  The present invention relates to a diseased body detection apparatus and a diseased body detection system that detect a diseased body that has developed a disease.

  2. Description of the Related Art Conventionally, a diagnostic apparatus for diagnosing the health condition of a subject by measuring body information such as body temperature of the subject such as a human being or an animal is known. In particular, in quarantine at airports, so-called pathogens such as SARS (Severe Acute Respiratory Syndrome) viruses, bacteria and protozoa (malaria parasites that cause malaria, trypanosomes that cause African sleeping sickness, etc.) In order to prevent accidents at the water's edge, it is necessary to quickly and easily diagnose the health status of travelers, etc., and there is an increasing demand for diagnostic devices that enable highly accurate diagnosis. Has been done.

  Here, if the traveler is infected with a pathogen, the temperature of the traveler is likely to become high. For this reason, as shown in Non-Patent Document 1, etc., as a technique related to a diagnostic device used at the time of quarantine, a so-called quarantine device, a thermograph that captures and displays an image of the temperature of the traveler, a so-called thermal image A technology is known to alert quarantine officers by sounding an alarm when a traveler passes through a quarantine booth. Moreover, when infected with a pathogen, in addition to the body temperature, for example, there is a high possibility that the heart rate, the respiratory rate, and the like become faster. Therefore, although it is not directly related to quarantine, as a technique relating to other diagnostic devices for diagnosing infections to pathogens by simply measuring body information other than body temperature of the subject, for example, the following patent document Techniques described in 1 and 2 are known.

Japanese Patent Laid-Open No. 2006-304963 as Patent Document 1 discloses a non-contact diagnostic apparatus (1-5) for enabling diagnosis even when a subject such as a human being is isolated and preventing secondary infection to a doctor or the like. The technology about is described. Patent Document 1 describes a technique for radiating a microwave toward a subject and diagnosing the heart rate of the subject based on a received reflected wave.

An electromagnetic wave transmission / reception sensor (11) that receives a reflected electromagnetic wave, and based on the received reflected electromagnetic wave, a physical condition detector (10) that detects a physical condition such as a heart rate and a respiratory rate of the subject. The technology is described. That is, in Patent Document 2, the movement of the body of the subject lying down by the bed (1), that is, so-called body movement is reduced and the body state is measured with high accuracy, and the electromagnetic wave transmission / reception sensor (11) A technique is described in which the physical condition is simply measured without bringing a measuring instrument or the like into contact with or closely contacting a subject.

JP 2006-304963 A (Abstract, “0006” to “0026”, FIGS. 1 to 7) JP 2000-102515 A (Abstract, “0010” to “0034”, FIGS. 1 to 4) “SARS countermeasure thermography”, “online”, September 9, 2003, NEC Sanei Co., Ltd., “Search December 18, 2007”, Internet <URL: http://www.necsan-ei.co.jp /general/th/application/sars/sars_information.pdf>

(Problems of conventional technology)
As in Non-Patent Document 1, in the technique of taking a thermal image of the body surface temperature of the traveler and measuring the body temperature of the traveler, for example, the body surface temperature is lowered due to sweating by the traveler. In this case, there is a problem that it is impossible to accurately determine that the traveler is infected with the pathogen because the quarantine booth can be passed without any problem.
Further, in the techniques of Non-Patent Document 1 and Patent Documents 1 and 2, since there are individual differences in the traveler, when diagnosing a health condition using only one body information such as body temperature, heart rate, and respiratory rate, The diagnosis result is dragged by the statistical value of the physical information, and the vague range between the case where the traveler is really infected with the pathogen and the case where the individual is merely individual difference cannot be determined. For this reason, there is a problem that it is impossible to accurately determine that the traveler is infected with the pathogen.

Also, for example, if a traveler is infected with Vibrio cholerae, the body temperature will not be high,
Rather, it becomes hypothermic, and in typhoid and the like, there is often a relatively bradycardia in which the rise in pulse is small compared to the rise in body temperature. Therefore, as in the techniques of Non-Patent Document 1 and Patent Documents 1 and 2, simply determining whether the body temperature is high fever or whether the heart rate is fast is transmitted to a pathogen. There has been a problem that it cannot be accurately determined whether or not it is.

(Experimental example)
Here, whether or not the subject is the diseased substance is determined based on the diseased substance detection value S (X ₁ , X ₂ , X ₃ ) of the diseased substance detection system S according to the first embodiment. The following experimental examples 1 and 2 were prepared in order to check whether or not can be accurately determined.

(Experimental example 1)
In Experimental Example 1, first, in the room provided with the diseased body detection system S of Example 1, the room temperature is maintained at 26.0 ± 1.0 ° C. and the humidity is maintained at 60% or less. And in Experimental example 1, about 20 test subjects A to T, the normal state (before load) which does not give exercise load is made into a normal group, and the state (after load) which gave exercise load is made a pseudo-pathogen. As the pseudo-infection group considered to have infected and fevered, the above-mentioned normal group and the pseudo-infection group were subjected to the above-described pathogen detection system S (see ST5 to ST12 in FIG. 5). .

  In Experimental Example 1, INFRA-EYE 1200 manufactured by Fujitsu Limited is used for the thermography device TG, and the respiratory rate measuring device RR and the heart rate measuring device CR are jointly used with Tau Giken Co., Ltd. The developed microwave radar was used. In Experimental Example 1, the exercise load on the subjects A to T is determined by an exercise electrocardiogram inspection apparatus, a so-called ergometer, that examines changes in the electrocardiogram when exercise load is applied by pedaling the same pedal as a bicycle. Giving. In Example 1, the subjects A to T were tested as healthy men with an age of 22 ± 0.97 years.

