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.
Claims20
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, and
- a 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, and
- wherein 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.
5 more elements
An aspirator method comprising:
- pressuring an air channel, said air channel being sealed with a seal, said air channel having extendable channel walls, and being in a collapsed state;
- extending an aspirator barrel in response to an extending pressure;
- and
- bursting said seal in response to a burst pressure.
1 more element
An aspirator method comprising:
- sealing an air channel with a seal to create a pressurizable enclosure, said air channel forming an aspirator system,
- pressurizing the air channel to form an extending pressure against the seal.
