The Coagulant Bloom Injector is a single-use autoinjector loaded with a proprietary Lazarus compound designated LP-Heme-7, a synthetic fibrinogen catalyst suspended in a thermally-reactive polymer gel. Upon injection into or adjacent to a wound site, the compound undergoes rapid phase-change, expanding into a semi-rigid foam matrix that mechanically occludes hemorrhaging tissue while simultaneously triggering accelerated platelet aggregation. The entire process takes between four and nine seconds depending on wound depth and vascular involvement, with the foam matrix remaining stable for six to twelve hours before enzymatic breakdown begins.

What distinguishes the Bridesmaid from older field coagulants is its dual-action delivery: a hollow-bore needle deposits the compound deep into cavity wounds while a secondary ring-port floods the surface simultaneously, addressing both internal bleed and external seepage in a single press. The injector casing is constructed from recycled Palladian impact-polymer, matte white with a red grip band — the color scheme that gave it its street name, worn at the threshold between life and death like a bride at the altar. Medics note that the foam sets with a faint organic smell, somewhere between blood and antiseptic, which combat personnel describe as unmistakably associated with survival.

The Bridesmaid is ubiquitous in low-tier field medicine across GLMZ's outer districts. Street surgeons carry them in bundles of six. Corporate security medics carry them as backup to more sophisticated trauma systems. It is the piece of equipment most commonly pressed into the hands of someone who has never used medical gear before and told simply: find the hole, press the button. Its simplicity is its legacy.
