Patent number: 5860918Abstract: A medical monitoring device includes a system for monitoring and recording physiological parameters of a patient. The monitored physiological parameters are compared by a comparator with a predetermined threshold or an alarm limitassociated with the respective physiological parameter, the presence of an event being detected, if a physiological parameter exceeds the associated threshold or the associated alarm limit for a predetermined period of time, depending on an operation mode set by a user. If the presence of an event is detected, the fact that an event was detected, the parameter value which caused the event and, optionally, further recorded parameter values as well as the respective time at which the event was detected are stored in a memory. Finally, the medical monitoring device includes a display on which a representation of the events which were stored during a predetermined, preceding period of time is produced in relation to time.Type: GrantFiled: April 21, 1997Date of Patent: January 19, 1999Assignee: Hewlett-Packard CompanyInventors: Thomas Schradi, Gerhard Tivig

Patent number: 5860919Abstract: A monitoring method is disclosed which provides for inducing an active pulse in a blood volume of a patient. The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio. This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system. Radiation which passes through the fleshy medium is detected by a detector which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.Type: GrantFiled: April 17, 1997Date of Patent: January 19, 1999Assignee: Masimo CorporationInventors: Esmaiel Kiani-Azarbayjany, Mohamed Kheir Diab, James M. Lepper, Jr.

Patent number: 5857462Abstract: Methods and apparatus for determining in a biological material one or more unknown values of at least one known characteristic (e.g. the concentration of an analyte such as glucose in blood or the concentration of one or more blood gas parameters) with a model based on a set of samples with known values of the known characteristics and a multivariate algorithm using several wavelength subsets. The method includes selecting multiple wavelength subsets, from the electromagnetic spectral region appropriate for determining the known characteristic, for use by an algorithm wherein the selection of wavelength subsets improves the model's fitness of the determination for the unknown values of the known characteristic. The selection process utilizes multivariate search methods that select both predictive and synergistic wavelengths within the range of wavelengths utilized. The fitness of the wavelength subsets is determined by the fitness function F=f (cost, performance).Type: GrantFiled: July 24, 1995Date of Patent: January 12, 1999Assignee: Sandia CorporationInventors: Edward V. Thomas, Mark R. Robinson, David M. Haaland

Patent number: 5853364Abstract: A method and apparatus for reducing the effects of noise on a system for measuring physiological parameters, such as, for example, a pulse oximeter. The method and apparatus of the invention take into account the physical limitations on various physiological parameters being monitored when weighting and averaging a series of measurements. Varying weights are assigned different measurements, measurements are rejected, and the averaging period is adjusted according to the reliability of the measurements. Similarly, calculated values derived from analyzing the measurements are also assigned varying weights and averaged over adjustable periods. More specifically, a general class of filters such as, for example, Kalman filters, is employed in processing the measurements and calculated values. The filters use mathematical models which describe how the physiological parameters change in time, and how these parameters relate to measurement in a noisy environment.Type: GrantFiled: June 7, 1996Date of Patent: December 29, 1998Assignee: Nellcor Puritan Bennett, Inc.Inventors: Clark R. Baker, Jr., Thomas J. Yorkey

Patent number: 5851179Abstract: A fetal pulse oximeter sensor mounted on a sensor head with an articulating design. A lumen on one side of the sensor has a cable or rod therein to either push or pull that side of the sensor with respect to the main body, thus causing the sensor head to articulate. This can be used, for instance, to apply pressure against the fetus' scalp, with the sensor head, using the articulating mechanism, until an adhesive takes hold. Additionally, the sensor may be held in place on the fetus by an adhesive which is appropriate for a wet surface. The adhesive has the characteristics of having sufficient adhering characteristics to maintain the sensor in place, while at the same time not damaging the fetus' skin upon removal, without requiring suction.Type: GrantFiled: October 10, 1996Date of Patent: December 22, 1998Assignee: Nellcor Puritan Bennett IncorporatedInventors: Carl Ritson, Paul Mannheimer, Mitchell Levinson, James R.

The flexible sheet includes a non-conductive lower internal portion (or "sole") and a non-conductive upper/external portion (or "back"). At least the lower portion is a sole (14) provided with a row of cavities and which forms the contact surface. The cavities contain the conducting gel which is applied to the skin. The generally flat turns of the coil are arranged in a sandwich configuration between the openwork sole (14) and the back.Type: GrantFiled: January 31, 1997Date of Patent: December 15, 1998Inventor: Gabriel Bernaz

Patent number: 5846190Abstract: A pulse oximeter has several processing channels for measurement signals which are measured during the switched-on phase of transmission diodes and which are used to determine the oxygen saturation (SpO.sub.2) of a patient. An additional measurement channel processes an ambient light signal which was measured while the transmission diodes were switched off or their intensity modified, in the same way and thus provides a measure of the spectral composition of the ambient light interference. A useful-to-noise-signal ratio (NSV) is derived from the ambient light signal and a measurement signal, which represents a measure of the signal quality and which can be compared with threshold values (G), where an alarm is triggered if the value falls below the threshold values.Type: GrantFiled: October 10, 1996Date of Patent: December 8, 1998Assignee: Hewlett-Packard CompanyInventor: Dieter Woehrle

Patent number: 5843074Abstract: An improved non-coherent pulsed and colored light stimulation device used for therapeutic effects in living creatures. Pulsed/colored light is applied to local areas, or acupuncture macro or micro systems, by means of a small diameter optic fiber (10) housed in a pen-like handpiece (18) which makes application comfortable and precise. The light source is an adjustable rate strobe (4) with a housing attached to the front (6) which allows color gel slides (12) to be interchanged. The light passes through the slides (12) and through a length of jacketed flexible optic fiber (10) where it becomes visible again at the radiant tip (20) of the handpiece (18).Type: GrantFiled: March 17, 1997Date of Patent: December 1, 1998Inventor: Tony Cocilovo
