Publication number: 20110244170Abstract: A thermally formed three-dimensional mesh fabric comprises a flexible three dimensional permeable sheet and a thermally formed cover. The flexible three dimensional permeable sheet has a surface and a softening temperature. The thermally formed cover is applied to at least a portion of the surface of the three dimensional permeable sheet, is low-temperature thermoplastic polyester and has a softening temperature lower than that of the three dimensional permeable sheet. Thus, thermal forming three-dimensional mesh fabric is permeable, lightweight and has good support and is suitable for applications such as splints, plaster bandages and safety protectors.Type: ApplicationFiled: April 2, 2010Publication date: October 6, 2011Inventors: Sun Fu Hsu, Mei Jan Chu, Kuo Hsiung Wang, Yi-Che Huang, Qi-Wen Lu, Chien-Cheng Lin

Publication number: 20090042242Abstract: The present invention provides a two-step Gram staining method. The method is conducted by using a clean slide, followed by adding 10˜30 ?l primary stain from a reagent kit, adding an equivalent amount of specimens uniformly on said slide without drying and frame fixing, then immediately adding 30˜60 ?l counter-stain on said slide for incubating 15 seconds, rinsing with water, and finally examining under a microscope, the result appears color contrast on the center of the slide between the Gram-negative bacteria performing light red color and the Gram-positive bacteria performing deep purple color.Type: ApplicationFiled: May 30, 2008Publication date: February 12, 2009Inventors: YING YE, TAO YUAN, LI-XIN YANG, FENG-QI WEN
