P-vac is a sterile, disposable and portable system used for closed wound drainage which offers a more constant suction profile than 3-spring evacuators, resulting in the potential for improved tissue approximation and reduced risk of hematoma. It is sterile, disposable and portable system used for closed wound drainage. It generates approximately -60c mH?O to -90 cmH?O stronger than other systems to maximize collapse-resistance. The systme features in a precompressed state with a standard Y-connector for dual drainage. Features/Benefits Closed System Design reduces the chance of cross contamination. Compact and Self Contained System allows complete patient ambulation. Pre-compressed State of Package saves the shipping cost and storage space. Y-connector for Bilateral Drainage. Attached Stepped Adapters allows connecting to other sizes on demand which facilitates easy connection to drainage system. Internal Anti-reflux Valve is incorporated to prevent reverse flow during emptying and reactivation. Reclosable Pouring Spout permits convenient emptying of the reservoir unit and system reactivated when required. Transparent Sidewall with Clearly Marked Graduations at 25 cc Increments facilitates quick and easy identification and measurement of exudate.
