本实用新型涉及彩超检测技术领域，具体是一种具有压力检测功能的彩超探头。The utility model relates to the technical field of color ultrasound detection, in particular to a color ultrasound probe with a pressure detection function.
背景技术Background Art
彩超通常由探头(相控阵、线阵、凸阵、机械扇扫、三维探头、内窥镜探头等)、超声波发射/接收电路、信号处理和图像显示等部分组成。利用超声多普勒技术和超声回波原理，同时进行采集血流运动、组织运动信息和人体器官组织成像的设备。彩超用于超声成像、测量与血流运动信息采集供临床超声诊断检查使用，探头可经食道、血管内、术中经人体内部组织。Color Doppler ultrasound usually consists of a probe (phased array, linear array, convex array, mechanical fan scanning, three-dimensional probe, endoscope probe, etc.), ultrasonic transmitting/receiving circuit, signal processing and image display. It is a device that uses ultrasonic Doppler technology and ultrasonic echo principle to simultaneously collect blood flow movement, tissue movement information and human organ tissue imaging. Color Doppler ultrasound is used for ultrasonic imaging, measurement and blood flow movement information collection for clinical ultrasonic diagnostic examinations. The probe can pass through the esophagus, blood vessels, and internal tissues of the human body during surgery.
公开号为CN114916955A的一种基于超声波技术的无创血管内压力检测装置在现有彩超设备上进行改进，在操作人员手持彩超探头进行目标血管彩超的过程中，可直接进行目标血管内压力的检测，操作方便，不仅可以测量动脉的压力，还可以测量静脉内的压力。本检测装置对动脉内压力的检测可以反应患者的动脉血压，即时无创，且在患者动脉血压明显低于或高于正常值的情况下能够准确快速的测量，比原有的无创血压更快捷，比原有的有创血压检测操作实施更简单且风险更低；本检测装置填补了原有无创压力检测所没有的静脉压力测定，如对于中心静脉压力的测定，改变了原有的测量中心静脉压力必须进行穿刺置管测压的方式，减少了患者的创伤，并且可以更快捷方便的检测颈内静脉压力，当颈内静脉于右心房处于同一水平面时，所测得的颈内静脉压力即为中心静脉压。The invention discloses a non-invasive intravascular pressure detection device based on ultrasonic technology, which is published as CN114916955A. The device is improved on the existing color Doppler ultrasound equipment. When the operator holds the color Doppler ultrasound probe to perform color Doppler ultrasound of the target blood vessel, the pressure in the target blood vessel can be directly detected. The device is easy to operate and can measure not only the pressure of the artery but also the pressure in the vein. The detection of intra-arterial pressure by the detection device can reflect the patient's arterial blood pressure, which is instant and non-invasive. When the patient's arterial blood pressure is significantly lower than or higher than the normal value, the device can accurately and quickly measure the pressure. The detection device is faster than the original non-invasive blood pressure detection and simpler to implement and has lower risk than the original invasive blood pressure detection. The detection device fills the venous pressure measurement that the original non-invasive pressure detection does not have. For example, for the measurement of central venous pressure, the device changes the original method of measuring central venous pressure by puncturing and placing a catheter for pressure measurement, which reduces the trauma of the patient. The device can detect the internal jugular vein pressure more quickly and conveniently. When the internal jugular vein is at the same level as the right atrium, the measured internal jugular vein pressure is the central venous pressure.
但在实现上述技术方案的过程中，发现上述技术方案存在如下技术问题：However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:
现有基于超声波技术的无创血管内压力检测装置通过设置在探头一端设置带有连接组件的水囊，借助水囊内外的压力差，使水囊内部压力发生变化，可以在进行血管内压力检测工作，但根据其工作原理，难以在超声探头于体表进行超声检测时，获取超声探头对检测位置施加的压力，不利于避免患者被检测部位伤口崩裂。The existing non-invasive intravascular pressure detection device based on ultrasonic technology has a water bag with a connecting component installed at one end of the probe. The pressure inside the water bag changes due to the pressure difference between the inside and outside of the water bag, so that the intravascular pressure detection can be performed. However, according to its working principle, it is difficult to obtain the pressure applied by the ultrasonic probe to the detection position when the ultrasonic probe is performing ultrasonic detection on the body surface, which is not conducive to avoiding the rupture of the wound at the detected part of the patient.
