Selective attachment device with multiple fluid sources for maintaining positive fluid pressure

A medical attachment device for maintaining positive fluid pressure in a patient, the attachment device comprising a body having a fluid outlet port, at least one positive pressure fluid inlet port, and an obstructor holder comprising a fluid access port in fluid communication with the fluid outlet port;

• wherein the at least one positive pressure fluid inlet port is connectable to a first fluid source;
• wherein the at least one positive pressure fluid inlet port is in fluid communication with the fluid outlet port via the fluid access port;
• wherein the at least one positive pressure fluid inlet port comprises an attachment device mechanism for selectively starting and stopping a flow of fluid from the respective fluid source to the fluid outlet port;
• wherein the attachment device mechanism is housed at least partially in the obstructor holder and comprises:
• an arm having a first end in fluid communication with the at least one positive pressure fluid inlet port and a second end;
• an obstructor in the first end configured to seal the fluid access port in the obstructor holder;
• and
• a circular aperture in the second end to enable, by motion of the arm, selective fluid communication between the fluid inlet port and the fluid outlet port via the fluid access port.

A medical attachment device for maintaining positive fluid pressure in a patient, the attachment device comprising a body having a fluid outlet port, at least two positive pressure fluid inlet ports, and an obstructor holder comprising a fluid access port in fluid communication with the fluid outlet port;
