Patent number: 12133973Abstract: A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body, the plunger member. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is at least partially retractable into plunger interior. The needle proximal end feature includes an annular distally facing surface.Type: GrantFiled: March 29, 2021Date of Patent: November 5, 2024Assignee: Credence MedSystems, Inc.Inventors: Alan E. Shluzas, Stephen H. Diaz, John F. Shanley, Scott Segelke, John Merhige

Patent number: 5843691Abstract: A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for the color-change reaction. The inhibitor concentration increases in successive assay areas; thus, the number of areas that change color is a measure of the analyte concentration. The test strip is particularly adapted for measuring glucose in a whole blood sample. In a preferred embodiment, the sample is guided to the assay areas along a path formed by crushing selected areas of a membrane, and the assay areas are uncrushed areas of the membrane.Type: GrantFiled: December 31, 1996Date of Patent: December 1, 1998Assignee: Lifescan, Inc.Inventors: Joel Douglas, Ernest Kiser, Michael F.

Patent number: 5688307Abstract: A process for separating hydrocarbon gases of low boiling point, particularly methane, ethane and ethylene, from nitrogen. The process is performed using a membrane made from a super-glassy material. The gases to be separated are mixed with a condensable gas, such as a C.sub.3+ hydrocarbon. In the presence of the condensable gas, improved selectivity for the low-boiling-point hydrocarbon gas over nitrogen is achieved.Type: GrantFiled: February 29, 1996Date of Patent: November 18, 1997Assignee: Membrane Technology and Research, Inc.Inventors: Ingo Pinnau, Kaaeid Lokhandwala, Phuong Nguyen, Scott Segelke

Patent number: 5669958Abstract: A membrane separation process for treating a gas stream containing methane and nitrogen, for example, natural gas. The separation process works by preferentially permeating methane and rejecting nitrogen. We have found that the process is able to meet natural gas pipeline specifications for nitrogen, with acceptably small methane loss, so long as the membrane can exhibit a methane/nitrogen selectivity of about 4, 5 or more. This selectivity can be achieved with some rubbery and super-glassy membranes at low temperatures. The process can also be used for separating ethylene from nitrogen.Type: GrantFiled: February 29, 1996Date of Patent: September 23, 1997Assignee: Membrane Technology and Research, Inc.Inventors: Richard W. Baker, Kaaeid A. Lokhandwala, Ingo Pinnau, Scott Segelke

Patent number: 5611841Abstract: A gas-separation method for controlling vapor emissions. The method employs a spiral-wound membrane module, adapted to provide one or more feed-side baffles in the feed channel. The method may be used to control vapor emissions from a volatile liquid, and is particularly useful to control fuel vapors emitted during fuel transfer operations.Type: GrantFiled: September 29, 1995Date of Patent: March 18, 1997Assignee: Membrane Technology and Research, Inc.Inventors: Richard W. Baker, Douglas Gottschlich, Thomas Hofmann, Scott Segelke, Matthias Wessling
