Portable ultrasonic pneumothorax diagnosis device

Abstract

The invention discloses a portable ultrasonic pneumothorax diagnosis device. The portable ultrasonic pneumothorax diagnosis device comprises an oscillation circuit, a high-frequency pulse generator, an ultrasonic probe, a high-frequency signal amplifier, an A / D conversion module and a pneumothorax recognition processing unit which are connected in sequence. The pneumothorax recognition processingunit is used for processing high-frequency signals after digital processing, converting ultrasonic echoes into ultrasonic images, preprocessing the ultrasonic images, carrying out image segmentation and target detection on the preprocessed ultrasonic images, recognizing whether pneumothorax is caused or not by detecting whether gas exists below a pleural line or not, and feeding back a recognitionresult, wherein preprocessing comprises filtering and noise reduction processing. The portable ultrasonic pneumothorax diagnosis device is higher in detection speed, convenient to carry and quite suitable for being applied to the rescue field.

Description

technical field [0001] The invention belongs to the technical field of pneumothorax diagnosis, and in particular relates to a portable ultrasonic pneumothorax diagnosis device. Background technique [0002] Currently, the usual diagnostic methods for pneumothorax are X-rays and CT scans. However, in the field of rescue, X-ray and CT equipment are heavy and bulky, resulting in high risk and time-consuming transfer, making it difficult to deploy at the rescue site, and it is difficult to diagnose possible pneumothorax patients at the rescue site. The existing ultrasound equipment has a simple structure, is easy to carry, and has no side effects on the human body. Therefore, in the field of rescue, the use of ultrasound has a very broad application prospect. However, due to the imaging mechanism of ultrasound, ultrasound images are often noisy, and their clarity and resolution are significantly weaker than medical images such as CT and X-ray. In addition, the use of ultrasoun...

AI Technical Summary

Problems solved by technology

However, due to the imaging mechanism of ultrasound, ultrasound images often have more noise, and their clarity and resolution are significantly weaker than medical images such as CT and X-ray.

In addition, the use of ultrasound requires very professional training, and the detection results of ultrasound are also easily affected by the clinical skill level of physicians
