摘要:
A method and an apparatus for sterilizing a lumen device. A lumen and a container having an interface on a wall of the container are enclosed in a chamber. The lumen is placed across the interface so that one end of the lumen is in the container and the other end is in the chamber. Germicide is introduced into the chamber, and a pressure difference is created between the two ends of the lumen, so that the germicide flows through the lumen. The lumen may alternatively be placed across an interface which separates the chamber into two areas. Germicide is introduced into the chamber, and a pressure difference is created between the two areas of the chamber, causing the germicide to flow through the lumen.

A sterilization container holds instruments during a sterilization process. It has en enclosure with an opening into the enclosure. A self-closing mechanism at the opening keeps the opening closed when not attached to a sterilant delivery source.

A device and a method for rapidly determining the effectiveness of sterilization or disinfection processes are provided. The method involves contacting a biological indicator containing a known number of live spores to a sterilization or disinfection process. When the spores are killed, the minerals in the spores are released. Water is contacted with the dead spores to form an aqueous solution. A parameter related to the concentration of a mineral in the aqueous solution is measured. The effectiveness of the germicidal process is determined from the parameter and the initial number of spores in the biological indicator. Measuring the parameter by measuring the conductivity of the aqueous solution is particularly effective and sensitive.

A sterilization system employs a mist of chemical sterilant to sterilize devices such as medical instruments. A partial vacuum enhances dispersion of the mist into a sterilization chamber.
摘要:
A method and an apparatus are disclosed to reduced or eliminate the occlusion of the device in the container during the cleaning or sterilizing process, preferably with the use of a support and a controllable opening or interface. By changing the configuration of the support, the contact pattern between the device and the support can be modified to reduce occlusion during a cleaning, disinfecting or sterilization procedure.
摘要:
A system and a method for sterilizing a lumen device involve a container in a chamber and a source of germicide. The container has an interface separating the container into two compartments and a communication port which provides fluid communication between the container and the chamber. The lumen device extends across the interface, and the two compartments are in fluid communication with each other through the lumen device. The lumen device is sterilized when the germicide flows from compartment to compartment through the lumen device.

A method for sterilizing medical devices and similar instruments in diffusion-restricted containers is provided. The sterilization method includes placing a liquid solution containing vaporizable germicide such as hydrogen peroxide into the diffusion-restricted container and vaporizing the germicide. The containers can be attachable and detachable to a sterilization system, and used as a vacuum chamber. An attachable/detachable container containing an article to be sterilized can be nested with a second container, and the article and inside and outside of the inner container are sterilized. The sterile article inside the nested containers can be transported and the sterile inner container with the sterilized article can removed from the outer container and placed in a sterile environment without contaminating the sterile environment. The sterile article can then be removed from the sterile container and utilized. Alternatively, the sterilization method may include introducing germicide vapor into an attachable/detachable container.
摘要:
A monitor of the concentration of an oxidative gas or vapor comprises a chemical coupled to a temperature probe, such as by a carrier. Addtionally, the monitor is used in a method of monitoring the concentration of an oxidative gas or vapor and in a sterilization system operated by a user. By utilizing an output signal from the temperature probe to measure the heat produced in an exothermic reaction between the monitored oxidative gas or vapor and the chemical of the monitor, the concentration of the monitored oxidative gas or vapor can be determined. The present invention represents an improvement over the monitors described in the prior art since it is more simplified, and can provide information on the local concentration of an oxidative gas or vapor at various positions within a chamber, and can be operated in size-restricted volumes. Additionally, a method of using the monitor is described, as well as a sterilization system which utilizes the monitor.
