Abstract: A case for an communication device is provided that includes a case body adapted to be secured to communication device having at least one video output oriented in a first direction and at least one audio output oriented in a second direction substantially perpendicular to the first direction, and a sound deflector secured to the case body, the sound deflector being moveable between an extended position and a retracted position, wherein the sound deflector is configured to direct audible sound emitted from the device substantially from the second direction to the first direction when in the extended position, and wherein the sound deflector is configured to conform to a portion of the case body when in the retracted position.

Abstract: A valve (10) comprises a housing (12) with a valve element (14) which normally fluidicly couples a low pressure operating device, such as a transducer (30) and tubing (34) to be coupled to a patient (36) along a first flow path (42) including a flexible control wall (58) which normally interrupts a second flow path (72) between a high pressure generating source such as an injector syringe (32) and the tubing (34), but which flexes, in response to high pressure excursions from the syringe (32) to allow the second flow path (72) to open as it flexes into the first flow path (42) to thereby restrict same thus providing protection to the transducer (30) during the high pressure excursion from the syringe (32).

Abstract: A modular interconnecting component support unit has a rigid plate (14) with a planar face (16) and a rib (24) and a slot (38) extending parallel the plate face but from opposite sides or edges (22, 34) of the plate so that two such units may be slid together while their faces are in planar relationship. Locking arms (46) adjacent the ends (40) of the slots (38) are provided to releasably grip a rib (24) of one unit received in the slot (38) of a second unit. A medical device, such as a reusable portion of a medical pressure transducer (20), may be permanently affixed to the plate face (16).
