摘要： Exemplary embodiments provide an optical penile blood flow measuring technology for the monitoring of neurological and vascular function of structures at surgical risk. The measuring principle is to rely on optical absorption properties of blood components for penile blood flow monitoring. Certain embodiments use different wavelengths to measure changes in hemoglobin concentrations and are particularly advantageous in continuous, autonomous monitoring with real-time feedback to surgeons for potential intervention and decision-making in a timely manner. The measurements results can be used to provide real-time feedback to surgeons operating on the patient, or for off-line analysis and evaluation. Certain embodiments can operate autonomously in the continuous measurement mode, a synchronized mode, or a triggered mode, reducing the need of highly-skilled apparatus operators, allowing automatic and real-time warning to surgeons when operating in areas while preserving the functions of critical nerves, resulting in improved clinical outcomes and reducing operation costs.

摘要： Systems, methods, apparatuses, and medical devices for harmonizing data from a plurality of non-invasive sensors are described. A physiological parameter can be determined by harmonizing data between two or more different types of non-invasive physiological sensors interrogating the same or proximate measurement sites. Data from one or more first non-invasive sensors can be utilized to identify one or more variables that are useful in one or more calculations associated with data from one or more second non-invasive sensors. Data from one or more first non-invasive sensors can be utilized to calibrate one or more second non-invasive sensors. Non-invasive sensors can include, but are not limited to, an optical coherence tomography (OCT) sensor, a bio-impedance sensor, a tissue dielectric constant sensor, a plethysmograph sensor, or a Raman spectrometer.

摘要： An electronic device including optical sensing with a concentric architecture and methods for operation thereof is disclosed. The concentric architecture can include light detector(s) arranged in a concentric manner around light emitter(s). In some examples, at least one light emitter can be located in the center of the device, and each light detector can be located the same separation distance from the light emitter. Each light detector can be arranged such that the separation distance from the centrally located light emitter can be greater than the separation distance from another light emitter. Examples of the disclosure further include a selective transparent layer overlaying the light detector(s). The selective transparent layer can include section(s) transparent to a first wavelength range and non-transparent to a second wavelength ranges. In some examples, the selective transparent layer can further include section(s) transparent to the second wavelength range.

摘要： Blood pressure signals are reconstructed from PhotoPlethysmoGraphy (PPG) signals by: receiving PPG signals including systolic, diastolic and dicrotic phases; and determining first and second derivatives of the PPG signals and: a first set of values indicative of lengths of the signal paths of the PPG signal, the first derivative and the second derivative thereof in the systolic, diastolic and dicrotic phases; a second set of values indicative of relative durations of the PPG signal and the first and second derivatives thereof in the systolic, diastolic and dicrotic phases; and a third set of values indicative of the time separation of peaks and/or valleys in subsequent waveforms of the PPG signal. Reconstruction also includes applying artificial neural network processing to the first, second and third set of values. The artificial neural network processing includes artificial neural network training as a function of blood pressure signals to produce reconstructed blood pressure signals.

摘要： A method of adjusting a staple parameter of a surgical stapling instrument is disclosed. The method includes determining, by a control circuit of the surgical stapling instrument, a first stroke length for a first staple driver of the surgical stapling instrument to drive a first row of staples of a circular stapling head assembly of the surgical stapling instrument; detecting, by the control circuit, a malformed staple in the first row of staples; adjusting, by the control circuit, the staple parameter, based on the detection of the malformed staple; and determining, by the control circuit, a second stroke length for a second staple driver of the surgical stapling instrument to drive a second row of staples of the circular stapling head assembly.

摘要： Surgical systems are disclosed. Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

摘要： The disclosed embodiments provide a system that non-invasively analyzes blood flow in a sample of living tissue. During operation, the system obtains light from a temporally coherent source, and splits the obtained light between a reference path and a sample path. Next, the system multiply scatters light from the sample path by passing the light through the sample. The system then recombines light from the reference path and the multiply scattered light from the sample path. Next, the system uses a sensor array to detect an interference pattern resulting from the recombination. Finally, the system analyzes signals from the sensor array to determine a blood flow in the sample.
