Publication number: 20190207130Abstract: The present disclosure relates to a flexible display device, including a flexible substrate. The substrate includes a first portion, a second portion and a bending portion connecting the first portion to the second portion, wherein the flexible substrate has a thickness T. A plurality of display pixels is located at a side of the first portion of the flexible substrate. A supporting layer is located at a side of the flexible substrate facing away from the plurality of display pixels and includes a first supporting layer corresponding to the first portion and a second supporting area corresponding to the second portion. A thickness of the first supporting layer is T1, a thickness of the second supporting layer is T2, and a width of the bending portion is W, wherein W ? ( 2 ? T + T ? ? 1 + T ? ? 2 ) ? ? 2 . Therefore, a narrow border is achieved, and the problem of interference during bending is alleviated.Type: ApplicationFiled: April 19, 2018Publication date: July 4, 2019Inventors: Yongxin HE, Dong CHANG, Donghua CHEN, Zhenying LI

Patent number: 8813744Abstract: An anesthetic vaporizer and a temperature compensation unit are disclosed. The temperature compensation unit, which cooperates with a vaporizing chamber having a bottom wall, includes a first device connected to the bottom wall of the vaporizing chamber for contacting with liquid anesthetic agent in the vaporizing chamber and changing in length according to temperature change of the liquid anesthetic agent, and a second device connected to the vaporizing chamber. A gas flow gap through which a gas flow passes is formed between the first and second devices. The gas flow gap becomes larger as temperature of the liquid anesthetic agent rises and smaller as the temperature of the liquid anesthetic agent drops.Type: GrantFiled: January 14, 2010Date of Patent: August 26, 2014Assignee: Shenzhen Mindray Bio-Medical Electronics Co., LtdInventors: Donghua Chen, Daoming Gong, Zhiwei Qiao

Patent number: 8448638Abstract: An anesthetic vaporizer is disclosed herein which comprises a fresh gas inlet, a mixed gas outlet, a first gas branch circuit, a second gas branch circuit and a vaporizing chamber. The vaporizing chamber has a reservoir for containing an anesthetic agent. The first gas branch circuit connects the fresh gas inlet and the mixed gas outlet. The second gas branch circuit comprises a first pneumatic circuit, a pressure compensation unit, a second pneumatic circuit, a wick unit and a third pneumatic circuit. The pressure compensation unit has a curved, continuous and sealed vent slot. The wick unit has an immersion portion which is directly contacted with the anesthetic agent in the reservoir. The fresh gas inlet, the first pneumatic circuit, the vent slot, the second pneumatic circuit, the wick unit, the third pneumatic circuit and the mixed gas outlet are sequentially connected with one another.Type: GrantFiled: September 25, 2009Date of Patent: May 28, 2013Assignee: Shenzhen Mindray Bio-Medical Electronics Co., Ltd.Inventors: Donghua Chen, Daoming Gong, Wei Wang
