Slip ring spacer and method for its use
First Claim
1. An apparatus for use with a medical ultrasound system, the medical ultrasound system including an ultrasonic transducer, the apparatus comprisinga first electrical connector;
- a second electrical connector;
a slip ring including a first electrical connection ring and a second electrical connection ring concentrically arranged with the first electrical connection ring, at least one of the first and second electrical connection rings coupled with the transducer; and
a slip ring spacer configured for use with the slip ring, the slip ring spacer comprising a base formed from a non-conductive and fluid resistant material, a first aperture extending through the base, a second aperture extending through the base, a first flange projecting from the base, and a second flange projecting from the base, the first aperture being configured to receive and support the first electrical connector so that a portion of the first electrical connector projects above the first and second flanges to contact the first electrical connection ring, the second aperture being configured to receive and support the second electrical connector so that a portion of the second electrical connector projects above the first and second flanges to contact the second electrical connection ring, the first and second flanges having a concentric arrangement to define a first circular surface region on the base so that the first electrical connection ring of the slip ring is aligned with the first circular surface region.

Abstract
An interchangeable transducer for use with an ultrasound medical system having a keyless adaptor and capable of operating in a wet environment. The interchangeable transducer has an adaptor for engaging a medical system, an ultrasound transducer and additional electronics to provide a self-contained insert for easy replacement and usage in a variety of medical applications. A slip ring spacer is also disclosed, the slip ring spacer for use with a pancake slip ring having a base and flange configuration to form one or more channels around each contact ring of the pancake slip ring. The channels provide fluid isolation around each connector to help reduce electronic cross talk and contact corrosion between the connector pads of the slip ring while the slip ring is immersed in a wet environment.
