Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A dressing which has a physiologically active substance incorporated therein and which comprises: (a) a sealing material comprising (i) a continuous phase comprising a tackifier, and (ii) a discontinuous phase dispersed in the continuous phase and comprising one or more water-soluble or water-swellable hydrocolloids, starches or cellulose derivatives or hydrophilic polymers, and (b) a non-adhesive water-tight film or other water-tight cover material on the surface of the dressing which in use is to be remote from the the skin of the patient to which the dressing is applied, the physiologically active substance being incorporated in the discontinuous phase.
Claim 2
Dependent Claim
28 words
A dressing as claimed in claim 1 in a form adapted for use in the attachment of incontinence or ostomy equipment, drainers and/or bags for collecting wound secretions.
Claim 3

A method of producing a dressing as claimed in any of the preceding claims which comprises dissolving or dispersing a physiologically active substance evenly in a solution of the substance or substances forming the remainder of the discontinuous phase of the sealing material, subsequently drying the solution and, if necessary, comminuting the dried material to a desired particle size and sieving it to a desired particle size distribution, then kneading or otherwise incorporating the dry particles into a molten or heat-softened mass of components forming the continuous phase of the sealing material and thereafter pouring or rolling the blend thereof to uniform thickness on to a sheet or web of the non-adhesive water-tight material of the dressing.
Claim 9
Dependent Claim
26 words
A method as claimed in claim 8 wherein the solution of the substance or substances forming the remainder of the discontinuous phase is an aqueous solution.
