Publication number: 20230075627Abstract: A quick assembly and quick disassembly device for a faucet, configured for fastening of the faucet, comprises a base seat, an upper cover, and at least two locking blocks. The base seat comprises a mounting hole. The upper cover is sleeved outside of the faucet and is detachably connected to the base seat. Each of the at least two locking blocks comprises a first inclined surface pushed by at least two transmission members to enable the at least two locking blocks to move radially inward to abut the faucet. A position-providing notch between two adjacent locking blocks provides a space for a joint of a flexible hose so as to easily mount or detach the faucet. A distal end of the at least two elastic assemblies is disposed in at least two locking blocks to enable the at least two locking blocks to move outward to release the faucet.Type: ApplicationFiled: November 7, 2022Publication date: March 9, 2023Inventors: Jinfa WANG, Binghul Zhu, Xiangsheng Zheng

Patent number: 8620457Abstract: An implantable system for the defibrillation of the atria of a patient's heart comprises (a) a first catheter configured for insertion into the right atrium of the heart, preferably without extending into the right ventricle of the heart; a first atrial defibrillation electrode carried by the first catheter and positioned at the atrial septum of the heart (i.e., an atrial septum electrode); (b) a second atrial defibrillation electrode which together with the first atrial defibrillation electrode provides a pair of atrial defibrillation electrodes that are configured for orientation in or about the patient's heart to effect atrial defibrillation, and (c) a pulse generator operatively associated with the pair of atrial defibrillation electrodes for delivering a first atrial defibrillation pulse to the heart of the patient. The second electrode may be configured for positioning through the coronary sinus ostium and in the coronary sinus or a vein on the surface of the left ventricle, such as the great vein.Type: GrantFiled: January 17, 2006Date of Patent: December 31, 2013Assignee: UAB Research FoundationInventors: Xiangsheng Zheng, Michael E. Benser, Raymond E. Ideker, Gregory P. Walcott, Steven D. Girouard
