ABSTRACT:
A bead thermistor air flow sensor assembly comprising bead thermistor and circuit conductor completely encapsulated between upper and lower layers of thin plastic film. The thermistors are mounted adjacent the outer ends of arms adapted to be aligned with the nostrils and mouth of the patient when the sensor assembly is positioned on the face of the patient by double faced mounting tape. The electrical circuit and bead thermistors being fully encapsulated and sealed, the assembly can be immersed in fluid for sterilization between uses. The assembly is thin and very flexible, permitting either face thereof to be applied to the patient to facilitate connection to monitoring equipment which may include an alarm to signal when normal breathing is interrupted.
