Abstract: An electroplatable high-density plastic comprises cerium oxide and at least one of polyphenylene sulfide (PPS) and high-rigidity nylon (MXD6). The polyphenylene sulfide and high-rigidity nylon make the article made of the electroplatable high-density plastic electroplatable, such that a metal layer can be electroplated thereon to give a metallic luster. Simultaneously, the polyphenylene sulfide causes the article to have a metal-like crisp sound when colliding. In addition, the cerium oxide can increase the density of the electroplatable high-density plastic, and confer the articles made of the electroplatable high-density plastic the properties of hard texture, thereby resulting in the advantages of folding and scratch resistance and low hygroscopicity, which not only expands the application range of the articles made of the electroplatable high-density plastic, but also enhances the value thereof.

Abstract: A pharyngeal intubation guiding device includes lengthwise extending tongue-side and palate-side walls that cooperatively define a guiding duct. The tongue-side wall is configured to conform to the rear end of a patient's tongue to permit the guiding duct to confront the opening of the patient's larynx. The palate-side wall has an outer contour which establishes a guideway towards the opening of the patient's esophagus. A lengthwise extending laryngoscope guiding channel and a lengthwise extending endotracheal tube guiding groove are disposed in the guiding duct. A viewing window is disposed to define a terminal end of the laryngoscope guiding channel. The endotracheal tube guiding groove has a lead-in port to permit an endotracheal tube introduced therein to be removable laterally. A lengthwise extending conduit is disposed in the guiding duct to permit an aspirator tube to reach the patient's trachea to suck out phlegm.
