A breathing motion control device and system

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a respiratory movement control device and system. The system comprises the respiratory movement control device, an infrared generator and a controller, wherein the respiratory movement control device comprises a soft abdominal respiration limiting plate and two groups of soft abdominal respiration adjusting plates; the soft abdominal respiration adjusting plates are arranged on two opposite sides of the soft abdominal respiration limiting plate; a magic tape is further arranged on the soft abdominal respiration limiting plate; the soft abdominal respiration adjusting plates are provided with positioning slide bars; the soft abdominal respiration limiting plate is provided with positioning slide bar grooves suitable for the positioning slide bars; the positioning slide bars can extend into the positioning slide bar grooves, and are fixed at certain positions. The respiratory movement control device is simple in structure, has a wide application range, and is easy to operate during use; the discomfort of a patient during use is reduced, and the treatment compliance of patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a respiratory motion control device and system. Background technique [0002] Organ movement during radiation therapy is one of the important factors affecting the accuracy of treatment. Organ movement includes respiratory movement, muscle contraction, heart beat and gastrointestinal peristalsis, among which respiratory movement has the most obvious effect on radiation therapy. Respiratory movement can affect tumors in the chest, abdomen, and even the pelvis, mainly manifested in the fact that respiratory movement can lead to various artifacts in the acquisition of irradiation-related images, resulting in untrue tumor volume and location information, and inaccurate delineation of irradiation targets and normal organs. Correct, the radiation dose calculation is not accurate. Although expanding the treatment margin can overcome the deficiency related to resp...

AI Technical Summary

Problems solved by technology

The movement of the lung tumor was reduced from 8-20mm (mean 12.3mm) to 2-11mm (mean 7.0mm) by using the method of forced shallow breathing control, but the position repeatability of the abdominal compression plate was poor , Complicated operation, poor patient comfort, need for special device cooperation and specific imaging verification, etc.
