Trachea cannula guide wire

Abstract

The invention discloses a trachea cannula guide wire, which comprises a handle, a metal tube matched with a trachea cannula and an auxiliary device convenient for a user to see a trachea orifice clearly, and the metal tube comprises a first linear part connected with the handle and a fine adjustment part capable of extending into the oral cavity of a patient along with the trachea cannula. The shape of the fine adjustment part is matched with the path from the oral cavity to the trachea orifice. According to the trachea cannula guide wire, the metal tube is used for replacing a traditional guide wire, due to the fact that the hardness of the metal tube is large, the guide wire body is not prone to deformation under the action of external force, and shaping is more stable; and due to the metal characteristic of the metal tube, the fine adjustment part can perform small-angle fine adjustment shaping to adapt to different patients, so that the anatomical structures of the patients are met to the greatest extent, and intubation operation is facilitated. Moreover, a plastic sheath on the surface of the original guide wire is removed, the metal tube can be directly disinfected in an alcohol wiping manner during use, the operation is simple and convenient, and the possibility that the trachea cannula is polluted is reduced.

Description

Technical field[0001]This application relates to the field of medical devices, and more particularly to a tracheal intubation guide wire.Background technique[0002]In the current medical treatment, patients with respiratory failure and respiratory inhibition require first aid or patient surgery requires general hemp, and the patient needs to be tracheal intubation operation, and the tracheal intubation guide wire is required to assist the intubation. At present, the traditional tracheal intubation guide wire is free to shape freely, the tracheal intubation guide is a wire of about 40 cm long and a diameter of about 4 mm and has an insulating outer skin, in conducting a trachea The guide wire is inserted into the tracheal intubation in the intubation operation, and then manually shaped, and insert the tracheal intubation into the human air tube in the illumination of the laryngoscope and the laryngoscope light to complete the tracheal intubation. The hardness of the traditional trache...

Problems solved by technology

[0004] In order to overcome the problems existing in the related technologies at least to a certain extent, the purpose of this application is to provide a tracheal intubation guide wire, which can solve the problem that the traditional tracheal intubation guide wire is easily deformed by external force or cannot be effectively shaped after being shaped. And after repeated use, it becomes curved and uneven, which increases the difficulty of intubation operation, and the plastic skin on its surface is not conducive to disinfection and is easy to fall off, causing contamination of the tracheal intubation
