    摘要: A measuring instrument utilizing surface plasmon resonance is described. The instrument employs no moving mechanical part because it produces the resonance by changing the parameters either electrically or acoustically, and it detects the reflection by a stationary detector.

    摘要: A method and apparatus for detecting the presence and/or concentration of biomolecules, in particular DNA, by providing a boundary surface between an optically denser medium and an optically rarer medium. Biomolecules adsorb to the boundary surface and alter the characteristics of impinging light. The method and apparatus use surface plasmon resonance (SPR) to excite the biomolecules. The angle of incidence of the impinging light is maintained at the angle at which SPR occurs, thereby controlling the energy transferred to the biomolecules. The energy transferred to the biomolecules causes the biomolecules to generate excitation light which is reflected and monitored at the boundary surface. The angle of incidence is controlled by rotating a desk such that the intensity of the reflected light is always maintained at a minimum which ensures that the angle of incidence is equal to the angle at which SPR occurs.

    摘要: The presence of trace materials in a sample is detected using both macroscopic and microscopic properties. A detector includes a light source and an optical resonator. The light source may be located either inside the resonance cavity of the resonator or outside the cavity, in which case it may be a semi-conductor such as a semi-conductor laser or a superluminescent diode. The detector also includes at least one reflective member that has a total internal reflection (TIR) surface and may be a passive device or an active gain element. Light from the light source is preferably focussed onto a single point of reflection on the TIR surface. The test sample is positioned within the evanescent field region of the TIR surface. Optical changes arising within the evanescent field region, such as excitation of fluorescence in the sample, changes in its refractive index, and changes in the resonant frequency of the optical resonator, are then detected. These changes are then sensed to determine the amount or at least presence of analyte located at the TIR surface.

    摘要: A monitor for the automated non-invasive measurement of a patient's blood pressure comprising apparatus for automatically inflating and deflating a cuff which is to be applied around a patient's extremity, first and second pressure sensors coupled to the airway of said cuff, each providing an electronic signal indicative of cuff pressure, and a processor responding to the signals obtained by said pressure sensors for stopping the inflation of the cuff when a maximum cuff pressure is reached, and for calculating the blood pressure from the oscillations of the pressure signal. A memory is connected to said processor in which calibration values indicating the pressure related to the electronic signals provided by each of said two pressure sensors are stored. The processor is adapted to access and compare those calibration values which correspond to the actual values of said electronic signals provided by said two sensors to monitor supply and/or reference voltages, and to cause the deflation of the cuff when the actual calibration values differ from each other or the supply and/or reference voltages each differ from a related predetermined value more than a predetermined amount, thus preventing any pressure raise over predetermined limits in case of any malfunction of the monitor without the use of mechanical pressure switches.

    摘要: In a cardiac monitoring method, at east an inactive natriuretic peptide (22) and an active natriuretic peptide (20) are assayed in a biological sample taken from a patient. Both the inactive and active natriuretic peptides are produced in the patient responsive to cardiac stress. A therapeutic agent (26), such as a synthetic or mimetic natriuretic peptide, is administered to the patient. The administered therapeutic agent substantially interferes with the active natriuretic peptide assay but does not substantially interfere with the inactive natriuretic peptide assay. Kinetics of the administered therapeutic agent are determined based on at least the active natriuretic peptide assay. Cardiac diagnostic information is determined based on at least the inactive natriuretic peptide assay.

    摘要: A pneumatic connector for an automated non-invasive blood pressure monitor having a connector body (1) containing two oppositely arranged hollow cavities (8) for insertion of a differential pressure sensor in each cavity. The hollow cavities are connected by a bore (10) which is in connection with the main airway (6,7) in the connector body (1).
