Abstract

PURPOSE:To auomatize the start of a temperature examination, to simplify the temperature examination and to prevent the variance from being generated in a measured temperature by detecting a motion of lips by a mouth opening/closing detecting means and detecting an opening/closing state of a mouth. CONSTITUTION:First of all, a person to be measured holds a clinical thermometer, carries it to the vicinity of a mouth by observing visually a collimator 7, and thereafter, when a power source switch 1 is turned on, a READY pilot lamp 5 is turned off. Also, a driving signal is sent to a light emitting part 11 through a drive modulating part 32 from a CPU 25 and light is emitted. Subsequently, an analog switch 23 selects a photodetecting part 12 of a mouth opening/closing detecting means 10, a reflected light is photodetected and signal data is read in and stored. Next, after the READY pilot lamp 5 is turned on, the analog switch 23 selects a reference temperature measuring sensor 13, reference temperature data is read in and a reference temperature is stored and processed. Thereafter, the analog switch 23 selects an infrared-ray sensor 9 side, infrared-ray data is read in, and it is subjected to conversion processing to temperature difference data. Subsequently, from this temperature difference data and reference temperature data, a temperature value of the part to be measured is calculated and stored. Next, a peak holding value of a temperature calculated value is displayed by a display part, and after a prescribed time elapses, the temperature examination is finished by sounding a buzzer 33 for informing the end of the temperature examination.

First, the person to be measured holds the thermometer of the present invention in his/her hand and brings it close to the oral cavity while visually positioning the sighting device 7, and then turns on the power switch I to start, and it is initialized in step S1. As a result, the flag on the flowchart is reset to "0", and R
The EADY indicator light 5 goes out and the reference voltage ■. is calibrated. Further, a drive signal is sent from the CPU 25 to the light emitting section 11 of the mouth opening/closing detection means 10 via the drive modulating section 32, and the light emitting section 11 emits light. Then, in step S2, the analog switch 23 activates the light receiving section 1 of the mouth opening/closing detection means 10.
2 is selected, and in step S3 it is determined whether or not it is sampling timing. If it is not sampling timing, wait; if it is sampling timing, step S4
The light receiving section 12 receives the reflected light based on the light emitted from the light emitting section 11, reads the signal data, and stores it. Then, in step S6, it is determined whether the signal level is such that the mouth opening/closing detection is possible, and
Determine whether or not it is in an open state. The determination as to whether the signal level is detectable is made using the reference voltage V shown in FIG. The determination is made based on whether the signal voltage is higher than the reference voltage V I O shown in FIG. It is determined that the open state is present only when the voltage difference is larger than the reference voltage difference, or when both of the above conditions are met.

On the other hand, if it is determined in step S6 that the signal level is not at which the mouth opening/closing detection is possible and the mouth is not open, it is determined in step SIO whether or not the READY indicator light 5 is lit, and if it is lit, the temperature is measured in step Sll. After setting the start flag and making it "B", the READY indicator light 5 is turned off in step S!2, and the process proceeds to step S14.
If it is determined that the READY indicator light 5 is not lit, the temperature measurement start flag is set to "1" in step S13.

. This means that the state of opening and closing the mouth cannot be detected. Therefore, in such a case, it is necessary for the person taking the temperature to bring this thermometer close to the oral cavity until the READY indicator light 5 lights up, and bring it to a position where the open/closed state of the mouth can be detected.
