An optical fiber guided insertion and positionable endotracheal intubation tube

Abstract

The discloses a fiber guided insertion and positionable tracheal cannula, comprising an optical fiber connected with an LED light generator that is connected with a low-voltage adapter; also comprising a tracheal cannula, with the tail end of the optical fiber fixed to the inner wall of the tracheal cannula which seals a cuff. When the tracheal cannula is under insertion, pre-intubation preparation is made, a guide wire is placed in to suitably shape the front end of the cannula and the optical fiber, the optical fiber is connected with the light generator and a low-voltage direct-current power supply, a switch of ta light source is turned on, and the tracheal cannula can be inserted with visual inspection; after inserting the tracheal cannula and when there is a need for positioning the cannula, it is possible to make the optical fiber luminescent again to understand a cuff release position as an insertion position through light from the skin, and it is also possible to understand an insertion position through an X-ray film and a specially designed transverse marker on the cuff; the cannula can also be used in implantation guide for tracheotomy cannula and positioning for position determination.

Description

technical field [0001] The invention relates to the field of medical instruments, more precisely, it relates to an endotracheal intubation tube with an optical fiber guiding intubation tube. Background technique [0002] The traditional light rod or light cable guided tracheal intubation often has unsatisfactory brightness, curvature or inaccuracy due to structural and material defects, and may have thermal damage, bulb falling off, etc. It is not suitable for patients with scars or upper respiratory tract lesions such as tumors and trauma, and the effect is better if a darker environment is needed. More importantly, traditional endotracheal intubation, after being inserted into the trachea, guides items such as light sticks to exit, and the position of the intubation can no longer be accurately located from the body surface. , may be a life-threatening adverse event.

Problems solved by technology

[0002] The traditional light rod or light cable guided tracheal intubation often has unsatisfactory brightness, curvature or inaccuracy due to structural and material defects, and may have thermal damage, bulb falling off, etc. It is not suitable for patients with scars or upper respiratory tract lesions such as tumors and trauma, and the effect is better if a darker environment is needed

More importantly, traditional endotracheal intubation, after being inserted into the trachea, guides items such as light sticks to exit, and the position of the intubation can no longer be accurately located from the body surface. , a potentially life-threatening adverse event

At present, there is no easy and quick method to check the position of the intubation tube. Generally, the following methods are adopted: 1. Observing and comparing the scale of the intubation tube at the incisors, but this method is often inaccurate, and the scale may not change significantly due to bending of the pipeline, etc., but the position of the intubation tube has changed Move, and may be affected by intubation tape, etc. Observation

2 lines of X-ray film examination and positioning, but this method (1) takes time to wait, which may delay the development of the disease, (2) the X-ray-opaque positioning line of the tracheal intubation is a longitudinal line along the tube wall, often in line with the heart and chest The longitudinal X-ray positioning lines on the mediastinum drainage tube that need to be placed due to routine postoperative surgery or other circumstances overlap and are confused. The position of the tube deviates and it is difficult for medical staff to identify it, which may even cause serious adverse situations such as endotracheal intubation or drainage tube detachment, atelectasis on one side of the lung entering too deep one-lung ventilation, etc.
