Fluid removal device
A fluid removal device is provided for removing fluid from pleural space that includes a flexible, open tube with a slight resting curve. A first channel along a greater curvature of the tube contains a plurality of cannulas that can be extended into the pleural space to infuse medications. A second channel along a lesser curvature of the tube contains a line attached to the outer portion of the tube and tension placed on the line will increase the curve of the tube to assist in the placement of the tip of the tube in a desired location in the pleural space. The tube may be connected to a portable suction/fusion device via a click connect device. The tube may also include an improved tip and a tab for extending the cannulas maintains the corridor of stability.
1. A fluid removal system comprising:
a tube with a proximal end and a distal end, wherein the tube has a resting curve and is open on the proximal end and the distal end and includes a plurality of holes near the distal end;
a first channel along a greater curvature of the resting curve of the tube containing a plurality of cannulas with proximal ends and distal ends, wherein the distal ends of the plurality of cannulas can be extended beyond the first channel at the distal end of the tube;
a second channel along a lesser curvature of the resting curve of the tube containing a pull line with a distal end and a proximal end, wherein the distal end of the line is attached to the tube near the distal end of the tube and wherein a force applied to the pull line in a proximal direction causes the curve of the tube to reversibly increase; and
a locking mechanism attached to the tube, the locking mechanism securing the pull line in place such that, when tension is placed on the pull line such that the curve of the tube is increased and the pull line is secured in the locking mechanism, the increased curve of the tube is maintained,
wherein the locking mechanism includes a gripping device on the proximal end of the pull line, a plurality of evenly spaced beads attached to the pull line, and a V-lock attached to the tube, the V-lock designed and configured to prevent a selected one of the plurality of beads placed in the V-lock from moving distally when tension is on the pull line.
2. A fluid removal system comprising:
a tube with a proximal end and a distal end, wherein the tube has a resting curve and is open on the proximal end and the distal end and includes a plurality of holes near the distal end;
a first channel along a greater curvature of the resting curve of the tube containing a plurality of cannulas with proximal ends and distal ends, wherein the distal ends of the plurality of cannulas can be extended beyond the first channel at the distal end of the tube;
a second channel along a lesser curvature of the resting curve of the tube containing a pull line with a distal end and a proximal end, wherein the distal end of the line is attached to the tube near the distal end of the tube and wherein a force applied to the pull line in a proximal direction causes the curve of the tube to reversibly increase; and
a locking mechanism attached to the tube, the locking mechanism securing the pull line in place such that, when tension is placed on the pull line such that the curve of the tube is increased and the pull line is secured in the locking mechanism, the increased curve of the tube is maintained,
wherein the locking mechanism includes a handle on the tube, a gripping device attached to the proximal end of the pull line, a plurality of evenly spaced beads attached to the pull line, and a groove in the handle, wherein the groove includes a plurality of evenly spaced divots, each divot designed and configured to accept a one of the plurality of beads, wherein placement of at least a portion of the plurality of beads in a respective ones of the plurality of divots prevents the portion of the plurality of divots from moving distally when tension is on the pull line.
