Patent number: 11821356Abstract: A reed valve includes a first valve body portion that includes one or more inlet apertures fluidly coupled to a tapered second valve body portion that includes one or more outlet apertures. The reed valve includes at least one sealing surface disposed proximate the one or more outlet apertures and at least one petal continuously, reversibly, displaceable between an OPEN position permitting forward flow through the reed valve when a fluid pressure proximate the at least one inlet aperture exceeds a fluid pressure proximate the at least one outlet aperture and a CLOSED position preventing reverse flow through the reed valve when a fluid pressure proximate the at least one outlet aperture exceeds a fluid pressure proximate the at least one inlet aperture. The reed valve may be installed in an airbox assembly used with a turbocharged engine to reduce the occurrence of turbo-lag on acceleration.Type: GrantFiled: September 23, 2022Date of Patent: November 21, 2023Assignee: Moto Tassinari, Inc.Inventors: Steven M. Tassinari, Michael Ewaschuk

Publication number: 20230235827Abstract: A reed valve assembly includes a retainer, one or more reed cages, and a plurality of reed petals. The retainer includes a flange, first and second openings, and a center retainer separating the first and second openings. The reed cages are configured to be advanced from the bottom of the retainer and partially through the first and second openings of the retainer and have at least two inner openings generally facing each other and at least two outer openings generally facing away from each other. The inner and outer openings are configured to be fluidly coupled to the first and second openings of the retainer. The reed petals are configured to extend over the inner openings and the outer openings. The center retainer and reed cages include one or more reed cage grooves and reed cage flanges configured secure the reed cages to the retainer.Type: ApplicationFiled: January 26, 2023Publication date: July 27, 2023Inventors: Steven M.

Patent number: 8603037Abstract: A needle, catheter, and housing assembly is provided. The assembly includes a slider portion that slides relative to the housing. The slider portion can be actuated by a caregiver/operator such that a catheter can be threaded into a patient with simple movement of the operator's thumb or other finger. The assembly also includes an improved flash chamber. The flash chamber utilizes capillary action and/or a visible portal area to provide a caregiver/operator with more immediate information as to whether the needle has been inserted in the vein or artery.Type: GrantFiled: April 9, 2012Date of Patent: December 10, 2013Assignee: Dartmouth-Hitchcock ClinicInventors: Christopher W. Wiley, Michael Ewaschuk

Patent number: 7862553Abstract: A medical device includes a tube end to which a tip having a medical tool is attached. The tip includes a tip housing and a lock tab, as well as a yoke. The tube end includes an outer tube and an inner shaft, in which the inner shaft engages the yoke and the outer tube engages the tip housing. The lock tab fits into a recess in the outer tube to prevent twisting of the tip when engaged with the tube end, and the yoke includes a locking ring to which a spring protrudes, to fixedly and detachably connect the tip to the tube end.Type: GrantFiled: July 13, 2005Date of Patent: January 4, 2011Assignee: Microline Surgical, Inc.Inventor: Michael Ewaschuk
