  • Patent number: 5158363
    Abstract: A steam sterilization indicator for indicating both exposure to steam and sterilization is provided. The steam sterilization indicator includes a backing member. A tablet formed of a compound having a first melting point and second melting point which is lower that the first melting point, the second melting point being the melting point of the compound exposed to steam is also provided. A wick is affixed to the backing member adjacent to the tablet. A steam permeable material covers the tablet and the wick. Upon melting, the tablet material is absorbed by the wick. A handle is affixed to the backing member. One end of the handle includes a steam exposure indicator formed of a color changing ink which changes color in the presence of steam.

  • Patent number: 4073314
    Abstract: A disposable valve, including a body having a plurality of ports and a core which is telescoped in the body and is rotated therein to provide connections between various ports, is provided with an improved arrangement for rotatably securing the core in the body and for halting its rotation at predetermined positions. The core is provided at one end with a splined bore, and is rotatably secured within the body by means of a fastener having a threaded shaft portion designed to be press-fitted into the splined bore. The body includes a boss which protrudes from it at one end, and the core includes a protruding member positioned to engage the corners of the boss so that the rotation of the core is halted. Both the boss and protruding member are encircled by a skirt formed on either the body or core to protect them from physical damage.
