Battery shock absorber for a portable medical device

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 shock absorbing element for a battery of a medical device having a battery receptacle for the battery and having an electrical contact for the battery, the electrical contact residing within the battery receptacle, the shock absorbing element composed of a resilient material and comprising:
a circumference sized and shaped to accommodate placement in the battery receptacle; a through hole defined through the shock absorbing element to accommodate the electrical contact; a first side opposite a second side; a plurality of first shock absorbing features formed in an alternating pattern about the circumference on the first side; and a plurality of second shock absorbing features formed in an alternating pattern about the circumference on the second side, wherein the plurality of first shock absorbing features and the plurality of second shock absorbing features extend in a radial direction.
