A simulated airway for training and practicing medical procedures has an upper jaw having simulated teeth, a nasal passage, a tongue, an epiglottis, a larynx, a trachea, an esophagus, and vocal cords. Portions of the airway are reinforced with fabric. A method of making a human airway model for simulation of medical procedures includes sculpting a core for a mold from a resin material, depositing a layer of clay on the core, and placing the core in a mold. The layer of clay is removed and a polymer is injected into the mold.

Disclosed in the present disclosure are a pure polyurethane condom having an adhesive layer, and a method for preparing the condom. The pure polyurethane condom having an adhesive layer at least comprises: a first polyurethane film layer; a polyurethane adhesive layer on the first polyurethane film layer; and a second polyurethane film layer on the polyurethane adhesive layer, wherein the 100% tensile modulus of the polyurethane adhesive layer is 2.5 N/mm.sup.2 or lower, and the structures of the first polyurethane film layer and the second polyurethane film layer are different from that of the polyurethane adhesive layer.
