Title: Apparatus for closing body cavity of dead body and method of treating dead body
Inventor: OKAMOTO TOSHIKI
IPC: A61F5/44
Filed: 2005-04-21
Abstract: It is intended to develop a hygienic apparatus for closing body cavity aiming at preventing feces in the rectum from leakage via the anus due to the postmortem anal muscle relaxation whereby operations by working staffs or care workers engaging therein can be simplified and the working staffs, the care workers or the surrounding area can be protected from infection due to the leakage of the contents from the body. A swellable blocking member (2), which quickly absorbs moisture and swells about 2.5-fold or more upon contact with the body fluid in the body cavity, is packed in a cylindrical member (3) and inserted as such into a body cavity such as the anus. Then the swellable blocking member (2) is pushed out from the cylindrical member (3) by a rod member (10) and thus left in the body. After quickly absorbing moisture and swelling, it sticks fast to the inner wall of the rectum and inflates the rectum to thereby close the rectal pathway.

Inventor: VARMING POUL
IPC: G02B6/02
Filed: 2005-08-24
Abstract: Refractive index modifications such as e.g. Fiber Bragg gratings in micro-structured fiber are according to an aspect of the invention fabricated by first filling and/or purging the holes of the micro-structured fiber with inert gas or by evacuation and, optionally subsequently sealing the ends.  Alternatively, the ends of the micro-structured fiber may be sealed without a preceding purging or evacuation of the holes. In this way hydrogen or deuterium present in the holes after photosensitizing loading will not react with atmospheric oxygen to form water. Water formed this way would otherwise seriously impair the grating formation process. Bragg gratings and other refractive index structures can thus be fabricated with high quality and predictable specifications in micro-structured fiber. Sealing the fiber ends also prevents in-diffusion of moisture. The invention may e.g. find application in connection with fiber optical sensors, high-power fiber lasers, etc.
