Compositions, devices and processes related to etching of a very thin layer or fine particles of a metal are disclosed for monitoring a variety of parameters, such as time, temperature, time-temperature, thawing, freezing, microwave, humidity, ionizing radiation, sterilization and chemicals. These devices have capabilities of producing a long and sharp induction period of an irreversible visual change. The devices are composed of an indicator comprising a very thin layer of a metal and an activator, e.g., a reactant, such as water, water vapor, an acid, a base, oxidizing agent or their precursors, which is capable of reacting with the said indicator. Ink formulations composed of a metal powder and a proper activator can be used for monitoring several sterilization processes, such as sterilization with steam. When water is used as an activator, a thin layer of metals, such as that of aluminum can be used as steam sterilization or humidity indicator.

A sterilization system includes a communication hub that is configured to transfer information between devices of the system such as a sterilizing cabinet, biological indicator analyzer, and a server in order to allow a user to track a medical device throughout a sterilization process. The server may provide data to the sterilizing cabinet during a sterilization process that may be used to verify that the medical device is compatible with the sterilizing cabinet, and to automatically select a compatible sterilization cycle to perform on the medical device. Automatic selection of sterilization cycles and confirmation of compatibility reduces the possibility for user error, which could result in contaminated medical devices being placed back into service. Automatic selection of sterilization cycles also allows users to more efficiently configure and perform sterilization cycles while being confident that the medical device will be sterile upon completion.

The present disclosure relates to a bone graft composition containing hydroxypropyl methylcellulose and a preparation method therefor. More specifically, a bone graft composition containing hydroxypropyl methylcellulose in an amount that provides optimum osmotic properties and shape retainability, and a preparation method therefor.

The present disclosure provides a sterilization exhaust gas treatment system, which may include a gas liquefaction recovery system, a pressure swing adsorption recovery system, a reaction system, a temperature swing adsorption recovery system, a hydration system, a recovery and storage system, and a wastewater treatment system. The gas liquefaction recovery system, the pressure swing adsorption recovery system, the reaction system, the temperature swing adsorption recovery system, and the hydration system may be fluidly connected in sequence through first connecting pipes. The gas liquefaction recovery system, the pressure swing adsorption recovery system, and the temperature swing adsorption recovery system may each be fluidly connected to the recovery and storage system through second connecting pipes. The hydration system may be fluidly connected to the wastewater treatment system through wastewater pipes. The present disclosure also provides a method for treating ethylene oxide-containing sterilization exhaust gas using the sterilization exhaust gas treatment system.

An ethylene oxide adsorption recovery system includes a tower body defining a gas channel extending longitudinally therein. A sidewall of the tower body further comprises a plurality of mounting holes disposed longitudinally along the side wall and in communication with the gas channel. A bottom portion of the tower body includes a first pipe in communication with the gas channel, and a top portion of the tower body includes a second pipe in communication with the gas channel. A plurality of adsorption panels is coupled to the tower body through corresponding respective mounting holes of the plurality of mounting holes, each of the plurality of adsorption panels extends into the gas channel. A sealing door is movably coupled to the sidewall of the tower body and configured to selectively fix each of the plurality of adsorption panels to a respective mounting hole of the plurality of mounting hole.

The present disclosure discloses systems and methods for treating ethylene oxide waste gas. The system for treating ethylene oxide waste gas includes a compounding treatment assembly, an adsorption treatment assembly, and a hydration treatment assembly. The compounding treatment assembly includes a compounding tower to contain a compounding substrate, a first gas inlet, and a first gas outlet. The adsorption treatment assembly includes an adsorber to contain an adsorbent, a second gas inlet, and a second gas outlet. A first connecting pipe connects the first gas outlet with the second gas inlet. The hydration treatment assembly includes a hydration tower to contain water, a third gas inlet, and a third gas outlet. A second connecting pipe connects the second gas outlet with the third gas inlet and an exhaust pipe in communication with the third gas outlet exhausts the gas from the hydration tower.

The present disclosure provides a gas liquefaction separator, a gas liquefaction recovery system, and a method for separating and recovering ethylene oxide. The gas liquefaction separator includes a housing, a blocking plate, a gas baffle, and a liquid collector, the latter three being located inside the housing. The liquid collector—an outer edge of which is connected to an inner wall of the housing—is located below the gas baffle, which is located below the blocking plate. The liquid collector includes a first flow guide surface, on a bottom portion of which is disposed a first hole. The gas baffle—an upper surface of which forms a second flow guide surface and an outer edge of which has a protrusion(s)—is connected to the first flow guide surface through the protrusion(s), thereby forming a second hole between the outer edge of the gas baffle and the first flow guide surface.

A sterilization method is provided for sterilizing a surgical instrument having an antimicrobial coating formed from applying a solution including a silane quaternary ammonium ion or salt thereof, the method comprising sterilizing the surgical instrument using a low temperature sterilization technique. The low temperature sterilization technique may include low temperature autoclave, exposure to ultraviolet light, exposure to gamma ray radiation, chemical sterilization, or any combination thereof. The chemical sterilization may include sterilization with ethylene oxide.
