We were a MEDEVAC flight; carrying an organ onboard for the purpose of transplant. Since it was a busy; uncontrolled field; we opted to depart VFR and pickup our IFR clearance in the air. The winds were favoring Runway XX; and there were several aircraft in the traffic pattern. While waiting for two close-in aircraft to land (one on final; and another on base); there was a radio call from an aircraft that was practicing the wrong-way approach to RWY XY. We made a radio announcement of our intention to depart RWY XX ASAP (when the landing aircraft were clear of the runway or out of the way from touch-and-go). The aircraft on the wrong-way final made statement that they would break the approach off early; giving us the indication they understood there was traffic in the pattern. We seen the landing lights of the wrong-way aircraft on a long final for RWY XY; and kept an eye on him the entire time. Our takeoff was announced on the radio; and as we were approaching V1; it was clear that the wrong-way aircraft was still continuing to descend and remain on the approach course. I felt it would have been unsafe to abort at this time; and took the aircraft into the air. Our closure rate was increasing; and it appeared that the inbound aircraft had no intention of breaking off the approach. Once airborne; evasive maneuvering toward the east was required to avoid what could have potentially been a collision course. Concurrently; the other aircraft began a turn to the west (I would estimate that they were less than a mile from the approach end of RWY XY when they began to turn)On our part; we could have waited on the runway longer to observe what the inbound aircraft was going to do. On the other aircraft's part: If there is a number of aircraft in a traffic pattern at an uncontrolled field taking off and landing in the opposite direction that a practice approach is being conducted; it is prudent to either choose a more-appropriate approach/runway and/or establish more defined communications and intentions with the other affected aircraft.
CE525 First Officer reported NMAC with opposite direction landing traffic.
