Description
本发明涉及医疗设备技术领域，特别涉及一种超声系统数据的选段方法、存储介质及超声设备。The present invention relates to the field of medical device technologies, and in particular, to a method for selecting ultrasound system data, a storage medium, and an ultrasound device.
脑血流自动调节机能(以下简称“血流调节机能”)，是指当平均动脉压(MABP)在一定范围内波动时，通过小动脉和毛细血管平滑肌的代偿性扩张或收缩，改变脑血管阻力(CVR)，使脑血流(CBF)保持相对恒的生理机能。血流调节机能可通过CBF＝MABP/CVR表示，对于正常人，当平均动脉压在50mmHg-170mmHg范围内波动时，血流调节机能使MABP与CVR成正比变化，从而保证CBF维持相对恒定。而对于卒中患者，由于动脉粥样硬化使血管的舒缩功能障碍，血流调节机能的上下限都高于正常人，所以能耐受高血压，但不能耐受低血压。此时若使用药物导致血压低于血流调节机能范围下限，CBF随MABP被动下降，可造成灶区脑组织梗死面积增大及神经功能恶化，情况严重时甚至导致患者死亡。解决这一问题的关键在于对血流调节机能的准确测量。因此，及时、准确的评价患者的血流调节机能，对于脑血管疾病的诊断及治疗有重要的指导意义。The cerebral blood flow autoregulation function (hereinafter referred to as "blood flow regulation function") refers to the change of the brain through the compensatory expansion or contraction of small arteries and capillary smooth muscles when the mean arterial pressure (MABP) fluctuates within a certain range. Vascular resistance (CVR) keeps cerebral blood flow (CBF) relatively constant physiological function. The blood flow regulation function can be expressed by CBF=MABP/CVR. For normal people, when the mean arterial pressure fluctuates within the range of 50mmHg-170mmHg, the blood flow regulator can make the MABP and CVR change in proportion, thus ensuring that the CBF remains relatively constant. For stroke patients, because atherosclerosis causes vasomotor dysfunction, the upper and lower limits of blood flow regulation function are higher than normal, so they can tolerate high blood pressure, but can not tolerate hypotension. At this time, if the blood pressure is lower than the lower limit of the blood flow regulation function, the CBF passively decreases with the MABP, which may cause an increase in the infarct area and neurological function of the brain tissue in the focal area, and even lead to death in a serious situation. The key to solving this problem is the accurate measurement of blood flow regulation. Therefore, timely and accurate evaluation of the patient's blood flow regulation function has important guiding significance for the diagnosis and treatment of cerebrovascular diseases.
传统的方法是通过超声系统采集脑血流数据及连续血压数据，并将采集得到的脑血流数据及连续血压数据保存为离线文件。再通过用户手动选择需要的数据段，并进行离线分析，以得到脑电流自动调节指数，增加了获取脑电流自动调节指数的操作过程，给用户的使用带来不变。The traditional method is to collect cerebral blood flow data and continuous blood pressure data through an ultrasound system, and save the collected cerebral blood flow data and continuous blood pressure data as an offline file. Then, the user manually selects the required data segment and performs offline analysis to obtain the brain current automatic adjustment index, which increases the operation process of acquiring the brain current automatic adjustment index, and brings the user's use unchanged.

在所述步骤S200中，所述预设选段条件为预先设置，用于判断采集的脑血流数据和连续血压数据是否可以进行选段。所述预设选段条件包括采集脑血流数据和连续血压数据的采样时长和/脑血流数据和连续血压数据的有效性。In the step S200, the preset selection condition is preset to determine whether the collected cerebral blood flow data and the continuous blood pressure data can be selected. The preset selection condition includes the sampling duration of the cerebral blood flow data and the continuous blood pressure data and/or the validity of the cerebral blood flow data and the continuous blood pressure data.
在本发明的一个实施例中，所述判断所述脑血流数据及连续血压数据是否满足预设选段条件具体包括:In an embodiment of the present invention, the determining whether the cerebral blood flow data and the continuous blood pressure data meet the preset selection condition specifically includes:
S201、获取所述脑血流数据及连续血压数据的采样时长，并将所述采样时长与预设时长阈值进行比较；S201: Obtain a sampling duration of the cerebral blood flow data and the continuous blood pressure data, and compare the sampling duration with a preset duration threshold;
S202、当所述采样时长大于预设时长阈值时，判定所述脑血流数据及连续血压数据满足预设选段条件。S202. When the sampling duration is greater than a preset duration threshold, determining that the cerebral blood flow data and the continuous blood pressure data satisfy a preset selection condition.
具体地，所述采样时长指的是获取采样时长的当前时刻至开始采集脑血流数据及连续血压数据的开始时刻的时间间隔。所述获取所述脑血流数据及连续血压数据的采样时长具体为分别获取当前采样数据对应的当前采样时间以及采集的第一个采样数据的最初采样时间，根据所述当前采样时间及最初采样时间计算采样时长。在实际应用中，由于脑血流数据和连续血压数据的采样点同步，从而可以仅获取脑血流数据/连续血压数据的采样时长，并将所述采样时间与预设时间阈值进行比较，这样可以减少预设选段条件判断的操作步骤，提高数据选段的效率。Specifically, the sampling duration refers to a time interval from a current time at which the sampling duration is acquired to a start time at which the cerebral blood flow data and the continuous blood pressure data are started to be collected. The sampling duration for acquiring the cerebral blood flow data and the continuous blood pressure data is specifically acquiring a current sampling time corresponding to the current sampling data and an initial sampling time of the first sampling data collected, according to the current sampling time and the initial sampling. Time calculates the sampling duration. In practical applications, since the sampling points of the cerebral blood flow data and the continuous blood pressure data are synchronized, only the sampling duration of the cerebral blood flow data/continuous blood pressure data can be acquired, and the sampling time is compared with the preset time threshold, so that It can reduce the operation steps of the preset selection condition judgment and improve the efficiency of data selection.

The amount of data is compared with the preset amount of data. When the amount of data is greater than the preset amount of data, it is determined that it meets the preset selection condition.
