Description

The present invention is a thermometer, which is a kind of thermometer that can measure temperature quickly and accurately without waiting for preheating time, especially when a family member is ill in clinics, hospitals or homes and needs frequent use of the thermometer. This is related to a preheating high-speed thermometer.

Regarding the preheating structure of a thermometer, a known technique is disclosed in U.S. Pat. S. Patent No: 6, 109, 784 FAST RESPONSE DIGITAL THERMOMETER (fast response digital thermometer) and U.S. Pat. S. Patent No: 6,250,802 ELECTRONIC
There is THERMOMETER WITH PRE-HEA HEATING (an electronic thermometer with a preheating function). In the thermometer structures disclosed in these, the sensor head is heated in advance mainly by a built-in battery of the thermometer, and the measurement time is shortened.
U. S. Patent No: 6, 109, 784 FAST RESPONSE DIGITAL THERMOMETER (high-speed response digital thermometer) U. S. Patent No: 6,250,802 ELECTRONIC THERMOMETER WITH PRE-HEA HEATING (electronic thermometer with preheating function)

However, the heating by the built-in battery of this type of thermometer has the following drawbacks.
1. Since the capacity of the thermometer internal battery is limited, it consumes electricity for preheating and takes a long time.
2. Since the preheating function needs to be activated before use, a waiting period from the activation to the completion of preheating is necessary.
3. In this type of preheating, the general human body temperature is 35 to 37 degrees Celsius, and when the temperature is measured by moving the thermometer to the human body, the preheating temperature decreases due to the heat dissipation effect. The measurement speed cannot be improved reliably.
4). Since the preheating heater enters the inside of the sensor head, the entire heating volume becomes large and the measurement time becomes long.

Another known preheating type thermometer is provided with a heating case and directly heats the sensor head. Although this type of design has the effect of high-speed heating, the outside of the thermometer's sensor head is heated to raise the temperature, but if the thermometer is taken out of the heating case, the temperature will drop quickly when it comes into contact with the external cold air .

The main object of the present invention is to provide a kind of preheating thermometer capable of double heating from inside and outside. In addition to heating the inside of the front neck of the thermometer from the internal and external heating modules inside the thermometer, the external heating module of the heating case is used to heat the outside of the sensor head to achieve high-speed preheating. Therefore, even if the thermometer is taken out of the heating case, the heat energy is maintained by the heating module provided in the thermometer, and a rapid decrease in the temperature of the front neck of the thermometer can be avoided.

The preheating thermometer described above is preheated to the human body temperature (39 ° C or higher, preferably 42 ° C). When the thermometer is removed from the heating case, the temperature is lowered to the same level as the body temperature by cooling the air. The body temperature value is acquired in accordance with the set temperature rise or temperature fall time value range. Thereby, measurement time can be shortened and higher speed measurement can be performed.

When the preheating thermometer preheats the thermometer, it supplies electricity to the internal heating module of the thermometer and the external heating module of the heating case from an external power source or a large-capacity battery, and heats the front neck and the sensor head of the thermometer. When the temperature after heating reaches a set temperature value, a temperature signal is transmitted from the temperature measurement module of the thermometer to a control circuit provided in the heating case, and the electric supply and heating to the heating case are stopped. And when temperature falls to a preset value, it again heats by a signal to a heating case by the said means.

It is another object of the present invention to provide a kind of preheating type high-speed measuring thermometer having a function of using a normal thermometer even when the thermometer does not use the preheating function.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

The preheating type thermometer of the present invention shown in FIGS. 1 to 4 is mainly composed of a heating case 1 and a thermometer 2. Among them, the heating case 1 is connected to a power source. Furthermore, electricity may be provided from the large capacity battery 14 in the external power source 3 or the heating case 1. An accommodation groove 11 is provided in the heating case 1, and an external heating module 15 is attached to one end thereof. The external heating module 15 can provide a preheating temperature. A first joining member 12 is provided at the other end inside the housing groove 11, and a control circuit 13 is provided inside the heating case 1. The heating case 1 provides electricity to the external heating module 15 and the internal heating module 25 built in the front neck portion 211 of the thermometer 2 for heating.

The thermometer 2 is provided with a main body 21, a front neck portion 211, a display window 22, a sensor head 23, a second joining member 24, and an internal heating module 25. When the thermometer 2 is placed in the heating case 1, the sensor head 23 is accommodated in the accommodation groove 11 of the heating case 1 and is fixed near the external heating module 15. The second joining member 24 is electrically connected by insertion with the first joining member 12 of the heating case 1 and can transmit signals. At the time of temperature measurement, the temperature measurement module 26 built in the thermometer 2 controls an electric circuit and has a display and warning function.

