Problems solved by technology

[0006] In the method based on the hydrogen peroxide low-temperature gas, although the required level of sterilization effect can be obtained, a certain degree of processing time is required in order to sterilize the whole package, and when the hydrogen peroxide low-temperature gas passes through When the upper surface seal made of TYVEK (trademark) penetrates into the inside of the plastic label, there is a problem that it takes time to remove the condensed hydrogen peroxide inside

Embodiment Construction

[0089] In the present invention, "sterilization" is used in a broad meaning including the concept of "decontamination" in addition to the original concept of "sterilization". Here, the original "sterilization" is defined according to the "Guidelines related to the manufacture of sterile medical products based on aseptic technique" (the so-called Japanese version of aseptic technique guidelines), and is defined as "the , to kill or remove all types of microorganisms, thereby obtaining a state in which no microorganisms exist in the target substance."

[0090]On the other hand, "decontamination" is defined as "a condition in which living microorganisms or fine particles are removed or reduced to a pre-specified level by a reproducible method" according to the above-mentioned Japanese version of the Aseptic Practice Guidelines.

[0091] Here, from the concept of probability, the number of bacteria cannot be made zero, so in practice, a sterility assurance level (SAL: Sterility As...

Abstract

Provided is an electronic beam irradiation device that is able to: use a compact, low-energy electron accelerator with a narrow irradiation window to irradiate an electronic beam uniformly on the entire outer surface of an object for irradiation; keep the reliability and safety of sterilization performance high by making the sterilization level of each of multiple sites substantially the same; and reduce electron accelerator cost, and by extending usage limit (life), equipment initial cost and maintenance cost. The invention comprises an electron beam irradiation means forming an electron beam irradiation area, and a gripping / moving means that grips part of the object for irradiation, and passes said object through the inside of the electron beam irradiation area. The entire surface of the object for irradiation is capable of uniformly passing through the electron beam irradiation area by combining regripping of the object for irradiation by means of two gripping mechanisms that the gripping / moving means is provided with, rotating of the object for irradiation by means of two rotating mechanisms, and moving of the object for irradiation by means of two movement mechanisms.

Description

technical field [0001] The present invention relates to an electron beam irradiation device for sterilizing the outer surface of a package containing sterilized articles by electron beam irradiation, and conveying the sterilized package to a working room in an aseptic environment. Background technique [0002] Prefilled syringes, prefilled vials, and the like filled with medical products in advance have been manufactured for convenience at medical sites. The work of filling the above-mentioned syringes, vials, etc. with medical products is performed in a filling work room (hereinafter referred to as aseptic work room) under an aseptic environment. The syringes and vials used in this work are relatively small items, and a large number of them need to be handled. Therefore, the above-mentioned syringes, vials, etc. are sterilized by gamma ray irradiation, electron beam irradiation, EOG (ethylene oxide gas) and the like in each manufacturing stage, and a predetermined number o...
