Example Embodiment

[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] A heart sound and pulse wave transit time measurement method, collecting and measuring heart sounds and pulse signals, and calculating the pulse wave transit time based on the heart sounds and pulse measurement results; among them,

[0052] Heart sound measurement includes the following steps:

[0053] Step 1: Pick up the heart sound, place an electret sensor in the stethoscope catheter, use the stethoscope to collect the heart sound signal of the user's aortic valve area, the heart sound signal is preprocessed, analog-to-digital converted into a digital signal, and the digital signal is transmitted through the Bluetooth module Sound processing module to smart phone;

[0054] Step two, heart sound envelope extraction, the sound processing module extracts the envelope of the heart sound signal through Hilbit tr...

Abstract

The invention discloses a measuring method for heart sound and pulse wave transmission time and a portable measuring device. A heart sound and pulse signal is acquired and measured. A pulse wave transmission time is calculated through the heart sound and a pulse measuring result. Heart sound measurement comprises heart sound picking, heart sound envelope extracting and heart sound characteristic point positioning. Pulse measurement comprises pulse signal acquiring and pulse signal characteristic point positioning. The method and the device are used for measuring the heart sound and the pulse wave transmission time and can realize real-time measurement for the heart sound and the pulse wave transmission time. Contacting between electrodes with relatively low experience and the skin for acquiring an ECG signal is not required. Measurement can be realized by means of existing intelligent mobile terminal equipment. The method and the device have advantages of high comfort and high portability.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for measuring heart sound and pulse wave transit time and a portable measuring device. Background technique [0002] At present, the indirect auscultation method (mercury sphygmomanometer) is widely used to measure blood pressure clinically. This method needs to be inflated and deflated by the cuff. The measurement time is relatively long, the operation is troublesome and the comfort is poor. In addition, this method relies on listening to determine blood pressure. It is easily affected by the subjective factors of the measurer; on the basis of listening, a related electronic blood pressure measurement system has been developed combined with electronic measurement technology. However, this type of system and method cannot achieve real-time and continuous measurement through inflation and deflation. In addition, the user experience of the inflation and deflation process i...
