US 4,066,072 A · Comfort cushion for infants

Abstract

A comfort cushion for infants comprising in combination a fluid filled flexible elastic hermetically sealed infant supporting mattress; a pulsating fluid pump means having mattress inlet and outlet fluid conducting conduits communicating between the pump means and the mattress for circulating a substantially non-compressible fluid through the mattress; and an infant heart beat and breathing alarm means having sensor means embedded in a mattress infant supporting surface for actuating an alarm means external to the mattress if an infant supported on the mattress were to stop breathing or its heart were to stop beating or if either breathing or heart beat were to change such as to indicate peril to the infant. The mattress inlet conduit has a pressure activated valve within the mattress which opens at a pre-selected fluid flow pressure and closes upon the pressure dropping below a lower pre-selected pressure to simulate sounds and fluid movement conditions a pre-born infant experiences.

A comfort cushion for infants comprising in combination:

a fluid filled flexible elastic hermetically sealed infant supporting, elongated mattress filled with a substantially non-compressible fluid, said mattress having a fluid inlet conduit and a fluid outlet conduit sealably attached to and opening into the mattress, said inlet conduit having a pressure actuated valve means within a fluid containing chamber of the mattress for permitting said fluid to flow into the chamber only at a pre-selected fluid pressure, said mattress having a removable fill plug therein for filling and emptying said mattress with said non-compressible fluid;
and
a fluid pulsating pump means having a fluid exhaust conduit sealably connected to the said inlet conduit and a fluid intake conduit sealably connected to said outlet conduit, said pump and valve means for pulsatingly circulating said fluid into and out of said mattress in a manner simulating the sounds and movements a pre-born infant is subjected to.

A comfort cushion for infants comprising in combination:

a fluid filled flexible elastic hermetically sealed infant supporting elongated mattress filled with a substantially non-compressible fluid and having a fluid single conduit means sealably attached to an opening into the mattress at a conduit mattress connecting end, said conduit mattress connecting end opening into the mattress through a pressure actuated bivalve means, said bivalve means having a first valve means for opening an inlet conduit portion of said single conduit and permitting fluid to flow only into the mattress at a first pre-selected pressure and a second valve means for opening an outlet portion of said single conduit and permitting fluid to flow only out of the mattress at a second pre-selected pressure;
and a reciprocating pump means sealably connected to said single conduit at a conduit pump connecting end oppositely disposed from said mattress connecting end, said pump means for reciprocatingly pumping said fluid into and out of said mattress through said single conduit, said mattress further having a removable fill plug means therein for filling and emptying said mattress and having a top surface for supporting an infant thereon, said bivalve means and pump means for providing movement of said supported infant and sounds in a manner for simulating the movement and sounds to which a preborn infant is subjected.
