Abstract: A device and method are provided for positioning an infant's hips, and for maintaining the hip joint in a physiological position, during early months of life. The hip-positioning device includes a flexible base having a pair of opposed, outwardly extending side portions. The side portions are dimensioned for supporting thighs of an infant at an acute angle greater than zero relative to a dorsal plane of the infant, with knees of the infant in a flexed position. The base further has a downwardly extending, generally central portion that is adapted for positioning between the infant thighs and dimensioned for retaining the infant thighs in an abducted position. The device additionally includes an element for retaining the base on the infant.

Abstract: An infant swaddle blanket that includes a torso wrap section with wings and a leg pouch for the infant's legs. The torso wrap section is designed to wrap around the infant's torso for swaddling. The swaddle includes various hook and loop fasteners which facilitates swaddling and makes the swaddle easier to use, as well as making the swaddle safer to use by providing a more secure, adjustable fit. External hold-down straps augment hook and loop closures on the wings. The leg pouch permits the infant's diaper to be changed without unwrapping the torso wrap section, thereby facilitating diaper changes.

Abstract: A swaddling accessory attachable to a wearable blanket for use in swaddling an infant. The wearable blanket can be used with or without the swaddle to give the caregiver the option of using the wearable blanket without the swaddling accessory. The swaddling accessory and wearable blanket are equipped with fasteners that allow the swaddling accessory to be detachably secured to the wearable blanket in different positions relative to the blanket. The fasteners are positioned to prevent the swaddling accessory from being wrapped too high on the infant's body where it could potentially cover a portion of the mouth or nose. The infant's legs are left free to flex within the wearable blanket which helps to prevent hip dysplasia.

Abstract: Safety features for a crib mattress are described. One safety feature is designed to maintain airflow to a fan inlet despite the fan inlet being blocked by a mattress sheet. Another safety feature removes obstructions to airflow within the mattress so that air is dispersed more uniformly across the sleep surface which is formed by a taut sheet of fabric. Yet another safety feature is designed to help retain a fitted sheet on a mattress and make it difficult for the sheet to be inadvertently pulled off the mattress.

Abstract: A system to significantly improve the air quality in a personal breathing environment. The system includes a blower unit that produces a conditioned air flow, a delivery system that delivers air provided by the blower unit to a person's breathing zone, and a conduit that interconnects the blower unit and the delivery system for directing conditioned air from the blower unit to the delivery system. The delivery system is positioned so that it sends conditioned air around an individual's head and into the individual's personal breathing zone, thereby creating a zone of conditioned air around the individual's head.

Abstract: A mattress assembly, comprising: substantially nonporous bottom and side walls forming a mattress foundation; a mattress inner core disposed in the mattress foundation being permeable to air; nonporous top cover covering the mattress inner core, the nonporous top cover having apertures at predetermined locations to allow the flow of air therethrough; and a fan disposed with the mattress assembly for forcing air into the mattress inner core whereby the air is forced out the top cover so as to reduce the accumulation of carbon dioxide in bedding on the top cover of the mattress.

Abstract: A method for quantifying airflow, in the form of a measured airflow rate, through a porous surface. The method is particularly useful for ventilated sleep surfaces used to prevent SIDS. Provided that one knows the correlation between air flow rate and CO2 washout times, the resulting measured airflow rate provides an indication of whether a ventilated sleep surface is providing sufficient airflow to effectively dissipate the CO2. One can determine the minimum measured airflow rate that is effective to provide a minimum adequate level of CO2 dispersal. Thus, a ventilated sleep surface system that produces an air flow sufficient to result in the minimum airflow rate, as measured by a suitable airflow meter, can effectively dissipate CO2 and reduce the risk of SIDS.
