Abstract: The application of UHF RFID sensing technology can help realize the intelligent management of blood.
Blood can solve a large number of medical problems, but if the blood collection is not standardized, blood storage and use is chaotic, it may become a channel for the transmission of various diseases. However, in the process of blood management, a lot of information is often involved, which brings difficult problems to managers. The application of UHF RFID sensing technology can help realize the intelligent management of blood.
1. RFID blood management system application
1.1 RFID blood collection management
RFID handheld scans the RFID information in the blood donation bar code. Record the name information of the blood collector, and the start and finish time of blood collection. It solves the problem of unclear responsibility in blood management. After blood collection, the donor’s name, gender, blood type, ID number and other information will be written into the RFID chip of the unpaid blood donation card. Increase the speed of the investigation of blood donor data, and the anti-counterfeiting of blood donation cards.
1.2 RFID blood preparation management
The blood will be imported into the software in batches, the test person will publish the test result, the blood test result is qualified, and the corresponding blood label status will be changed to the pending storage status, and the blood can be stored. If the blood test fails, the label status of the corresponding blood will be changed to unqualified, and the system will write the scrap information and scrap reason, etc., to prepare for the follow-up blood tracking.
1.3 RFID blood test management
The preparation time and preparation type of the preparation were recorded by scanning the identification card and blood bag of the preparation by the RFID antenna. After the blood is prepared, the RFID blood bag tag is printed. RFID blood bag tags record blood donation number, blood type, blood type, blood volume and other basic blood information, as well as the preparation of the number, blood collection unit, blood validity period and other effective information.
1.4 RFID blood storage management
Before the staff put the blood box containing the blood bag into the refrigerator, when passing through the smart door, the RFID tag attached to the blood bag enters the reading and writing range of the smart door, and the information on the tag is read out and filtered through the middleware to the background database. At the same time, the system displays information such as blood type, type, and specification on the LCD screen of the smart door. According to the displayed content, the staff will confirm whether the stored data is correct. At the same time, the intelligent door of each blood bag storage time, storage type, storage person, storage refrigerator number and other information is written into the RFID blood management system.
The system issues an exit order, instructing the staff to go to the designated area and take out the specified type, specification and quantity of blood. During the exit process, the system records the exit time, blood expiration date, and other secondary information. The order of blood delivery is determined by the system after reading the information and analyzing it. Require the same specifications of blood, in accordance with the principle of first in, first out, to avoid the phenomenon of overstocking and expired blood waste. For the blood in the blood bank to be tested, unqualified, expired state, through the warehouse intelligent door, the system will issue a prompt sound to ensure the quality of the blood.
1.5 RFID clinical blood management
Before the transfusion, the doctor scans the patient’s wristband label through a handheld computer to confirm the patient’s name, gender, and whether he or she is allergic to the drug. Then scan the RFID blood bag tag to confirm the blood type, blood volume and other information. The patient and the blood are then checked to see if they are a match and can be safely transfused.
1.6 RFID blood tracking management
Scan the RFID blood bag tag through the handheld or desktop reader, according to the RFID identification code to the national blood information center database, find the identity information of the bag of blood, according to the found IP address, enter the provincial blood information center database, find the information of the bag of blood. According to the information, you can know the current state of the bag of blood, whether it is stored in the library or used out of the library, or has deteriorated and scrapped, if it has been used, you can also find all the information of the user.
2. System advantages
1) Accurate inventory without opening the box
2) Rapid batch blood storage
3) Temperature monitoring and recording
4) Improved work efficiency
5) Improve the anti-counterfeiting of blood blood labels
