Filed:

Appl. No.:

08/867748

Jacques Chelly - Houston TX
Jeffrey Katz - Houston TX
Thomas Smith - Alvin TX

Assignee:

The Board of Regents of the University of Texas System - Austin TX

International Classification:

A61M 1600

US Classification:

12820026, 12820729, 12820714

Abstract:

An ET guide is provided which is preferably made of polytetrafluoroethylene (PTFE), also known as TeflonÂ. The distal end is of a reduced profile so that the guide can be left in place, with the ET removed in the operating room just prior to a tracheostomy. If for any reason problems are encountered in the tracheostomy procedure, the guide of the present invention, having been left in after the removal of the ET, can facilitate a reinsertion of the ET to avoid danger to the patient from a decrease in oxygen saturation. At the same time, the reduced distal profile allows the guide to remain in place during the tracheostomy procedure without obstructing the area of the incision for the tracheostomy. The guide can remain in place until the tracheostomy is successfully concluded, at which point it can be optionally removed. Leaving the guide in position as the tracheostomy is being conducted facilitates reinsertion of the ET which is routinely taken out in the operating room prior to the onset of the tracheostomy.

International Classification:

A61M 1600

US Classification:

12820714

Abstract:

Disclosed is an endotracheal device provided with a colorimetric carbon dioxide indicator. The device functions to indicate the proper intratracheal placement of an endotracheal tube by detecting for the presence of carbon dioxide in expired air passing through the device.

Abstract:

A balloon-tipped suction catheter, for extirpating and aspirating tracheobronchial secretions from the trachea, endotracheal tube or tracheostomy tube and a method for using such catheter. The catheter preferably embodies an elongated tube with a cannula extending along the elongated tube. The distal end of the cannula communicates with an expandable membrane or balloon which is attached either to the walls of the distal end of the elongated tube or directly to the distal end of the cannula. Proximal to the expandable membrane are apertures which provide fluid communication between the exterior and interior of the elongated tube. A control port is provided at the proximal end of the catheter to control the transmission of suction through the catheter. In use, the catheter of this invention is inserted into an endotracheal tube, for example, to remove secretions. Positive end expiratory pressure ("PEEP") can be maintained by inserting the catheter through a "Y" connector assembly with a self-sealing diaphragm assembly.
