Reduced internal volume neonatal suction adaptor

An adaptor for use in a neonatal ventilation circuit, said adaptor comprising:

• a central housing disposed about and substantially defining a central chamber, said central chamber having a volume no greater than about one cubic centimeter;
• an endotracheal connector secured to and extending from said central housing, said endotracheal connector comprising a sleeve disposed about a core, said sleeve being separated from said core to thereby substantially define an annular recess, said core having a core passage which is in fluid communication with said central chamber;
• a suction access tube secured to and extending from said central housing, said suction access tube having a suction access passage which is in fluid communication with said central chamber said suction access tube having means for removably securing a suction tube to said suction access tube while allowing passage of a suction catheter through said suction tube and at the same time substantially reducing the deadspace produced by said connection;
• and
• a ventilation connector secured to and extending from said central housing, said ventilation connector comprising a tube having a ventilation passage which is in fluid communication with said central chamber, said ventilation connection further having means for removably securing a ventilator while at the same time substantially reducing the deadspace produced by said connection.

An adaptor for use in a neonatal ventilation circuit, said adaptor comprising:

• a central housing disposed about and substantially defining a central chamber, said central chamber having a volume in the range from about 0.4 cubic centimeters to about 0.6 cubic centimeters;
• an endotracheal connector secured to and extending from said central housing, said endotracheal connector comprising a sleeve disposed about a core, said sleeve being separated from said core to thereby substantially define an annular recess, said core having a core passage which is in fluid communication with said central chamber;
• a suction access tube secured to and extending from said central housing, said suction access tube having a suction access passage which is in fluid communication with said central chamber and which is substantially parallel to said core passage of said endotracheal connector;
• a ventilation connector secured to and extending from said central housing, said ventilation connector comprising a tube having a ventilation passage which is in fluid communication with said central chamber;
• said adaptor configured such that deadspace within the central chamber is maintained at a predetermined volume in the range of from about 0.4 cubic centimeters to about 1.0 cubic centimeters.
