Tracheal intubation guide groove matched with bronchofiberscope and usage method

Abstract

The invention discloses a trachea cannula guide groove matched with a bronchofiberscope and a usage method, and belongs to the field of medical instruments. The trachea cannula guide groove comprisesa catheter body and a guide hole formed in the catheter body. The guide hole comprises a clamping part arranged at the front end of the catheter body, a guide part arranged at the rear end of the catheter body and a clamping part arranged between the clamping part and the guide part; according to the tracheal intubation bronchofiberscope, the purposes of passing through the glottis and reducing physical damage to glottis accessory tissue are achieved, the clamping force of the tube body to the bronchofiberscope is improved through aperture matching of the clamping part and the clamping part, and the problem that the tracheal intubation bronchofiberscope is too soft and insufficient in supporting force under guidance of the bronchofiberscope is solved. Meanwhile, the oxygen supply device can serve as a ventilation tool to be placed in the airway under special emergency conditions, and the oxygen supply problem of the patient is temporarily solved. In the using process, glottis exposureis better, the intubation success rate is higher, physical injuries are smaller, complications are fewer. Meanwhile, the life safety of a patient is guaranteed, and the comfort of the patient in the perioperative period is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a tracheal intubation guide slot matched with a bronchoscope and a method of use. Background technique [0002] In the process of tracheal intubation, it is often encountered that the difficult airway that cannot expose the epiglottis and glottis leads to intubation failure, surgery cancellation, and life-threatening situations such as hypoxia and suffocation of patients. The video laryngoscope technique commonly used in clinical practice can sometimes only expose the epiglottis but not the glottis directly, so the existing fiberoptic bronchoscope technique is to pass the fiberoptic bronchoscope through the tracheal tube and directly enter under the epiglottis. The front-end lens is bent to directly peek at the glottis and enter the airway, thus solving the problem of exposing the glottis. However, when the endotracheal tube is inserted into the glottis along the bronchofiberoscope...

Problems solved by technology

[0002] In the process of tracheal intubation, it is often encountered that the difficult airway that cannot expose the epiglottis and glottis leads to the failure of intubation, the cancellation of the operation, and the life-threatening situation of the patient's hypoxia and suffocation.

The video laryngoscope technique commonly used in clinical practice can sometimes only expose the epiglottis but not the glottis directly, so the existing fiberoptic bronchoscope technique is to pass the fiberoptic bronchoscope through the tracheal tube and directly enter under the epiglottis. The front-end lens is bent to directly peek at the glottis and enter the airway, thus solving the problem of exposing the glottis. However, when the endotracheal tube is inserted into the glottis along the bronchofiberoscope, it often happens that the bronchofiberoscope is too soft and has no support. The endotracheal intubation failed to insert the airway; and the wedge-shaped opening at the front end of the endotracheal tube is similar to a physical oblique plane, which will also cause a certain degree of cutting and damage to the vocal cords and nearby tissues on both sides of the glottis. The friction caused by the glottis and throat edema and bleeding, affecting the patient's life safety, postoperative recovery and perioperative comfort
