Hard tube laryngoscope suitable for a plurality of specifications of tracheal cannulas

Abstract

The invention discloses a hard tube laryngoscope suitable for a plurality of specifications of tracheal cannulas. The laryngoscope comprises a handle and a hollow hard tube, one end of the handle is connected with one end of the hard tube, a positioning body sleeved on the periphery of the hard tube is in a round table shape and has a taper angle of 1-3 degrees, and the big end of the positioning body is close to the handle. The hard tube laryngoscope has the advantages that a plurality of specifications of tracheal cannulas can be matched simultaneously, and a distance between the external end face of the hard tube and the external end face of the patient end of a tracheal cannula can be effectively guaranteed to be about 10mm, wherein the hard tube provided with a camera and an LED lamp; the laryngoscope is convenient for a doctor to operate, tracheal intubation can be finished quickly, specifications and kinds of the hard tube laryngoscopes matching with the tracheal cannulas are reduced, the cost for using the hard tube laryngoscope is reduced for a hospital, and popularization and application of the hard tube laryngoscope are facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a visual hard tube laryngoscope which can be simultaneously applied to various types of tracheal intubation and obtain good positioning. 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...

Problems solved by technology

However, because there are many specifications of tracheal intubation, according to the regulations on tracheal intubation in the "Pharmaceutical Industry Standard of the People's Republic of China YY0337.1-2002", there are 19 specifications of endotracheal intubation due to their different inner diameters and lengths that match the inner diameters. , which makes the length matching between the endotracheal tube and the rigid tube a more difficult problem to solve

If the outer end surface of the endotracheal tube exceeds the outer end surface of the hard tube by more than 15mm, the patient's end of the endotracheal tube will lose the shape of the hard tube, which is not conducive to the smooth insertion of the endotracheal tube, and the flexible endotracheal tube The end of the patient may even block the light of the camera, making it difficult for the doctor to determine the insertion direction of the endotracheal tube; If the front end of the hard tube is exposed outside the end of the endotracheal tube patient, the hard tube will be in contact with the patient's throat, and the hard tube will be in contact with the patient's throat. It is made of metal, which may cause damage to the patient's upper respiratory tract, and the patient's throat is attached to the outer end of the hard tube, which will also cause the camera to lose its proper function; if it is specially equipped for each specification of tracheal intubation A kind of rigid laryngoscope, the promotion and application of expensive rigid laryngoscope will be greatly reduced
