Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary breathing equipment, in particular to an autonomous auxiliary breathing device suitable for nuclear magnetic resonance examination. Background Art
[0002] With the advancement of modern medical technology, nuclear magnetic resonance imaging (NMR) has become an important tool for diagnosing a variety of diseases. However, during NMR scanning, patients are required to lie flat and remain motionless for extended periods, making this difficult for those with weak respiratory muscles who cannot lie flat. This is especially true for patients with neuromuscular and respiratory diseases who have developed type II respiratory failure and require noninvasive ventilation. Conventional noninvasive ventilators are electronic devices containing metal parts and cannot be brought into the MRI room. Furthermore, some patients with advanced neuromuscular diseases have affected facial, masticatory, and throat muscles. Conventional masks cover the bridge of the nose and the entire cheeks, which not only affects verbal communication but also provides a poor seal and low ventilation efficiency. To address these issues, we have developed a self-assisted breathing device that combines a nasal mask, catheter, and airbag for MRI examinations. Utility Model Content
