Fitting for dental syringe tip

A fitting for releasably connecting a syringe tip having a longitudinal axis to a dental syringe having a first port for supplying a first fluid to the syringe tip and a second port for supplying a second fluid to the syringe tip, the tip having a first passageway extending generally parallel to the longitudinal axis for transporting said first fluid to a patient's mouth and a second passageway extending generally parallel to the longitudinal axis for transporting said second fluid to the patient's mouth, the fitting comprising:

• a body having a connector for attaching the body to the dental syringe, a recess for receiving the syringe tip, a first passage extending through the body to the recess, and a second passage extending through the body to the recess for directing said second fluid from said second port of the dental syringe to said second passageway of the syringe tip;
• a quick release mechanism mounted in the recess for quickly connecting the syringe tip to the body and disconnecting the syringe tip from the body, the mechanism including a manually operable actuator moveable in a direction generally parallel to the longitudinal axis between an engaged position in which the quick release mechanism prevents the syringe tip from being removed from the recess and a disengaged position in which the quick release mechanism permits the syringe tip to be removed from the recess;
• and
• a tubular connector for extending through the first passage into the recess, the tubular connector being sized and shaped for sealingly engaging said first passageway of the syringe tip for transporting said first fluid from said first port of the dental syringe to the syringe tip, said tubular connector having a base with a diameter larger than the first passage in the body and adapted to be captured outside the recess in generally fixed position between the body and the dental syringe when the body is attached to the dental syringe so that the base is prevented from passing through the first passage into the recess, thereby holding the tubular connector in generally fixed position relative to the body.

A fitting for releasably connecting a syringe tip having a longitudinal axis to a dental syringe having a port for supplying a fluid to the syringe tip, the tip having a passageway extending along the longitudinal axis for transporting the fluid to a patient's mouth and further having a substantially constant outer diameter, the fitting comprising:

• a body having a connector for attaching the body to the dental syringe and a recess for receiving the syringe tip, the body further having a passage therein extending through the body to the recess;
• and
• a quick release mechanism mounted in the recess for quickly connecting the syringe tip to the body and disconnecting the syringe tip from the body, the mechanism including a manually operable actuator adapted to selectively grip the substantially constant outer diameter of the syringe tip to prevent the syringe tip from being removed from the recess;
• and
• a tubular connector for extending through the passage into the recess, the tubular connector being sized and shaped for sealingly engaging the passageway of the syringe tip for transporting the fluid from the port of the dental syringe to the syringe tip, said tubular connector having a base with a diameter larger than the passage in the body and adapted to be captured outside the recess in generally fixed position between the body and the dental syringe when the body is attached to the dental syringe so that the base is prevented from passing through the passage into the recess, thereby holding the tubular connector in generally fixed position relative to the body.

• a body having a connector for attaching the body to the dental syringe, a recess for receiving the syringe tip, a first passage extending through the body to the recess, and a second passage extending through the body to the recess for directing said second fluid from said second port of the dental syringe to said second passageway of the syringe tip, and a stop in the recess for limiting travel of the syringe tip into the recess;
• a quick release mechanism mounted in the recess for quickly connecting the syringe tip to the body and disconnecting the syringe tip from the body, the mechanism being adapted to permit the syringe tip to move away from the stop before gripping the tip sufficiently to prevent farther movement away from the stop;
• and
• a tubular connector for extending through the first passage into the recess, the tubular connector being sized and shaped for sealingly engaging said first passageway of the syringe tip when the syringe tip is spaced from the stop for transporting said first fluid from said first port of the dental syringe to the syringe tip, said tubular connector having a base with a diameter larger than the first passage in the body and adapted to be captured outside the recess in generally fixed position between the body and the dental syringe when the body is attached to the dental syringe so that the base is prevented from passing through the opening into the recess, thereby holding the tubular connector in generally fixed position relative to the body.
