Problems solved by technology

This is not only time-consuming, but also easily disturbed by the surrounding environment and wearing
There are also existing ways of combining radar and vision (for example, application number 202010486719). Although the accuracy can be improved to a certain extent, it is also easily affected by interference such as wearing clothes
Based on this, the prior art has also proposed the use of neural networks for recognition. However, this learning model is relatively complex, and sometimes even requires data dimensionality reduction, thereby reducing the amount of calculations, but this brings recognition accuracy. limited technical issues

Embodiment Construction

[0031] S1: Image acquisition of patient breathing

[0032] It refers to installing camera equipment directly in front of the patient to be monitored, using the camera to collect time-sequential visual images, and transmitting the collected images to the background server in real time. The specific method is described as follows.

[0033] S1.1 A frontal image acquisition method of a patient with a binocular perspective. When the patient is breathing naturally in a basically stable state, a group of two cameras is set facing the patient to completely capture the patient's face and upper chest. Two cameras are fixed on the fixed pole parallel to the direction of the patient's upper body, and are installed sequentially along the direction of the patient's body ( figure 1 ), with a distance of about 10 cm. The actual installation distance can be fine-tuned according to the site environment and the patient's stature, so that both cameras can fully capture the patient's face and upp...

Abstract

The invention relates to a chest postoperative respiratory recovery monitoring device, which is characterized in that a visual sensor is used for acquiring images of the respiratory state of a patient, a multi-scale template is used for preprocessing the images, and meanwhile, various high-dimensional characteristic variables are used for describing the respiratory state, so that image characteristics on multiple scales can be identified; robustness of risk identification is improved, and the method is especially suitable for accurate monitoring of the breathing state of the patient in the bedridden period after thoracotomy.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a breathing recovery monitoring device after thoracic surgery. Background technique [0002] With the rapid development of artificial intelligence technology, intelligent algorithms play an increasingly important role in medical diagnosis. Thoracotomy is currently an important method for the treatment of progressive intrapleural hemorrhage, tracheobronchial injury, esophageal rupture, combined thoracoabdominal injury, heart and great vessels, and severe lung laceration. Although thoracotomy can effectively alleviate economic symptoms, the operation itself is relatively traumatic, which easily increases the risk of postoperative complications, such as edema and feney sputum. If timely and effective intervention is not given, the patient's respiratory function and physical fitness will be greatly affected. Thoracotomy is a common clinical treatment method, and it is wid...
