Abstract
A flash steam generator to be used as an integral component of a steam sterilizer. The generator is constructed of a metal block having a first bore drilled lengthwise through the metal block. Surrounding the first bore are a plurality of additional heater bores in which heating elements are inserted. The generator is integral to the sterilizer piping and control systems. Water is supplied to the first bore by the sterilizer piping system, and electricity is supplied to the heating elements by the sterilizer power supply. The heating elements convert the electricity to heat, which transfers via the metal block to the first bore where the heat rapidly boils the water contained therein in what is essentially a flash vaporization process.
Claims12
A flash steam generator integral with a piping system and a electrical power supply of a medical device sterilizer comprising:
- a block of metal having a first bore extending through the entire block and in fluid connection with the piping system to provide steam to said sterilizer, and a plurality of heater bores in thermal connection with the first bore, each said heater bore having a first bore end and a second bore end;
- and
- a plurality of heating elements in electrical connection with the power supply and in thermal connection with the heater bores, one each being mounted at the first bore end of each heater bore and extending through each heater bore toward the second bore end of each heater bore.
A generator for providing a vaporized fluid substantially immediately to a device requiring pressurized vapor and being integral with a plurality of fluid conduits of said device, said generator comprising:
- a main body consisting essentially of a metal block having at least one fluid passage forming a vaporization chamber, said fluid passage extending from a first end to a second end of said metal block to form a fluid connection with said fluid conduits, and
- a heater element in said block being thermally adjacent but not in contact with said fluid passage,
- whereby said fluid passage is controllably filled with a fluid from one said fluid conduit, heat is controllably thermally transferred from said heater element to said fluid in said fluid passage and vaporizing said fluid, and said vaporized fluid is transferred under pressure from said fluid chamber through another said fluid conduit to said device.
A system for sterilizing objects using pressurized steam comprising:
- a sterilzier having a sterilization chamber, and having a piping system in fluid connection with an external water supply and in fluid connection with the sterilization chamber;
- and having an electrical power supply;
- and
- a flash steam generator integral with the piping system and electrical power suppy of the sterilizer comprising a block of metal having a first bore extending through the entire block and in fluid connection with the sterilizer piping system, and a plurality of heater bores in thermal connection with the first bore, each said heater bore having a first bore end and a second bore end;
- and a plurality of heating elements in electrical connection with the sterilizer power supply and in thermal connection with the heater bores, one each being mounted at the first bore end of each heater bore and extending through each heater bore toward the second bore end of each heater bore.
A flash steam generator integral with a piping system and an electrical power supply of a medical device sterilizer comprising:
- a block of metal having a first bore extending through the entire block and in fluid connection with the sterilizer piping system, and a plurality of heater bores in thermal connection with the first bore, each said heater bore having a first bore end and a second bore end;
- a plurality of heating elements in electrical connection with the sterilizer power supply and in thermal connection with the heater bores, one each being mounted at the first bore end of each heater bore and extending through each heater bore toward the second bore end of each heater bore wherein water flows into said first bore and steam is provided under pressure directly to a sterilizer jacket or chamber.
