Cadaver preservation systems and methods
View Patent ↗A system and method of preserving cadaveric tissue is provided. The present invention utilizes a preservation fluid having high-dose DMSO, high-dose acetic acid, and isopropyl alcohol. It is believed that the high-dose DMSO serves as a hardening agent while the high-dose acetic acid serves as a softening agent.
1. A fluid for preserving cadaveric tissue, the fluid comprising:
an aprotic solvent in a first amount;
a weak acid in a second amount; and
a non-aldehyde oxygen-containing hydrocarbon in a third amount,
wherein the first amount is about 30% by volume of the fluid, wherein the second amount is about 60% by volume of the fluid, and wherein the third amount is about 10% by volume of the fluid.
2. The fluid of claim 1 , wherein the aprotic solvent is Dimethyl Sulfoxide (DMSO), wherein the weak acid is acetic acid, and wherein the non-aldehyde oxygen-containing hydrocarbon is isopropyl alcohol.
3. The fluid of claim 1 , wherein the aprotic solvent is Dimethyl Sulfoxide (DMSO).
4. The fluid of claim 1 , wherein, excluding any water associated with the weak acid, the fluid is an anhydrous solution.
5. The fluid of claim 4 , wherein the fluid is free of aldehyde.
6. The fluid of claim 1 , wherein the fluid consists of the aprotic solvent, the weak acid, and the non-aldehyde oxygen-containing hydrocarbon.
7. The fluid of claim 6 , wherein the pH of the weak acid is below 4.
8. The fluid of claim 7 , wherein the weak acid is glacial acetic acid.
9. A fluid for preserving cadaveric tissue, the fluid comprising:
an aprotic solvent in a first amount;
a weak acid in a second amount; and
a 140 proof alcohol in a third amount,
wherein the first amount is between about 15% and about 30% by volume of the fluid.
10. The fluid of claim 9 , wherein the aprotic solvent is Dimethyl Sulfoxide (DMSO), wherein the weak acid is acetic acid, and wherein the alcohol is isopropyl alcohol.
11. The fluid of claim 9 , wherein the aprotic solvent is Dimethyl Sulfoxide (DMSO).
12. The fluid of claim 9 , wherein the fluid is free of aldehyde.
13. The fluid of claim 12 , wherein the pH of the weak acid is below 4.
14. The fluid of claim 13 , wherein the weak acid is glacial acetic acid.
15. A method of preserving cadaveric tissue, the method comprising injecting into the cadaveric tissue the fluid according to claim 1 or 9 .
