Title: Ostomy Pouch
Inventor: KEYES DENIS E
IPC: A61F5/443
Filed: 1994-02-07
Abstract: The ostomy pouch has a coupling or securement member formed as a washer-shaped wafer of adhesive material, preferably a hydrocolloid.  The pouch is secured directly onto the abdominal wall with the adhesive wafer aligned with the stoma.  Flushability of the pouch is enhanced by forming the pouch with converging side walls within an optimum angular range and a predetermined pouch width and pouch height.  The pouch also has a predetermined wall thickness and the wafer is of predetermined thickness.  Thus when the pouch is deposited in a water-saver toilet, bottom end first in a carrier sleeve, the pouch can flow in streamlined fashion through the passages of a toilet and any sewer pipe or septic line connected to the toilet.  If the flush capacity of the toilet and the flow rate of water through the toilet and sewer line are increased, the ostomy pouch can be deposited in the toilet without a carrier sleeve.

Title: Fluorescent labeling complexes with large stokes' shifts formed by coupling together cyanine and other fluorochromes capable of resonance energy transfer
Inventor: WAGGONER ALAN S
IPC: G01N33/533
Filed: 1996-06-05
Abstract: The present invention provides low molecular weight fluorescent labelling complexes with large wavelength shifts between absorption of one dye in the complex and emission from another dye in the complex. These complexes can be used, for example, for multiparameter fluorescence cell analysis using a single excitation wavelength. The low molecular weight of the complex permits materials labelled with the complex to penetrate cell structures for use as probes. The labelling complexes are synthesised by covalently attaching through linkers to form donor-acceptor complexes. Resonance energy transfer from an excited donor to fluorescent acceptor provides wavelength shifts up to 300nm. The fluorescent labelling complexes preferably contain reactive groups for the labelling of functional groups on target compounds, such as derivatised oxy and deoxy polynucleic acids, antibodies, enzymes, lipids, carbohydrates, proteins and other materials. The complexes may contain functional groups permitting covalent reaction with materials containing reactive groups.
