Description

A tracheal intubation connecting device to ensure continuous oxygen supply in extubation test

technical field

The utility model belongs to the technical field of medical equipment, and in particular relates to a tracheal intubation connecting device for ensuring continuous oxygen supply in an extubation test.

Background technique

Tracheal intubation is an important rescue technique commonly used in emergency work, and it is one of the most widely used, most effective and fastest methods in respiratory management. At present, emergency tracheal intubation has become an important measure in the process of cardiopulmonary resuscitation and the rescue of critically ill patients with respiratory dysfunction, which plays a vital role in saving the lives of patients and reducing the fatality rate. And it can suck out the tracheal secretions in time, keep the airway unobstructed, and carry out effective artificial or mechanical ventilation. However, when the patient's condition improves, his consciousness is clear, his vital signs are stable, and there is an indication for extubation, the tracheal intubation needs to be removed. In order to avoid secondary intubation, an extubation test needs to be performed before pulling out the tracheal intubation. In the past, it was difficult to connect the nasal cannula and mask used in clinical practice to the tracheal intubation, which often caused the nasal cannula or mask to fall off, interrupting the oxygen supply to the patient. thereby endangering the patient's life. At the same time, it is also possible for tiny particles in the air to enter the patient's airway, causing airway reactions and worsening the patient's condition. Therefore, in order to avoid the above situation, there is an urgent need for an oxygen inhalation tube connected to a tracheal intubation tube.

Utility model content

The purpose of the utility model is to provide a tracheal intubation connecting device which ensures continuous oxygen supply in extubation test.

The utility model is realized in the following ways:

A tracheal intubation connection device for ensuring continuous oxygen supply in an extubation test, comprising an oxygen supply pipe, one end of the oxygen supply pipe is provided with an interface for an oxidation humidification bottle, the other end passes through a three-chamber ventilation conversion device, and the piercing part It is an extension of the oxygen supply pipe, and the three-chamber ventilation conversion device is a three-way pipe structure, including a first through hole, a second through hole and a third through hole, and the oxygen supply pipe passes through the first through hole. The third through hole is provided with a dust cover, and the dust cover is provided with a suction hole.

Compared with the prior art, the beneficial effects of the present utility model are:

Through the close connection of the oxygen supply tube and the tracheal intubation, the extension of the oxygen supply tube can penetrate 15 cm into the tracheal intubation tube, and oxygen is transported through the oxygen supply tube and enters the lungs of the patient through the extension of the oxygen supply tube After the gas exchange, the exhaled gas of the patient is discharged through the multiple air outlets on the first through hole of the three-chamber ventilation conversion device, which can better adjust the gas and ensure sufficient oxygen supply without causing carbon dioxide. Retention, to prevent the oxygen supply of the patient from falling off and interrupting the oxygen supply, and to reduce the occurrence of tiny particles in the air entering the patient's airway.
