Abstract: This disclosure includes an apparatus for detecting mating of a cap with a fluid delivery device having a housing, a receptacle, and a sensor. The housing is configured to carry an insulin delivery device having a reservoir of the fluid. The receptacle is provided by the housing having a coupling with a locking recess configured to receive a cap with a sprung locking arm. The pressure sensor is carried by the receptacle proximate the coupling and configured to detect engagement force of the sprung locking arm with the receptacle when mated with the housing. A method is also provided.

Abstract: A flexible tubing for a cannula has a hollow tubing body having a length dimension from a first end to a second end, and an outer diameter of no more than 0.9 mm. The tubing body has a section of enhanced flexibility of a greater flexibility than one or more other sections of the tubing body. The section of enhanced flexibility is spaced from the first end of the tubing body by a distance D, where D is within a range of 3.0 mm to 5.0 mm for a flexible tubing having a length of about 9.0 mm, and where D is within a range of 1.0 mm to 2.9 mm for a flexible tubing having a length of about 6.0 mm.

Abstract: A device for delivering fluid to a user includes a fluid reservoir for holding the fluid, the fluid reservoir defining an internal volume and a stopper positioned in the internal volume of the fluid reservoir, wherein the stopper is formed with a cavity. The device further includes a piston having a distal end received within the cavity of the stopper and an actuator coupled to the piston for driving the piston into the internal volume of the fluid reservoir. Also, the device includes a coupling device for engaging the piston in the cavity of the stopper at a desired position and a sensor for determining whether the piston is engaged in the cavity of the stopper at the desired position.
