From the analysis of the business process of pharmacy dispensing and single-dose medicine distribution completed by the system of the present invention, the business data stored in the business database of the system is based on medicines, and takes medicines as a link with prescribing doctors, pharmacists, clinical nurses and Patients are related to each other: the prescribing doctor issues medical orders and electronic prescriptions according to the patient's symptoms; the pharmacist completes the pharmacy distribution according to the electronic prescription and provides single-dose packaging drugs; the clinical nurse takes the single-dose medicine back to the ward, and then distributes the single-dose medicine to matched patients. When summarizing and abstracting the information involved in the above process, it is found that there are five types of key data, namely drug information, prescribing doctor information, pharmacist information, clinical nurse information, and patient information. Their interrelationships are shown in Figure 6.

Therefore, the data model of the drug placement, distribution and traceability system based on digital labels is designed around a core data. The data model has a center and four roles. One center is drug information, which represents all kinds of drug information circulating in the hospital; the four roles are prescribing doctor information, pharmacist information, clinical nurse information, and patient information. Prescribing doctor information includes the prescribing doctor’s identity information, when, where, and for which patient the doctor’s order and electronic prescription were issued, and what specific content is there in the doctor’s order and electronic prescription. The pharmacist information includes the identity information of the pharmacist, when, where, and which patient's electronic prescription is filled and the results of the filling are completed. The clinical nurse information includes the identity information of the clinical nurse, when, where, which single dose was delivered to which patient, and so on. Patient information includes the patient's identity information, when and where he was admitted for diagnosis and treatment, which department the disease belongs to, which bed in which ward he is hospitalized in, and other information. These four types of role information center on drug information and are closely integrated for the purpose of patient drug safety.

In the multi-dimensional traceability management of drugs, based on this data model, it is possible to track the use records of drugs from any participating role of the drug (prescriber, pharmacist, clinical nurse, patient), or to track all information related to the drug based on drug information. Associated participant (prescriber, pharmacist, clinical nurse, patient) information. For example, it is possible to trace back all the medication history information of prescription doctors, pharmacists, clinical nurses, and patients in a specified period of time, and also trace back all patients who have taken the drug within a specified period of time through drug batch information, and prescribe the drug. The doctor who prescribes the medicine, and the clinical nurse who dispenses the medicine.

The system of the present invention is centered on patient medication safety, and provides three functions to complete drug placement in pharmacies, drug distribution in wards, and drug traceability management:

(A) Pharmacy dispensing: The dispensing terminal obtains the medical orders and electronic prescriptions of inpatients from the HIS system through the application server, and then disposes according to the electronic prescriptions. During the process of placing medicines, RFID/QR code/barcode readers are used to collect the drug information on the labels of the medicine packaging boxes and display them on the display screen of the medicine placing terminal. Then call the system service function and business data processing function of the application server to complete the comparison and verification of prescription drug information and physical drug information to ensure that the physical drug meets the prescription requirements; The sound and light alarm form sends out an alarm prompt to the pharmacist.

(B) Dispensing medicine in the ward: the single-dose drug dispensing terminal controls the RFID/QR code/barcode reader to collect the single-dose drug information on the label of the single-dose drug packaging box and the patient information on the RFID digital wristband worn by the patient, Call the corresponding function of the application server to complete the comparison and verification of the drug information and patient information of the single-dose drug with the drug information and patient information on the prescription, the patient information of the single-dose drug and the scanned patient information, to ensure that the single-dose drug is consistent with the electronic The matching relationship between prescription and patient is correct. Once the verification result is found to be wrong, the single-dose drug dispensing terminal will send an alarm to the clinical nurse in the form of sound and light alarm; after the verification is passed, the single-dose drug dispensing terminal will also display the prescription drug information and its image on the single-dose drug The display screen of the dispensing terminal is used for clinical nurses to manually check the drug image and the single dose of the drug, and only after confirming that the shape and color of the two are consistent, the drug is released to ensure the safety of the patient's medication.
