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.

First claim

The invention claimed is:

1. An aspirator method comprising:
pressurizing an air channel, said air channel being at least partially defined by an aspirator barrel in translating engagement with an aspirator body, wherein the air channel is sealed with a seal coupled to an opening of the aspirator barrel, wherein in response to pressurizing the air channel, the aspirator barrel translates along the aspirator body to transition from a collapsed state to an extended state; and
in response to the aspirator barrel being in the extended state, further pressurizing the air channel to burst the seal.

2. The aspirator method of claim 1 , wherein the aspirator barrel comprises an extendable channel wall comprising telescoping segments, wherein the telescoping segments friction lock together in response to the aspirator barrel transitioning to the extended state.

3. The aspirator method of claim 1 , further comprising inflating an inflatable device via the air channel.
