An ingenious design is employed, so that structure is simpler, more compact, smaller and more flexible, comprehensive utilization rate of the parts is high, and manufacture cost and use cost can be better controlled.

A saturated steam generator which is provided with a heat source for heating water to generate saturated steam and which can be small-sized. A saturated steam generator for generating saturated steam by heating water with superheated steam resulting from being superheated in a heat transmission tube (16) inserted into a heat storage tank (10), characterized by the provision of a saturated steam generator tank (12), wherein in the heat storage tank (10), disposed in a heat storage section composed by having a solid heat storage material and a liquid heat storage material filled therein are a heat transmission tube (16) and a heater (44), which heats the solid heat storage material and the liquid heat storage material, it being arranged that superheated steam resulting from passing through the heat transmission tube (16) is used as a heat source to heat stored water (22) so as to generate saturated steam.

The invention relates to a steam sterilizer and a sterilization process, and in particular relates to a negative-pressure and low-temperature steam sterilizer and the sterilization process. The steam sterilizer comprises a sandwich layer and an internal chamber, wherein the internal chamber consists of a space enclosed by a front door, a back door and the sandwich layer; a steam channel is formed in the sandwich layer; the sandwich layer is connected with a sandwich layer steam inlet system through a pipeline; the internal chamber is connected with an internal chamber emptying system through a pipeline; the sandwich layer is communicated with the internal chamber through a pipeline, and a first pneumatic control valve is arranged on the pipeline; the internal chamber is connected with an internal chamber vacuumizing drainage system through a pipeline; and the sandwich layer is connected with a sandwich layer vacuumizing drainage system through a pipeline. The steam sterilization process comprises: (1) vacuumizing; (2) sandwich layer steam inlet; (3) heating; (4) sterilization. The low-temperature steam sterilization of a thermolabile article is realized; by virtue of the internal chamber vacuumizing drainage system, condensed water formed in the sterilization process can be effectively drained, and the steam quality and temperature uniformity of the internal chamber are ensured.

A sterilizer for sterilizing instruments and devices disposed therein. The sterilizer includes a vessel that has an inner wall and an outer wall. The inner wall defines a sterilization chamber. The outer wall is spaced from the inner wall to define a cavity surrounding the sterilization chamber. A heating element for vaporizing a fluid is disposed in a lower portion of the cavity. A fluid circuit is fluidly connected to the vessel to convey fluid to the cavity, to convey steam from the cavity to the sterilization chamber and to exhaust steam from the sterilization chamber. The fluid circuit includes a conduit that fluidly connects the sterilization chamber to the cavity. A valve is disposed in the conduit for controlling the flow of steam from the cavity to the sterilization chamber. A boiler pump is provided for conveying fluid to the cavity of the vessel.

Provided are a steam sterilizer, a single use / disposable container for use in the sterilizer, and a sterilization method. The container is a rigid or semi-rigid container having a sealable elongate conduit through which steam sterilant may be introduced into the container and steam sterilant and condensate may be removed from the container. Once one or more items to be sterilized are placed in the container a cover is sealed over the mouth of the container. The steam sterilizer has a sterilization chamber adapted to receive the container and provide sterilant within and around the container. Sterilant is provided to the container via the conduit which is sealed at the end of the sterilization process.

The invention relates to a double-layer steam sterilization pot and a moveable medical waste emergent disposal system. The sterilization pot comprises a pulse vacuum steam sterilizer pot body, a middle jacket layer and a heat preservation layer, wherein the middle jacket layer is arranged on the outer surface of the pulse vacuum steam sterilizer pot body, a middle jacket layer in a tightly connected manner; a middle interlayer is arranged on the outer surface of the pulse vacuum steam sterilizer pot body, a middle jacket layer and the inner surface of the middle jacket layer; the middle interlayer is capable of containing and introducing steam; the heat preservation layer is arranged on the outer surface of the middle jacket layer in a tightly connected manner; and the system comprises a feeding system, a discharge system, a high-temperature steam sterilization system, a steam generation system, a cooling system, a crushing packaging system, a waste gas treatment system, a wastewater pretreatment system and an auxiliary sterilization system. The system can be applied to emergent disposal on medical wastes involved in an epidemic situation and / or medical wastes of sudden disasters and / or daily medical wastes.

A sterilizer having a cassette for holding metal instruments or medical devices. The cassette includes a metallic container that defines a sterilization chamber. The container has at least one outer surface. A plurality of spaced-apart, elongated rails extend along the at least one outer surface of the container. Each of the rails includes a free, longitudinal edge wherein the edges of the rails lie in a first plane. An insulating shell encases the metallic container and the plurality of rails. An outer surface of the insulating shell lies in the first plane. A receiving unit includes a housing having an outer surface and an inner surface. The inner surface engages the edges of the rails and the outer surface of the insulating shell when the cassette is disposed within the inner housing. A plurality of spaced-apart elongated ribs extends along the outer surface of the housing.

The present invention provides a sterilizer having a housing defining a sterilization chamber. An opening in the housing communicates with the chamber. A surface surrounds the opening, and a door is movable between one of an open position allowing access to the chamber through the opening and a closed position covering the opening. A seal element is associated with the surface for forming a fluid-tight seal between the door and the surface when the door is in the closed position. An operating system is provided for applying pressure to one side of the seal from a first source external to the operating system to force the seal into engagement with the door. Sensing means are provided for monitoring the pressure applied to the seal from the first pressure source. A second source of pressure is provided in the operating system and is connectable to the seal. Valve means connect the pressure source to the steam system if the sensing means detects a pressure below a set pressure sufficient to sustain a seal between the door and the surface.
