摘要:
Apparatus and method for an analyte determination in blood, relying on spectroscopic techniques, in which sample is illuminated with light having dedicated spectral characteristics. The first light source (20) is a broadband light source in the IR-range, the second light source (25) is comprised of one or more monochromatic sources, such as laser diodes. The sources are chosen to correspond to wavelength highly correlated with glucose adsorption.

Apparatus for determining where to locate a measuring device (3) on skin, the apparatus having a muscle tension sensing device (1) arranged to sense muscle tension at different locations on the skin, and a processor (2) for determining and outputting an indication of where to locate the measuring device on the muscle, based on the sensed muscle tensions. This can help make the skin measurements such as non invasive glucose measurements more consistent, and more accurate.
摘要:
A device for analyzing a material, the device having a photo acoustic generator (40) for generating pressure waves in the material by pulsed illumination by a light source, and a sensor (20, 30, 50) for producing a signal using self mixing interferometry, the signal representing displacements of the material due to the pressure waves, and a signal processor (60) for processing the signal to analyze the material. This combination of photo acoustic stimulation and self mixing interferometry sensing helps reduce or avoid errors or distortions caused by sensor contact on the material, and can provide a better ratio of sensitivity for a given degree of compactness of the device.

The present invention provides a location indicating device (10) for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body. The location indicating device (10) comprises a matrix (7) of electrodes for determining skin resistance at different locations on skin of a human or animal body and a calculating unit (8) for calculating a location with highest skin resistance. The location indicating device (10) furthermore comprises visualisation means (9) for indicating the location of highest skin resistance to a user. The present invention also provides a method for making such a location indicating device (10) and a method for determining on skin of a human or animal body a location for performing measurement of a physiological parameter in and/or treatment of the human or animal body by using such a location indicating device (10).
摘要:
A perfusion, regulation device (10) for regulating tissue perfusion at a target site (2) on a human or animal body. The perfusion regulation device (10) comprises a pressure regulator (4) for determining and regulating pressure exerted by the perfusion regulation device (10) on the target site (2) and a perfusion monitor (5) for measuring tissue perfusion at the target site (2). The perfusion regulation device (10) furthermore comprises a control system (6) for driving the pressure regulator (4) so as to regulate pressure exerted by the perfusion regulation device (10) to the target site (2) thereby using feedback from the perfusion monitor (5). There is also a method for making such a perfusion regulation device (10) and a method for regulating tissue perfusion at a target site (2) on a human or animal body using such a perfusion regulation device (10).
