Laryngeal mask ventilation monitoring method and equipment

Abstract

The invention discloses a laryngeal mask ventilation monitoring method and device. The method comprises the steps that video image information during laryngeal mask ventilation is collected in real time; extracting object apparent characteristics of a single-frame image in the video image information; extracting pixel optical flow features of multiple frames of images in the video image information; carrying out region detection and key point detection on the apparent characteristics of the object, and generating predicted key point positions; performing optical flow prediction on the pixel optical flow features, and generating motion prediction information; and combining and analyzing the predicted key point position and the motion prediction information to obtain optical flow information of the key point position. By adopting the laryngeal mask ventilation monitoring method and equipment, the ventilation process of a laryngeal mask in an operation can be monitored in real time through a visualization technology and a synchronous image analysis technology, so that the operation efficiency is improved. The risks include whether the laryngeal mask shifts or not and whether the respiratory rate is abnormal or not, doctors of the anesthesiology department are reminded to examine and deal with existing problems in time, safety is guaranteed, and adverse events in airway management are prevented.

Description

technical field [0001] The invention relates to the field of intelligent medical devices, in particular to a method and equipment for monitoring ventilation of a laryngeal mask. Background technique [0002] At present, visual intubation technology has been widely used, including placing an endotracheal tube or a laryngeal mask under direct vision of a video laryngoscope, which ensures the successful implementation of mechanical ventilation. [0003] However, during the operation, changes in the patient's position and slight swallowing activities in the larynx may lead to changes in the position of the laryngeal mask, resulting in increased intragastric pressure, hypoventilation, and even suffocation. These problems are often difficult to detect in time through conventional ventilator parameters. Airway management carries risks. [0004] In order to ensure the stability and safety of the laryngeal mask ventilation process, it is necessary to continuously monitor the positio...
