  • Patent number: 8252246
    Abstract: A portable steam sterilizer for surgical and dental instruments includes an outer casing and a pressure chamber configured to receive steam therein. A tray is configured to hold the instruments and is releasably received within the pressure chamber while a boiler is in fluid communication with the pressure chamber for providing steam thereto. The sterilizer further includes a container for receiving condensed steam evacuated from the pressure chamber. The container is spaced from the outer casing and includes a main body and a lid that is substantially non-rotationally coupled to the main body. A conduit is coupled to the lid and fluid communicates the container with the pressure chamber. The main body of the container may include a base while the lid may include a wall oriented generally orthogonal to the base.

  • Patent number: 8236253
    Abstract: A portable steam sterilizer for surgical instruments includes a tray configured to hold the instruments and a pressure chamber. The pressure chamber includes a cavity portion and a handle portion. The cavity portion includes a set of walls and is configured to releasably receive the tray, while the handle portion is coupled to the tray for selectively inserting and removing the tray respectively into and from within the cavity portion. The handle portion is sealingly engageable with the cavity portion to thereby define the pressure chamber. A steam inlet fluidly communicates the pressure chamber with a source of steam to selectively permit steam to flow from the source of steam and into the pressure chamber. A steam outlet fluidly communicates the pressure chamber with a steam management assembly to selectively permit steam to flow from the pressure chamber and into the steam management assembly.

  • Patent number: 7951342
    Abstract: A sterilizer (20) is provided having a steam filled sterilizer chamber (24) for sterilizer articles placed within the chamber (24). An electronic air valve (186) is provided to control the venting rate of the steam is vented back to a water reservoir (140) after the articles have been sterilized. The electronic air valve (186) also vents the chamber (24) in a controlled manner during the heat up portion of the sterilization cycle to obtain an optimum saturated steam environment with the chamber (24) for the sterilizing process. The sterilizer (20) has pre-programmed and programmable sterilization cycles. And the drying times of each of these cycles is programmable by a user. The programmable sterilization cycles also provide a programmable vent rate which may be selected by the user to minimize damage to the sterilized articles. A steam condensing coil (200) is associated with the water reservoir (140) to minimize pressure build up within the water reservoir (140).

  • Patent number: 7376991
    Abstract: A medical examination table has a seat section and a back section supported on a base. The seat and back sections are selectively adjustable to place a patient resting thereon in various positions for examination or the performance of medical procedures. The seat section has a relatively low profile that accommodates storing various accessories beneath the seat section while providing a high level of patient comfort and ensuring a low overall table height. In one embodiment, the seat section comprises a seat frame having a central open area, and a layer of web material extending over the open area.
