Abstract

Abstract This invention pertains to a suction guide for endotracheal intubation stylet having a first portion made of substantially rigid material having a tubular shape with a plurality of openings for suctioning unwanted fluids therethrough, a second portion integral with and immediately adjacent to the first portion, being made of a semi-rigid material, said second portion having a tubular shape and a sufficient length to be bent and inserted into a human body cavity, and a third portion integral with and immediately adjacent to the second portion, being made of a flexible material having a tubular shape and of a sufficient length to extend from a body after insertion with an open end adapted for connection to a suction source. The second portion is semi-rigid and is inserted into the tracheal passage through the throat of the patient and acts as a guide for subsequent insertion of an endotracheal tube over the stylet.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 250 words
A suction stylet guide adapted to be connected to a suction source for endotracheal intubation of a patient, comprising: a first portion made of a substantially rigid material having a round tubular shape terminating in a tip with a plurality of openings for permitting suction of unwanted fluids therethrough, said first portion being from about one-quarter to one inch in length; a second portion unitary and coaxial with the first portion, said second portion being made of a semi-rigid bendable memory material which will permit shaping to and maintaining of a curvature approximately the curvature of the oropharynx of the patient, said second portion having a round tubular shape and being from about 3-6 inches in length permitting insertion into the patient so as to submerge said first portion into unwanted fluids to be suctioned, said second portion being adapted to receive a round endotracheal tube sleeved thereover permitting positioning of the tube within the patient; a third portion unitary and coaxial with the second portion, said third portion being made of a flexible material, said third portion having a round tubular shape, an open end adapted for connection to the suction source, and being from about six inches to five feet in length; said first, second and third portions being sized to allow sleeving of the endotracheal tube over the suction stylet guide; and said open end of the third portion adapted to receive a detachable suction port means that is handoperated and non-integral with said suction stylet guide.
