Abstract

PROBLEM TO BE SOLVED: To measure both a body temperature value and a pH value, by detecting a body temperature and displaying a value of the body temperature, and also detecting a pH of humor and displaying a value of the humor. SOLUTION: For example, when a temperature is to be measured in the mouth, a case body 1 is placed under the tongue, a body temperature is detected by a temperature-sensing part 2 and a value of the body temperature is displayed by an electronic circuit of a body temperature display part 3. When the case body 1 is put under the tongue, a pH of saliva as a humor is detected by a pH-measuring part 4 and a value of the pH is displayed by an electronic circuit of a pH display part 5. The body temperature value and pH value can be measured together without using a clinical thermometer and a pH meter separately. The clinical thermometer can be used in common to measure the body temperature and pH, thereby enhancing the use comfort.

[0002]

2. Description of the Related Art Conventionally, mercury thermometers, thermistor thermometers, thermocouple thermometers and the like have been known as this type of thermometer, and body temperature has been measured by axillary thermometry, oral thermometry, and rectal thermometry as measurement methods.

Here, the body temperature of the human body is usually kept constant at about 37 ° C., and by keeping the body temperature constant, the reaction rates of various chemical changes including enzyme action in the body are kept constant. Therefore, it can be said that measuring the body temperature is indispensable for health management of healthy people and disease management of patients.

[0004] This can be said about the pH value (hydrogen ion concentration) of body fluids such as saliva as well as the measurement of body temperature, and the pH value of this saliva can be measured in dentistry, gastroenterology, neonatology and psychiatry. Has been studied in the field.

[0005] It has been reported that the pH value of this saliva is generally high when awake, low during sleep, decreased under the influence of the general condition, especially the acidity of the esophagus and stomach, and increased by psychological load. , Artificial infants have a higher salivary pH than mothers
It is said that the value is reduced, and that it reflects the state of tooth decay and dental plaque, and there are unknown parts, but there is no objection that it can be used as an indicator of physical condition.

[0006]

However, the thermometer of the above-mentioned conventional structure is limited to only the measurement of body temperature, and in order to know the pH value, it is necessary to prepare a separate pH meter.
In addition, since medical procedures are involved, it is very troublesome, and the body temperature and the pH value may change every moment, and it may be necessary to know these values at the same time.

[0007]

The object of the present invention is to solve such inconveniences.
According to the first aspect of the present invention, there is provided a temperature sensing section for detecting a body temperature, a body temperature display section for displaying the body temperature value, and a p for detecting the pH of a body fluid.

Reference numeral 1 denotes a housing, which is a temperature-sensitive device for detecting the temperature of a human body at the tip of a housing 1 made of synthetic resin. A body temperature display unit 3 for displaying the body temperature value is provided on the surface of the housing 1.

As a structure of the temperature sensing part 2, a mercury thermometer is used, and the expansion and contraction action caused by the temperature change of the sealed mercury is utilized. A display element such as an EL display element is used, and the body temperature is displayed digitally by the body temperature display unit 3 in a measurement region of 35 ° C. to 42 ° C. The structure of the thermistor thermometer, thermocouple thermometer, or semiconductor sensor is not limited to the mercury method.

Reference numeral 4 denotes a pH measuring unit.
A special electrode made of a glass electrode or the like, which is disposed in the vicinity of the temperature sensing part 2 at the tip of the body, and is formed so that the temperature sensing part 2 and the pH measurement part 4 can be inserted and arranged in the oral cavity of a human body. By measuring the potential difference, the pH value as the hydrogen ion concentration of the bodily fluid is detected, and this pH value is converted into an electronic circuit using a display element such as a liquid crystal or an EL display element. Accordingly, since the normal value is about 7, the pH value is digitally displayed on the pH display unit 5 within the measurement range of pH 6.0 to pH 8.0. Note that a structure other than the method of measuring pH using a special electrode such as a glass electrode, for example, a semiconductor sensor may be employed.

Reference numeral 6 denotes a voice generating unit, which is configured to generate a voice such as "body temperature is 00 ° C." by the voice IC or the like.

In this case, a voice changeover switch 7 is provided to change the pH value to the generation of a body temperature value or alternately to the generation of a body temperature value to generate a voice such as "pH 00". It is configured to be.

Further, in this case, the body temperature value is digitally displayed in red by the body temperature display section 3 and the pH value is digitally displayed in green by the pH display section 5 so as to be displayed in mutually different colors.

In this case, a power switch 8 is provided in the housing 1, and a battery 9 as a power source for ICs and electronic circuits is built in.

Since this embodiment has the above configuration,
