APPARATUS, SYSTEM AND METHOD FOR FLUID DELIVERY
A filling aid. The filling aid includes a locking portion including a groove feature; and a locking feature having a locked and an unlocked position; and a filling syringe holder slidably attached to the locking portion, the filling syringe holder including a filling needle cradle portion having a tongue feature; and a needle housing portion comprising at least one tab having a starting position and a filling position, wherein the groove feature configured to accommodate the tongue feature, and wherein the locking feature interact with the filling syringe holder wherein when the locking feature moves from the locked position to the unlocked position the needle housing portion moves from the starting position to the filling position.
1 . 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.
2 . The method of claim 1 further comprising:
before piercing the septum, contacting the filling assembly to the septum contact assembly to move the septum access assembly from the first position to the second position.
3 . The method of claim 2 wherein the septum access assembly has an opening and the method further comprising:
The filling assembly entering the opening to move the access assembly from the first position to the second position.
4 . The method of claim 1 where in the septum access assembly has a latched and unlatched position and the septum access assembly is latched in the second position, and the step of piercing the septum with the needle further comprised unlatching the septum access assembly.
5 . The method of claim 1 wherein the septum access assembly has a sliding shutter and the step of moving from the second position to the first position further comprises sliding the shutter.
6 . The method of claim 2 wherein the septum access assembly has a sliding shutter and the step of moving from the second position to the first position further comprises sliding the shutter.
7 . The method of claim 4 wherein the septum access assembly has a sliding shutter and the step of moving from the second position to the first position further comprises sliding the shutter.
8 . The method of claim 1 wherein the septum access assembly has a shutter that pivots between the first position and the second position and the step of moving from the second position to the first position further comprises pivoting the shutter.
9 . The method of claim 4 wherein the septum access assembly has a shutter that pivots between the first position and the second position and the step of moving from the second position to the first position further comprises pivoting the shutter.
10 . The method of claim 1 further comprising:
Priming the disposable assembly.
11 . The method of claim 1 wherein the step of attaching the reusable housing assembly to the disposable assembly further comprises rotating the reusable housing assembly relative to the disposable assembly.
12 . 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.
13 . The method of claim 12 wherein the reusable housing assembly has a sensor for sensing the attachment of the reusable housing assembly, the method further comprising:
sensing the attachment of the reusable housing assembly to the disposable assembly.
14 . The method of claim 12 wherein the reusable housing assembly has a rechargeable battery, the method further comprising:
charging the reusable housing assembly prior to attaching the reusable housing assembly to the disposable assembly.
15 . The method of claim 12 further wherein the reusable housing assembly has a volume sensor, the method further comprising;
after attaching the reusable housing assembly to the disposable assembly, sensing the volume of the reservoir.
16 . The method of claim 12 further comprising:
Priming the disposable assembly.
17 . The method of claim 16 further comprising:
Priming the disposable assembly.
