Problems solved by technology

[0006] In the method based on hydrogen peroxide gas, although a required level of sterilization effect can be obtained, a certain degree of processing time is required to sterilize the entire package, and when hydrogen peroxide gas is passed through Tyvek ( Tyvek) (trademark) when the top surface seal member enters the inside of the plastic barrel, there is a problem that it takes time to remove the hydrogen peroxide condensed inside

Abstract

Provided is an electron beam irradiation device that is capable of uniformly irradiating the entire outer surface of a container with electron beams using small-sized low-energy electron accelerators,and is able to maintain the reliability and safety of the sterilization effect at high levels by sterilizing each part to be sterilized to equal degrees, and is also able to keep the initial costs and maintenance costs of the device low by reducing the costs of the electron accelerators and extending the usage limit (service life) of the electron accelerators. When the side surface portions of the container are irradiated with electron beams with the bottom surface portion of the container supported by a support means, the position of the container is moved by the support means so that the distances between the side surface portions of the container and irradiation windows of the electron accelerators are substantially equal. Next, when an upper surface portion and the bottom surface portion of the container are irradiated with electron beams with the side surface portions of the container held by a holding means, the position of the container is moved by the holding means so that thedistances between the upper surface portion and the bottom surface portion of the container and the irradiation windows of the electron accelerators are substantially equal.

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 transporting the sterilized package to a working room in a sterile environment. Background technique [0002] Prefilled syringes, prefilled vials, etc. that are prefilled with pharmaceuticals are manufactured for the convenience of medical sites. The work of filling the above-mentioned syringes, vials, etc. with pharmaceuticals is performed in a filling work room (hereinafter referred to as "sterile work room") under an aseptic environment. The syringes, medicine bottles, and the like used in this work are small items, and a large number of them need to be handled. Therefore, these syringes, vials, etc. are sterilized by gamma ray irradiation, electron beam irradiation, EOG (ethylene oxide gas) etc. at each manufacturing stage, and are packaged in a predetermined number in a...
