Abstract
Abstract This invention provides a vascular stabilizer in which a base plate that has a major medial longitudinal aperture or slot is adapted to be positioned so that the edges of the slot embrace a vein. The slot is defined by an arched connector or hood portion to rigify the slot and to protect a needle-type catheter in inserted position and means are provided to readily secure the base plate member to the patient as well as exerting mild pressure on either side of the vein to be infused.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
An intravenous vascular stabilizer comprising a substantially rigid rectangular base plate having a substantially medial longitudinal aperture defined by edges that closely embrace a vascular strand with an open bracket means terminating one end thereof and a substantially rigid elongated, inverted U-shaped bubble hood means overlying the other end thereof, said hood means having junction means along the sides thereof connecting the edges of said aperture along a substantial length thereof to rigidfy the edges of the longitudinal aperture whereby the open bracket means will snugly hold an intravenous needle collar and the bubble hood will cover a portion of the needle and vasculature and will engage the raised vein when pressed from above.
Claim 2
Dependent Claim
114 words
An intravenous vascular stabilizer comprising a substantially rigid rectangular base plate having a substantially medial longitudinal aperture defined by edges that closely embrace a vascular strand with an open bracket means terminating one end thereof and a substantially rigid elongated, inverted U-shaped bubble hood means overlying the other end thereof, said hood means having junction means along the sides thereof connecting the edges of said aperture along a substantial length thereof to rigidfy the edges of the longitudinal aperture whereby the open bracket means will snugly hold an intravenous needle collar and the bubble hood will cover a portion of the needle and vasculature and will engage the raised vein when pressed from above.
Claim 3
Dependent Claim
42 words
An intravenous vascular stabilizer as in claim 1 wherein the open bracket means is formed with a taper to frictionally grasp the tapered collar portion of the needle and is oriented at an acute angle to the planar extent of the base.
Claim 4
Dependent Claim
23 words
An intravenous vascular stabilizer as in claim 1 wherein the base has affixed thereto a plurality of clip means for fastening intravenous tubing.
Claim 5
Dependent Claim
21 words
An intravenous vascular stabilizer as in claim 1 wherein flexible strap members extend laterally from the base to encircle a limb.
Claim 6
Dependent Claim
27 words
An intravenous vascular stabilizer as in claim 1 wherein the edges of said aperture at the junction with said hood means are provided with downwardly extending ribs.
Claim 7
Dependent Claim
16 words
An intravenous vascular stabilizer as in claim 1 wherein the base plate and hood are transparent.
Claim 8
Dependent Claim
100 words
An intravenous vascular stabilizer comprising a substantially rigid rectangular base plate having a substantially medial longitudinal aperture defined by edges that closely embrace a vascular strand with an open bracket substantially rigid inverted U-shape bubble hood means overlying substantially the entire length of said aperture, the sides of said hood means connected to the edges of said aperture along a major length thereof to rigify the edges of the longitudinal aperture whereby the bubble hood will cover a substantial portion of the longitudinal aperture and the edges of the longitudinal aperture will engage the raised vein when pressed from above.
Claim 9
Dependent Claim
100 words
An intravenous vascular stabilizer comprising a substantially rigid rectangular base plate having a substantially medial longitudinal aperture defined by edges that closely embrace a vascular strand with an open bracket substantially rigid inverted U-shape bubble hood means overlying substantially the entire length of said aperture, the sides of said hood means connected to the edges of said aperture along a major length thereof to rigify the edges of the longitudinal aperture whereby the bubble hood will cover a substantial portion of the longitudinal aperture and the edges of the longitudinal aperture will engage the raised vein when pressed from above.
