A pre-slit injection site (34) includes a housing (40) with a flow path therethrough. A first end (42) of the housing (40) carries a pre-slit septum (52). One form of a blunt cannula (98), usable with the injection site (34), carries a locking member (100). When the pre-slit injection site (34) slidably receives the blunt cannula (98), the locking member (100) latches to the injection site (34) and creates a mechanically coupled unit. Another form of the cannula (280) includes a tube having a tapered distal end region (298) and having elongate discharge slots (294) for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post (330), an annular barb (394), and axially oriented grooves (268). A blood sampling system utilizing an in-line pre-slit injetion site (492) and a shielded blunt cannula (512). An adapter for transferring fluids from a syringe with a blunt cannula to an evacuated tube, including a pre-slit injection site (554) and a shroud covered needle (556) with a rubber sleeve.

The present invention provides a modular system for mounting one or more medical devices on an IV pole at a patient's bedside. The system comprises a support plate, and at least one modular interconnection receptacle adapted to be detachably mounted on the support plate and adapted to receive a medical device. In one embodiment, the interconnection receptacle has electrical connection means serving as an electrical conduit between the medical device and a monitor. The means for attaching the medical device to the interconnection receptacle has a greater retention force than the means for attaching the interconnection receptacle to the support plate. Thus, in response to a threshold force on the patient line connected to the medical device, the interconnection receptacle breaks free of the support plate while the medical device remains attached to the interconnection receptacle. This maintains fluid connection to the patient and electrical connection to a monitor in the case of a medical device, such as a pressure transducer.
