摘要:
A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.
摘要:
A sterilization system using a sterilization process monitoring device which is capable of indicating the efficacy of the sterilization process in an enclosed sterilization container while still maintaining the sealed state of the sterilization container. The process monitoring device comprises at least one biological indicator and/or at least one chemical indicator. Upon completion of the sterilization cycle, the process monitoring device can be advantageously removed from the system to determine chemical and/or biological efficacy of the sterilization process. The removal of the biological and/or chemical indicators does not disturb the sterilized state of the articles inside the sterilization container.
摘要:
A method for cleaning and sterilizing a medical device having a lumen with at least two open ends comprises the steps of: a) providing a container having at least one enclosure separated from the container by an interface, b) placing the device into the container and enclosure across the interface in such a way that one end of the lumen of the device is located in the container and the other end in the enclosure, c) generating a flow of a cleaning solution through the lumen to clean the inner surface of the lumen, d) generating a flow of rinse solution through the lumen to rinse the inner surface of the lumen, e) treating the device with a liquid sterilant, f) vaporizing the liquid sterilant in the container or enclosure thereby simultaneously sterilizing and drying the device, and providing a sterile, dry product without further rinsing. In the method, step f) can be conducted under a diffusion restricted environment, or by reducing pressure to a first predetermined pressure followed by further reducing the first pressure to a predetermined second pressure, or at controlled pump down rate. The method further comprises retaining a predetermined amount of the liquid sterilant in the container and enclosure prior to step f).
摘要:
A method for sterilizing an interior of an article with a diffusion-restricted area therein includes the steps of contacting the interior of the diffusion-restricted area with a source of peroxide, and exposing the device to negative pressure for a time period sufficient to effect complete sterilization of the diffusion-restricted area.
摘要:
A method sterilizes a device having a diffusion restricted area and a non-diffusion restricted area. The method includes the steps of vaporizing a first solution of hydrogen peroxide within the diffusion restricted area and vaporizing a second solution of hydrogen peroxide outside of the diffusion restricted area, with the first solution having a lower concentration of hydrogen peroxide than the second solution.
摘要:
A plasma sterilization process which employs hydrogen peroxide vapor as the precursor for the active species generated during the plasma generation cycle and employs a pre-treatment cycle prior to the plasma generation cycle.
摘要:
A method of reducing the concentration of disinfectant in an environment having a concentration of disinfectant of about 500 ppm or less for a period of time to a lower concentration is disclosed. The method comprises the steps of dehumidifying the environment for the period of time to remove disinfectant, and humidifying the environment with moisture during the period of time to maintain a difference between a lower relative humidity and an upper relative humidity of the environment ranging from about 20 to 50%. A system for decontaminating an environment is also disclosed, comprising a source of disinfectant, a source of moisture, one or more spray generators, and a dehumidifier. A method of decontaminating an environment or enclosure is disclosed, comprising the steps of introducing disinfectant, maintaining liquid disinfectant on surfaces, and dehumidifying the environment to increase the disinfectant concentration is also disclosed.
摘要:
A chemical vapor sterilization process is enhanced by concentrating a germicide via condensation and re-vaporization thereof, exploiting the difference between the vapor pressures of the germicide and its solvent to extract some of the solvent during the condensation process.
摘要:
A method and device provide for delivering fluid for cleaning and/or decontamination to a lumen in a medical device. A tube having a plurality of openings therethrough is inserted into the lumen of the medical device the fluid is flowed through the tube, out of the openings and into the lumen.
摘要:
A foamable instrument pretreatment composition includes hydrogen peroxide in a range of from 0.1% to 15% by weight, a surfactant in a range of from 0.5 to 20% by weight; and a foam boosting agent comprising a silicone of from 0.1% to 10% by weight. It is intended for pre-treating instruments after use in a medical procedure and before they are washed.
