Description
Technical Field
The invention relates to the technical field of intelligent terminals, in particular to an output method of a cerebral blood flow automatic regulation index, a storage medium and ultrasonic equipment.
Background
The cerebral blood flow autoregulatory function (hereinafter, referred to as "blood flow regulatory function") is a physiological function that changes Cerebral Vascular Resistance (CVR) by compensatory expansion or contraction of small arteries and capillary smooth muscles when mean arterial pressure (MABP) fluctuates within a certain range, so that Cerebral Blood Flow (CBF) is kept relatively constant. The flow regulation function can be expressed by CBF = MABP/CVR, which for normal persons, when the mean arterial pressure fluctuates in the range of 50mmHg-170mmHg, the flow regulation function changes MABP in direct proportion to CVR, thus ensuring that CBF remains relatively constant. In the case of stroke patients, atherosclerosis causes dysfunction of the vasomotor function and the upper and lower limits of the blood flow regulation function are higher than those of normal persons, so that patients can tolerate hypertension but cannot tolerate hypotension. At this time, if the blood pressure is lower than the lower limit of the blood flow regulation function range due to the use of the medicine, the CBF is passively reduced along with the MABP, so that the infarct area of the brain tissue in the focal zone is increased, the nerve function is deteriorated, and even the death of the patient is caused in serious conditions. The key to solving this problem is the accurate measurement of the flow regulation function. Therefore, the blood flow regulation function of the patient can be evaluated timely and accurately, and the method has important guiding significance for the diagnosis and treatment of the cerebrovascular diseases.
The traditional method is to collect cerebral blood flow data and continuous blood pressure data through an ultrasonic system, and store the collected cerebral blood flow data and continuous blood pressure data as an off-line file. The user analyzes the off-line file to obtain the cerebral blood flow automatic adjustment index, so that on one hand, the operation process of obtaining the cerebral blood flow automatic adjustment index is increased, on the other hand, real-time dynamic analysis cannot be performed in an ultrasonic transcranial Doppler system, and synchronous analysis is performed on multi-channel cerebral blood flow data and continuous blood pressure data, which brings inconvenience to the user.

Referring to fig. 1, fig. 1 is a flowchart illustrating an output method of an index for automatically adjusting cerebral blood flow according to a preferred embodiment of the present invention. The method comprises the following steps:
s100, collecting multi-channel cerebral blood flow data and continuous blood pressure data, wherein sampling points of all channels are synchronous;
s200, respectively selecting cerebral blood flow data and continuous blood pressure data of each channel according to a preset data volume to obtain a sampling data section of each channel;
s300, synchronously analyzing the sample data section of each channel, and displaying the analysis result of each channel on a display interface according to groups.
The embodiment provides an output method of an automatic cerebral blood flow regulation index, which dynamically selects a sample data section in real time from acquired multi-channel cerebral blood flow data and continuous blood pressure data, synchronously analyzes the cerebral blood flow data and the continuous blood pressure data of each channel to synchronously obtain the cerebral blood flow regulation index of the cerebral blood flow data and the continuous blood pressure data of each channel, and displays the cerebral blood flow regulation indexes on a display interface according to groups, thereby realizing the purpose of synchronously presenting a plurality of groups of automatic cerebral blood flow regulation indexes in an ultrasonic transcranial Doppler system in real time and bringing convenience to users.
Specifically, in the step S100, the multi-channel cerebral blood flow data and continuous blood pressure data may be acquired by an ultrasound system, that is, the ultrasound system respectively acquires cerebral blood flow data and continuous blood pressure data of each channel, and sampling points of the cerebral blood flow data and the continuous blood pressure of each channel are synchronous. That is, the cerebral blood flow data of each channel and the continuous blood pressure data have the same sampling time, so that the characteristic information of the patient, which is reflected by the cerebral blood flow data and the continuous blood pressure data, at the same time can be ensured. In this implementation, the cerebral blood flow data and the continuous blood pressure data are both acquired by ultrasound transcranial Doppler (TCD-TranHcraial Doppler).
Furthermore, the multichannel cerebral blood flow data and the continuous blood pressure data can be synchronously displayed on a display interface in real time while being collected, and the section selection and the analysis of the cerebral blood flow automatic regulation index are performed while being displayed on the display interface, so that the cerebral blood flow data and the continuous blood pressure data can be visually displayed, and the cerebral blood flow automatic regulation index can be synchronously analyzed and displayed.
