Abstract

Medico-surgical suction systems capable not only of aspiration of body fluids from patients, but also precise collection of mucus samples, all under controlled vacuum conditions, include, as separate units, a fingertip-operated vacuum controller and liquid-sampling unit. The vacuum controller provides accurate regulation of suction during aspiration while isolating the operator'"'"''"'"'s control finger from the suctioned fluid stream.

Claims

1. A medicosurgical suction system vacuum controller comprising a longitudinally extending body, a tapered male connector member extending axially from one end of said body, a first opening at the end of said connector member, a second opening and a third opening, in the end of said body opposite to said connector member, a first bore extending axially a substantial distance within said body from said second opening, the end of said body defining said second opening Being substantially perpendicular to the axis of said first bore, a second bore parallel to and separate from said first bore extending axially within said body from said third opening, the end of said body defining said third opening being at an acute angle to the axis of said second bore, and a third bore extending axially within said connector member from said first opening, said first, second and third bores being interconnected with one another within said body by a cavity positioned in the body substantially closer to said first opening than to said second and third openings.

2. A vacuum controller as claimed in claim 1 wherein said second opening is fixed to the proximal end of a catheter for fluid flow from the catheter into said first bore.

3. A mediocosurgical suction system which comprises a suction catheter, a connector tube separate from said catheter adapted to join said system to a vacuum source and a vacuum controller connecting said catheter to said connector tube, said controller comprising a longitudinally extending body, a tapered male connector member extending axially from one end of said body, a first opening at the end of said connector member, a second opening and a third opening in the end of said body opposite to said connector member, a first bore extending axially a substantial distance within said body from said second opening, the end of said body defining said second opening being substantially perpendicular to the axis of said first bore, a second bore parallel to and separate from said first bore extending axially within said body from said third opening, the end of said body defining said third opening being at an acute angle to the axis of said second bore, and a third bore extending axially within said connector member from said first opening, said first, second and third bores being interconnected with one another within said body by a cavity positioned in the body substantially closer to said first opening than to said second and third openings.

4. A suction system as claimed in claim 3 wherein said connector tube is joined to said first opening and said catheter is joined to said second opening.
