Publication number: 20240082160Abstract: An amlodipine dry suspension, comprising a diluent, a suspending aid, etc. and being free of surfactants. A preparation method therefor comprises the following steps: a) preparing an aqueous mixture 1 containing amlodipine besylate by using a high-speed homogenization method; b) adding sodium benzoate to the mixture 1, and homogenizing same at a high speed to obtain a mixture 2; and c) granulating the mixture 2 and other components, and then drying same. The raw materials are homogenized and mixed at a high speed, no surfactant is added during the preparation, amlodipine is fully wetted by using a high-speed homogenization process, prescription components are simplified, and the amlodipine dry suspension is more suitable for children to use. Compared with ultrasonic stirring, scaled-up and industrial production are easier to realize for the high-speed homogenization process, and at the same time, the preparation is good in stability and convenient to carry.Type: ApplicationFiled: December 31, 2021Publication date: March 14, 2024Inventors: Hanxiong Li, Xianzhu Wang, Weitang Chen, Yuan Chen, Ping Guo, Yongyi Wu, Yongmei Qin, Hongxue Huang, Li Wang

Patent number: 10709261Abstract: An improved baby carrier is disclosed that includes a support frame coupled to a seating assembly though a suspension mechanism to provide weight support for a baby or toddler. The baby carrier includes an attachment harness worn by an adult to provide non-slip coupling between the baby carrier and the adult. The baby carrier also includes a semi-rigid coupling between the seat and harness assembly, a seat height adjustment capability, a sturdy support frame configuration, and a braking system. The baby carrier is a structurally stable device, and during use, significantly reduces the load of carrying the baby or toddler on the adult. Further, the baby carrier can have a compact size in a “stowed mode” for mobility, and can be used to meet a variety of user needs and carrying scenarios.Type: GrantFiled: January 24, 2018Date of Patent: July 14, 2020Assignee: BridgeHub LLCInventors: Yongmei Wang, Xinlin Ye, Ting Wang, Jianyong Zhou
