Publication number: 20230270657Abstract: The present invention contemplates a topical ophthalmic system for treating a Gram-positive bacterially-infected mammalian eye. The system comprises an ophthalmic composition containing a halogenated fluorescein or a pharmaceutically acceptable salt or ester thereof dissolved or dispersed in an aqueous ophthalmic carrier and present in an anti-bacterial keratitis-treating effective concentration of about 0.2 µg/mL to about 50 µg/mL. The ophthalmic composition has a pH value of about 6.5 to about 7.6, a viscosity of about 10 to about 300 cps and an osmolality of about 270 mOsm/kg to about 340 mOsm/kg. The ophthalmic composition is present in a vessel opaque to actinic light. Also contemplated is a method of treating a mammal having a Gram-positive bacterial infection of an eye by administering the ophthalmic composition to the infected eye and maintaining the treated eye in the substantial absence of actinic light for about 3 hours to about 12 hours.Type: ApplicationFiled: December 27, 2022Publication date: August 31, 2023Applicants: Provectus Pharmatech, Inc., University of Tennessee Research FoundationInventors: Michio Kurosu, Dominic Rodrigues, Edward V.

Publication number: 20230233515Abstract: This invention contemplates combined use of a rose bengal (RB) derivative with irradiation of bacteria with light to treat and kill the irradiated bacteria. In one aspect, Gram-positive bacteria are treated in a method in which the bacteria are contacted with an aqueous pharmaceutical composition containing a rose bengal (RB) compound of Formula I, discussed within, dissolved or dispersed therein at about 0.2 to about 3.1 µg/mL. Those contacted bacteria are contacted with light of the wavelength about 500 nm to about 600 nm for a time period of about 1 to about 10 minutes to provide a light dose of about 0.7 to about 7.2 J/cm2. A similar method is contemplated for treating Gram-negative bacteria that are one or more of Burkholderia, Salmonella, and Proteus using an aqueous pharmaceutical composition containing about 2 to about 15 µM concentration of the RB compound.Type: ApplicationFiled: December 27, 2022Publication date: July 27, 2023Applicants: Provectus Pharmatech, Inc., University of Tennessee Research FoundationInventors: Michio KUROSU, Dominic RODRIGUES, Edward V.

Patent number: 5774914Abstract: A hospital bed (10) especially adapted for use by a woman giving birth is disclosed. The bed includes a base (11) on which a litter frame (12) is positioned. A lift assembly (14) attached to the base and is connected to a inner frame (50) located inside the litter frame. The lift assembly moves the inner frame and litter frame up and down. The litter frame is pivotally connected to the inner frame so that the litter frame can be selectively moved in the Trendelenburg position. A Fowler frame (16) is attached to the litter frame so that it can be both pivoted upwardly from the horizontal and selectively moved toward the seat end of the litter frame. Foot rests (30) are attached to the under surface of the litter frame and can be swung into position as needed. Leg rests (34) are mounted to the under surface of the foot rests and likewise be simply pivoted in place. A foot frame (24) is attached to the seat end of the litter frame and can be readily separated from the rest of the bed.Type: GrantFiled: January 5, 1996Date of Patent: July 7, 1998Assignee: Stryker CorporationInventors: Ned Johnson, John Luecke, John Lacey
