Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin temperature measuring device for a fingertip and a skin temperature measuring method.

[0002]

2. Description of the Related Art It is known that vibration of a finger or fingers is caused by the use of a vibration machine such as a chain saw, a pitching hammer, a brush cutter, various keyboards, motorcycles or the like. The vibration disorder appears as a blood circulation disorder of the fingertip, and the blood circulation disorder appears as an abnormal skin temperature of the fingertip. In treating a patient suffering from such a blood circulation disorder, it is first necessary to diagnose the presence or absence of the blood circulation disorder and its degree.

As a device for measuring the skin temperature of the fingertip portion, Japanese Patent Laid-Open No.
The ones described in Japanese Patent Publication No. 1-234839 (Japanese Patent Publication No. 5-15454) and Japanese Patent Laid-Open No. 4-8346 are proposed. The former one, as shown in FIG.
The skin temperature is measured by the non-contact type thermometer 4 while inserting a hand into a low temperature constant temperature bath 2 equipped with a cooler 31 (reference numeral is the same as the above, hereinafter the same) and applying a cooling load to the fingertip portion f. The presence or absence of blood circulation disorder is determined based on the measurement results shown in FIG. 7 (b). In the latter case, the skin temperature of the fingertip is measured while applying a cooling load by the same means.

[0004]

In order to strictly determine the presence or absence of blood circulation disorder, as many fingers as possible among the total of 10 fingers of the left and right hands, especially the middle finger and the index finger, which tend to cause blood circulation disorder, It is desirable to measure the skin temperature of the fingertips for a total of 6 fingers on the left and right of the ring finger. However, it takes a considerable amount of time to measure the skin temperature (see FIG. 7 (b) above).
It takes about 7 minutes in the example shown in FIG. 6 and 20 minutes or more in the example shown in FIG. 6 of the latter publication). Time (7 minutes × 6 (book) = 42 in the example of FIG. 7 (b) above)
Minutes, in the latter example, 20 minutes x 6 (books) = 120 minutes)
Will be required.

Further, such skin temperature measurement is carried out by a group medical examination for a group of workers such as a forest worker who uses a chain saw, a civil engineer who uses a pitching hammer, and a mailman who uses a motorcycle. Considering that in many cases, it is a very serious problem in terms of measurement efficiency that one measurement target person requires a long measurement time as described above.

[0006] By the way, although there are no reliable data at present, the incidence of blood circulation disorder (how many persons are present in 100 measurement subjects) is not so high.

Therefore, the present invention has been made in consideration of the above circumstances, and it is possible to substantially shorten the time required for measuring the skin temperature of the fingertip portion by substantially measuring the skin temperature of the fingertip portion. An object of the present invention is to provide a device and a skin temperature measuring method.

[0008]

To this end, the present invention comprises a first skin temperature measuring unit A and a second skin temperature measuring unit B for measuring the skin temperature of the fingertip f. ing. The first skin temperature measuring unit A is composed of a non-contact type thermometer 51 that measures the skin temperature of a plurality of fingertips f at room temperature. In addition, the second skin temperature measuring unit B is installed in the thermostatic chamber 1
The constant temperature bath 1 is composed of the insertion part 16 of the fingertip part f.
A non-contact thermometer 15 for measuring the skin temperature of the finger tip f inserted from the insertion section 16; and a positioning section 17 for positioning the finger tip f in the visual field of the non-contact thermometer 15. ,
And a cooler 26 for cooling the inside thereof.

[0009]

According to the above construction, first, at room temperature, the first
The skin fluff temperature measurement unit A of FIG. 3 easily measures the skin fluff temperatures of the fingertips f of a plurality of fingers in a short time. While the second skin temperature measuring unit B applies a cooling load to the fingertip portion f having a relatively low skin temperature in the measurement by the first skin temperature measuring unit A, a sufficient time is taken. Measure the temperature change over time. Therefore, the fingertip portion f that takes sufficient time to measure the skin temperature while applying the cooling load may be the minimum necessary amount, and as a whole, the measurement time can be substantially shortened.

