Abstract
A pulse photometry probe includes a holding member that includes a contact face which is to be in contact with living tissue of a patient, an emitter that is placed in the holding member, a detector that is placed in the holding member and detects light emitted from the emitter, and, a spacer that is disposed between the contact face and the emitter and has an opening, wherein an air layer defined by the opening is disposed between an emitting face of the emitter and the contact face.
Claims12
A pulse photometry probe comprising:
- a holding member that includes a contact face which is to be in contact with living tissue of a patient and a lower sheet in which a through hole is formed;
- an emitter that is placed in the holding member;
- a detector that is placed in the holding member and detects light emitted from the emitter;
- a spacer that is disposed between the contact face and the emitter and has an opening;
- a transparent member that is disposed between the contact face and the emitter, covers the opening of the spacer, and is harder than the holding member;
- and
- a heat radiation layer that is disposed between the spacer and the lower sheet and has a thermal conductivity that is higher than a thermal conductivity of the spacer,
- wherein an air layer defined by the opening is disposed between an emitting face of the emitter and the contact face, and
- wherein the transparent member, emitter, detector, and opening of the spacer are aligned along a linear direction.

A pulse photometry probe comprising:
- a holding member that includes a contact face which is to be in contact with a finger of a patient and a lower sheet in which a through hole is formed;
- an emitter that is placed in the holding member;
- a detector that is placed in the holding member and detects light emitted from the emitter;
- a spacer that is disposed between the contact face and the emitter and has an opening;
- a transparent member that is disposed between the contact face and the emitter, covers the opening of the spacer, and is harder than the holding member;
- and
- a heat radiation layer that is disposed between the spacer and the lower sheet and has a thermal conductivity that is higher than a thermal conductivity of the spacer,
- wherein an air layer defined by the opening is disposed between an emitting face of the emitter and the contact face, and
- wherein the air layer disperses most of the heat from the emitter to the spacer thereby preventing low temperature burns in the finger.
