  • Patent number: 7048687
    Abstract: A limited use medical probe is disclosed, including a memory for maintaining a use value. The medical probe is coupled to a medical device that inhibits its function when the use value reaches a predetermined threshold value, preventing improper use of the probe. The probe memory may also store identification, usage, and clinical data. A probe auto-identification function, a probe re-identification function and a probe functional test sequence are disclosed for the medical probe. After use, a reprocessing step may reset the probe memory, permitting further probe use.

  • Patent number: 6733447
    Abstract: The invention relates to a medical parameter monitoring device which allows the monitoring of a plurality of medical parameters from a remote location. The invention uses a central monitoring system which transmits and receives date parameters via RF from remote patient monitors. The monitoring system utilized a digital spread spectrum RF transceiver between the central monitoring system to the remote monitors. Forward error correcting, frequency hopping, and spread sprectrum communications are employed to provide accurate transmission of data for a plurality of physiological parameters. Transmitted data can be automatically registered into storage in the central monitoring system.

  • Patent number: 6647280
    Abstract: A signal processing method, preferably for extracting a fundamental period from a noisy, low-frequency signal, is disclosed. The signal processing method generally comprises calculating a numerical transform for a number of selected periods by multiplying signal data by discrete points of a sine and a cosine wave of varying period and summing the results. The period of the sine and cosine waves are preferably selected to have a period substantially equivalent to the period of interest when performing the transform.

  • Patent number: 6526301
    Abstract: An oximeter for non-invasively measuring the oxygen saturation in blood with increased speed and accuracy is disclosed. The oximeter includes a number of features which increase the functionality of the device including: a dynamic range control for monitoring a range of inputs from low level signals encountered in fetal and other applications to typical or high level signals; light emitting devices of different wavelengths for filtering noise and providing additional medial monitoring functions; and an improved method for calculating the oxygenation levels without the need to take peak and valley measurements. The device includes a sensor unit which can be attached to a patient and an oximeter which determines the oxygen saturation in the blood based on signals received from the sensor. The sensor can include light emitting devices in three or more wavelengths to provide additional functions. In the present invention, the detected signal is immediately converted to a digital value.

  • Patent number: 6449501
    Abstract: An improved pulse oximeter is disclosed. The pulse oximeter includes audio signal generation means, controlled by algorithms in a processing element which continuously transform the signals from the sensor into signal quality information. This information is converted into an audio signal and annunciated for the operator's use in guiding sensor placement. This signal quality information is available even in the absence of successful computation of pulse rate and/or oxygen saturation level. It furthermore can reflect signal quality changes that may be too subtle to be reflected in the typical numerical representation of pulse rate and oxygen saturation trend. The audio representation of the signal quality can further be modulated to convey other system and/or physiological status and alerts.

  • Patent number: 4686999
    Abstract: The ventilation monitor of this invention includes a plurality of discrete sensors and a plurality of independent channels for processing the input signals from each of the discrete sensors. The principle category of sensor used in conjunction with this ventilation monitor is capable of the reception of information associated with breathing and cardiovascular movement. A second category of the sensor used in conjunction with this ventilation monitor is capable of the reception of audible sounds associated with breathing. Each of the individual input signals from these sensors is initially verified as being indicative of the sensation being monitored and, thereafter, compared in real time with one another and criteria stored within a microprocessor. The purpose of the comparison is to verify a normal breathing pattern and signal an alarm when the breathing pattern is abnormal.

  • Patent number: 4583553
    Abstract: An ambulatory cardiac analyzer and recorder includes an allocation and priority scheme which has quotas for classes of QRS events and priority between types of events within a class. The quality of a low priority event is used to replace a similar type of event when the memory is full. The peak detection, QRS identification and classification circuit process and correlate information from both of two input channels. This allows quicker and more accurate determination of QRS waveforms as well as typical QRS waveforms.
