  • Patent number: 5639378
    Abstract: A dispensing device having a container body defining a solution retaining chamber therein, the container having an outlet for dispensing the solution from the chamber and means for removing a component from the solution as the solution is dispensed from the chamber through the container outlet. A method is provided for administering to a patient a pharmacologically active substance which substance is stable only at a pH value which is extreme in the acidic or alkaline region and at which pH value the substance cannot be administered without causing discomfort and/or injury to the patient. The substance is maintained in a solution or dispersion at the pH at which it is stable until the time of administration. At this time the substance is administered through a chamber containing an ion exchange resin which changes the pH of the solution or dispersion to a value which will not cause discomfort and/or injury to the patient.

  • Patent number: 5431879
    Abstract: A method is provided for the sterilization or disinfection of an object in need of such treatment. The object is immersed in a sterilizing or disinfecting solution containing an antimicrobial effective amount of at least one cationic or at least one anionic antimicrobial agent in the presence of a scavenger element containing a scavenger material which is a cationic exchange resin or an anionic exchange resin. Over a period of time, the scavenger element removes from the solution the cationic or anionic antimicrobial agent at a rate which permits sterilization or disinfection of the object and which prevents undesirable build-up of the antimicrobial agent in or on the object. The object is allowed to remain in the solution for a time sufficient for the scavenger element to remove a sufficient amount of the antimicrobial agent to render the object safe for use for its intended purpose and the object is then removed from the solution.