Next, the second skin temperature measuring unit will be described. FIG. 3 is a sectional perspective view of the second skin temperature measuring unit, and FIG. 4 is a sectional view of the same. The second skin temperature measuring unit B is the same as that shown in FIGS. 1 and 2 of the above-mentioned Japanese Patent Laid-Open No. 4-8346 and will be briefly described below.

Reference numeral 1 denotes a box-shaped low-temperature thermostatic bath. The thermostatic bath 1 is constructed by mounting a cover plate 3 on the outside of a heat insulating material 2 made of foamed synthetic resin or the like. The constant temperature bath 1 has a partition wall 5.
Is divided into a front side measurement chamber 6 for measuring the skin temperature and a rear side air conditioning chamber 7, and an air inlet 8 and an outlet 9 are opened at one upper side and one lower side of the partition wall 5. , And fans 11 and 12 are provided respectively.

Reference numeral 15 is a radiation thermometer as a non-contact type thermometer disposed in the lower part of the measuring chamber 6. 16 is the measurement room 6
1 is an insertion portion of a hand opened to a side wall portion of the cover member, and is made of a tongue-shaped elastic sheet for maintaining airtightness.
9 is attached. Reference numeral 17 is a box-shaped hand positioning portion provided in the measurement chamber 6 so as to communicate with the insertion portion 16, and is formed of a heat insulating elastic material such as sponge or foamed resin. Reference numeral 21 is a peep part provided on one side of the positioning part 17. As shown in the figure, when the hand is inserted from the insertion portion 16 into the positioning portion 17, in that state, the fingertip portion f
Is fixed within the field of view of the radiation thermometer 15. Reference numeral 24 denotes a peep window for peeking inside the constant temperature bath 1, which is provided immediately above the peep portion 21 and monitors whether or not the finger tip f is correctly positioned within the visual field of the radiation thermometer 15. .

In FIG. 4, reference numeral 13 is a partition wall which divides the air-conditioning chamber 7 into upper and lower parts, and a cooling device 26 is disposed below the partition wall. Reference numeral 14 is a vent hole, and 27 is a fan. The air sent from the inlet 8 to the upper part of the air-conditioning chamber 7 by the fan 11 is sent downward by the fan 27 through the ventilation holes 14 and cooled by the cooling device 26, and then the fan 12 makes the outlet 9 from the measurement chamber. It is sent to 6 as cold air. The temperature in the constant temperature bath 1 is set to an arbitrary temperature between 0 ° C and 7 ° C.

In FIG. 3, 30 is a nozzle and 31 is a fan. By this fan 31, the cool air sent from the outlet 9 is sucked into the nozzle 30, and the cool air is blown to the fingertip portion f from the air outlet 30a at the upper end thereof. By blowing cool air on the fingertip f in this manner, it is possible to prevent the air on the surface of the fingertip f from being stagnant and causing an error in measuring the skin temperature.
Reference numeral 32 denotes a temperature measuring device provided at the tip of the nozzle 30 for measuring the ambient temperature near the fingertip f in the measuring chamber 6.

The device for measuring skin temperature of the fingertip is composed of the first skin temperature measuring unit A and the second skin temperature measuring unit B as described above. B
The method for measuring the skin temperature using the method will be described. First, as shown in FIGS. 1 and 2, the first skin temperature measuring unit A measures the skin temperature at room temperature. The fingers to be measured by the first skin temperature measuring unit A include as many fingers as possible out of a total of 10 fingers of the right hand and the left hand, especially the middle finger, index finger, and ring finger, which are liable to cause blood circulation disorder. There are six. Of course, the measurement may be performed for all 10 fingers, or may be performed only for the finger having a higher possibility of blood circulation disorder, and the finger to be measured can be freely determined.

