Abstract

Systems and methods for providing phototherapy to an infant use the determined position and/or posture of an infant to provide effective phototherapy through a set of light sources, to avoid electromagnetic radiation from the light sources directly impinging on the eyes of the infant, and to reduce or limit the level of electromagnetic radiation leaked into the environment.

First claim

The invention claimed is:

1. A phototherapy system for an infant having a face and eyes, the system comprising:
an infant-supporting body configured to support an infant on a top-surface thereof;
one or more sensors that generate one or more output signals conveying information related to a position of the infant on the top-surface of the infant-supporting body;
a set of light sources carried by the infant-supporting body, wherein the set of light sources are configured and arranged such that, responsive to activation of a subset of the set of light sources, electromagnetic radiation emitted by the subset of the set of light sources is guided through the top-surface of the infant-supporting body; and
one or more processors configured to execute computer program modules, the computer program modules comprising:
a position module configured to determine the position of an infant on the top-surface of the infant-supporting body, wherein the determination is based on information from the one or more sensors, and wherein the position includes a direction in which the eyes of the infant are facing; and
a light module configured to control one or more subsets of light sources of the set of light sources based on the determined position of the infant and the direction in which the eyes of the infant are facing such that the emitted electromagnetic radiation provides phototherapy for the infant and such that the emitted electromagnetic radiation does not directly impinge on the eyes of the infant;
wherein the light module is further configured to:
turn down and/or turn off the one or more subsets of light sources proximate to the infant's eyes, in response to a determination that the eyes of the infant are facing the top surface of the infant supporting body; and
cause the one or more subsets of light sources to emit electromagnetic radiation, in response to a determination that the eyes of the infant are facing away from the top surface of the infant supporting body.

2. The phototherapy system of claim 1 , wherein the one or more sensors generate one or more output signals conveying information related to a size of the infant on the top-surface of the infant-supporting body, the system further comprising:
a therapy module configured to determine a recommended phototherapy regimen for the infant based on information related to the size of the infant;
wherein the light module is configured to control one or more subsets of light sources of the set of light sources by adjusting the level of electromagnetic radiation emitted by the one or more subsets of light sources of the set of light sources, wherein the adjustment by the light module is based on the recommended phototherapy regimen.

3. The phototherapy system of claim 1 , wherein the one or more sensors include one or more imaging sensors configured to capture position information of the infant on the top-surface of the infant-supporting body, wherein the position module is furthermore configured to determine a three-dimensional position of the infant based on the captured position information from the one or more imaging sensors, and wherein the light module is further configured to control one or more light sources from the set of light sources based on the determined three-dimensional position.

4. The phototherapy system of claim 1 , wherein the one or more sensors generate one or more output signals conveying information related to a level of leaked electromagnetic radiation emitted by the set of light sources such that the leaked electromagnetic radiation does not substantially contribute to the phototherapy for the infant;
wherein the set of light sources are further configured to emit electromagnetic radiation in a range of directions, and wherein the light module is further configured to control directions of emissions of the set of light sources such that the level of leaked electromagnetic radiation is affected.

5. A method for controlling light sources of a phototherapy system configured to provide phototherapy to an infant having a face and eyes, wherein the phototherapy system includes an infant-supporting body having a top-surface, the method comprising:
generating one or more output signals conveying information related to a position of the infant on the top-surface of the infant-supporting body;
emitting electromagnetic radiation through the top-surface of the infant-supporting body from a set of light sources;
determining the position of the infant on the top-surface of the infant-supporting body based on information from one or more sensors, wherein the position includes a direction in which the eyes of the infant are facing; and
controlling one or more subsets of light sources from the set of light sources based on the determined position of the infant and the direction in which the eyes of the infant are facing such that the emitted electromagnetic radiation does not directly impinge on the eyes of the infant;
wherein controlling the one or more subsets of light sources comprises:
turning down and/or turning off the one or more subsets of light sources proximate to the infant's eyes, in response to a determination that the eyes of the infant are facing the top surface of the infant supporting body; and
causing the one or more subsets of light sources to emit electromagnetic radiation, in response to a determination that the eyes of the infant are facing away from the top surface of the infant supporting body.

6. The method of claim 5 , further comprising:
generating one or more output signals conveying information related to a size of the infant on the top-surface of the infant-supporting body; and
determining a recommended phototherapy regimen for the infant based on information related to the size of the infant,
wherein controlling the one or more subsets of light sources from the set of light sources is accomplished by adjusting the level of electromagnetic radiation emitted by the one or more subsets of light sources of the set of light sources based on the recommended phototherapy regimen.

7. The method of claim 5 , wherein the one or more sensors include one or more imaging sensors configured to capture position information of the infant on the top-surface of the infant-supporting body, the method further comprising:
determining a three-dimensional position of the infant based on the captured position information from the one or more imaging sensors;
wherein controlling the one or more subsets of light sources from the set of light sources is further based on the determined three-dimensional position.

8. The method of claim 5 , further comprising:
generating one or more output signals conveying information related to a level of leaked electromagnetic radiation emitted by the set of light sources such that the leaked electromagnetic radiation does not substantially contribute to the phototherapy for the infant;
wherein the set of light sources are further configured to emit electromagnetic radiation in a range of directions, and wherein controlling the one or more subsets of light sources from the set of light sources includes controlling directions of emissions of the set of light sources such that the level of leaked electromagnetic radiation is affected.

9. A system configured to providing phototherapy to an infant having a face and eyes, the system comprising:
means for supporting an infant, the means for supporting having a top surface;
means for generating one or more output signals conveying information related to a position of the infant on the top-surface of the means for supporting the infant;
means for emitting electromagnetic radiation through the top-surface of the means for supporting the infant;
means for determining the
