Abstract

A system for transferring patients to and from emergency medical vehicles and for securing the patients within the vehicles during transport is particularly adapted for helicopters, with at least two stations within the helicopter for securing two patients therein. The system accommodates standard stretchers or patient litters, including a first litter positioned in the first station in the rear of the aircraft approximately aligned with but above and behind the second patient station. In order to load the patients into the separate stations, interlockable trays and support plates are used. An upper tray is initially telescoped within a lower tray which, in turn, is supported on a carriage and lift assembly. The lower tray can be swung relative to the lift assembly to an oblique position pointed toward the exterior door of the helicopter. In addition, the lower tray, with the upper tray supported thereon, can be raised so that the upper tray can be slid rearward into the second station. Each tray has mechanism for locking a patient litter securely in the tray.

Claims4

Dependent claims

An apparatus for positioning and securing a patient support relative to an interior of a vehicle having a floor comprising;

a first tray for removably receiving the patient support wherein the patient support can be secured to said first tray for transportation of the patient;
and
a first base on the floor of the vehicle, said first tray being removably, telescopically connected to said first base such that said first tray can be telescopically, longitudinally extended relative to said first base, said first tray being pivotally attached to said first base for pivotal movement of said first tray, said first base including means for vertically lifting and lowering said first tray relative to the floor, wherein said first base includes a foundation member and a second tray, said second tray being located between said first tray and said foundation member such that said first tray and said second tray are removably, telescopically connected whereby said first tray can be telescopically, longitudinally extended relative to said second tray, and wherein upon telescopic, longitudinal extension of said first tray relative to said second tray, said first tray is removable from said second tray and is securable in said vehicle at a location remote from said second tray and said first base for sequential loading of more than one patient support.
