Abstract
A thermometer has both infrared sensing unit and visible light sensing unit so it can detect out simultaneously the body temperature which is represented by infrared signal as well as the image which is for detection area with help of the visible light. Therefore it can judge whether the detected temperature is for correct position or not through the image as well as it can assist to judge state on detection area with help of the image of addition to obtain measured body temperature.
Description
Technical field
A kind of clinical thermometer of integrating the image demonstration, particularly a kind of receiving and analyzing infrared signal and visible light signal simultaneously, and then can see through the integration image demonstration clinical thermometer that visible image is assisted diagnosis.
Background technology
Because the electromagnetic wave that the body temperature temperature range of human body is given off mainly is to be positioned at ultrared scope, therefore by means of the electromagnetic wave of the described infrared spectral range of receiving and analyzing, just can be by the counter temperature of releasing human body of heat radiation.Particularly work as employed instrument and can accurately only sense a fraction of infrared signal delicately, and can extrapolate relative body temperature immediately.
Based on this notion, existing in recent years duct sonde-type clinical thermometer is pushed out and becomes hot product.By the detection mouth of duct probe is aimed at ear inside, just can detect the temperature in the ear.Particularly get final product owing to only receiving enough transducing signals, and do not need as known mercury clinical thermometer, when measuring, must there be a mercury clinical thermometer and measuring point to reach thermally equilibrated process, therefore Measuring Time shortens to less than finishing a second, and this is for measuring the active or sick more convenient practicality of child.Generally speaking, shown in Figure 1A, the duct sonde-type clinical thermometer of known technology comprises the two large divisions at least: infrared ray sensing device 11, in order to detect a plurality of infrared signals; And APU 12, in order to the described infrared signal of analyzing and processing.Certainly, look the different size of specific product, shown in Figure 1B, signal transmitting apparatus 13 (wired or wireless all can), supply unit 14, control interface device 15 etc. can also be arranged, and the device that can optionally select for use again.
In the prior art, for the existing many improvement of duct sonde-type clinical thermometer, for example better external form of grasping, sensitiveer infrared ray sensing device, shorter measurement time, power saving design of memory function, outage automatically automatically or the like.But, for the body temperature that whether can guarantee correctly to measure correct regional position, and for the clinical thermometer whether other informational function can also further be provided outside body temperature information is provided, also comparatively rare at present.
But, there is 5 percent infant that the existing picture of duct bending is arranged approximately according to statistics, error to some extent often when make measuring, promptly measure less than nervous centralis temperature that is positioned at ear inside or ear-drum temperature, particularly, even if duct does not have bending, only the existence of earwax or user's misoperation also may cause the incorrect of measurement result.Furtherly, because known duct sonde-type clinical thermometer can only be measured temperature, and can't see the ear internal state, even if the precision of measurement of infrared ray sensing device is risen near the temperature that can only measure in the infrared ray sensing device one cubic centimeter, the concrete position that also can't utilize so accurate infrared ray sensing device to find out ear inside is where inflammation, and can only detect the symptom that there is inflammation ear inside.
In sum, known duct sonde-type clinical thermometer still has the space that obviously can improve, is worth more research and development.
Summary of the invention
A fundamental purpose of the present invention is for providing a kind of clinical thermometer that image shows of integrating, and it is not directly to be exposed to extraneous clinical thermometer that a kind of ear position, position, oral cavity and throat position that is suitable for measuring human body or the like particularly is provided.
Another fundamental purpose of the present invention is for providing a kind of clinical thermometer that image shows of integrating, particularly provide a kind of both can detected temperatures and can obtain the clinical thermometer that the integration image of other message at measured temperature position shows.
Another fundamental purpose of the present invention sees through to receive simultaneously and handles infrared signal and visible light signal for a kind of clinical thermometer that image shows of integrating is provided, and improves the unavoidable many shortcomings of known duct sonde-type clinical thermometer.
A kind of clinical thermometer that image shows of integrating provided by the invention is characterized in that the clinical thermometer that this integration image shows comprises:
One light receiving trap is in order to receive a plurality of infrared signals and a plurality of visible light signal;
A pair of spectral separation device is in order to separate described infrared signal and described visible light signal;
One infrared ray sensing device is in order to detect described infrared signal; One transmission of visible light induction device, with described infrared ray sensing device for being arranged in parallel, in order to detect described visible light signal; And
One APU is in order to described infrared signal of analyzing and processing and described visible light signal.
