A lid for closing an open ended blood chamber is provided. The lid is a one piece device forming an inlet to the blood chamber. The one piece device includes a filter media spaced apart from the inlet and wherein blood passing through the inlet passes through the filter media upon entry into the blood chamber. The filter media filters gross particulate from the blood passing therethrough. The one piece device further includes a vent port with an associated vent port cover to allow air separated to vent from the blood chamber.

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.

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.

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.

A fluid handling device, such as a needlefree access device, includes a housing having an inlet and an inlet channel; and a flow control member comprising a combination outlet, biasing and piston member. The flow control member includes a piston section moveable between a closed position in which the piston section is in the inlet channel and an open position in which the piston section is inside the housing below the inlet channel but allows fluid to flow through the inlet channel; a biasing section connected to the piston section that normally biases the piston section into the inlet channel; and an outlet section connected to the biasing section having an outlet fitting in fluid communication with the inside of the housing. The piston section, biasing section and outlet section are connected together such that they can be handled as one piece when assembled with the housing to make the needlefree access device. The access device can be configured as a Y-site access device, or used on other devices such as an IV bag. A check valve made by a two shot molding process is also disclosed.
