipment node to be repaired is small. In order to save maintenance resources, the equipment node to be repaired corresponds to the medical equipment, and then waits for the maintenance engineer in the personnel node with an edge with the equipment node to be repaired, available time, and skill type belonging to the maintenance type to perform maintenance; if it is higher, it means that the impact caused by the failure of the corresponding medical equipment of the equipment node to be repaired is large. In order to reduce losses, the equipment node to be repaired performs the operation of obtaining and replacing the mobile cost of the corresponding alternative medical equipment node. The above equipment level is obtained based on the number of edges of the equipment node to be repaired. The larger the number of edges of the equipment node to be repaired, the higher the equipment level.
[0044] In addition, further, when the outage loss of the medical equipment corresponding to the device node to be repaired is less than the movement cost of all candidate medical equipment nodes, that is, when the outage loss of the medical equipment corresponding to the device node to be repaired is less than the minimum movement cost of all candidate medical equipment nodes, in order to save costs, the maintenance engineer in the personnel node who has an edge with the device node to be repaired, has callable time, and has a maintenance skill type is waited for to perform maintenance. The outage loss of the medical equipment corresponding to the device node to be repaired is obtained based on the outage loss per hour of the faulty medical equipment (the medical equipment corresponding to the device node to be repaired) and the waiting time for maintenance.
[0045] In addition, in order to improve the stability of the medical equipment management method, when there is more than one device node to be repaired, all the device nodes to be repaired are arranged in order from large to small according to the device level, and the operations in S3 are performed in sequence.
[0046] This embodiment also provides a medical equipment intelligent management system, which is used to implement the above-mentioned medical equipment intelligent management method, including: A relationship network diagram generation module is used to construct a relationship network diagram based on the department information, medical equipment information and personnel information in working state; in the relationship network diagram, the nodes include department nodes, medical equipment nodes and personnel nodes, the edges are the working correlation between the nodes, and the edge strength is the node attribute matching strength; A medical device node fault judgment module is used to judge whether a medical device node fails based on the update information of the medical device node, or / and the data transmission information between the medical device nodes; specifically: if the device operating parameters of the medical device node are not within the corresponding standard operating parameter range, or / and the weighted sum of the operating scores of all device operating parameters of the medical device node is less than the comprehensive operating score threshold, or / and the device data transmission speed between the medical device nodes is less than the transmission speed threshold, or / and the device data transmission format between the medical device nodes is abnormal, then the medical device node fails; if the medical device node fails, the medical device node is treated as a device node to be repaired, and the personnel maintenance notification and equipment replacement modules are executed; The personnel maintenance notification and equipment replacement module is used to determine whether there is an available maintenance personnel node among the personnel nodes that have an edge with the equipment node to be repaired based on the available time and skill type of the personnel node; if so, the available maintenance personnel node corresponding to the maximum edge strength of the equipment node to be repaired is used as the optimal maintenance personnel node, and the corresponding personnel of the optimal maintenance personnel node are notified to perform equipment maintenance; if not, the medical equipment node that belongs to the same type of equipment as the equipment node to be repaired is used as the alternative medical equipment node; based on the transportation cost and time cost of the alternative medical equipment node, the moving cost of each alternative medical equipment node is obtained; the alternative medical equipment node corresponding to the minimum moving cost is used as the optimal alternative medical equipment node, and the corresponding medical equipment replaces the medical equipment corresponding to the equipment node to be repaired.