The clinical thermometer that integration image proposed by the invention shows has infrared ray sensing device and transmission of visible light induction device basically simultaneously.Therefore, the present invention can detect the infrared signal of representing body temperature simultaneously, and the image of representing detected zone.By this, the present invention can also see through the temperature that image judges whether to detect the tram except obtaining the body temperature, and can see through the situation that image assists to judge detection zone.For instance, can see through image and judge that the integration image shows the position of the infra-red ray detection device of clinical thermometer, and then can judge the temperature (particularly when the enough sensitivities of infrared ray pick-up unit) at concrete position in the human organ; More can see through image simultaneously and assist to judge whether the symptom of the temperature representative that measures is positioned near the somewhere the measured zone.
Compared with prior art, the present invention has following advantage at least:
(1) while receiving and analyzing infrared ray and visible light provide dual message.Therefore, can avoid receiving only and analyze ultrared known technology, many disappearances of the unavoidable generation of institute.
(2), can judge the position of infrared ray sensing device through the use of visible light.By this, remove the body temperature to avoid not detecting correct position because of duct bending or misoperation.
(3) see through the use of visible light, can judge and integrate the part that clinical thermometer that image shows is being measured at present.By this, can when using sensitivity to reach high infrared ray sensing device, not only can measure the medial temperature in a position (as ear or oral cavity), can also measure the temperature distribution state in this position more further.
(4) because infrared ray sensing device and transmission of visible light induction device all are known commercialization technology, and separation visible light and infrared ray also are known commercial technologies.Therefore, the present invention can use known commercial technology and just can realize easily, is not have great technical difficulty also can not increase what cost as long as remarkable breakthrough, the present invention are arranged in abstracto.
(5) because visible light can obtain image, and accurate infrared ray sensing device also can obtain image (as some night vision goggles or thermal imagery instrument).Therefore, making the present invention can not be a clinical thermometer, and can also play the part of the function of endoscope partly, asoscope or the like.
(6) because the progress of transmission technology (no matter being wire transmission or wireless transmission), and the progress of storing technology.The present invention can also connect (or comprising) device in order to record, transmission and storage image, uses that temperature and image are all changed into electronic record, and helps the use of electronic case history or the like.
The present inventor at first points out different (or saying the biggest advantage of comparing down) of duct sonde-type clinical thermometer and known mercury formula clinical thermometer maximum, be that duct sonde-type clinical thermometer receives only the infrared signal that comes from the outside, and do not need as mercury formula clinical thermometer, to allow mercury and extraneous measuring point heat-shift, to reaching after the thermal equilibrium just energy measurement.In other words, duct sonde-type clinical thermometer biggest advantage is to receive only the thermal radiation signal, and does not react with the external world.Also therefore, any further improvement to duct sonde-type clinical thermometer, all should not change receive only signal and not with reaction (particularly not needing to reach thermal equilibrium) this principal character in the external world with the external world.
Say further, why duct sonde-type clinical thermometer of the present invention can have this principal character, be because duct sonde-type clinical thermometer receives the infrared signal of representing body temperature, and infrared signal is electromagnetic radiation, only depend on the ultrared body part of emission (certainly, duct sonde-type clinical thermometer can not go to heat the temperature that changes in the ear chamber).But further, the present invention particularly points out, and any electromagnetic radiation all has such characteristic, no matter be infrared ray, ultraviolet ray, microwave or even visible light.
Therefore, the present invention proposes a practice that solves the above-mentioned various defectives of known technology duct sonde-type clinical thermometer: except detecting infrared ray, also detect visible light simultaneously.These two all is electromagnetic radiation, and detection can be finished in moment, and can not produce what influence to the human body that will measure.Yet, when visible light is also detected, except the body temperature of infrared ray representative, the image of measured part can also be provided, and then provide and judge that clinical thermometer is to measure message where, significantly reduce because duct bending or earwax exist, and can not detect the error message of correct position body temperature.In addition, also can also see through the image of visible light, the further reference information (for example judging duct is where to have the redness of inflammation now to look like) at the measured position of diagnosis is provided.
Certainly, if the infrared ray sensing device that uses is enough sensitive, also is not only to read a temperature, but obtains a heat distribution image, and then more message is provided.Certainly, this moment image that visible light signal provided be still helpful because many messages beyond the temperature height can be provided, as earwax be dried be wet, be that what kind of measles or the like are arranged as the surface of the red and swollen part of inflammation.
