Abstract

Abstract An intravenous infusion device includes a first wing member attached to a needle. A flexible conduit for supplying fluid to the needle is connected thereto via an intermediate sleeve of the same material as the conduit. A tiedown wing is removably attached to and movable along the conduit. Both the wing portion attached to the needle and the movable tiedown wing are composed of a synthetic thermoplastic eleastomer, preferably a block copolymer of styrene and butadiene.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 16 words
The apparatus according to claim 1 wherein the member is molded from a synthetic thermoplastic material.
Claim 2
Dependent Claim 19 words
The apparatus according to claim 2 wherein the member is molded from a block copolymer of styrene and butadiene.
Claim 3
Dependent Claim 36 words
The apparatus according to claim 1 wherein the member is further characterized by a layer of adhesive on the bottom surface of each wing for use in securing the member to the skin of the patient.
Claim 4
Dependent Claim 19 words
The apparatus according to claim 4 wherein the adhesive layers are protected by removable laminating sheets prior to use.
Claim 5
Dependent Claim 300 words
An intravenous infusion device comprising: an elongate, hollow needle having a substantially sharp distal end and a blunt proximal end, and adapted for insertion under the skin and into a vein of a patient; a holding means for securing the said device to the skin of a patient comprising a first member including a relatively thick hub surrounding and fixedly secured to the needle at a point between the distal and proximal ends thereof and a pair of relatively thin wings extending outwardly from the opposite sides of the hub and having normally coplanar bottom surfaces adapted for engagement with the skin of the patient; a supply tube connected at one end in fluid communication with the proximal end of the needle and including means at the opposite end for connection to a source of fluid; and a second securing member including a relatively thick hub having a passageway formed through it characterized by an inside diameter normally substantially equal to the outside diameter of the supply tube and a pair of relatively thin wings extending outwardly from the opposite sides of the hub and having normally coplanar bottom surfaces for engagement with the skin of the patient; said passageway in the hub of the second member communicating with the bottom surfaces of the wings of the member by means of a slot normally substantially narrower than the outside diameter of the supply tube to provide a hollow means that when the slot is opened to receive the supply tube in response to bending of the wings of the second member upwardly and inwardly toward the hub and is closed to securely clamp the supply tube in the passageway of the hub in response to release of the wing when they are extended substantially flat in their skin engaging position.
Claim 6
Dependent Claim 22 words
The intravenous infusion device according to claim 6 wherein the second member comprises a unitary structure molded from a synthetic thermoplastic material.
Claim 7
Dependent Claim 22 words
The intravenous infusion device according to claim 7 wherein the second member is molded from a block copolymer of styrene and butadiene.
Claim 8
Dependent Claim 59 words
The intravenous infusion device according to claim 6 wherein the second member is further characterized by an adhesive layer formed on the bottom surface of each wing and a protective layer initially overlying each adhesive layer, whereby upon removal of the protective layers the wings of the second member may be adhesively secured to the skin of the patient.
Claim 9
Dependent Claim 178 words
Apparatus for securing a tubular member to the skin of a patient comprising: a hub having a longitudinally extending passageway formed through it; said passageway in the hub being characterized by an interior configuration substantially congruent to the exterior configuration of a portion of a tubular member; a pair of wings extending outwardly from the opposite sides of the hub and comprising normally coplanar bottom surfaces for engagement with the skin of the patient; and said passageway in the hub intersecting the plane of the bottoM surfaces of the wings to define a slot which is normally substantially narrower than said portion of the tubular member; said wings and hub having sufficient resiliency to permit upward and inward bending of the wings to open the slot and thereby facilitate positioning of said portion of the tubular member in the passageway formed in the hub and thereafter to return the wings substantially to the normal outwardly extending patient skin engaging positions thereby closing the slot and clamping said portion of the tubular member in the passageway of the hub.
Claim 10
Dependent Claim 22 words
The apparatus according to claim 10 wherein the hub and the wings comprise a unitary structure molded from a synthetic thermoplastic material.
Claim 11
Dependent Claim 18 words
The apparatus according to claim 11 wherein the synthetic thermoplastic material comprises a copolymer of styrene and butadiene.
Claim 12
Dependent Claim 30 words
The apparatus according to claim 10 further characterized by adhesive layers formed on the bottom surfaces of the wings for adhesively securing the apparatus to the skin of the patient.
Claim 13
Dependent Claim 18 words
The apparatus according to claim 13 wherein each adhesive layer is initially protected by a removable, nonadhesive layer.
