Description

Technical Field

[0001] The present invention relates to the technical field of blood inventory management, and in particular to a method and system for reusing radio frequency tags for blood inventory management. Background Art

[0002] The blood in the blood station system includes: whole blood, red blood cells, plasma, platelets, etc. At present, each bag of blood uses an ordinary QR code label or RFID radio frequency label, both of which are consumables and disposable. Ordinary QR code labels are low in cost and low in efficiency. Each bag needs to be scanned, which is extremely inefficient and prone to errors, especially during inventory counting.

[0003] RFID tags can be used for large-scale storage and inventory management, and the inventory efficiency is extremely high. Reusable RFID tags are usually used for identification, which greatly reduces costs and improves efficiency. In addition, the blood inventory management system is a vital part of medical institutions. It not only needs to effectively manage the storage and outbound information of blood, but also needs to be able to accurately predict blood demand and dispatch blood supply in a timely manner. This system is not only related to the life safety of patients, but also directly affects the operating efficiency and cost control of hospitals.

[0004] Therefore, a method and system for reusing radio frequency tags for blood inventory management are proposed. Summary of the invention

[0005] The object of the present invention is to provide a method and system for reusing radio frequency tags for blood inventory management to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, one of the purposes of the present invention is to provide a method for reusing radio frequency tags for blood inventory management, comprising the following steps: S1. The collected blood is assigned a corresponding radio frequency tag of the carrier, and the radio frequency tag records the basic information of the blood; S2, read the radio frequency tag information and store the blood, record the different blood stored in the corresponding carrier, and verify it by the number of empty carriers; S3. Obtain blood storage information, classify blood information, obtain the daily blood outflow quantity of different blood types, predict the blood demand of different blood types, and conduct real-time inventory of blood in the blood bank. If the demand for the required blood type is lower than the predicted blood type, an alarm is used to notify the staff; S4. When the blood is shipped out of the warehouse, the QR code and RFID tag information are read and verified, and then the RFID tag content of the corresponding blood distribution is cleared for standby use.

[0007] As a further improvement of the technical solution, the basic information of the blood is recorded in the radio frequency tag in S1, and the basic information includes a unique identifier of the blood, collection time, collector information, and blood type.

[0008] As a further improvement of the technical solution, CCD camera technology is used in S2 to judge the blood storage, so as to avoid the situation that the blood information has been written into the carrier's radio frequency tag but the actual blood has not been put into the carrier.

[0009] As a further improvement of the technical solution, the CCD camera technology is used to judge the blood storage, which specifically includes the following steps: Equipment installation and debugging: Install CCD cameras of appropriate quantity and angle at key locations where blood is stored, connect the cameras to the image processing system, and debug them to ensure clear images and stable transmission; Set up a shooting trigger mechanism: When the vehicle enters the storage area, the sensor triggers the device to start the CCD camera to shoot; Image acquisition and processing: The CCD camera quickly captures the image of the carrier, and the image is transmitted to the image processing system in real time. The image processing system uses a preset algorithm to analyze the image, extract the color, shape, texture and other features in the image, and compare them with the preset features of blood; Result judgment: Based on the image analysis results, determine whether there is blood in the carrier. If the image features meet the criteria for blood, it is determined that blood has been placed in the carrier; otherwise, it is determined that blood has not been placed in the carrier.

[0010] Alarm and processing: If it is determined that no blood has been placed in the carrier but the blood information has been written into the RFID tag, the system will issue an alarm. After receiving the alarm, the staff will check and process the carrier.

[0011] As a further improvement of the technical solution, the step of reading the radio frequency tag information and storing the blood in S2 includes the following steps: S2.1. Read the RFID tag information. Based on the information provided by the RFID tag, the system safely stores the blood on the corresponding carrier. S2.2. Record and manage the number of empty carriers to ensure that each RFID tag is correctly associated with the blood, and verify by comparing the amount of blood recorded by the RFID tag with the actual amount of blood in the carrier.

[0012] As a further improvement of the technical solution, the step of obtaining blood storage information in S3 and performing blood inventory management and prediction includes the following steps: S3.1. Collect the blood information stored, classify and store the collected information; S3.2. Establish a prediction model, obtain historical blood delivery data trends, systematically predict the future demand for each blood type, adjust the blood inventory strategy based on the prediction results, and ensure that the needs of medical institutions for different blood types can be met in a timely manner.

