The sensor plaster (116) comprises at least one flexible carrier element (134) having at least one adhesive surface (138) which can be stuck onto a body surface. Furthermore, the sensor plaster (116) comprises at least one radiation source, more particularly a light source (142), wherein the radiation source is designed to irradiate the body surface with at least one interrogation light (162). Furthermore, the sensor plaster (116) comprises at least one detector (146) designed to detect at least one response light (176) incident from the direction of the body surface.Type: GrantFiled: September 16, 2016Date of Patent: September 8, 2020Assignee: MediBeacon Inc.Inventors: Norbert Gretz, Johannes Pill, Daniel Schock-Kusch, Thomas Walter, Jürgen Hesser, Maliha Sadick, Felix Eickemeyer, Jae Hyung Hwang, Christian Schildknecht, Soichi Watanabe, Wolfgang Wach, Thomas Rose

Patent number: 10758502Abstract: A transdermal topical anesthetic formulation, which can be used to ameliorate or inhibit pain, has been developed. In the preferred embodiment, the topical anesthetic is a local anesthetic such as lidocaine, most preferably lidocaine free-base in a gel, and the dosage of the local anesthetic is effective in the painful area or immediately adjacent areas, to ameliorate or eliminate the pain. High concentration of local anesthetic in solution in the carrier is used to drive rapid release and uptake of the drug. Relief is typically obtained for a period of several hours.Type: GrantFiled: December 8, 2017Date of Patent: September 1, 2020Assignee: Centrexion Therapeutics CorporationInventors: James N. Campbell, Arthur F. Michaelis

Hydrophilic and biologically safe polymer foam as well as preparation method and application thereof
Patent number: 10745511Abstract: The present invention provides a method for preparing hydrophilic polymer foam. The method comprises a step of providing an isocyanate functionalized prepolymer (A) and a step of foaming and curing the prepolymer (A). The prepolymer (A) is prepared by reacting diisocyanate (A1) and polyether polyol (A2), wherein the diisocyanate (A1) is selected from any one and a combination of 1,4-butyl diisocyanate (BDI), lysine diisocyanate (LDI) and 1,5-pentyl diisocyanate (PDI); the polyether polyol (A2) is a copolymer of ethylene oxide (EO) and propylene oxide (PO) and/or butylene oxide (BO); the ethylene oxide has a weight percentage of about 50%-100% in the polyether polyol, and has an OH functionality degree of 3-6, a hydroxyl value of about 21 mg KOH/g-168 mg KOH/g and a number-average molecular weight of about 1000 g/mol to about 8000 g/mol; and NCO content in the prepolymer (A) is 1%-10%.Type: GrantFiled: February 3, 2018Date of Patent: August 18, 2020Inventors: Jianli Zhang, Qing Zhou
