PORTABLE PHOTODYNAMIC DISINFECTION LIGHT DELIVERY DEVICE FOR CATHETER DISINFECTION

摘要

The present invention provides a portable photodynamic disinfection light delivery device (100) comprising: two opposing light sources (26, 28), an energy source (34) to supply energy to the light sources (26, 28), and a housing (8) for receiving the two light sources (26, 28) and the energy source (34); wherein (i) the housing 8 includes two members (10, 12) each having a clamp portion (14, 16) for receiving one of the two light sources (26, 28) and an attachment mean (18) connecting the clamp portions (14, 16); (ii) the clamp portions (14, 16) during photodynamic disinfection surround a catheter disinfection site (20); and (iii) the two light sources (26, 28) together provide circumferential illumination at least one wavelength that can activate at least one photosensitizer so as to reduce microbes located at the catheter disinfection site (20). The present invention provides a catheter disinfection method comprising: applying circumferential illumination at a wavelength that activates a photosensitizer located at a catheter disinfection site (20) so as to reduce microbes located at the catheter disinfection site (20) using the portable photodynamic disinfection light device (100) described above.
