技术领域technical field

本发明涉及一种传感器定位技术领域，特别涉及一种动脉定位器技术领域。The invention relates to the technical field of sensor positioning, in particular to the technical field of an artery locator.

背景技术Background technique

在进行重大手术和部分重症监护时，需对病人进行动脉穿刺置管以监测血流动力学指标，如平均动脉压、收缩压、舒张压等等。因此，准确判断动脉的位置是动脉穿刺成功的关键，现有的方法为人眼观察和人工触摸，即凭穿刺人员的经验进行穿刺，然而人的视觉和触觉误差较大，穿动脉时，常常找不到最佳穿刺点而造成穿刺失败，增加病人的痛苦，延误治疗进度，并且动脉的走势并非直线，选择最合适的位置进行穿刺才能保证整个动脉穿刺针正确的置留在动脉中，所以利用传感器来精确定位动脉位置将是代替人工的最佳方法，现有技术中并没有相关的医疗器械出现。During major operations and some intensive care, arterial catheterization is required to monitor hemodynamic indicators, such as mean arterial pressure, systolic blood pressure, diastolic blood pressure, etc. Therefore, accurately judging the position of the artery is the key to successful arterial puncture. The existing methods are human eye observation and manual touch, that is, the puncture is performed based on the experience of the puncturer. However, human visual and tactile errors are relatively large. Failure to reach the optimal puncture point will cause puncture failure, increase the pain of the patient, delay the progress of the treatment, and the trend of the artery is not a straight line. Only by selecting the most suitable position for puncture can the entire artery puncture needle be placed correctly in the artery, so use Accurately locating the position of the artery with a sensor will be the best method to replace manual work, and there is no related medical device in the prior art.

为解决上述技术问题，本发明提供一种动脉定位器，通过传感器来精确定位动脉位置，并且可以确定动脉走势，提高动脉穿刺的成功率。In order to solve the above technical problems, the present invention provides an artery locator, which accurately locates the position of the artery through a sensor, and can determine the trend of the artery to improve the success rate of artery puncture.

本发明是通过以下的技术方案实现的：The present invention is achieved through the following technical solutions:

一种动脉定位显示器，包括：与动脉接触，感受动脉跳动所产生压力的压力分布测量装置、显示动脉强度值和动脉走势的显示器以及连接所述压力分布测量装置和显示器的连接线。An arterial location display, comprising: a pressure distribution measuring device that is in contact with an artery to sense the pressure generated by the beating of the artery, a display that displays arterial strength values and arterial trends, and a connecting line connecting the pressure distribution measurement device and the display.

所述压力分布测量装置是传感器，在与动脉接触一侧的外边缘设置刻度。The pressure distribution measuring device is a sensor, and a scale is set on the outer edge of the side in contact with the artery.

所述显示器所显示的内容为动脉跳动所产生的压力最强点的刻度值和在所述传感器感受范围内的动脉走势图像。The content displayed on the display is the scale value of the strongest point of pressure generated by the beating of the artery and the image of the trend of the artery within the sensing range of the sensor.

本发明的有益效果为：利用传感器代替人工判断来确定动脉位置，确定的位置精确，并且由于采用电子设备方法将动脉定位方法器械化，可以显示动脉走势，提高动脉穿刺的成功率。The beneficial effect of the present invention is: the position of the artery is determined by using the sensor instead of manual judgment, and the determined position is accurate, and because the arterial positioning method is instrumentalized by using the electronic device method, the trend of the artery can be displayed, and the success rate of arterial puncture can be improved.

具体实施方式Detailed ways

以下结合附图，对本发明作进一步说明。Below in conjunction with accompanying drawing, the present invention will be further described.

如图1，是动脉定位器的示意图，包括：与动脉接触，感受动脉跳动所产生压力的压力分布测量装置1、显示动脉强度值和动脉走势的显示器2以及连接所述压力分布测量装置1和显示器2的连接线3，其中压力分布测量装置1是传感器，传感器优选为压电陶瓷传感器、压电薄膜传感器、压电式压力传感器、压力分布型传感器、超声波传感器和激光传感器中的一种，但不限于上述传感器，任何灵敏度能达到感受动脉跳动的传感器均可以被使用，在显示器2上面可以显示动脉跳动所产生的压力最强点的刻度值7和在所述压力分布测量装置1测量范围内的动脉走势图像8。As shown in Figure 1, it is a schematic diagram of an artery locator, including: a pressure distribution measurement device 1 that contacts the artery to feel the pressure generated by the beating of the artery, a display 2 that displays arterial strength values and arterial trends, and connects the pressure distribution measurement device 1 and The connecting wire 3 of the display 2, wherein the pressure distribution measuring device 1 is a sensor, and the sensor is preferably one of a piezoelectric ceramic sensor, a piezoelectric film sensor, a piezoelectric pressure sensor, a pressure distribution sensor, an ultrasonic sensor and a laser sensor, But not limited to the above-mentioned sensors, any sensor whose sensitivity can reach the feeling of arterial beating can be used, and the scale value 7 of the strongest pressure point generated by the arterial beating can be displayed on the display 2 and the measurement range of the pressure distribution measuring device 1 Inside the arterial trend image 8.

