  • Patent number: 10517486
    Abstract: A temperature probe includes a handle and a shaft extending from the handle. The shaft includes a distal end, a proximal end, and a tip at the distal end. The temperature probe also includes a capacitance sensor disposed on one of the handle and the shaft, the capacitance sensor configured to measure a change in capacitance when positioned proximate a conductor. The temperature probe further includes a temperature sensor disposed on the shaft, the temperature sensor configured to measure a body cavity temperature of a patient.

  • Patent number: 9220422
    Abstract: 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.

  • Publication number: 20080051637
    Abstract: 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.

  • Publication number: 20060252996
    Abstract: 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.

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.

  • Publication number: 20050027168
    Abstract: 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.
