Fluid reservoir and systems for filling a fluid reservoir of a fluid infusion device
First Claim
1. A system for filling a fluid reservoir of a fluid infusion device with a fluid, the system comprising:
- the fluid reservoir having a first portion and a second portion, with a fluid chamber defined between the first portion and the second portion, the second portion movable within the first portion and including an interface, the second portion including a stopper and the interface is coupled to the stopper, the interface including a pair of locking projections that are opposite each other about a perimeter of the interface; and
a transfer guard including a first end and a second end, the first end to be coupled to a source of the fluid and the second end having a pair of locking members opposite each other about a perimeter of the second end, each of the pair of locking members to couple to a respective one of the pair of locking projections of the interface, each of the pair of locking projections having a locking arm that is spaced apart from the second end by a stem, and the locking arm is arcuate to at least partially follow the perimeter of the second end, the transfer guard defines a fluid flow path for the fluid from the source, and the transfer guard is movable relative to the first portion to fill the fluid chamber with the fluid.

Abstract
A system for filling a fluid reservoir of a fluid infusion device with a fluid is provided. The system includes the fluid reservoir having a first portion and a second portion. A fluid chamber is defined between the first portion and the second portion. The second portion is movable within the first portion and includes an interface. The system includes a transfer guard having a first end and a second end. The first end to be coupled to a source of the fluid and the second end having at least one locking member that couples to the interface. The transfer guard defines a fluid flow path for the fluid from the source, and the transfer guard is movable relative to the first portion to fill the fluid chamber with the fluid.

8. A system for filling a fluid reservoir of a fluid infusion device with a fluid, the system comprising:
-
the fluid reservoir having a barrel portion and a plunger portion, with a fluid chamber defined between the barrel portion and the plunger portion, the plunger portion movable within the barrel portion and including an interface having a pair of locking projections that are opposite each other about a circumference of the interface; and a transfer guard including a first end and a second end, the first end to be coupled to a source of the fluid, the second end including a pair of locking members opposite each other about a circumference of the second end, each of the pair of locking members to couple to a respective one of the locking projections of the interface to couple the transfer guard to the fluid reservoir, each of the pair of locking projections having a locking arm that is spaced apart from the second end by a stem, the locking arm is arcuate to at least partially follow the circumference of the second end, and the second end includes at least one piercing member that defines a fluid flow path from the source of the fluid to the fluid chamber, and the transfer guard is movable relative to the barrel portion to fill the fluid chamber with the fluid. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
