  • Sensor mounting pad and method
    Patent number: 5644093
    Abstract: A mounting pad for mounting a sensor transducer, such as an ultrasonic level sensor, on a fluid reservoir, such as a blood reservoir. The mounting pad comprises a bayonet-type locking mechanism for mounting the transducer on the mounting pad, and a pair of foot pads connected to the body of the mounting pad by living hinges. The living hinges are provided along an outer surface of the foot pads at a location intermediate the edges of the foot pads, such that the foot pads can pivot relative to the body to conform to the configuration of the reservoir and such that any forces applied to the foot pads via the body of the mounting pad are applied intermediate the edges of the foot pads, as opposed to directly along the edges.
