Abstract
Abstract A base member having a side surface and a bottom surface is provided. First and second ports are formed in the side surface which are interconnected by a channel in the base member. An intravenous system tube may be passed through the first port and channel and out the second port to provide for reversal of fluid flow in the tube with respect to the direction of fluid flow in the tube at the first port. The channel is formed to preclude kinking of the tube. Alternately, intravenous fluid system tubing may be adapted to the first and second ports. The tubing connects to an intravenous fluid supply and to a catheter apparatus. Means may be adapted to a top surface of the base member to permit the injection of medications into the fluid passing through the channel or the tubing in the channel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
122 words
An intravenous tube loop device comprising: a. a base member having (1) a side surface and (2) a bottom surface for positioning adjacent the skin of a patient; b. a first port formed in said side surface; c. first connector means to removably connect intravenous fluid supply tubing to said first port; d. a second port formed in said side surface; e. second connector means to removably connect said second port to an intravenous catheter apparatus; and f. channel means to interconnect said first port and said second port which permits the flow of fluids therebetween and which changes the direction of the flow of said fluids with respect to the direction of the flow of said fluids at said first port.
Claim 2
Dependent Claim
122 words
An intravenous tube loop device comprising: a. a base member having (1) a side surface and (2) a bottom surface for positioning adjacent the skin of a patient; b. a first port formed in said side surface; c. first connector means to removably connect intravenous fluid supply tubing to said first port; d. a second port formed in said side surface; e. second connector means to removably connect said second port to an intravenous catheter apparatus; and f. channel means to interconnect said first port and said second port which permits the flow of fluids therebetween and which changes the direction of the flow of said fluids with respect to the direction of the flow of said fluids at said first port.
Claim 3
Dependent Claim
33 words
The intravenous tube loop device of claim 1 wherein the direction of said fluid flow at said second port is substantially reversed with respect to the direction of flow at said first port.
Claim 4
Dependent Claim
36 words
The intravenous tube loop device of claim 1 wherein said base member has a top surface with means adapted thereto in communication with said channel to permit injection of medications into said fluids in said channel.
Claim 5
Dependent Claim
41 words
The intravenous tube loop device of claim 1 wherein said channel is circular in cross section and U shaped in projection, and wherein said bottom surface is concave in axial cross section to facilitate positioning on the arm of a patient.
Claim 6
Dependent Claim
72 words
The tube loop device of claim 1 wherein said first connector means is comprised of coacting male and female connectors alternately and selectively adapted to said base member in communication with said first port and to said intravenous tubing and said second connector means is comprised of coacting male and female connectors alternately and selectively adapted to said base member in communication with said second port and to said intravenous catheter apparatus.
Claim 7
Dependent Claim
58 words
The intravenous tube loop device of claim 1 wherein said first connector means is a cylindrical extension secured to said first port and adapted to removably receive intravenous tubing thereover, and wherein said second connector means is a cylindrical extension secured to said second port and adapted to removably connect to the hub of said intravenous catheter apparatus.
Claim 8
Dependent Claim
62 words
The intravenous tube loop device of claim 6 wherein said first connector means includes glue means to fixedly secure said intravenous fluid supply tubing to said first port, and wherein said second connector means is intravenous fluid tubing fixedly secured by glue means at its first end to said second port and removably adaptable to said catheter apparatus at its second end.
Claim 9
Dependent Claim
31 words
The intravenous tube loop device of claim 7 wherein said base member is constructed of plastic and sized to be about 1/2 inch wide, 3/8 inch high and 5/8 inch long.
Claim 10
Dependent Claim
50 words
The intravenous tube loop device of claim 1 wherein said first port, second port and channel are sized in cross section to permit said intravenous fluid supply tube to be passed through said first port and said channel and out said second port for said connection to said catheter apparatus.
Claim 11
Dependent Claim
40 words
The intravenous catheter apparatus of claim 9 wherein said channel is circular in cross section and U shaped in projection, and wherein said bottom surface is concave in axial cross section to facilitate positioning on the arm of a patient.
Claim 12
Dependent Claim
53 words
The intravenous tube loop device of claim 10, wherein said base member has a top surface constructed as a removable lid, so that when said lid is removed said first and second ports and said channel are exposed to permit placement of said tubing through said first and second ports and said channel.
Claim 13
Dependent Claim
163 words
In combination with an intravenous therapy system which includes (1) a supply of intravenous fluid, (2) a catheter apparatus for injecting said fluids into a blood vein of a patient, and (3) tubing interconnecting said supply of intravenous fluid and said catheter apparatus, a tube loop device comprising: a. a base member having (1) a side surface and (2) a bottom surface for positioning adjacent the skin of a patient; b. a first port formed in said side surface; c. first connector means to removably connect intravenous fluid supply tubing to said first port; d. a second port formed in said side surface; e. second connector means to removably connect said second port to an intravenous catheter apparatus; and f. channel means to interconnect said first port and said second port which permits the flow of fluids therebetween and which changes the direction of flow of said fluids with respect to the direction of the flow of said fluids at said first port.
Claim 14
Dependent Claim
163 words
In combination with an intravenous therapy system which includes (1) a supply of intravenous fluid, (2) a catheter apparatus for injecting said fluids into a blood vein of a patient, and (3) tubing interconnecting said supply of intravenous fluid and said catheter apparatus, a tube loop device comprising: a. a base member having (1) a side surface and (2) a bottom surface for positioning adjacent the skin of a patient; b. a first port formed in said side surface; c. first connector means to removably connect intravenous fluid supply tubing to said first port; d. a second port formed in said side surface; e. second connector means to removably connect said second port to an intravenous catheter apparatus; and f. channel means to interconnect said first port and said second port which permits the flow of fluids therebetween and which changes the direction of flow of said fluids with respect to the direction of the flow of said fluids at said first port.