实用新型内容Utility Model Content

具体实施方式DETAILED DESCRIPTION
本申请实施例中的技术方案为解决上述背景技术的问题，总体思路如下：The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
实施例1：Embodiment 1:
本实施例介绍了一种具有压力检测功能的彩超探头的具体结构，具体参照图1-图4所示，包括彩超探头主体1、设置于彩超探头主体1一端中心处的超声检测区3和设置于彩超探头主体1一端内部，且位于超声检测区3一侧中心的压力检测结构4，彩超探头主体1的一端设置有连接线2，压力检测结构4均包括检测座套401，检测座套401的内部设置有滚珠403，滚珠403的一侧设置有限位球座404，限位球座404的一侧设置有压力传感器405，压力传感器405的一侧设置有调节件406；This embodiment introduces a specific structure of a color ultrasound probe with a pressure detection function, as shown in Figures 1 to 4, including a color ultrasound probe body 1, an ultrasonic detection area 3 arranged at the center of one end of the color ultrasound probe body 1, and a pressure detection structure 4 arranged inside one end of the color ultrasound probe body 1 and located at the center of one side of the ultrasonic detection area 3. A connecting line 2 is arranged at one end of the color ultrasound probe body 1, and the pressure detection structure 4 includes a detection seat cover 401, a ball 403 is arranged inside the detection seat cover 401, a limited ball seat 404 is arranged on one side of the ball 403, a pressure sensor 405 is arranged on one side of the limited ball seat 404, and an adjusting member 406 is arranged on one side of the pressure sensor 405;
其中，调节件406将压力传感器405压在限位球座404的一侧，使压力传感器405在检测座套401的内部检测滚珠403向限位球座404一侧施加的压力；The adjusting member 406 presses the pressure sensor 405 on one side of the limiting ball seat 404, so that the pressure sensor 405 detects the pressure applied by the ball 403 to the limiting ball seat 404 inside the detection seat sleeve 401;
其次，为了保证彩超探头主体1在移动检测过程中，压力传感器405依旧可以检测彩超探头主体1检测过程中施加的压力，如图2和图3所示，检测座套401一端的内部和限位球座404一端的内部均加工有球槽，滚珠403适配于两个球槽之间，可以使滚珠403在检测座套401和限位球座404之间滚动；Secondly, in order to ensure that the pressure sensor 405 can still detect the pressure applied by the color Doppler ultrasound probe body 1 during the mobile detection process, as shown in FIGS. 2 and 3 , the inside of one end of the detection seat cover 401 and the inside of one end of the limiting ball seat 404 are both processed with ball grooves, and the ball 403 is adapted between the two ball grooves, so that the ball 403 can roll between the detection seat cover 401 and the limiting ball seat 404;
再而，为了可以控制滚珠403从彩超探头主体1内部向外部裸露的长度，如图1和图2所示，检测座套401的一端加工有调节棱柱402，通过使滚珠403由调节棱柱402的内部伸出，当调节检测座套401和彩超探头主体1的螺纹连接情况时，可以控制滚珠403从彩超探头主体1内部伸出的长度。Furthermore, in order to control the length of the ball 403 exposed from the inside of the color ultrasound probe body 1 to the outside, as shown in Figures 1 and 2, an adjustment prism 402 is processed at one end of the detection seat cover 401. By allowing the ball 403 to extend from the inside of the adjustment prism 402, when the threaded connection between the detection seat cover 401 and the color ultrasound probe body 1 is adjusted, the length of the ball 403 extending from the inside of the color ultrasound probe body 1 can be controlled.
通过采用上述技术方案：By adopting the above technical solution:
上述设计通过调节检测座套401与彩超探头主体1的螺纹连接情况，使压力检测结构4的一端由彩超探头主体1的内部凸起，并调整其凸起部分的长度，当利用彩超探头主体1上的超声检测区3进行超声检测工作时，检测座套401内部的滚珠403与患者皮肤贴合，在彩超探头主体1移动的过程中，滚珠403在检测座套401和限位球座404之间滚动，并向限位球座404施加压力，使压力传感器405得到压力信号，便于在检测过程中，控制彩超探头主体1对皮肤表面施加的压力，避免患者皮肤受较大压力，导致被检测部位伤口崩裂。The above-mentioned design adjusts the threaded connection between the detection seat cover 401 and the color ultrasound probe body 1 so that one end of the pressure detection structure 4 protrudes from the inside of the color ultrasound probe body 1, and adjusts the length of its protruding part. When the ultrasonic detection area 3 on the color ultrasound probe body 1 is used for ultrasonic detection, the ball 403 inside the detection seat cover 401 fits against the patient's skin. During the movement of the color ultrasound probe body 1, the ball 403 rolls between the detection seat cover 401 and the limiting ball seat 404, and applies pressure to the limiting ball seat 404, so that the pressure sensor 405 obtains a pressure signal, which is convenient for controlling the pressure applied by the color ultrasound probe body 1 on the skin surface during the detection process, so as to avoid the patient's skin being subjected to greater pressure, which may cause the wound of the detected part to rupture.
