Abstract
Abstract A contoured inner bathing tub or litter having a multiplicity of perforations or apertures formed therein is removably positioned within a complementarily contoured outer tub. The outer tub is supported on a mobile frame. The present invention permits a patient to be easily positioned on the litter and, then, bathed while resting stationary and in a natural position within the inner tub. The perforations enable the bathing liquid to enter the litter for washing the patient.
