Abstract
Removable tubing cartridges are described herein. A removable tubing cartridge includes an elongated cartridge body. The cartridge body further includes an upper lip disposed about the upper end of the cartridge body, wherein the upper lip extends axially away from the cartridge body. The cartridge can further include at least one lower fastener disposed about the lower end of the cartridge body, wherein the upper lip and the at least one lower fastener are configured to cooperatively align the cartridge body within the infusion pump. The cartridge can further include an upper tubing adapter cavity and a lower tubing adapter cavity that are configured to cooperatively align the pump segment tubing relative to the cartridge body.
Claims18
A removable tubing cartridge for aligning a pump segment tubing within an infusion pump, the cartridge comprising:
- an elongated cartridge body comprising an upper end and a lower end;
- an upper lip disposed about the upper end of the cartridge body, wherein the upper lip extends axially away from the cartridge body in a first direction;
- at least one lower fastener disposed about the lower end of the cartridge body,
- wherein the at least one lower fastener extends axially away from the cartridge body in the first direction and the upper lip and the at least one lower fastener are configured to cooperatively align the cartridge body within the infusion pump;
- an upper tubing adapter cavity formed in the upper lip, the upper tubing adapter cavity having a mating profile defining an opening of the upper tubing adapter cavity to receive an upper tubing adapter, wherein the mating profile defines a generally semi-circular mating profile extending from an edge of the upper lip, wherein the edge of the upper lip is configured to engage at least one upper pin of the infusion pump, and the semi-circular mating profile extends from the edge of the upper lip toward the cartridge body;
- and
- a lower tubing adapter cavity formed in the cartridge body, wherein the lower tubing adapter cavity is longitudinally spaced apart from the upper tubing adapter cavity and the upper tubing adapter cavity and the lower tubing adapter cavity are configured to cooperatively align the pump segment tubing relative to the cartridge body,
- wherein the upper lip has a spring bias to frictionally engage the upper tubing adapter within the mating profile.
A removable tubing cartridge assembly for use with an infusion pump, the cartridge assembly comprising:
- an elongated cartridge body comprising an upper end and a lower end;
- an upper lip disposed about the upper end of the cartridge body, wherein the upper lip extends axially away from the cartridge body in a first direction;
- an upper tubing adapter cavity formed in the upper lip, the upper tubing adapter cavity having a mating profile defining an opening of the upper tubing adapter cavity, wherein the mating profile defines a generally semi-circular mating profile extending from an edge of the upper lip, wherein the edge of the upper lip is configured to engage at least one upper pin of the infusion pump, and the semi-circular mating profile extends from the edge of the upper lip toward the cartridge body;
- a lower tubing adapter cavity formed in the cartridge body;
- a pump segment tubing comprising a first end and a second end, wherein the pump segment tubing extends from about the upper tubing adapter cavity to about the lower tubing adapter cavity;
- an upper tubing adapter coupled to the first end of the pump segment tubing, wherein the upper tubing adapter is configured to be inserted into the opening of the upper tubing adapter cavity and engage with the upper tubing adapter cavity;
- and
- a lower tubing adapter coupled to the second end of the pump segment tubing, wherein the lower tubing adapter is configured to engaged with the lower tubing adapter cavity, aligning the pump segment tubing longitudinally from the upper tubing adapter cavity to the lower tubing adapter cavity,
- wherein the upper lip has a spring bias to frictionally engage the upper tubing adapter within the mating profile.
A method to install a removable tubing cartridge within an infusion pump, the method comprising:
- introducing an upper end of the cartridge to the infusion pump;
- engaging an upper lip of the cartridge with the infusion pump, wherein an upper tubing adapter cavity is formed in the upper lip, the upper tubing adapter cavity having a mating profile defining an opening of the upper tubing adapter cavity, wherein the mating profile defines a generally semi-circular mating profile extending from an edge of the upper lip, wherein the edge of the upper lip is configured to engage at least one upper pin of the infusion pump, and the semi-circular mating profile extends from the edge of the upper lip toward a cartridge body;
- frictionally engaging an upper tubing adapter within the mating profile via a spring bias of the upper lip;
- introducing a lower end of the cartridge to the infusion pump;
- and
- engaging at least one lower fastener of the cartridge with the infusion pump.
