Abstract: A blink detection apparatus includes an eyelid state index value measurement unit configured to chronologically measure an eyelid state index value, and a signal processing device. The signal processing device is configured to determine that a blink occurs when a change width of the measured eyelid state index value from a baseline that is a reference value of the eyelid state index value in a case where eyelids are in an opened state exceeds a magnitude of a threshold from the baseline, to count the number of times when the change width of the measured eyelid state index value from the baseline exceeds the magnitude of a tentative threshold from the baseline, and to set the threshold to a tentative threshold at which change in the number of times with respect to the tentative threshold is minimal.

Abstract: Provided is an improved medical elongated body which can be inserted into a biological lumen and can be restrained from unintentionally moving at a target site inside the biological lumen. The medical elongated body includes a main body portion that extends in an axial direction, and a projection portion that protrudes radially outward on an outer circumference of the main body portion and extends in the axial direction. One surface of the projection portion in a circumferential direction has higher sliding properties than an other surface of the projection portion in the circumferential direction.

The finger blood pressure cuff may include a housing having an opening sized to receive a human finger and an inflatable elastic bladder disposed about an inward-facing surface of the opening. The inflatable elastic bladder may be inflated to pressurize a user's finger and temporarily occlude blood flow in the user's finger. The finger blood pressure cuff may include a pressure sensor for obtaining blood pressure measurements.

Abstract: A system and method for determining the breathing rate of a patient using only an oscillometric device as the physiological sensor. Here, the oscillometric device is mounted on a patient's limb, and oscillometric pulse waveforms are obtained as the device's cuff deflates, thus obtaining pulse wave signals and artifact signals over multiple patient breaths. A computer processor analyzes these signals, and removes artifacts according to various algorithms. The resulting signal can be viewed as containing both an amplitude modulated envelope of pulse waves (AM signals) and a frequency modulated sequence of pulses at various time intervals (FM signals). The main harmonics of the AM and FM signals both contain breathing rate data, and system accuracy can be improved by comparing the AM harmonics with the FM harmonics. The final breathing rate data, often a function of the AM and FM harmonics, is output or stored in memory.

Abstract: A method of measuring a patient's systolic and diastolic brachial blood pressure non-invasively with a brachial cuff considers the shape of a patient's peripheral waveform (e.g., the cuff volumetric displacement waveform) to recalibrate the height of the waveform. The maximum and minimum values of the recalibrated waveform correlate to and closely estimate counterpart values for invasively measured brachial systolic and diastolic pressure.

Abstract: An aspect of the disclosure pertains to a blood pressure measurement device and methods of obtaining pulse information from a blood pressure measurement. An inflatable bladder defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage, where the inflatable bladder is inflated to a pressure greater than a maximum amplitude pressure from oscillometric data in a pressure profile. The inflatable bladder may be deflated and then re-inflated to a target pressure and held at the target pressure to generate pulse information, or the inflatable bladder may be deflated to the target pressure and held at the target pressure to generate the pulse information.
