    Abstract: A sample testing cartridge is usable to perform a variety of tests on a visco-elastic sample, such hemostasis testing on a whole blood or blood component sample. The cartridge includes a sample processing portion that is in fluid communication with a sample retention structure. A suspension, such as a beam, arm, cantilever or similar structure supports or suspends the sample retention portion relative to the sample processing portion in a unitary structure. In this manner, the sample retention portion may be placed into dynamic excitation responsive to excitation of the cartridge and correspondingly dynamic, resonant excitation of the sample contained within the sample retention portion, while the sample processing portion remains fixed. Observation of the excited sample yields data indicative of hemostasis. The data may correspond to hemostasis parameters such as time to initial clot formation, rate of clot formation, maximum clot strength and degree of clot lysis.

  • Publication number: 20190283044
    Abstract: A method and apparatus for separating cell suspension into centrate and concentrate includes a solid wall rotatable centrifuge bowl (82). A single use rotatable core (88) is positioned in the bowl and bounds a cavity (90) which serves as a separation chamber. The bowl rotates about an axis (84). An inlet tube (92) and an outlet tube (102) extend along the axis in the bowl cavity. The centripetal pump (98) in the cavity is in connection with the outlet tube. The centrate discharge pump (120) is in connection with the outlet tube. A pressure damping reservoir (122) is fluidly connected between the outlet tube and the discharge pump. At least one control circuit (142) is operative to control the apparatus to maintain a positive pressure above atmospheric pressure within the cavity, so as to maintain the cell suspension away from at least one seal (106) that bounds the interior of the cavity.

    Abstract: An apparatus for separating cell suspension material into centrate and concentrate, includes a single use structure (178, 240, 250) releasably positioned in a cavity in a solid wall rotatable centrifuge bowl (172). The bowl and portions of single use structure rotate about an axis (174). A stationary inlet feed tube (184), a centrate discharge tube (212) and a concentrate discharge tube (230) extend along the axis of the rotating single use structure. A centrate centripetal pump (208) is in fluid connection with the centrate discharge tube. A concentrate centripetal pump (216) is in fluid connection with the concentrate discharge tube. A controller (274) operates responsive to sensors (264, 270) in respective centrate and concentrate discharge lines (262, 268), to control flow rates of a concentrate pump (272) and a centrate pump (266) to produce output flows of cell concentrate and generally cell free centrate.

  • Publication number: 20190283047
    Abstract: An arrangement for spraying a fluid to a piece of material, such as a web or strip, has a chamber through which the material runs, and an applicator (15) which is configured to spray the fluid on the material. The applicator includes at least a first and a second valve (16, 16a, 16b, 16c) arranged within the chamber, each valve having a longitudinal axis, and each valve comprising a spray nozzle (17, 17a, 17b, 17c). Each spray nozzle has an elongated opening extending along an axis. The longitudinal axis of the valve and the axis of the corresponding nozzle span a plane and the at least said first valve and said second valve are arranged spaced on a common axis (CA) running through a center point of each valve. The plane is inclined in relation to the common axis.

    Abstract: A multi-mode fluid nozzle includes a generally-cylindrical mixing chamber with a stream mode fluid inlet connected to one side of the chamber, a fluid outlet connected to the opposite side of the chamber and a plurality of mist mode fluid inlets connected to the periphery of the chamber. The discharge pattern of the multi-mode fluid nozzle is dependent upon the inlets from which fluid enters the mixing chamber such that when the fluid enters the mixing chamber through the stream mode fluid inlet, the fluid exits the fluid outlet in a stream flow discharge pattern, when the fluid enters the mixing chamber through the mist mode fluid inlets, the fluid exits the fluid outlet in a mist flow discharge pattern and when the fluid enters the mixing chamber through the stream mode and the mist mode fluid inlets, the fluid exits the fluid outlet in a droplet flow discharge pattern.

  • Publication number: 20190283052
    Abstract: An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.
