一种脉搏信号检测方法及血压测量装置Pulse signal detecting method and blood pressure measuring device 技术领域Technical field
本发明属于医疗器械技术领域,具体的是涉及一种检测动脉血液脉搏信号的方法及使用该方法的血压测量装置,尤其是一种通过两个可充气气囊在一肢体部位血流的上下游同时检测压力和脉搏信号的方法和以此方法为基础的血压测量装置。The invention belongs to the technical field of medical instruments, and particularly relates to a method for detecting an arterial blood pulse signal and a blood pressure measuring device using the same, in particular to a bloodstream of two limbs at the same time. A method of detecting a pressure and a pulse signal and a blood pressure measuring device based on the method.
背景技术Background technique
血压测量最常用的方法之一是采用一种具有一个可充气气囊的袖带,通过加压先将人体肢体动脉血流阻断,然后缓慢减压,在减压过程中,通过检测血流通过阻断区时所产生的柯氏音,或者是动脉压力在袖带中所产生的脉搏波信号强弱变化值等信息,确定动脉血液的收缩压和舒张压。专利号CN201010247968.6,标题为“一种无创血压测量装置及其测量方法”的专利文献介绍了一种使用脉搏波探头检测袖带下游动脉脉动信号,从而确定收缩压和舒张压的血压计。这种脉搏波探头通过压力感应器或者是光电感应器检测袖带下游动脉脉动信号,专利号为CN201220159276.0,标题为“一种双气囊绑带”的专利文献介绍了一种双体联接式双气囊袖套,所述袖带有上游气囊绑带体与下游气囊绑带体,且所述上游气囊绑带体与所述下游气囊绑带体按照动脉血流方向间距为30cm以内固定连接。所述下游气囊绑带体用于检测受测肢体下游血液流动脉冲,并以此确定受测肢体动脉血液的压力。One of the most common methods of blood pressure measurement is to use a cuff with an inflatable balloon that first blocks the blood flow of the body's limb arteries and then slowly decompresses it. During the decompression process, blood flow is detected. The Korotkoff sound generated when the zone is blocked, or the change in the intensity of the pulse wave signal generated by the arterial pressure in the cuff, determines the systolic blood pressure and diastolic blood pressure of the arterial blood. Patent No. CN201010247968.6, entitled "A Non-Invasive Blood Pressure Measurement Device and Measurement Method Therefor", describes a sphygmomanometer that uses a pulse wave probe to detect pulsation signals downstream of the cuff to determine systolic and diastolic blood pressure. The pulse wave probe detects the pulsation signal of the downstream artery of the cuff through a pressure sensor or a photoelectric sensor. The patent number is CN201220159276.0, and the patent document entitled "A double airbag strap" introduces a double body coupling type. The double airbag sleeve has an upstream airbag strap body and a downstream airbag strap body, and the upstream airbag strap body and the downstream airbag strap body are fixedly connected within 30 cm according to an arterial blood flow direction. The downstream airbag strap is used to detect a blood flow pulse downstream of the tested limb and thereby determine the pressure of the arterial blood of the limb being tested.
现有技术尚未解决上下游气囊绑带应该按何种方式加压以及加压到何种压力程度,才能最有效地在上下游气囊绑带中检测到可用于测量受测肢体血压的血流脉冲,从而准确、可靠地测量血压的问题。The prior art has not solved the manner in which the upstream and downstream airbag straps are pressurized and pressurized to what extent, in order to most effectively detect blood flow pulses that can be used to measure the blood pressure of the measured limb in the upstream and downstream airbag straps. To accurately and reliably measure the blood pressure problem.
发明内容Summary of the invention
为了解决上述问题,本发明提供了一种准确、可靠的血压计,特别是提供一种对一肢体上绑扎的两个可充气气囊进行充气加压,以便有效地检测其中的脉搏信号的方法,以及使用该方法准确测量血压计的装置。In order to solve the above problems, the present invention provides an accurate and reliable sphygmomanometer, and more particularly to a method for inflating and pressurizing two inflatable airbags ligated on a limb to effectively detect a pulse signal therein. And a device for accurately measuring the sphygmomanometer using the method.
