Wearable visual ultrasonic non-invasive monitoring equipment

Technical Field

The invention relates to the technical field of ultrasonic imaging, in particular to flexible ultrasonic imaging monitoring equipment.

Background

The determination of central venous pressure is important for guiding the formulation of treatment regimens for clinically critical patients. At present, the floating catheter is placed in the inferior vena cava for determination clinically by means of an interventional operation, the method is an invasive method, and has the defects of infection, inconvenience, difficulty in long-term continuous monitoring and the like, and a noninvasive central venous pressure monitoring method is urgently needed clinically. The ultrasonic imaging can carry out non-invasive imaging on blood vessels, and the central venous pressure is found to be positively correlated with the caliber of inferior vena cava in the early period, so the idea of monitoring the central venous pressure by utilizing the ultrasonic image is provided. However, two difficulties have been found to exist: first, most of the existing ultrasound imaging devices are used for one-time scanning imaging, which is difficult to perform continuous monitoring imaging for a long time, and difficult to obtain dynamic ultrasound recording data for diagnosis and treatment of diseases and selection of surgical schemes. The reason for this is that: at present, the geometric dimension of the conventional ultrasonic probe, whether a convex array, a concave array, a linear array or an area array, is fixed. Such as a convex/concave array probe with a fixed radius of curvature of the probe, array element spacing and distribution, etc. Therefore, in order to obtain good contact, it is necessary to closely attach the ultrasonic probe to the detection site and fill up the fine gaps with an ultrasonic couplant. Even so, since the ultrasound probe is rigid, good contact is often not obtained, resulting in a great impact on imaging quality. When human tissue detects, if not soft tissue position, perhaps when the detection target surface curvature continuous variation is irregular, the probe just can't use, has caused very big inconvenience to formation of image and detection, needs medical personnel to hold fixedly in the use, consequently can't carry out continuous control formation of image. Secondly, the automatic calculation and real-time monitoring of the area of the vein can not be achieved due to the lack of artificial intelligence.
