Description

A nasotracheal tube (double cuff)

technical field

The invention relates to a nasal endotracheal catheter (double cuff), which is applied to the field of tracheal intubation in anesthesiology department.

Background technique

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 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 particularly necessary to design a tracheal tube to prevent nasal mucosal pressure injury. In this invention, the endotracheal catheter is designed as a double cuff, and the nasal end cuff of the catheter is positioned between the nasal mucosa and the endotracheal catheter during use to prevent nasal mucosa from being crushed. Avoid postoperative nasal mucosa redness, pain and discomfort. Ensure medical safety and improve patient experience.

Contents of the invention

The invention relates to a nasal endotracheal catheter (double cuff), which is applied in the field of tracheal intubation in anesthesiology department.

In order to solve the problems of the technologies described above, the technical solution of the present invention is:

A nasotracheal tube (double cuff). The invention belongs to a medical instrument for anesthesiology department and is applied in the field of tracheal intubation in anesthesiology department. Including nasal end cuff, bronchial end cuff, endotracheal tube, etc. It is characterized in that the nasal endotracheal catheter has double cuffs, which are respectively located at both ends of the endotracheal catheter.

Preferably, the above-mentioned nasal endotracheal tube (double cuff), the nasal endotracheal tube has double cuffs, which are respectively located at both ends of the endotracheal tube, and the bronchial end cuffs play a role in ① closing the tracheal opening and preventing gas leakage; ② fixing the endotracheal tube , to prevent detachment ③ to prevent the inhalation of stomach contents. The nasal end cuff prevents the endotracheal tube from crushing the nasal mucosa and protects the nasal mucosa.

Preferably, the above-mentioned nasal endotracheal catheter (double cuff), the length of the nasal end cuff is 2-4cm.

Preferably, in the above-mentioned nasal endotracheal catheter (double cuff), the nasal end cuff is located at the nostril reflexion of the nasal endotracheal catheter.

Preferably, the above-mentioned nasal endotracheal catheter (double cuff), the arc length of the cross-section of the nasal end cuff is 1/3-1/2 of the arc length of the cross-section of the bronchial end cuff, that is, it occupies 1/2 of the arc length of the cross-section of the endotracheal catheter. 1/3 of the arc length - 1/2 arc.

Preferably, the above-mentioned nasal endotracheal catheter (double cuff), the gas in the double cuff is generally in an evacuated state, and after the intubation is completed, it is properly inflated according to the size of the nostril.

Preferably, the above-mentioned nasal endotracheal tube (double cuff) and the type of endotracheal tube are selected. The type of the endotracheal endotracheal tube is generally half a size smaller than that of the oral endotracheal tube. The endotracheal tube is suitable for most adults, and the following method can be used for children: (age/4)+4=tube model.

Beneficial effect:

The invention can prevent the nasal mucosa from being crushed by the endotracheal tube during the anesthesia tracheal intubation, and protect the nasal mucosa, thereby increasing the patient's comfort. Avoid postoperative nasal mucosa redness, pain and discomfort. Improved patient experience.

Detailed ways

Example 1

As shown in Figures 1 and 2, it is a nasal endotracheal tube (double cuff). The nasal endotracheal tube has double cuffs, which are respectively located at both ends of the endotracheal tube. 1/2 of the width of the sac, that is, 1/2 of the arc of the cross-section of the endotracheal tube, is located at the inflection point at the nostril of the endotracheal tube.

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 step of extubation is to evacuate the air in the nasal cuff so as not to hinder the subsequent extubation. The endotracheal tube was then removed.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
