Abstract:
A vacuum dosing device comprising of:(a) a cylindrical tube encompassed by a cylindrical section case, said tube extending proximally and distally through said case, forming conical shaped ends, at least two first openings, said first openings located on either end of tube prior to the conical shaped ends, said first openings being diametrically opposite one another; said proximal conical shaped end of said tube having a vacuum source, proximal to said vacuum source and distal to said distal first openings; a semicylindrical shaped deflector extending from the proximal end of said tube to the distal end of said tube; (b) said tube having an outer and inner wall; a rubber cylindrical tube within the cylindrical section case; (c) said case having a top and bottom semicylindrical section, each semicylindrical section having an inner and outer wall, said semicylindrical sections providing a clearance between the outer wall of said tube and the inner wall of said case; each of said top and bottom semicylindrical sections having a left and right lid on either end thereof, said lids connecting together to form the case; said connected lids having openings on either side, said opening having an inner and outer edge, said inner edge of said semicylindrical openings forming holding straps around said rubber tube; a second opening located adjacent to said left lid of said top semicylindrical section of said case, a third opening located above the deflector, said third opening having a diameter equal to that of the first openings in the tube; a thin tube originating at the second opening adjacent to the left lid and running horizontal from the left lid to the right lid then vertically through the right lid to the third opening; (d) a valve box located above said semicylindrical section of said case and adjacent the left lid, said valve box having a lever opening to said vacuum source; said valve box having a first section located on the base, and two planes, one top central plane and another coaxial with the latter, determining a gutter surrounding the top central plane, a fourth opening in the center of said gutter connecting said valve box with the vacuum source; a second section, comprising a cavity located in the forward part of the first section communicating with the inside of the case, through a fifth opening in the case; (e) said gutter having a ring, with a rod perpendicular to said ring at one end thereof; a valve lid extending parallel to said ring; said valve lid having a fourth opening, said rod extending through said opening for the free displacement of the rod in a reciprocal vertical movement; wherein said reciprocal motion of said rod results in a vacuum in said case causing an expansion of said cylindrical tube, allowing passage of air or aspirated material between said first holes.
