Abstract
Abstract A surgical suction device is provided for removing fluid from a wound which device is adapted to be connected to a suction pump by a hose pipe. The device includes a tubular handle and an inner tube extending from one end of said handle. The inner tube is provided with a suction opening at one end and an open tip at its other end. An outer tube surrounds the inner tube to form an annular space therebetween with the inner and outer tubes being movable relative to each other. The outer tube is telescoped over a portion of the handle and includes an aperture normally aligned with an aperture formed in the handle for controlling the suction functions. A plurality of openings is also formed in the space for quickly removing large quantities of fluid from a wound. At one end of the outer tube there is provided a tapered section having a suction opening for contacting the wound and a seat member at its other end. The open tip of the inner tube is movable into and out of contact with the seat member of the tapered section so that when they are in contact, a single tube suction function is obtained, and when they are out of contact, a sump suction function is obtained.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
208 words
A surgical suction device for removing fluid from a wound and adapted to be connected to a suction pump by a hose pipe, said device comprising: a tubular-shaped handle, an inner tube extending from one end of said handle and having a suction opening at one end thereof and a tip at the other end thereof, an outer tube surrounding said inner tube to form an annular space therebetween, said inner and outer tubes being movable relative to each other, a plurality of openings formed in said channel for quickly removing large quantities of fluid from a wound, said outer tube including at one end thereof a tapered section having a suction opening at one end and a seat member at its other end, and the tip of said inner tube being movable into and out of contact with said seat member so that when said tip and said seat member are in contact with each other, a single tube suction function is obtained in that suction is applied only to said tip, and when said tip and said seat member are out of contact with each other, a sump suction function is obtained in that suction is applied to both said plurality of openings and said tip.
Claim 2
Dependent Claim
208 words
A surgical suction device for removing fluid from a wound and adapted to be connected to a suction pump by a hose pipe, said device comprising: a tubular-shaped handle, an inner tube extending from one end of said handle and having a suction opening at one end thereof and a tip at the other end thereof, an outer tube surrounding said inner tube to form an annular space therebetween, said inner and outer tubes being movable relative to each other, a plurality of openings formed in said channel for quickly removing large quantities of fluid from a wound, said outer tube including at one end thereof a tapered section having a suction opening at one end and a seat member at its other end, and the tip of said inner tube being movable into and out of contact with said seat member so that when said tip and said seat member are in contact with each other, a single tube suction function is obtained in that suction is applied only to said tip, and when said tip and said seat member are out of contact with each other, a sump suction function is obtained in that suction is applied to both said plurality of openings and said tip.
Claim 3
Dependent Claim
44 words
