Abstract
An infusion set (10,12) comprises a first part (10) housing a pump and control means and a second part (12) housing a replaceable infusate reservoir (14) with an integral infusion line (16). An anti-freeflow sliding member (26) has an opening (28) through which the infusion line (16) passes, and is slidable between a first open position and a second closed position by detaching the parts.
Claims21
An infusion set comprising a first part, a second part defining a cavity for housing a removable infusate reservoir and infusion line, the parts being releasably attachable together, and a closure member slidably mounted on the second part for closing the infusion line, the closure member defining an opening for passage of the infusion line therethrough, the closure member being operable, by detachment of the parts between a first, open infusion line position wherein the infusion line passes through a portion of the opening of dimension great enough to allow flow of infusate through the infusion line, and a second, closed infusion line position wherein the infusion line passes through a portion of the opening having a dimension sufficiently less than the diameter of the infusion line to occlude the infusion line.
An infusion set comprising:
- a first pump part including an infusion pump;
- a second reservoir part releasably attached to the first pump part including an infusate reservoir and at least a portion of an infusion line;
- and
- an infusion line closure member positionable between an open position permitting flow through the infusion line when the first pump part and the second reservoir part are attached and a second closed position restricting flow through the infusion line when the first pump part and the second reservoir part are detached.
An infusion set comprising a first part, a second part for containing an infusate reservoir and infusion line, the parts being releasably attachable together, and means for closing the infusion line, the closure means being slidably mounted on the second part between a first, open infusion line position and a second, closed infusion line position operable by detachment of the parts to close the infusion line, wherein the closure means has a tongue with a detent arranged to engage a projection on the first part to slide the closure means from the first to the second position as the parts are pulled apart and further arranged to release the closure means when the parts are fully detached, and further wherein the infusion line passes through an opening in the closure means and the closure means is further mounted such that in the first position the infusion line passes through a portion of the opening of dimension great enough to allow flow of infusate through the infusion line and in the second position the infusion line passes through a portion of the opening having a dimension sufficiently less than the diameter of the infusion line to occlude the infusion line.
An infusion set comprising:
- a first pump part including an infusion pump;
- a second reservoir part releasably attached to the first pump part, the second reservoir part defining a cavity to house a removable infusate reservoir and at least a portion of an infusion line;
- and
- an infusion line closure member positionable between an open position permitting flow through the infusion line when the first pump part and the second reservoir part are attached and a second closed position restricting flow through the infusion line when the first pump part and the second reservoir part are detached.
