Description

Technical Field

[0001] The invention relates to the field of medical technology, and in particular to a method and system for evaluating the cerebral blood flow autoregulation function based on upright tilting. Background Art

[0002] The upright tilt test and transcranial doppler (TCD) cerebral blood flow monitoring are commonly used neurophysiological techniques to evaluate the functional status of the heart and brain, but they also have their own shortcomings. The simple upright tilt test mainly evaluates the patient's cardiovascular response to changes in body position, but there is a lack of real-time monitoring of cerebral blood flow velocity during the test, and it is impossible to evaluate the functional status of the brain. TCD cerebral blood flow monitoring examinations are usually performed with the patient lying flat or sitting still, and it is impossible to evaluate the dynamic cerebral blood flow velocity in an upright or tilted state, making it difficult to fully evaluate the functional status of the brain.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1 As shown, the first aspect of the present invention discloses a method for evaluating the cerebral blood flow autoregulation function based on upright tilt, comprising the following steps: S102: attaching a number of electrocardiogram electrodes to the chest of the target individual to record the electrical activity of the heart; and installing two transcranial doppler cerebral blood flow monitoring probes on the brain of the target individual by means of a head frame to record the cerebral blood flow velocity; S104: adjusting the connection status of the electrocardiogram, blood pressure and cerebral blood flow monitoring probes, and adjusting the waveform status of the electrocardiogram waveform and the cerebral blood flow monitoring waveform, until the connection status of the electrocardiogram and cerebral blood flow monitoring probes and the waveform status of the electrocardiogram waveform meet the requirements; S106: Check and calibrate the cerebral blood flow monitoring probe to ensure that interference is reduced; S108: After the functional state of the cerebral blood flow monitoring probe is set, the preset stimulation task is performed on the target individual; at this time, the cerebral blood flow monitoring instrument records the speed of the cerebral blood flow and generates a corresponding waveform diagram; S110: adjusting the upright tilting platform to a horizontal position, and starting the first stage of data collection; synchronously starting the cerebral blood flow monitoring device and the cerebral blood flow monitoring probe, and starting to collect the cerebral blood flow, blood pressure and electrocardiogram data of the target individual in a horizontal position; S112: collecting stable data of the first preset collection time as baseline data; adjusting the upright tilt platform to a preset tilt angle, and starting the second stage of data collection; S114: In the tilted position, continue to synchronously collect the target individual's electrocardiogram, blood pressure, and cerebral blood flow data within a second preset collection time; S116: returning to the supine position, and collecting ECG data, blood pressure, and cerebral blood flow data for the third preset collection time; S118: Assessing the cerebral blood flow autoregulation ability of the target individual according to the electrocardiogram data and the cerebral blood flow data.

[0022] The hardware of this product mainly consists of an upright tilting bed, a matching computer and software system, TCD wires, amplifiers, display units and a host. The specific process and technical details are as follows: Multiple electrodes are attached to the patient's chest to record the heart's electrical activity (12 leads). Based on the patient's head shape, electrodes are attached to monitor cerebral blood flow, and the electrodes are arranged according to the international standard 10-20 system to ensure good contact between the electrodes and the scalp; Check the connection between the ECG and cerebral blood flow monitoring electrodes, and check whether the ECG waveform is good; perform impedance check and calibration on the cerebral blood flow monitoring electrodes to ensure impedance balance between electrodes and reduce interference and noise. Once the cerebral blood flow monitoring electrodes are placed, the patient is asked to remain still, close or open their eyes, and perform specific tasks or stimulations as needed. The cerebral blood flow monitoring instrument will record the cerebral blood flow velocity and generate a corresponding waveform graph; Adjust the upright tilt platform to a horizontal position to start the first phase of data collection; Synchronously start the ECG monitoring device and the cerebral blood flow monitoring electrodes to start collecting the cerebral blood flow and ECG signals of the patient in a horizontal position; Collect stable data for a certain period of time (e.g. 10 minutes) as baseline data; The upright tilt platform was slowly adjusted to the preset tilt of 70° to start the second phase of data collection; In the tilted position, continue to synchronously collect the patient's ECG and cerebral blood flow signals for a certain period of time (such as 20 minutes). If the patient syncs or has presyncope, terminate the examination at any time; The patient returned to the supine position and collected ECG and cerebral blood flow data for 10 minutes; Analyze key electrocardiogram (waveform, heart rate, rhythm, T wave and QRS wave, etc.), blood pressure and cerebral blood flow monitoring parameters (such as spectrum, amplitude, rhythm and waveform characteristics) to quantitatively evaluate brain function.

[0023] According to the inspection requirements, multiple tilt angles can be set, and even nitroglycerin drug-induced tests can be performed to collect cerebral blood flow monitoring data under different conditions. The recorded cerebral blood flow data will be filtered, amplified, and converted to analog for subsequent analysis and interpretation.

[0024] The collected raw data, processed characteristic parameters, and evaluation results are stored and managed to establish the patient's brain function profile. It supports the review and comparison of historical data, making it convenient for doctors to conduct longitudinal analysis and follow-up evaluation.

[0025] It should be noted that by simultaneously acquiring cerebral blood flow velocity information in real time, a more comprehensive brain function assessment result can be provided. The upright tilt platform can change different body positions to test brain function status under different conditions, thereby improving the diversity and effectiveness of the examination. This method is expected to promote the development of syncope diagnosis and brain function assessment, and provide new tools and methods for scientific research. This technology can be applied to the diagnosis and assessment of cerebrovascular diseases, neurodegenerative diseases and other fields in medical institutions and scientific research institutions to improve the accuracy and comprehensiveness of diagnosis.

[0031] Furthermore, in a preferred embodiment of the present invention, the collected raw data, processed data and evaluation result information are stored and managed to establish a brain function profile of the target individual.

[0032] It should be noted that the head-up tilt test and cerebral blood flow velocity are two important indicators for evaluating brain function, but traditional examination methods usually perform them separately and cannot obtain both types of information at the same time. Figure 2 As shown, this method combines the upright tilt test with the cerebral blood flow monitoring examination, which can provide a more comprehensive and real-time understanding of the brain function status. This method based on the upright tilt platform combined with the cerebral blood flow monitoring examination can realize the synchronous collection and real-time recording of the patient's cerebral blood flow velocity data under different states, providing more comprehensive, objective and quantitative data support for the evaluation of cardiocerebral function, and assisting clinical diagnosis and treatment decision-making.
