Biological information measurement device and pulse oximeter
First Claim
1. A biological information measurement device comprising:
- a body part; and
a wearable part that is directly and detachably attached to the body part and is to be worn on a finger of a living body, the wearable part and the body part being in physical contact with each other,wherein the biological information measurement device includes a light source unit and a light receiving unit that are arranged so as to oppose each other with said finger therebetween when said wearable part is worn on said finger,wherein said body part includes an electric circuit, a power supply unit, and a first terminal unit, the electric circuit including a signal processing unit, the first terminal unit being electrically connected to the electric circuit,wherein said wearable part includes at least one of said light source unit and said light receiving unit, and a second terminal unit that is electrically connected to the at least one of said light source unit and said light receiving unit,wherein said first terminal unit and said second terminal unit are mechanically in contact with and electrically connected to each other,wherein said signal processing unit acquires a digital value concerning a pulse wave based on a signal output from said light receiving unit, the signal being output by said light receiving unit receiving light that is emitted from said light source unit and passes through said finger, andwherein said wearable part is selectable in response to a size of said finger among a plurality of wearable parts having different dimensions.

Abstract
A device includes a body part and a wearable part integrally attached to the body part and to be worn on a finger, and includes a light source unit and a light receiving unit that are arranged so as to oppose each other. The body part includes an electric circuit including a signal processor, a power supply unit, and a first terminal unit electrically connected to the electric circuit, and the wearable part includes at least one of the light source unit and the light receiving unit, and a second terminal unit electrically connected to the at least one of them. The first and second terminal units are mechanically in contact with and electrically connected to each other. The signal processor acquires a digital value concerning a pulse wave based on a signal output from the light receiving unit receiving light from the light source unit via the finger.
