ANTISEPTIC PREOPERATIVE APPLICATOR

摘要

A liquid dispenser applicator for preoperative preparation of a target area of a patient's skin is comprised of two integrated components, a handle portion (12) and a canister vessel (28). The two components are locked by a locking and sealing ring mechanism (34, 36) to prevent accidental rupture of the sterile antiseptic fluid in the canister vessel. When the lock (34) is unlocked, the unit contains a perforator (22) designed to initially slit the membrane followed by pushing it open further and thereafter venting it to provide dual-staged self-venting by the perforator for ease of flow.
