Description

  The present invention relates to an electronic thermometer with a built-in wireless transmission / reception function.

  A thermometer is a jig that can be easily carried anywhere to measure body temperature, which is an important basic index for grasping the occurrence of abnormalities and state changes in the body, by a simple operation. Conventionally, mercury thermometers have been used as thermometers, but electronic thermometers have recently been used. Electronic thermometers generally incorporate a temperature sensor in the probe at the tip, and digitally display the body temperature of the patient or the like sensed by this temperature sensor using a liquid crystal display. Similar to the mercury thermometer, the electronic thermometer measures the patient's body temperature by applying a probe to the armpit or the anal cavity where the body temperature is relatively stable. The electronic thermometer has features such as easy handling, temperature measurement in a short time, and large and easy-to-read display. (For example, see Patent Document 1)

  As for the electronic thermometer, an ear thermometer is also provided that detects the temperature in the ear canal close to the hypothalamus, which controls the body temperature of the brain. Since the ear-type thermometer detects infrared rays radiated from the eardrum in the ear with a sensor provided in the probe, the temperature measurement operation can be performed in about one second.

  By the way, with the increase in health management orientation, continuous management such as body temperature, which is greatly useful as a basic material, is being carried out at the personal use level. The body temperature varies depending on, for example, individual differences, temperature detection location, temperature detection time or temperature detection method, etc., and therefore it is indispensable to continuously perform temperature measurement under the same conditions and grasp the average value data.

  Electronic thermometers are used together with mercury thermometers as jigs for body temperature measurement, but in the past, they were only used to temporarily measure body temperature, depending on the temperature reading based on the temperature displayed on the liquid crystal display. The reset operation was performed after checking the body temperature. Therefore, the electronic thermometer has been used as a jig for reading the numbers displayed on the liquid crystal display and writing them in a summary table or the like when the body temperature is continuously managed.

  In hospitals and the like, a temperature sensor is provided for each bed, and a system for transmitting temperature data of a patient measured by the temperature sensor to a management computer installed in a nurse center by wire or the like is also constructed. However, such a thermometer system requires a large-scale investment and targets only a specific patient, and a thermometer that is easily carried for personal use is not used as a thermometer sensor. Further, such a temperature measurement system is a one-way transmission system that transmits temperature measurement data to a management computer, and is not constructed as a bidirectional transmission / reception system that obtains information from the management computer side.

  Accordingly, the present invention provides an electronic thermometer that is used in the same manner of use as in the prior art to measure body temperature, and that the aggregation processing of the measured body temperature value data is simplified so that it can be used more effectively. With the goal.

An electronic thermometer according to the present invention that achieves the above-described object includes a temperature measuring unit that detects a body temperature, and a control unit that performs predetermined processing on body temperature value data output from the temperature measuring unit and outputs a control signal to each unit. And a liquid crystal display for displaying a body temperature value by an output from the control unit based on the body temperature value data, and a wireless transmission / reception module controlled by the control unit. The electronic thermometer displays the temperature value measured by the temperature measuring unit on a liquid crystal display, and transmits it to a personal computer wirelessly via a wireless transmission / reception module such as a Bluetooth module. Data processing such as conversion is performed.

  In addition, the electronic thermometer includes an internal memory for storing body temperature value data, and the body temperature value data can be called from the internal memory and displayed on the liquid crystal display as necessary. Therefore, in the electronic thermometer, not only the temperature is detected only once, but also the temperature data stored in the internal memory can be used, so that effective health management is practiced by a simple device. Like that.

  Further, the electronic thermometer reads the body temperature value data stored in the internal memory based on an instruction from a personal computer wirelessly connected via the wireless transmission / reception module, and transmits it to the personal computer via the wireless transmission / reception module. The electronic thermometer receives the determination result information of the body temperature value data that is executed in the personal computer and wirelessly output by the wireless transmission / reception module, and displays it on the liquid crystal display through the control unit. Therefore, the electronic thermometer is not limited to the conventional mere temperature measuring jig, but can also practice effective health management and medical guidance based on body temperature data with a personal computer.

  According to the electronic thermometer according to the present invention configured as described above, it is a small and inexpensive device that is used in the same manner of use as before and detects the temperature and displays the temperature measurement result on the liquid crystal display. It can be used easily without deteriorating the selfishness. According to the electronic thermometer, it has a wireless function to send the measured temperature data to the personal computer.
