Abstract: The present invention provides a polymer compound peeling agent usable for peeling as many types of polymer compounds as possible and capable of reducing a burden required for a peeling treatment when a polymer compound having adhered to an adhesion object is peeled. The polymer compound peeling agent for peeling a polymer compound having adhered to an adhesion object contains a photoresponsive liquid crystal material having a phase structure reversibly transitioning between an isotropic phase and a liquid crystal phase due to photoisomerization based on irradiation lights of different wavelengths. When the polymer compound is adhered to the adhesion object, the photoresponsive liquid crystal material is contained in the polymer compound with the phase structure set to the isotropic phase, and the phase structure of the photoresponsive liquid crystal material is allowed to transition from the isotropic phase to the liquid crystal phase by photoisomerization based on the light irradiation.

Abstract: A combination radial artery occluder and wrist splint used to simultaneously immobilize the wrist joint and prevent blood flow through a puncture wound or incision in the radial artery following an invasive medical procedure such as catheterization. The invention generally includes three components: a wrist splint that extends along the distal end of the patient's forearm and the back of the wrist and hand; an adjustable pressure strap attached to the splint that extends around the distal end of the forearm; and an adjustable securing strap attached to the splint that extends around the palm of the patient's hand. The pressure strap includes a pressure pad that is selectively positioned to occlude blood flow through only the radial artery while allowing blood flow through the ulnar artery. During use of the invention, the securing strap is tightened around the palm of the hand to help immobilize the wrist joint.
