Abstract
A fill adapter for filling a reservoir and a related method are disclosed herein.

Claims17
A method for filling an infusion pump having a reusable housing assembly having a pump, a disposable housing assembly with a reservoir and a septum fluidly connected to the reservoir for filling, a septum access assembly having a first position covering the septum and a second position providing access to the septum, a bias mechanism for biasing the septum access assembly to the first position, and a filling assembly having a needle, and a fluid, the method comprising:
- piercing the septum with the needle;
- inserting fluid to the reservoir through the needle;
- contacting the filling assembly to the septum access assembly;
- removing the needle from the septum, whereby the removal allows the bias mechanism to move the septum access assembly from the second position to the first position;
- and
- attaching the reusable housing assembly to the disposable assembly.
A method for filling a wearable infusion pump having a reusable housing assembly having a pump and fluid control mechanism, a disposable housing assembly having a reservoir and a septum fluidly connected to the reservoir for filling, a septum access assembly having a first position covering the septum and a second position proving access to the septum, a bias mechanism for biasing the septum access assembly to the first position, a fluid passage for passing the fluid to a patient and a filling assembly having a needle and a fluid, the method comprising:
- piercing the septum with the needle;
- inserting fluid to the reservoir through the needle;
- contacting the filling assembly to the septum access assembly;
- removing the needle from the septum, whereby the removal allows the bias mechanism to move the septum access assembly from the second position to the first position;
- and
- attaching the reusable housing assembly to the disposable assembly.
