Abstract

This invention discloses medical bandage devices for venous leg ulcer treatments and long distance travelers on transportations such as trains and planes. The devices utilize the recovery force generated by a shape memory polymer (SMP) or SMP/composite strips to produce a static pressure profile to help blood circulation, hence to speed up the healing process of a venous leg ulcer. The invention discloses the structures of the bandages, which may consist of a single layer or multi-layers, with SMP in sheet or strips form and SMP as a single layer or integrated into fabrics, the structure of the bandage device, and the manufacture methods to produce the SMP-based bandage devices. The stimulus which is used to actuate the SMP may include, but not exclude, heat, UV- or infrared-light, RF microwave, chemical or even water. The SMP may be selected from thermoplastic and thermoset (covalently cross-linked) polymeric materials. Such polymeric materials include polymers based upon polyurethane, polystyrene, polynorbornene, polyethyleneterephthalate, polyethyleneoxide, poly(1,4-butadiene), poly(Tetrahydrofuran) and ABA triblock copolymers made from poly(2-methyl-2-oxazoline)-based SMPs and a biodegradable SMP such as oligo-(ε-caprolactone)diol and crystallisable oligo-(&rgr;-dioxanone)diol.
