Respiratory gating training device

Abstract

The invention discloses a respiratory gating training device, which comprises an abdomen bandage, a data acquisition module and a display module. A cavity is formed in the abdomen bandage, and the cavity can switch between a systolic state and a diastolic state; the data acquisition module communicates with the cavity of the abdomen bandage, and the data acquisition module is capable of generating pneumatic data in accordance with a switching process of the cavity between the systolic state and the diastolic state an drawing an oscillogram in accordance with the pneumatic data and / or generating a respiratory gating signal; and the display module is used for receiving the pneumatic data which is acquired by the data acquisition module and the oscillogram which is drawn by the data acquisition module and for displaying the pneumatic data and the oscillogram. The training device disclosed by the invention is capable of effectively training the precision of breathing movement; and the training device is low in overall cost, small in overall size, light in weight, convenient to carry and easy for using.

Description

technical field [0001] The invention relates to the technical field of respiratory gated training, in particular to a respiratory gated training device based on a high-precision air pressure sensor. Background technique [0002] In the field of medical treatment and medical imaging, some techniques to reduce organ movement caused by respiration have been proposed, such as exogenous respiration restriction, self-breathing restriction and respiratory gating technology, etc. Among them, respiratory gating technology is the most widely used technology in clinical treatment. Respiratory gating technology usually relies on airflow or external markers to track and scan organ movements in the case of synchronous respiration, and effectively compensate for the effects of respiration on organ movements. Proven respiratory gating techniques are required for treatment precision and image quality for medical imaging. [0003] Respiratory gating technology requires patients to maintain ...

AI Technical Summary

Problems solved by technology

However, due to the lack of effective training before the use of the respiratory gating technique, the accuracy of the respiratory movement during the use of the respiratory gating technique is affected, which not only delays the treatment time, increases the treatment cost, but also adversely affects the subsequent treatment effect Influence, especially for radiation therapy, imprecise localization of the lesion may even cause damage to the normal organs of the patient
