Description

Endotracheal Tube with Oxygen Tube

technical field

The utility model belongs to the field of devices for inputting medium into a human body, in particular to an intubation body with oxygen input branch tubes for intubation patients.

Background technique

The intubation body refers to the technology of placing a special endotracheal tube into the trachea through the glottis. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration.

Usually the intubation body includes the intubation body, the air bag sleeved on the front end of the intubation body and the valve for controlling the air bag. The pressure in the tube makes the patient feel comfortable, and usually the cannula body needs to be left in the patient's body. In the hospital, there are often patients with indwelling intubation body and tracheotomy. These patients usually need routine oxygen inhalation. At present, the oxygen inhalation device in the hospital is a double-lumen oxygen inhalation tube. When using it, the double-lumen oxygen inhalation tube needs to be inserted In the cannula body, oxygen is passed through the double-lumen oxygen inhalation tube, and when the double-lumen oxygen inhalation tube is inserted into the trachea, the double-lumen oxygen inhalation tube is located in the inner diameter of the intubation body and will occupy the inner space of the intubation body, thereby The effective inner diameter of the cannula body is reduced. When the patient inhales oxygen, the carbon dioxide gas exchanged through the lungs needs to be discharged from the cannula body. However, when the effective inner diameter of the cannula body becomes smaller, the ventilation effect is poor.

Utility model content

The technical problem to be solved by the utility model is to provide a belt that avoids affecting the ventilation effect in view of the existing intubation body occupying the effective space of the intubation body when the double-chamber oxygen inhalation tube is inserted, resulting in poor ventilation effect. Endotracheal tube with oxygen manifold with separate oxygen manifold connector.

In order to solve the above-mentioned technical problems, the utility model provides the following technical solutions: a tracheal intubation tube with an oxygen branch tube, including an intubation tube body, an air bag sleeved on the front end of the intubation body body, and a valve for controlling the air bag on the side of the intubation body body , also includes an oxygen branch pipe and a connecting device, the connecting device includes a first connecting pipe and a second connecting pipe, the first connecting pipe is arranged on the rear end side of the intubation body and communicates with the intubation body, the first connecting pipe and the second connecting pipe The connecting pipe is detachably connected, and the oxygen branch pipe is detachably connected with the tail of the second connecting pipe.

Adopting the tracheal intubation tube with oxygen branch tube of the utility model, the connecting device connects the oxygen branch tube and the intubation tube body, and the first connecting tube is arranged on the intubation tube body. On the one hand, the first connecting tube is used as a special connecting tube, Compared with the direct connection of the oxygen branch tube to the wall of the intubation body, it has good combination and good sealing performance to avoid air leakage; on the other hand, the first connector and the second connector are detachably connected, and the first connecting tube is connected to the second The tube is used as a special connection joint. Compared with the connection between the oxygen branch tube and the intubation body using a soft tube wall, the connection and disassembly operations are more convenient. Third, the oxygen branch tube and the second connecting tube are detachably connected. Normally, the oxygen branch tube It is connected with the second connecting pipe as a whole. When using it as a whole, it can be connected with the first connecting pipe through the second connecting pipe. When the oxygen branch pipe is damaged or needs to be replaced, the second connecting pipe can be connected with the first connecting pipe. The oxygen branch pipe can be disassembled and replaced to avoid waste.

In the tracheal intubation tube with oxygen branch of the utility model, the intubation body is left in the patient's trachea, and the second connecting tube is connected to the oxygen branch as a whole and sterilized for use. When oxygen needs to be introduced, the integrated oxygen The branch pipe and the second connecting pipe are taken out, and the second connecting pipe is connected with the first connecting pipe, so that the oxygen branch pipe is communicated with the intubation body, and oxygen is introduced, and then exhaled from the end of the intubation body after ventilation. Compared with the existing method of directly inserting the double-lumen oxygen cannula into the cannula body, a connection device for connecting the oxygen branch pipe is reserved on the side wall of the cannula body, and the method of directly connecting the oxygen branch pipe during use can avoid oxygen The branch pipe occupies the effective space of the inner diameter of the cannula body, and the effective space of the cannula body remains unchanged. Therefore, oxygen is introduced from the oxygen branch pipe, passes through the oxygen branch pipe, the second connecting pipe, and the first connecting pipe, and enters the intubating body. After the human body is ventilated, the exchanged carbon dioxide gas can be discharged from the end of the intubation tube body, and the ventilation effect is always consistent.

Further, the inner wall of the first connecting tube is stepped, and the small-diameter end of the step is connected to the cannula body; the outer wall of the second connecting tube is also stepped, and the outer wall of the first connecting tube is connected to Inner wall fit. The stepped first connecting pipe and the second connecting pipe are mated and connected. After the gas is introduced, the air pressure direction is from the second connecting pipe to the first connecting pipe. Therefore, when the second connecting pipe is inserted into the first connecting pipe, the second The small-diameter end of the connecting pipe is inserted into the small-diameter end of the first connecting pipe, and after gas is passed through, the large-diameter end of the second connecting pipe is under the pressure of the gas, and its large-diameter end is close to the small-diameter end of the first connecting pipe. When inserting, the second connecting pipe is closely connected with the first connecting pipe; in addition, when connecting, only the small-diameter end of the second connecting pipe needs to be inserted into the large-diameter end of the first connecting pipe, and the operation is convenient.

Further, the outer wall of the small-diameter end of the front end of the second connecting pipe is a tapered surface, and the small-diameter end of the tapered surface coincides with the small-diameter end of the second connecting pipe. The small-diameter end of the tapered surface of the second connecting pipe does not need to match the size when inserting the first connecting pipe. When the small end face is inserted into the large end face, the insertion is more convenient and fast. point contact with the first connecting pipe, the connection is tighter.

Further, the connecting device further includes a pipe plug connected to the tail of the first connecting pipe. The tube plug is convenient to seal the end of the first connecting tube with the tube plug when the oxygen branch tube is not used, so as not to affect the use of the intubation tube body.

Further, one side of the pipe plug is flexibly connected to the outer wall of the first connecting pipe. The flexible connection is connected through a flexible connector to avoid missing and falling of the pipe plug.

Further, the first connecting pipe is integrally formed with the cannula body, and the second connecting pipe is threadedly connected with the oxygen branch pipe. Usually, the first connecting tube and the intubation tube body do not need to be disassembled, therefore, they are integrally formed, and the sealing performance is better; the second connecting tube is threadedly connected with the oxygen branch pipe, on the one hand, the sealing performance is good, and on the other hand, the operation is convenient.
