    摘要: A saliva ejector (20) having a hollow tube including a cylindrical wall (27), a first end (21) for placement within an oral cavity, and a second end (22) for attachment to a suction hose. A flowpath (30) is defined within the tube (20). The ejector (20) includes a first corrugated portion (23) defined in the cylindrical wall (27), a second corrugated portion (24) defined in the cylindrical wall (27), and a filter element (26) secured across the flowpath (30). The bending qualities of the first corrugated portion (23) differ from the bending qualities of the second corrugated portion (24), thus allowing for a wide variety of bendable configurations.

    摘要: A process for the manufacture of hermetically sealed filter units and a product made thereby. The process comprises aligning a porous filter element (12) between two housing parts (14,16) and a thermoplastic skirt (24) that overlaps the edge of at least one housing part to shield the edge (28) of the filter element (12) disposed adjacent to the skirt (24), pressing the housing parts (14,16) together and then injection molding a thermoplastic overmold band (18) around the outer portions of the housing parts (14,16) to form a hermetic seal at the edge (28) of the filter element (12).
