Portable resuscitation apparatus
First Claim
1. A portable resuscitation apparatus, comprising,a portable support means having top and bottom portions,a support member extending upwardly from said support means adapted to support the patient'"'"'s neck to position the patient'"'"'s head for resuscitation,a manually operated air supply means mounted on said support means,a flexible mask means having an air inlet supply base extending therefrom which is in operative communication with said air supply means,and connector means for detachably connecting said mask means to the patient'"'"'s face and to maintain the patient on said support member,said air supply means comprising a flexible bellows pump mounted on said support means,said support means having a first air passageway formed therein which is in communication with said pump, said base being in communication with said air passageway whereby compression of said flexible bellows pump will supply air to said mask means,said bellows pump being movable between compressed and extended positions, a spring means in said bellows pump for yieldably resisting the compression of said bellows pump and for moving said bellows pump from its compressed position to its extended position,said spring means being of the two-stage type so that said spring means will yieldably resist, at a first predetermined rate, the compression of said bellows pump during a predetermined initial portion of its compression stroke and will yieldably resist, at a rate greater than said first predetermined rate, during a predetermined portion of its compression stroke after said initial portion.

Abstract
A portable resuscitation apparatus is described including a flat support having a neck cushion at one end thereof to properly position the patient'"'"'s head and to also provide a secure means for attaching a mask to the patient'"'"'s face and head. The mask includes a pair of cheek straps extending therefrom which are secured to opposite sides of the neck cushion. A flexible strap is secured to the upper central portion of the mask and to the neck cushion. A flexible hose extends from the mask to a ventilation pump mounted on the support whereby compression of the pump will cause air to be forced through the flexible hose to the mask. The mask includes a first valve provided therein which permits communication from the atmosphere of the interior of the mask during the times that the pump is not being operated. The mask also includes a second valve which is vented to the atmosphere upon a predetermined pressure being reached within the mask. A source of oxygen is in communication with the flexible hose so that the ventilation pump will supply pure oxygen to the patient during the initial portion of the ventilating action. An electronic rhythm unit is mounted on the support for indicating the prescribed beat for proper closed chest massage and ventilation.
