Abstract: An insufflation system for creating a high-flow, constant pressure pneumoperitoneum, the system including: a gas flow distribution device including: a housing defining an insufflation chamber: an inlet port on the housing and configured to be connected to an insufflator to provide insufflation gas from the insufflator to the insufflation chamber; and a plurality of outlet ports on the housing configured to be connected to a plurality of trocars, each outlet port configured to be connected to a dedicated one of the plurality of trocars, to concurrently distribute the insufflation gas from the insufflation chamber to each of the plurality of trocars.

Abstract: A neck warmer has a flat, pliable, substantially rectangular body. The rectangular body has first and second ends and top and bottom edges, and further has first and second opposite exterior surfaces, bounded by the first and second ends and top and bottom edges. First fastening means are attached to the first surface of the rectangular body proximate to the first end, and second fastening means are attached to the second surface of the rectangular body proximate to the second end. The first and second ends of the rectangular body are removably fastenable to each other at the first and second fastening means. The first and second fastening means are positioned such that when the first end is attached to the second end, the rectangular body forms a tube having inner and outer circumferential surfaces provided by the first and second exterior surfaces of the rectangular body. The tube is dimensioned to fit around a wearer's neck.
