Kits, compositions and methods for wound treatment and management
The inventive subject matter provides compositions and methods for transiently or permanently treating or managing an injury. Contemplated compositions are polymerizable in situ over short time periods, even in the presence of blood, without undue exothermic heat. Contemplated compositions may further comprise an anesthetic, an antiseptic, an adhesion promoter, and/or a vasoconstrictor.
1. A method for affixing a non-tissue material to skin of a person, comprising:
applying a polymerizable composition to the skin of the person;
contacting the polymerizable composition with the non-tissue material while the polymerizable composition polymerizes to so affix the non-tissue material to the skin;
wherein the polymerizable composition comprises a silicone mixture, and wherein the silicone mixture comprises
(a) a vinyl end-blocked polydimethylsiloxane as a first silicone elastomer component and a platinum catalyst, and
(b) a vinyl end-blocked polydimethylsiloxane as a second silicone elastomer component and a trimethyl end-blocked methyl-hydrogen siloxane polymer as a silicone crosslinker; and
(c) wherein the polymerizable composition comprises a first and a second adhesion promoter that synergistically enhance adhesion of the polymerized composition to the skin, and wherein the first and second adhesion promoter are N-(triethoxysilylpropyl)-O-polyethylene oxide urethane and tetrapropoxysilane.
2. The method of claim 1 wherein the non-tissue material is selected from the group
consisting of a silicon sheet, medical tubing, silicon tubing, cloth, gauze, and a medically acceptable wound cover.
3. The method of claim 1 wherein the non-tissue material is pretreated to facilitate bonding of the non-tissue material.
4. The method of claim 1 wherein the polymerizable composition polymerizes in the presence of blood.
5. The method of claim 1 wherein the polymerizable composition forms an elastic seal upon polymerization.
6. The method of claim 5 wherein the seal is removable.
7. The method of claim 1 wherein the polymerizable composition polymerizes within two minutes.
8. The method of claim 1 , wherein the silicone mixture has a work time of between 30-90 seconds and a cure time of between 1-5 minutes.
9. The method of claim 1 , wherein the first and second adhesion promoter allow for adhesion of the polymerized composition to the skin over a period of at least 10 hours.
10. The method of claim 1 , wherein the composition further comprises at least one of an antiseptic, fumed amorphous silica, and a thixotropic agent.
11. A polymerizable composition, comprising:
a silicone mixture, wherein the silicone mixture comprises
(a) a vinyl end-blocked polydimethylsiloxane as a first silicone elastomer component and a platinum catalyst, and
(b) a vinyl end-blocked polydimethylsiloxane as a second silicone elastomer component and a trimethyl end-blocked methyl-hydrogen siloxane polymer as a silicone crosslinker; and
(c) wherein the polymerizable composition further comprises a first and a second adhesion promoter that synergistically enhance adhesion of the polymerized composition to skin, and wherein the first and second adhesion promoter are N-(triethoxysilylpropyl)-O-polyethylene oxide urethane and tetrapropoxysilane.
12. The composition of claim 11 , wherein the silicone mixture has a work time of between 30-90 seconds and a cure time of between 1-5 minutes.
13. The composition of claim 11 , wherein the composition is formulated to adhere, upon polymerization, to skin over a period of at least 10 hours.
14. The composition of claim 11 , further comprising at least one of an antiseptic, an antibacterial agent, an analgesic agent, a vasoconstrictor, fumed amorphous silica, and a thixotropic agent.
15. The composition of claim 11 , wherein the composition polymerizes to form a seal having a hardness of between 0 on the Shore 00 durometer scale and 40 on the Shore A durometer scale.
16. The composition of claim 11 , wherein the composition polymerizes to form a seal having a hardness of between 10 on the Shore 00 durometer scale and 30 on the Shore A durometer scale.
17. The composition of claim 11 , wherein the composition polymerizes to form a seal having a hardness of between 15-25 on the Shore A durometer scale.
18. The composition of claim 11 , wherein the composition polymerizes to form a seal having an elongation at break of between 200-800%.
19. The composition of claim 11 , wherein the composition polymerizes to form a seal having a tensile strength of between 100-2000 psi.
20. The composition of claim 11 , wherein the vinyl end-blocked polydimethylsiloxane and the platinum catalyst are enclosed in a first container, wherein the vinyl end-blocked polydimethylsiloxane and the trimethyl end-blocked methyl-hydrogen siloxane polymer are enclosed in a second container that is separate from the first container.
