Abstract
A method and an apparatus are provided for cleaning, disinfecting, and/or sterilizing a device. The method comprises contacting an object with an obstructing substance such that the object is infiltrated with at least a portion of the obstructing substance. An absorptive and/or adsorptive capacity of the object is reduced by the obstructing substance. The object is contacted with a treatment agent after the capacity of the object is reduced. Infiltration of the object with the treatment agent is limited by the reduction of the capacity of the object.
Claims24
A method for reduction of residuals comprising:
- contacting an object comprising a polymer with a water composition, such that the object is infiltrated with at least a portion of the water composition, wherein a capacity of the object is reduced by the water composition, the capacity selected from at least one of absorptive and adsorptive capacity;
- and
- contacting the object with a hydrogen peroxide composition that is separate from the water composition, wherein infiltration of the object with the hydrogen peroxide composition is limited by the reduction of the capacity of the object;
- and
- removing at least a portion of the hydrogen peroxide composition from the object, wherein after the removal of the hydrogen peroxide from the object, a first residual content of the hydrogen peroxide remaining on a surface of the object is less than a second residual content of the hydrogen peroxide remaining on the surface of the object if the object was not contacted with the water composition prior to contacting the object with the hydrogen peroxide.
A method for reduction of residuals comprising:
- contacting an object with a gaseous water composition, wherein the gaseous water composition comprises a liquid or a mist, such that the object is infiltrated with at least a portion of the gaseous water composition, wherein a capacity of the object is reduced by the gaseous water composition, the capacity selected from at least one of absorptive and adsorptive capacity;
- contacting the object with a gaseous hydrogen peroxide composition that is separate from the gaseous water composition to disinfect the object, wherein infiltration of the object with the gaseous hydrogen peroxide composition is limited by the reduction of the capacity of the object;
- and
- removing at least a portion of the gaseous hydrogen peroxide composition from the object, wherein after the removal of the gaseous hydrogen peroxide composition from the object, a residual content of the gaseous hydrogen peroxide composition remaining on a surface of the object is less than or equal to 1,500 ppm/cm2 by weight.
A method for reduction of residuals comprising:
- contacting an object with a water composition, such that the object is infiltrated with at least a portion of the water composition, wherein a capacity of the object is reduced by the water composition, the capacity selected from at least one of absorptive and adsorptive capacity;
- and
- contacting the object with a hydrogen peroxide vapor that is separate from the water composition, wherein infiltration of the object with the hydrogen peroxide vapor is limited by the reduction of the capacity of the object;
- and
- removing at least a portion of the hydrogen peroxide vapor from the object, wherein after the removal of the hydrogen peroxide from the object, a first residual content of the hydrogen peroxide remaining on a surface of the object is less than a second residual content of the hydrogen peroxide remaining on the surface of the object if the object was not contacted with the water composition prior to contacting the object with the hydrogen peroxide.
