Description

Pneumatic nose and mouth exchanger

technical field

The invention relates to a pneumatic mouth and nose exchanger.

Background technique

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 patients. Many critically ill patients in the ICU require endotracheal intubation to establish an artificial airway and perform artificial ventilation. There are also some critically ill patients in the ICU who do not need mechanical ventilation, but they often need tracheal intubation due to difficulty in expulsion of sputum due to lung infection or poor ventilation due to some reasons (such as tongue base falling back caused by cerebrovascular accident) Establish an artificial airway to keep it open and solve the problems of ventilation and expectoration.

At present, there are patients who have poor tolerance to oral tracheal intubation, manifested as irritability, insisting on extubation, and sometimes even extubation by themselves, resulting in ventilation obstruction and suffocation. Therefore, the commonly used method in clinical practice is: directly pull out the oral tracheal intubation, and replace it with nasal vision intubation; However, there are the following defects: (1) Difficulty factor: The adverse stimulation of the laryngoscope to the throat during orotracheal intubation makes patients fearful of changing the tube, resulting in uncooperative operation. It is already very difficult to intubate the tube, and it is even more difficult to intubate through the nasal cavity again after extubation; (2) If the tube replacement fails, mechanical ventilation cannot be performed, which may cause dyspnea and hypoxia, and even life-threatening; (3) Due to the tube replacement technique Difficulty, high risk, easy to cause medical disputes.

Contents of the invention

The purpose of the present invention is to provide a pneumatic mouth-nose exchanger, which solves the problems in the prior art that tube replacement technology is difficult, high risk, and prone to tube replacement failure.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

Pneumatic mouth-nose exchanger, including a flexible tube, a connecting line is arranged inside the flexible tube, and both ends of the connecting line are located outside the flexible tube, and one end is provided with a suction body which is convenient for inhaling or spitting out the human body with pneumatic , the diameter of the connecting wire is not greater than 3mm.

Further, a pulling wire is connected to the stool suction body, and the diameter of the pulling wire is not greater than 3mm.

Still further, the connecting wire is composed of a thin wire and a supporting wire connected thereto, the thin wire is connected to the suction body, and the supporting wire is located in the hose and extends to the outside of the hose.

Furthermore, the stool suction body is a small capsule, a small ball or a small air bubble.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

(1) In the present invention, a connecting line is provided in the hose, and a suction body is provided at one end of the connecting line. When the patient needs to be intubated and inserted from the mouth, the patient only needs to swallow it and then suck it. body, and then insert the flexible tube into the patient's body along the connecting line, which does not require the use of a gastroscope, but also reduces the pain of the patient and is easy to operate; It is inserted into the patient's body along the connection line, and the situation of blind intubation will not be performed like the prior art, which reduces the pain of the patient.

(2) In the present invention, the connecting line is composed of a thin line and a support line. When intubating, the thin line acts as a traction, so that the hose can enter the human body smoothly along the suction body, and the support line has a supporting role. It is convenient for the flexible pipe to enter the human body along the traction wire under the action of the support wire during intubation.

(3) When the present invention is used clinically, the stool suction body can also be sucked from the nasal cavity and then spit out from the mouth, or the stool suction body can be swallowed from the mouth and sprayed out from the nasal cavity, so as to realize the wire and catheter connecting the nasal cavity and the oral cavity , will not cause pain to the patient again by blindly detecting intubation like the prior art.
