Abstract
An apparatus is described for the emergency respiration of a patient which is packed to be very small and which achieves the state of use of the respiratory mask in routine operation through volume growth of a foam body.
Claims6
A packagable respiratory mask system comprising:
- a respiratory mask having a shape-retentive body of a compressible foam material, the body having a first inoperative state in which the body is compressed for transport and a second operative state where the body expands to a predetermined size and shape for use about the mouth and nose of a human;
- a housing which contains the mask foam body in the first state, the housing having predetermined dimensions that restrain the shape-retentive mask foam body from expanding from the first state to the second state at a size slightly smaller than the housing's predetermined dimensions;
- and
- a release mechanism on the housing operable to allow release of the mask foam body from the restraint of the housing so that the shape-retentive body shifts from the first inoperable state to the second operable state.
