Patent number: 10537727Abstract: A fluid connection system and a method of attaching the same are provided to create a sterile fluid-flow path. The connection system includes a fluid access device having a female connector with a female elastomeric member disposed at a proximal end thereof and is coupled to an internal surface of the fluid access device. A male connector is coupled to an external surface of the female elastomeric member. Additionally, a male elastomeric member is disposed within the distal end of the male connector and seals a distal opening thereof. At least one aperture is disposed through a sidewall of the distal end of the male connector. An internal cannula is exposed out of the female connector to open the female elastomeric member upon engagement with the male connector. The male connector is sealed to the female connector by the male elastomeric member.Type: GrantFiled: September 21, 2017Date of Patent: January 21, 2020Assignee: Avasys, LLCInventor: Cameron C. Jones

Patent number: 10502350Abstract: A quick water intake device comprises a tubular main body. The main body has a channel, and a first seal core, and an elastic piece. Under the action of the elastic piece, the first seal core can block the channel. A second seal core is also slidably arranged inside the main body. The second seal core is located between the first seal core and an outlet end of the main body, and when subjected to forces, the second seal core can move toward the first seal core and drives the first seal core to compress the elastic piece. A sealing structure arranged between an outer wall of the second seal core and an inner wall of the main body can form a seal between an outer wall of the second seal core and the main body to block the channel when the second seal core moves toward the outlet end.Type: GrantFiled: December 4, 2017Date of Patent: December 10, 2019Assignee: Yuhuan Haolixin Copper Co., Ltd.Inventor: Daoze Xu
