Application No. 08/345,215
said flexible walls comprising two different sheets located in two portions of the
package for permitting the introduction of different sterilizing agencies into said portions
of the package where said two different sheets are located,
said sheets including
(a) a first flexible sheet for allowing the introduction therethrough of a first
sterilizing agency,
(b) a second sheet for allowing the introduction therethrough of a second
sterilizing agency, and
(c) said second sheet has a different composition from said first sheet,
a pressure-rupturable seal between the superimposed walls of said package,
said seal extending from the first edge of the package to the second edge to divide said
package into two separate compartments,
a dry wound dressing in one compartment,
water in the other compartment,
said pressure-rupturable seal being able to be forced open by manual pressure
applied to the exterior of the package by pressing on the water-containing compartment
of the package with the hands to increase the hydrostatic pressure in the water-
containing compartment and thereby force the water through the rupturable seal into the
dry wound dressing contained in said one compartment to form a fluid dispersion for
being dispensed from the package onto the wound,
whereby said dry wound dressing is sterilized by a first sterilizing agency
introduced into the package through the first sheet and the water sterilized by a second
sterilizing agency introduced into the package through the second sheet.
19. A mixing and dispensing package for applying a wound dressing product to a
patient, comprising:
a flexible container-body formed from superimposed upper and lower flexible
walls that comprise a flexible pouch having first and second edges on opposite sides of
the package,
the upper and lower flexible walls of the package have an ionomer coating on an
inside surface thereof,
a rupturable seal in the package comprising a heat seal wherein the ionomer
coating is bonded to itself to define a pressure-rupturable seal between the
superimposed walls of said package with the ionomer coating, said seal extending from
the first edge of the package to the second edge to divide said package into two
separate compartments,
a dry wound dressing in one compartment,
water in the other compartment,
said pressure-rupturable seal comprising the ionomer being able to be forced
open by manual pressure applied to the exterior of the package by pressing on the
water-containing compartment of the package with the hands to increase the hydrostatic
pressure in the water-containing compartment and therefore the water through the
rupturable seal into the dry wound dressing contained in the second compartment,
a portion of the package being removable to provide an opening through which
the dressing can be dispensed for being applied onto the wound,
