1. A fluid infusion device, comprising:
- a fluid reservoir having a first portion and a second portion; and
a housing defining a receiving portion for removably receiving the fluid reservoir within the housing, the housing having a first side adjacent to a second side, the first side including a first engagement system that cooperates with the first portion and the second side including a second engagement system that cooperates with the second portion, the first engagement system including a wedge and a pin, the pin fixedly coupled to the first side of the housing and the wedge movable along the pin between a first position and a second position to bias the fluid reservoir relative to the housing in a direction substantially opposite a direction of fluid flow out of the fluid reservoir.

Abstract
A fluid infusion device is provided. The fluid infusion device can include a fluid reservoir having a barrel portion and a housing defining a receiving portion for removably receiving the fluid reservoir within the housing. The housing can have a first side including a first engagement system that cooperates with the barrel portion to bias the fluid reservoir relative to the housing in a direction substantially opposite a direction of fluid flow out of the fluid reservoir.

15. A fluid infusion device, comprising:
-
a fluid reservoir having a first portion, a second portion and a reservoir defined between the first portion and the second portion for receipt of insulin, the first portion having a first alignment feature; a first housing component having a first side, the first side including a first engagement system disposed entirely within the first housing component that cooperates with the first portion, the first engagement system including a wedge and a pin, the pin fixedly coupled to the first side of the housing and the wedge movable along the first side of the housing on the pin by the first alignment feature between a first position and a second position within the first housing component to bias the fluid reservoir relative to the first housing component in a direction substantially opposite a direction of fluid flow out of the fluid reservoir; and a second housing component coupled to the first housing component and including at least partially a second engagement system that cooperates with the second portion of the fluid reservoir, wherein in the second position, the wedge biases the fluid reservoir into contact with the second housing component. - View Dependent Claims (16, 17, 18, 19)
