Intubation device capable of being used for difficult airway independently or in cooperation with fiber bronchoscope

Abstract

The invention provides an intubation device capable of being used for a difficult airway independently or in cooperation with a fiber bronchoscope. The intubation device comprises an insertion guide rail, the insertion guide rail comprises a guide rail main body in a circular arc strip shape, and a T-shaped guide slot penetrating through the two circumferential ends of the guide rail main body is formed in the outer circular arc surface of the guide rail main body in a circumferential extending mode; the guide rail main body is further provided with a video hole channel which extends in the circumferential direction and penetrates through the two ends of the guide rail main body in the circumferential direction, and a transparent lens is embedded in one port of the video hole channel; a tongue depressor is connected to one end, corresponding to the embedded transparent lens, of the guide rail main body, and an operating handle is fixedly arranged at the other end, located on the inner arc surface, of the guide rail main body in the circumferential direction; and a guide marking line extending to the two ends is carved on the groove bottom wall of the T-shaped guide slot. The device is small in overall thickness, and can be used by patients with difficult airways under various conditions such as small opening degrees.

Description

technical field [0001] The invention relates to the technical field of medical endoscopy, in particular to a device for using an electronic video bronchoscope for tracheal intubation and throat diagnosis and treatment, specifically a device that can be used alone or in conjunction with a fiberoptic bronchoscope for difficult airways Intubation device. Background technique [0002] Since Cahersa, Spain invented the world's first laryngoscope in 1855, various new types of laryngoscopes have emerged. With the development of technology, in 2001, the Canadian Saturn company invented the Glidescope video laryngoscope, which revolutionized the way of tracheal intubation or laryngeal diagnosis and treatment. Therefore, video laryngoscope has been widely promoted and applied rapidly all over the world. In clinical medicine, before anesthesiologists use anesthesia machines, ventilators and other equipment for patients, they generally need to perform tracheal intubation on patients, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an intubation device that can be used alone or in conjunction with a fiberoptic bronchoscope for difficult airways. For patients who cannot insert a fiberoptic bronchoscope from the nasopharynx (for example, patients with nasopharyngeal carcinoma or patients with nosebleeds or easily injured nasal mucosa) or endotracheal tubes can only be intubated from the mouth. The laryngoscope and the laryngoscope used with it are relatively large in size and have a large curvature. As a result, the laryngoscope cannot pass through the base of the tongue, provoke the epiglottis, and even encounter some patients with limited mouth opening. It can’t be put into the mouth, or it can barely enter the mouth, and the glottis or even the epiglottis cannot be exposed. The airway can only be established through difficult airway tools such as fiberoptic bronchoscopes. No force, unable to pass through the base of the tongue, exposing the glottis, and even the epiglottis, easily slipping into the esophagus, resulting in failure of intubation
