  • Patent number: 6558709
    Abstract: A method for controlling the formation of a hydroxyapatite bone filler from dry calcium phosphate precursors in an aqueous solution uses coated sodium phosphate powder. The sodium phosphate powder is coated with a water soluble cellulose. Until the cellulose dissolves in the aqueous solution setting of the calcium phosphate cements proceeds slowly but when the exposed sodium phosphate particles start to solubilize in the aqueous solution the setting rate increases.

  • Patent number: 6521265
    Abstract: A method of arresting the flow of blood and other protein containing body fluids flowing from an open wound and for promoting wound healing. In the method, a substantially anhydrous compound of a salt ferrate is provided for a unique use which, when hydrated after mixing with a victim's own blood or other aqueous media, produces Fe+++ thereby promoting clotting when applied in a paste form to the wound for a time sufficient to arrest substantial further blood and other body fluid flow from the wound. The compound is formed of a ferrate (VI) salt taken from the group consisting of H, Li, Na, K, Rb, Cs and Fr. However, to decrease or eliminate stinging sensation, the compound may be formed having a ferrate (VI) salt taken from the group consisting of Be, Mg, Ca, Sr, Ba, Ra, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, In, Sn, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, TI, Pb, Bi, Al, As, NH4 and N(C4H9)4.

  • Patent number: 6515029
    Abstract: An absorbent article having a bodyside liner includes a hydrophilic lotion formulation on the outer bodyfacing surface thereof. The hydrophilic lotion formulation comprises from about 10 to about 90 weight percent of a hydrophilic solvent, from about 5 to about 90 weight percent of a high molecular weight polyethylene glycol, and from about 0 to about 60 weight percent of a fatty alcohol. The hydrophilic lotion formulation has a reduced adverse effect on the absorbent and liquid uptake properties of the liner and the absorbent body when compared to conventional lipophilic or hydrophobic lotion formulations. The hydrophilic lotion formulation acts as a lubricant to reduce the abrasion of the skin caused by the liner and also transfers to the skin to provide improved skin health.
