Port-a-med minor (but actually major) fix

[Paineframe]

There's very few things Medbay can do that a solo doctor out in the field can't, and all of those things are either so super urgent that the patient will likely die in the time it takes to Port-a-Med them or so inconsequential that they can easily be kept stable long enough to drag them back to Medbay. If you could send yourself back along with the patient, it would be useful, but there's really never any good reason for a properly prepared medic to go to the trouble to hand off a patient to someone else.