Certainly, emphasis of the present invention is to be comprehensively to use infrared ray and visible light, obtains body temperature and image.As for, propagation of the details of sensing device, Signal Processing device, image and body temperature relevant information or the like all is further planning of the present invention, is not most crucial feature of the present invention.In other words, the breakthrough that focuses on idea of the present invention, be to be susceptible to " detect visible light and obtain image " and the practice be incorporated into known duct sonde-type clinical thermometer.Therefore, all known technologies, as transmission of visible light induction device and image processing technique or the like, the present invention can use, and makes the present invention on using, and does not have serious technical difficulty will overcome, or has serious cost to increase problem.
And, because the present invention has comprehensively used infrared ray and visible light, have no reason to limit the present invention as can be seen and can only be applied in the temperature of measuring ear.Such as tuck in down, strand ditch, oral cavity, nostril and anus or the like, all be the adaptable embodiment of the present invention.Certainly, can not disturbed, and in order to bring into play the advantage of using visible light, the present invention is specially adapted to measure the organ that oral cavity, nostril and anus or the like can directly measure people's body thin film tissue by human body skin for infrared ray can be measured effectively.

Certainly, be the influence of avoiding visible light and infrared ray to mix, shown in Fig. 2 E, present embodiment also is optionally to settle infrared ray filter disc 27 between infrared ray sensing device 21 and light entrance 20, and (or) between two spectral separation devices 32 (not shown in the figures, but can indirect reference Fig. 3 A or Fig. 3 B) and light entrance 20, optionally settle visible light filter disc 28.
Moreover present embodiment also can also allow APU 23, and optionally have following function: (1) enters battery saving mode after not using in a period of time automatically.For example with all sensing devices and all shutdown earlier of visible light source.(2) when detected temperature surpasses a predetermined value (as 38.5 ℃), just initiatively send caution sound and message.(3) initiatively do not carry out and extraneous transmission of getting in touch with, unless the user imports transfer instruction.
In addition, APU 23 can be one of following or its combination in any: microprocessor, digital signal processor, uC or uP.Transmitting device 26 can be one of following or its combination in any: infrared interface, microwave interface, Bluetooth transmission interface or generic serial port interface, and employed data formats can be NTSC, PLA or VGA.Display device 25 can be one of following or its combination in any: LCD screen or electricity slurry screen.
Another preferred embodiment of the present invention is a kind of clinical thermometer that image shows of integrating, and as shown in Figure 3A, comprises at least: light receiving trap 31, in order to detect a plurality of infrared signals and a plurality of visible light signal; Two spectral separation devices 32 are in order to separate described infrared signal and described visible light signal; Infrared ray sensing device 33 is in order to detect described infrared signal; Transmission of visible light induction device 34 is in order to detect described visible light signal; And APU 35, in order to described infrared signal of analyzing and processing and described visible light signal.Apparently, comparison diagram 3A and Fig. 2 A and Figure 1A, as can be seen the principal character of present embodiment be light receiving trap 31, two spectral separation device 32 and transmission of visible light induction device 34 threes, particularly light receiving trap 31 and two spectral separation device 32 the two.
Because the main difference point of present embodiment and last embodiment is to be light receiving trap 31 and two spectral separation devices 32, therefore will concentrate on light receiving trap 31 and two spectral separation devices 32 to the discussion of this embodiment subsequently, and omit other part identical with last embodiment.
In this embodiment, two spectral separation devices 32 can show the infrared ray of clinical thermometer and the device that visible light is separated with entering this integration image together for any.And because infrared ray is obviously different with wavelength of visible light, therefore any assembly that can separate the electromagnetic radiation of different wave length can be as two spectral separation devices 32.Generally speaking, two spectral separation devices 32 can be spectroscope, germanium window (germanium window) or silicon window (silicon window).
Further, shown in Fig. 3 B, two spectral separation devices 32 can another person be reflected by two spectral separation device 32 so that described infrared signal 301 and described visible light signal 302 1 penetrate two spectral separation devices 32.Certainly, shown in Fig. 3 C, two spectral separation devices 32 also can be to make described infrared signal 301 and described visible light signal 302 can both penetrate two spectral separation devices 32, but the two direction of propagation (or intensity) difference after penetrating.
Certainly, separate fully inadequately with infrared ray for avoiding two spectral separation devices 32 to separate visible light, shown in Fig. 3 D, present embodiment also is optionally to settle infrared ray filter disc 36 between two spectral separation devices 32 and infrared ray sensing device 33, and (or) between two spectral separation devices 32 and transmission of visible light induction device 34, optionally settle visible light filter disc 37.
The above is preferred embodiment of the present invention only, is not in order to limit claim of the present invention.Still can be simplified in the category that does not break away from flesh and blood of the present invention and implemented, these variations should still belong to scope of the present invention.Therefore, category of the present invention is defined by claim.
