Abstract
A medical pad with a pair of laminated plastic film panels defining a passage therebetween for circulating hot or cold water. The pad has a patient contact panel of long staple absorbent cellulosic fibers, and these fibers are anchored directly to a plastic film panel or are intertwined and locked to similar fibers that are so anchored. For moist therapy, the patient contact pad is wetted immediately before use.
Claims13
A patient treating pad for wet or dry use comprising:
- a pair of superimposed film panels with inner surfaces joined together at selected locations to define a fluid circulating path between the film panels;
- a patient contact panel secured at a surface to surface bond to one of the film panels;
- and said patient contact panel has an outer patient contact surface of exposed elongated liquid absorptive means selected from the group consisting of fibers and filaments that extend into a central portion of the patient contact panel and are anchored to the film panel at the surface to surface bond.
A patient treating pad for wet or dry use comprising:
- a pair of superimposed thermoplastic film panels with inner surfaces joined together at selected locations to define a fluid circulating path between the film panels;
- a nonwoven patient contact panel secured at a heat fusion joint to one thermoplastic panel;
- and said patient contact panel has an outer patient contact surface of exposed long staple liquid absorptive fibers that extend into a central portion of the patient contact panel and are anchored to such panel in a heat fusion joint;
- and such heat fusion joint being superimposed over a heat fusion joint between the inner surfaces of the two thermoplastic panels.