为了达到上述目的,本发明是通过以下技术方案实现的:In order to achieve the above object, the present invention is achieved by the following technical solutions:
本发明一种血压测量装置,测量装置用于通过被测者肢体部位测量动脉血 压,测量装置包括The invention provides a blood pressure measuring device for measuring arterial blood through a limb part of a test subject Pressure, measuring device includes
两个充气气囊上游气囊和下游气囊;上游气囊与下游气囊在同一袖带内或在两个相连接的不同袖带内或在两个不相连接的不同袖带内,袖带用于绑定在一被测肢体上;Two inflatable airbag upstream and downstream airbags; the upstream airbag and the downstream airbag are in the same cuff or in two connected different cuffs or in two different cuffs that are not connected, the cuff is used for binding On a limb being tested;
两个与上游气囊与和游气囊中的一个或两个分别或同时连接的压力传感器第一压力传感器和第二压力传感器;Two pressure sensors, a first pressure sensor and a second pressure sensor, respectively connected to one or both of the upstream air bag and the air bag;
一个微处理器,微处理器执行包括以下步骤的血压测量过程:A microprocessor that performs a blood pressure measurement process that includes the following steps:
A)将下游气囊加压到被测动脉收缩压和舒张压之间的一个压力值,或者被测动脉的平均血压值减10mmHg和平均血压值加20mmHg之间的一个压力值,或者一个压力值,使在此压力值时在下游气囊中检测到的脉搏信号幅度大于一给定值;A) pressurizing the downstream balloon to a pressure value between the measured arterial systolic pressure and diastolic pressure, or a pressure value between the mean blood pressure value of the measured artery minus 10 mmHg and the average blood pressure value plus 20 mmHg, or a pressure value So that the amplitude of the pulse signal detected in the downstream airbag at this pressure value is greater than a given value;
B)将上游气囊加压到高于被测动脉收缩压的一个压力值;B) pressurizing the upstream balloon to a pressure value above the systolic blood pressure of the artery to be tested;
C)对上游气囊缓慢泄气,在上游气囊缓慢泄气过程中,通过第一压力传感器测量上游气囊中不断变化的气压,并通过第二压力传感器同时测量下游气囊中的脉搏信号,根据脉搏信号和上游气囊中的气压,或所述脉搏信号和所述上游气囊中的气压之间的关系,确定被测动脉收缩压或舒张压。C) Slowly deflation of the upstream airbag, during the slow deflation of the upstream airbag, the changing air pressure in the upstream airbag is measured by the first pressure sensor, and the pulse signal in the downstream airbag is simultaneously measured by the second pressure sensor, according to the pulse signal and the upstream The air pressure in the balloon, or the relationship between the pulse signal and the air pressure in the upstream balloon, determines the measured systolic or diastolic blood pressure.
本发明的进一步改进在于:在步骤A)中,将下游气囊加压到被测动脉的收缩压和舒张压之间的一个压力值和将下游气囊加压到被测动脉的平均血压值减10mmHg和平均血压值加20mmHg之间的一个压力值的方法是均是在对下游气囊加压的过程中,实时检测下游气囊中气压信号所携带的脉搏信号,当脉搏信号幅度由零增加到最大,然后开始下降时,停止加压;和将下游气囊加压到一个压力值,以使在此压力值时在下游气囊中检测到的脉搏信号幅度大于一给定值的方法是,将在对下游气囊加压的过程中,实时检测下游气囊中气压信号所携带的脉搏信号,当脉搏信号幅度由零增加到大于给定值时,停止加压;A further improvement of the present invention resides in that in step A), the downstream balloon is pressurized to a pressure value between the systolic pressure and the diastolic pressure of the artery to be tested and the average blood pressure value of the downstream balloon is pressurized to the artery to be measured minus 10 mmHg. And a method of adding a pressure value between the average blood pressure value and 20 mmHg is to detect the pulse signal carried by the air pressure signal in the downstream airbag in real time during the process of pressurizing the downstream airbag, and when the amplitude of the pulse signal increases from zero to the maximum, Then, when the descent begins, the pressurization is stopped; and the downstream air bag is pressurized to a pressure value such that the amplitude of the pulse signal detected in the downstream air bag at the pressure value is greater than a given value, which will be downstream During the process of airbag pressurization, the pulse signal carried by the air pressure signal in the downstream airbag is detected in real time, and when the amplitude of the pulse signal increases from zero to a given value, the pressurization is stopped;
在步骤A)中,脉搏信号幅度给定值为1.3mmHg到1.8mmHg之间的一个值,最好为1.5mmHg。In step A), the pulse signal amplitude is given a value between 1.3 mmHg and 1.8 mmHg, preferably 1.5 mmHg.
在步骤B)中,将上游气囊加压到高于被测动脉收缩压的一个压力值的方法是,在对上游气囊加压的过程中,实时监测下游气囊中的脉搏信号幅度的变化,当下游气囊中的脉搏信号幅度随上游气囊的气压的增加从大变小,最后消失时, 停止加压。In step B), the method of pressurizing the upstream balloon to a pressure value higher than the measured systolic blood pressure is to monitor the change of the amplitude of the pulse signal in the downstream airbag in real time during the pressurization of the upstream balloon. The amplitude of the pulse signal in the downstream airbag changes from large to small as the air pressure of the upstream airbag increases, and finally disappears. Stop the pressurization.
本发明的进一步改进在于:将下游气囊加压到一个压力值,使在此压力值时在下游气囊中检测到的脉搏信号幅度大于一给定值的方法是,对下游气囊分段加压,并在每一段加压结束后,检测下游气囊中的脉搏信号,当脉搏信号幅度大于给定值时,停止加压,对下游气囊分段加压的分段目标为:80mmHg,120mmHg,160mmHg,200mmHg。A further improvement of the present invention is that the downstream airbag is pressurized to a pressure value such that the amplitude of the pulse signal detected in the downstream airbag at the pressure value is greater than a given value by compressing the downstream airbag segment. And after each end of the pressurization, the pulse signal in the downstream airbag is detected. When the amplitude of the pulse signal is greater than a given value, the pressurization is stopped, and the segmentation targets for the downstream airbag segment are: 80 mmHg, 120 mmHg, 160 mmHg, 200mmHg.
