Description

BACKGROUND OF THE INVENTION

Field of the Disclosure

The present application relates generally to a system and device for drug preparation.

Description of the Related Art

Patient specific medication is prepared by pharmacy technicians in a sterile field based on a printed preparation label that is approved by a pharmacist. The process of preparation is largely manual, although there are various automation technologies on the market. These automation technologies generally fall into three categories: workflow software; compounders; and fully-automated robots. Workflow software provides order management, prioritization, approvals within the pharmacy, and documentation. Workflow software solutions typically require some level of IT integration as well as hardware, such as a scale, a camera, and monitors. Compounder solutions are semi-automated solutions that automate certain key aspects of the sterile compounding process with significant technician intervention. Fully-automated robotic solutions are complex and typically require significant reconfiguration of the central pharmacy, including construction.

Referring to FIG. 1, a drug transfer device 10 according to one aspect or embodiment of the present application includes a syringe interface 12, a drive member 14, a motor 16, a position sensor 18, a wireless communication device 20, an information reader 22, and a processor 24. The drug transfer device 10 is configured to receive a plurality of syringe barrel sizes. As discussed in more detail below, the drug transfer device 10 is utilized for transferring and dosing medication between various containers, such as transferring a dose from a vial to a syringe to an intravenous bag or container. The drug transfer device 10 may be utilized in connection with other components such a vial adapter, syringe adapter, patient connector, etc. The motor 16, the position sensor 18, the wireless communication device 20, the information reader 22, and the processor 24 are positioned within a housing 28, although these components or portions of these components may be positioned outside of the housing 28. A portion of the drive member 14 is also received within the housing 28, although other suitable arrangements may be utilized.

The drive member 14 is movable relative to the syringe interface 12. The drive member 14 is movable such that a plunger interface 30 of the drive member 14 can be moved toward the housing 28 or away from the housing 28. The drive member 14 is configured to move a stopper 32 within a syringe barrel 34 when the syringe barrel 34 is engaged with the syringe interface 12, as shown in FIG. 1. The motor 16 is configured to move the drive member 14, which, in turn, moves the stopper 32 within the syringe barrel 34 to either aspirate fluid into the syringe barrel 34 or expel fluid from the syringe barrel 34. The position sensor 18 is configured to measure a position of the drive member 14. In particular, the position sensor 18 measures the position of the plunger interface 30 of the drive member 14 such that the position of the stopper 32 of the syringe barrel 34 can be precisely determined. The wireless communication device 20 is configured to send and receive information. The information may be medication dosage information, dosage documentation, patient documentation, a status of the drug transfer device, etc. The information reader 22 is configured to receive information from an information target 36. The processor 24 is in communication with the motor 16, the position sensor 18, the wireless communication device 20, and the information reader 22. The processor 24 may be one or more processors. The processor 24 may be a microcontroller, although other suitable arrangements may be utilized. The drug transfer device 10 includes a rechargeable battery 38, although other suitable batteries, external power supplies, and power sources may be used in addition to or alternatively to the rechargeable battery 38.

The information reader 22 may be at least one of a barcode reader, an RFID reader, and an NFC reader, although other suitable information readers may be utilized. The information target 36 may be at least one of a barcode, an RFID tag, and an NFC tag, although other suitable information targets may be utilized. The wireless communication device 20 is configured to communicate via at least one of Bluetooth, Wi-Fi, and NFC. The information target 36 is scanned by the information reader 22. For example, a medication label 40 can be provided with the information target 36, which is read by the information reader 22 of the drug transfer device 10. The drive member 14 of the drug transfer device 10 can then be manually, semi-manually, or automatically actuated to aspirate a dose of medication into the syringe barrel 34 based on the information target 36 of the medication label 40. The required dose of medication may be determined based on stored information on the drug transfer device 10 or may be accessed from a server, or other suitable device remotely, via the wireless communication device 20.

Referring again to FIG. 1, the drug transfer device 10 may further include a display 42 and user input interface 44, such as a touch screen, button, knob, etc. The display 42 and the user input interface 44 are connected to the processor 24, with the display 42 configured to display information received by the drug transfer device 10 or stored on the drug transfer device 10. The display 42 and the user input interface 44 may be utilized to operate the drug transfer device 10, although other suitable arrangements, such as remote control of the drug transfer device 10 via a computer terminal or mobile device, may be utilized to operate the drug transfer device 10.

Referring to FIGS. 1 and 2, a system 50 for drug preparation according to one aspect or embodiment of the present application includes the drug transfer device 10 of FIG. 1, a medication workflow system 52 in communication with the drug transfer device 10 via the wireless communication device 20, and at least one information target 36 configured to be read by the information reader 22 of the drug transfer device 10. The medication workflow system 52 may be the BD Cato® system available from Becton, Dickinson and Company, although other suitable medication workflow systems may be utilized. The medication workflow system 52 may be configured to enable order management, prioritization, approvals within the pharmacy, documentation, and other suitable functions.

The system 50 may further include a printer 54 in communication with the drug transfer device 10 and/or the medication workflow system 52. The printer 54 may be wirelessly and/or physically connected to the drug transfer device 10 and/or medication workflow system 52.

The system 50 is configured to enable compounding patient specific doses of medication while ensuring a prescribed medication and medication dose. As discussed above, the medication label 40 can be provided with the information target 36, which is read by the information reader 22 of the drug transfer device 10. The medication label 40 may be generated by the medication workflow system 52 and printed via the printer 54. After the information target 36 is read by the information reader 22, the drive member 14 of the drug transfer device 10 may be manually, semi-manually, or automatically actuated to aspirate a dose of medication into the syringe barrel 34 based on the information target 36 of the medication label 40. The required dose of medication may be determined based on stored information on the drug transfer device 10 or may be accessed from a server and/or the medication workflow system 52 via the wireless communication device 20. The medication label 40 may be printed via the printer based on information provided by the medication workflow system 52 and/or the drug transfer device 10. The medication label 40 may be affixed to the syringe barrel 34 after compounding or a separate container. The drug transfer device 10 may communicate with the medication workflow system 52 to provide automatic documentation of the compounding process.
