A decontamination system not requiring large-scale equipment and capable of efficiently using a decontamination liquid. Long pipes can be installed for each of multiple rooms to be decontaminated, a decontamination liquid is not present in supply pipes as a residual dead liquid, and a proper amount of decontamination liquid can essentially be supplied for each room to cause no failure of an ultrasonic vibrator. The system employs a decontamination mist and includes a compressed air generating equipment and a decontamination liquid supplying equipment, and each room is provided with primary and secondary mist generating equipment. The conveyance distance of a primary mist supply pipe connecting the primary and secondary mist generating equipment is longer than that of a decontamination liquid supply pipe connecting the decontamination liquid supplying equipment and the primary mist generating equipment.

Decontamination system

A mist supply device configured to decontaminate a target with a proper amount of decontamination agent supplied to the target by converting such agent into a fine mist, and reducing the duration of operations such as aeration to increase decontamination efficiency. The device includes a mist generation means, a mist microparticulating means, and a supply port. The mist generation means converts the decontamination agent into a primary mist and supplies it to the mist microparticulating means, which includes at least one vibration board that is subjected to ultrasonic vibration to generate sound flows from board surfaces by an ultrasound in the vertical direction. The supplied primary mist is subjected to ultrasonic vibration by the sound flows to reduce the primary mist into a secondary mist of smaller size. The generated secondary mist is supplied to the inside of the room through the supply port.

Mist supply device

A decontamination device configured to provide, on a short time scale, uniform decontamination of target articles without using expensive electron accelerators and to decontaminate such articles in large quantities. The device includes a device body composed of a decontamination region and an aeration region, a conveyance means for conveying an article, a mist supply means, a mist control means, and an aeration means. The mist supply means converts a decontamination agent into a corresponding mist and supplies the mist to the inside of the decontamination region. The mist control means includes vibration boards adjacent to internal wall surfaces of the decontamination region, and these boards are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist inside the decontamination region is pressed by acoustic radiation to concentrate the mist on external surfaces of the article conveyed inside the decontamination region.

Continuous decontamination device

A decontamination device devised to accomplish decontamination with a proper amount of decontamination agent by employing a mist control mechanism to concentrate a mist for decontamination on the surface of an article to be conveyed, and to reduce duration of operations such as aeration increase efficiency of decontamination, and a pass box in which the decontamination device is disposed. The device also includes a mist supply means configured to convert a chemical for decontamination into the mist, and to supply the mist to the inside of a working chamber accommodating the article. The mist control mechanism includes vibration boards adjacent to internal wall surfaces of the working chamber, which are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist supplied to the inside of the chamber is pressed by acoustic radiation pressure to be concentrated on external surfaces of the article.

Decontamination device and pass box in which same is disposed

A method for decontaminating a low-temperature article, the method comprising: an applying step including applying a decontamination agent to external surfaces of a low-temperature article and supplying a mist of decontamination agent to a first external surface of said low-temperature article to form a condensed film of the decontamination agent on said first external surface; and a drying step including ultrasonically vibrating vibration boards disposed on a periphery of the low-temperature article to generate sound flows from board surfaces by an ultrasound in a vertical direction, irradiating with ultrasonic waves the low-temperature article with the decontamination agent applied thereto, subjecting said first external surface of the low-temperature article to ultrasonic vibration and acoustic radiation pressure, supplying dry air to the first external surface and drying said first external surface.

Method for decontaminating low-temperature article and a pass box used in same

An incubator which can uniformly maintain a temperature/humidity in a culture chamber and prevent dew condensation from occurring in the culture chamber is provided. Further, an incubator which raises an air pressure in a culture chamber higher than that of the external environment to maintain an aseptic environment and prevents water vapor to be supplied from adversely affecting the inner aseptic environment is provided. An incubator includes a culture chamber including an insulated door and insulated wall, circulating means for circulating air in the culture chamber, temperature regulating means for regulating a temperature of the air in the culture chamber, and humidifying means for humidifying the air in the culture chamber. The humidifying means includes compressed gas generating means for generating a compressed gas, water supplying means for supplying water, a mixed gas-liquid regulator which regulates a mixed gas-liquid having compressed air and the water mixed therein, and a vaporizer which vaporizes the mixed gas-liquid to produce water vapor. Furthermore, the water vapor produced by the vaporizer can be directly supplied to the air circulated by the circulating means without passing through an air filter.

Incubator

The present invention provides a microorganism inspection system that is capable of instantly inspecting individual containers for microorganism contamination of the containers that are filled with or accommodate medicines and the like. The present invention has a supply means for supplying a predetermined amount of clean air to the inside or the outer surface of a container, a collecting means for collecting the air supplied to the container by the supply means, and a detecting means for detecting microorganisms included in the air collected by the collecting means.

Microorganism contamination inspection system

The present invention provides a cleaning-performance evaluation system that can acquire evaluation results in real time as quantitative values without such factors as the experience of evaluators causing variations in evaluations. The present invention includes: a contamination means for administering a mock contaminant to the inside of a work chamber; a waste liquid recovery means for performing a cleaning operation and recovering a cleaning waste-liquid that contains the mock contaminant; a mist generation means for generating a mist of the cleaning waste-liquid; a collection means for collecting inspection air that includes the generated mist; and a detection means for detecting the amount of the mock contaminant included in the inspection air collected by the collection means. The present invention evaluates the cleaning operation by confirming that the amount of the mock contaminant detected by the detection means is at or below a prescribed value.
