Systems, apparatuses and methods for fluid infusion into a body
First Claim
1. A portable fluid infusion device, comprising:
- a first reservoir;
a second reservoir including a plunger and a hollow needle, the hollow needle configured to allow flow of fluid into and/or out of the second reservoir;
a dual chamber assembly comprising a first chamber compartment and a second chamber compartment;
an exit port;
a first conduit configured to communicate fluid between the first reservoir and the first chamber compartment of the dual chamber assembly; and
a second conduit configured to communicate fluid between the exit port and the second chamber compartment of the dual chamber assembly;
wherein;
a tip or an opening of the hollow needle is configured to transition from the second chamber compartment to the first chamber compartment upon displacement of the second reservoir in a first direction and from the first chamber compartment to the second chamber compartment upon displacement of the second reservoir in a direction opposite to the first direction,the first reservoir includes a plunger configured to transition between a distal end and a proximal end of the first reservoir in the first direction and/or in the direction opposite to the first direction, andan advancement of the second plunger in the direction opposite to the first direction causes fluid flow from the first reservoir to the second reservoir.

Abstract
Embodiments of the current disclosure are directed toward systems, devices and methods for diabetes management. In particular, the present disclosure relates to devices and methods for dispensing insulin to a patient. A portable fluid infusion device, comprising a disposable part (DP) and a reusable part (RP) is disclosed. The DP comprises a first reservoir and a second reservoir, the second reservoir less than or equal to the first reservoir in length, while the RP comprises a first compartment configured to receive the first reservoir, a second compartment configured to receive the second reservoir and a gasket for sealing a junction between the second reservoir and the second compartment upon connection of the RP and the DP.
