Patent number: 7210482Abstract: A face mask structure has an upper mask portion, a middle mask portion, and a lower mask portion, which are formed integrally. The upper mask portion has an upper metal stripe disposed at a proper position thereof. The lower mask portion has a lower metal stripe disposed at a proper position thereof. The upper and lower mask portions are folded in opposite directions. When in use, the upper and lower mask portions are spread out to support the middle mask portion. In this way, the face mask structure becomes fitting in with the shapes of human faces. Furthermore, the middle mask portion has multiple folding portions. When in use, the folding portions are stretched out to increase filtering area. Thereby, the inner space of the face mask structure is increased, the air-invasion rate is reduced, and the filtering efficiency is thus improved.Type: GrantFiled: December 8, 2005Date of Patent: May 1, 2007Assignees: Taiwan Textile Research Institute, Champak Enterprise Co., Ltd.Inventors: Po-Hsiung Huang, Cheng-Kun Chu, Hung-En Chen, Jing-Tyr Lin, Jen-Hsiung Lee

Patent number: 7178519Abstract: A novel connection device, and method for its use, for connecting a volume displacement detection device and a gas composition detection device in line with an intubation tube is disclosed. The connection device allows a user to combine two systems commonly employed by medical personnel to assess the location of an intubation tube placed into a patient. The two systems have alternate means of assessing the location of an intubation tube in a patient and therefore, when combined into a single unit via the connection device, improve the accuracy of placing a tube in a desired location while reducing or eliminating complications associated with misplacement. A kit comprising components that may be assembled to provide a device for assessing the proper placement of an intubation tube in a patient is also disclosed. The kit may be used in any environment, but is particularly well suited for emergency, pre-hospital settings requiring intubation where quick assembly of the components is essential.Type: GrantFiled: November 21, 2002Date of Patent: February 20, 2007Assignee: University of Florida Research Foundation, Inc.Inventors: Richard Melker, Dietrich Gravenstein, Andrea Gabrielli
