摘要： Apparatus for measuring electrolyute concentrations in fluid samples. The apparatus includes an ion selective electrode having a plurality of ion selective detection sites. Each site has an affinity for a preselected electrolyte of interest and generates a potential having a magnitude related to the concentration of the corresponding electrolyte in the sample. A voltage to optical transducer circuit is provided to convert the voltage differentials to optical signals having intensity related to the concentration of the electrolytes in a first embodiment, a digital code related to the concentration of the electrolytes in a second embodiment, and an optical absorption or density value related to the concentration of the electrolytes in a third embodiment. The optical signals are suitable for detection by conventional optical detector apparatus of assay instruments and may be processed using conventional two point linear interpolation techniques to determine the concentrations of the preselected electrolytes.

摘要： This invention relates to a process for making a lightweight article which involves the steps of: (1) feeding a thermoplastic resin composition into an extruder, wherein the thermoplastic resin composition contains (a) from about 94 to about 99 weight percent polyethylene terephthalate, and (b) from about 1 to about 6 weight percent of at least one polyolefin; (2) mixing an inert gas into the thermoplastic resin composition in the extruder while the thermoplastic resin composition is in the molten state; (3) extruding the thermoplastic resin composition containing the inert gas through a sheet forming die to produce a substantially amorphous cellular sheet which contains a sufficient amount of inert gas cells to provide the cellular sheet with a density which is within the range of about 0.4 to about 1.25; and (4) thermoforming the cellular sheet in a heated mold to produce the lightweight article. Dual-ovenable trays and other types of food containers can be made utilizing the process of this invention. It is advantageous to utilize the process of this invention in making such articles because they are lightweight and can be made utilizing less polymeric materials.

摘要： The present invention provides means and methods for noninvasively identifying the blood pressure characteristics in each of the seven types of vessels in the circulatory system, including the central venous pressure (CVP) through a single monitoring system using fluid depletion plethysmography. Known pressure is applied to a body region in increasing amounts to force blood volume from the body region in step-wise fashion through each vessel type. Blood volume depletion for each vessel type is measured by the increasing electrical impedance of the body part during depletion and is plotted against the increasing pressure data. The resulting series of slope changes within the plotted curve reveals the blood pressure for each vessel type. The data obtained may further be used to determine vessel wall compliance/tension as well as standard measurements such as pulse and large artery systolic and diastolic pressure. Release of the applied pressure may then yield similar data by measuring blood volume replenishment against the decreasingly applied pressure during the same diagnostic operation. The method is not dependent on oscillometric or pulsatile measurement methods. The electrical leads of the impedance/volume sensor and the means for applying pressure to the body part are coextensive to ensure accurate indication of blood volume depletion and replenishment in the body region under pressure and may be incorporated into a single integrated structure.

摘要： A patient monitoring system which includes a portable device and a central station. The portable device includes an ECG and a photo-plethysmograph connected to the patient; arrhythmia analysis apparatus; an expert system for determining if a pre-established critical parameter set has been exceeded; and a wireless wide area communication device for automatically contacting the central station via a public cellular phone network when the critical parameter set has been exceeded. When the central station is contacted, the patient's ECG waveforms, measurements, and trends, are sent to the central monitoring station and a two way voice channel between the patient and the central station is automatically opened. The central station includes a computerized facility which has a station from which a clinician can observe the real time data being sent from the patient, the patients historical records and from which the clinician can talk to the patient and activate therapeutic devices attached to the patient such as an external defibrillator, a pacer or an automatic drug infusion device.

摘要： A microprocessor-controlled, oscillometric method for determining a patient's systolic, diastolic, and mean arterial pressure, practiced in a system comprising an inflatable, occluding cuff, a pump and a valve coupled to the cuff, and monitoring apparatus coupled to the cuff adapted to measure cuff pressure and recurring blood-pressure pulsations occurring in the cuff that are caused by each heart contraction occurring in a measurement cycle. Cuff pressure is raised to a level above the patinet's systolic pressure, and progressively reduced in a stepwise fashion to an ending cuff pressure. A fixed number of pulsations are measured and processed at a first and second cuff-pressure step, and a generally lesser number of oscillations are measured and processed at a third and subsequent cuff-pressure steps. The method includes a first artifact rejection technique used to check for false data relative to the formation of each blood-pressure pulsation. Further, the method includes calculating, for each blood-pressure pulsation, the impulse of a force that is exerted upon the patinet's blood from, and during, each heart contraction that occurs in the measurement cycle. An impulse value is stored relative to each pulsation. A second artifact rejection technique is used, beginning at the second cuff-pressure step, to generate a prediction curve for predicting a next, expected-to-be-stored pulsation impulse value for a next, lower cuff-pressure step. The second artifact rejection technique is also used to repeatedly smooth the prediction curve based on the difference between a pulsation's calculated impulse value and its respective predicted impulse value. A final, smoothed curve is generated reflecting a final impulse value for each cuff-pressure step. From the final curve, the desired blood pressure parameters are derived and displayed in the form of arabic numerals by means of an LCD readout.

摘要： An enclosed electrical device (42) includes an electrical circuit (50) having elements (48-68) which lie substantially in and along a plane (115). A member (70) is applied to a one side and a member (85) is applied to another side of the circuit (50) for at least partially enclosing the same. Conductors (48) and (49) of circuit (50) are fixedly penetrated, preferably by pins (74) which are fixedly engaged to enclosure members (70) and (85). Such engagement is advantageously provided by making the pins (74) an integral part of member (70), for example by including pins (74) in a premolded member (70). Such engagement is also advantageously provided by making pin-engaging sockets (94) an integral part of member (85), also for example by including the sockets (94) in a premolded member (85). By a preferred friction fit of pins (74) and sockets (94), the enclosure members (70) and (85 ) and circuit elements (48-68) are sufficiently fixed relative to one another to resist forces applied thereto in service.

摘要： Noninvasive-blood-pressure (NIBP) monitoring apparatus is disclosed which is usable to perform either oscillometric or auscultatory NIBP. The apparatus includes relatively adjustable, noninflatable, pressure-information-providing (PIP) structure usable to apply NIBP-useful pressure to such limb adjacent such vessel. Also included is pressure-changer structure associated with the PIP structure, and operable to adjust the same to a beginning NIBP-useful pressure, and to subsequent NIBP-useful pressures, with such adjustment effecting the availability of pressure information that can be sensed by such sensor structure. The apparatus is preferably constructed for oscillometric NIBP monitoring and includes a reaction band removably fittable on and circumscribingly about the limb of such living subject. The preferred construction is for portable, self-contained, ambulatory usage. Other embodiments include providing an output communicator for sending NIBP-data signals in various outputs including electrical, wireless and optical, and visually perceptible ones.
