Embodiment 1

[0020] Such as figure 1 As shown in the pneumatic mouth-nose exchanger, a connecting line 2 is arranged inside the flexible tube 1, and both ends of the connecting line 2 are located outside the flexible tube 1, and one end is provided with a convenient suction device for inhaling or spitting out the human body. body 3, the diameter of the connecting line 2 is not greater than 3mm, in order to smoothly inhale or swallow the stool suction body through the airflow into the human body, so the stool suction body 3 is a small capsule, a small ball or a small air bubble. For example, a small capsule is used as the stool suction body. When the patient needs to be intubated, when inserting it from the mouth, the patient only needs to swallow the stool suction body, and then insert the hose along the connecting line into the patient's body without using a gastroscope. It can also reduce the patient's pain and is easy to operate; when the trachea needs to be inserted from the nasal cavi...

Embodiment 2

[0023] Such as figure 2 As shown, the difference between Embodiment 2 and Embodiment 1 is that the end of the pull wire away from the suction body is also fixedly connected with a dropper, the end of the pull wire is located in the mouth of the dropper, and the end of the pull wire The diameter is exactly equal to the inner diameter of the dropper nozzle. When the suction body needs to be pulled out or the hose needs to be inserted, water can be slowly dripped through the dropper to moisten the traction line to ensure that the traction line will not cause damage to the human body.

Abstract

The invention discloses a pneumatic oral-nasal exchanger which solves the problems of high difficulty, high risk and easiness in tube exchanging failure of a tube replacement technology in the prior art. The pneumatic oral-nasal exchanger comprises an air tube, a connecting line with the diameter not more than 3mm is arranged in the air tube, two ends of the connecting line are both positioned outside the air tube, and one end of the connecting line is provided with a convenient inhalation body convenient for inhaling or swallowing into a body. When the air tube needs to be inserted from an oral cavity, a patient only needs to swallow the convenient inhalation body, then the air tube is inserted into the body of the patient along the connecting line without a gastroscope, and pain of the patient can be relieved, and operation is facilitated; and when the air tube needs to be inserted from a nasal cavity, the patient only needs to inhale the convenient inhalation body from the nasal cavity, then the air tube is inserted into the body of the patient along the connecting line, blind intubation in the prior art can be avoided, and pain of the patient is relieved.

Description

technical field [0001] The invention relates to a pneumatic mouth and nose exchanger. Background technique [0002] Endotracheal intubation is an emergency technique that inserts a suitable catheter into the trachea to quickly relieve airway obstruction and ensure oxygen supply. It is one of the reliable ways to establish an artificial airway, and its characteristics are: ① It can keep the airway open in any position; ② It is convenient for breathing management or assisted or controlled breathing; ③ It reduces the dead space and reduces the resistance of the airway, thereby increasing the effective gas. exchange volume; ④ facilitate the removal of tracheal, bronchial secretions or pus and blood; ⑤ prevent the risk of aspiration and suffocation caused by vomiting or reflux; ⑥ facilitate intratracheal medication (inhalation or instillation) for local treatment in the respiratory tract. Endotracheal intubation is an important part of the rescue process for critically ill pati...
