First Claim
Patent Images
1. An aspirator system comprising:
- an air channel movable between a collapsed state and an extended state, said air channel comprising;
an aspirator body having a longitudinal axis,an aspirator barrel in translating engagement with said aspirator body, anda nozzle assembly disposed within said aspirator body, and configured to direct gas through said air channel; and
a pressure removable block, configured to seal said air channel in said collapsed state,wherein said aspirator barrel is configured to extend from said aspirator body in response to a first pressure, said first pressure created in response to gas directed through said air channel against said pressure removable block, andwherein said pressure removable block is configured to unseal said air channel in response to a second pressure, said second pressure created as gas is directed through said air channel against said pressure removable block.

Abstract
An aspirator system is disclosed comprising a collapsible/extendable aspirator air channel, wherein a burstable seal for entrapping air across the exit channel is provided, wherein said entrapped air creates a pressure causing the aspirator to extend to its extended state, whereupon the seal bursts and opens the air channel.
