Abstract
An infusion cartridge for use with an ambulatory infusion system can be provided with a preattached infusion set to eliminate potential leakage, potential snagging and other inconveniences from tubing connectors. The infusion cartridge can include a rigid housing, a collapsible fluid reservoir within the housing and a dispense mechanism for drawing fluid from the reservoir and sending it out an outlet port. A length of tubing can be fixedly attached to the outlet port in fluid communication with the outlet port. The length of tubing can extend as a unitary construct from the outlet port to a connector that connects to a cannula for delivering fluid from the reservoir to a user.
Claims19
An ambulatory infusion system comprising:
- an infusion cartridge it a rigid housing;
- as collapsible fluid reservoir formed from flexible material and disposed within the rigid housing, a dispense mechanism fluidly connected to the fluid reservoir and an outlet port fluidly connected to the dispense mechanism;
- a length of tubing fixedly connected to the outlet port of the infusion cartridge, the length of tubing in fluid communication with the outlet port of the infusion cartridge;
- and
- a connector operably connected to the length of tubing at a terminus of the tubing, the tubing extending as a unitary construct from the outlet port of the infusion cartridge to the connector, the connector adapted to connect to a cannula and/or needle to permit a fluid drug to flow from the infusion cartridge, through the length of tubing, and into the cannula and/or needle.
An infusion kit comprising;
- cannula comprising a first end configured to pierce a patient's skin and a second end;
- an infusion cartridge comprising:
- a rigid housing;
- a collapsible fluid reservoir formed from a flexible material and disposed within the rigid housing;
- a dispense mechanism fluidly connected to the fluid reservoir;
- an outlet port fluidly connected to the dispense mechanism;
- and
- an infusion set comprising:
- a length of tubing fixedly connected to the outlet port of the infusion cartridge, the length of tubing in fluid communication with the outlet port of the infusion cartridge;
- and
- a connector operably connected to the length of tubing at a terminus of the tubing, the tubing extending as a unitary construct from the outlet port of the infusion cartridge to the connector, the connector adapted to connect to the cannula to permit a fluid drug to flow from the infusion cartridge, through the length of tubing, and into the cannula via the second end of the cannula.
