(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a skin temperature measuring device according to the present invention. Reference numeral 1 denotes a substantially cup-shaped container body made of a soft material such as elastic synthetic resin or rubber so that its opening 1a can be brought into close contact with the skin surface of the human body. 2 is a radiation thermometer as a non-contact type thermometer connected to the upper part of the device 1, and as shown in FIG. It measures the skin temperature inside the body 1, and its field of view is directed toward the opening 1a of the body 1. 3 is a condensing lens. 4 is a temperature converter connected to the radiation thermometer 2, and 5 is a recorder connected to the temperature converter 4, which records the skin temperature measured by the radiation thermometer 2 on its recording paper 6. .

Reference numeral 7 denotes a constant temperature gas bath as a constant temperature gas generating section, which is connected to the vessel 1 via an air supply tube 8 as an air supply section and an exhaust tube 9 as an exhaust section. The inside of this gas constant temperature bath 7 is maintained at a constant temperature of relatively high or relatively low temperature, for example, between 30°C and 45°C or between -5°C and 15°C.
Note that as the gas, a gas that is harmless to the body, such as air, is used.

The tips 8a and 9a of both tubes 8 and 9 are connected to the vessel body 1.
The gas at a predetermined temperature sent from the gas constant temperature bath 7 is sent into the vessel 1 from the tube tip 8a, and is further sucked in from the tube tip 9a and refluxed to the gas constant temperature bath 7. It's becoming like that. 10 is an intake pump. The radiation thermometer 2, temperature converter 4, recorder 5, and gas constant temperature bath 7 are well known.

This device has the above-mentioned configuration, and the method of using this device will be explained next.

The inside of the gas constant temperature bath 7 is maintained at a low temperature (for example, 5° C.), the opening 1a of the container 1 is pressed against the skin surface A of the body (for example, the shoulder or waist), and the pump 10 is driven. Then, the gas in the gas constant temperature chamber 7 flows into the tube 8.
It is sent into the vessel body 1 through the tube 9.
The gas is refluxed into the constant temperature bath 1 through. The inside of the container 1 is maintained at a substantially constant temperature (approximately 5° C. in this embodiment), and the skin temperature at the ambient temperature is measured by the radiation thermometer 2 and recorded on the recording paper 6. By pressing the container 1 against the skin surface A in this way, the inside of the container 1 becomes a space isolated from the outside, and the skin temperature can be accurately measured without being affected by the environmental temperature or the presence or absence of the surrounding air volume. Can be measured.

Figure 3a shows the temperature characteristic curve of the skin temperature measured when the skin is subjected to a cooling load of cold air. gradually descends,
The figure shows how the ambient temperature approaches 5°C after about 4 minutes. FIG. 3b shows a temperature curve when the pump 10 is stopped driving and the cooling load is released approximately 4 minutes after the cooling load is applied as described above, and the skin temperature is the initial temperature ( 35℃).

Furthermore, Fig. 4a shows a temperature characteristic curve of skin temperature measured when the inside of the gas constant temperature bath 7 is maintained at a high temperature (for example, 40°C) and a high temperature load is applied to the skin in the same manner as above. The skin temperature is the initial temperature (35
℃) gradually approaches the ambient temperature (40℃). Moreover, FIG. 4b shows the temperature characteristics when the high temperature load is stopped after about 2 minutes, and when the high temperature load is canceled, the skin temperature gradually approaches the initial temperature (35° C.).

By measuring the temperature characteristics when a cooling load or a high temperature load is applied to the skin in this manner, or when these are canceled midway through, it is possible to know whether there is an abnormality in the skin temperature.

FIG. 5 and FIG. 6 show another embodiment of the present invention, in which 7 is a high temperature gas constant temperature bath, and 11 is a low temperature gas constant temperature bath. This gas constant temperature bath 11
It is also connected to the vessel body 1 via an air supply tube 12 and an exhaust tube 13, and high temperature or low temperature gas is fed into the vessel body 1 from both thermostats 7 and 11 through tubes 8 and 12. It's summery.

To measure skin temperature using this device, first place the device 1 on the skin surface A, and first drive the pump 10 to send high temperature (for example, 40°C) gas from the thermostatic chamber 7 to the device 1. After applying high temperature load to skin side A for a while,
The pump 10 is stopped, and then the pump 14 is driven to send low-temperature (for example, 5° C.) gas from the constant temperature chamber 11 to the container 1 to apply a cooling load to the skin surface A for a while. drive is stopped and the cooling load is released. The purpose of warming the skin surface A with the high temperature gas sent from the constant temperature bath 7 is to initialize the temperature of the skin surface A before applying a cooling load from the low temperature constant temperature bath 11 to eliminate personal and environmental errors. This is to eliminate

FIG. 7 shows the skin temperature measured in this manner. In other words, when a high temperature load is applied, the skin temperature rises to about 40℃ after about 2 minutes, then when a cooling load is applied, it drops to about 5℃ after about 8 minutes, and then when the cooling load is removed, the skin temperature rises to about 20℃. Initial skin temperature (35 minutes later)
°C). In this way, the high temperature gas constant temperature bath 7
By separately providing a low-temperature gas constant temperature bath 11 and alternately applying a high-temperature load and a cooling load to the skin surface, more precise measurement diagnosis can be performed.

As is clear from the above embodiments, various design changes can be made to the skin temperature measuring device according to the present invention, and the method for measuring skin temperature using the skin temperature measuring device according to the present invention can also be modified as described above. This is not limited to the example shown, but the point is to send high or low temperature gas from a constant temperature gas generating part to the inside of the container to accurately measure the skin temperature in the high or low ambient temperature. All you have to do is measure it.

(Effects of the Invention) As explained above, according to the present invention, by bringing the container 1 into contact with the skin surface A of the body, it is not affected by external factors such as the environmental temperature and the surrounding air volume. The temperature characteristics of the skin temperature at a predetermined ambient temperature can be accurately measured without causing any physical pain to the person being measured, and the measurement results can be used as diagnostic data for the presence or absence of blood circulation disorder.
