Three-in-one thermometer

Abstract

A three-in-one thermometer includes a housing, a control board disposed within the housing, and a sensor assembly electrically connected to the control board. The sensor assembly is integrated at an insertion portion at one end of the housing, enabling synchronous measurement of body temperature, blood oxygen saturation, and heart rate during a single insertion. By integrating multiple sensors at a front end of the insertion portion and processing signals through a single control board, the thermometer achieves physical and functional integration of multiple physiological measurements. A detachable housing facilitates cleaning, while a sensor fixing bracket, a metal cap window, sealing rings, and waterproof plugs ensure accurate positioning, reliable measurement, and safe operation.
