Description

584720 V. Description of the invention (1) 1. [Technical field to which the invention belongs] A thermometer with integrated image display, especially an integrated image display thermometer that can receive and analyze infrared signals and visible light signals at the same time, and can assist diagnosis through visible images . 2. [Previous Technology]

Since the electromagnetic waves radiated by the human body's temperature range are mainly in the infrared range, by analyzing the electromagnetic waves in these infrared regions, the temperature of the human body can be deduced from the thermal radiation. Especially when the instruments can make sense only for precisely sensitive to a small part of the infrared signal, and immediately calculate the relative body temperature. This is based on a popular business can detect the sense signal to mercury body temperature less than a second, the second with two major parts such as signal; and a number. Of course, there can be two concepts of signal control interface. In recent years, ear thermometer thermometers have been introduced and manufactured. By aligning the detection port of the ear temperature with the inside of the ear, the temperature inside the ear is reduced. In particular, since only needs to receive enough, without the need of conventional mercury thermometers such as the measurement site must wait for the count to reach thermal equilibrium, and therefore the measuring time can be measured for restless children or sick is convenient. Generally, as shown in Figure A, the ear thermometer of the conventional technology includes at least an infrared sensing device 11 for detecting a plurality of infrared analysis and processing devices 12 for analyzing and processing these infrared signals. Different specifications, as shown in the first B diagram, also transmit the device 1 3 (either wired or wireless), the power supply device 14, the device 15 and so on, which can be selected as needed.

Page 4 584720 V. Description of the invention (2) The conventional technology has many improvements to the ear thermometer thermometer, such as a better grasp of the appearance, a more sensitive infrared sensor, a shorter measurement time, Automatic memory function, power saving design with automatic power off, etc. However, whether the measure to ensure the correct temperature right area, and still be able to further provide other messages in the message provided outside temperature, but less relevant improvements.

However, according to statistics, about five percent of the infants had bent the ear canal is like that more often than not when measuring the temperature or the amount of the central nervous eardrum is located in the inner ear, and some errors. In particular, even if the canal is not bent, or just the user of improper operation of earwax may also lead to incorrect measurements. Further, since the conventional ear thermometer thermometer can only see the sensed temperature condition of the internal ear, it can be measured even if the precision of the infrared sensor can be raised to the vicinity of the infrared sensor to measure a cc The temperature inside can't use such a precise infrared sensor to find out where the inside of the ear is inflamed, but can only detect the symptoms of inflammation in the ear. In summary, there is still room for improvement in the ear thermometer with a conventional ear thermometer, which deserves more research and development. 3. [Summary of the Invention] One of the main objectives of the present invention is to provide a body temperature with integrated image display-584720 5. Description of the Invention (3) Gauge, in particular, to provide a suitable measurement of the ear, mouth and throat of the human body Wait, not a thermometer directly exposed to the outside world. Thermometer Another principal object of the present invention to provide an integrated body thermometer image display, in particular, to provide a temperature detecting both messages but can obtain other parts of the measured temperature of the good integration of the video display. Another main object of the present invention is to provide a thermometer with integrated image display, which can improve many shortcomings unavoidable by the conventional ear thermometer type thermometer by receiving and processing infrared signals and visible light signals simultaneously. The present invention proposes the integration of the video display of the thermometer, while having substantially the infrared and visible light sensing means sensing device. Accordingly, the present invention can simultaneously detect the number representative of the temperature of the infrared signal, and represents the detected image area. Accordingly, the present invention can be obtained in addition to the temperature, but also can determine whether transmission image detected temperature to the correct position, and to assist in determining the state of transmission image detection region. For example, you can use the image to determine the position of the infrared detection device integrated with the image display thermometer, and then determine whether the temperature in a certain part of the ear is detected (especially when the infrared detection device is sensitive enough); more Use the image to help determine whether the symptoms represented by the measured temperature are somewhere near the measurement area. (Learning the same) and (1 point of excellence) have less weight than clear hair compared to the technical information of the double. When the supply and extraction can be seen when it can be received with off-line red analysis,

Page 6 584720 V. Description of the Invention (4) Information. Thus, to avoid missing only receives infrared analysis of many conventional techniques, the resulting free difficult. (2) through the use of visible light, based on the position of the infrared sensor. Whereby, in addition to avoid bending the ear canal due to improper operation or does not detect the correct part of the body temperature.

(3) Through the use of visible light, you can determine the part of the thermometer that is currently being measured by the integrated image display. Accordingly, it may be when a high enough sensitivity infrared sensor, may only amount to a site (e.g., ear or buccal), the average temperature may also be measured to further distribution of the temperature inside this area. (4) Since the infrared sensor and the visible light sensor are both conventional commercial technologies, and the separation of visible light and infrared is also a conventional commercial technology. Accordingly, the present invention can be applied to conventional commercial technology can be easily achieved, as long as there is significant breakthrough in concept, the present invention is not much technical difficulties will not be much of the cost increase. (5) Images can be obtained due to visible light, and images can also be obtained by sophisticated infrared sensors (such as some night vision goggles or thermal imagers). Accordingly, the present invention may be not only a thermometer, and may also play a part of the endoscope, the function of the nose and the like.

