Abstract: A device for non-invasive measurement of blood pressure includes a blood pressure cuff, a plethysmographic electrode for acquiring an impedance plethysmogram distal to the cuff and a processing device to inflate and deflate the cuff, generate the impedance plethysmogram and to determine the systolic and diastolic blood pressures. It is determined when the cuff is completely occluding the extremity, e.g., by detecting pulses at a second, partially occluded cuff or by a photoplethysmogram attached to the big toe. The device can be used to measure systolic or diastolic blood pressure or both. It can also be used to take ankle-brachial measurements. An autocorrelation technique can be used to correct noise.

Abstract: In a system and method for peripheral impedance plethysmography, an electrode for application to the patient's limb includes two outer current electrodes and two inner voltage electrodes. A distance between the two inner electrodes is automatically input into an analyzing device, either as a pre-stored value or as determined automatically from the electrode. Peripheral blood flow is calculated in accordance with that distance.

Abstract: This device uses electrical impedance and signal processing to measure the small change in volume (“Pulse Volume”) of a limb-segment that occurs with each heartbeat. “Pulsatile Flow” is defined as the pulse volume multiplied by the heart rate and is an index of tissue perfusion. This information can be combined with measured blood oxygen saturation to determine how much oxygen is reaching the tissues. The combination of knowing oxygen saturation and tissue perfusion is far more useful than knowing just one or the other of these parameters.

Abstract: A footwear fastening system and a method of converting lace fastened footwear to hook-and-loop fastened footwear comprising hook-and-loop fastener strips which are secured to the footwear by means of a lace which passes through adjacent eyelets along each upper side of the footwear. The fastener strips are anchored to one upper side with the lace and are passed beneath the lace on the other upper side and tensioned to draw the upper sides together into a snug fit. Tubular posts may be disposed between the eyelets and laced to the upper sides by the lace.

Abstract: A flexible blood pressure cuff for use in measuring the blood pressure of a patient, includes an inflatable bladder having a first side and a second side. One of the bladder sides is provided with hook and loop fasteners for adjustably and removably retaining at least a portion of one of the two bladder sides against a remaining portion of the one bladder side when the bladder is folded over itself. The effective inflatable width of the bladder is thereby adjusted to accommodate the circumference of the limb of the patient so that accurate blood pressure measurements may be obtained for each patient. According to the method, the blood pressure cuff is folded over itself to produce a cuff having an effective inflatable width which is adjusted according to the circumference of the limb of the patient whose blood pressure is to be measured.

Abstract: A method for generating audio information to indicate the presence and nature of a cardiac rhythm disturbance is disclosed. More specifically, this method produces sounds which accompany atrial and ventricular ectopic rhythms, allowing the physician to appreciate the presence of such rhythms without having to visually inspect the morphology of the electrocardiogram signal. Furthermore, the sounds differ according to the type of ectopic rhythm present. This method provides such information in real time, allowing the physician to correlate the information with the current condition of the patient. The electrocardiogram signal is analyzed by a microprocessor or microcomputer which in turn controls a tone generator to produce the audio output.

Abstract: A system and method for measuring the impedance and impedance changes in a body segment are disclosed. By utilizing an ECG buffer, at least one plethysmograph buffer, and concurrently performing at least extraction of an ECG waveform stored in the ECG buffer and extraction of impedance waveforms stored in the at least one plethysmograph buffer, enhanced signal-to-noise ratios of output signals of impedance plethysmographs are achieved. In an embodiment, improved waveform selection using template matching is also achieved. With template matching, a new candidate waveform is compared in shape to the previous average waveform and may be accepted for current averaging based on the comparison.
