Abstract
There is provided a method of supplying a fluid to a placement site. For instance, a sensor set is first mounted onto a skin of a user, and a placement site is contacted with the sensor set. The sensor set includes a base to secure the sensor set to the skin of the user; a cannula coupled to and extending from the base; an insertion device operatively coupled to the sensor set and the cannula to facilitate insertion of the cannula to contact the placement site; an externally extending conduit; and a sensor. The cannula has at least one lumen with an end for fluid communication with the placement site, and also has at least one port formed near another end of the lumen opposite the end for fluid communication. The conduit is in fluid communication with the at least one port of the cannula. The sensor has a sensor portion exposed by the at least one port in the at least one lumen of the cannula to determine a body characteristic of the user at the placement site. After the sensor set is mounted on the user's skin, a fluid is introduced through the externally extending conduit and the lumen to the placement site. Kits for carrying out the inventive methods are also provided.
