ABSTRACT:
An I.V. needle carrier assembly is disclosed which includes a delta-shaped base plate and an I. V. needle carrier-receiving barrel secured to the base plate and extending along the axis of symmetry thereof, so that the forward open end of the barrel resides at the apex of the delta. An I.V. needle carrier is slidingly received within the barrel and means are provided for sliding the carrier between a rearward position at which the needle tip is axially retracted within the barrel, and a forward position at which the needle tip is fully extended through the barrel front open end, whereby the needle may be inserted into the blood vessel of a patient. Adhesion means are affixed to the upper surfaces of the base plate at alternate sides of the barrel. These means include portions extendable beyond the lateral perimeter of the delta for anchoring the plate to the skin of the patient upon the needle being received into the blood vessel. The barrel includes a longitudinally extending slot through its surface and a pair of detents intersecting the slot. The needle carrier includes a grasping projection extending from the carrier and through the barrel slot to enable grasping by the user of the assembly during emplacement of the same. Axial movement of the grasping portion enables the user to displace the needle carrier between its rearward and forward positions, and the grasping portion may be rotated into the detents to lock the needle carrier at its rearward or forward position.
