Abstract
Abstract A sheath package for use with a clinical temperature measurement probe. An elongate sheath has a mouth at one end for receiving the probe and is normally enclosed by a cover, the sheath extending into a mouth at one end of the cover such that the probe may be inserted in the sheath while the latter is in the cover and then withdrawn with the sheath thereon. A signal means has a normally concealed position when the sheath is in the cover before being withdrawn and is moved to a position in which it is visible when the probe with the sheath thereon is reinserted in the cover.
