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 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.
