摘要: A wearable ultrasound patch may include one or more layers, including a backing layer, a transducer layer, a matching layer, and an adhesive layer. The matching layer may include liquid-metal microdroplets dispersed within an elastomer. A volume loading and/or diameter of the liquid-metal microdroplets may tune the acoustic impedance of the matching layer such that the matching layer may provide acoustic matching via a geometric mean between an acoustic impedance of piezoelectric elements of the transducer layer and a skin on which the wearable ultrasound patch is worn. The wearable ultrasound patch may be used in a system with a pulser-receiver.

摘要: An ultrasound measurement device includes: a processing device and multiple ultrasound sensors that capture tomographic information of a physiological structure. The ultrasound sensors include a first ultrasound sensor including a first transducer having a first frequency response with a first resonant frequency, and a second ultrasound sensor including a second transducer having a second frequency response with a second resonant frequency different from the first resonant frequency. The first frequency response partially overlaps with the second frequency response. The second transducer transmits an ultrasound signal that is reflected by the physiological structure to create a reflected ultrasound signal, the first transducer generates a first received signal from the reflected ultrasound signal, the second transducer generates a second received signal from the reflected ultrasound signal, and the processing device normalizes the first received signal with the second received signal or the second received signal with the first received signal.

摘要: A method of making a disposable ultrasound transducer interface pad includes forming a flexible, impermeable substrate layer having a first side and an opposing second side; applying a first hydrophilic material to the first side of the impermeable substrate layer to form a first hydrophilic layer, wherein the first hydrophilic material is configured to be activatable to provide an acoustic coupling between a patient and an ultrasound transducer; and curing the first hydrophilic layer to form a continuous first hydrophilic layer on the first surface of the impermeable substrate layer.

摘要: Internal bleeding systems, devices, and methods are disclosed that include a sensing module and a processing module. The sensing module has an ultrasound module and a communication module. The ultrasound module emits and receives ultrasound energy to and reflected from tissue in a patient and generates a reflected energy signal. The communication module transmits the reflected energy signal to the processing module. The processing module analyzes the reflected energy signal to determine if it indicates the presence of blood from internal bleeding in the patient.

摘要: Aspects of the technology described herein related to controlling, using control circuitry, modulation circuitry to modulate and delay first ultrasound data generated by first ultrasound transducers positioned at a first azimuthal position of an ultrasound transducer array of an ultrasound device and second ultrasound data generated by second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array of the ultrasound device, such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount. The first and second ultrasound data received from the modulation circuitry may be filtered and summed. The ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry may be integrated onto a semiconductor chip or one or more semiconductor chips packaged together.

摘要: The embodiments herein provide a system for calibration-free cuff-less evaluation of blood pressure. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers are configured to measure the change in arterial dimensions, pulse wave velocity, and other character traits of an arterial segment over continuous cardiac cycle, which is then used to evaluate blood pressure parameters without any calibration procedure using dedicated mathematical models. The pressure sensor/force sensor/bio-potential transducers/accelerometric sensors are configured to measure a pressure acting on a skin surface at a measurement site, an internal arterial transmural pressure level, an applied pressure or a hold-down pressure on the skin surface or an arterial site, biopotential and/or plethysmograph signal, arterial vibrations acting on the measurement site as a function of the arterial pressure and the mechanical characteristics and/or a function of the applied/hold-down pressure and/or function of external factors.

摘要: A system for monitoring blood flow in a patient, the system comprising: a single-element disc-shaped ultrasound transducer for fastening to the patient and a controller subsystem. The controller subsystem is configured to: control the ultrasound transducer to transmit a series of plane-wave pulses into the patient in a propagation direction; sample reflections of the plane-wave pulses, received at the ultrasound transducer, from a region within the patient, to generate pulse-Doppler response signals; and process the pulse-Doppler response signals to calculate a blood flow curve for waveform analysis.