In the step S200, respectively selecting the cerebral blood flow data and the continuous blood pressure data of each channel according to the preset data amount means that the cerebral blood flow data and the continuous blood pressure data of each channel are respectively and automatically selected according to a preset rule. The preset rule is a rule for automatically selecting cerebral blood flow data and continuous blood pressure data. In this embodiment, the preset rule is to select the data of the latest acquired preset data amount as the sampling data segment.
Further, the automatic selection refers to selecting cerebral blood flow data and continuous blood pressure data of a preset data volume at intervals of preset time to generate various sample data sections. The preset data amount may be set by default in the system, and may be set by the user, for example, the data amount collected for 3 minutes. Correspondingly, the cerebral blood flow data and the continuous blood pressure data with the preset data volume automatically selected at the preset time interval can be selected once at 5 seconds intervals, and the data volume of 3 minutes is selected each time.
In an embodiment of the present invention, the automatically selecting the sampling data segment of the cerebral blood flow data and the continuous blood pressure data according to the preset rule specifically includes:
h11, determining the current cerebral blood flow data and the continuous blood pressure number acquired at the current moment;
h12, selecting a sampling data segment with a preset data volume according to a preset rule by taking the current cerebral blood flow data and the continuous blood pressure data as initial positions.
Specifically, the current time refers to a time for executing the selection operation, and the current time is used as an initial time, and current cerebral blood flow data and continuous blood pressure data corresponding to the current time are obtained. That is to say, the sample data segment is the data corresponding to the selection time as the starting point, so that the newest of the acquired selected data segment is ensured, and the data segment is dynamically acquired.
Further, the automatically selecting the sampling data segment of the preset data volume according to the preset rule by taking the current cerebral blood flow data and the continuous blood pressure data as initial positions specifically comprises:
h121, taking the current cerebral blood flow data and the continuous blood pressure data as initial positions, and selecting sampling data with a preset data size away from the initial positions as end positions according to the sequence of sampling time;
h122, selecting forebrain blood flow data and continuous blood pressure data between the starting position and the ending position to obtain a sample data section of the brain blood flow data and the continuous blood pressure data.
Specifically, the ending position is determined according to the sequence of the sampling time corresponding to the acquired data, so that the timeliness of the data segment can be ensured.
In an embodiment of the present invention, in order to facilitate the subsequent determination of the time corresponding to each data segment, a sampling time corresponding to the start position of the data segment and a sampling time corresponding to the end position of the data segment may be added to the data segment to mark the data segment. Correspondingly, after selecting the forebrain blood flow data and the continuous blood pressure data between the starting position and the ending position to obtain a sample data section of the forebrain blood flow data and the continuous blood pressure data, the method further comprises the following steps: and acquiring a first sampling moment corresponding to the starting position and a second sampling moment corresponding to the ending position, and marking the first sampling moment and the second sampling moment in the sample selection data segment.
In an embodiment of the present invention, in order to ensure the reliability of the selected data segment, before the cerebral blood flow data and the continuous blood pressure data are selected according to the preset data amount, determining whether the multichannel cerebral blood flow data and the continuous blood pressure data satisfy a preset segment selection condition may be further included. The preset section selection condition is preset and is used for judging whether the collected cerebral blood flow data and continuous blood pressure data can be subjected to section selection. The preset section selection condition comprises the sampling time of collecting cerebral blood flow data and continuous blood pressure data and/or the effectiveness of the cerebral blood flow data and the continuous blood pressure data.
For example, the determining whether the multi-channel cerebral blood flow data and continuous blood pressure data satisfy the preset selection condition specifically includes:
h21, acquiring the sampling duration of the cerebral blood flow data and the continuous blood pressure data, and comparing the sampling duration with a preset duration threshold;
h22, when the sampling duration is larger than a preset duration threshold, judging that the cerebral blood flow data and the continuous blood pressure data meet a preset section selection condition.
Specifically, the sampling duration refers to a time interval from a current time when the sampling duration is acquired to a start time when the cerebral blood flow data and the continuous blood pressure data start to be acquired. The sampling duration for acquiring the cerebral blood flow data and the continuous blood pressure data is specifically to acquire current sampling time corresponding to the current sampling data and initial sampling time of first acquired sampling data respectively, and calculate the sampling duration according to the current sampling time and the initial sampling time. In practical application, because the sampling points of the cerebral blood flow data and the continuous blood pressure data are synchronous, the sampling duration of the cerebral blood flow data/the continuous blood pressure data can be obtained only, and the sampling time is compared with a preset time threshold, so that the operation steps of judging the preset section selection condition can be reduced, and the efficiency of data section selection is improved.
