摘要:
An adherent patient device is configured to adhere to the skin of the patient and measure electrocardiogram data, impedance data, accelerometer data, blood oxygen data and temperature data. The adherent device can communicate wirelessly with gateways and a local processor system, such that the patient can wander about the hospital and update the monitoring station with the patient data when the patient is ambulatory. The local processor system can be configured to customize alerts for the patient, for example to notify automatically a specialist in response to a special condition of the patient. The adherent device may comprise a unique adherent device identifier such that the customized alert can be sent based on the unique device identifier. Each of the gateways can be carried and may comprise a unique gateway identifier, such that the unique device identifier and the unique gateway identifier can be used to locate the ambulatory patient.
摘要:
Techniques for non-invasive blood pressure monitoring are disclosed. Data corresponding to a patient may be received from a hospital information system. The data may include, for example, drug administration data, medical procedure data, medical equipment data, or a combination thereof. Whether a blood pressure monitoring system needs to be recalibrated may be determined, based at least in part on the received data. If it is determined that the blood pressure monitoring system needs to be recalibrated, the recalibration may be performed and at least one blood pressure measurement of the patient may be computed using the recalibrated blood pressure monitoring system.

There is provided a monitor (10) that monitors a state of an organism internal part from the surface of the organism. The monitor (10) includes a probe (23) including an observation window (21) attached to the organism surface (2), a unit (25) that emits a laser onto at least part of an observation region (3) on the organism surface (2) accessed via the observation window (21), a unit (27) that detects scattered light 28 caused by emission of the laser from each of a plurality of observation spots that are dispersed in two dimensions in the observation region (3), a Doppler analyzing unit (51) and a SORS analyzing unit (52) that limit, based on the scattered light 28 obtained from the plurality of observation spots, to first observation spots out of the plurality of observation spots where it is evaluated that scattered light including information on a target part of the organism internal part is obtained; and a CARS analyzing unit (53) that acquires spectra of at least one component from the first observation spots or peripheries of the first observation spots and outputs first information showing the state of the organism internal part based on intensities of the spectra.

An optical method for determining morphological parameters of a tissue lesion comprises: generating a reflectance image of the lesion using an optical transfer diagnosis device; and determining a lesion border, a size of the lesion, a histogram width that gives a measure of inhomogeneity of the reflectance image of the lesion, a relative moment of inertia of the lesion, a center distance representing a physical distance between a geometrical center of the lesion and a center of mass of absorptance, a fractal dimension of the lesion that describes the complexity of its border, an asphericity of the lesion, a relative border length of the lesion, and, optionally, a darkness of the lesion defined as an average value of the reflected intensity of the lesion.
摘要:
A system for continuously monitoring the blood pressure of a patient over an extended time interval requires using a blood pressure measuring unit (e.g. a sphygmomanometer) to calibrate an oximeter. Specifically, the oximeter is used to continuously detect and measure amplitudes for each blood flow pulse of the patient. Periodically, the sphygmomanometer is used to measure blood pressures (systolic and diastolic) in an artery of the patient. Immediately after the measurement cycle is completed, a computer correlates the measured systolic pressure with the pulse amplitude that is detected by the oximeter. Thereafter, the pulse amplitudes that are detected by the oximeter are used as indications of variations in the systolic pressure during the extended time interval that follows.
摘要:
A device for extracting physiological information indicative of at least one vital sign of a subject from detected electromagnetic radiation transmitted through or reflected from a subject comprises an input interface for receiving a data stream of detection data derived from detected electromagnetic radiation transmitted through or reflected from a skin region of a subject. The detection data comprises wavelength-dependent reflection or transmission information in at least two signal channels representative of respective wavelength portions. A signal mixer dynamically mixes the at least two signal channels into at least one mixed signal. A processor derives physiological information indicative of at least one vital sign from the at least one mixed signal, and a controller controls the signal mixer to limit the relative contributions of the at least two signal channels mixed into at least one mixed signal and/or the rate-of-change at which said relative contributions are allowed to dynamically change.
摘要:
In medical imaging, a fiducial marker facilitates tissue image correlation that allows for image analysis, normalization and correction of the optical exposure and spectral and spatial distribution in order to compensate for the surface reflections, sub surface tissue interactions and spatial orientation of the excitation and imaging axes to the subject tissue. Using a cross comparison, clinicians can model tissue image data in different forms in order to reference and compare data from various spectral components and or from different images. This may enhance human interpretation between images including the variations between images even when the spectral, spatial and optical conditions or the image resolution or sensitivity are compromised. Such may be used to assess cosmetic, moisturizing, therapeutic materials and treatments.

摘要:
A subject observation system includes primary light sources (5, 6), a wavelength converting section (12), an image acquiring section (3), a mode input section (13), and a light source section (2). The wavelength converting section (12) converts wavelengths of plural primary light of different wavelengths emitted from the primary light sources, respectively. The light source section (2) successively lights the primary light sources to successively irradiate the observation target with the plural illuminating light from an aperture of a same position, when a special light observation mode to emphasize and display a specific observation target in the observation target is input into the mode input section. The image acquiring section (3) acquires the images every time the observation target is irradiated with respective illuminating light, and generates a special light observation image of the observation target based on the images.
