Blood pressure regulation and control equipment with closed-loop monitoring based on ear vagus nerve stimulation

Abstract

The invention discloses blood pressure regulation and control equipment with closed-loop monitoring based on ear vagus nerve stimulation. The equipment comprises a dynamic blood pressure monitoring module, an ear vagus nerve stimulator and a feedback regulation and control module; and the feedback regulation and control module is used for controlling the frequency and/or current intensity of the electrical stimulation applied by the ear vagus nerve stimulator according to the blood pressure measurement result of the dynamic blood pressure monitoring module, so that the ratio K of the blood pressure change delta BP to the stimulation parameter A reaches a preset index K<0>, wherein the stimulation parameter A is the product of the stimulation frequency and the current intensity. The blood pressure regulation and control equipment in the invention has the functions of dynamic blood pressure monitoring and feedback regulation and control; personalized blood pressure regulation and controlcan be achieved for individuals; therefore, the treatment effect can be optimized; furthermore, the side effect is controllable; and the blood pressure regulation and control equipment in the invention has the function of finely regulating and controlling the sleep blood pressure, does not influence the morning mental state, can achieve more excellent and stable blood pressure regulation and control within limited treatment time, can effectively regulate the blood pressure trend in the sleep state, and can assist in stable improvement of the blood pressure.

Description

technical field [0001] The invention relates to the technical field of blood regulation, in particular to a blood pressure regulation device including closed-loop monitoring and based on ear vagus nerve stimulation. Background technique [0002] Hypertension is a life-threatening chronic disease, especially for refractory hypertension. Traditional treatments include combined drug methods and surgical nerve damage methods. However, long-term use of drugs has many side effects and is difficult to precisely control; due to the complexity of the brain and nerves and the limitations of human cognition, irreversible surgical damage may produce unpredictable malignant consequences. Acupoint stimulation on the concha of the ear can effectively treat epilepsy, depression, diabetes and hypertension; it is a non-invasive physical therapy method, which is closely related to traditional medicine such as acupuncture and percutaneous vagus nerve stimulation in evidence-based medicine.

AI Technical Summary

Problems solved by technology

However, the current equipment such as the Huatuo brand percutaneous ear vagus nerve stimulator does not contain a monitoring and feedback system, which greatly limits the clinical application of this technology.

Blood pressure regulation based on ear vagus nerve stimulation is carried out by repairing vagus nerve and parasympathetic nerve pathways, and relieves the factors that cause vascular ten...
