Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A process of preparing a viscous aqueous composition comprising a chondroitin sulfate and a metal hyaluronate, useful for protecting both human and animal cell layers and tissues subject to exposure to trauma, which comprises mixing the chondroitin sulfate and metal hyaluronate in aqueous buffer solution, in appropriate relevant proportions to cause a significant increase in viscosity of the mixture.
Claim 2
Dependent Claim
59 words
A process of preparing a viscous aqueous composition comprising a chondroitin sulfate and a metal hyaluronate, useful for protecting both human and animal cell layers and tissues subject to exposure to trauma, which comprises mixing the chondroitin sulfate and metal hyaluronate in aqueous buffer solution, in appropriate relevant proportions to cause a significant increase in viscosity of the mixture.
Claim 3
Dependent Claim
44 words
The process of claim 1, wherein the metal hyaluronate is employed at concentrations from about 0.1 g to about 10 g per 100 ml water, and the chondroitin sulfate is employed at concentrations from about 0.1 to about 10 g per 100 ml water.
Claim 4
Dependent Claim
41 words
The process of claim 1, wherein the metal hyaluronate is selected from sodium hyaluronate, magnesium hyaluronate, calcium hyaluronate and potassium hyaluronate, and the chondroitin sulfate is selected from sodium chondroitin sulfate, potassium chondroitin sulfate, calcium chondroitin sulfate and magnesium chondroitin sulfate.
Claim 5
Dependent Claim
11 words
A viscous, aqueous composition of chondroitin sulfate and a metal hyaluronate.
Claim 6
Dependent Claim
11 words
A viscous, aqueous composition of chondroitin sulfate and a metal hyaluronate.
Claim 7
Dependent Claim
37 words
A viscous, aqueous composition of a metal hyaluronate, at a concentration from about 0.1 g to about 10 g per 100 ml water, and chondroitin sulfate, at a concentration from about 0.1 g per 100 ml water.
Claim 8
Dependent Claim
37 words
A viscous, aqueous composition of a metal hyaluronate, at a concentration from about 0.1 g to about 10 g per 100 ml water, and chondroitin sulfate, at a concentration from about 0.1 g per 100 ml water.
Claim 9
Dependent Claim
42 words
A viscous aqueous composition of at least one metal hyaluronate selected from sodium hyaluronate, magnesium hyaluronate, calcium hyaluronate and potassium hyaluronate, and at least one chondroitin sulfate selected from sodium chondroitin sulfate, potassium chondroitin sulfate, calcium chondroitin sulfate and magnesium chondroitin sulfate.
Claim 10
Dependent Claim
42 words
A viscous aqueous composition of at least one metal hyaluronate selected from sodium hyaluronate, magnesium hyaluronate, calcium hyaluronate and potassium hyaluronate, and at least one chondroitin sulfate selected from sodium chondroitin sulfate, potassium chondroitin sulfate, calcium chondroitin sulfate and magnesium chondroitin sulfate.
