Patient breath-holding monitoring device and method applied to CT scanning

Abstract

The invention discloses a patient breath-holding monitoring device and method applied to CT scanning. The device includes a breathing mouthpiece, an air guide tube and a breath-holding monitoring host; the breathing mouthpiece is connected to the breath-holding monitoring host through the air guide tube to form an integrated structure, the breathing mouthpiece includes a biting part and a joint part, and a bottom opening of the biting part communicates with the joint part; the breath-holding monitoring host includes a shell, a breathing sensor and a host circuit board, the breathing sensor isconnected to the interior of a conductor groove of the host circuit board through an electric conduction patch plug, the shell is provided with a main airway and an air inlet and outlet of the breathing sensor, and the main airway of the breathing sensor communicates with the air inlet and outlet; and each end of the air guide tube is provided with a connection opening, one connection opening in one end of the air guide tube communicates with the joint part of the breathing mouthpiece, and one connection opening in the other end communicates with the main airway of the breathing sensor. When the device and method provided by the invention are implemented, the breathing mouthpiece is placed on a patient mouth to directly monitor patient breath-holding conditions during the CT scanning, so that the quality of CT scanning images is improved, and the accuracy of CT diagnosis results is improved.

Description

technical field [0001] The invention relates to the field of medical detection equipment, in particular to a patient breath-hold monitoring device and method applied to CT scanning. Background technique [0002] Radiologists often find problems such as unclear images, misdiagnosis or incomplete scans due to motion artifacts during chest and abdomen CT scans. The main reason for this is that the motion artifact produced by the patient's breathing or swallowing movement during the scanning process affects the quality of the CT scanning image, resulting in the inability to distinguish the lesion clearly. Ordinary chest examination generally requires breathing coordination twice, one for scouting and one for formal tomography. In order to avoid the increase of radiation dose caused by re-scanning and re-scanning, the amount of each inhalation of the patient should be kept as consistent as possible, and the patient should hold their breath during the scanning process. Because t...
