The imaging device 28 with the flesh color measuring device configured as described above includes a color imaging device 80, a pointer device 82 for outputting a relatively thin light beam into the imaging range of the color imaging device, and a flesh color measuring device. Since the device 84 is integrally provided, the patient-side worker can indicate a portion to be measured by the skin color measuring device 84 by using the light beam, and at the same time, the medical worker 50 can use the color imaging device 80. The color beam to be measured can be accurately known from the light beam imaged by the method. Therefore, the part to be measured by the skin color measuring device 84 can be accurately positioned at the part designated by the medical staff. Further, after the colorimetric scheduled portion is positioned, the skin color of the skin of the patient 18 can be measured without holding the device.

The first colorimetric value C ₁ is calculated based on the spectrum obtained by the above, and the second colorimetric value C ₂ is calculated based on the spectrum obtained by the light receiving device 104 in a state where the part is ischemic, The colorimetric value difference DC is calculated by subtracting the _second colorimetric value C2 from the _first colorimetric value C1. The colorimetric value difference DC represents a skin color in which blood closely related to a change in skin color has been removed, that is, a skin color in which the influence of a color unique to a living body related to the amount of melanin has been removed. Therefore, since the skin color is obtained as an objective value, the skin color of the living body can be easily determined without requiring skill.

According to the present embodiment, the skin color measuring device 8
Since the center of the pressing member 92 bonded to the tip of the fourth member is formed by the light transmitting wall 98, the pressing member 92 is compared with a case where only the living skin around the irradiation site is pressed by the pressing member 92. Since the pressed portion is pressed evenly and the ischemic operation is sufficiently performed, the skin color can be measured more accurately.

Further, according to the present embodiment, the first pressing force display device 94 indicates the pressure range in which extraneous light is not mixed and the pressing portion of the skin of the patient 18 is not ischemic. Starts the skin color measurement device 84 with an appropriate pressing force.
8, the skin color can be accurately measured.

Further, according to the present embodiment, the body temperature sensor 100 is provided so that the housing 90 is inserted so that the distal end thereof is located at substantially the same position as the surface of the pressing member 92 pressed against the skin. Therefore, when the pressing member 92 is pressed against the skin of the patient 18, the body temperature sensor 100 is also pressed against the epidermis, so that the colorimetric value of the skin of the patient 18 is measured and at the same time, the body temperature of the pressed portion of the skin of the patient 18 is also measured. Measurements can be made at the same time, and the relationship between skin color and body temperature at the colorimetric site can be known.

While one embodiment of the present invention has been described with reference to the drawings, the present invention can be applied to other embodiments.

For example, in the above-described embodiment, the skin color measuring device 84 also has a function as an ischemic device, but the function as an ischemic device is not necessarily required. When the function as an ischemic device is not required, the intermediate member 88, the secondary spring 108, and the second pressing force display device 96 become unnecessary.

In the above-described embodiment, the imaging device 28 with the flesh color measuring device is operated by the patient side operator.
It may be operated directly by the patient.

In the above-described embodiment, the first pressing force display device 94 is composed of the guide hole 112, the guide protrusion 110, and the optimum pressing force display portion 114. May be displayed, and a part of the intermediate member 88 may be made of a transparent material. In this case, the intermediate member 88 of the housing 90
, Ie, the contraction of the first spring 106 is displayed, whereby the pressing force is displayed.

In the above-described embodiment, the first pressing force display device 94 and the second pressing force display device 96 are constituted by a pair of guide holes and guide projections.
Alternatively, another method such as calculating the pressing force from the moving distance of the intermediate member 88 and displaying the pressing force on the color image display device 26 may be used. When the pressing force is displayed on the color image display device 26, the problem that it is difficult to confirm the pressing force when the patient himself presses the skin color measuring device 84 against the patient's face is solved.

In the above-described embodiment, the pressing member 92 is attached to the surface of the contact member 91 which is pressed against the skin of the patient 18, but the housing 90 may be directly pressed. Absent.

In the above-described embodiment, the contact member 91 to which the pressing member 92 is attached is detachably attached by being screwed into the housing 86.
Only the pressing member 92 may be replaceable by joining the contact member 91 and the pressing member 92 with a flat fastener or the like.

In the above-described embodiment, the color imaging device 80, the pointer device 82, and the skin color measurement device 84 are arranged in the imaging device 28 with the flesh color measuring device such that the centers thereof are aligned. However, they are not necessarily arranged on a straight line, and may be arranged, for example, so as to form a triangle with their centers. In this case, there is an advantage that the imaging device with the flesh color measuring device can be downsized.

In the above-described embodiment, the skin color measuring device 8
4 was provided with one body temperature sensor 100,
A plurality of body temperature sensors 100 may be provided, and the average thereof may be calculated as the body temperature of the skin at the pressed part.
