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).
