Abstract
A user-wearable patch pump system for delivery of insulin or other medicament can include a patch pump having a reusable drive unit and a replaceable and refillable cartridge. The cartridge can selectively attach to and be detached from the drive unit. The cartridge can initially be inserted onto the drive unit in a first orientation at an angle to the drive unit and then be rotated to align the cartridge with the drive unit and lock the cartridge in place on the drive unit to form the patch pump.
Claims17
A user-wearable infusion pump system, comprising:
- a user-wearable infusion pump including a bolus input and no display;
- a retention frame having a perimeter shape generally matching a perimeter shape of the user-wearable infusion pump configured to releasably lock the user-wearable infusion pump thereon;
- an adhesive patch attached to the retention frame to adhere the retention frame to a body of a user;
- a remote control device configured to establish a connection with the user-wearable infusion pump;
- and
- infusion tubing extending from the user-wearable infusion pump with a connector at a distal end of the infusion tubing, wherein the connector is configured to attach to an end connector of an infusion set having tubing extending from the end connector to an infusion site connector configured to facilitate delivery of medicament from the user-wearable infusion pump to an infusion site remote from the user-wearable infusion pump, wherein the connector is in fluid communication with a medicament reservoir of the user-wearable infusion pump to facilitate refilling the reservoir with medicament,
- wherein the user-wearable infusion pump comprises a drive unit and a medicament cartridge including the reservoir selectively attachable to the drive unit, and
- wherein the medicament cartridge is configured to be inserted onto the drive unit in a first orientation with a front surface and a rear surface of the medicament cartridge in a non-parallel orientation with a front surface and a rear surface of the drive unit and to be rotated less than 360 degrees to selectively lock the medicament cartridge onto the drive unit with the front surface and the rear surface of the medicament cartridge being in a generally parallel orientation with the front surface and the rear surface of the drive unit.

A user-wearable infusion pump system, comprising:
- a user-wearable infusion pump including a bolus input and no display, the user-wearable infusion pump having a length of tubing with a connector extending therefrom, wherein the connector is in fluid communication with a medicament reservoir of the user-wearable infusion pump to facilitate refilling the reservoir with medicament;
- a retention frame having a perimeter shape generally matching a perimeter shape of the user-wearable infusion pump configured to releasably lock the user-wearable infusion pump thereon;
- an adhesive patch attached to the retention frame to adhere the retention frame to a body of a user;
- and
- a remote control device configured to establish a connection with the user-wearable infusion pump;
- and
- an infusion set including an end connector configured to attach to the connector of the user-wearable infusion pump and infusion tubing extending from the end connector to an infusion site connector, wherein the infusion set is configured to facilitate delivery of medicament from the user-wearable infusion pump to an infusion site coupled with the infusion site connector remote from the user-wearable infusion pump,
- wherein the user-wearable infusion pump comprises a drive unit and a medicament cartridge including the reservoir selectively attachable to the drive unit, and
- wherein the medicament cartridge is configured to be inserted onto the drive unit in a first orientation with a front surface and a rear surface of the medicament cartridge in a non-parallel orientation with a front surface and a rear surface of the drive unit and to be rotated less than 360 degrees to selectively lock the medicament cartridge onto the drive unit with the front surface and the rear surface of the medicament cartridge being in a generally parallel orientation with the front surface and the rear surface of the drive unit.
