An intraoperative tissue oximetry device includes a tissue marker that includes one or more pens or one or more similar ink sources, such that the tissue marker can mark tissue according to oxygen saturation measurements made by the tissue oximetry device, thereby visually delineating regions of potentially viable tissue from regions of potentially nonviable tissue.

Tissue oximetry probe with tissue marking feature

A system includes an enclosure having a processor and a memory coupled to the processor. The enclosure includes a display coupled to the processor where the display is visible from an exterior of the enclosure; and a battery within the enclosure coupled to the processor and the display. The enclosure includes a probe tip coupled to an exterior of the enclosure. The probe tip includes first, second, and third sensor openings. A first distance between the first and second sensor openings is different than a second distance between the first and third sensor openings. The enclosure includes code stored in the memory where the code is executable by the processor, and includes code to receive first data associated with the first and second sensor openings, code to receive second data associated with the first and second sensor openings, and code to perform SRS using the first and the second data.

Wireless, handheld tissue oximetry device

A tissue oximetry device utilizes at least three or at least four different wavelengths of light for collection of reflectance data where the different wavelengths are longer than 730 nanometers. The three or four wavelengths are utilized to generate a range of reflectance data suited for accurate determination of oxygenated hemoglobin and deoxygenated hemoglobin concentrations. The relatively long wavelengths decrease optical interference from certain dyes, particularly methylene blue and PVPI, which may be present on tissue being analyzed for viability and further enhance the generation of accurate reflectance data. The wavelengths are 760 nanometers, 810 nanometers, and 850 nanometers, or 760 nanometers, 810 nanometers, 850 nanometers, and 900 nanometers.

Oximeter probe with light wavelengths to avoid surgical dyes

The programmable monitoring system comprises one or more motion sensors, one or more temperature sensors, one or more door sensors and one or more pill box sensors. Each sensor is tagged with a unique code readable by a smart phone camera and software program which allows alarms on the smart phone to be set. The alarms are individually set for any or all of the sensors based on habits of the person being monitored.

Programmable monitoring system

A device for monitoring human feet can include: a transmissive sheet configured to bear at least 90 kg supported at a height of no more than 23 cm, and a foot image capture system below the sheet. An optical image sensor can capture a field of view including at least 250 cmof the surface of the sheet. The device can have a central reflective element positioned below the sheet directly above the sensor and two outer mirrors such that two fields of view at least 250 cmeach can be focused onto the sensor by a lens. Foot sole images can be automatically captured when a patient stands on the device. Images can be transmitted to a database and associated with the patient by analyzing the images for a unique predetermined metric.

System and method for continuous monitoring of a human foot

The present invention pertains to a device and method for imaging of a human foot including a transmissive sheet with an upper surface configured to accommodate a sole of the foot, a light source positioned below the sheet for emitting light toward the sheet, and an optical path controller in the sheet or coupled to the sheet for altering a path of the light causing internal reflection of the light toward a predetermined region of the foot. The image can be analyzed for a predetermined characteristic associated with a human patient, and determination made whether the characteristic in the image matches the patient. Brightness in the image can be analyzed for tissue moisture information.

System and method for prevention of diabetic foot ulcers using total internal reflection imaging

The present invention pertains to a method and apparatus for pressure sore detection. A modulated optical signal based on a digital code sequence is transmitted to human tissue. A temporal transfer characteristic is derived from the modulated optical signal. Tissue characteristics is determined based on the temporal transfer characteristic.
