Stabilizing fitting for an intravenous catheter
First Claim
1. A stabilizing fitting for securing an intravenous catheter to a patient'"'"'s skin comprising a laminar base member having a longitudinal axis, an upper surface and a lower surface, pressure-sensitive adhesive means on at least a part of said lower surface of said base member, a catheter hub-retaining cradle on said upper surface of said base member, said cradle having a forward end, a rearward end and resilient side walls substantially parallel to and symmetrically disposed on opposite sides of said longitudinal axis, said side walls being formed to receive and laterally locate a catheter hub pressed into said cradle, locating means associated with said cradle for maintaining said hub in position longitudinally of said axis with the catheter projecting substantially axially from said forward end of said cradle and a tab grip forming an extension of said base member rearwardly of said cradle, and further including a snap-over cover hinged to the upper edge of one of said side walls, a first latch member on said cover and a second latch member on the other of said side walls, said latch members being mutually engagable for holding the cover in place over a catheter hub fitting into the cradle.

Abstract
A stabilizing fitting for securely holding an intravenous catheter to a patient'"'"'s skin at a venipuncture site comprises a laminar base member with an adhesive lower surface and a catheter hub retaining cradle on its upper surface. After insertion of the catheter into a vein and connection to an infusion tube, the catheter hub is pressed into the cradle which locates the hub laterally and longitudinally and the fitting is dabbed onto the patient'"'"'s skin. Stabilization is then achieved by affixing criss-cross adhesive tapes over the assembly.

6. A stabilizing fitting for securing to a patient'"'"'s skin an intravenous catheter having a catheter hub of the type which includes a boss with an expanded transverse dimension, said fitting comprising:
-
a laminar base member having a longitudinal axis, an upper surface and a lower surface; pressure-sensitive adhesive means on said lower surface; a catheter hub-retaining cradle secured on said upper surface and having a bottom, an open top, a forward end, a rearward end and resilient sidewalls substantially parallel to and symmetrically disposed on opposite sides of said longitudinal axis proximate said forward end, said sidewalls being formed to resiliently engage and laterally locate the catheter hub pressed downwardly to the bottom of said cradle through said open top, said sidewalls being spaced to engage the catheter hub forwardly of said boss, said rearward end being defined by a rear support wall having a top edge which is recessed to a height above said bottom of said cradle to receive and support the catheter hub at a hub location rearward of said boss such that the catheter hub, when supported in said cradle, is disposed at a small angle relative to said upper surface wherein the hub diverges from said upper surface in a rearward direction, the sides of said cradle between said resilient sidewalls and said rear support wall being open to accomodate catheter hubs having expanded transverse dimensions; locating means comprising part of said cradle and disposed between said sidewalls and said support wall for maintaining the catheter hub in position longitudinally of said axis with the catheter projecting substantially axially from said forward end of said cradle; and a tab grip forming an extension of said base member extending from and substantially co-planar with said base member from a location on said base member outside the area on which said adhesive means is disposed, said tab grip being free of said adhesive means. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A stabilizing fitting for securing an intravenous catheter to a patient'"'"'s skin comprising a laminar base member having a longitudinal axis, an upper surface and a lower surface, pressure-sensitive adhesive means on at least a part of said lower surface of said base member, a catheter hub-retaining cradle on said upper surface of said base member said cradle having a forward end, a rearward end and resilient side walls substantially parallel to and symmetrically disposed on opposite sides of said longitudinal axis, said side walls being formed to receive and laterally locate a catheter hub pressed into said cradle, locating means associated with said cradle for maintaining said hub in position longitudinally of said axis with the catheter projecting substantially axially from said forward end of said cradle and a tab grip forming an extension of said base member rearwardly of said cradle, including gripping formations on internal surfaces of said side walls,
wherein said gripping formations comprise longitudinally-extending rib means on said internal surfaces; -
wherein said locating means includes an opening formed in each of said side walls; wherein said openings are dimensioned to receive and locate lateral wings extending from a catheter hub; wherein said openings are dimensioned to receive and locate a boss of a catheter hub; and wherein said side walls have rearward extensions of reduced height defining said upper surface means.
