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

An assembly comprising a medical attachment device, and a connector for connecting at least one fluid source to the attachment device;

• wherein 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;
• wherein each of the at least two positive pressure fluid inlet ports is connectable to a respective fluid source;
• wherein each of the at least two positive pressure fluid inlet ports is in fluid communication with the fluid outlet port;
• wherein each of the at least two positive pressure fluid inlet ports comprises an attachment device mechanism for selectively starting and stopping a flow of fluid from the respective fluid source to the fluid outlet port;
• and
• 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 a respective one of the at least two positive pressure fluid inlet ports 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 respective fluid inlet port and the fluid outlet port via the fluid access port.

A method of switching one fluid source with another fluid source and maintaining continuous positive pressure fluid flow to a respirator or ventilator, comprising the steps of:

• providing the respirator or the ventilator;
• providing the one fluid source;
• attaching said one fluid source to one connector, said one connector comprising one housing and one connector mechanism for selectively starting and stopping a flow of fluid;
• providing an attachment device comprising a body having a fluid outlet port and at least two positive pressure fluid inlet ports;
• wherein each of the at least two positive pressure fluid inlet ports is connectable to a respective fluid source;
• wherein each of the at least two positive pressure fluid inlet ports is in fluid communication with the fluid outlet port;
• wherein each of the at least two positive pressure fluid inlet ports comprises an attachment device mechanism for selectively starting and stopping the flow of fluid;
• and
• wherein the attachment device mechanism comprises a valve moveable between an open valve position and a closed valve position;
• providing a pressure regulator for regulating fluid pressure and fluid flow speed;
• connecting the fluid outlet port of the attachment device to the pressure regulator;
• connecting the pressure regulator to the respirator or the ventilator;
• connecting said one connector to one fluid inlet port of the attachment device;
• selectively starting the flow of fluid from said one fluid source to the respirator or the ventilator using said one connector mechanism and said one attachment device mechanism;
• providing another fluid source;
• attaching said another fluid source to another connector, said another connector comprising another housing and another connector mechanism for selectively starting and stopping the flow of fluid;
• connecting said another connector to another fluid inlet port of the attachment device;
• selectively starting the flow of fluid from said another fluid source to the respirator or the ventilator using said another connector mechanism and another attachment device mechanism;
• selectively stopping the flow of fluid from said one fluid source to the respirator or the ventilator using said one connector mechanism and said one attachment device mechanism;
• and
• disconnecting said one connector from said one fluid inlet port of the attachment device.

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;
