An infusion pump assembly includes a locking tab and a pump barrel inside a pump barrel housing, where the pump barrel accommodates a reservoir assembly. The reservoir assembly includes a reservoir and a plunger rod. The infusion pump assembly also includes a locking disc at a terminus of the pump barrel. The locking disc includes a clearance hole for the plunger rod. The locking disc also includes at least one locking tab notch in close proximity with the locking tab. The locking tab is in moveable engagement with the locking tab notch, and the reservoir moves the locking tab from a locked position to an unlocked position when the plunger rod is inserted through clearance hole. The locking disc rotates upon torque being applied to the reservoir assembly, the locking disc rotating from a non-loaded position to a loaded position with respect to the plunger rod and a drive screw.

An apparatus for shielding medical personnel from radioactive materials being administered to a patient in need thereof, including a radioactive syringe shield and a radioactive fluid pump shield. The radioactive syringe shield includes a syringe main body, and syringe shields proximal and distal ends each configured to attach to opposite ends of the syringe shield main body in a threaded male/female connection. Together, the syringe shield main body, and proximal and distal ends are configured to contain therewithin a medical syringe containing radioactive medical fluid. The radioactive fluid pump shield is a shielded box configured to contain the fluid pump and has top and front portions pivotally attached to adjacent portions to allow selective access to the fluid pump.

A system is disclosed for inserting a pharmaceutical cartridge into a delivery device. Optionally the cartridge is inserted in an arbitrary orientation. Optionally, the system reorients the cartridge to a locked orientation. For example, a driver applies a torque to the cartridge to cause the reorienting. For example, said torque rotates the cartridge around an axis thereof until the cartridge reaches the locked orientation. Optionally, when the cartridge reaches the locked orientation an interference element on the cartridge interlocks with a complementary interference element on the delivery device to lock the cartridge in the locked orientation. Optionally when the cartridge is locked in the second orientation, the torque causes discharge the pharmaceutical.

A medical pump, comprising: a fluid housing having a plurality of intake openings, sealed by at least one intake valve, and an outlet opening sealed by an outlet valve; a piston which is sealing the fluid housing and connected to a drive mechanism, the drive mechanism pulls the piston to draw fluid from one of the plurality of intake openings and pushes the piston to discharge the fluid into the outlet opening; and a selecting valve enclosing at least two tubes, each providing fluid to one of the plurality of intake openings, wherein the selecting valve closes one of the at least two tubes while opening another of the at least two tubes.

A method, computer program product, and infusion pump assembly for determining a first rate-of-change force reading that corresponds to the delivery of a first dose of an infusible fluid via an infusion pump assembly. At least a second rate-of-change force reading is determined that corresponds to the delivery of at least a second dose of the infusible fluid via the infusion pump assembly. An average rate-of-change force reading is determined based, at least in part upon the first rate-of-change force reading and the at least a second rate-of-change force reading.

A reader system for reading information on at least one identification tag associated with a syringe connected to a fluid injector has a detector and a background screen spaced apart from the detector such that at least one of the at least one identification tags is positioned in an optical path between the detector and the background screen when the syringe is connected to the fluid injector. The reader system further has an illumination system configured for illuminating at least a portion of the background screen. The detector is configured for detecting and decoding the at least one identification tag. Methods for reading information on at least one identification tag associated with a syringe are also described.

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an interior surface defining an enclosed space, and an exterior surface releasably attachable to a patient. A container may be disposed in the enclosed space and include a reservoir containing a drug and a stopper. A drive assembly may also be disposed in the enclosed space and configured to move the stopper through the reservoir to expel the drug from the reservoir. The drive assembly may include a rotational power source and a gear module. The gear module may include a mounting plate and a plurality of gears rotatably connected to the mounting plate. Furthermore, the mounting plate may be separate from the main housing.

Disclosed herein is a syringe pump module with a non-decoupling drive mechanism and motor actuation mechanism to configured to bidirectionally move the non-decoupling drive mechanism.
