20210298710 | X-RAY CT DEVICE - An X-ray CT device includes: an X-ray source that irradiates an object to be imaged with an X-ray; an X-ray detector that is disposed on one side opposite to the X-ray source with a position, at which the object to be imaged is to be disposed, interposed therebetween and detects the X-ray having passed through the object to be imaged; and a rotary unit that supports the X-ray source and the X-ray detector and rotates the X-ray source and the X-ray detector together around the object to be imaged. A distance between the X-ray source and a predetermined reference position positioned in the object to be imaged is variable, and a distance between the reference position and the X-ray detector is variable. | 2021-09-30 |
20210298711 | AUDIO BIOMARKER FOR VIRTUAL LUNG FUNCTION ASSESSMENT AND AUSCULTATION - A mobile device application prompts and conducts audio and/or video tests using a microphone on a smartphone, tablet or laptop in order to record and analyze a patient's speech, cough, breathing and other sounds in order to diagnose the patient with Covid 19, another ailment, or as having normal ranges not indicative of disease. The mobile device's tests and protocols use program instructions, AI processing and other automated tools to facilitate the speed and reliability of the testing. | 2021-09-30 |
20210298712 | IMAGE-FREE ULTRASOUND FOR NON-INVASIVE ASSESSMENT OF EARLY VASCULAR HEALTH MARKERS - An image-free ultrasound system comprises ultrasound transducers, an ultrasound module, flow restrictors, a pulse detection module, and a measurement module. The ultrasound transducers are positioned at arteries to generate signals based on blood flow and pulse propagation in the arteries. The ultrasound module is in communication with each ultrasound transducer to generate characteristic waves based on the generated signals at the ultrasound transducers. The flow restrictors are positioned at the arteries to restrict blood flow and to generate signals based on the blood flow in the arteries. The pulse detection module is in communication with each flow restrictor to generate pulse waves. The measurement module is in communication with the ultrasound module and the pulse detection module to receive the generated characteristic waves and the pulse waves respectively, where the early vascular health markers are measured by the measurement module based on the characteristic waves and the pulse waves. | 2021-09-30 |
20210298713 | ULTRASOUND PATCH FOR DETECTING FLUID FLOW - An ultrasound patch includes one or more transmit and receive piezoelectric transducer elements. In some embodiments, the transducer elements are positioned on a ramp on a patient pad of the patch that is configured to fit within an anatomic space between the trachea and the sternocleidomastoid muscle to orient the transducer elements toward a carotid artery. In some embodiments, a flexible phased array transducer includes a number of pillar piezoelectric elements joined by a flexible adhesive with metal electrodes deposited thereon. The phased array transducer is mounted to a flexible circuit board that allows the transducer to bend and conform to a subject's anatomy. | 2021-09-30 |
20210298714 | SYSTEM AND METHOD FOR DETERMINING CARDIAC OUTPUT - The invention relates to determining a representation of cardiac output in a patient. Provided are a method and a system for monitoring a cardiac output using a single device inserted into a Central Venous Catheter (CVC) or Peripheral Inserted Central Catheters (PICC) line. In an embodiment, the device contains an elongated body that fits the lumen of a Central Venous Cava or Peripheral Inserted Central Catheters line and has an ultrasound transducer at the tip. By operating the device such that the velocity in both the Superior Vena Cava and Inferior Vena Cava can be sampled continuously the CO is monitored. | 2021-09-30 |
