Fairly long-time lurker on the forums here. Quick question:

Is it possible to create an item that acts something like the Unitec med packs that, instead of healing the actor nearby, stops all of its wounds from bleeding? I imagine it might be done by stopping the emitters somehow or deleting them entirely, though I'd prefer to have the wounds themselves stay, just stop doing damage to the actor.

I'm not sure how one would go about plugging up only the bleeding from wounds and actually leaving the wounds intact like scars, but there are work arounds for stopping up bleeding.
This is CaveCricket48's mod slightly altered to suit your description.

The original mod is here.

edit: the mod below does not actually patch up or get rid of the wounds of the person. What it does instead is deletes your guy and spawns a new guy in his place with the exact same inventory and hp.

Thanks for the reply, ry. It does the job perfectly. ;3
