摘要: The present disclosure generally relates to methods of using near infra-red radiation, such as from a near infra-red spectroscopy device, to monitor physical activity in a person. In one aspect, a method of measuring physiological parameters is provided. The method further includes determining a NIRS-derived measure of a tissue of a person using near infra-red spectroscopy over a time period, associating the NIRS-derived measure to the time period to determine a function-related change, and associating the function-related change to a biomechanical function.

摘要: An analyte monitoring system may include one or more of an analyte sensor, a transceiver, a display device, and a management system. The transceiver may be configured to receive sensor data from the analyte sensor and calculate analyte monitoring information. The display device may be configured to receive the analyte monitoring information from the transceiver. The management system may be configured to receive analyte monitoring information from the display device. The management system may be configured to use the analyte monitoring information to produce a comparison result. The management system may be configured to, based on the comparison result, transmit to the display device management information associated with the received analyte monitoring information. Producing the comparison result may include comparing one or more performance diagnostics with one or more performance indicators. Producing the comparison result may include comparing compliance information with usage protocol information.

摘要: An optical imaging device and system can be used to visualize and/or provide a quantitative measure of changes in patient vasculature, for example, to monitor responsiveness of a tumor to a particular chemotherapy treatment. A plurality of detectors (e.g., two) are spaced from a plurality of substantially monochromatic light sources (e.g., four) on an interrogation face of the handheld device. Wavelengths of light in the near-infrared range are used to measure the content of hemoglobin, water, and lipid of the tissue that the interrogation face comes in contact with. The light can be modulated so that the effect of ambient light is not minimized or at least reduced. The detected signal is amplified, filtered, and digitized within the device by appropriate electronics. In embodiments, handheld device can include a wireless communication module, such as a Bluetooth device, for wireless transmission of data to/from the remote processor or computer.

摘要: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.
