example 1

[0218] A system for measuring blood pressure may include a test device 1400 , a peripheral device 240 and a server 120 . Figure 14-A An exemplary test setup according to some embodiments of this embodiment is shown. The test device 1400 may include an information acquisition module 1410, an analysis module 220', a display module 1420 and a memory device 1470. According to this embodiment, the information obtaining module 1410 is adapted to obtain information, such as one or a combination of ECG signals, PPG signals and the like. The analysis module 220' is adapted to analyze the acquired information, or determine or estimate a physiological parameter (e.g., a physiological parameter of interest), or both. The display module 1420 is adapted to display at least some of the acquired information, one or a combination of physiological parameters and the like. The memory device 1470 is adapted to store one or a combination of detected or acquired signals, physiological param...

[0240] Referring again to Example 1, a system for measuring blood pressure is shown in Figure 14-A to Figure 14-C. SBP and DBP can be estimated by a calibration model based on the identified PTT and calibration data including PTTO, SBPO, DBPO, PTTV0 and HRV0. The coefficients of the calibration function may be determined by a calibration process. In some embodiments, a set of calibration data about the subject may be acquired and stored in a memory device or server 120 . A set of calibration data may include one or a combination of PTTO, SBPO, DBPO, PTTV0, HRV0 and the like. A set of calibration data can be obtained by a healthcare professional located in a hospital or doctor's office, by the subject himself or by a lay assistant. A set of calibration data can be acquired using a clinical device or a home device. A set of calibration data can be obtained based on a previous measurement using the system. One or more sets of calibration data may be used to determine the co...

[0243] Figure 15-A to Figure 15-D Some examples of raw data for two subjects (Subject 1 and Subject 2) measured under different conditions and fitted curves with different functions, different models, or both. Figure 15-A (a) shows the measured raw SBP-PTT data for Subject 1 (indicated by the diamonds connected by dashed lines), the data fitted with a cubic polynomial function (indicated by the solid curve). Figure 15-A (b) shows the measured raw DBP-PTT data for Subject 1 (indicated by the diamonds connected by dashed lines), the data fitted with a quartic polynomial function (indicated by the solid curve). Figure 15-B (a) shows the measured raw SBP-PTT data for Subject 2 (indicated by the diamonds connected by dashed lines), the data fitted with a polynomial function of degree seven (indicated by the solid curve). Figure 15-B (b) shows the measured raw DBP-PTT data for Subject 2 (indicated by the diamonds connected by dashed lines), the data fitted with an octagonal po...

Abstract

A device (110), method and system (100) for calculating, estimating, or monitoring the blood pressure of a subject are disclosed. At least one processor, when executing instructions, may perform one or more of the following operations. A first signal representing heart activity of the subject may be received. A second signal representing time-varying information on at least one pulse wave of the subject may be received. A first feature in the first signal may be identified. A second feature in the second signal may be identified. A pulse transit time based on a difference between the first feature and the second feature may be computed. The blood pressure of the subject may be calculated according to a first model based on the computed pulse transit time and a first set of calibration values, the first set of calibration values relating to the subject.

Description

[0001] cross reference [0002] This application claims priority from Chinese Patent Application No. 201520188152.9 filed on March 31, 2015, the contents of which are incorporated herein by reference. technical field [0003] The present disclosure generally relates to a system and method applicable to healthcare related fields. In particular, the present disclosure relates to a system and method for blood pressure monitoring. Background technique [0004] Traditional blood pressure measurement systems, also known as sphygmomanometers, use Korotkoff sounds or the oscillometric method to determine blood pressure based on the relationship between external pressure and arterial volume pulse size. This traditional blood pressure measurement system involves the use of an inflatable armband to restrict blood flow. Various cuff-based methods work discontinuously, with several minutes or more between successive measurements. Currently, professional societies recommend the use of ...
