  • Patent number: 11399709
    Abstract: An otoscopic tip element having an axisymmetric hollow body having a substantially conical shape and made from a moldable plastic material includes a distal opening, a proximal opening, an interior surface, and an exterior surface. To maximize light transmissivity, a distal portion of the interior surface is provided with a smooth or polished surface finish and a proximal portion of the interior surface and the outer surface is provided with a textured surface finish such that light from a light source of an otoscope can be axially directed through the hollow body for emission through the distal opening, as well circumferentially through the exterior surface. The surface finish and color/tint of the speculum tip element can be adjusted or tuned to promote axial, circumferential and total light output relative to an intended medical target.

  • Patent number: 11382558
    Abstract: An imaging device for monitoring a skin feature includes a camera, at least one processor and memory. The imaging device displays a body area guide, receives a selection of a body area, initiates an image sequence of the body area, the image sequence including capturing, using the camera, a plurality of images, determines whether all body areas have been imaged, analyzes the images, and provides the analyzed images to a clinician. The imaging device can be part of a system including a server in communication with a monitor, where the clinician views the images on the monitor. Additionally, each skin feature can be ranked in order of risk and presented to the clinician in that order.

  • Patent number: 11373737
    Abstract: A dynamic medical object information base (DMOIB) is used with a communication protocol. A medical object information base (MOIB) may generally define rules of creation and modification of data defined for use in medical products. A dynamic version of the MOIB adapts to changing data classifications. DMOIB is preferably compatible with non-dynamic MOIB systems. DMOIB preferably reduces code space and simplifies management of software projects. DMOIB may allow for an entirely dynamic system using a discovery/negotiation process for determining full features of a device. DMOIB may also allow for generation of a dynamic interface to handle data from devices.

  • Patent number: 11363950
    Abstract: Fundus imaging includes selective illumination and exposure of an image sensor array. Fundus imaging systems and methods disclosed herein are wide field of view imaging typically conducted under non-mydriatic conditions. At a first time, an illumination unit illuminates a first portion of an eye fundus. At a second time, the illumination unit illuminates a second portion of the eye fundus. One or more fundus images are captured during illumination.

  • Patent number: 11350834
    Abstract: A blood pressure cuff is defined by a first sheet, having an opening, and a second sheet. The second sheet is attached to a bottom of the first sheet to form an interior inflatable portion between the first sheet and the second sheet, with the opening of the first sheet fluidly interconnecting the interior inflatable portion with an exterior of the cuff. The blood pressure cuff is made from a single type of material and can be recycled, biodegradable, or composted.

  • Patent number: 11344254
    Abstract: An example system for estimating a hydration level of an individual can include: a mechanism configured to apply mechanical pressure to a digit of the individual; an light detector configured to sense the light from the digit; and a controller programmed to perform functions including: send a first signal to the mechanism to apply the mechanical pressure to the digit; send a second signal to the mechanism to release the mechanical pressure on the digit; determine a capillary refill time based upon a third signal from the light detector indicating an amount of time for capillaries of the individual to refill with blood; and estimate the hydration level of the individual based upon the capillary refill time and one or more additional parameters.

  • Patent number: 11331014
    Abstract: A physiological parameter sensor system includes a housing with a first cell and a plurality of second cells. A first sensor system element (either an emitter or a detector) resides in the first cell. Second sensor system elements reside in at least some of the second cells. If the first sensor system element is an emitter, each second sensor system element is a detector, and vice versa. The housing is conformable to the contours of a patient to ensure that the sensor system elements are closely coupled to the patient's skin. The system identifies the emitter which yields the best quality signal at the detector (or the detector which receives the best quality signal from the emitter). The system then uses only the identified emitter/detector pair. The system is compact, places only modest demands on battery power, and tolerates being positioned at a nonoptimal locations on the patient's body.

  • Patent number: 11251635
    Abstract: A vital signs monitor includes an equipment housing defining an equipment compartment, a circuit assembly and a battery residing inside the equipment compartment, an electrical connector forming a connection between the battery assembly and the circuit assembly, and a battery discharge circuit. A retainer joined to the equipment housing retains the battery assembly in the housing. The retainer is separable from the housing so that its separation causes a break in the electrical connection and activates the discharge circuit.
