U.S. Pat. No. 3,677,263: Portable bath capsule.
1. A capsule for administering bed baths, comprising;
an elongated sheath of strong, flexible, fluid tight material dimensioned to accomodate and completely enclose the entire body of the patient excepting the head;
said sheath having a neck opening capable of being closed reasonably tightly about the neck of the patient;
said sheath having a elongated opening dimensioned to admit the body of the patient and said elongated opening having means for fluid tight closure thereof; and
means for admitting fluid to and draining fluid from said capsule;
said sheath having a plurality of layers with air spaces defined therebetween for heat insulation.
2. A capsule according to claim 1 wherein said layers include an outer layer and a thinner inner layer tacked to the outer layer at spaced positions and sealed thereto to define a surface of waffle character with said air spaces between the layers for said heat insulation and also for cushioning the sensitive skin of the patient, the inner layer, by reason of being thinner, being ballooned more than the outer layer when the entrapped air in said spaces is heated by warm bathing fluid, thus accentuating said waffle character of the internal surface.
