Improvement introduced in orotracheal cannula with a double lumen.

摘要

This is orotracheal cannula (10) with double lumen, and a lumen (LI) and left right lumen (12) for respectively.Allow entry and exit of air during inspiration and expiration or insertion of orotracheal tube for rescue and insertion of the probe endoscopic / transesophageal echo / fiberscope; cannula (10) is confeCcionada suitable polymer or other material, formed by a single piece (20) with anatomical forms especially obtained by the association of dimensional (x), (y), (XL), (YL), (x2), (W) and (c)Which are in one piece (20) and width (x) and height (y) of quadrangular frame (21) that composes the frontal portion which, in turn,It is provided for opening the main (22) with a width (XL) and height (YL) where develops a rectilinear peripheral wall (23) followed by reduction of width (x2) and the step (d).Consequently, protector of the bite (PM).And said peripheral wall (23) follows a rectilinear length (W); the lumens (LI) and (L2) are formed by providing a partition wall (24) formed by a short appendix (24a) s.And develops from the central portion of the upper edge opening (22).With that said appendix (24a) moves orthogonally to pierce the wall peripheral rectilinear (23) in curvature (c) together with the extension of the right lateral portion (23a) and channel.Cross section I reflected so as to compose a lateral opening (an EB - 1) and lower (AB2); cannula (10), provides,One input channel for monitoring carbon dioxide - CO2 formed by the orifice (25) practiced and superimposed over the appendix (24a).Since the birth of the orifice (25) follows tubularmente to accompany the rectilinear portion (W) and curvature (c).
