Intelligent drug delivery and auditing system

Abstract

A smart drug delivery and auditing system includes a drug supply system, a drug auditing system, an electronic device, and a barcode sensing unit. The drug supply system includes a caregiver barcode, a patient barcode, at least one medication bag barcode, and an IV pump. The IV pump has at least one pump barcode. The drug auditing system interfaces with a hospital's medical information system, which includes a barcode-based drug delivery system (BCMA) and stores at least one patient's medical order. The medical information system and the drug auditing system can respectively provide a first operating interface and a second operating interface through the electronic device. The second operating interface allows scanning the barcodes of the caregiver, the patient, and the medication bag. The prescription will then be displayed on the first operating interface. Following this, the pump barcode is scanned via the barcode scanner on the first operating interface. The medication name, total dosage, and flow rate in the prescription are wirelessly transmitted to the infusion pump. Simultaneously, the prescription is also displayed on the second operating interface. The caregiver only needs to compare the two versions of the prescription to ensure accuracy. This reduces the workload for caregivers, eliminates the need for manual settings, and minimizes medication errors, thereby improving medication safety.

When the infusion pump is completed, the drug auditing system will automatically load the information into the nursing record page. The nursing record page displays information such as the start time of infusion, the end time of infusion, the amount of fluid administered, the reason for the change in flow rate, the amount of large dose injected, and the information returned on the hour.

4. The intelligent drug delivery and auditing system as described in claim 3, wherein, The second user interface includes a new patient page, which includes a patient information display section and a pump information display section. The patient information display section displays the patient's basic information, while the pump information display section displays the medication, total dosage, route of administration, and target flow rate of the prescribed medication. The pump information display section also includes a pump barcode input section, which scans the pump barcode of the IV pump to input the pump barcode into the pump barcode input section.

5. The intelligent drug delivery and auditing system as described in claim 4, wherein, The second operating interface also includes a real-time infusion status page, which includes a patient status display section, an abnormality selection section, and a completion section. The patient status display section is used to display the infusion status and also includes a detailed data section. When the patient status display section shows an abnormal flow rate, the detailed data section can be selected to import the data into the abnormality selection section, which is used to select the cause of adjustment. By selecting the completion section, the abnormality selection section will automatically return to the patient status display section and display normal status. At the same time, it will automatically be sent back to the medical information system and displayed on the nursing record page.

6. The intelligent drug delivery and auditing system as described in claim 5, wherein, After scanning the pump barcode, the medical order will be transmitted to the infusion pump and displayed on the screen. At the same time, it will be displayed on the real-time infusion status page of the second operation interface. After the nurse confirms that the medical order is correct, she will press the button group on the operating device. The infusion pump will then drive the drug delivery device to start the infusion. At the same time, the drug audit system will compare the medical order set on the display screen again.

7. The intelligent drug delivery and auditing system as described in claim 5 or 6, wherein, The drug audit system compares the prescription with the settings on the display screen. If the prescription is correct, the status bar on the patient status display will show normal status, indicating that the settings match the prescription. Conversely, if the flow rate is abnormal, the patient status display will change color and a warning window will pop up below to remind the nursing staff that the infusion flow rate is abnormal.

8. The intelligent drug delivery and auditing system as described in claim 5, wherein, The second user interface also includes a history page that displays the patient's previous infusion records. The history page includes a patient history section, which can be accessed by selecting the detailed information section.

9. The intelligent drug delivery and auditing system as described in claim 5, wherein, The drug audit system features automatic unbinding upon completion of infusion. After a patient's infusion ends, the system automatically unbinds the displayed nursing staff from the patient and allows a new patient to be bound to it.
