Abstract A silicon double body cavity drain tube having a double tubular structure at one end. A silicon rubber outer tube having one end sealed and the other end open is providedaround a silicon rubber inner tube that is shorter than the outer tube. One end of the inner tube is fixed to the inner wall of the sealed end of the outer tube and the other end of the inner tube is open and may or may not be fixed to the inner wall of the outer tube. Also, the outer tube and the inner tube, respectively, have a plurality of holes passing through their respective sidewalls, the holes through the outer tube sidewall being positioned in such a manner so that they do not align with the holes in the sidewall of the inner tube.
A double body cavity drain tube comprising: an outer tube having one end closed and one end open, said outer tube having a plurality of openings therethrough; and an inner tube shorter than said outer tube positioned within said outer tube and one end of said inner tube being connected to the inner wall of said outer tube at said closed end thereof, said inner tube further having a plurality of openings therethrough along a substantial portion of the length thereof, all of said openings in said inner tube being out of alignment with said openings in said outer tube.
