Problems solved by technology

[0003]In order to overcome the oblique shape of the front end of the existing endotracheal tube, once it is blocked when passing through the glottis, it is easy to cause laryngeal damage, fiberoptic bronchoscope or intubation bougie is used to assist the trachea During intubation and retrograde tracheal intubation, the front end of the endotracheal tube is easily blocked, resulting in a certain failure rate of intubation. I designed this new type of endotracheal tube. The front end is arrow-shaped, which can avoid the damage of the tube to the larynx. When intubation bougie-assisted intubation or retrograde tracheal intubation, the tube delivery is easier and the success rate of intubation will be greatly improved

Embodiment Construction

[0012] The method of anesthesia for side-hole tracheal intubation is the same as that of general tracheal intubation. The inner diameter of the tracheal tube commonly used in clinic is 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, so the inner diameter of the tracheal tube body of this design is also consistent with the above. The only difference is that the front end of the catheter is arrow-shaped. The inner diameter of the opening of the catheter indicated by the arrow is 5-6.5 mm, so that the suction tube, tracheal intubation probe, and fiberoptic bronchoscope can pass smoothly. The intubation method of the arrow side-hole tracheal tube for general patients is the same as the usual intubation. When it is estimated that there is difficulty in tracheal intubation, first insert the tracheal intubation probe into the trachea, and then put the tracheal tube into the intubation probe. , Delivery tube, the front end of the arrow side hole tracheal tube can "tightly hug" the p...

Abstract

The invention discloses an arrowheaded tracheal tube with a side opening, which has a round and blunt front end. An intubation bougie, a fiberoptic bronchoscope and a suction catheter can pass through the opening. The arrowheaded tracheal tube with the side opening can reduce intubation damage and increase the success rate of tracheal intubation.

Description

1. Technical field [0001] The invention relates to an endotracheal tube with different inner diameters with an arrow-shaped front end, a front port diameter of 5-6.5 mm and a side hole. 2. Background technology [0002] At present, the front end of the endotracheal tube widely used in anesthesiology departments at home and abroad is a beveled side hole type endotracheal tube. 1” shape) to allow easier passage of the catheter through the glottis. However, in the actual application process, we found that when it is difficult to intubate the endotrachea, the thinner the endotracheal tube is selected, the higher the success rate of intubation is. Because the slope at the front end of the endotracheal tube is relatively large, it is often easier to be blocked by the glottis, making intubation more difficult. difficulty. Repeated violent intubation can easily lead to laryngeal edema, difficulty in ventilation, and even suffocation of the patient. This is the most common cause ...