如图2，是压力分布测量装置的放大图，可以看到在压力分布测量装置1与动脉接触的一侧的外边缘设置刻度4，刻度4为等分刻度，可以根据具体情况设计不同的量程。As shown in Figure 2, it is an enlarged view of the pressure distribution measuring device. It can be seen that a scale 4 is set on the outer edge of the side where the pressure distribution measuring device 1 is in contact with the artery. The scale 4 is an equal scale, and different ranges can be designed according to specific conditions .

如图3，是压力分布测量装置上刻度的放大图，可以清晰可见等分刻度4。As shown in Figure 3, it is an enlarged view of the scale on the pressure distribution measuring device, and the equal division scale 4 can be clearly seen.

如图4，是动脉定位器的等效代替方式图，包括显示器2，连接线3和压力分布测量装置1，压力分布测量装置1为传感器。As shown in Fig. 4, it is an equivalent replacement diagram of an artery locator, including a display 2, a connecting line 3 and a pressure distribution measuring device 1, and the pressure distribution measuring device 1 is a sensor.

从上述附图可以看出，本发明的工作原理为：压力分布测量装置1为传感器，可以分布在与动脉接触的整个接触面，其与动脉接触并感受动脉跳动所产生的压力，并转换成电信号输出，然后经过前置运算放大器5将采集的信号进行放大，再通过A/D转换芯片6将放大的模拟信号转换成数字信号，再交给单片机上的主控制程序处理，然后在显示器2上面显示动脉跳动所产生的压力最强点的刻度值7和在所述压力分布测量装置1测量范围内的动脉走势图像8，即由于压力分布测量装置1与动脉接触的接触面全部为传感器，在传感器上可以感受到由动脉跳动所产生的压力，整个接触面范围内的动脉走势情况亦可以完整地反应在显示器2上面，并以图像形式输出。As can be seen from the above drawings, the working principle of the present invention is: the pressure distribution measuring device 1 is a sensor, which can be distributed on the entire contact surface in contact with the artery, which contacts the artery and feels the pressure generated by the beating of the artery, and converts it into The electrical signal is output, and then the collected signal is amplified through the pre-operational amplifier 5, and then the amplified analog signal is converted into a digital signal through the A/D conversion chip 6, and then handed over to the main control program on the microcontroller for processing, and then displayed on the display 2. The above shows the scale value 7 of the strongest pressure point generated by the beating of the artery and the trend image 8 of the artery within the measurement range of the pressure distribution measuring device 1, that is, because the contact surfaces of the pressure distribution measuring device 1 and the artery are all sensors , the pressure generated by the beating of the artery can be felt on the sensor, and the trend of the artery within the entire contact surface range can also be completely reflected on the display 2 and output in the form of an image.

如图5，是动脉定位器工作原理的结构框图，压力分布测量装置1，即传感器与动脉接触，感受由动脉跳动所产生的压力，由于压力分布并不均匀，有强点和弱点的不同，所以传感器感受到的压力信号也不同，通过运算放大器5的处理，再通过A/D转换模块6将模拟信号转化为数字信号，并通过单片机控制芯片9输入控制程序，在显示器2上面显示由传感器感受的动脉跳动最强点的刻度值7和传感器与动脉接触范围内的动脉走势图像8的情况，由于与动脉接触的压力分布测量装置1上面设置刻度，可根据显示器2上面显示的刻度对应相应的位置进行动脉穿刺，提高动脉穿刺的成功率。As shown in Figure 5, it is a structural block diagram of the working principle of the artery locator. The pressure distribution measuring device 1, that is, the sensor is in contact with the artery to feel the pressure generated by the beating of the artery. Since the pressure distribution is not uniform, there are differences in strengths and weaknesses. So the pressure signal felt by the sensor is also different. Through the processing of the operational amplifier 5, the analog signal is converted into a digital signal by the A/D conversion module 6, and the control program is input by the single-chip microcomputer control chip 9, and the pressure signal generated by the sensor is displayed on the display 2. In the case of the scale value 7 of the strongest point of arterial beating felt and the arterial trend image 8 within the range of contact between the sensor and the artery, since the pressure distribution measuring device 1 in contact with the artery is provided with a scale, it can correspond to the scale displayed on the display 2 Arterial puncture at the correct position to improve the success rate of arterial puncture.
