Abstract:     A disposable mask and suction catheter includes a mask having a front side and a back side, the back side being disposed in contact with a user's face during use. The disposable mask and suction catheter also includes a catheter tube having a first and a second end, the first end being removably attachable to a suction source for removing exhaled air and the second end being attached to the back side of the mask. The disposable mask and suction catheter helps to prevent fogging of glasses or other eyewear due to moist, exhaled air that escapes from behind the mask, and improves user comfort by constantly removing the warm, moist air behind and around the mask and drawing cool, dry air into the mask.

First Claim:
Show all 27 claims		 What is claimed is:     1. A disposable mask and suction catheter for preventing fogging of a user's glasses and providing desired cooling, comprising: a disposable pervious mask having a front side and a back side, the back side being disposed in contact with a user's face during use and allowing a user to breathe through the mask during an operation; and
  • a length of relatively inexpensive lightweight suction catheter tubing having a first and a second end, the first end adapted to be connected to an available hospital operating room suction source for removing exhaled air, and the second end being in communication with the back side of the mask to receive exhaled air from a user, the catheter being of sufficient diameter to remove enough air to prevent fogging of a user's glasses and to provide increased comfort by drawing cool, dry air into the mask.
