Embodiment Construction

[0057] The inventor found through investigation that the traditional blood pressure measurement methods mainly include the Korotkoff method and the oscillometric method, both of which require the use of an inflatable cuff to compress the arteries. The user always feels discomfort during the measurement due to the expansion and contraction of the muscles produced by prolonged squeezing, which can cause pain and have an effect on the user's stress level, thereby affecting the measurement result. Furthermore, inflatable cuff-based blood pressure measurement devices generally cannot provide continuous blood pressure measurement information.

[0058] Furthermore, arterial cannulation is an invasive method of continuous blood pressure measurement, which can be used as the "gold standard" for blood pressure measurement. However, this measurement method takes a long time to prepare and requires high requirements for the operator. Complications are likely to occur on the body of the op...

Abstract

An embodiment of the invention relates to the technical field of medical monitoring, in particular to a blood pressure monitoring device, method and system. The device applied to monitoring equipmentcomprises a signal acquiring module, a time delay acquiring module and a blood pressure calculation module and is characterized in that the signal acquiring module is used for acquiring the ballistocardiogram signal, collected by first collecting equipment, of a user and the pulse wave signal, collected by second collecting equipment, of the user, wherein the collecting time of the first collecting equipment is synchronous with the collecting time of the second collecting equipment; the time delay acquiring module uses a peak detection algorithm to calculate the peak time delay of the ballistocardiogram signal and the pulse wave signal according to the ballistocardiogram signal and the pulse wave signal to serve as the pulse wave signal conduction time; the blood pressure calculation module is used for calculating according to the pulse wave signal conduction time to obtain the blood pressure data of the user. By the blood pressure monitoring device, method and system, continuous and real-time blood pressure monitoring can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of medical monitoring, in particular, to a blood pressure monitoring device, method and system. Background technique [0002] As an important physiological parameter of the human body, blood pressure reflects the functional status of the human heart and blood vessels, and has very important guiding significance for diagnosing diseases and observing the effect of treatment. However, the blood pressure of the human body changes with the physiological cycle, personal emotions, various external and internal stimuli, and has obvious fluctuations. Because blood pressure parameters are affected by many factors such as physical condition, environmental conditions, and physiological rhythm, there are large differences in the results of single measurement or intermittent measurement. The continuous blood pressure measurement method can measure the blood pressure value of each cardiac cycle of th...
