Patent number: 9642777Abstract: Detection of fluid conditions in an administration set. A light source is positioned to transmit an infrared light through administration set tubing and any fluid therein. A light sensor senses the infrared light transmitted through the tubing and generates an output signal. A frequency of the output signal is a function of an intensity of the light transmitted through the tubing. A processor receives and determines the frequency of the output signal, and compares the determined frequency to threshold frequency values to determine whether fluid is in the tubing. The processor also monitors the generated output signal to determine if the frequency of the output signal changes over time, and determines whether fluid is flowing in the tubing as a function of the determined change in frequency.Type: GrantFiled: June 13, 2014Date of Patent: May 9, 2017Assignee: Covidien LPInventors: Thomas G. Lewis, William J. Byrd, Joseph A. Hudson

Patent number: 4158035Abstract: A pipetting device comprising a housing and a plurality of tubes mounted on the housing. The housing has a manifold chamber and a plurality of passages leading from the tubes, respectively, to the manifold chamber. A flexible impervious membrane extends across the passages to divide each of the passages into a first passage section and a second passage section. The first passage sections provide communication between the tubes and one side of the membrane, and the second passage sections provide communication from the other side of the membrane to the manifold chamber. A substantially incompressible flowable material, such as a liquid, fills the second passage sections and the manifold chamber. A mechanism is provided for moving the flowable material to deflect the membrane in opposite directions whereby liquid can be drawn into, and expelled from, the tubes.Type: GrantFiled: March 15, 1978Date of Patent: June 12, 1979Inventors: Thomas Haase, William J. Byrd

Patent number: 3986028Abstract: Apparatus is disclosed for measuring the level of gamma radiation contained in a plurality of biological samples which are located on the fibrous sheet member carried by a sample holder. The apparatus is adapted to count the radiation level of the number of closely spaced samples located in rows and columns on the sheet by automatically sequencing through the individual samples within the rows and to advance the holder to bring successive rows into proximity with the detector. The detector is moved from sample to sample within the rows, although a number of detectors can be employed. A plurality of sample holders are automatically advanced to the detector.Type: GrantFiled: January 20, 1975Date of Patent: October 12, 1976Assignee: The Salk Institute for Biological StudiesInventor: William J. Byrd

Patent number: 3982438Abstract: A Multiple Sample Pipetting Device is disclosed which is adapted to remove small predetermined volumes of liquid from a plurality of sample wells arranged in a compact rectilinear array, or conversely to transfer small predetermined volumes of liquid from one large reservoir container to a plurality of sample wells arranged in the same array. The apparatus has a plurality of small tubes extending downwardly with the upper end portion communicating with reservoirs that have a predetermined volume. A flexible diaphragm extends across all of the reservoirs, and the upper ends thereof are in communication with a common manifold chamber. The application of positive or negative pressure moves the diaphragm downwardly and upwardly into contact with the lower and upper reservoir walls, respectively, and either extracts or expels liquid from the tubes.Type: GrantFiled: June 23, 1975Date of Patent: September 28, 1976Assignee: The Salk Institute for Biological StudiesInventor: William J.
