A CT value controller includes a storage means, an input means, and a computing means. The storage means stores a function expressing a relative humidity and a CT value regarding a degradation degree of an anticancer agent, an assumed relative humidity, and a CT setting. The input means inputs a measured relative humidity and a measured ozone concentration at a time of degradation treatment of the anticancer agent. The computing means calculates a corrected CT value increment based on a difference between the measured relative humidity and the assumed relative humidity at every input of the relative humidity and the ozone concentration by using the function. The computing means determines a termination of the degradation treatment of the anticancer agent when an integrated CT value of the corrected CT value increments reaches the CT setting.

CT value controller and anticancer agent degradation apparatus

There are provided an anticancer agent degradation method for protecting medical professionals from exposure to an anticancer agent externally scattered in, for example, a safety cabinet or prescription laboratory, during drug preparation or other circumstance, and an anticancer agent degradation apparatus for use with this anticancer agent degradation method. Anticancer agent flyoff in a safety cabinet, etc. is degraded by exploiting an action of ozone-containing air humidified by humidifying means. A relative humidity of humidified ozone-containing air is preferably greater than or equal to 80%. In controlling degradation treatment on the basis of CT values, a difference between expected humidity and measured humidity is reflected in an increment of CT value to understand the progress of anticancer agent degradation properly.

Provided is an exposure-preventing cap of a novel and simple structure that, by being mounted on a vial, can more reliably inhibit leaking of drug solution to an outside when pulling out and collecting drug solution in a syringe from the vial. An exposure-preventing cap, which is mounted on a mouth of a vial sealed with a rubber stopper, wherein a puncturing hole is formed in a center part of a cap-shaped housing that is attached to a mouth of the vial, and a rubber membrane is arranged at the puncturing hole so as to form an internal space between facing surfaces of the rubber membrane and the rubber stopper. The rubber membrane has a dome shape that is convex facing the rubber stopper.

Exposure-preventing cap

A plug for a container capable of improving air-tightness and liquid-tightness is provided. A plug includes a first split piece having a cylindrical first fitting portion to be mounted on an opening portion of a container body and fitted to an opening portion space of the opening portion, an end wall which blocks one end of the first fitting portion, and a first flange portion extending outwardly in a radial direction of the first fitting portion from the other end thereof; and a second split piece having a second fitting portion which is fitted to the first fitting portion of the first split piece and forms a closed space between the end wall and the second fitting portion and a second flange portion extending outwardly in a radial direction of the second fitting portion therefrom.
