PASSIVE RESTART Y-SITE

摘要

A fluid delivery Y-site is described that is configured to receive and control delivery of two or more fluid flows. Fluid flow is controlled within a chamber by a valve and float. Flow of a primary fluid into the chamber is reduced or halted by the movement of a valve. The valve may occlude a first flow port into the chamber in response fluid flowing from a second flow port into the chamber. A float is moveably disposed within the chamber and configured to engage the valve in response a fluid flow into the chamber from the second flow port. As fluid flow from the second flow port into the chamber is reduced or ceases, the valve and float allow the flow from the primary flow port to once again enter the chamber and exit from an outlet port.

主权项

1. A fluid delivery Y-site device comprising:
a chamber fluidly coupled between a primary flow port and an exit flow port; a secondary flow port fluidly coupled to the chamber, the secondary flow port configured to conduct fluid to the chamber; and a valve positioned adjacent the primary flow port, the valve configured to move between an occluding configuration and an open configuration, based on a level of fluid within the chamber, such that the valve controls fluid flow through the primary flow port and into the chamber.
