MINOR ADDITIONS OF POLYVINYL PYRROLIDONE AND MELAMINE-FORMALDEHYDE RESINS TO PLASTER OF PARIS BANDAGES PERMIT MAKING "CASTS" OF IMPROVED STRENGTH AND WATERRESISTANCE WITH GOOD PHYSIOLOGICAL PROPERTIES.
摘要:
Disclosed herein are antimicrobial elastic support bandages including a plurality of warp threads extending along at least a portion of the length thereof and including non-antimicrobial warp regions and antimicrobial warp regions arranged in an alternating fashion across the width thereof, wherein (a) a non-antimicrobial warp region comprises an elastic material that is stretchable in the direction of the length, (b) an antimicrobial warp region comprises (i) a flexible fiber coupled to an antimicrobial metal, and (ii) an elastic material that is stretchable in the direction of the length, wherein the flexible fiber is coupled to the elastic material, and (c) at least a portion of the warp threads are separated by about 3 microns to about 20 microns; and further including a plurality of weft threads extending across at least a portion of the width and comprising a biocompatible material, wherein at least some of the weft threads are separated by about 3 microns to about 20 microns, wherein at least a portion of the warp threads are interwoven with at least a portion of the weft threads.
摘要:
A glass, glass-ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded by an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels, and nerves.
摘要:
A copper metal alloy, for use in making elements for promoting and/or stimulating vital energy comprises between 60% and 70% in weight of copper (Cu), between 16% and 24% in weight of silver (Ag), between 3% and 6% in weight of zinc (Zn), between 3% and 6% in weight of manganese (Mn) and between 0.5%> and 6%> in weight of germanium (Ge). Tin (Sn) in percentage comprised between 3% and 6% can also be provided for. Platinum (Pt) can also be provided for between 0.1% and 5% in weight. The alloy is used for making for example sheets in form of plates or strips which are associated to articles of various types.
摘要:
An Orthopaedic Plaster of Paris bandage (10) comprising a water resistant layer of material (50; 60) on at least one face of the bandage (10) which allows the bandage (10) to be cured by water but once the bandage (10) is set, the bandage (10) is water resistant against disintegration.
摘要:
An ecologically harmless process for the production of stiffening materials containing hydraulic binders, for example plaster bandages, is characterized in that a hydraulic binder is mixed in pulverulent form with a reactive binder, this mixture is applied to a sheet-like material, the sheet-like material thus coated is rolled up and the setting reaction of the reactive binder is allowed to proceed before, during and/or after the rolling-up.
摘要:
A composition which is particularly useful in semi-rigid medical supporting bandages comprising10 to 35% zinc oxide2 to 15% cellulose ether10 to 35% glycerin30 to 75% water.The composition is coated onto at least one side of a suitable substrate to form the bandage and is irradiated in order to preserve sterility. Preferably, the radiation would take place after the bandages have been packaged.
摘要:
A method of improving the wet-strength characteristics of a plaster of Paris cast is disclosed. The cast bandage is immersed in dip water which contains 2%-15% by weight of a fluorochemical or the fluorochemical is applied to the finished cast. The fluorochemical is dispersed in the water by a nonionic or cationic surfactant. The resulting cast has improved water-resistant properties.
