A heat flux sensor is used in conjunction with a patient sensor, such as a patient temperature sensor, and which is secured to the patient in close proximity to the patient sensor. The heat flux sensor monitors the heat flux between the patient and the environment. Upon dislodgement of the patient probe, the heat flux sensor senses a change in heat flux that is of a predetermined amount and provides a signal indicating that the patient probe has become partially or fully dislodged from the patient. In the case of a patient heat sensor, the use of a heat flux sensor provides a quicker and larger signal than would be seen by merely monitoring the change in temperature due to partial or full probe dislodgement.

System for detection of probe dislodgement

An infant care center or infant care warmer having as it source of heat, an infrared emitter that is located above the infant bed and which is relatively small in dimensions so as to not impede the access to the infant by attending personnel at any time, including when X-rays are being taken to the infant. The emitter is contained in a sealed emitter assembly and includes a lens that focuses and directs the infrared radiation to a desired footprint on the infant bed. In a specific embodiment, the infrared emitter is shaped generally in the form of a parabola and a honeycomb material comprising a plurality of hexagonal openings receives the infrared radiation from the parabolic shaped emitter and redirects the radiation into a desired pattern toward the infant bed.
