Systems, apparatus, and methods for fluid infusion
In some embodiments, a system can include a fluid delivery assembly and a drive assembly. The fluid delivery assembly is configured to be releasably mechanically and, optionally, electrically coupled to the drive assembly. When the fluid delivery assembly is releasably coupled to the drive assembly, the drive assembly can control delivery of fluid from the fluid delivery assembly (e.g., to a patient). For example, the drive assembly can be releasably coupled to the fluid delivery assembly to control delivery of fluid from the fluid delivery assembly to provide continuous (e.g., non-pulsatile) fluid flow from the fluid delivery assembly.
Low dose syringe including an air venting system
Medical devices capable of filling liquid into a syringe barrel while evacuating any air from the syringe are described. An exemplary medical device includes a syringe barrel having a tapered sidewall portion for permitting air to vent from the chamber and preventing liquid from exiting the chamber, a plunger rod, and stopper. Another exemplary medical device includes a syringe barrel having a plurality of air venting grooves associated with the sidewall of the barrel, a plunger rod and stopper. Also described is a medical device including a syringe barrel, plunger rod and stopper having a porous plug. Described is a medical device including a syringe barrel having a plurality of air venting grooves associated with the sidewall of the barrel and a porous membrane disposed over the air venting grooves, a plunger rod and stopper. Methods for filling a syringe barrel with a liquid are also provided.

INTEGRATED STRONTIUM-RUBIDIUM RADIOISOTOPE INFUSION SYSTEMS
Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer may include pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.
INFUSION SYSTEM WHICH UTILIZES ONE OR MORE SENSORS AND ADDITIONAL INFORMATION TO MAKE AN AIR DETERMINATION REGARDING THE INFUSION SYSTEM
In one step of a method for infusing an infusion fluid, the infusion fluid is pumped through a fluid delivery line of an infusion system. In another step, measurements are taken with at least one sensor connected to the infusion system. In an additional step, an air determination is determined with at least one processor. The air determination is related to air in the fluid delivery line. The air determination is based on the measurements taken by the at least one sensor. The air determination is further based on: (1) medication information regarding the infusion fluid or infusion information regarding the infusion of the infusion fluid; or (2) multi-channel filtering of the measurements from the at least one sensor or non-linear mapping of the measurements from the at least one sensor; and statistical process control charts applied to the multi-channel filtered measurements or applied to the non-linear mapped measurements.
HIGH RELIABILITY DRUG INFUSION DEVICE
