Battery shock absorber for a portable medical device
First Claim
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 perimeter sized and shaped to accommodate placement in the battery receptacle;
a through hole formed in the resilient material, the through hole being sized and shaped to accommodate the electrical contact;
a first side;
a second side; and
shock absorbing features formed on the first side or the second side to dissipate kinetic energy associated with motion of the battery relative to the battery receptacle, wherein the shock absorbing features comprise;
a plurality of angled outer depressions, each having a respective high edge near the through hole and having a respective low edge near the perimeter; and
a plurality of angled inner depressions, each having a respective high edge near the perimeter and having a respective low edge near the through hole.

Abstract
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.
