Abstract

A disposable oral suction tip includes a tubular body having a suction line attachment end, a mouthpiece end, an exterior surface and at least one central passage that extends between the suction line attachment end and the mouthpiece end. A mouthpiece is secured to the mouthpiece end of the tubular body. At least one vacuum release channel is provided having a first end and a second end. The at least one vacuum release channel extends along the exterior surface of the tubular body. The first end of the at least one vacuum release channel is positioned to be placed into a patient'"'"'s mouth along with the mouthpiece. The second end is spaced from the mouthpiece such that the at least one vacuum release channel provides direct venting of the oral cavity.

Claims

1. A disposable oral suction tip, comprising:

a bendable tubular body having a consistent cross-sectional profile having a suction line attachment and attachable to a suction source, a mouthpiece end, an exterior surface and at least one central passage that extends between the suction line attachment end and the mouthpiece end;

a mouthpiece secured to the mouthpiece end of the tubular body where the mouthpiece is directly open to a plurality of vacuum release channels and the mouthpiece is directly open to the at least one central passage so that the plurality of vacuum release channels and the at least one central passage can communicate; and

a tubular barrel having an internal surface with a plurality of internal vanes overlies the tubular body, the internal vanes dividing a space between the internal surface of the tubular barrel and the exterior surface of the tubular body into the plurality of vacuum release channels each of the plurality of vacuum release channels having a first end and a second end, each of the plurality of vacuum release channels extending along the exterior surface of the tubular body, the first end being positioned for placement in a patient'"'"'s mouth along with the mouthpiece and the second end being spaced from the mouthpiece such that there is communication between the suction source and each of the plurality of vacuum release channels, so that when the patient'"'"'s mouth is closed over the mouthpiece the plurality of vacuum release channels provide direct unobstructed venting of the oral cavity to prevent backflow from the at least one central passage into the patient'"'"'s mouth and there is no effect on the force of suction up the at least one central passage.

2. A disposable oral suction tip, comprising:

a bendable tubular body having a suction line attachment end, a mouthpiece end, an exterior surface and at least one central passage that extends between the suction line attachment end and the mouthpiece end;

a mouthpiece secured to the mouthpiece end of the tubular body; and

a tubular barrel having an internal surface with a plurality of internal vanes overlies the tubular body, the internal vanes dividing a space between the internal space of the tubular barrel and the exterior surface of the tubular body into a plurality of the vacuum release channels each of the plurality of vacuum release channels having a first end and a second end, each of the plurality of vacuum release channels extending alone the exterior surface of the tubular body, the first end being positioned for placement in a patient'"'"'s mouth along with the mouthpiece and the second end being spaced from the mouthpiece such that each of the plurality of vacuum release channels provides direct venting of the oral cavity surface to resist removal of the tubular barrel from over the tubular body.

3. The disposable oral suction tip as defined in claim 2, wherein the tubular barrel has an end that is integrally formed into the mouthpiece.

4. A disposable oral suction tip, comprising:

a bendable tubular body having a suction line attachment end, a mouthpiece end, an exterior surface and at least one central passage that extends between the suction line attachment end and the mouthpiece end; and

a tubular barrel having an internal surface with a plurality of internal vanes overlying the tubular body, the internal vanes dividing a space between the internal surface of the tubular barrel the exterior surface of the tubular body into a plurality of vacuum release channels extending along the exterior surface of the tubular body, each of the vacuum release channels having a first end and a second end, the first end communicating with the mouthpiece end of the tubular body and the second end being spaced from the mouthpiece end of the tubular body such that the vacuum release channels provide direct venting of the oral cavity, the tubular barrel having a mouthpiece end that is integrally formed into a mouthpiece, the internal vanes having peripheral edges that form a saw tooth gripping surface, the saw tooth gripping surface allowing the tubular barrel to be slid over the tubular body in a first direction, and digging into the exterior surface of the tubular body to resist removal of the tubular barrel from over the tubular body in a second direction.
