Abstract: A mount for supporting a cylindrical bottle includes an annular core having an inner side surface defining a hollow opening, an outer side surface, a top surface and a base surface. A plurality of pliable ribs each at least partially encircles the annular core so as to overlap the outer side surface, the top surface and the base surface such that at least an upper end of each rib where it overlaps the top surface extends into the hollow opening. The mount may be used in conjunction with a collar having a body portion for surrounding the bottleneck and defining along at least a portion of an axis thereof a substantially quadrilateral cross-section having in each corner thereof a respective arcuate recess.

Abstract: A passing tray for surgical instruments includes a holder having a base portion, opposing side portions open at a first end and an end portion. A sliding member having front and rear edges is slidably supported within the holder. At least one support member projects upwardly from a surface of the sliding member toward its front edge, and an actuator projects upwardly from the surface of the sliding member intermediate the front and rear edges thereof and has front and rear surfaces facing toward the front and rear edges of the sliding member, respectively. In use an elongated surgical instrument may be retained transversely between opposing surfaces of the support member and the open first end of the holder under force of the actuator.