The preset time length threshold is preset, and the preset time length threshold can be determined according to preset data quantity so as to ensure that the data quantity acquired in the preset time length threshold is more than the preset data quantity and to ensure that a sampling data section containing the preset data quantity can be selected. In addition, when judging whether the preset section selection condition is met, the data volume can be directly adopted for comparison, that is, when the cerebral blood flow data and the continuous blood pressure data are collected, the data volume of the collected cerebral blood flow data/continuous blood pressure data is recorded in real time, the collected data volume is compared with the preset data volume, and when the data volume is more than the preset data volume, the preset section selection condition is judged to be met. It should be noted that, when the cerebral blood flow data is multi-channel cerebral blood flow data, it is sufficient to determine the cerebral blood flow data of only one channel.
Further, when the sampling duration is less than or equal to a preset duration threshold, the cerebral blood flow data and the continuous blood pressure data are continuously acquired, and preset section selection conditions are repeatedly judged on the acquired data.
In another embodiment of the present invention, when the sampling duration is greater than a preset duration threshold, the determining that the cerebral blood flow data and the continuous blood pressure data satisfy a preset selection condition specifically includes:
h21a, detecting the validity of the collected cerebral blood flow data and continuous blood pressure data, wherein the validity comprises validity and invalidity;
h22a, if the validity is valid, judging that the cerebral blood flow data and the continuous blood pressure data meet the preset section selection condition.
In this embodiment, the preset selection condition is validity of the cerebral blood flow data and the continuous blood pressure data. The validity refers to whether the cerebral blood flow data and the continuous blood pressure data are within a preset range or not so as to ensure the correctness of the cerebral blood flow data and the continuous blood pressure time. The preset range is preset, and the cerebral blood flow data and the continuous blood pressure data correspond to different preset ranges respectively so as to ensure various correctness.
Further, when the validity is invalid, judging that the cerebral blood flow data and the continuous blood pressure data do not meet the preset section selection condition, and prompting a user that data collection is wrong. In practical application, the reminding of the acquisition error can be displayed on a display interface, and the reminding can also be realized through sound.
In another embodiment of the present invention, when the sampling duration is greater than a preset duration threshold, the determining that the cerebral blood flow data and the continuous blood pressure data satisfy a preset selection condition specifically includes:
h21b, acquiring the sampling duration of the cerebral blood flow data and the continuous blood pressure data, and comparing the sampling duration with a preset duration threshold;
h22b, when the sampling duration is larger than a preset duration threshold, detecting the validity of the cerebral blood flow data and the continuous blood pressure data;
h23b, if the validity is valid, judging that the cerebral blood flow data and the continuous blood pressure data meet the preset section selection condition.
In this embodiment, through double judgment of sampling duration and validity, it is ensured that a selected data segment with a preset data size is selected, and reliability of data in the selected data segment is improved.
Further, in the step H300, the synchronizing the analysis of the sample data segments of the channels refers to analyzing the sample data segments of the channels respectively, and the analysis is performed synchronously, so that the cerebral blood flow autoregulation indexes of the channels can be obtained simultaneously. The display according to groups refers to that the cerebral blood flow data and the continuous blood pressure data of each channel corresponding to the same section time are used as a group, the cerebral blood flow automatic regulation indexes corresponding to the cerebral blood flow data of each channel in the group are used as a group of automatic regulation indexes, and the reorganized automatic regulation indexes are displayed on a display interface.
Furthermore, because the cerebral blood flow data of each channel correspond to different cerebral blood vessel parameters, when the cerebral blood flow data and the continuous blood pressure data of each channel are analyzed, the cerebral blood vessel parameters corresponding to each channel can be obtained, and the corresponding cerebral blood flow automatic regulation index can be obtained according to the analysis of the cerebral blood vessel parameters.
For example, the analyzing the sample data section of each channel synchronously and displaying the analysis result of each channel on the display interface according to a group specifically includes:
s301, obtaining blood vessel parameters corresponding to the sampling data of each channel, and analyzing the corresponding sampling data according to the blood vessel parameters to obtain a cerebral blood flow automatic regulation index;
and S302, synchronously displaying the cerebral blood flow automatic regulation indexes on a display interface according to groups.
Specifically, the blood vessel parameter is obtained when brain blood flow data is acquired, can be obtained through an ultrasonic transcranial doppler device, and is stored in an ultrasonic transcranial doppler system, so that the blood vessel parameter can be used when a brain blood flow automatic regulation index is acquired.
Further, the synchronous analysis of the sample data section of each channel may specifically be performed by using a TFA transfer function method to analyze the sample data section of each channel, so as to obtain a corresponding cerebral blood flow automatic adjustment index.