With continued reference to FIGS. The thermometer 2 is provided with an internal heating module 25 inside the front neck portion 211 between the main body 21 and the sensor head 23, and a heating wire 24 a is provided between the internal heating module 25 and the second joining member 24. When the two joining members 24 and the first joining member 12 of the heating case 1 are electrically connected to each other, electricity is supplied to the internal heating module 25. In addition, an external heating module 15 is provided at one end of the housing groove 11 provided in the heating case 1, and the heating case 1 is connected to a power source. As the power source, a large capacity battery 14 may be provided inside the external power source 3 or the heating case 1. A control circuit 13 is provided inside the heating case 1. One end of the power source described above is directly connected to the control circuit 13, and the control circuit 13 is connected to the external heating module 15 via the power cord 131. The control circuit 13 is connected to the first joining member 12 via the heating wire 12 a and then connected to the internal heating module 25 of the thermometer 2 by the heating wire 24 a of the second joining member 24. Thereby, electricity can provide electric energy to the internal heating module 25 and the external heating module 15 via the control circuit 13.

The 2nd joining member 24 of the thermometer 2 and the 1st joining member 12 of the heating electric wire 1 have a signal connection mechanism besides having an electrical conduction mechanism. The electrical conduction mechanism includes when the first joining member 12 and the second joining member 24 including the conducting terminal 121 of the first joining member 12 and the conducting terminal 241 of the second joining member 24 are joined together. The two conduction terminals 121 and 241 are electrically connected to each other. The signal connection mechanism includes the signal terminal 122 of the first joining member 12 and the signal terminal 242 of the second joining member 24. After the first joining member 12 and the second joining member 24 are joined, the two signal terminals 122 and 242 are connected to each other and can transmit signals.

The temperature measurement module 26 of the thermometer 2 is connected between the sensor head 23 and the control circuit 13 of the heating case 1, and a signal transmission line 27 is provided between the sensor head 23 and the temperature measurement module 26. A temperature signal of the sensor head 23 is detected via the signal transmission line 27. Further, a signal transmission line 24b is provided between the temperature measurement module 26 of the thermometer 2 and the second joining member 24, and the control circuit 13 and the first joining member 12 are also provided with the signal transmission line 12b. The generated temperature signal is connected to the second joining member 24 and the first joining member 12 in contact with the second joining member 24 through the signal transmission line 24b, and then connected to the control circuit 13 through the signal transmission line 12b.

When the thermometer 2 is placed on the heating case 1, the second joining member 24 of the thermometer 2 and the first joining member 12 of the heating case 1 are inserted into each other, and electric energy is provided to the internal heating module 25 via the control circuit 13. Is done. When used, after starting, the external heating module 15 preheats the sensor head 23 of the thermometer 2 and the internal heating module 25 preheats the front neck 211 of the thermometer 2. Accordingly, the temperature signal of the sensor head 23 is detected from the temperature measurement module 26 and transmitted to the control circuit 13 inside the heating case 1 via the second joining member 24 and the first joining member 12. After detecting that the temperature of the thermometer 2 sensor head 23 has reached the set heating temperature (39 ° C. or higher, preferably 42 ° C.) from the control circuit 13, the control circuit 13 controls the electric supply to perform external heating. The heating of the module 15 and the internal heating module 25 is stopped. On the other hand, when it is detected by the control circuit 13 that the temperature of the thermometer 2 sensor head 23 is lower than the set heating temperature and is lowered to a certain temperature, electricity is provided again and the external heating module 15 and the internal heating are provided. The module 25 heats the sensor head 23 and the front neck 211 of the thermometer 2.

The present invention uses an external power source to heat the front neck portion 211 by the internal heating module 25 of the thermometer 2 and the sensor head 23 external portion by the external heating module 15 of the heating case 1. There is a preheating effect. Furthermore, by providing the internal heating module 25 inside the thermometer 2, even if the thermometer 2 is separated from the heating case 1, the temperature decrease is small due to the action of heat retention.

According to the experiment of the present inventor, when the thermometer 2 is preheated to 42 degrees Celsius and then the temperature is measured on the human body in a room temperature environment, the cooling action by the atmosphere is reduced to about 35 degrees Celsius to 37 degrees Celsius, Results close to temperature were obtained. When measuring, if the temperature rise or temperature drop does not exceed 0.1 degrees Celsius within the set time, the measurement can be completed. Since the temperature of the human body is not reduced by the endotherm by the thermometer, the measurement time is shortened and the dual effect of high-speed preheating and high-speed measurement is achieved.
