発明の名称 (英語) MEDICAL PRODUCT THAT EMITS NEAR-INFRARED FLUORESCENCE AND MEDICAL-PRODUCT USAGE-STATUS ASCERTAINMENT DEVICE
発明の概要(英語)

[Problem] To make it possible to reliably ascertain the usage status of a medical product, e.g. the damage status of said medical product or the presence or absence of said medical product. [Solution] A medical product (80) is provided with a light-emission-capable septum (83) (constituent member), the surface of which contains a light-emitting agent that emits near-infrared fluorescence upon being illuminated with excitation light. Even if part of the septum detaches due to damage, forming a core (83a) (detached fragment), the surface of said core also contains the light-emitting agent. This medical-product usage-status ascertainment device (10) has the following: the aforementioned medical product that emits near-infrared fluorescence

an illumination unit (130) that shines, toward said medical product, excitation light that excites the light-emitting agent

an optical filter (140) that blocks the excitation light but transmits the near-infrared fluorescence emitted by the light-emitting agent

a camera (150) (imaging unit) that receives near-infrared fluorescence that has passed through the optical filter

and a monitor (160) (display unit) that displays images taken by the camera. The monitor displays an image based on near-infrared fluorescence from the septum, and if the septum has been damaged, displays an image based on near-infrared fluorescence from the core.
