Abstract
A controller for self-refilling resuscitation enclosures has a pair of arms pivotable between open and closed positions, an inside strap fixed to both arms, and an outside strap fixed to one arm. The outer strap can be releasably coupled at any one of a series of locations along the other arm, to selectively limit the amount of resuscitation bag recovery and thereby adjustably control the expansion or recovery volume of the enclosure. The straps, along with portions of the arm inside surfaces, maintain a contiguous wrapping engagement about the resuscitation enclosure throughout its compression and expansion, to positively secure the enclosure. The arms afford a mechanical advantage to reduce user fatigue, and provide for the tactile sensing of lung compliance during resuscitation.
