Abstract: Systems and methods for measuring a temperature at a location within a patient's body such as at an in vivo location proximate to a site of intravenous fluid administration, are disclosed. In some embodiments, an insertable device includes an insertion tube member having a tip configured to be inserted into a blood vessel (or other body lumen) of a patient, and a temperature sensor operatively coupled to the insertion tube proximate the tip and configured to measure a temperature within the blood vessel during administration of a fluid through the insertion tube. The device may also include a controller operable to receive one or more signals from the temperature sensor indicative of the temperature within the blood vessel proximate the tip of the insertion tube.

Abstract: An improved wound dressing is provided which comprises a backing layer bearing a reference marking, a hydrocolloid layer and a release layer. The hydrocolloid swells in use. This swelling can be seen or felt through the backing layer. When the swelling extends to or beyond the reference marking, the dressing should be changed to prevent leaking. Thus, the dressing can be left in place for as long as possible, but not so long as to damage the underlying skin.
