Air warming type trachea cannula

Abstract

The invention discloses an air warming type trachea cannula which comprises a sealing shell, an air inlet pipe, a filter plug and a heating cavity, wherein the filter plug is installed in the sealingshell, a plurality of retaining washers are installed on the filter plug, a sleeve clamp and an air inlet valve are installed on the outer side of the sealing shell, a connecting handle is arranged atone end of the sealing shell, and the sealing shell is connected with the air inlet pipe through the connecting handle, the connecting handle is of a frame-shaped structure, the heating cavity is formed in the connecting handle, and a miniature heater used for heating air is installed in the heating cavity. The trachea cannula has the beneficial effects that on the premise that the small and convenient characteristics of a traditional trachea cannula are not changed, air entering a pipeline is preheated to a certain degree through the miniature heater composed of an electric heating wire withelectric control power, so that the temperature of the air is close to the natural breathing temperature of a human body as much as possible when the air enters the trachea of the human body, and stimulation to the human body of a patient is reduced; and through a flexible assembly structure, the filter plug, the air inlet pipe and the sealing shell are movably assembled, replacement and disinfection are convenient, and the device cost is greatly saved.

Description

technical field [0001] The invention relates to a tracheal cannula, in particular to a gas warming type tracheal cannula, which belongs to the technical field of medical aids. Background technique [0002] Tracheotomy is to incise the cervical trachea and put in a metal tracheal cannula and a silicone tracheal cannula. After intubation, perform tracheotomy under general anesthesia, open the tracheal incision with curved forceps or a tracheal incision dilator, insert a tracheal cannula with a suitable size, and insert the outer tube, immediately take out the stylet and put it into the inner tube. The endotracheal tube is sucked up, and checked for bleeding. The strap on the endotracheal tube is tied to the neck and tied into a knot for firm fixation. The incision is generally not sutured, so as not to cause subcutaneous emphysema, and finally a piece of open gauze is placed between the wound and the cannula. [0003] The general tracheal tube is made of metal or silicone st...

AI Technical Summary

Problems solved by technology

[0003] The general tracheal tube is made of metal or silicone structure, and its role is more reflected in assisting tracheal breathing. However, during use, the air entering the intake tube cannot be preheated by the upper respiratory tract of the human body. The direct entry of air that does not meet the internal temperature of the human body into the trachea may cause stress reactions in the patient, resulting in tracheal constriction and obstruction, affecting the operation process, and the traditional tracheal tube follows the principle of one-time use, which cannot be reused for resource utilization, resulting in a lot of of medical waste
