传统的中医诊脉，在通过把脉获取脉象信息的同时，把“一息之间脉几至”作为脉搏波搏动快慢的诊断标准，有“一息四到五至，三至则迟，六至则数”之说。其中“一息”即为一呼一吸。可见，呼吸波的采集对中医脉象诊断具有重要的临床意义。但目前的脉搏波诊断系统，一般只是通过传感器采集脉搏波，根据脉搏波的幅值与时值特征，提取时域或频域特征参数进行分析研究，并没有包含呼吸波信息。这样的脉诊系统不能重现传统脉诊“一息几至”的脉诊依据，不利于对脉象的准确诊断，在一定程度上阻碍了对脉搏波全面深入的研究。The traditional Chinese medicine diagnosis pulse, while obtaining the pulse information through the pulse, uses the pulse between the breath and the pulse as the diagnostic criteria for the pulse wave pulsation. There are "four to five to three, three to late, six to the number". Said. One of them is a breath. It can be seen that the collection of respiratory waves has important clinical significance for the diagnosis of pulse of traditional Chinese medicine. However, the current pulse wave diagnosis system generally only collects pulse waves through sensors, and extracts time domain or frequency domain characteristic parameters according to the amplitude and time characteristics of the pulse wave, and does not include respiratory wave information. Such a pulse diagnosis system can not reproduce the pulse diagnosis basis of the traditional pulse diagnosis, which is not conducive to the accurate diagnosis of the pulse, and to a certain extent hinders the comprehensive and in-depth study of the pulse wave.

所述发明的一种兼具呼吸波采集的脉搏波诊断系统第一个方面使用脉搏波传感器采集待测人员脉搏波，是在一定时间内，利用脉搏波传感器在人体外周某一区域单个位置进行脉搏波采集，或利用阵列式脉搏波传感器在人体外周某一区域的多个位置进行脉搏波同步采集。The first aspect of the invention relates to a pulse wave diagnosis system with respiratory wave acquisition. The pulse wave sensor is used to collect the pulse wave of the person to be tested, and the pulse wave sensor is used to perform a single position in a certain area of the human body outside the body within a certain period of time.

测量获取呼吸波的传感器进行呼吸波同步采集，及其他方式进行呼吸波同步采集；另一种情况是使用同步呼吸波信号提取器处理脉搏波传感器采集的脉搏波数据，提取脉搏波信号中的呼吸波信号，实现呼吸波信号的获取。The second aspect of the pulse wave diagnosis system with respiratory wave acquisition of the present invention uses a respiratory wave acquisition device to acquire a synchronized respiratory wave of a person to be tested. One case is that the pulse wave sensor performs pulse wave acquisition while using a non-contact type. Synchronous acquisition of respiratory waves by sensors such as Pule radar or respiratory chest straps that acquire respiratory waves based on thoracic displacement, or chest impedance based on impedance method
The sensor that acquires the respiratory wave is used for synchronous acquisition of the respiratory wave, and the other method is used for synchronous acquisition of the respiratory wave; the other is to use the synchronous respiratory wave signal extractor to process the pulse wave data collected by the pulse wave sensor, and extract the breathing in the pulse wave signal. The wave signal realizes the acquisition of the respiratory wave signal.

For example, the synchronous pulse wave and the respiratory wave signal collected in S102 are processed by filtering and denoising, and the time domain and frequency domain characteristic parameters of the pulse wave and the respiratory wave are extracted by using algorithms such as Fourier transform and EMD.
在步骤S104中得出“一息几至”等脉搏波及呼吸波交互关系。例如图3根据本发明的一个实施例的兼具呼吸波采集的脉搏波诊断系统所
获得的脉搏波及呼吸波交互关系波形图，如图3所示，S201是脉搏波波形，S202是与脉搏波同步的呼吸波波形；根据在S103中的脉搏波数据处理结果，选取脉搏波数据稳定的时间区间T1；根据S103中同步呼吸波数据处理的结果，选取呼吸波数据稳定的时间区间T2；T3为脉搏波稳定时间T1与呼吸波稳定时间T2的时间重合部分；进一步对数据进行处理，得T3时间区间内脉搏跳动次数N1，与T3时间区间内呼吸次数N2；则可得一息之间脉搏波至数为N1/N2。除一息之间至数信息外，也可得出呼吸波与脉搏波的其他相互关系。In step S104, a pulse wave and a respiratory wave interaction relationship such as "a few moments" are obtained. For example, FIG. 3 is a waveform diagram of a pulse wave and a respiratory wave interaction relationship obtained by a pulse wave diagnosis system having respiratory wave acquisition according to an embodiment of the present invention. As shown in FIG. 3, S201 is a pulse wave waveform, and S202 is a pulse wave.

