A multi-lumen aspirator device having an elongated body with a plurality of lumens disposed therein for reducing the sound level generated during the operation of the device is disclosed. The elongated body defines a proximal opening that communicates with a distal opening through an inner conduit. The plurality of lumens is disposed within the inner conduit such that a central lumen of the plurality of lumens is surrounded by the remaining plurality of lumens such that laminar flow is established through the multi-lumen aspirator that promotes the reduction in sound generated by the multi-lumen aspirator device during operation. |
