Visual airway tube-changing device

Abstract

The invention discloses a visual airway tube-changing device, which comprises a tube-changing conduit and a trachea cannula, a first air bag is mounted around a near-end side wall of the tube-changing conduit, and the first airbag is connected to a first aerating device disposed at a distal end of the tube-changing conduit through a first inflation tube; the tube-changing conduit is sleeved inside the tracheal cannula, a second airbag is mounted at a near-end side wall surrounding the trachea cannula, a second airbag is connected to a second aerating device disposed at the distal end of the trachea cannula through a second inflation tube; a camera provided with a cold light source is mounted at the near end of the tube-changing conduit, and the camera and the cold light source are connected to a display disposed at the distal end of the tube-changing conduit through power lines. The device utilizes a visualization technology to clearly observe the oral cavity and the throat structure, quickly and effectively establishes an emergency artificial airway, and guides the replacement of the tube-changing conduit, reduces airway damage, effectively solves the problem of uncertainty difficult airway, and protects ventilation safety.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of airway tube changing device, in particular to a visualized airway tube changing device. Background technique [0002] In clinical work, when patients need mechanical ventilation, tracheal intubation and double-lung ventilation are routinely used in clinical practice. Or perform unilateral lung occlusion and one-lung ventilation during thoracic surgery. Endotracheal tubes have been widely used as an important airway tool for assisted ventilation of patients, which can quickly and effectively establish artificial airway. However, due to the complexity of the anatomical structure of the human body and the differences in the tolerance of the airway mucosa, problems such as airway mucosal damage, difficulty in intubation, and displacement of the endotracheal endotracheal tube lead to poor ventilation and even the tube's detachment from the trachea often occur. Ventilation failure, a...
