Abstract
A surgical drain for draining wounds is disclosed. The drain has a tube-like body forming a lumen. The body of the drain includes a plurality of perforations therein. The drain also has a plunger for removing debris from the lumen and perforations of the drain. The plunger has a scraper, a line and a handle. The scraper of the plunger is generally located in the lumen of the body. The handle of the plunger is generally located so as to be accessible to a user. The line of the plunger generally extends through the lumen and connects the scraper and handle. The drain may have more than one plunger.
Claims7
A surgical drain for draining wounds comprising:
- an elongated tube-like body forming a lumen and having proximal and distal ends, said body having a plurality of perforations therein, and
- at least one plunger comprising a scraper, a line, and a handle,
- said scraper originally positioned in the distal end and movable longitudinally from the distal end to the proximal end within said lumen, constructed of a core material with a disk attached thereto, said scraper being sufficiently rigid to withstand the force necessary to loosen any material or debris collected within said lumen, and sized to be just smaller than the diameter of said lumen,
- said line extending through said lumen and having a first end attached to said scraper and a second end attached to said handle, and
- said handle positioned near the proximal end of the body.
A surgical drain for draining wounds comprising:
- an elongated tube-like body forming a lumen and having proximal and distal ends, said body having a plurality of perforations therein, and
- a plunger comprising a solid scraper, a line, and a handle, said solid scraper originally positioned in the distal end and movable longitudinally from the distal end to the proximal end within said lumen, said line extending through said lumen and having a first end attached to said scraper and a second end attached to said handle, and said handle positioned near the proximal end of the body.
A surgical drain for draining wounds comprising:
- an elongated tube-like body forming a lumen and having proximal and distal ends, said body having a plurality of perforations therein, a vacuum port in the proximal end, and a diaphragm attached to the proximal end,
- at least one plunger comprising a scraper, a line, and a handle,
- said scraper originally positioned in the distal end and movable longitudinally from the distal end to the proximal end within said lumen, constructed of a foam material with a plastic disk attached thereto, said scraper being sufficiently rigid to withstand the force necessary to loosen any material or debris collected within said lumen, and sized to be just smaller than the diameter of said lumen,
- said line extending through said lumen and having a first end attached to said scraper and a second end attached to said handle, and
- said handle positioned near the proximal end of the body.