The temperature measurement of a plurality of fingers by the first skin temperature measuring unit A can be easily performed at room temperature in a short time. FIG. 5 shows an example of this measurement result.
In this example, the left and right hands each measure three fingers, for a total of six fingers. In the figure, a, b, c, d, e,
f is the measurement result of the left index finger, the left middle finger, the left ring finger, the right index finger, the right middle finger, and the right ring finger, respectively.

In the present example, the temperatures of the left middle finger and the right index finger are relatively much lower than the temperatures of the other fingers. Therefore, if the subject has a blood circulation disorder, it can be considered that the medical condition is prominently displayed on the left middle finger and the right index finger.

Then, next, the second skin temperature measuring unit B
As a result, with respect to the left middle finger and the right forefinger whose skin temperature is relatively low in the measurement by the first skin temperature measuring unit A, it is possible to accurately measure the temperature change (temperature profile) of the skin temperature over a sufficient time. I do. This measuring method is the same as the method described in JP-A-4-8346. That is, as shown in FIG. 3, a low temperature constant temperature bath 1
A hand is inserted inside, and the fingertip portion f is positioned within the visual field of the radiation thermometer 15 by the positioning portion 17. The inside of the constant temperature bath 1 is kept at a low temperature (5 ° C. in this embodiment), the ambient temperature near the fingertip f is measured by the temperature measuring device 32, and the set temperature is maintained, while the radiation temperature is maintained. The temperature change of the skin temperature of the fingertip portion f is measured by the total 15. In this case, as described above, the fan 31 is driven to drive the nozzle 30 to move the finger tip portion f.
It is desirable to blow cool air to the air so that the air near the fingertip portion f does not stagnant.

FIG. 6 shows the temperature profile of skin temperature measured in this way. The solid line is the curve of a healthy person and the broken line is the curve of a person with peripheral circulatory dysfunction. The measurement time is about 25 minutes. As described in the above-mentioned Kaihei 4-8346, in the case of a healthy person, even if the skin temperature of the fingertip f falls to a certain temperature, due to the cold vasodilation reaction of the peripheral circulatory system, to a certain temperature. Rise again. On the other hand, in the case of a handicapped person, the skin temperature begins to drop rapidly at the same time when the operator puts his / her hand into the constant temperature bath 1, and after 10 minutes, the constant temperature bath 1
To about room temperature (5 ° C). That is, in the case of a disabled person, the cold vasodilation reaction as described above is not observed, and the skin temperature of the once lowered fingertip portion f does not rise. Thus, according to the presence or absence of the cold vasodilation reaction, it is easy to distinguish a healthy person from a person with peripheral circulatory dysfunction.

Therefore, if the temperature profile shown by the solid line in FIG. 6 is obtained for the left middle finger and the right forefinger, it is judged to be healthy (no blood circulation disorder), and the temperature profile shown by the broken line is obtained. If so, it is determined that there is a blood circulation disorder.

As described above, in the present means, first, the skin temperature of the fingertips of as many fingers as possible is measured easily in a short time by the first skin temperature measuring unit A (that is, rough measurement is performed). ), A finger having a relatively low skin temperature (that is, a finger having a high possibility of blood circulation disorder) is extracted from among them, and a sufficient measurement time is measured by the second skin temperature measuring unit B only for that finger. While applying, precise skin temperature measurement (that is, precise measurement) is performed. Therefore, unlike the conventional example, it is not necessary to perform precise skin temperature measurement for all fingers while applying a cooling load for a long time, so that the measurement time can be substantially shortened.

[0024]

As described above, according to the present invention, the first skin temperature measuring unit A and the second skin temperature measuring unit B are constituted, and the simple skin temperature measuring unit A is used for the simple skin temperature measurement. A finger having a relatively low skin temperature is extracted by measuring the temperature of the skin, and only for the finger, the second skin temperature measuring unit B applies a cooling load, and the temperature change of the skin temperature takes a sufficient time. Since the measurement is performed accurately, the measurement time can be substantially shortened, and in particular, group medical examinations of forest workers, civil engineering workers, postal workers, etc. can be performed quickly and quickly. be able to.
