Abstract

The invention discloses an S-shaped visible hard cannula core. The S-shaped visible hard cannula core comprises a liquid crystal display, a handle and a hard tube core which are sequentially connected, wherein a camera and a light-emitting body are arranged at the outer end of the hard tube core and respectively connected with the liquid crystal display. The hard tube core is sequentially divided into a first linear section, a camber-line-shaped section, a circular arc section and a second linear section from one end to the other end, wherein the included angle formed by the tangential direction of the tail end of the circular arc section close to the camber-line-shaped section and the axis direction of the handle ranges from 2 degrees to 20 degrees, the circular arc radius of the circular arc section is 45-70mm, the central angle which the circular arc of the circular arc section faces ranges from 60 degrees to 80 degrees, and the included angle formed by the second linear section and the axis direction of the handle ranges from 50 degrees to 70 degrees. The S-shaped visible hard cannula core has the advantages of being convenient to operate, clear in images and capable of fast and accurately finishing trachea cannula inserting operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a visible hard intubation core used for guiding a patient's tracheal intubation. Background technique [0002] The laryngoscope, which is a necessary instrument for tracheal intubation in the anesthesiology department, emergency department and intensive care department of the hospital, has been widely used in clinical practice. At present, the laryngoscope with video function usually inserts the endotracheal tube with the intubation core directly into the patient's trachea under the video image provided by the camera, or uses the guide groove designed on one side of the laryngoscope to insert the endotracheal tube into the patient's trachea. The catheter is inserted into the patient's trachea along the guide groove under the guidance of the video image, such as a document CN201328799Y published by the Chinese Patent Office on October 21, 2009. The name of the ...
