Abstract
A breather bag (10) is adapted for use with a breathing circuit (12). The exterior surface (38) of the bag (10) is roughened and substantially non-uniform for ease of gripping by an anesthesist (18). When the gloves (33) of the anesthesist (18) are wet, the gloves (33) tend to cause slippage when attempting to squeeze a bag as known in the prior art. Due to the present invention, the roughened exterior surface (38) greatly reduces this likelihood of slippage. A relatively small exterior portion (40) is substantially smooth as is the interior surface (46).
