Abstract
Certain embodiments provide multi-medicament or single medicament infusion systems for preventing the cross-channeling or improper delivery of medicaments. The system may include one or more of an infusion pump, medicament cartridges, cartridge connectors, a multi-channel fluid conduit, and an infusion set. The medicament cartridges may be sized and shaped differently such that the medicament reservoirs can only be inserted into the pump under selected configurations.
Claims29
A cartridge connector comprising:
- a body comprising:
- a needle;
- a lower surface portion extending circumferentially outwardly from the needle, the lower surface comprising a bowl-shaped concavity and a surrounding lip, wherein the needle protrudes out of and extends away from the bowl-shaped concavity;
- a shroud extending axially away from a circumference of the lower surface portion and configured to receive and fit over a portion of a first medicament cartridge that is configured to hold a first medicament;
- wherein the lower surface portion is located within the shroud;
- wherein the needle extends axially from the lower surface portion and within the shroud;
- wherein the body comprises a projection extending axially upwardly from an upper surface of the body, the projection comprising a fluid outlet;
- and
- wherein the body is configured to receive the first medicament through the needle and to deliver the first medicament out of the body from the fluid outlet of the projection, the needle and the fluid outlet of the projection being in fluidic communication and providing a fluid path through the body;
- a knob portion comprising:
- a receptacle section, the receptacle section of the knob portion configured to extend over and receive at least a portion of the projection of the body;
- a fluid inlet located within the receptacle section, the fluid inlet of the knob portion being configured to receive the first medicament;
- and
- a fluid outlet, the fluid outlet of the knob portion being configured to deliver the first medicament to a position outside the cartridge connector;
- wherein the cartridge connector comprises an interstitial space located between the projection of the body and the receptacle section of the knob portion and a flexible membrane located within the interstitial space, the flexible membrane extending over at least a portion of the projection of the body and being configured to allow fluid to pass from the fluid outlet of the projection and into the fluid inlet of the knob portion only after a threshold fluid pressure of the first medicament is reached;
- and
- wherein the cartridge connector is configured to engage a first pump receptacle of an infusion pump.
