    摘要: This invention relates to the non-invasive determination of the degree of vasoactivity in the microcirculation in a tissue caused by a drug, disease, injury normal or pathological regulation. More specifically, the invention relates to a method of determining the influence on microcirculation in living tissue from an irritative agent, drugs, disease, injuries normal or pathological regulation including, illuminating a tissue surface with polarized light, collecting the backscattered light through a polarizing filter, detecting the backscattered and polarized light by a photo-sensitive array, transferring the collected information in digital form to a computing device, separating the collected information into at least two data matrixes, each representing a specific wavelength range and generating an output data matrix by processing corresponding values in at least two data matrixes by an algorithm, wherein each value in said output data matrix represents the amount of influence on the microcirculation in a source point of the tissue. Thereby a representation of the tissue microcirculation is obtained.

    摘要: In a method and an apparatus for measuring the superficial blood flow in tissue, a section of the tissue is irradiated with monochromatic light from a laser source. Light scattered by moving blood cells and adjacent stationary structure within a part of the irradiated section is collected and passed to a photo-detector arrangement, which produces an output signal containing fluctuating signal components, a Doppler signal, deriving from interference between light components having differing frequencies due to having been scattered by moving blood cells and thereby subject to frequency shifts. The Doppler signal contains information concerning the number of blood cells present and the velocity at which they move. By means of a signal processor, there is derived from the Doppler signal a signal which is linearly related to the blood flow expressed as the product of the number of blood cells and their average velocity of movement, and a signal which is linearly related to the number of blood cells present.

    摘要: The present invention relates to a device for connecting two electrical circuits (2,17;15,16) by a connection which permits that the two circuits easily can be separated and reunited again at the same time as interference and scratching noise in the connection mechanism are avoided. A first carrier (14, 28) is movable around a shaft (1), which is fastened onto a second carrier (7, 29). The first carrier (14, 28) can easily be removed from the shaft (1) and refitted again. The first carrier (14, 28) has a projecting part (8, 23, 30), which presses against an electrically conducting elastomer (4,18a-l, 21, 33) localized on the second carrier (7, 29). On the projecting part (8, 23, 30) there is an electrically conducting part (9, 20a-l, 24a-h), which is connected to a first electrical circuit (2,17) localized on the first carrier (14, 28). The electrically conducting elastomer (4,18a-l, 21, 33) is connected to a second electrical circuit (15,16) localized on the second carrier (7, 29). By means of co-operation between the projecting part (8, 23, 30) and the elastomer (4,18a-l, 21,33), an electrical connection between the first (2,17) and the second circuit (15,16) is achieved.

    摘要: The invention is directed to a system for the measurement and presentation of flow movements in a fluid to determine blood perfusion in superficial blood vessels of a body organ. The system includes a laser light source (1) generating a laser beam, apparatus for directing the laser beam onto a body part to be examined and for guided movement of the beam over the body part. The beam is moved over the body part in a predetermined scanning pattern (8). The system further includes a receiving part for the beam reflected from the body part, and apparatus for detecting broadening of the frequency of a reflected light beam caused by a Doppler effect. This results in measuring the magnitude of superficial blood circulation in the body part (5) at points scanned by the beam.

    摘要: The invention relates to a method and to a system for reducing the distance-dependent amplification factor when measuring fluid flow movements with the aid of an image-producing laser-Doppler technique, in particular when measuring blood perfusion through tissue. A laser beam source (1) directs a laser beam (2) onto a measurement object (5), which scatters and reflects the beam (2). The reflected light is received by a detector (9) which senses the broadening in frequency caused by the Doppler effect. One or more lenses (12: 15, 16) are placed in the path of the beam (2) and are intended to maintain constant the number of coherence areas on the detecting surface of the detector and independent of the distance between detector and measurement object.
