Abstract:
1. An intravenous fluid administration apparatus comprising: a proximal conduit having: a distal conduit; an intermediate conduit network providing fluid communication from the proximal conduit's second end to the distal conduit and including first and second constituent conduits that provide parallel paths from the proximal conduit to the distal conduit; a flow regulator so engaged with the first constituent conduit as to enable control of fluid flow therethrough; and a pressure-responsive valve so interposed in the second constituent conduit as to permit flow from the proximal conduit to the distal conduit through the second constituent conduit when a fluid pressure difference across the valve exceeds a threshold and to prevent flow from the proximal conduit to the distal conduit through the second constituent conduit when the fluid pressure difference across the valve does not exceed the threshold.
