Abstract:
A method for assessing fluid flow in a conduit includes sensing the fluid flow with a sensor and generating data from the sensor that relates to the sensed fluid flow. The data is output from the sensor and filtered so that it may be interpreted to characterize the fluid flow. The conduit may be a prosthesis such as stent, a stent-graft or a prosthetic vascular graft and the flow may be any body fluid such as blood, bile, or cerebrospinal fluid.
Abstract:
A method for collecting duodenal juice containing bile under an endoscope is provided. In the method, an endoscope is inserted into a duodenum of a subject from which collection of duodenal juice is performed. In a state in which an illuminating section of the endoscope is stopped at the duodenum, an illumination light is generated. The illumination light has a specific wavelength band capable of displaying a component including bile in an enhanced manner, within a visible wavelength region. By an imaging section of the endoscope, a subject image is captured. The subject image is illuminated by the illumination light of the specific wavelength band. Based on an output signal from the imaging section, a subject information image expressing subject information is displayed in a display section. In the displayed subject information image, duodenal juice containing bile is displayed in an enhanced manner. Then, the duodenal juice is collected.
Abstract:
A method of detecting pathogenic bacteria in the vagina, includes providing a vaginal moisture receiver receivable into the vagina; providing a reactant which changes color when contacted by moisture containing pathogenic bacteria; receiving vaginal moisture on the receiver; and contacting reactant with vaginal moisture on the receiver, whereby a change in color at the receiver indicates the presence of pathogenic bacteria.
Abstract:
A fixed and movable jaw form opposing plates of a capacitor with a paper strip carrying micro amounts of fluid being engaged between the jaws and acting as a dielectric whose characteristics (quality factor Q and relative dielectric constant Er) change depending upon the amount of fluid present on the paper between the jaws. This capacitor is connected with an electronic circuit which includes a digital readout meter. This meter reads the bias current on a transistor, the base of which is connected in circuit with the capacitor thus enabling the quantity of fluid present on the paper to be read out in microlitres.
Abstract:
Provided is an observation apparatus that observes tissues of an organism. The observation apparatus includes a generator that generates first data obtained by irradiating the tissues with a first infrared light with a first wavelength and second data obtained by irradiating the tissues with a second infrared light with a second wavelength being different from the first infrared light in an optical property value with respect to a water, and a comparison calculator that compares the first data with the second data to generate bodily fluid data that indicates a presence of a bodily fluid on a surface of the tissues.
Abstract:
A device, system and method for detecting bile and blood are provided. The device may comprise a housing having a gap through which in-vivo fluids may flow, illumination sources on one side of the gap, a light detector which is facing the illumination sources and is positioned on the opposite side of the gap for detecting light which passes through the in-vivo fluids, and a transmitter to transmit the detected signals generated according to the detected light. The system may further comprise a receiver to receive the detected signals transmitted by the transmitter, and a processor. The method may comprise comparing the detected signals with a predetermined threshold calculated from the transmission spectra of bile and of blood and determining the presence and/or concentration of bile and blood in-vivo.
Abstract:
The invention relates to an embedded bodily fluid analysis device comprising a measuring cell containing the bodily fluid to be analyzed, at least one reference cell containing a reference standard and an electronic measuring circuit. The measuring cell is provided with at least one work electrode of the measuring cell and with at least one reference electrode of the measuring cell. The reference cell is provided with at least one work electrode of the reference cell formed by the same material or materials as a work electrode of the measuring cell and with at least one reference electrode of the reference cell formed by the same material or materials as a reference electrode of the measuring cell.
Abstract:
A system and method of determining the rate of flow of Cerebral Spinal Fluid (CSF) in an External Ventricular Drainage Mechanism (EVDM). Drops, or the flow of CSF moving within or into the EVDM, are detected. The user is provided, in a human-readable form, information derived from the detection. This may be accomplished with a printer and/or a digital display device. The information may include CSF flow rate and/or CSF volume collected in the EVDM, for example. The system and method may further determine if the drops or flow have ceased for at least a certain amount of time. In that case, an alarm may be activated.
Abstract:
Described herein are microprocessors, devices, and methods useful for sweat and/or temperature detection that correlate more closely with changes in amperometric or charge signals related to analyte amount or concentration. The present invention provides methods for the establishment of more accurate sweat and/or temperature thresholds and new methods of compensation, such as correcting for the effects of sweat and rapidly changing temperature on measured analyte values. The present invention reduces the number of skipped or unuseable readings provided by analyte monitoring devices during periods of sweating or changing temperatures. Further, the present invention provides methods for improving the accuracy of reported readings of analyte amount or concentration. In one aspect, the present invention provides passive collection reservoir/sensing devices used in combination with active collection reservoir/sensing devices for detection of sweat and/or temperature related parameters.
Abstract:
Vaginal probe apparatus comprising in combination a longitudinally elongated probe insertible into the vagina for a test purpose; a support operatively connected with the probe projecting away from the support, the support including a manually manipulable handle; and an edge presented generally longitudinally for limiting probe insertion into the vagina.
