Gas Seal Pad
A pad is provided having a body for providing a gas seal over a surgical site, a port extending between a first surface of the body and a second surface of the body and sized accept a surgical instrument, and a lumen situated along the body and having a first opening and a second opening, the second opening aligned with the surgical site for communicating a fluid flow to the surgical site.
1 . An apparatus comprising:
a body sufficiently flexible for conforming to a surface about a surgical site to provide a fluid-tight seal thereabout, the body having a bottom surface extending across the body;
a lumen extending from an edge of the body inward and designed to flex along with the body while maintaining a pathway for fluid to flow therethrough; and
a port positioned adjacent a distal end of the lumen and extending between a top surface of the body and the bottom surface of the body, the port sized to provide a fluid-tight seal when a surgical instrument extends thereacross.
2 . The apparatus of claim 1 , further comprising one of a flap, septum, a one-way valve, or combinations thereof for sealing the port.
3 . The apparatus of claim 1 , further comprising a tube extending from the distal end of the lumen toward the surgical site to enhance delivery of the fluid flow to the surgical site.
4 . The apparatus of claim 3 , wherein the tube extends through the lumen.
5 . The apparatus of claim 3 , wherein the tube forms a fluid-tight seal with the lumen.
6 . The apparatus of claim 3 , wherein the tube is coupled to a fitting proximate to the lumen.
7 . The apparatus of claim 1 , further comprising a tab extending from the body to provide a finger grip to facilitate removal of the body.
8 . The apparatus of claim 1 , further comprising an adhesive disposed over at least a portion of the bottom surface of the body to aid in forming the fluid-tight seal over the surgical site.
9 . The apparatus of claim 8 , wherein the body includes an adhesive-free zone surrounding the port to permit local lateral displacement of the body.
10 . The apparatus of claim 1 , wherein the port is sized to form a fluid-tight seal with the surgical instrument.
11 . An apparatus comprising:
a body sufficiently flexible for conforming to a surface about a surgical site to provide a fluid-tight seal thereabout, the body having a bottom surface extending across the body;
a lumen radially extending along the body and designed to flex along with the body while maintaining a pathway for fluid flow therethrough; and
a port extending between a top surface of the body and the bottom surface of the body, the port sized to provide a fluid-tight seal when a surgical instrument extends thereacross.
12 . The apparatus of claim 11 , further comprising one of a flap, septum, a one-way valve, or combinations thereof for sealing the port.
13 . The apparatus of claim 11 , further comprising a tube extending from a distal end of the lumen toward the surgical site to enhance delivery of the fluid flow to the surgical site.
14 . The apparatus of claim 13 , wherein the tube extends through the lumen.
15 . The apparatus of claim 13 , wherein the tube forms a fluid tight seal with the lumen.
16 . The apparatus of claim 13 , wherein the tube is coupled to a fitting proximate to the lumen.
17 . The apparatus of claim 11 , further comprising a tab extending from the body to provide a finger grip to facilitate removal of the body.
18 . The apparatus of claim 11 , further comprising an adhesive disposed over at least a portion of the bottom surface of the body to aid in forming the fluid-tight seal over the surgical site.
19 . The apparatus of claim 18 , wherein the body includes an adhesive-free zone surrounding the port to permit local lateral movement of the body.
20 . The apparatus of claim 11 , wherein the port is sized to form a fluid-tight seal with the surgical instrument.