实施例2：Embodiment 2:
以实施例1为基础，本实施例介绍了调节件406的具体结构，调节件406包括螺纹块4063，螺纹块4063的一侧加工有压柱4061，螺纹块4063的另一侧加工有紧固棱柱4062；Based on Example 1, this example introduces the specific structure of the adjusting member 406. The adjusting member 406 includes a threaded block 4063. A pressure column 4061 is processed on one side of the threaded block 4063, and a fastening prism 4062 is processed on the other side of the threaded block 4063.
其中，螺纹块4063螺纹式连接在检测座套401的内部，限位球座404和压力传感器405均滑动式连接在检测座套401的内部，通过调节螺纹块4063和检测座套401的螺纹连接情况，可以推动压力传感器405在检测座套401的内部滑动，调整限位球座404和压柱4061对压力传感器405施加的压力；The threaded block 4063 is threadedly connected to the inside of the detection seat cover 401, and the limit ball seat 404 and the pressure sensor 405 are both slidably connected to the inside of the detection seat cover 401. By adjusting the threaded connection between the threaded block 4063 and the detection seat cover 401, the pressure sensor 405 can be pushed to slide inside the detection seat cover 401, and the pressure applied by the limit ball seat 404 and the pressure column 4061 to the pressure sensor 405 can be adjusted;
其次，为了方便将走线槽口5内部的导线从检测座套401的内部引出，如图3所示，调节件406的内部加工有走线槽口5，走线槽口5由调节件406的中心向边缘延伸，使螺纹块4063的中心与四周相连通，压力传感器405上的导线径走线槽口5的内部穿过，不会影响螺纹块4063和检测座套401的螺纹连接工作。Secondly, in order to facilitate the leading of the wires inside the wiring slot 5 from the inside of the detection seat cover 401, as shown in Figure 3, the inside of the adjusting member 406 is processed with a wiring slot 5, and the wiring slot 5 extends from the center to the edge of the adjusting member 406, so that the center of the threaded block 4063 is connected with the surrounding area, and the wires on the pressure sensor 405 pass through the inside of the wiring slot 5, which will not affect the threaded connection between the threaded block 4063 and the detection seat cover 401.
通过采用上述技术方案：By adopting the above technical solution:
上述设计通过调节件406上的螺纹块4063与检测座套401螺纹连接，在控制压柱4061向压力传感器405的一侧运动时，可以控制压力传感器405初始受压情况，有利于矫正彩超探头主体1检测之前，压力传感器405受压的初始压力数据，从而保证检测精度；The above design is threadedly connected to the detection seat sleeve 401 through the threaded block 4063 on the adjusting member 406. When the pressure column 4061 is controlled to move toward one side of the pressure sensor 405, the initial pressure condition of the pressure sensor 405 can be controlled, which is conducive to correcting the initial pressure data of the pressure sensor 405 before the color Doppler ultrasound probe body 1 is detected, thereby ensuring the detection accuracy;
同时，走线槽口5内部的导线经调节件406上的走线槽口5穿过，从检测座套401的内部引出，便于压力传感器405的接线工作，且走线槽口5由调节件406的中心向边缘延伸，使螺纹块4063的中心与四周相连通，不会影响螺纹块4063和检测座套401的螺纹连接工作。At the same time, the wire inside the wiring slot 5 passes through the wiring slot 5 on the adjusting member 406 and is led out from the inside of the detection seat cover 401, which is convenient for the wiring work of the pressure sensor 405, and the wiring slot 5 extends from the center to the edge of the adjusting member 406, so that the center of the threaded block 4063 is connected with the surrounding area, which will not affect the threaded connection work between the threaded block 4063 and the detection seat cover 401.
最后应说明的是：显然，上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本实用新型的保护范围之中。Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