In addition to the information between the breaks, other correlations between the respiratory wave and the pulse wave can be derived.
在步骤S105中根据所有数据得出脉搏波诊断信息。例如：综合S101中记录的待测人员个人信息及采集日期时间等信息，及S103中脉搏波和呼吸波的数据处理结果，及S104中获得的一息之间脉搏波至数信息，以传统中医脉诊理论为依据，得出脉象诊断结果。Pulse wave diagnosis information is derived from all the data in step S105. For example, the information of the personal information of the person to be tested and the date and time of collection recorded in S101, and the data processing results of the pulse wave and the respiratory wave in S103, and the pulse wave number information between the information obtained in S104, in the traditional Chinese medicine pulse Based on the diagnosis theory, the pulse diagnosis results are obtained.
图4是本发明的兼具呼吸波采集的脉搏波诊断系统的另一实施例的流程图。4 is a flow chart of another embodiment of a pulse wave diagnostic system having respiratory wave acquisition of the present invention.
在步骤S301中登记待测人员个人信息及采集日期时间等信息。例如：登记待测人员年龄、身高、体重、病史等个人信息，以及登记进行采集脉搏波及呼吸波时的日期时间等。这是由于脉搏波的形态特征会随待测人员年龄、季节、时辰等因素变化，记录待测人员的个人信息以及采集时间日期等信息，有利于得出准确的脉搏波诊断结果。In step S301, information such as personal information of the person to be tested and date and time of collection are registered. For example, register the personal information such as the age, height, weight, and medical history of the person to be tested, and register the date and time when collecting the pulse wave and the respiratory wave. This is because the morphological characteristics of the pulse wave will change with the age, season, and time of the person to be tested. Recording the personal information of the person to be tested and the time and date of the acquisition will help to obtain accurate pulse wave diagnosis results.
在步骤S302中采集待测人员脉搏波。例如：使用由压力传感器构成的多路阵列式脉搏波传感器，在人体体表某一区域进行无创多点脉搏波同步采集，存储脉搏波数据。The pulse wave of the person to be tested is collected in step S302. For example, a multi-channel array pulse wave sensor composed of a pressure sensor is used to perform non-invasive multi-point pulse wave synchronous acquisition in a certain region of the human body surface, and store pulse wave data.
在步骤S303中对脉搏波进行数据处理并提取呼吸波。例如：对S302中采集的脉搏波进行去噪等处理，使用傅里叶变换、EMD等算法，从脉搏波中提取呼吸波。在此基础上，对脉搏波和提取出的呼吸波进一步进行处理，获取脉搏波和呼吸波的时域和频域特征参数。The pulse wave is subjected to data processing and a respiratory wave is extracted in step S303. For example, the pulse wave collected in S302 is denoised and processed, and a respiratory wave is extracted from the pulse wave using an algorithm such as Fourier transform or EMD. On this basis, the pulse wave and the extracted respiratory wave are further processed to acquire the time domain and frequency domain characteristic parameters of the pulse wave and the respiratory wave.
在步骤S304中得出“一息几至”等脉搏波及呼吸波交互关系。例如：如图3所示，S201为采集的脉搏波波形，S202为对脉搏波进行数据处理后，从脉搏波中提取的呼吸波波形；根据在S303中的脉搏波数
据处理结果，选取脉搏波数据稳定的时间区间T1；根据S303中从脉搏波提取出的呼吸波数据处理的结果，选取呼吸波数据稳定，波形良好的时间区间T2；T3为脉搏波稳定时间T1与呼吸波稳定时间T2的时间重合部分；进一步对数据进行处理，得T3时间区间内脉搏跳动次数N1，与T3时间区间内呼吸次数N2；则可得一息之间脉搏波至数为N1/N2。除一息之间至数信息外，也可得出其他呼吸波与脉搏波相互关系。In step S304, a pulse wave and a respiratory wave interaction relationship such as "a few moments" are obtained. For example, as shown in FIG. 3, S201 is the acquired pulse wave waveform, S202 is a respiratory wave waveform extracted from the pulse wave after data processing on the pulse wave, and pulse wave is selected according to the pulse wave data processing result in S303. The time interval T 1 of data stabilization; according to the result of the processing of the respiratory wave data extracted from the pulse wave in S303, the time interval T 2 in which the respiratory wave data is stable and the waveform is good is selected; T 3 is the pulse wave stabilization time T 1 and the respiratory wave stabilization time period T 2 overlapping portions; data further processed to obtain the time interval T the pulse beats. 3 N 1, and the time interval T the number of breaths. 3 N 2; information can be obtained between the pulse wave to a number of N 1 / N 2 . In addition to the information between the breaks, other respiratory waves and pulse waves can be derived.
在步骤S305中根据所有数据得出脉搏波诊断信息。例如：综合S301中记录的待测人员个人信息及采集日期时间等信息，及S303中脉搏波和呼吸波的数据处理结果，及S304中获得的一息之间脉搏波至数信息，以传统中医脉诊理论为依据，得出脉象诊断结果。Pulse wave diagnosis information is derived from all the data in step S305. For example, the information of the personal information of the person to be tested recorded in S301 and the date and time of collection, and the data processing results of the pulse wave and the respiratory wave in S303, and the pulse wave number information between the information obtained in S304, in the traditional Chinese medicine pulse Based on the diagnosis theory, the pulse diagnosis results are obtained.
至此，已全面说明了本发明的兼具呼吸波采集的脉搏波诊断系统及使用其进行诊断的方法。该系统通过呼吸波信息的引入，最大可能的还原了传统诊脉方式，获取了更为全面的生理信息作为脉搏波诊断依据，不仅为脉搏波准确诊断提供了可能，也为脉搏波的深入研究提供了新的思路。Heretofore, the pulse wave diagnosis system having the respiratory wave acquisition of the present invention and a method of using the same for diagnosis have been fully described.
