Abstract:

A hand-held aspirating device comprising a main housing having a handle and a barrel, said barrel having a front end and a rear portion, said handle having a lower end and an upper end communicating with said rear portion of said barrel; actuating means extending from said main housing beneath said barrel, means operatively associated with said actuating means to normally maintain said actuating means in an extended position, said actuating means being actuable in a direction generally parallel to said barrel to move said actuating means rearwardly toward said handle; suction means including a suction chamber disposed within said housing and responsive to the actuation of said actuating means for creating a suction within said suction chamber; a container means for receiving aspirate, said container means being removably connected to said handle; a first conduit within said housing, said first conduit having two ends, one of said ends normally being in fluid-flow communication with said container means and the other end being connected to said suction chamber; a second conduit depending from said front end of said barrel and projecting outwardly therefrom, said second conduit having two ends, one for inserting into a body cavity, the other one end being in fluid-flow communication with said container means; whereby when said actuating means is actuated and said suction is created within said suction chamber, said suction is communicated through said first conduit from said suction chamber to said container means and then through said second conduit to said one of said two ends of said second conduit thereby to aspirate fluids from said body cavity through said second conduit into said container means.
