Abstract

A device for use with very small newly born or premature infants to monitor and prevent the onset of a Sudden Infant Death Syndrome event. A pulse oximeter is mounted in an opaque foot wrap, which is wrapped around the infant'"'"'s foot in the area of the arch and ball of the foot The foot wrap is connected to a second wrap, which is wrapped around the ankle. The ankle wrap secures the foot wrap portion from rotational motion or from sliding forward toward the toes on an infant'"'"'s foot. Blood oxygen and pulse read-outs on the pulse oximeter are transmitted to a monitor kept by the caregiver. Visible read-outs for the blood oxygen or pulse are shown on the monitor. The monitor sounds an alarm if the infant'"'"'s blood oxygen drops to a predetermined level for a predetermined time. When not in use, the device is recharged on a stand.

Claims

1. A portable adjustable cordless device to alert caregivers to the onset of a Sudden Infant Death Syndrome occurring in a premature, newly born, or very small infant comprising:

(a) a foot mounted apparatus wherein;

said apparatus has self-contained means for determining blood oxygen levels;

said apparatus has means for securing said means for determining in the plantar/arch area of an infant'"'"'s foot so that said means for determining does not move forward and backward on an infant'"'"'s foot or rotationally around an infant'"'"'s foot;

said apparatus has self-contained cordless means for transmitting said blood oxygen levels determined by self-contained means for determining blood oxygen;

said apparatus has first means for powering said self-contained blood oxygen determining means and said self-contained transmitting means;

(b) a monitor to be kept with a caregiver wherein;

said monitor has means for receiving transmissions of blood oxygen determination from said cordless transmission means in said apparatus, said blood oxygen determination being made by said self-contained determining means in said apparatus;

said monitor has means for processing blood oxygen determinations;

said monitor has means for sounding an audible alarm at blood oxygen determinations fall below a predetermined level and;

said monitor has a second means for powering said receiving means, processing means, and said sounding means;

whereby a caregiver may secure the foot mounted apparatus around a foot of an infant and placing an infant so fitted with the foot mounted apparatus into a bed or other resting position and leaving an infant unattended but keeping said monitor with a caregiver so that a caregiver may listen for said audible alarm and so be alerted to an onset of Sudden Infant Death Syndrome.

2. A portable adjustable cordless device of claim 1 wherein said means for securing comprises an adjustable plantar/arch portion of the apparatus to wrap around a plantar/arch area of an infant'"'"'s foot in a snug fashion and be secured against movement from a toe area of an infant'"'"'s foot toward an ankle area of an infant'"'"'s foot;

an ankle wrap portion of the apparatus to wrap around an ankle of an infant'"'"'s foot and connected to the plantar/arch wrap portion of the apparatus by a connecting portion so that the plantar/arch wrap portion of the apparatus is secured against motion from an ankle area of an infant'"'"'s foot toward a toe area of an infant'"'"'s foot and also is secured against a rotating motion around an infant'"'"'s foot by the connecting portion secured to an ankle wrap portion of the apparatus, whereby said means for determining is fixedly mounted on an infant'"'"'s foot in the plantar/arch area of an infant'"'"'s foot and secured from forward or backward motion or rotational motion around an infant'"'"'s foot.

3. A portable adjustable cordless device of claim 2 wherein said self-contained means for determining blood oxygen levels is a pulse oximeter mounted in the plantar/arch area of an infant'"'"'s foot and secured within the adjustable portion of the apparatus that wraps around a plantar/arch area of an infant'"'"'s foot.

4. A portable adjustable cordless device of claim 3 wherein said adjustable portion of the apparatus to wrap around the plantar/arch area of an infant'"'"'s foot is constructed of opaque material, whereby ambient light does not result in artifactual readings of blood oxygen levels taken by said pulse oximeter.

5. A portable adjustable cordless device of claim 4 wherein said foot mounted apparatus is constructed, at least in part, of stretchy elasticized material.

6. A portable adjustable cordless device of claim 5 wherein for said pulse oximeter a light emitter is mounted on the top of an infant'"'"'s foot and a light sensor is mounted on the bottom of the infant'"'"'s foot in the plantar/arch area of an infant'"'"'s foot.

7. A portable adjustable cordless device of claim 6 wherein said first means for powering and said second means for powering are batteries.

8. A portable adjustable cordless device of claim 7 wherein said monitor has means for displaying pulse readings generated by said pulse oximeter.

9. A portable adjustable cordless device of claim 8 wherein there is a first means for warning a caregiver wherein said first set of batteries is becoming depleted and a second means for warning a caregiver when said second set of batteries is becoming depleted.
