The Internal bleeding moodle points to a procoagulant or L.R.D. The release item text says a normal L.R.D. greatly reduces internal bleeding when used on the chest, while a Makeshift L.R.D. only slightly reduces it there.
Use the device on the chest
Check which L.R.D. you have before using it. Both descriptions require at least 25 mL of LRD serum to function. A device without enough serum is not ready just because it appears in your inventory.
Open the health panel, use the device on the chest, then inspect the internal-bleeding warning and total blood-loss trend again. Do not substitute an ordinary limb dressing and expect the same effect.
Avoid treating a different problem
A surface wound and internal bleeding can coexist. Treat visible limb bleeding separately. If breathing also worsens and the Hemothorax moodle appears, the game specifically calls for a chest drain; the problem has an additional fluid-accumulation component.
Why not stack everything?
The First Aid course warns that both extremes of blood viscosity cause problems, with very thick blood especially dangerous. That is a reason to monitor the actual state rather than indiscriminately combining clotting items. This page does not claim a universal dose or a guaranteed cure in every preset. Use hemothorax treatment for the chest-drain interaction and circulation basics to interpret the follow-up readings.
