Abstract

A medical instrument thermal treatment system according to the present invention is in the form of a stand including a thermally treated tray to thermally treat medical instruments. The stand includes a frame to support the tray, while a drape including a sensing device is disposed over the tray to form a drape container or receptacle within the tray for collecting a sterile medium. The tray is thermally treated to heat the sterile medium in order to warm medical instruments or other medical items placed in the tray. The sensing device provides a signal to the system indicating the presence of liquid and/or leaks within the drape container to facilitate control of system operation.
