Remote sensing infant warmer
First Claim
Patent Images
1. An infant warmer comprising:
- a base;
a tray mounted above the base;
a support extending from the base;
a fixture mounted to the support and extending over the tray;
a radiant heater disposed within the fixture configured to emit radiant energy so as to warm an infant placed in the tray;
a detector disposed proximate the fixture and configured to receive infant radiated energy;
an interruptor configured to at least intermittently at least partially block the heater radiant energy thereby reducing radiant energy reflected from infant skin at the detector during measurements of the infant radiated energy; and
a controller in communications with the detector and the radiant heater, the controller configured to vary the radiant energy from the radiant heater responsive to measurements of the infant radiated energy so as to provide closed-loop regulation of infant warmth.

Abstract
An infant is illuminated with heater radiant energy so as to warm the infant. A detector remotely senses infant radiated energy so as to determine the extent of infant warmth, and a controller responsive to the detector regulates the heater radiant energy accordingly. Skin-reflected heater radiant energy is limited at least during measurements of infant radiated energy.

8. An infant warmer method comprising the steps of:
-
providing a heater to generate radiant energy to be absorbed by at least a portion of an infant; at least partially interrupting skin-reflected heater radiant energy from being detected by a detector; remotely sensing during the at least partial interrupting, infant radiated energy responsive to the heater radiant energy; and adjusting, responsive to the sensed infant radiated energy, the heater radiant energy that reaches the infant so as to control infant warmth. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An infant warmer comprising:
-
means for holding an infant; means for warming an infant; means for positioning the means for warming so as to warm an infant; means for remotely sensing infant radiated energy; means for at least reducing skin-reflected radiant heater energy from affecting an accuracy of sensing infant radiated energy; and means for close-loop regulation of infant warmth in response to an output from the means for remotely sensing. - View Dependent Claims (16)
