SYSTEMS AND METHODS FOR MANAGING A PATIENT
Implementations described and claimed herein provide systems and methods for managing one or more patients. In one implementation, an imaging window is determined based on a location of a probe. A primary image cross-section for the imaging window is identified for the imaging window. At least one image is generated along the primary image cross-section using patient data captured using the probe. The at least one image is compared to an expected image contour scaffold of the primary image cross-section. The probe is commanded to fine-tune an imaging plane based on the comparison until the at least one image matches the expected image contour scaffold of the primary image cross-section.
Rapid pulse confirmation device
A wearable rapid pulse confirmation (RPC) device is designed to be worn by a living subject, and includes a Doppler array comprising at least one piezoelectric ultrasonic transducer, configured to detect a change in blood velocity in a blood vessel; a screen; a loud speaker; and a band or adhesive configured to hold the wearable RPC device in proximity to a body surface of the living subject. The Doppler array is configured to detect a change in blood velocity, pulse rate, pulse strength, or a combination thereof in a blood vessel; and to provide feedback through the screen and the loudspeaker. The Doppler array may include multiple types of piezoelectric ultrasonic transducers, including low frequency piezoelectric ultrasonic transducers having a working frequency ranging from 2 MHz to <6 MHz; medium frequency piezoelectric ultrasonic transducers having a working frequency of 6 MHz to 10 MHz; and high frequency piezoelectric ultrasonic transducers having a working frequency of 10 MHz to 18 MHz.
CONSTITUTIVE EQUATION FOR NON-INVASIVE BLOOD PRESSURE MEASUREMENT SYSTEMS AND METHODS
The disclosed devices, systems and methods measure non-invasive blood pressure in a patient. Energy emissions, such as ultrasound or light, are emitted into tissues of the patient. The emitted energy reflects from various tissues, such as flowing blood and vessels, and can be detected, or received, to generate a reflected energy signal or data. The reflected energy can be processed, such as by using a constitutive equation, to calculate the blood pressure.
BLOOD PRESSURE MEASUREMENT APPARATUS AND METHODS OF USE THEREOF
Provided are an apparatus and method for blood pressure measurement using an electroacoustic transducer in combination with a piezoelectric ultrasonic transducer. The apparatus and method can provide continuous, noninvasive blood pressure monitoring.
Ultrasound device with elevational beamforming
Aspects of the technology described herein relate to apparatuses and methods for performing elevational beamforming of ultrasound data. Elevational beamforming may be implemented by different types of control circuitry. Certain control circuitry may be configured to control memory such that ultrasound data from different elevational channels is summed with stored ultrasound data in the memory that was collected at different times. Certain control circuitry may be configured to control a decimator to decimate ultrasound data from different elevational channels with different phases. Certain control circuitry may be configured to control direct digital synthesis circuitry to add a different phase offset to complex signals generated by the DDS circuitry for multiplying with ultrasound data from different elevational channels.