[0013] As a further improvement of the technical solution, the weighted moving average algorithm is used in S3.2 to predict the blood demand of each blood type, and the formula is as follows: ; in, It's time Quantity of demand; It's time The actual amount of blood shipped out; It is the smoothing coefficient, which usually takes a value between 0 and 1, indicating the weight of the demand in the previous period. The value means that historical demand data is given more attention. A value of 0 means giving more importance to recent data.

[0014] As a further improvement of the technical solution, the management of the blood outbound process and label clearing in S4 are as follows: S4.1. Use radio frequency tag equipment to read the blood radio frequency tag and verify the information when the blood is shipped out.

[0015] S4.2. After confirming that the blood has been shipped out of the warehouse, the information inside the RFID tag of the corresponding blood distribution is cleared. The cleared tag can be reused to be distributed to new blood.

[0016] A second object of the present invention is to provide a radio frequency tag reuse system for blood inventory management, comprising any one of the radio frequency tag reuse methods for blood inventory management described above, comprising a radio frequency tag allocation unit (100), an information storage unit (200), a prediction unit (300) and a storage out management unit (400); The radio frequency tag distribution unit (100) is used to collect blood and distribute corresponding radio frequency tags; The information storage unit (200) reads the radio frequency tag information through the radio frequency tag reading device of the carrier and stores the blood, recording different blood and storing them in corresponding carriers; The prediction unit (300) writes the blood information into the radio frequency tag through the radio frequency tag device, classifies the blood information in the information storage unit (200), obtains the daily blood output quantity of different blood types, and predicts the blood demand of different blood types; The outbound management unit (400) is used to read the radio frequency tag information when the blood is outbound, and clear the radio frequency tag information content of the outbound carrier for standby use.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The method for reusing radio frequency tags for blood inventory management adopts reusable radio frequency tags, which can accurately and efficiently assign radio frequency tags to the collected blood and record basic information, provide reliable data support for blood inventory management, improve the accuracy and efficiency of blood management, ensure that each sample has a unique and detailed identification, facilitate fast and accurate acquisition of basic information of blood, reduce errors in manual search and recording, and provide basic data support for subsequent warehousing, outbound and inventory management.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 5As shown, one of the purposes of the present invention is to provide a method for reusing a radio frequency tag for blood inventory management, comprising the following steps: S1. The collected blood is assigned a radio frequency tag of a corresponding carrier, and the radio frequency tag records the basic information of the blood; When managing the blood inventory, due to the large blood base, manual query of blood information is labor-intensive and prone to identification errors, which affects the efficiency of the blood bank inventory. Therefore, the basic information of the blood is recorded in the RFID tag in S1. The basic information includes the unique identifier of the blood, collection time, collector information, and blood type.

[0023] When using it, first ensure that there are a sufficient number of blank RFID tags and functioning reading and writing devices. These devices should be compatible with the inventory management system and have the ability to write and read RFID tag information. During the blood collection process, relevant basic information should also be recorded, including blood type, blood volume and collection date. This information should be accurately recorded in the collection form or electronic record system. Connect the reading and writing equipment to the inventory management system, establish a connection between the reading and writing equipment and the blood inventory management system to ensure that data can be acquired and transmitted in real time, select a blank RFID tag, select a blank tag from the prepared RFID tags, and use the reading and writing equipment to write the basic information of the collected blood, such as blood type, blood volume and collection date, into the RFID tag. During the writing process, data verification and confirmation should be performed to ensure the accuracy of the information. For example, if the collected blood is type A, the blood volume is 400 ml, and the collection date is August 7, 2024, then this information will be accurately written into the RFID tag. Attach the RFID tag with written information firmly to the corresponding blood container to ensure that the tag is always associated with the sample and will not fall off or be confused. The information written into the RFID tag should be synchronized to the blood inventory management system in real time for storage and backup for subsequent query, statistics and management operations.

[0024] Through the above series of steps, RFID tags can be accurately and efficiently assigned to the collected blood and basic information can be recorded, providing reliable data support for blood inventory management, improving the accuracy and efficiency of blood management, ensuring that each sample has a unique and detailed identification, facilitating the rapid and accurate acquisition of basic blood information, reducing manual search and recording errors, and providing basic data support for subsequent warehousing, outbound and inventory management.

