Double syringe barrels with ported delivery ends

A syringe system for mixing first and second materials together and delivering the mixed materials, comprising:

• a dual barrel cartridge having a proximal grasping end opposite from a distal delivery end, the dual barrel cartridge including first and second barrels;
• each barrel having an opening at the proximal grasping end of the dual barrel cartridge and a barrel outlet at the distal delivery end of the dual barrel cartridge;
• the dual barrel cartridge having opposing claws at its distal delivery end;
• a dual lumen nipple having a receiving end opposite from a terminal end, the dual lumen nipple having cylindrical sidewalls extending integrally from the distal delivery end of the dual barrel cartridge;
• the dual lumen nipple having a first and a second lumen that are separate from each other and are respectively in fluid communication with the first and second barrels through the respective barrel outlets;
• the sidewalls being partially terminated such that each lumen has a side portal;
• each side portal having a bottom and sides that are defined by the sidewalls;
• a delivery tip having a proximal coupling end opposite from a distal delivery end;
• the delivery tip having a hub at its proximal coupling end that is integrally connected to a mixing element housing that houses a mixing element;
• the hub having sidewalls that define a delivery chamber and a delivery chamber opening;
• the mixing element housing defining a mixing chamber, a mixing chamber inlet that is opposite from the delivery chamber opening and a mixed material outlet opposite from the mixing chamber inlet;
• the delivery chamber being in fluid communication with the mixing chamber via the mixing chamber inlet;
• the delivery chamber being sized to releasably receive the nipple;
• the sidewalls of the hub having interior surfaces that include opposing raised sidewall portions between opposing sidewall channels;
• each opposing raised sidewall portions having sufficient width to form a seal with the sidewalls of the nipple once the nipple is inserted into the delivery chamber;
• each opposing sidewall channel being adapted such that when the nipple is inserted into the delivery chamber with each side portal opposite from each sidewall channel the material delivered out of each side portal is channeled to the mixing chamber inlet;
• and
• a removable collar adapted to hold the nipple in the receiving chamber once the tip has been inserted though an aperture of the removable collar and the collar locked under the claws of the dual barrel cartridge.

• a dual lumen nipple having a receiving end opposite from a terminal end;
• the dual lumen nipple having cylindrical sidewalls extending integrally from the distal delivery end of the dual barrel cartridge;
• the dual lumen nipple having a septum extending integrally from the distal delivery end of the dual barrel cartridge and across the sidewalls such that the dual lumen nipple has first and second lumens defined by the sidewalls and the septum;
• the first and second lumens are respectively in fluid communication with the first and second barrels through the respective barrel outlets;
• the sidewalls being partially terminated such that each lumen has a side portal;
• each side portal having a bottom and sides that are defined by the sidewalls;
• each side portal having a top defined by a flat sealing head that extends at the terminal end of the dual lumen nipple from the septum and a portion of the sidewalls;
• the flat sealing head having truncated flanges that extend perpendicularly relative to the septum;
• each truncated flange having a length that permits the material delivered out of each side portal to pass around the truncated flange when the nipple is inserted into the delivery chamber of the tip;
• a delivery tip having a proximal coupling end opposite from a distal delivery end;
• the delivery tip having a hub at its proximal coupling end that is integrally connected to a mixing element housing that houses a mixing element;
• the hub having hub sidewalls and a hub shoulder extending inward from the hub sidewalls to the mixing element housing, the hub having a delivery chamber defined by the hub sidewalls and the hub shoulder and having a delivery chamber opening defined by the hub sidewalls;
• the mixing element housing defining a mixing chamber, a mixing chamber inlet that is opposite from the delivery chamber opening and a mixed material outlet opposite from the mixing chamber inlet;
• the delivery chamber being in fluid communication with the mixing chamber via the mixing chamber inlet, the delivery chamber being sized to releasably receive the nipple;
• the hub sidewalls having interior surfaces that include opposing raised sidewall portions between opposing sidewall channels, the hub shoulder having interior surfaces that include opposing raised shoulder portions between opposing shoulder funnels;
• the opposing raised sidewall portions and the opposing raised shoulder portions being aligned and adapted to form a seal with the sidewalls and the flat sealing head of the nipple once the nipple is inserted into the delivery chamber, the opposing sidewall channels being aligned with the opposing shoulder funnels such that there is a separate pathway for each material from each side portal to the mixing chamber inlet;
• and
• a removable collar adapted to hold the nipple in the receiving chamber once the tip has been inserted though an aperture of the removable collar and the collar locked under the claws of the dual barrel cartridge.