(6) Due to advances in transmission technology (either wired transmission or wireless transmission), and storage technology advances. The present invention may also be coupled to (or contains) means for recording, transmission and storage of images, whereby the temperature and shadow image are converted into electronic files, and facilitate the use of electronic medical records and the like.

Page 7 584720 V. Description of the invention (5) IV. [Embodiments] Some embodiments of the present invention will be described in detail as follows. However, in addition to the detailed description, the present invention can be widely implemented in embodiments other cases. That is, the scope of the present invention is not restricted in this case, proposed embodiments, but should be made to the scope of the patent, whichever later.

The inventor of the present invention first pointed out that the biggest difference between the ear thermometer type thermometer and the conventional mercury type thermometer (or the biggest advantage in comparison) is that the ear thermometer type thermometer only receives infrared signals from the outside without the need for Like mercury thermometers, mercury exchanges heat with outside worlds and can only be measured after thermal equilibrium is reached. In other words, the biggest advantage of the ear type thermometer is just grab the temperature receives heat radiation signal, without reacting with the outside world. Therefore, any further improvement of the ear thermometer type thermometer should not change the main characteristic of π that only receives signals without reacting with the outside world (especially without the need to reach thermal equilibrium with the outside world).

Further, the inventor of the present invention directly pointed out that the ear thermometer type thermometer can have this main feature 'because the ear thermometer type thermometer receives the infrared signal representing the body temperature, and the infrared signal is electromagnetic radiation, which depends only on the emission Only infrared body parts (of course, ear thermometer thermometers cannot be heated to change the temperature in the ear cavity). However, further, the inventors of the present invention is particularly pointed out, any electromagnetic radiation has such a characteristic, whether it is infrared, ultraviolet, visible light or even microwaves.

Page 8 584720 V. INTRODUCTION OF THE INVENTION Therefore, the thermometer can be detected at the same time. However, when the amount can be increased there, it cannot be detected. Neither visible light is also available for the measured information. To the correct part, provide information about where the invention is missing. Both of them greatly reduce the temperature of the part to be detected. The method of diagnosing body temperature is proposed by the inflamed person. In the case of people with electric power, in addition to the image, less redness and swelling due to the error of the measurement department: In addition to detecting magnetic radiation, infrared detection is generated at the detection site to provide ear or ear canal curvature. In addition, there are further appearances). Knowing the technology ear temperature grabs the infrared, but also measures how much the effects can be instantaneous. In addition to the body temperature of the watch, the broken thermometer is used to measure the presence of cerumen, but it can also be used for reference (for example, if the infrared sensor used is sensitive enough, it can also not only read out a temperature, but obtain a thermal distribution image, and then Provide more information. Of course, the image provided by the visible light signal is still very helpful at this time, because it can provide a lot of information except the temperature, such as the earwax is dry or wet, such as the surface of the inflamed red swelling Rashes and more

Of course, the focus of the present invention is to use infrared and visible light in combination to obtain body temperature and images. As for the details of the sensor, the signal processing device, the dissemination of information related to images and body temperature, etc., are only further standardization of the present invention, and are not the core features of the present invention. In other words, the focus of the present invention lies in the breakthrough of ideas, and the idea of integrating the method of “detecting visible light to obtain an image π” into a conventional ear thermometer type thermometer. Therefore, all

Page 9 584720 V. Description of the invention (8) is used to form an infrared daylight (or heat distribution picture). Generally, the infrared sensing device 21 is basically an infrared temperature sensor, and the visible light sensing device 22 can basically be a charge coupled device sensor (CCD sensor) or a complementary metal-oxide sensor. Transistor detector (complementary metal oxide sensor, CMOS sensor) ° In this embodiment, visible light 1 is the light that enters from the outside! Sensitive), or it can be input from the outside during the measurement. In this case, as shown in Figure 2B, it can also be a light source (such as a fluorescent lamp in a diagnosis room). Details, but in general, to ensure that 4 is the highlight attached to the thermometer & ^ light 0 "so that the measured area (such as the ear) is the original L (if the visible light sensing device 22 is sufficient for external input light. However, if the visible light source 24 is attached to this embodiment, any visible light used in the present embodiment does not need to be limited to these. For illumination, the visible light source 24 is usually a light diode, a tungsten light bulb or a cold fluorescent

In this embodiment, you can also see the daylight signal of the optical signal, and transmit these infrared signals by wire and these can reach the outside world. However, it shows that the transmission mode of the wireless transmission mode and the wireless transmission mode can also coexist. . Both transmission devices 26 can be separated

Generally, double spectral separation device 32 may be a dichroic mirror, a germanium window (germanium window) or a window Xi stone (silicon window). Further, as shown in FIG III B, double spectral separation device 32 may be such that the infrared signals 301 and 302 of these visible signals based one, but the other 32 penetrating the spectral separation means is a double-bis spectrum separation means 32 is reflected.
