Embodiment 1

[0020] Such as figure 1 , 2 As shown, it is a nasal endotracheal tube (double cuff). The nasal endotracheal tube has double cuffs, which are located at both ends of the endotracheal tube respectively. 2. It occupies 1 / 2 arc of the cross-section of the endotracheal tube, and is located at the inflection point of the nostril of the endotracheal tube.

[0021] When the anesthesiologist performs nasal endotracheal intubation, the gas in the double cuff is evacuated. After the intubation is completed, the bronchial end cuff is inflated first. After the endotracheal tube is fixed and the position of the endotracheal tube is completely determined, the nasal end cuff is finally inflated. , so that the inflation of the nasal cuff does not interfere with the previous intubation operation. The nasal cuff should not be overfilled. The nasal cuff is located between the nasal mucosa and the endotracheal tube to prevent nasal mucosa from crushing. At the end of the operation, the first st...

Abstract

The invention relates to a nose-passing tracheal catheter with double cuffs, belongs to a medical instrument used for the anesthesiology department and is applied to the field of tracheal intubation in the anesthesiology department. The nose-passing tracheal catheter comprises the nose end cuff, the bronchus end cuff, a tracheal catheter body and others, and is characterized in that the nose-passing tracheal catheter is provided with the double cuffs which are located at the two ends of the tracheal catheter body respectively. In trachea intubation of the anesthesiology department, the tracheal catheter can be prevented from pressing and hurting the nosal mucosa and protects the nosal mucosa, in this way, medical safety is guaranteed, and the comfort degree of a patient is increased.

Description

technical field [0001] The invention relates to a nasal endotracheal catheter (double cuff), which is applied to the field of tracheal intubation in anesthesiology department. Background technique [0002] At present, the nasal endotracheal tube (single cuff) is generally used clinically for the anesthesiology department. The disadvantages are as follows: ① The nasal endotracheal tube (single cuff) is a single cuff endotracheal tube, and the cuff is located in the catheter. Bronchial end. After the catheter is inserted into the specified depth through the nose, the outer part of the catheter needs to be folded back and fixed through the nose. The hard material of the catheter and the softness of the nasal mucosa and skin at the folded part of the folded part often cause mucous membrane or skin pressure, which makes the patient's nose postoperative redness, pain and discomfort, individual or even combined infection and other postoperative complications. Therefore, it is par...
