Abstract
Apparatus including a series of kits containing apparatus for use in the placement of specific transtracheal catheters for varying periods, including a transtracheal catheter suitable for in-dwelling long-term oxygen supplementation therapy for patients with chronic obstructive pulmonary disease, by its size, perforation location and cleanability, and a method for placement.
Claims21
An apparatus for supplying oxygen to supplement the ventilation of a patient without interfering with the normal breathing of said patient, said apparatus comprising:
- a transtracheal catheter for insertion into the trachea of the patient, said transtracheal catheter including:
- an elongated flexible tube formed of a biocompatible material having a proximate end and a distal end;
- connection means affixed to the proximate end of said tube connecting said tube to an oxygen supply for providing oxygen into said tube;
- and
- said tube including:
- an inside diameter between 1.7 and 2.5 millimeters to provide oxygen through said tube with an outside diameter substantially less than the cross-sectional area of the patient's trachea so not to interfere with spontaneous breathing of the patient;
- a length sufficient to locate the proximate end of said tube external to the neck of the patient and to locate the distal end of said tube through a surgically formed opening in the trachea of said patient to an area above and adjacent the carina of the patient;
- an opening formed in said distal end of said tube to disperse oxygen into the lungs of said patient without interfering with the normal breathing of said patient, and
- a tube wall structure and thickness such as to enable flexible insertion of said tube into said trachea of said patient while resisting deformation of said tube.

- connection means affixed to the proximate end of said tube connecting said tube to an oxygen supply for providing oxygen into said tube;
- and
- said tube including:
- an outside diameter in the range of 2.1 millimeters and 3.0 millimeters to be substantially less than the cross-sectional area of the patient's trachea so not to interfere with spontaneous breathing of the patient;
- a length sufficient to locate the proximate end of said tube external to the neck of the patient and to locate the distal end of said tube through a surgically formed opening in the trachea of said patient to an area above and adjacent the carina of the patient;
- an opening formed in said distal end of said tube to disperse oxygen into the lungs of said patient without interfering with the normal breathing of said patient, and

- an inside diameter sufficient to provide oxygen through said tube at flow rates greater than two liters per minute while maintaining a back pressure of less than approximately two psi;
- a length sufficient to locate the proximate end of said tube external to the neck of the patient and to locate the distal end of said tube through a surgically formed opening in the trachea of said patient to an area above and adjacent the carina of the patient;
