BIOLOGICAL COMPONENT MEASURING APPARATUS AND METHOD
First Claim
1. A biological component measuring apparatus comprising:
- a biological component sensor including a plate-shaped sensor chip having a biological component sensing function and a sensor chip holding frame surrounding and holding the sensor chip;
a measuring apparatus main body housing for mounting the biological component sensor thereon;
a fixed click-shaped engaging member fixed to the measuring apparatus main body housing; and
a movable click-shaped engaging member disposed in the measuring apparatus main body housing to be movable,wherein the biological component sensor is held by the fixed click-shaped engaging member and the movable click-shaped engaging member, andthe biological component sensor is caused to come in contact with a forearm portion of a human body and a concentration of a biological component exuded from a contact portion of the forearm portion is measured.

Abstract
It is an object to provide a measuring apparatus and method which can easily measure an amount of a biological component such as glucose without requiring an ordinary person who is to be measured to have special knowledge and techniques. A measuring apparatus according to an embodiment of the present invention uses a biological component sensor including a plate-shaped sensor chip 112 having a biological component sensing function and a sensor chip holding frame 111 for surrounding and holding the sensor chip 112, and the biological component sensor is disposed in a measuring apparatus main body housing 110. A fixed click-shaped engaging member 118 and a movable click-shaped engaging member 119 are disposed on a sensor chip support table 124 fixed to the measuring apparatus main body housing 110, and they fix and support the sensor chip holding frame 111 and the sensor chip can be thus replaced. The biological component sensor of the measuring apparatus is caused to come in contact with a forearm portion 100 of a human body and a biological component exuded from a contact part of the forearm portion is caused to come in contact with the sensor chip to change the physical or chemical surface property of the sensor chip, thereby measuring the change through an irradiation of an inspection light. Thus, a concentration of the biological component is calculated.

9. A biological component measuring method comprising:
-
bringing a biological component measuring apparatus including at least a biological component sensor including a plate-shaped sensor chip having a biological component sensing function and a sensor chip holding frame surrounding and holding the sensor chip, a measuring apparatus main body housing for mounting the biological component sensor thereon, a fixed click-shaped engaging member fixed to the measuring apparatus main body housing, a movable click-shaped engaging member disposed in the measuring apparatus main body housing to be movable, the biological component sensor being held by the fixed click-shaped engaging member and the movable click-shaped engaging member, a light source disposed in the measuring apparatus main body housing and serving to irradiate an inspection light on the biological component sensor, and a photoreceptor which receives the inspection light emitted from the light source and reflected from the biological component sensor, in a close contact with a forearm portion of a human body; irradiating the inspection light from the light source; receiving the inspection light reflected from the biological component sensor through the photoreceptor; and measuring an amount of a biological component from an amount of the light.
