摘要：
A fluid medical waste canister has interior surfaces that are exposed only to compressive stresses when a vacuum is applied, thereby eliminating the potential for environmental stress cracking. The canister is compatible with medical procedures that generate fluids having high fat/lipid content, such as liposuction procedures. The canister avoids certain stress concentration distributions that cause cracks to close onto themselves, which can cause one or more pieces of the canister wall to rupture into its interior volume. Because the canister is designed to avoid conditions that initiate canister implosion during liposuction procedures, low-cost polystyrene may be used as a waste canister material for such procedures.
