1. A system comprising:
a hose-end adapter comprising:
a main body that defines an outside annular surface, a proximal side, a distal side, and a central axis;a counter bore within the main body along the central axis, the counter bore defines an inside diameter and an end wall;a plurality of hose nipples on the distal side of the main body; anda plurality of fluid passages through the end wall of the counter bore, the fluid passages extend one each through a hose nipple of the plurality of hose nipples; a plurality of hoses, each hose defines a proximal end, a distal end, a length, and internal flow lumen, the proximal end of each hose telescoped over hose nipple of the plurality of hose nipples; a plurality of balloon nipples coupled one each to the distal ends of plurality of hoses, each balloon nipple comprising:
a connector on a proximal end of balloon nipple, the connector coupled to a respective hose of the plurality of hoses;a frustum region distal to the connector, the frustum region defines a conic frustum with a narrow portion disposed proximate to the connector, and a wide portion distal to narrow portion;a tubular region distal to the frustum region, the tubular region having an outside diameter smaller than the wide portion of the frustum region, the tubular region defines a constant outside diameter over at least a portion of a length of the tubular region; anda fluid passage defined at least in part along a central axis of the balloon nipple, at least a portion of the fluid passage defines a cross-sectional area configured to regulate flow of liquid through the fluid passage. |
