Abstract
A pressure measuring device includes a housing which retains a pressure responsive element interconnected to an indicating member that moves relative to a dial face when a change of pressure is detected. A peripheral bumper is mounted to the housing exterior, the bumper including an extending portion which creates a discontinuous path for shock or impact loads applied to the bumper relative to a continual movement mechanism. The housing can further include a discontinuous region imposed in an engagement portion of the housing, the engagement portion permitting the housing to be directly attached to an inflatable blood pressure sleeve.
Claims10
A pressure measuring device, said device comprising:
- a housing;

- a movement mechanism having an input end in proximity to a moveable surface of said at least one pressure responsive element;
- an indicator connected to an output end of said movement mechanism which indicates changes in pressure;
- and shock absorbing means associated with the exterior of said housing for creating a noncontinuous path for preventing impinging shock and input loads from reaching the components disposed within said housing.
