Biofoam

Self-sealing Biofoam was a marvel of UNSC medical accomplishment in the 2500's. Biofoam was a space-filling coagulant, antibacterial, tissue-regenerative foam polymer, that is inserted into the skin and even deeper into the body itself. This foam keeps damaged organs in place and helps stop bleeding and hemorrhaging. It is, unfortunately, very painful to use, being described as "burning ants crawling around the wound" or "thousands of tiny knives" stabbing the recipient. It was an improvised medical option when there are no medics available. Normally, bottles of biofoam are found in a Health Pack. Often UNSC medics will use it as a sealing agent during treatment in field hospital.

The only downside is that the effects of biofoam are temporary, and after a time (usually a few hours or so) it simply breaks down. Therefore, normally, it is a form of improvised first aid, used only as a temporary sealant until proper medical attention can be sought.

By October of 2552, the UNSC MJOLNIR Mark VI armor contained automatic biofoam injectors, which negated the need for Spartans to use Health Packs.

Trivia

 * Originally Biofoam was described as being able to "numb pain" in it's description on Mjolnir Mark VI armor, however canonically it has now been contradicted as being a painful way to treat wounds. Additionally it raises the question as to why it does not contain any numbing agents or anesthetic compounds.
 * It could only be the application that is painful, quickly numbs after it settles.
