【Example】

An embodiment of the present invention will be described below based on the drawings. First, the overall configuration will be explained with reference to FIGS. 2 and 3. Thermometer body 1 is synthetic It is formed into a flat shape from a material such as resin, and a switch 3 is provided on its head. It is. In addition, a sensing part 5 for sensing body temperature is integrated at the lower tip of the thermometer body 1. It is formed. When this sensing part 5 senses body temperature, it outputs an electrical signal according to the body temperature. Strengthen. Inside the thermometer body 1, there is a device that measures body temperature based on electrical signals from the sensing section 5. a sounding circuit consisting of an arithmetic processing unit that performs the measurement, a buzzer that emits a warning sound, etc., which will be explained later; A battery or the like is incorporated to supply power to these circuit sections. In addition, the thermometer body A display section 7 using a liquid crystal or the like is provided in the center of the front of the device 1, and a calculation processing section calculates the The measured value of body temperature is displayed. The front side of the thermometer body 1 is displayed on the lower side of the display section 7. A pair of contacts 9a and 9b are provided on the side and back sides. These contacts 9a and 9b are The pair of contacts 9a and 9b are made of a conductive member and are in contact with a conductor such as the skin. Conducts when touched.

[0008] Next, the configuration of the circuit section incorporated inside the thermometer body 1 will be explained with reference to FIG. do. The sensing section 5 is connected to an A/D conversion circuit 11. The A/D conversion circuit 11 senses The analog signal input from section 5 is converted into a digital signal such as a BCD signal. this The A/D conversion circuit 11 is connected to the arithmetic processing section 13, and receives the converted digital signal. is given to the arithmetic processing section 13. The arithmetic processing unit 13 is based on the information from the sensing unit 5. A temperature measurement circuit that measures body temperature, and a temperature measurement circuit that measures the temperature measured by this temperature measurement circuit. A judgment system that monitors the temperature rise rate and predicts the final temperature when the temperature rise rate decreases. a pulse generating circuit that generates pulses of a predetermined period, and a pair of contacts 9a and 9b. and a conduction state determination circuit that determines the conduction state of the conduction state. The latch circuit 15 calculates Connected to the processing unit 13 and inputs the measured temperature information measured by the temperature measurement circuit unit. At the same time, input the pulse from the above pulse generation circuit, and synchronize with the period of this pulse. The measured temperature information is latched at the corresponding time interval. Display section 7 is connected to latch circuit 15 The measured temperature information from the latch circuit 15 is sequentially displayed. Therefore, the display The measured temperature information displayed in 7 is updated at time intervals corresponding to the period of the above pulse. Ru. Further, the switch 3 is connected to the arithmetic processing section 13 and is also connected via the switch 17. and is connected to the sound generation circuit 19. When switch 3 is turned on, a power supply (not shown) is activated. Power from the pond is supplied to each circuit section. Also, the sound generation circuit 19 is for issuing a warning. Consists of a buzzer, a termination sound generation circuit, etc. to emit a termination sound at the end of the temperature measurement operation. has been done. Further, the arithmetic processing section 13 is connected to a pair of contacts 9a and 9b. If there is continuity between the pair of contacts 9a and 9b, that is, the temperature measurement operation is not performed properly. If it is determined that the switch 17 is on, the switch 17 is turned off. On the contrary, a pair of contacts 9a , 9b is in a non-conductive state, that is, it is determined that the temperature measurement operation is not appropriate. If so, turn on the switch 17. This switch 17 is connected to the above buzzer. ing. Further, the arithmetic processing section 13 is connected to the sound generation circuit 19 via the switch 18. ing. The switch 18 is normally turned off and the rate of increase in the measured temperature is monitored. When the department determines that the rate of temperature rise has decreased, that is, when it determines that the temperature measurement operation has ended. It is turned on by a control signal from the judgment section. This switch 18 emits the above end sound. Connected to live circuit. The speaker 21 is connected to the sound generation circuit 19, and the sound generation circuit 1 The sound signal input from 9 is amplified. This sound generation circuit 19 and speaker 21 give a warning. constitute means.