[0025] In order to ensure the accuracy of the blood storage information and avoid the situation where the label information is inconsistent with the actual sample, S2 reads the radio frequency tag information and stores the blood, records the different blood stored in the corresponding carrier, and verifies it through the number of empty carriers; S2 uses CCD camera technology to judge the entry of blood into the storage, avoiding the situation where the blood information has been written into the carrier's RFID tag but the actual blood has not been put into the carrier; CCD photography technology is used to judge the blood storage, which specifically includes the following steps: Equipment installation and debugging: Install CCD cameras of appropriate quantity and angle at key locations where blood is stored, connect the cameras to the image processing system, and debug them to ensure clear images and stable transmission; Set up a shooting trigger mechanism: When the vehicle enters the storage area, the sensor triggers the device to start the CCD camera to shoot; Image acquisition and processing: The CCD camera quickly captures the image of the carrier, and the image is transmitted to the image processing system in real time. The image processing system uses a preset algorithm to analyze the image, extract the color, shape, texture and other features in the image, and compare them with the preset features of blood; Result judgment: Based on the image analysis results, determine whether there is blood in the carrier. If the image features meet the criteria for blood, it is determined that blood has been placed in the carrier; otherwise, it is determined that blood has not been placed in the carrier.

[0026] Alarm and processing: If it is determined that no blood has been placed in the carrier but the blood information has been written into the RFID tag, the system will issue an alarm. After receiving the alarm, the staff will check and process the carrier.

[0027] Data recording: Each captured image, analysis result and processing status will be recorded in the database.

[0028] S2 reads the radio frequency tag information and stores the blood, including the following steps: S2.1. Read the RFID tag information. Based on the information provided by the RFID tag, the system safely stores the blood on the corresponding carrier. S2.2. Record and manage the number of empty carriers to ensure that each RFID tag is correctly associated with the blood, and verify by comparing the amount of blood recorded by the RFID tag with the actual amount of blood in the carrier.

[0029] During specific use, ensure that the storage area is clean and tidy, the carriers are neatly arranged and clearly classified, turn on the radio frequency reading device and connect it to the inventory management system, use the robot to pick up the blood to be stored, and bring it close to the sensing area of ​​the radio frequency reading device. The device reads the basic information of the blood in the label, such as blood type, blood volume and collection date, and automatically transmits it to the inventory management system. According to the read information, the blood is accurately placed in the carrier of the corresponding type and specification. For example, 400 ml of type A blood is placed in the carrier area marked "400 ml of type A blood". In the inventory management system, the specific location and number of the carrier where the blood is stored are recorded. After a batch of blood is stored, the remaining empty carriers are counted, and the actual amount of blood stored is compared with the theoretical storage quantity calculated through the number of empty carriers. For example, there are 50 empty carriers initially, and 10 remain after the storage operation. The theoretical storage quantity should be 40. If the actual number of blood warehousing recorded in the system is also 40, the review is passed; if it is inconsistent, the warehousing process needs to be rechecked to find out the problem. After confirming that the review is correct, the batch of blood is marked as completed in the inventory management system.

[0030] For example, suppose the first batch of 20 blood type A blood, 200 ml, was put into storage, and the initial empty carriers were 30. After storage, 10 remained and passed the review. The second batch of 15 blood type B blood, 300 ml, was put into storage, and the initial empty carriers were 20. After storage, 5 remained and passed the review again. And so on, ensuring the accuracy of each batch of storage, reasonable storage and empty carrier review improves the accuracy and reliability of inventory management, and helps to timely discover errors in the storage process, ensuring the safety and traceability of blood.

[0031] S3. Obtain blood storage information, classify blood information, obtain the daily blood outflow quantity of different blood types, predict the blood demand of different blood types, and conduct real-time inventory of blood in the blood bank. If the demand for the required blood type is lower than the predicted blood type, an alarm is used to notify the staff; In order to scientifically classify and finely manage blood, better meet clinical blood demand, plan blood collection and inventory adjustment strategies in advance, and avoid blood shortage or surplus, blood storage information is obtained in S3 to manage and predict blood inventory, including the following steps: S3.1. Collect the blood information stored, classify and store the collected information; S3.2. Establish a prediction model, obtain historical blood delivery data trends, systematically predict the future demand for each blood type, adjust the blood inventory strategy based on the prediction results, and ensure that the needs of medical institutions for different blood types can be met in a timely manner.