(Experimental result of Experimental Example 1)
FIG. 6 is an explanatory diagram of the prevalence and post-loading prevalence determination values of each subject in Experimental Example 1, and is an explanatory diagram of a graph with the prevalence detection value on the vertical axis and each subject on the horizontal axis. .
FIG. 7 is an explanatory diagram of body temperature area values before and after loading for each subject in Experimental Example 1.

As shown in FIG. 6, in Experimental Example 1, for the subjects A to E and G to T other than the subject F, the diseased body discriminating value Z (X ₁ , X ₂ , X ₃ ) of the normal group before the load is obtained. , Z _min ≦ Z (X ₁ , X ₂ , X ₃ ) ≦ Z _max (Z _min = 0.000, Z _max = 16,000), and the diseased body discrimination value Z of the pseudo-infection group after loading _{(X 1, X 2, X} 3) _{is, Z (X 1, X 2} , X 3) it can be seen that to meet the _{<Z min (Z min = 0.000} ). Therefore, in Experimental Example 1, for the subjects A to T, it is highly likely that the normal group before the load is not a diseased body based on the diseased body discrimination value Z (X ₁ , X ₂ , X ₃ ). It can be discriminated with accuracy, and it can be discriminated with high accuracy that the pseudo-infection group after loading is suspected of being a diseased body.

In Experimental Example 1, the simulated infection group is the subjects A to T who are given the exercise load by the ergometer. For this reason, the subjects A to T have a decrease in body surface temperature due to sweating, and as shown in FIG. 7, the body temperature area value X ₃ after loading is compared to the body temperature area value X ₃ before loading. You can see that it is getting smaller. Therefore, originally, in spite of the high heat infected etc. pathogens, even if the temperature area value is reduced by sweating or the like, the or respiration rate X _2, is calculated by the abnormal value of the heart rate X ₁ It can also be seen that it is possible to discriminate whether it is a normal group or a pseudo-infected group based on the diseased body discrimination value Z (X ₁ , X ₂ , X ₃ ).

(Experimental example 2)
In Experimental Example 2, first, in the room provided with the diseased body detection system S of Example 1, the room temperature is 25.4 ± 0.5 ° C., and the humidity is 52.3 ± 6.2% or less. Keep it in a safe state. And in Experimental example 2, the said sick body detection process (refer ST5-ST12 of FIG. 5) by the said sick body detection system S was performed with respect to 502 test subjects. Further, in Experimental Example 2, an inquiry for confirming whether or not the subject is actually the diseased body is performed on the subject suspected of the diseased body by the diseased body detection process, and the body temperature is measured by a thermometer. Remeasurement, respiratory rate and heart rate were remeasured by nurses.
Furthermore, in Experimental example 2, after each said subject turns into one's turn based on the total time until the said sick body detection process is complete | finished with respect to all the said test subjects, before the said physical measurement apparatus U The average time from moving to the measurement position, ending the diseased body detection process and leaving the measurement position was calculated.

  In Experimental Example 2, IS-7800 manufactured by NEC Sanei Co., Ltd. is used for the thermography device TG, and the respiration rate measuring device RR and the heart rate measuring device CR are the same as those in Experimental Example 1. A microwave radar was used. Moreover, in Example 1, about the test subject's sex, age, health condition, etc., it experimented at random.

(Experimental result of Experimental Example 2)
FIG. 8 is an explanatory diagram of the experimental results of Experimental Example 2, and is an explanatory diagram of actual measured values of the sex, age, body temperature, pulse rate, and respiratory rate of each subject determined to be suspected of having a disease.
In Experimental Example 2, it was determined that 6 subjects out of 502 subjects were suspected of having a disease. Moreover, as shown in FIG. 8, it turns out that all the 6 test subjects determined to be suspected of the above-mentioned diseased body have a slight fever of 37 ° C. Further, in FIG. 8, it is found that a 26-year-old woman who was first determined to be a morbid patient has reported that he / she has a subjective symptom such as a headache and is cold in the interview. It was. Therefore, in Experimental Example 2, it can be seen that a subject who is actually highly likely to be a morbid body can be determined based on the morbid body determination value Z (X ₁ , X ₂ , X ₃ ).

  Moreover, in Experimental example 2, after each said test subject becomes his turn, the said average time until it moves to the said measurement position, complete | finishes the said sick body detection process, and leaves the said measurement position is 9. It was found to be 27 [sec]. The average time (9.27 [sec]) is all the time necessary for the examination, including the physical information measurement time T0 (5.0 [sec]). Therefore, it can be seen that a large number of subjects can be inspected in a short time compared to an inspection or the like in which the subject lies on a bed or an electrode or a sensor needs to be attached to the subject.

As a result, the diseased body detection system S of Example 1 determines whether the subject is a diseased body that has developed a disease based on the diseased body discrimination value Z (X ₁ , X ₂ , X ₃ ). Can be determined with high accuracy.
Further, the diseased body detection system S according to the first embodiment is configured such that the thermography device TG and the physical information measurement device U including the respiratory rate measurement device RR and the heart rate measurement device CR are applied to the subject.
