In addition, the sensor cartridge of certain embodiments of the disclosure can be configured to allow a single sensor to comfortably accommodate treatment sites of various sizes such as for both adult and pediatric applications. | 2022-07-14 |
20220218285 | Toothbrush Having Physiological Sensing Function - A toothbrush having a physiological sensing function, comprising a grip part, a head part, and a sensing module. The grip part has an inner space as well as a top end and a tail end opposite to each other in a length direction. The head part is provided at the top end of the grip part. The grip part is further provided with a sensing region. The sensing module is provided in the inner space of the grip part and disposed corresponding to the sensing region. The sensing module executes a physiological sensing function in the sensing region, and generates physiological sensing information. When a user holds the toothbrush to brush teeth, a finger pulp or palm of the user presses on the sensing region, and thus the sensing module can execute the physiological sensing function by means of the sensing region and generate physiological sensing information, so that the user can understand his/her own health information more comprehensively. | 2022-07-14 |
20220218286 | Apparatus, System and Method for Medical Analyses of Seated Individual - Apparatus, system and method for medical analysis of a seated individual, includes determining the aortic valve opening; the PTT; and calculating the PWV. Determining the aortic valve opening includes collecting BCG data while sitting on a seat and determining the timing of the aortic valve opening, taking into account posture. Measuring the aortic pulse wave transit time includes collecting BCG data while sitting on a seat capable of measuring changes in apparent weight; determining the timing of the aortic valve opening; detecting the arrival of the pulse wave at the end point; and measuring the relative timings of the two events. Calculating the PWV includes determining a length of the arterial segment through which a pulse wave is to be measured between a start point and an end point; and dividing the determined length of the arterial segment by the PTT. | 2022-07-14 |
20220218287 | DISEASE-CONDITION ASSESSMENT DEVICE, DISEASE-CONDITION ASSESSMENT METHOD, PROGRAM FOR DISEASE-CONDITION ASSESSMENT DEVICE, AND DISEASE-CONDITION ASSESSMENT SYSTEM - Provided are a disease-condition assessment device for assessing a disease condition of a subject, a disease-condition assessment method, a program for disease-condition assessment device, and a disease-condition assessment system. The disease condition assessment device acquires a data of a seat pressure distribution on a seating surface where a subject operating a vehicle is seated, calculates a center position depending on the seat pressure distribution, calculates a degree of laterality in the seat pressure distribution based on the center position, and assesses a disease condition of the subject depending on the degree of laterality. | 2022-07-14 |
20220218288 | SIGNAL ADJUSTMENT METHOD FOR PPG APPARATUS AND PPG APPARATUS - Provided are a signal adjustment method for a PPG apparatus and a PPG apparatus. The method comprises: when background light data or actual effective light data does not meet a preset background light data range or a preset first effective light data range, performing a dimming operation comprising: determining an estimated current transfer ratio; estimating a driving current required by a light source and a gain required by an analog front end; calculating estimated effective light data of a PPG apparatus according to the estimated driving current required by the light source, the gain required by the analog front end, and the estimated current transfer ratio; when the estimated effective light data meets a preset second effective light data range, generating a to-be-adjusted current/gain value according to the estimated driving current required by the light source and the gain required by the analog front end. | 2022-07-14 |
20220218289 | PREDICTING TRANSIENT ISCHEMIC EVENTS USING ECG DATA - Apparatuses and methods are provided to predict or diagnose an ischemic event, such as a stroke or a transient ischemic attack (TIA). A machine-learning model such as a neural network is generated that allows for recognition of an ECG consistent with an ischemic event. A system is trained and used to process a recording of ECG data from a patient to generate a prediction indicating a likelihood that the patient will experience a stroke. In other examples, a system is trained and used to process a recording of ECG data from a patient and detect an ischemic event for the patient who did not appear to have such an ischemic event. | 2022-07-14 |
20220218290 | SYSTEMS AND METHODS CONFIGURED TO PROVIDE ASTHMA-RELATED INFORMATION OF SUBJECTS BASED ON ENVIRONMENTAL CONDITIONS AND/OR SUBJECT CONDITION INFORMATION - Systems and methods configured to provide asthma-related information of subjects based on environmental conditions and/or subject condition information are disclosed. Exemplary implementations may: obtain location information related to a physical location of a subject over time; obtain, based on the location information, environmental conditions at or around the physical location indicated by the location information; obtain subject condition information defining remote diagnostic information and subject health information; and effectuate presentation of a graphical user interface that conveys the subject condition information. | 2022-07-14 |
20220218291 | OPTICAL PATIENT MONITOR - An optical based patient monitoring system employing an optical sensor and providing an indication of an optical change which does not correlate to a change in a physiological blood parameter and based on that indication, providing a care provider an indication of a condition of a patient. The optical based patient monitoring system providing the indication of the patient condition in relation to a patient using an IV setup. | 2022-07-14 |
