S-SHAPED VISIBLE HARD INTUBATION CORE

摘要

Disclosed is an S-shaped visible hard intubation core, which is composed of a liquid crystal display, a handle and a hard core connected in sequence. An outer end of the hard core is provided with a camera and a light-emitting body, and the camera and the light-emitting body are respectively connected to the liquid crystal display. The hard core is composed of, in sequence from one end to the other end, a first straight segment, an arcuate segment, an arc-shaped segment and a second straight segment. The tangential direction to the end of the arc-shaped segment close to the arcuate segment forms an included angle of 2° to 20° with an axial direction of the handle. The arc-shaped segment has an arc radius of 45 mm to 70 mm. The arc of the arc-shaped segment subtends a central angle of 60° to 80°. The second straight segment forms an included angle of 50° to 70° with the axial direction of the handle. The advantages of the present invention are a convenient operation, sharp images and a capability of rapidly and accurately completing tracheal intubation.
