ABSTRACT:
A device for transmitting intravenous fluids between a patient and an external reservoir is provided with a retractable needle for penetrating an intravenous fluid port or for directly penetrating the skin of the patient. The retractable needle renders the device safe for disposal after use. The device comprises a housing for holding the needle in a projecting configuration, a needle retainer for holding the needle in the projecting configuration against a rearward bias exerted by a spring, and an actuating member slidably positioned in the housing for releasing the needle retainer from the needle. An intravenous tubing connector is positioned to extend from the housing to provide a fluid connection between the needle and the external reservoir.
