Patent number: 9220422Abstract: A blood pressure sleeve includes a first sheet having a top side and a bottom side and a second sheet having a top surface and a bottom surface. The second sheet is attached to the first sheet and defines an inflatable portion, the first and second sheets each having a fluid impermeable surface. The inflatable portion includes an opening sized for receiving a port that interconnects the exterior of the sleeve with the interior of the inflatable portion and in which the first sheet includes a slotted portion opposite the port and aligned therewith to receive the port when the sleeve is wrapped about the limb of a patient, and in which at least a portion of the wrapped cuff is treated to reduce frictional effects.Type: GrantFiled: November 19, 2012Date of Patent: December 29, 2015Assignee: WELCH ALLYN, INC.Inventors: Raymond A. Lia, Robert L. Vivenzio, Eric Andreassen, Daniel Sivilich, Jeffrey J. Perkins, Michael T. McMahon, Chris R. Roberts, Richard A. Tamburrino

Publication number: 20080051637Abstract: A digital otoscope for capturing live and still digital images of body tissue and having associated optical characteristics that improve the quality of visual information gathered for medical inspection of both human and veterinary subjects. The digital otoscope includes a tip element having dimensions that are small enough to fit into a small body cavity, such as an ear canal. The tip element and the otoscope enclose an assembly of optical components yielding optical characteristics that provide a substantially wide field of view and a substantially wide range of optimal focus from which to form visual information within a small and confined body cavity.Type: ApplicationFiled: August 27, 2007Publication date: February 28, 2008Applicant: Welch Allyn, Inc.Inventors: Eric Andreassen, David Fallat, Ervin Goldfain, John Strom, John Delaney, Howard Haines, Corinn Fahrenkrug, Cynthia Kuiper

Publication number: 20060252996Abstract: A veterinary otoscope permitting examination of an ear is defined by an instrument head including a proximal end and a distal insertion portion that is insertable into the ear. The veterinary otoscope includes an imaging lens train disposed within the instrument head, wherein each of the imagine lens train, an eyepiece and a distal opening of said insertion portion are aligned along an optical axis. The veterinary otoscope further includes a focusing mechanism for selectively moving at least one of the imagine lens train and the optics contained within the eyepiece relative to one another along the optical axis. The imagine lens train and the optics in the eyepiece define an optical system such that an entrance pipil is substantially located in the distal insertion portion of the instrument head, thereby enabling the entire tympanic membrane to be viewed at once by the user.Type: ApplicationFiled: March 28, 2006Publication date: November 9, 2006Inventors: Ervin Goldfain, Steven Slawson, Eric Andreassen, Kimberly McNeilly, Elizabeth Staples

The otoscope includes an imaging lens train disposed within the instrument head, wherein each of the imaging lens train, an eyepiece and a distal opening of said insertion portion are aligned along an optical axis. The otoscope further includes a focusing mechanism for selectively moving at least one of the imaging lens train and the optics contained within the eyepiece relative to one another along the optical axis. The imaging lens train and the optics in the eyepiece define an optical system such that an entrance pupil is substantially located in the distal insertion portion of the instrument head, thereby enabling the entire tympanic membrane to be viewed at once by the user.Type: ApplicationFiled: July 23, 2004Publication date: February 3, 2005Applicant: Welch Allyn, Inc.Inventors: Ervin Goldfain, Steven Slawson, Eric Andreassen, Cynthia Kuiper, Elizabeth Staples, Raymond Lia

Publication number: 20050027168Abstract: A tip element for an otoscopic apparatus includes engagement features that permit selective attachment to two different tip attachment mechanisms. The tip element includes both interior and exterior engagement features that provide interchangeability with otoscopes having different tip attachment schemes. The tip element includes an increased distal aperture formed from a decreased slope that enables a larger field of view, permitting the entire tympanic membrane to be viewed at once. External engagement features permit ejection of the tip from the otoscope, as well as stackability of a plurality of tip elements.Type: ApplicationFiled: July 23, 2004Publication date: February 3, 2005Applicant: Welch Allyn, Inc.Inventors: John Strom, Cynthia Kuiper, Chris Roberts, Michael Bausch, Allan Krauter, Eric Andreassen, David Woods
