  • Publication number: 20170043083
    Abstract: A system for delivery of a medical fluid to a patient includes a pump system including a pressurizing unit to pressurize the medical fluid and a drive system in operative connection with the pressurizing unit. The pump system exhibits variation in pressure during operation. The system further includes a compensating system in fluid connection with the medical fluid pressurized by the pressurizing unit. The compensating system defines a displacement volume in fluid connection with the pressurized medical fluid that is altered in a predetermined manner to alter the variation in pressure. The compensating system can, for example, reduce pulsatility of pressure during flow.

  • Patent number: 5667230
    Abstract: A rack lift assembly (10) includes a side mount plate (12) that can be connected to an equipment rack holding telecommunication equipment. A caster plate (14) connects to the side mount plate (12) by a loose pin hinge (26) and by a latch pin (18). The latch pin (18) has two apertures (22 and 24) that can receive a deadbolt (20) from caster plate (14). Caster plate (14) includes a wheel (34) that is placed in contact with the floor or ground when the deadbolt (20) is secured within the first aperture (22) of the latch pin (18), placing the caster plate (14) in its operating position. The caster plate (14) is placed in an inoperational position by securing the deadbolt (20) into the second aperture (24) of the latch pin (18). The side mount plate (12) includes rollers (16) that allow for transportation of telecommunication equipment during low clearance situations while the caster plate (14) is placed in its inoperational position.
