The Prolonged Field Care site of the Special Operations Medical Association has put up a podcast and slides for setting up a clinic in an unconventional warfare situation for Special Forces Operational Detachment Alpha (SFODA) units. This can probably be adapted for makeshift clinics that can be used by medically trained personnel in the event of various disasters, civil war/disturbance, and other emergent situations. The slides include some layouts for a single treatment bed clinic.
