Abstract: A device that indicates an internal pressure of an inflatable medical cuff. The device includes a membrane movable in response to a difference between an internal pressure of the device and an external pressure. The device includes a movable internal pressure indicator. The movable internal pressure indicator is operably associated with at least a portion of the membrane.

Abstract: An indicating device for indicating the number of times in which a surgical fitting has been autoclaved, the device including a body which includes first and second sets of teeth and a bimetallic indexing ring having teeth thereon, the arrangement being such that on thermal expansion and contraction of the indexing ring, its teeth engage those of the body so as to rotate the ring in a step wise manner relative to the body so as to thereby indicate the number of heat cycles to which the indicating device has been subjected, the indexing ring being the only movable part of the device.
