Patent ID: 7066903

Claim:
A sleeve and aspirator tip combination comprising: a. an elongated aspirator tip comprising (i) a neck comprising an internal channel with at least one orifice located near the distal end of the neck into which gases, fluid, and material may flow; (ii) an elongate tip coupling section defining an internal channel; and (iii) at least one longitudinal groove extending along the exterior of the tip coupling section; (iv) wherein the neck is connected at its proximal end to the distal end of the tip coupling section and the internal channel of the tip coupling section is in communication with the internal channel in the neck allowing gases, fluid, and material flowing through the internal channel in the neck to flow into the internal channel in the tip coupling section; and (v) the at least one longitudinal groove extending along the tip coupling section from substantially the distal end of the tip coupling section to substantially the proximal end of the tip coupling section; and b. a tapered elongated sleeve comprising (i) a sleeve coupling section comprising a generally tubular wall that defines an internal receiving volume; and (ii) a plurality of orifices spaced from the sleeve coupling section arranged along the sleeve to provide communication between the external environment and the interior of the sleeve; c. wherein the aspirator tip is coupled to the sleeve by inserting the tip coupling section into the receiving volume of the sleeve coupling section to form a coupled region; and d. at least one venting channel is formed between the portion of the at least one longitudinal groove extending along the exterior of the tip coupling section and the tubular wall of the sleeve coupling section allowing communication between the external environment and the interior of the sleeve.
