Appl. No.:

11/760089

Smiths Medical ASD, Inc. - Rockland MA

International Classification:

A61B 19/00

US Classification:

604408, 604403

Abstract:

A flow-through fluid reservoir includes a body with a first fluid port, a member movable within the body by an actuator to increase or decrease a volume of a chamber defined by a sidewall of the body. The actuator has a second fluid port. Movable member has a fluid path therethrough such that fluid ports are in fluid communication irrespective of the position of the movable member or the volume of chamber. A shaped slot on the shell of the actuator and a projection on the body cooperate to constrain relative movement of the body and actuator along a path corresponding to the shaped slot. The slot advantageously may include a stop intermediate therealong. A canted aspect of the slot may be used to initiate relative movement of the member within body. The body includes an end wall through which the first fluid port communicates. A shroud is defined by a coaxial extension of the sidewall beyond the end wall to surround the first fluid port, and gripping elements may be provided on the shroud.

International Classification:

US Classification:

73708

Abstract:

A pressure transducer (10) for measuring fluid pressure in a fluid path comprising a strain gauge circuit (37) of thick film piezoresistors formed on an alumina diaphragm (36) in a Wheatstone bridge configuration. Each resistance leg of the bridge typically includes a thick film measuring piezoresistor (R1A) to which selected thick film patch-in piezoresistors (R1B, R1C, R1D, R1E) are selectively connected to create a measuring resistance network (PN1). The measuring resistance network is adjusted to a predetermined resistance value to balance and optimize the electrical symmetry of the bridge. The pressure transducer (10) includes a mechanical stop member (46) located adjacent the alumina diaphragm (36) such that the fully deflected diaphragm contacts the stop thereby physically preventing the diaphragm from deflecting an amount that would cause the diaphragm to rupture.

International Classification:

B63C 11/49

Abstract:

A water window apparatus including a main water window element, and a plurality of retaining flanges, along with interlocking teeth that fixedly communicate with one another to fixedly retain the main water window there between. The main water window is hollow, as well as monolithic and hermetically sealed to maintain its integral buoyancy, and further has a top that includes a magnifying element that imparts magnification when viewed therethrough.
