Patent ID: 8281785

Claim:
Breathing equipment ( 10 ) at least employable for use in anesthesiology procedure comprising: a regularly shaped breathing bag ( 12 ) of which its location of discharging of exhaled gas ( 12 . 2 ) is situated remote from its location ( 12 . 1 ) via which it is indirectly connectable to a patient and which is accordingly of a suitably flexible material to at least enable manually assisting in the breathing process of such patient during use of the equipment ( 10 ) in response to its manual compression and relaxation; a gas-guiding conduit ( 16 , 34 , 40 ) extending between a breathing piece ( 28 ) via which gas is inhaled and exhaled by a patient during use of the equipment and the location ( 12 . 1 ) of the breathing bag ( 12 ); a supply conduit ( 24 ) via which inhalation gas in the form of air or oxygen and, where applicable, agent is introduced for inhalation by such patient via the breathing piece ( 28 ) and of which supply conduit ( 24 ) part extends within at least part of gas guiding conduit ( 16 , 34 , 40 ) towards said breathing piece ( 28 ) while its discharge end ( 26 ) is located in substantial proximity of the breathing location of a person on whom said equipment is used, thereby making inhalation gas directly available once the equipment is so in use; a gas removal conduit ( 20 ) via which exhaled gas is discharged and said supply conduit ( 24 ) and part of the gas removal conduit ( 20 ) run along a common central line ( 23 ) and, within the gas guiding conduit ( 16 , 34 , 40 ) at least in part; characterized in that the gas removal conduit ( 20 ) returning in snug adjacent relationship with the breathing bag ( 12 ) from its location of discharging of exhaled gas ( 12 . 2 ) to the vicinity of the location ( 12 . 1 ) via which it is indirectly connectable to a patient in a way that maintains proper access to the manual manipulation of the bag ( 12 ) while extending to branch laterally from the gas guiding conduit ( 16 , 34 , 40 ) at a location remote from the breathing piece ( 28 ) and at least providing for being couplable to extend to a location of final discharging displaced from the location of use of the equipment ( 10 ) to limit the possibility of exhaled gas contamination of its zone of use; and in that at least part of the supply conduit ( 24 ), as appropriately couplable at its supply end, laterally meets the gas guiding conduit ( 16 , 34 , 40 ) also at a location remote from the breathing piece ( 28 ) thereby in conjunction with the conduit ( 20 ) contributing to facilitation of the use of the equipment ( 10 ) thereby limiting interference with a manual bag manipulation action once the equipment is in operative use.
