PROBLEM TO BE SOLVED: To provide a clinical thermometer sterilizer capable of easily sterilizing thermometers.SOLUTION: A clinical thermometer sterilizer 10 includes: a housing 12 where insertion ports 20 to which tip parts 54 of clinical thermometers 50 are inserted are provided; a light source 30 which is provided inside the housing 12 and irradiates the tip parts 54 of the clinical thermometers 50 inserted into the insertion ports 20 with ultraviolet light; and a control part 40 which controls lighting of the light source 30. The clinical thermometer sterilizer 10 may further include sensors 24 for detecting insertion of the clinical thermometers 50 into the insertion ports 20. The control part 40 may light up the light source 30 when insertion of the clinical thermometer 50 is detected by the sensor 24.SELECTED DRAWING: Figure 1【課題】簡便に体温計を殺菌できる体温計殺菌装置を提供する。【解決手段】体温計殺菌装置10は、体温計50の先端部54が挿入される挿入口20が設けられる筐体12と、筐体12の内部に設けられ、挿入口20に挿入される体温計50の先端部54に紫外光を照射する光源30と、光源30の点灯を制御する制御部40と、を備える。体温計殺菌装置10は、挿入口20への体温計50の挿入を検知するセンサ24をさらに備えてもよい。制御部40は、センサ24により体温計50の挿入が検知された場合に光源30を点灯させてもよい。【選択図】図1
