Medical device with membrane keypad sealing element, and related manufacturing method

摘要

A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, other internal components in the housing, and a keypad external to the housing. The device includes a number of features and elements that enhance its operation, manufacturability, reliability, and user-friendliness. These features and elements include a shock absorbing element for a battery of the device, a keypad actuator layer that overlies a keypad assembly and forms a water resistant seal with the housing, and an offset element for a piezoelectric speaker that is located inside the housing.

主权项

1. A medical device comprising:
a housing having a front face, a keypad mounting cavity on the front face, and a sealing rim on the front face, the sealing rim surrounding the keypad mounting cavity; a membrane keypad assembly coupled to the housing and positioned inside the keypad mounting cavity, the membrane keypad assembly comprising a plurality of actuation components integrated therein; a sealing element comprising a perimeter area, the sealing element overlying the membrane keypad assembly such that the perimeter area extends beyond the membrane keypad assembly, and the perimeter area coupled to the sealing rim to form a fluid resistant seal with the housing; and a graphic keypad overlay removably adhered to the sealing element to be replaceable with a different graphic keypad overlay, the graphic keypad overlay comprising graphical representations corresponding to the actuation components.
