A method and system for measuring oxygen levels and various blood constituents utilizing a sensor having one or more light sources, and one or more light detectors is disclosed. The system is capable of using data collected by the one or more detectors from a non-monochromatic light source to provide accurate information during motion events occurring with an extremity the sensor. The system is also capable of detecting and providing an alert if the sensor is not properly placed on a patient or becomes disengaged therefrom.

A pressure sensing clip (1) and a system including a bandage (19) for detecting and displaying the pressure applied by a (compression) bandage (19) to a human or animal body in which the pressure sensing clip (1) has an inner bandage penetrating arm (2) and an outer arm (3) hingedly attached to the inner arm (2) at a hinge (4) so that the outer arm (3) is movable between a hingedly closed position with respect to the inner arm (2) and a hingedly open position. The device can be operatively attached to an applied compression bandage, or it can be placed beneath or between the bandage during bandage application so that the bandage covers the sensing part of the device. In the latter application, the ability of the arms of the device to adapt an open configuration allows the bandage to be applied over the inner arm leaving the outer arm to close once the bandage has been applied. The device can receive, store and transmit data to a user.

In an embodiment, a light source comprises LEDs and super-luminescent LEDs. The light source emits light at at least wavelengths of about 1610 nm, about 1640 nm, and about 1665 nm. In an embodiment, the detector comprises a plurality of photodetectors arranged in a special geometry comprising one of a substantially linear substantially equal spaced geometry, a substantially linear substantially non-equal spaced geometry, and a substantially grid geometry.

An activity monitoring device and associated methods for using and interfacing with the activity monitoring device are provided. In one example, the activity monitoring device includes a housing configured for attachment to a body part of a user. Also included ins a display screen attached to the housing and a sensor for capturing physiological conditions of the user. The sensor is disposed along a surface of the housing so that the sensor is proximate to the body part, the body part having at least some exposed skin. The activity monitoring device also includes memory for storing the captured physiological conditions, and a processor for examining the captured physiological conditions. At a particular time, the processor automatically selects an application to execute from a plurality of applications based on characteristics of the captured physiological conditions.

Systems, devices and methods for noninvasive analysis of tissue, by irradiating a surface of the tissue with infrared radiation such that an interaction of the radiation with a component of the tissue other than water in two spectral bands is substantially identical, measuring an intensity of the radiation that emerges from the tissue in each of the spectral bands, determining change in at least one of shape and intensity of signals received by the at least one radiation detector, calculating a relative absorption by the tissue of radiation in one of the first and second spectral bands relative to absorption by the tissue of radiation in the other of the first and second spectral bands, and determining concentration of a predetermined substance, in accordance with the calculated relative absorption and in accordance with determined change in the received signal.

A device for measuring brachial arterial blood pressure in an individual has a blood pressure cuff attachable to an upper arm, means, separate to the blood pressure cuff, for measuring the heart rate, and a control unit connected to both the blood pressure cuff and the heart rate monitoring means, such that, in use, the control unit monitors the heart rate for the establishment of a stable resting heart rate, initiates a blood pressure measurement, and calculates the pulse pressure (PP) to establish the status of the brachial artery during the blood pressure measurement. Where the heart rate drops to within +12 bpm of a reference, resting heart rate for the individual the device will initiate a blood pressure measurement in accordance with a reference, resting heart rate protocol. However, where an irregular heart rate (IRHR) is found the device will initiate a blood pressure measurement in accordance with a timed protocol.

A computer-implemented method is described. The computer-implemented method is used for populating data of a graphical user interface (GUI). The computer-implemented method includes generating one or more graphical elements of one or more activities captured by a monitoring device. The monitoring device is usable by a user during the capturing. The method further includes generating a timeline including a time period over which the activities are performed. The timeline includes a chronological order of time within the time period. The method further includes generating an activity symbol for one or more of the activities performed during the time period. The activity symbol has an image that is graphically overlaid on the graphical elements of the activities.

A sweat sampling and sensing device for sensing sweat on skin includes an analyte-specific sensor for sensing a first analyte in sweat; a sweat collector placed on or adjacent to skin with a plurality of pores or pathways for entry of sweat from skin into said sweat collector, said sweat collector at least partly defining a sweat volume between said analyte-specific sensor and the skin; and a pressure element capable of holding said sweat collector against the skin with a pressure and reducing the sweat volume between said sweat collector and the skin.

A fluid titration system has an optical sensor, a physiological monitor, a titration controller and an infusion device. The optical sensor transmits multiple wavelengths of light into a tissue site of a person and detects the optical radiation after attenuation by pulsatile blood flowing within the tissue site. The physiological monitor receives a resulting sensor signal and derives a plethysmograph that corresponds to the pulsatile blood flow. The monitor also calculates a plethysmograph variability measure that is responsive to changes in perfusion at the tissue site. A titration controller generates a fluid control output according to the variability measure. The infusion device administers a liquid solution via an intravenous (IV) connection to the person according to the fluid control output so as to regulate at least one of a fluid flow start, rate and stop.

A clip system relates to a sealed package having a picture or motivational item and a clip. The picture or motivational item has a double sided sticky adhesive with a protective layer. The protective layer is then removed and applied to a surface. The device can be applied to needles to help people overcome their fear. The device may also be applied to needles, heart monitors, walls and other surfaces. Various clips for holding medical instruments are also enabled.
