Abstract
A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise at least two pressure relief valves that open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.
Claims9
A method comprising:
- providing an endotracheal (ET) tube cap that comprises:
- a tubular housing defined by a cylindrical wall that extends between a first end and a second end, wherein a closed top surface covers the first end,
- an ET tube receiving aperture at the second end is configured to receive an ET tube,
- the cylindrical wall defining a cylinder interior surface and a cylinder exterior surface, the cylindrical wall further defining a cylinder interior volume bounded by the cylinder interior surface from the first end to the second end,
- the closed top surface permanently blocking all access to the interior volume from the first end,
- wherein access points to the interior volume through the cylindrical wall consist of a first element, a second element and a third element, all of which extend from the cylinder exterior surface,
- wherein the first element is an intake tube comprising an unobstructed passageway between a proximal tube end and a distal tube end;
- and
- the second element is a first pressure relief valve and the third element is a second pressure relief valve, the first and the second pressure relief valves are configured to open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold;
- inserting the ET tube into the ET tube receiving aperture;
- flowing oxygen through the ET tube from an oxygen source connected to the intake tube;
- intubating a patient while the oxygen is flowing through the ET tube;
- and
- replacing the ET tube cap with a ventilator connector that connects the ET tube to a ventilator.

A method comprising:
- providing an endotracheal (ET) tube cap that comprises:
- a housing extending from a top end to bottom end where an ET tube receiving aperture is located, the ET tube receiving aperture is configured to receive an ET tube,
- a closed surface covers the top end,
- the housing is tubular and defines an interior surface and an exterior surface, the housing further defining an interior volume bounded by the interior surface from the top end to the bottom end,
- wherein access points to the interior volume through the housing consist of a first pressure relief valve, a second pressure relief valve, the ET tube receiving aperture and an intake tube,
- the intake tube extends from the exterior surface and comprises an unobstructed passageway between a proximal tube end and a distal tube end;
- and
- wherein the first and the second pressure relief valves are configured to open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold;
- inserting an ET tube into the ET tube receiving aperture;
- flowing oxygen through the ET tube from an oxygen source connected to the intake tube;
- intubating a patient while the oxygen is flowing through the ET tube;
- and
- replacing the ET tube cap with a ventilator cap that connects the ET tube to a ventilator.
10 more elements
An endotracheal (ET) tube arrangement comprising:
- an ET tube;
- an ET tube cap for connecting the ET tube to a pressurized oxygen source, wherein the pressurized oxygen source is configured to flow oxygen through the ET tube cap and out from a distal end of the ET tube;
- a ventilator cap for replacing the ET tube cap on the ET tube for alternatively connecting the ET tube to a ventilator;
- the ET tube cap comprising:
- a housing that extends from a first end to a second end comprising an ET tube receiving aperture that is configured to receive the ET tube,
- the housing defining an interior surface and an exterior surface, the housing further defining an interior volume bounded by the cylinder interior surface from the first end to the second end,
- wherein access points of the housing consists of four access points to the interior volume through the housing, the four access points consist of a first pressure relief valve, a second pressure relief valve, the ET tube receiving aperture and an intake tube that extends from the exterior surface, and
- wherein the intake tube comprises an unobstructed passageway between a proximal tube end and a distal tube end.
