1. A collapsible reservoir system comprising:

  • a manually collapsible reservoir filled with gas;

    a first tube pneumatically connected to the manually collapsible reservoir; and

    a manually collapsible second tube pneumatically connected and continuously open to the manually collapsible reservoir, said second tube configured to generally remain open in the absence of an externally applied compressive force, said second tube being positioned relative to the collapsible reservoir such that a manual compressive force applied to the collapsible reservoir simultaneously compresses and thereby restricts the second tube to increase the back pressure within the manually collapsible reservoir to direct gas from the reservoir through the first tube.
