Abstract
The invention discloses a tunnel-type hydrogen peroxide sterilization method. The method includes the following steps of preliminary drying of a bottle, pretreating, sterilizing, replacing and later degrading. By vacuumizing the interior of a box and a box pressure-restoring pipeline for replenishing fresh air, most of vaporized hydrogen peroxide is degraded; residual hydrogen peroxide is further degraded in a front/rear buffering portion through laminar flow air, so that concentration 1ppm of hydrogen peroxide outgoing from the plastic bottle of equipment and left by operating personnel of the equipment meets requirements of laws and regulations, production speed is increased, and sterility indicators of the plastic bottle are guaranteed by the clean laminar flow air of the front/rear buffering portion.
Description
Technical field
The present invention relates to a kind of sterilizing methods, the tunnel type hydrogen peroxide sterilizing methods that a kind of residual hydrogen peroxide of bottle that can solve after the prior art sterilizing exceeds standard more precisely.
Background technology
Often run into the Medical Packing Materials that the similar plastics class can not high temperature sterilize in pharmaceutical manufacturing, as the bottle in eye drop.Originally, the eye drop bottle all adopted the method for low temperature or ozonization to be processed.New edition GMP(2010) after rules are promulgated, allly relate to the range of management that the product of showing the sterility test project in the legal medicine standard all is included into sterile production, so most eye drop packaging material just needs sterilization treatment, and low temperature or ozonization are difficult to reach GMP and the " requirement of Chinese pharmacopoeia rules.In the sterilizing scheme of world's medicine making method rule or guide approval, hydrogen peroxide (rear simple VHP) is a kind of appropriate low temperature sterilization method.The vaporized hydrogen peroxide sterilization technology, be utilize hydrogen peroxide at normal temperatures gaseous state have more the advantage of killing the spore ability than liquid condition, through generating free OH
-, for the attack cell component, comprise lipid, protein and DNA, reach complete sterilizing requirement.
At present, though useful vaporized hydrogen peroxide carries out sterilization method to the eye drop plastic bottle body, it is that bottle is put into to dish, enters in the VHP sterilization tank and carries out sterilizing.But it belongs to noncontinuity production, its discharging process can only lean on laminar flow car to shift, and the process of transfer has the risk of cross-contamination, and labor intensity is large, and production efficiency is low.Its major defect: the sterilizing rear substitution time (being degradation time) is longer, can not meet continuous production required.