[0032] The establishment of a prediction model specifically includes the following steps: Data collection and organization: Collect a large amount of historical blood delivery data, including the delivery quantity of each blood type in different time periods, different regions, and different medical institutions. At the same time, collect data on related factors that may affect blood demand, such as seasons, holidays, disease prevalence, population growth data, etc.

[0033] Data cleaning and preprocessing: Check the completeness and accuracy of the data, handle missing values ​​and outliers, and standardize or normalize the data so that different variables can be compared and calculated.

[0034] Feature engineering: Extract meaningful features from the raw data. For example, convert time data into categorical features such as seasons and months, or calculate the change rate of blood demand in adjacent time periods, etc., screen and select features, and remove features with low relevance or little contribution to the prediction results; Model training: The model can use time series analysis, regression analysis and other methods, combined with multiple influencing factors, to predict the future demand for each blood type.

[0035] After the system generates prediction results based on the model, blood bank managers can adjust inventory strategies based on these results. If it is predicted that the demand for type A blood will increase significantly in the future, managers can increase the reserve of type A blood in advance, or adjust the blood collection plan and increase the collection of type A blood. Based on the forecast of demand based on the number of outbound shipments, blood collection and inventory adjustment strategies can be planned in advance to avoid blood shortages or surpluses, and scientific classification and refined management of blood can be achieved to better meet clinical blood needs. Real-time inventory and alarm functions can promptly remind staff to replenish insufficient blood types to ensure the timeliness and stability of blood supply.

[0036] S3.2 uses a weighted moving average algorithm to predict the blood demand for each blood type. The formula is as follows: ; in, It's time Quantity of demand; It's time The actual amount of blood shipped out; It is the smoothing coefficient, which usually takes a value between 0 and 1, indicating the weight of the demand in the previous period. The value means that historical demand data is given more attention. A value of 0 means giving more importance to recent data.

[0037] Real-time blood inventory and alerts for blood banks include the following steps: Real-time inventory: Regularly or in real time check the quantity of each blood type currently in stock.

[0038] Alert Mechanism: Set a Threshold ,If the actual inventory of a certain blood type is lower than the predicted demand, the system triggers an alarm.

[0039] Assume that yesterday's forecast demand was , today's actual outbound volume is , smoothing coefficient =0.2, then today's forecast demand , can be calculated as: ; if It is updated in real time and can calculate new ; Predictive models and real-time monitoring can effectively manage blood inventory, ensure timely response to changes in demand, and prompt staff to replenish or adjust blood inventory when necessary through alarms S4, when the blood is out of the warehouse, the QR code and the RFID tag information are read and checked, and then the RFID tag content of the corresponding blood distribution is cleared for standby use; In order to enhance the accuracy of blood delivery and reduce the risk of error, the management and label clearing of blood delivery process in S4 are as follows: S4.1. Use radio frequency tag equipment to read the blood radio frequency tag and verify the information when the blood is shipped out.

[0040] S4.2. After confirming that the blood has been shipped out of the warehouse, the information inside the RFID tag of the corresponding blood distribution is cleared. The cleared tag can be reused to be distributed to new blood.

[0041] Double information verification (QR code and RFID tag) enhances the accuracy of blood storage, reduces the risk of errors, clears the RFID tag content for next use, increases the reuse rate of the tag, and reduces costs.

[0042] The second object of the present invention is to provide a radio frequency tag reuse system for blood inventory management, including any one of the radio frequency tag reuse methods for blood inventory management described above, including a radio frequency tag allocation unit 100, an information storage unit 200, a prediction unit 300 and a storage management unit 400; The radio frequency tag distribution unit 100 is used to collect blood and distribute corresponding radio frequency tags; The information storage unit 200 reads the radio frequency tag information through the radio frequency tag reading device of the carrier and stores the blood, recording different blood and storing them in the corresponding carrier; The prediction unit 300 writes the blood information into the radio frequency tag through the radio frequency tag device, classifies the blood information in the information storage unit 200, obtains the daily blood output quantity of different blood types, and predicts the blood demand of different blood types; The outbound management unit 400 is used to read the radio frequency tag information when the blood is outbound, and clear the information content of the radio frequency tag that has been outbound for standby use.
