Abstract

The invention proposes a techniqueto detect a patient probe dislodgement while utilizing a warmer or incubator. The technique includes a capacitive sensing with a single cap sensor. The single cap sensor covers a probe head partially and is either self-capacitance based or mutual capacitance based. The capacitive sensors include a minute printed circuit board (PCB), sensor pad and hatched ground. The capacitive portion is put into the probe head with a dedicated cable running from the probe head to a main board.

PATIENT PROBE DISLOGEMENT ALARM SENSING UTILIZING CAPACITIVE TOUCH SENSE

FIELD OF INVENTION

The invention generally relates to a patient probe and more particularly toa dislodgment alarm for the patient probe.

BACKGROUND OF THE INVENTION

Generally, patient probes are displaced or accidentally removed from an infants’ skin while utilizing in a warmer or incubator. Removal of patient probes results in heater running high or low which results in hyperthermia or hypothermia. Due to hyperthermia or hypothermia overall development of the child is affected in long run.

It would be desirable to have an efficient technique to detect patient probe accidental dislodgement.
