Apparatus for Detecting Mating of a Cap with a Fluid Delivery Device and Method

A method of detecting user mating/demating of a cap and a delivery tube with a fluid delivery device, comprising:

• providing a housing supporting a reservoir of fluid having a receptacle, a cap with a fluid insulin delivery tube configured to removably mate with the receptacle, and a pair of mating interlocking connectors provided between the cap and the receptacle, the connectors on the cap having a locking wing with a outwardly extending finger extending from a flexible arm that is urged inwardly when de-mating and mating the cap from the receptacle proximate a locked position;
• detecting a force from the urged flexible arm while engaging and disengaging the cap from the receptacle;
• and
• recording in a memory the detected force between the cap and the receptacle during mating and demating.
