Description

Light guide device for judging position of tracheal catheter

Technical Field

The utility model relates to a endotracheal tube fixes a position appurtenance field, especially relates to a judge endotracheal tube position light guide.

Background

The oral endotracheal intubation is widely applied to emergency treatment and subsequent treatment of critical illness as an emergency treatment technology, the catheter can ensure ventilation in an airway, but if the position of the catheter is improper, the catheter possibly enters a bronchus too deeply, so that single lung ventilation is caused abnormally, and hypoxia chamber is caused or bronchospasm is induced; too shallow a slide out of the trachea with fatal consequences. The oral tracheal intubation depth directly given in clinical anesthesiology is: the average adult female is 21cm, the adult male is 23cm, and the comparison is general. In reality, the individual difference of adult patients is large. Thus, a uniform cannula depth standard is clearly not appropriate. The methods for clinically determining the tracheal intubation depth generally include doctor empirical determination, auscultation of double-lung breathing sounds, X-ray chest radiography, confirmation of a fibrobronchoscope and the like, and researches show that the methods such as doctor empirical determination, X-ray chest radiography, auscultation of breathing sounds and the like are greatly influenced by the experience and subjectivity of clinicians, but the best method is a bronchofiberscope examination confirmation method, but all hospitals and departments do not have bronchofiberscope examination conditions. Therefore, the trachea cannula lacks a reliable and objective individualized depth standard, and how to judge the individualized cannula depth is worth discussing.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a judge endotracheal tube position light guide adopts the luminous guide of optic fibre, and whole positioning process is very simple effective to the cost is cheaper, and it is more convenient to use, solves because endotracheal tube puts into the medical risk that the dark is crossed shallowly and is aroused.
