Abstract

An infusion system comprises an infusion set ( 30 ) with one or more advanced features including tube set strain relief ( 10 ), infusion pumps having heat exchange abilities and two-direction pumping abilities ( 100 ), Piezo pump devices ( 200 ), reservoirs ( 220, 240 ) made from expanded tubing, and oil impregnated pump plungers ( 302 ). An exemplary strain relief ( 10 ) includes an adhesive layer ( 12 ) such as pressure sensitive adhesive (PSA) secured to a base ( 14 ). The base ( 14 ) rotatably receives a pin ( 18 ) of a tube holder ( 16 ). The pin ( 18 ) is captured within an opening ( 22 ) of the base ( 14 ) to allow 360 degree rotation of the tube holder ( 16 ).

First claim

The invention claimed is:

1. An apparatus comprising:
a tube having at least one tube segment, a distal end secured to an infusion set and a proximal end secured to an infusion pump:
a securing member for releasably securing said tube segment, said tube segment being a portion of said at least one tube between said distal end of said tube and said proximal end of said tube; the securing member comprising a circular section of flexible material having an open portion, the securing member having a longitudinal axis, and wherein the securing member is adapted to deflect in a direction around the longitudinal axis to receive the tube segment and contract to secure the tube segment once received; and
a securing member base comprising an adhesive layer for adhesively securing said securing member base to a skin surface and a planar top surface opposite the adhesive layer, wherein said securing member is coupled with said securing member base; wherein said securing member is coupled to said securing member base with a pin received within the securing member base and captured within an opening of the securing member base, the opening having a narrow portion on a top surface of the securing member base, and a wide portion on a bottom surface of the securing member base, and where the pin conforms in shape to the opening to permit 360 degree free rotation of the securing member about the securing member base, and wherein the pin extends in a direction perpendicular to the planar top surface such that when secured to the skin with the adhesive layer, the securing member is rotatable about an axis normal to said planar top surface and to the skin surface.

2. An apparatus as claimed in claim 1 , wherein said securing member comprises an adhesive cover to adhesively secure said tube segment to said securing member.