[0009] Next, the effect will be explained. When measuring the temperature of an infant or child, switch 3 and bring the sensing part 5 into close contact with the armpit or the like. The information from this sensing section 5 is converted to A/D. The signal is supplied to the arithmetic processing section 13 via the conversion circuit 11. Is the arithmetic processing unit 13 the sensing unit 5? Body temperature is measured based on information from At this time, the pair of contacts 9a and 9b comes into contact with a conductor such as the child's skin, and the pair of contacts 9a and 9b becomes electrically conductive. child The switch 17 is turned off by the conduction between the pair of contacts 9a and 9b, and the sound generation circuit 19 is turned off. This prevents the generation of warning sounds. This prevention of generation of the warning sound from the sound generation circuit 19 is as follows. While the pair of contacts 9a and 9b are conducting, that is, the temperature measurement operation is performed properly. continues as long as the

0010 Next, if the infant or child moves around during the measurement, it may be difficult to identify areas such as the armpits. If the electronic thermometer moves out of position, the pair of contacts 9a, 9b and the skin may Bad contact. As a result, if a disconnection occurs between contacts 9a and 9b, the The calculation processing section 13 turns on the switch 17. This causes the sound generation circuit 19 to generate a warning sound. A signal is output, and a warning sound such as "boo" is emitted from the speaker 21. This way In such a state, the temperature measurement operation by the arithmetic processing unit 13 is also interrupted. For this reason, infants or children should correct the digital thermometer so that the warning sound stops. I will do it. Therefore, make sure to measure the body temperature while alerting the infant or child. can be measured. In this way, during temperature measurement, there is a loss of conductivity between contacts 9a and 9b. If a leak occurs, a warning sound will be emitted and the temperature measurement operation will be interrupted, but after that, the contact When 9a and 9b become conductive, the warning sound is prevented and temperature measurement continues. perform an action.

[0011] As mentioned above, if the sensing part 5 is kept in close contact with the armpit etc., the body temperature will be accurately measured. be measured. That is, the measured temperature information measured by the arithmetic processing unit 13 is output to the circuit 15. The measured temperature information from this latch circuit 15 is sequentially displayed on the display section. 7 will be displayed. At this time, the judgment unit monitors the rate of increase in the measured temperature and determines whether the rate of temperature increase is low. If it is determined that the temperature measuring operation has ended, the switch 18 is turned on. child As a result, the end sound signal is output from the sound generation circuit 19, and the predicted reaching temperature is is output to the latch circuit 15 as measured temperature information. Therefore, the final measured temperature information The information is displayed on the display section 7. The mounting position of the pair of contacts is not limited to the above, and may be installed at an appropriate position. You can leave it. For example, connect one of the pair of contacts above to the surface of the thermometer body. At the same time, the other contact point may be provided to the sensing section. Also, the sensor A pair of contacts may be provided integrally. In this case, the close contact between the pair of contacts and the skin However, it is necessary to insulate the contact and sensing part using an insulating material. There is. In addition, in the above example, the reached temperature is predicted when the temperature increase rate decreases, and this The configuration was configured to output the predicted reached temperature as the final measured temperature information, but this The idea is not limited to this, but the final measured temperature information can be output using an appropriate method. can do. For example, you can set a certain measurement time and check the continuity between a pair of contacts. Configure it to output the final measured temperature information when the time reaches the measurement time. By doing so, the circuit configuration of the arithmetic processing section can be simplified and costs can be reduced. I can do it. Also, if a break in contact occurs between contacts 9a and 9b during temperature measurement, The configuration is configured to reset the previously measured temperature information and restart the temperature measurement operation from the beginning. Then, the accuracy of the measured temperature can be improved.
