Plug for high-pressure processing machines with a bag, comprising a duct for the passage of a pressure-transmitting fluid to the bag, another duct for filling and emptying of a product to be pressurized and a valve. The plug is further provided with a rod for opening and closing the valve. Said rod is located in the duct for the product and has its own inner duct joined to a cleaning agent chamber for the passage of the cleaning agent through the product duct. The invention also relates to a machine incorporating said plug and a method for the processing of pumpable substances. Hygienic design and very high pressure sealing requirements are met by the invention.

An apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12 C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector.

To perform sterilization using a sterilization member that has a treatment surface that is a surface on which a plurality of protrusions each having a leading end that is thinner than a diameter of a microorganism that is to be killed are provided, a sterilization member on which each protrusion has a height that is greater than or equal to half the diameter of the microorganism that is to be killed is used as the sterilization member, and a fluid that contains the microorganism that is to be killed is caused to strike the treatment surface to kill the microorganism that is to be killed.

A method for sterilizing a concentrated composition and a diluent. The diluent is contained in a large container, and the concentrated composition is contained in a small container that is positioned within the large container. The combined containers are placed in at least one sealing layer that is hermetically sealed, and is also preferably placed in a second sealing layer that is also hermetically sealed. The bagged container is then placed in a carton, which preferably has a liner, and the carton is closed. The carton is then irradiation sterilized. The carton is delivered to the clean room. At a first staging area, the carton is opened and the bagged container is removed and brought to a second staging area. At the second staging area, the second sealing layer is removed and the container can be stored in the first sealing layer. The container is brought into the clean environment, where the first sealing layer is removed. At that point, the small container is opened and the chemical composition is released into the large container, so that the chemical composition mixes with the diluent. The container can then be shaken until the chemical composition is thoroughly mixed with the diluent.

The invention relates to a multi-stage medical sewage sterilization device and method based on graphene nano technologies. The multi-stage sterilization device comprises multiple stages of graphene nano composite sterilization grids, a graphene photocatalytic sterilization tank, a graphene-modified diatom ceramic disinfection tank, an ultrasonic sterilization tank and a laser and near-infrared sterilization device. Compared with a traditional method, the present invention has a more thorough killing or blocking effects on pathogenic bacteria, parasite eggs and the like in various medical sewages. In addition, the device of the present invention can be disassembled and cleaned regularly, and has a long service life, thus the process cost is reduced.

A cleaning system for a set of instruments associated or in contact with an image plate readout device, as well as to a readout device that includes the cleaning system. The cleaning system includes a disinfecting element, which emits electromagnetic radiation and/or ultrasonic radiation capable of destroying disease carriers, and which is adapted to emit said radiation towards an image plate conveyor mechanism encompassed by the image plate readout device.

A sterilization system having a controllable non-ironing microwave radiation source for providing microwave energy for combining with a gas to produce atmospheric low temperature plasma for sterilizing biological tissue surfaces or the like. A plasma generating region may be contained in a hand held plasma applicator. The system may include an impedance adjustor e.g. integrated in the plasma applicator arranged to set a plasma strike condition and plasma sustain condition. The gas and microwave energy may be transported to a plasma generating region along an integrated cable assembly. The integrated cable assembly may provide a two way gas flow arrangement to permit residual gas to be removed from the surface. Invasive surface plasma treatment is therefore possible. The plasma applicator may have multiple plasma emitters to produce a line or blanket of plasma.
