Abstract
Some embodiments of this disclosure relates to systems and methods for imaging a patient'"'"'s vasculature. For example, near infrared (NIR) light can be used to illuminate a target area and light that is reflected or scattered from the target area can be used for generate an image of the target area. In some embodiments, the system can be configured such that the image shows the presence, absence, or extent of infiltration or extravasation in the target area. The system can be configured to document that presence, absence, or extend of infiltration or extravasation at an infusion site. In some embodiments, an imaging system can be mounted onto a patient so that the imaging system can monitor an infusion site, and the imaging system can be configured to automatically detect the presence of infiltration or extravasation.

195. A method of detecting infiltration or extravasation in tissue surrounding an infusion site on a patient, the method comprising:
-
illuminating the tissue surrounding the infusion site with near infrared (NIR) light of a first wavelength during a first time; receiving light of the first wavelength reflected or scattered from the tissue onto one or more light sensors; illuminating the infusion site with near infrared (NIR) light of a second wavelength during a second time; receiving light of the second wavelength reflected or scattered from the tissue onto the one or more light sensors; generating one or more images of the tissue using the light of the first wavelength received by the one or more light sensor and using the light of the second wavelength received by the one or more light sensors; displaying the one or more images of the tissue to a medical practitioner; and detecting the presence of infiltration or extravasation in the tissue based at least in part on the one or more images of the tissue. - View Dependent Claims (196, 197, 198, 199, 200, 201, 202, 203, 204)

205. A system for facilitating the detection of infiltration or extravasation in a target area at an infusion site on a patient, the system comprising:
-
one or more light sources configured to pulse on and off; one or more light sensors configured to receive light from the one or more light sources that is reflected or scattered by the target area; a controller configured to generate one or more images of the target area from the light received by the one or more light sensors; a display configured to display the one or more images of the target area; wherein the system is configured such that the displayed one or more images indicate the presence of infiltration or extravasation when infiltration or extravasation is present in the target area. - View Dependent Claims (206, 207, 208, 209, 210, 211, 212, 213)

214. A system for facilitating the detection of infiltration or extravasation in a target area at an infusion site on a patient, the system comprising:
-
a light source configured to direct light onto the target area; a light sensor configured to receive light from the target area; a controller configured to generate an image of the target area from the light received by the light sensor; a display configured to display the image of the target area; wherein the system is configured such that the displayed image indicates the presence of infiltration or extravasation when infiltration or extravasation is present in the target area. - View Dependent Claims (215, 216, 217, 218)
