Medical product emitting near-infrared fluorescence and medical product usage status checking apparatus

Abstract

[Problem] To accurately check a usage status of a medical product such as a damage status of the medical product or existence or nonexistence of the medical product.[Solution] A medical product (80) is configured to include a light-emissive septum (83) (constituent member) which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof. Even in a case where a portion of the septum is separated as a core (83a) (separate piece) due to damage, the luminescent agent is also included on a surface of the core. A medical product usage status checking apparatus (10) is configured to include a medical product which emits the near-infrared fluorescence, an irradiation unit (130) which irradiates the medical product with excitation light which excites the luminescent agent, an optical filter (140) which blocks the excitation light and transmits the near-infrared fluorescence emitted by the luminescent agent, a camera (15) (imaging unit) which receives the near-infrared fluorescence passing through the optical filter, and a monitor (160) (display unit) which displays an image captured by the camera. An image based on the near-infrared fluorescence of the septum is displayed on the monitor and in a case where damage occurs in the septum, an image based on the near-infrared fluorescence of the core is displayed on the monitor.

         8 . A light-emissive medical product which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof, wherein the medical product emitting near-infrared fluorescence is at least one selected from the group consisting of a light-emissive suture thread which is formed with a synthetic thread where the luminescent agent is kneaded in a resin material, a light-emissive cloth-formed consumable item into which the synthetic thread is woven, a light-emissive nonwoven cloth-formed consumable item which includes the synthetic thread without weaving, a scissor, a pincette, a catheter, an injection needle, and a tube formed with a material with which the luminescent material is kneaded. 
     
     
         9 . A medical product usage status checking apparatus comprising:
 a light-emissive medical product which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof;   an irradiation unit which includes a light source emitting excitation light which excites the luminescent agent and irradiates an operative field where existence or nonexistence of the medical product is to be checked with the excitation light emitted from the light source;   an optical filter which blocks the excitation light and transmits the near-infrared fluorescence emitted by the luminescent agent;   an imaging unit which receives the near-infrared fluorescence passing through the optical filter; and   a display unit which displays an image captured by the imaging unit,   wherein, in a case where the medical product exists in the operative field, an image based on the near-infrared fluorescence of the medical product is displayed on the display unit,   wherein the medical product is at least one selected from the group consisting of a light emissive suture thread which is formed of a synthetic thread where the luminescent agent is kneaded in a resin material, a light-emissive cloth-formed consumable into which the synthetic thread is woven, a light emissive non-woven cloth-formed consumable item which includes the synthetic thread without weaving, a scissor, a pincette, a catheter, an injection needle, and a tube which is formed with a material in which the luminescent agent is kneaded.   
     
     
         10 . The medical product usage status checking apparatus according to  claim 9 , further comprising a control unit which informs that the medical product exists in the operative field in a case where the image based on the near-infrared fluorescence is detected.
