Abstract
Wound drainage system having a wound drainage catheter with an apertured distal end and a closed reservoir system. A plug in the lumen of the distal end substantially engages the lumen. A thread connects the plug to a pulling mechanism external the closed reservoir system for pulling the thread to move the plug toward the suction end of the catheter to sterilely clear the lumen. The plug may have an aperture so that multiple plugs may be positioned in the lumen, with each plug thread passing through the aperture of each upstream plug. Each plug may be separately pulled through the lumen to clear catheter of occluded material.
Claims25
A wound drainage system comprising:
- a wound drainage catheter having a lumen, an apertured distal end such that material to be drained may enter the lumen therethrough and a suction end,
- a closed reservoir system,
- the suction end of the catheter being sealably connected to the closed reservoir system such that material may drain from the distal end of the catheter into the closed reservoir,
- a plug in the lumen of the distal end of the catheter, the plug having a diameter to substantially engage the circumference of the lumen,
- a thread having one end connected to the plug, and
- pulling means external the closed reservoir system for pulling the thread to move the plug toward the suction end of the catheter to sterilely clear the lumen.
A wound drainage system comprising:
- a wound drainage catheter having a lumen, an apertured distal end such that material to be drained may enter the lumen therethrough and a second end,
- first and second plugs in the lumen of the distal end of the catheter, the first plug having an aperture therethrough, each plug having a thread attached thereto,
- the thread attached to the second plug passing through an aperture of the first plug,
- such that the first plug may be pulled toward the suction end of the lumen to clear the lumen without causing the second plug to move, and such that the second plug may be later pulled toward the suction end of the lumen to clear the lumen.
A method for sterilely clearing a wound drainage catheter, the catheter having an apertured distal end, a lumen and a vacuum end comprising:
- providing a first plug in the lumen of the distal end of the catheter, the first plug having a diameter to substantially engage the circumference of the lumen, the first plug having a first thread attached thereto traveling through the lumen,
- placing the vacuum end of the catheter in communication with a closed reservoir,
- sterilely pulling the first thread to thereby move the first plug toward the suction end of the catheter without breaching the closed reservoir.
