Valve for pulmonary medical use

A valve for pulmonary treatment apparatus comprising

• a first valve portion including a body in the form of a plate having a flat bottom surface and a flat top surface,
• an input oxygen tube on said top surface and aligned with an opening in said top surface and an input suction tube on said top surface and aligned with an opening in said top surface,
• an inner suction tube and an inner oxygen tube on said bottom wall of said first valve portion,
• a first finger tab extending from said body of said first valve portion and accessible to an operator,
• a first locking member on said bottom surface of said plate of said first portion, said first locking member forming a unitary piece with said first portion,
• a second valve portion having a body in the form of a dish having a flat bottom wall and a surrounding wall, said bottom wall having a top surface and a bottom surface,
• an oxygen outlet tube and a suction outlet tube on said bottom wall of said body of said second valve portion,
• an opening in said bottom wall between said inner suction tube and said outlet suction tube,
• an opening in said bottom wall between said inner oxygen tube and said outlet oxygen tube,
• a second finger tab extending from said second portion of said valve,
• a second locking member forming a unitary piece with with said second portion of said valve, and
• said first locking member being aligned with said second locking member and secured thereto to couple said first and second portions of said valve together, said first and second locking members including means pulling said first and second portions of said valve toward each other to form a tight fit therebetween.

A valve for pulmonary treatment apparatus comprising

• a first valve portion having an outer surface and an inner surface,
• an oxygen supply tube and a suction supply tube extending from said outer surface of said first valve portion,
• a second valve portion having an outer surface and an inner surface,
• an oxygen output tube and a suction output tube extending from said outer surface of said second valve portion,
• means inside said valve between said first and second valve portions for coupling said oxygen input tube to said oxygen output tube and said suction input tube to said suction output tube,
• first locking means forming a unitary piece with with said first valve portion and extending from said inner surface thereof,
• second locking means forming a unitary piece with with said said second valve portion and extending from said inner surface thereof,
• said first locking means tightly engaging said second locking means and exerting a pulling force which causes said first and second valve portions to be pulled toward each other and tightly locked together, thus locked together, said first and second valve portions are rotatable with respect to each other between a first and a second orientation thereof.

A valve for pulmonary treatment apparatus comprising

• a first valve portion and a second valve portion tightly secured together and rotatable with respect to each and forming a generally fluid tight assembly,
• a first finger tab on said first valve portion and a second finger tab on said second valve portion, said first and second finger tabs being manipulated by an operator to rotate said first and second valve portions with respect to each other,
• said first valve portion having an inner surface and an outer surface,
• said second valve portion having an inner surface and an outer surface, said inner surface of said first valve portion and said inner surface of said second valve portion facing each other on the inside of said valve,
• a fluid supply tube and a suction supply tube extending from said outer surface of said first valve portion,
• a fluid output tube and a suction output tube extending from said outer surface of said second valve portion,
• means inside said valve for selectively and alternately coupling said fluid supply tube to said fluid output tube and said suction supply tube to said suction output tube,
• a first coupling tube extending from said inner surface of said first valve portion,
• a second coupling tube extending from said inner surface of said second valve portion toward and engaging said first coupling tube of said first valve portion,
• a spring inside said valve and having a first end and a second end, said first end of said spring engaging a portion of said first valve portion and said second end of said spring engaging a portion of said second valve portion, whereby with said finger tabs apart and said first and second valve portions in a first orientation with respect to each other, said spring is in a first state of tension and with said finger tabs squeezed together and said first and second valve portions are in a second orientation with respect to each other, said spring is under tension and tends to urge said finger tabs apart and said first and second valve portions to said first orientation,
• whereby in said first orientation of said first and second valve portions, one of said input tubes is coupled to one of said output tubes and in said second orientation, the other of said input tubes is coupled to the other of said output tubes so that in one of said orientations, oxygen is fed to a patient and in the other of said orientations, suction is fed to a patient, and
• means securely coupling together said first and second valve portions.
