Reporters obtained the following quote from the background information supplied by the inventors: "Closed system transfer devices (CSTDs) are devices that are used with transferring usually hazardous pharmaceutical agents that can result in contamination. CSTDs allow for a transfer of the pharmaceutical agents, such as a fluid containing hazardous medicine, between medical containers under a closed condition."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "A robotic intravenous automation (RIVA) system, can include a robotically controlled holder configured to manipulate an intravenous (IV) bag and a closed system transfer device (CSTD), and can further include a controller including a processor configured to control the holder. The holder can be a robotic arm.
"The IV bag can include a first fluid port and a second fluid port. The CSTD can include a CSTD port, a spike adapter that is fluidically separated from the CSTD port, and a flexible member connecting the CSTD port to the spike adapter. The first and second fluid ports can be joined together to the spike adapter and the CSTD port to form a CSTD assembly.
"The controller can be configured to control the holder to perform a process of attaching the spike adapter to the first fluid port of the IV bag, grasping the CSTD port based on a predefined dimensional characteristic of the CSTD stored in the controller, manipulating the CSTD port, flexing the flexible member; and attaching the CSTD port to the second fluid port of the IV bag.
"The controller can be configured to control the holder to perform a process of accepting a user command to prepare an IV bag with a particular drug, determining whether the particular drug requires a CSTD, and selecting, by the holder, the CSTD IV bag assembly based on the determining. The process can further include attaching a CSTD syringe containing the particular drug to the CSTD port, and performing a fluid transfer of the particular drug between the CSTD syringe and the IV bag via the CSTD port. The process can further include outputting an indication to place the CSTD IV bag assembly into an inventory rack of the system, and verifying the CSTD IV bag assembly has been placed into the inventory rack of the system. The verifying can include a visual-based verification by image analysis, or an
"The controller can be configured to control the holder to perform a process of testing an attachment of the CSTD port to the second fluid port of the IV bag by pulling the CSTD port away from the second fluid port of the IV bag and measuring a amount of force applied in the pulling, and stopping the testing when the amount of force reaches a predefined amount. The predefined amount can be 5, 10, 20, or 40 lbs. The process can further include attaching a CSTD syringe to the CSTD port, and performing a fluid transfer between the CSTD syringe and the IV bag via the CSTD port and the second fluid port of the IV bag.
"The first fluid port of IV bag can have a different shape than the second fluid port of the IV bag, and the controller can be configured to distinguish between the first and second fluid ports by a sensor. The second fluid port of the IV bag can be a needle port, whereas the first fluid port of the IV bag may not be a needle port.
"The CSTD port can include an alignment structure that coincides with a particular alignment between the CSTD port and the spike adapter, in which the holder and controller can distinguish the particular alignment by holding the CSTD by the alignment structure. The alignment structure can serve as a grasping point for manipulating a CSTD IV bag assembly by the holder.
"The CSTD port can include a cannula, and the CSTD port can include reverse facing barbs on an interior portion thereof that contacts an exterior of the first or second fluid port of the IV bag that can positively lock the CSTD port to the first or second fluid port of the IV bag. The spike adapter can include two membranes.
"The flexible member can have a relatively long, thin and wide cross section that can inhibit selected movement between the CSTD port and the spike adapter. The flexible member can resist a relative twisting motion between the CSTD port and the spike adapter, so that the CSTD port and the spike adapter can have a natural un-stressed position of having parallel axes, with respect to a long axis of each of the CSTD port and the spike adapter.
"The foregoing general description of the illustrative embodiments and the following detailed description thereof are merely exemplary aspects of the teachings of this disclosure, and are not restrictive.
