    Patent number: 5236390
    Abstract: A mobile medical unit (10) has interior space divided into a service compartment (24), a treatment compartment (26), an entryway compartment (28), and a storage compartment (30). An interior door (52) controls passage of persons between the entryway compartment (28) and the treatment compartment (26), an exterior door (58) controls passage of persons between the entryway compartment (28) and space outside of the medical unit (10), and an opening (64) is formed between the entryway compartment (28) and the storage compartment (30) for retrieval and replenishment of supplies. The interior door (52) and the exterior door (58) form between them an air lock to help maintain an aseptic condition within the treatment compartment (26). However, the interior door (52) is oriented at an acute angle with respect to the exterior door (58) to provide an auxiliary exit for recumbent patients along a smooth curved passageway (94).
