Surgical underlay pad for securing a patient to an operating table in a Trendelenburg position

A gel pad (100) for use with a surgical underlay pad supporting a torso (40) of a patient lying on a top surface (30a) of an operating table (30) tilted beyond a horizontal plane, the gel pad comprising:

• a flexible substrate (10) having an upper side (10a) and a lower side (10b);
• and
• a gel coat (20) comprising a polyurethane gel material on at least a portion of each of the lower side (10b) and the upper side (10a) of the substrate (10);
• wherein the gel coat on the upper side of the substrate is applied in a first predetermined pattern;
• wherein the gel coat on the lower side of the substrate is applied in a second predetermined pattern different from the pattern on the upper side;
• wherein the gel coat of the gel pad positioned between the top surface of the operating table and the surgical underlay pad, adheres to both the top surface (30a) of the operating table (30) and to the underside of the surgical underlay pad so as to be sandwiched between the top surface (30a) and the underside and adhered thereto;
• wherein the shear strength of the gel coat is of a sufficient strength to prevent the gel pad from sliding across the top surface of the operating table and to prevent the surgical underlay pad from sliding across the surface of the gel pad.

A gel pad (100) for use with a surgical underlay pad configured to support a torso (40) of a patient lying on a top surface (30a) of an operating table (30) tilted beyond a horizontal plane, the gel pad comprising:

• a flexible substrate (10) having an upper side (10a) and a lower side (10b);
• a gel coat (20) comprising a polyurethane gel material on at least a portion of each of the lower side (10b) and the upper side (10a) of the substrate (10);
• and
• a sheet configured to support the torso;
• wherein at least one gel pad is configured to be positioned between the sheet and the torso;
• wherein the gel coat of the gel pad positioned between the top surface of the operating table and the surgical underlay pad, adheres to both the top surface (30a) of the operating table (30) and to the underside of the surgical underlay pad so as to be sandwiched between the top surface (30a) and the underside and adhered thereto;
• and
• wherein the shear strength of the gel coat is of a sufficient strength to prevent the gel pad from sliding across the top surface of the operating table and to prevent the surgical underlay pad from sliding across the surface of the gel pad.
