Non-invasive blood pressure regulation system based on ultrasonic nerve stimulation

Abstract

The invention discloses a non-invasive blood pressure regulation system based on ultrasonic nerve stimulation. The system comprises a blood pressure monitoring device, a central control circuit and anultrasonic stimulation device, wherein the blood pressure monitoring device is used for monitoring, displaying and storing the blood pressure, and sending the monitored blood pressure values to the central control circuit; the central control circuit is used for receiving the blood pressure values sent by the blood pressure monitoring device, switching different ultrasonic nerve stimulation modesaccording to the changing situations of the blood pressure values and outputting control instructions; the ultrasonic stimulation device is used for receiving the control instructions output by the central control circuit and conducting ultrasonic nerve stimulation in different ultrasonic nerve stimulation modes according to the control instructions so as to achieve blood pressure regulation. Theultrasonic stimulation device comprises a random waveform generator, a power amplifier, an impedance matcher, a switching selector, a focused ultrasonic transducer group and a signal feedback device.By means of the non-invasive blood pressure regulation system, while it can be achieved that the blood pressure is monitored in real time, non-invasive blood pressure regulation can be conducted according to a set blood pressure threshold, and the blood pressure is kept to be stable.

Description

technical field [0001] The invention relates to the technical field of ultrasonic regulation, in particular to a non-invasive blood pressure regulation system based on ultrasonic nerve stimulation. Background technique [0002] The stability of people's blood pressure is very important to the health of the human body. Higher or lower than normal blood pressure is called high blood pressure or low blood pressure. Hypertension refers to an increase in systemic arterial blood pressure (systolic blood pressure and / or diastolic blood pressure) as the main feature (systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90 mm Hg), which may be accompanied by heart, brain, kidney and other organ functions Or clinical syndrome of organic damage. Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. If it is not controlled, it is easy to cause lesions in blood vessels and various target organs. Co...

Problems solved by technology

The traditional electrical stimulation method needs to insert electrodes into the stimulation area and requires surgery, which will damage neuron cells during the stimulation process and affect the normal physiological functions of the target

[0006] At present, there are still many deficiencies in the technology of regulating blood pressure through nerve stimulation in the case of real-time monitoring of blood pressure, and it is impossible to monitor blood pressure and regulate voltage through nerve stimulation at the same time.
