PORTABLE BLOOD PRESSURE MEASURING DEVICE
The portable blood pressure measuring device includes a body part in which a controller for calculating blood pressure information, a display for outputting blood pressure information, and a power supply are built; a wrist strap coupled to the body part; a fastening unit for fastening the wrist strap to the wrist; a first pressure sensor coupled to a first position of the wrist strap; and a second pressure sensor coupled to a second position of the wrist strap, in which the first pressure sensor is disposed to be adjacent to a position under which the user's radial artery passes, and the second pressure sensor is disposed to be adjacent to a position under which the user's ulnar artery passes, in which the controller calculates a blood pressure based on a first pressure, a second pressure and an interference constant determined by the wrist strap.
System and method for evaluating blood flow in a vessel
A system for evaluating blood flow in a vessel of a patient includes a catheter containing a first pressure sensor and a second pressure sensor and configured to simultaneously measure pressure data within a vessel on either side of a stenosis. Pressure data generated by the catheter includes a first series of pressure measurements from the first pressure sensor a second series of pressure measurements from the second pressure sensor. The system further includes an FFR calculation module executable on one or more processors and configured to calculate a stability index for each of two or more portions of the pressure data, wherein each stability index indicates at least one of heart rate stability and catheter stability for the respective portion of the pressure data. An optimal time window is identified based on the stability indexes for calculation of fractional flow reserve (FFR) based on the pressure data. An FFR value is then calculated based on the pressure data in the optimal time window.
HEART RATE MEASUREMENTS USING HEARING DEVICE AND APP
A method for monitoring placement of a first physiologic sensor of a hearing device with respect to an ear of a user, the first physiologic sensor configured to monitor a heart rate of the user of the hearing device, includes: obtaining first physiologic sensor data from the first physiologic sensor at the hearing device; obtaining second physiologic sensor data from a second physiologic sensor at an external device, the second physiologic sensor configured to detect the heart rate of the user; performing a comparison based on the first physiologic sensor data from the first physiologic sensor, and the second physiologic sensor data from the second physiologic sensor; and setting a reference physiologic sensor data based on the first physiologic sensor data and/or the second physiologic sensor data if the comparison results in a match, or providing a notification if the comparison does not result in a match.
AUTOMATED FIELD OF VIEW ALIGNMENT FOR MAGNETIC RESONANCE IMAGING
Disclosed herein is a medical system (100, 300, 500) comprising a memory (110) storing machine executable instructions (120) and a predictor algorithm (122) configured for outputting predicted field of view alignment data (128) for a magnetic resonance imaging system (502) in response to inputting one or more localizer magnetic resonance images (124) and subject metadata (126). The predictor algorithm comprises a trainable machine learning algorithm. The medical system further comprises a processor (104) configured for controlling the medical system. Execution of the machine executable instructions causes the processor to: receive (200) the one or more localizer magnetic resonance images and the subject metadata; and receive (202) the predicted field of view alignment data from the predictor algorithm in response to inputting the one or more localizer magnetic resonance images into the predictor algorithm and in response to inputting the subject metadata.
APPARATUS AND METHOD FOR NON-CONTACT MEASURING MOMENTUM BY USING IR-UWB RADAR
The present invention can provide an apparatus and a method for non-contact measuring momentum, the apparatus and the method being capable of quantitatively measuring the dynamic activity and static activity of a subject by using a plurality of IR-UWB radars and, particularly, capable of measuring, in real time, some activities of the human body and general activity of the human body by distinguishing moving activity of the subject from non-moving activity. Therefore, the activity of a subject is non-contact measured so as to minimize user inconvenience, thereby facilitating performance of an ADHD test even for a subject in a young age group, and thus ADHD can be diagnosed early.
INFORMATION PROCESSING DEVICE, STATE DETERMINATION SYSTEM, ENERGY CALCULATION SYSTEM, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM
Provided is an information processing device including an acquisition unit configured to acquire motion information of a foot of a user measured by a motion measurement device and a determination unit configured to determine whether or not the user is in a pedaling state in which the user pedals a bicycle based on an angle between a sole and a ground generated from the motion information.
His bundle and bundle branch pacing adjustment
The present disclosure relates generally to pacing of cardiac tissue, and more particularly to adjusting delivery of His bundle or bundle branch pacing in a cardiac pacing system to achieve synchronized ventricular activation. Bundle pacing may be delivered in response to determining whether the QRS parameter or activation interval is greater than a threshold. A set of AV delays may be generated, and an optimal AV delay may be selected from the stored set of AV delays. His-bundle or bundle-branch pacing may be selectively delivered based on RV or LV activation time. Pacing may also be adjusted based on dyssynchrony detected or the type of bundle branch block pattern detected.
Heart signal waveform processing system and method
A computer-implemented method, computer program product and computing system for receiving a single-lead heartbeat waveform for a user; associating a heart health indicator with the single-lead heartbeat waveform; and providing the heart health indicator to a recipient.
Optical Device for Determining Pulse Rate
Some embodiments provide a wearable monitoring device including a motion sensor and a photo (PPG) sensor. The PPG sensor includes (i) a periodic light source, (ii) a photo detector, and (iii) circuitry determining a user's heart rate from an output of the photo detector. Some embodiments provide methods for operating a heart rate monitor of a wearable monitoring device to measure one or more characteristics of a heartbeat waveform. Some embodiments provide methods for operating the wearable monitoring device in a low power state when the device determines that the device is not worn by a user.
INTEGRATED SYSTEM FOR ASSESSING WOUND EXUDATES
An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.
