摘要:
A dispensing and application apparatus designed to contain pre-measured amounts of a flowable substance. The apparatus comprises a compartment 130 for storing the substance that is partially enclosed by a frangible seal 210, an applicator 100, and an expandable chamber 170 designed to accept and dissipate the hydraulic force created when pressure is applied to the compartment 130, rupturing the frangible seal 210, and expelling the substance into the chamber 170. The applicator 100 is attached to the chamber 170 with an applicator bond area 180. The expandability of the chamber 170 is conferred by expandability of the applicator 100, and is varied in different embodiments by altering the ratio between the area of the applicator bond area 180 and the area of the applicator 100. The frangible seal 210, in one of many embodiments, may be a chevron shape stress riser 250 with a point of inflection 240 oriented towards the compartment 130. A removable cap may cover the applicator.

An ostomy appliance including a collection pouch and a faceplate, each equipped with a flexible plastic coupling ring for detachably joining the faceplate and pouch. One of the rings includes a neck portion that protrudes through the opening of the other ring when the two are coupled together. An annular web of thin, flexible, stretchable plastic material is secured to the backside of the receiving ring and sealingly engages the protruding end of the neck portion when the two rings are latched together.

An ostomy appliance including a collection pouch, an adhesive faceplate for adherence to a patient, and a coupling ring assembly detachably connecting the pouch and faceplate together. The coupling ring assembly comprises a pair of flexible plastic latching rings capable of being connected together by axially-applied forces and a soft, deformable, sealing ring interposed between, and axially compressed by, opposing wall portions of the latching rings.
摘要:
A collection pouch for use by ostomates, the pouch being drainable to facilitate extended use of the pouch and including a gas venting and filtering assembly having a replaceable deodorizing filter element. A barrier film is disposed within the pouch to protect the filter element from contact with and possible obstruction by exudate. Interior wall surface areas of the double-chambered pouch are raised or embossed, and the filter assembly is internally ribbed, to insure that the pathway for the escape of gases from the pouch remains open.

Apparatus, systems and methods are disclosed for treating a biological fluid with light. A container of biological fluid is introduced into a fluid treatment chamber where it is contacted with light provided by one or more light sources in proximity to the fluid treatment chamber. A drawer for holding containers of biological fluid introduces the containers into the chamber. Containers for holding the biological fluid are marked by the apparatus to indicate the status of the treatment.

The invention herein provides an improved manufacturing process for sterile containers pre-filled with topical antimicrobial solutions that reduces or avoids undesirable by-products as a result of the ethylene oxide gas sterilization technique. The process of the invention produces containers pre-filled with antimicrobial solution that are sterilized in accordance with the ethylene oxide technique, while at the same time have a toxic residue content within acceptable limits. The invention is particularly useful in the manufacture of plastic containers pre-filled with iodine-based antimicrobial solutions.
