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 and including;
a light source to irradiate light to said sensor chip, anda light receiving element for receive light output from internal of said sensor chip;
a fixed engaging member fixed to the measuring apparatus main body housing; and
a movable engaging member disposed in the measuring apparatus main body housing to be movable,wherein the biological component sensor is held by the fixed engaging member and the movable engaging member, andthe biological component sensor is configured 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 by an amount of light detected by the light receiving element.

Abstract
A measuring apparatus uses 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. The biological component sensor is disposed in a measuring apparatus main body housing. A fixed engaging member and movable engaging member disposed on a sensor chip support table fixed to the measuring apparatus main body housing fix and support the sensor chip holding frame, and the sensor chip can be thus replaced. The biological component sensor contacts a forearm portion of a human body, and a biological component exuded from a contact part of the forearm portion is caused to contact the sensor chip to change a physical or chemical surface property of the sensor chip, thereby measuring the change through an irradiation of an inspection light to calculate concentration of the biological component.

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 engaging member fixed to the measuring apparatus main body housing, a movable engaging member disposed in the measuring apparatus main body housing to be movable, the biological component sensor being held by the fixed engaging member and the movable 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.

10. 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 engaging member fixed to the measuring apparatus main body housing, a movable engaging member disposed in the measuring apparatus main body housing to be movable, the biological component sensor being held by the fixed engaging member and the movable 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, thereby measuring a biological component exuded from the forearm portion of the human body;
whereinthe biological component sensor is attached to the measuring apparatus main body housing and then the inspection light is irradiated, thereby deciding a type of the sensor chip or an attachment situation of the biological component sensor based on a magnitude of a signal obtained by measuring the inspection light reflected from the biological component sensor.
