15. A system for retaining a fluid delivery device, the fluid delivery device comprising a reservoir and a plunger arm operatively connectable to a plunger head that is moveable within the reservoir, the plunger arm having an arm portion that is configured for operative engagement to a drive member configured to move the arm portion and the plunger head when the arm portion of the plunger arm is operatively engaged to the drive, the system comprising:
-
a housing configured to support the plunger arm and the reservoir, the housing having a recess for receiving the plunger arm; the housing having a pair of protrusions arranged around the recess to allow the plunger arm to be forced between the protrusions and moved into the recess from a position outside of the recess when a first amount of force is applied on the plunger arm toward the recess, the protrusions being configured to prevent the plunger arm from being removed from the recess using the first amount of force when the plunger arm is in the recess, the protrusions further being configured to allow the plunger arm to be removed from the recess through the protrusions to a position outside of the recess when a second amount of force is applied on the plunger arm away from the recess, the second amount of force being greater than the first amount. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of manufacturing a system for retaining a fluid delivery device, the fluid delivery device comprising a reservoir and a plunger arm operatively connectable to a plunger head that is moveable within the reservoir, the plunger arm having an arm portion that is configured for operative engagement to a drive member configured to move the arm portion and the plunger head when the arm portion of the plunger arm is operatively engaged to the drive, the method comprising:
-
configuring a housing to support the plunger arm and the reservoir, the housing having a recess for receiving the plunger arm; and arranging in the housing a pair of protrusions around the recess to allow the plunger arm to be forced between the protrusions and moved into the recess from a position outside of the recess when a first amount of force is applied on the plunger arm toward the recess, the protrusions being configured to prevent the plunger arm from being removed from the recess using the first amount of force when the plunger arm is in the recess, the protrusions further being configured to allow the plunger arm to be removed from the recess through the protrusions to a position outside of the recess when a second amount of force is applied on the plunger arm away from the recess, the second amount of force being greater than the first amount.
