Abstract
The present invention provides an apparatus and a method for administering medicants, specifically anesthesia, to a catheterized patient. An administration tube is provided in longitudinal connection with an aspiration tube. The administration tube preferably has plural fenestrations provided along its length to administer anesthesia to the areas surrounding the catheter. The aspiration tube has at least one opening to aspire fluids from a patient. A preferred usage is for the interpleural space, wherein fluids are aspired through a series of aspiration apertures on the aspiration tube, and the surrounding tissues and intercostal nerves are anesthetized through the fenestrations to alleviate pain and discomfort commonly associated with catheters.
Claims24
A multiple lumen thoracostomy catheter comprises an aspiration tube with a tube wall and a proximal and a distal end for aspiring fluids from a patient from the distal end to the proximal end, an anesthetic administration tube generally of a same length as the aspiration tube being longitudinally connected to the aspiration tube wall and having a proximal end for connection to an anesthetic source for simultaneously administering anesthetic during insertion of the catheter, and a distal end for administering anesthetic to a patient along the tube wall, the connected tubes together forming a catheter having a distal insertion end and a proximal connection end, plural anesthetic administration fenestrations provided on the anesthetic administration tube along the aspiration tube wall, near the distal insertion end, and multiple aspiration apertures provided on the aspiration tube proximal the insertion end.
An interpleural aspiration catheter apparatus comprising a first aspiration tube having a large bore longitudinally connected to a second anesthetic tube having a smaller bore, both tubes being constructed of a material suitable for catheter functions for insertion into an interpleural cavity of a patient, the first tube having an insertion end with plural aspiration openings, and having an opposite connection end for connection with aspiration means, the second tube having an insertion end with proximal plural anesthetic fenestrations extending along the first tube and communicable with the patient for administering anesthetic along a length of the catheter proximal the insertion end while inserting the catheter into the interpleural cavity.
A method for administering medicants to a catheterized patient comprising providing an interpleural aspiration catheter having an administration tube in longitudinal connection to an aspiration tube, providing longitudinally spaced medicant release fenestrations in the administration tube, supplying medicants to the administration tube and releasing medicants through the fenestrations along a length of the administration tube which is connected to the aspiration tube.
