Abstract

This invention is directed towards a patient single surface system, PS3, which is a next generation system solution for patient accommodation, diagnosis, treatment, transfer and transport. PS3 provides a single surface for the patient to remain on from the trauma site through diagnosis, treatment and convalescence. Needs addressed by the PS3 system include improved patient treatment through reduction in time to treatment, reduced or eliminated unnecessary patient movement and injury, as well as improved comfort throughout treatment and convalescence. In addition, the PS3 system solves significant economic considerations.
