|1. (WO2018012280) OPTICAL OUTPUT MONITORING DEVICE, OPTICAL OUTPUT MONITORING METHOD, PROTECTIVE CAP, AND ADAPTER|
|Applicants:||HAMAMATSU PHOTONICS K.K.
|Title:||OPTICAL OUTPUT MONITORING DEVICE, OPTICAL OUTPUT MONITORING METHOD, PROTECTIVE CAP, AND ADAPTER|
This optical output monitoring device is provided with a light receiver 11, an attachment unit 12, an adapter 20 and a protective cap 30, and monitors the power of light output from a light emitting end 40a of a catheter 40 incorporating an optical fiber 41. The protective cap 30 has an insertion opening into and from which a part of the catheter 40, in a certain range on the light emitting end side thereof, can be freely inserted and removed, and a window portion 32 which transmits light output from the light emitting end of the catheter 40. The protective cap 30 is fixed in position by inserting the same into a through-hole in the adapter 20. The adapter 20 is fixed in position by being attached to the attachment unit 12. It is thus possible to achieve an optical output monitoring device with which optical output monitoring can be performed easily while maintaining the cleanliness of the catheter.
