Abstract
Abstract A vacuum curette including an integral reservoir supported from the outlet end of the curette. The reservoir itself is provided with a vacuum outlet to which the inlet end of a flexible vacuum hose may be connected and the interior of the reservoir includes a partition forming filter body through which the outlet end of the curette opening into the reservoir extends. Also, the base end of the curette from which the reservoir is removably supported includes a vacuum bleed or break opening between the vacuum outlet and the partition defining filter body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A vacuum curettage device comprising a curette including an elongated tubular shank having an outer tip inlet at one end and a discharge end portion at its other end, a hollow fitting having first and second opposite sides, the discharge end portion of said shank being supported from and projecting through said first side of said fitting into the latter, said second side of said fitting having a combined inlet and outlet opening formed therein with which said discharge end portion is at least generally aligned, said fitting including a vacuum air flow outlet opening adapted to be communicated with a suitable source of vacuum, a reservoir removably supported from said fitting in communication with and closing said combined inlet and outlet opening, and a filter assembly including an outer periphery sealed relative to said combined inlet and outlet opening and a central opening formed therethrough with which said discharge end portion is registered and engaged in at least reasonably good sealed engagement therewith.
