Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic imaging, and in particular to a wearable visualized ultrasonic non-invasive monitoring device. Background Art

[0002] The measurement of central venous pressure is very important for guiding the formulation of treatment plans for critically ill patients. Currently, the only method for measuring central venous pressure in clinical practice is to place a floating catheter in the inferior vena cava during interventional surgery. This is an invasive method with the disadvantages of infection, inconvenience, and difficulty in long-term continuous monitoring. A non-invasive central venous pressure monitoring method is urgently needed in clinical practice.

[0003] Ultrasound imaging can be used for non-invasive imaging of blood vessels. We previously found that central venous pressure is positively correlated with the diameter of the inferior vena cava, so we proposed the idea of ​​using ultrasound imaging to monitor central venous pressure. However, we found that there are two difficulties: First, most of the existing ultrasound imaging equipment is used for one-time scanning imaging, and it is difficult to carry out continuous monitoring imaging for a long time, and it is difficult to obtain dynamic ultrasound video data for disease diagnosis and treatment and the selection of surgical plans. The reason is that the geometric dimensions of conventional ultrasound probes, whether convex array, concave array, linear array or surface array, are fixed. For example, convex array / concave array probes have fixed probe curvature radius, array element spacing and distribution. Therefore, in order to obtain good contact, the ultrasound probe must be placed close to the detection site and ultrasonic coupling agent must be used to fill the small gaps. Even so, since the ultrasound probe is rigid, good contact is often not obtained, resulting in a great impact on the imaging quality. When testing human tissue, if it is not a soft tissue site, or the curvature of the target surface changes continuously and irregularly, the probe cannot be used, which causes great inconvenience to imaging and testing. During use, medical staff need to hold it in their hands and fix it, so continuous monitoring imaging cannot be performed. Second, due to the lack of artificial intelligence, it is impossible to automatically calculate and monitor the venous area in real time. Summary of the invention

[0004] The purpose of the present invention is to provide a wearable visualized ultrasonic non-invasive monitoring device to obtain dynamic ultrasonic video data for diagnosis and treatment of diseases, thereby solving the above-mentioned problems existing in the prior art.
