Abstract
Abstract An apparatus for sterile insertion of a catheter or like device into an in-dwelling cannula. The catheter is sterilized after being sealed within the inserter apparatus and is retained within a sterile field during and following the insertion procedure. The inserter apparatus provides an effective seal around even a very small catheter to prevent loss of blood or other fluids from the in-dwelling cannula.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
217 words
A sterile inserter apparatus for sterile insertion of a catheter into an indwelling cannula comprising: a catheter; a housing having a larger bore therethrough than the outside diameter of said catheter; means for sealing around said catheter for preventing flow of blood or other fluid through said housing when said catheter is positioned in said bore; inserter end means for connecting said housing to said indwelling cannula; a flexible sleeve enclosing said catheter within a sterile field, one end of said sleeve being closed and the other end attached to the end of said housing opposite said inserter end means so that said catheter can be grasped through the walls of said sleeve and moved through the bore of said housing and into and through said indwelling cannula without voiding said sterile field; a sensing element supported at one end of said catheter adapted to be stored within the bore of said housing until said housing has been connected to said in-dwelling catheter, movement of the catheter through the walls of said sleeve resulting in movement of said sensing element thorugh and out the end of said cannula; and an electrical conductor supported within said catheter having one end connected to said sensing element and the other end extending through said closed end of said flexible bag.

Claim 3
Dependent Claim
147 words
A sterile inserter apparatus comprising: an elongated member; a housing having a bore sufficiently large to pass said elongated member; a sealed container surrounding said elongated member in a sterile field and having one end attached to said housing, said container being formed of a sufficiently flexible material that said elongated member can be grasped through the walls of said container and moved through the bore of said housing so that said container remains sealed while said elongated member is utilized to perform its normal functions; a sensing element supported at one end of said elongated member so that longitudinal movement of said member through the walls of said sealed container results in a corresponding movement of said sensing element; and an electrical conductor having one end connected to said sensing element and the other end extending out of said sealed container through a sealed portion thereof.
Claim 4
Dependent Claim
147 words
A sterile inserter apparatus comprising: an elongated member; a housing having a bore sufficiently large to pass said elongated member; a sealed container surrounding said elongated member in a sterile field and having one end attached to said housing, said container being formed of a sufficiently flexible material that said elongated member can be grasped through the walls of said container and moved through the bore of said housing so that said container remains sealed while said elongated member is utilized to perform its normal functions; a sensing element supported at one end of said elongated member so that longitudinal movement of said member through the walls of said sealed container results in a corresponding movement of said sensing element; and an electrical conductor having one end connected to said sensing element and the other end extending out of said sealed container through a sealed portion thereof.
Claim 5
Dependent Claim
194 words
A sterile inserter apparatus comprising: a catheter; a housing comprising a first and second member which screw together; said first housing member including, a septum piercing head having a frusto-conical tip terminating in a cylindrical surface of smaller diameter to form a barb-like configuration, an exteriorly threaded member at the end opposite said septum piercing head, and a central bore therethrough extending from said septum piercing head to said threaded member; said second housing member including an internally threaded bore extending partially therein and terminating in a bottom waLl, a central bore therethrough extending from said bottom wall to the opposite end of said second housing member, and an annular groove on the exterior wall of said housing; a flat resilient annular seal located within the internally threaded bore of said second housing member and engaged between the exteriorly threaded member of said first member and the bottom wall of said internally threaded bore of said second member; and a flexible, thin walled transparent sleeve container having an open end secured to said second housing member by an annular sealing member retained in said annular groove, said catheter being located within said sleeve container.
