摘要：
Provided is an integrated circuit structure for continuous detection of human blood pressure, comprising a photoelectric detection unit (1), a photoplethysmography acquisition circuit (2), a first analog-to-digital conversion circuit (3), an electrocardiographic signal acquisition circuit (4), a second analog-to-digital conversion circuit (5), a digital signal processor (6) and a I2C bus (7), wherein the photoelectric detection unit (1) comprises a light emitting diode (D1) and a photodiode (D2) light generated by the light emitting diode (D1) through transmission or reflection enters the human skin and then is received by the photodiode (D2) and converted into a current signal, a pulse wave signal of the human body is then obtained through the photoplethysmography acquisition circuit (2) meanwhile the electrocardiographic signal acquisition circuit (4) acquires an electrocardiographic signal of the human body the digital signal processor (6) receives the pulse wave signal and the electrocardiographic signal and processes the same to obtain a numerical value representing a continuous blood pressure of the human body, and the value is transmited via the I2C bus (7). The integrated circuit structure can continuously detect the human blood pressure, simplify the measurement process and achieve the miniaturization of the measurement equipment.Linvention concerne une structure de circuit intégré pour la détection continue de la pression artérielle humaine, comprenant une unité de détection photoélectrique (1), un circuit dacquisition de photopléthysmographie (2), un premier circuit de conversion analogique-numérique (3), un circuit dacquisition de signal électrocardiographique (4), un second circuit de conversion analogique-numérique (5), un processeur de signaux numériques (6) et un bus I2C (7), lunité de détection photoélectrique (1) comprenant une diode électroluminescente (D1) et une photodiode (D2) la lumière générée par la diode électroluminescente (D1) par transm
