Filed:

Jan 26, 2007

Appl. No.:

11/627857

Inventors:

Matthew Dickson Reavill - Plainfield IL, US

International Classification:

A61M 31/00
A61M 5/20
A61M 5/178
A61M 5/00
A61M 25/00

US Classification:

604510, 604500, 604506, 604507, 604508, 604156, 604158, 604159, 60416401, 60416402, 60416701, 60416703, 604171, 604264, 604523, 604528

Abstract:

A long catheter can be inserted into a patient while eliminating the need for a sterile field by incorporating the long catheter into an infusion tubing and carrying it in with the infusion. The long catheter has a structure that prevents it from leaving the infusion tubing when fully extended and therefore becomes a connector for fluids to transfer down the long catheter by infusion through the infusion tubing. Use of an adjustable seat connector allows the long catheter to be stopped at varying points during insertion and even to allow the long catheter to be reversed by pulling suction on the infusion tubing and retracting the long catheter back into the infusion tubing. The long catheter also remains within the sterile confines of the infusion tubing and therefore is prevented from becoming contaminated.

Appl. No.:

11/550206

Inventors:

Matthew D. Reavill - Plainfield IL, US

International Classification:

A61M 1/00
A61N 1/30

US Classification:

604 27, 604 21, 604 28

Abstract:

A method and apparatus for inserting a catheter into a patient and measuring and approximating its distal end position within the body facilitate catheter insertion and improve accuracy and control. By wrapping a long infusion catheter with an outer coating, the catheter can be guided into a vein or vessel by pulling on the outer coating and forcing its separation in a Y-shaped separation housing anchored close to the insertion point. Since there is no need for a guidewire or stylet and the outer coating acts as a sterile peel package, the catheter can be placed while infusing and maintain its own closed sterile environment during insertion.
