Abstract

(57) [Summary] [Problem] With an existing electronic thermometer, since the lead wire connected to the thermistor does not contact the metal cover of the temperature sensor, the space inside the metal cover is large, and most of the heat is consumed. And the measurement time becomes longer. The measured body temperature is transmitted only to the thermistor, not to the lead wire. Therefore, the temperature difference between the lead wire and the thermistor increases, and when the lead wire conducts heat, the amount of heat of the thermistor is lost, and the measurement time becomes longer. SOLUTION: The present invention adopts a method in which a heat insulator that is difficult to conduct heat presses the thermistor and the lead wire, so that the heat insulator is firmly attached to the inner wall of the metal cover, and when measuring body temperature, the thermistor and the lead are used. The wires are heated simultaneously, the temperature difference between the thermistor and the lead wire is reduced, unnecessary heat loss is avoided, and body temperature measurements are made faster.

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a temperature sensor for a thermometer that measures body temperature speedily. Book The thermometer temperature sensor invented is that the thermistor and the lead wire feel heat at the same time. The body temperature can be measured quickly.

[0002]

[Prior art]

  Thermometers are widely used as a tool for measuring body temperature in daily life. . There are two types of thermometers currently on the market. One is a liquid thermometer, Liquid (mercury) receives heat to change its volume, which measures body temperature. It This type of thermometer does not return to its original state immediately after use, so it is inconvenient to use. is there. In addition, since a large amount of mercury is used as a medium for transmitting body temperature, heat transfer The speed is slow. In addition, when it is no longer in use, it is difficult to collect it, and it may There is also a problem. The other is an electronic thermometer. See Figure 1. This type is an American patent number US6,419,388B2 MEDICAL THERMOMETER thermometer Then, the body temperature is sensed with a thermistor, and the body temperature after measurement is measured with a lead wire. It is designed to be displayed to Rement.

[Problems to be solved by the device]

  However, in the existing electronic thermometer, the lead wire connecting to the thermistor is a temperature sensor. Since it does not contact the metal cover of the sir, the space inside the metal cover is large Heat is consumed and the measurement time becomes longer. The measured body temperature is It does not reach the lead wire. Therefore, between the lead wire and the thermistor When the temperature difference becomes large and the lead wire conducts heat, the heat of the thermistor is taken away. No, the measurement time becomes long.

[0004]

[Means for Solving the Problems]

  The present invention is to fill the inside of the metal cover of the temperature sensor with a heat insulator that is difficult to transfer heat, The heat insulator presses the thermistor and two lead wires against the inner wall of the metal cover. It is fixed. Two thermistors are pressed against the leading edge of the inner wall of the metal cover. The lead wires of each of them, or together, are attached to the inner wall of the metal cover. With, it is firmly fixed.   The present invention says that the heat insulator, which is difficult to transfer heat, holds down the thermistor and the lead wire. By adopting the method, it is firmly attached to the inner wall of the metal cover, When measuring body temperature, the thermistor and lead wires are heated at the same time, The temperature difference between the leads is reduced, unnecessary heat loss is avoided, and the temperature measurement is speedy. It is done to Dee.

[Embodiment of device]

  Please refer to FIG. 2 and FIG. The rapid temperature measurement sensor of the electronic thermometer of the present invention Sir is the metal cover 51 and the IC 52 installed inside the thermometer outer case 5. The thermistor 1 and the lead wire 2 are provided inside the metal cover 51. That The outside of the thermistor 1 is fixed to the inner wall of the tip of the metal cover 51 with an adhesive 3. It One end of the lead wire 2 is connected to the thermistor 1, and the other end is outside the thermometer. It is connected to the IC 52 in the case 5. The thermistor 1 is inside the metal cover 51. It is installed and connected to one end of the outer case 5 by a metal cover 51.   The metal cover 51 is filled with a heat insulating body 4 that hardly transfers heat, The body 4 is a material suitable for filling the inside of the metal cover 51. And the thermistor 1 and the lead wire 2 are firmly fixed in the metal cover 51. The heat insulator 4 is gold By filling the inside of the metal cover 51, the thermistor 1 and the lead wire 2 are The heat insulator 4 is fixed at the time of assembly by being fixed to the scale and the inner wall of the metal cover 51. Is also convenient, and it is not necessary to make a hole for the lead wire 2 to penetrate the heat insulating body 4. did Therefore, it is easy to assemble and manufacture.   Please refer to FIG. 3 and FIG. When assembling, the inner wall of the metal cover 51 The thermistor 1 attached to the tip has two lead wires 2 arranged side by side and a metal cover 5 It is attached to the inner wall of 1. Please refer to FIG. 5 and FIG. Metal cover The thermistor 1 attached to the tip of the inner wall of 51 and the two lead wires 2 are made of gold. By being attached to the inner wall of the metal cover 51, inside the metal cover 51 of the sensor By adopting the heat-insulating body 4 filled with heat, which does not conduct heat easily, By pressing the mister 1 and the two conductive wires 2 against the inner wall of the metal cover 51 When measuring the body temperature, the thermistor 1 and the lead wire 2 are heated at the same time, The temperature difference between 1 and lead wire 2 is reduced, unnecessary heat loss is avoided and speed Dee can measure body temperature.   When carrying out the present invention, the thermistor 1 and the lead wire 2 are simultaneously placed in the oral cavity or the armpit. The metal cover 51, the thermistor 1 and the lead wire 2 are inserted into a measurement site such as the bottom of the At the same time, he feels the heat of the human body. Temperature difference of the surrounding environment of thermistor 1 Is small, the temperature of the thermistor 1 rises quickly, the time for measuring body temperature is shortened, and The accuracy is also high. Furthermore, by attaching the lead wire 2 to the inner wall of the metal cover 51, , To feel and heat the body temperature when measuring it, and take away the amount of heat absorbed by the thermistor 1. Less is.
