Ultramicro implantation type blood pressure measuring and monitoring method and device

Abstract

The invention relates to an ultralow-power-consumption ultra-small-volume in-vivo implantation type blood pressure signal measuring and monitoring method and device. The device is in the form of a capsule. An electromagnetic coupling energy supply system and a rechargeable technology are utilized; a special blood pressure sensing system is utilized to complete blood pressure signal transfer, ultralow-power-consumption signal acquisition and wireless reception and transmission; an in-vitro signal data receiving system completes wireless receiving and conditioning of the signal; and a signal data processing and analyzing system is used for data storage and analysis via an interface module. The invention can monitor the contractive pressure and diastolic pressure in a long-term, safe, stable and direct way in a natural physiological state to acquire mean pressure, pulse rate, blood volume, blood flow and other related parameters, thereby completing display, storage and printing output of blood pressure waveform. The invention is widely used in pharmacological and pathological tests, is effectively used in researching cardiovascular disease, hypertension and diabetes, judging curative effects of related therapeutic drugs, monitoring blood pressure during and after surgeries for diagnosing and treating various diseases, and is applicable to other research fields.

Problems solved by technology

[0002] At present, the Korotkoff sound method used in the known blood pressure measurement has the advantages of methodological error (including auditory error, judgment error, visual lag error, decompression timing error), operational error (including deflation and decompression speed error, banding tightness error, detection error, etc.) The position error of the device, the position error of the person being tested), and the error of the matching equipment (manometer and stethoscope error) and many other errors lead to blood pressure measurement that cannot completely reflect the blood pressure index truly and objectively; the oscillometric electronic sphygmomanometer is unreliable and inaccurate in measuring blood pressure , data discrete; indirect methods of pressure volume method, pressure sensor, and photoelectric sensor cannot truly and objectively measure and monitor blood pressure signals

Direct measurement of blood pressure with implanted blood pressure in the body can truly and effectively obtain blood pressure-related parameters and enable long-term monitoring; domestic research institutions have conducted a lot of research on the construction and functions of implanted systems, but there is still no perfect system solution in terms of size and power consumption Methods and schemes; the existing foreign related technologies are backward, the solutions are not perfect and scientific, and cannot meet the actual application requirements of implantable blood pressure measurement in terms of volume and power consumption
