1. A surgical access device comprising:
a housing;
a tubular member extending distally from the housing; and
a collar repositionable along the tubular member, the collar having:
a proximal wall,
a distal wall,
first and second sidewalls having a circular configuration, the first and second sidewalls joining the proximal and distal walls thereby defining a circular configuration of the collar,
a cavity defined between the proximal wall, the distal wall, the first sidewall, and the second sidewall, the cavity configured to store a quantity of a fluid therein,
pores extending through the distal wall, each pore configured to allow a predetermined quantity of the fluid to flow therethrough, and
a port disposed through the proximal wall and in fluid communication with the cavity, the port configured to allow the fluid to be introduced into the cavity.
