Abstract

An infusion set, comprising a base, and an inserter pivotally connected to said base, said inserter including a catheter movable from a first catheter position to a second catheter position, an introducer needle located within said catheter and movable between a first and second introducer needle positions, and an activation button, wherein when said button is moved from a first button position to a second button position, said catheter is moved from said first toward said second catheter position, said introducer needle is moved from said first toward said second introducer needle position, and said introducer needle is thereafter moved back toward said first introducer needle position, wherein in the second button position, the inserter is configured to fold substantially entirely within said base in the second inserter position.

Claims16

Dependent claims

An infusion set, comprising:

a base;
and
an inserter pivotally connected to said base, said inserter including:
a catheter movable from a first catheter position to a second catheter position;
an introducer needle located within said catheter and movable between a first introducer needle position and a second introducer needle position;
and
an activation button movable between first and second button positions, wherein when said activation button is moved from said first button position to said second button position, said catheter is moved from said first toward said second catheter position, said introducer needle is moved from said first toward said second introducer needle position to facilitate insertion of said catheter, and said introducer needle is thereafter moved back toward said first introducer needle position to store said introducer needle within said inserter with a free end of said catheter remaining disposed externally of said inserter and said base;
wherein in the first button position, the inserter is not configured to fold substantially entirely within said base in the first inserter position, and in the second button position, the inserter is configured to fold substantially entirely within said base in the second inserter position.

5 more elements

An infusion set, comprising:

a base;
and
an inserter pivotally connected to said base, said inserter including:
a body pivotable between first and second body positions;
a sleeve disposed in said inserter body and moves between first and second sleeve positions;
a catheter hub movable from a first catheter hub position to a second catheter hub position;
a catheter connected to said catheter hub, said catheter being disposed substantially entirely within said inserter body when said catheter hub is in said first catheter hub position and said catheter having a free end disposed externally of said inserter body and said base when said catheter hub is in said second catheter hub position;
an introducer hub movable between a first introducer hub position and a second introducer hub position;
an introducer needle located within said catheter and connected to said introducer hub, said introducer needle being disposed substantially entirely within said inserter body when said introducer hub is in said first introducer hub position and said introducer needle having a free end disposed externally of said inserter body and said base when said introducer hub is in said second introducer hub position;
a spring member biasing said introducer hub toward said first introducer hub position;
and
an activation button movable between first and second button positions, wherein:
when said activation button is in said first button position, said catheter hub and said introducer hub are in said first catheter hub position and said first introducer hub position, respectively;
when said activation button is between said first and second button positions, said sleeve moves from said first sleeve position to said second sleeve position, said spring biases said introducer hub, and said catheter hub and said introducer hub are moved toward said second catheter hub position and said second introducer hub position, respectively;
and
when said activation button is in said second button position, said catheter hub is in said second catheter hub position and said sleeve releases said introducer hub and said spring to retract said introducer hub toward said first introducer hub position via a spring force.

13 more elements

An infusion set, comprising:

a base;
and
an inserter pivotally connected to said base, said inserter including:
a body pivotable between first and second body positions;
a sleeve having first and second tabs, said sleeve being disposed in said inserter body and moves between first and second sleeve positions;
a catheter hub movable from a first catheter hub position to a second catheter hub position;
a catheter connected to said catheter hub, said catheter being disposed substantially entirely within said inserter body when said catheter hub is in said first catheter hub position and said catheter having a free end disposed externally of said inserter body and said base when said catheter hub is in said second catheter hub position;
an introducer hub movable between a first introducer hub position and a second introducer hub position;
an introducer needle located within said catheter and connected to said introducer hub, said introducer needle being disposed substantially entirely within said inserter body when said introducer hub is in said first introducer hub position and said introducer needle having a free end disposed externally of said inserter body and said base when said introducer hub is in said second introducer hub position;
and
an activation button movable between first and second button positions, wherein:
when said activation button is in said first button position, said catheter hub and said introducer hub are in said first catheter hub position and said first introducer hub position, respectively;
when said activation button is between said first and second button positions, said sleeve moves from said first sleeve position to said second sleeve position, and said introducer hub are moved toward said second catheter hub position and said second introducer hub position, respectively;
and
when said activation button is in said second button position, said catheter hub is in said second catheter hub position and said sleeve releases said introducer hub;
and further wherein:
said first and second tabs on said sleeve engage grooves in said inserter body to guide movement of said sleeve when said sleeve is moved from said first sleeve position to said second sleeve position by said activation button.
