Abstract: An injection system includes an injector head that is configured to control delivery of a designated fluid to a patient. The injector head includes a syringe interface along an active side of the injector head. The syringe interface has a receiving cavity that is configured to receive a syringe barrel. The injector head also includes an internal sensor. A magnetic switch has an external magnet outside of the injector head. The external magnet is operable to modify a magnetic field experienced by the internal sensor to activate the internal sensor.

Abstract: An injection system includes an injector head that is configured to control delivery of a designated fluid to a patient. The injector head includes a syringe interface along an active side of the injector head. The syringe interface has a receiving cavity that is configured to receive a syringe barrel. A side cover has a syringe opening therethrough. The side cover is sized and shaped to cover at least a portion of the active side of the injector head such that the receiving cavity and the syringe opening align with each other to form a port that receives the syringe barrel.

Abstract: A syringe barrel includes a barrel body having a passage extending along a longitudinal axis between a tip opening and a load opening. The passage is configured to permit a plunger to advance therethrough along the longitudinal axis for driving a liquid through the tip opening. The barrel body includes a base portion that is configured to operably engage an injection system. The base portion has a body surface that is shaped to form a light-propagating space alongside the body surface. The light-propagating space extends to reflective ramps of the body surface. The reflective ramps have predetermined sizes and positions to reflect light signals radially away from the barrel body.

Abstract: An infusion set check valve assembly includes a self-contained housing that defines inlet ports and an outlet port. The assembly also includes at least one check valve disposed within the self-contained housing between the outlet channel and at least one of the inlet ports. The at least one check valve is configured to open for a first fluid to flow from a first inlet to a patient line via an outlet channel while a second fluid also flows from a second inlet to the patient line via the outlet channel. The at least one check valve closes to prevent the first fluid from flowing to the patient line via the outlet channel while the second fluid flows to the patient line.

Abstract: An adapter for use with a syringe and a power injector includes an outer ring having a first end configured for passage of an end of a syringe having at least one flange. An inner ring is disposed coaxially within the outer ring. The inner ring has a first end including at least one flange slot. A magnet fixed relative to the inner ring such that when the syringe end is disposed in the outer ring and the at least one flange engages the at least one flange slot, rotation of the syringe causes rotation of the inner ring and magnet relative to the outer ring.

Abstract: A check valve assembly is configured to couple to a first container that retains a first fluid and a second container that retains a second fluid. The check valve includes a fluid inlet housing including a first fluid inlet port defining a first fluid inlet channel, and a second fluid inlet port defining a second fluid inlet channel. A fluid outlet housing is coupled to the fluid inlet housing. The fluid outlet housing includes a fluid outlet port defining a fluid outlet channel. A first diaphragm is seated over the first fluid inlet channel. At least a portion of the first diaphragm is configured to unseat over the first fluid inlet channel to allow the first fluid to pass from the first fluid inlet channel into the fluid outlet channel. A second diaphragm is seated over the second fluid inlet channel. At least a portion of the second diaphragm is configured to unseat over the first fluid inlet channel to allow the second fluid to pass from the second fluid inlet channel into the fluid outlet channel.

Abstract: An adapter for a medical receptacle having an internally threaded skirt with an outside diameter and an inside diameter, and a post within the skirt, includes a proximal end portion having a threaded surface including at least one thread configured to threadingly engage a threaded interior of a skirt of a medical receptacle, and a distal end portion having a surface portion and a generally cylindrical recess. The proximal end portion includes a tapered recess defined by a wall, a chamfer, and a seat and the surface portion includes a gripping mechanism. A conduit is positioned between the tapered recess and the generally cylindrical recess such that the conduit is in fluid communication with both the recess and the generally cylindrical recess.
