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