Abstract: An ostomy pouch is disclosed in which a flexible, shape-recoverable plastic dome is secured internally to a wall of the pouch over a vent opening. A peripheral portion of the dome spaced from the apex is provided with at least one slit therethrough traversing a radially and axially extending plane of the dome. The slit is curved or arched towards the apex and defines outer and inner lips that normally have their opposing edges in juxtaposition to restrain the escape of gases from the pouch but permit such escape in quantity when the apical portion of the dome is depressed (by axially squeezing the dome). The lips advantageously have beveled opposing surfaces with the surface of the outer lip generally facing towards the vent opening and that of the inner lip generally facing away from the vent opening.

Abstract: Vented ostomy pouches are disclosed in which a first wall is securable to a patient's peristomal skin surfaces and the obverse second wall is provided with an outlet opening for the escape of gases from the pouch. A deodorizing gas filter extends over the outlet and a third wall, or internal barrier wall, is located within the pouch and divides it into two chambers. The barrier wall operates to block the passage of solids and most liquids from the first chamber to the second but is provided with at least one vent that permits the flow of gases into the second chamber from the first. A filter-protecting panel in the second chamber directs such gases along a circuitous route as they travel from the vent to the outlet. A connection, preferably in the form of a spot weld, joins the barrier wall to the bodyside first wall of the pouch at about the elevation of the filter to prevent the barrier wall from blocking against other surfaces and obstructing the flow of gases through the vent and filter.

Abstract: A fume hood includes a housing with a work chamber, an access opening to the work chamber, and a sash that one may move between raised and lowered positions to open or close the access opening. It also includes a counterbalance system that maintains the sash at a desired position between two predetermined limits. An adjusting weight system reduces the weight provided by the counterbalance system or increases the weight of the sash to allow the sash to drop to a predetermined position after it has moved above that predetermined position.

Abstract: A thermal blanket particularly suitable for post-operative treatment of body joints such as the shoulder, ankle, knee and elbow. The blanket includes a bodyside first panel composed of double layers of thermoplastic sheet material heat-sealed together to define at least one and preferably two serpentine fluid flow passages for the circulation of cooling (or warming) fluid. The blanket also includes a soft, foldable exterior second panel coplanar with the first panel, the edges of the two panels being secured together to form a unitary, easily-foldable blanket. The exterior panel is of soft loop-providing pile fabric over substantially the entire exterior surface thereof.

Abstract: A hair clip includes a base plate (1) secured to an ornamental cover and a pair of hooking arms (13) extending from the base plate, in which each arm has an extension protruding from an outer edge at the base portion of the arm. The extensions (13c) come into a sliding contact with an engaging part (4b) of a hair retainer (4) when it is moved towards its closed position. A shackling member (15) is provided for holding the hooking arms (13) at their overlapping position even after the arms have been unlatched. The hair clip further has a restoring member (14) which urges the shackling member (15) to return to its another position where the arms are freed, when the hair retainer (4) is opened such that the engaging part (4b) can no longer be latched by the hooking arms (13). Such a mechanism makes easier the unlatching of the hair clip, which is simple in structure and easy to manufacture and assemble.

Abstract: Self-reinforced composites of amorphous thermoplastic materials such as poly(methylmethacrylate), polycarbonate and polysulfone are made by melt-extruding and simultaneously drawing and cooling the material to produce fibers with longitudinally-oriented molecular chains, then arranging the fibers in a preform, such as a mat, rod, plate or other useful shape, in which adjacent fibers are in contact with each other, and thereafter heating the preform with fiber constraint to a temperature above the glass transition temperature and below the degradation temperature of the thermoplastic, and applying pressure, to soften and fuse together the outer surfaces of the fibers without completely eliminating the longitudinal orientation of the molecules within the fibers. Where the amorphous thermoplastic is poly(methylmethacrylate), the preform may be wrapped about the bone-implantable element of a joint prosthesis to provide a high-strength integrated mantle of connected, contracted, and oriented fibers.

Abstract: An improved condylar platen an pad construction for use with most types of hinges used in orthopedica and orthotic appliances integrates, by moulding, a hinge back plate with a joint pad platen and shimming means. The platen has a flexible margin portion disposed about an extension molded peripheral to the enclosed hinge back plate. The flexible margin may be contoured for conformability to a joint. The extension creates a recess between the flexible margin and the hinge back plate. A joint pad is air and foam filled and a central portion of it fits within the recess of the platen and a peripheral portion locates on the flexible margin. The condylar pad is covered overall by a bonnet. The improved condylar platen construction eliminates drag between a platen and hinge arms and accelerates and eases manufacture by reducing and combining parts. The instant pad is more versatile and functionally effective than prior art pads.

Abstract: A film having at least two layers is disclosed, one layer being composed essentially of a water soluble/dispersible blend of polyethylene oxide (PEO) and plasticized polyvinyl chloride (PVC) and a second relatively weak layer being composed of a water insoluble polymer having high resistance to liquid and gas transmission, particularly a polymer or copolymer of vinylidene chloride (PVDC). Also disclosed is a collection pouch formed of such film. In the fabrication of such a pouch, the film panels are arranged with their PVDC layers in facing relation and the edges of such panels are then heat sealed to each other, resulting in a pouch of relatively high strength and resistance to delamination in use but capable of dissolving/dispersing quickly when discarded into the water of a flush toilet.
