Claims22
A coupling syringe system for obtaining a mixed composition comprising a first syringe having a male end portion and a second syringe having a female end portion, wherein the male end portion comprises a locking ring configured to detachably connect to the female end portion of the second syringe.
A syringe having a female end portion wherein the female end portion is configured to detachably connect to a male end portion of a second syringe via a locking ring of the second syringe.
A method for forming a mixed composition wherein a first syringe containing a first composition is directly detachably connected to a second syringe containing a second composition comprising forcing at least a portion of the first composition into the second syringe or forcing at least a portion of the second composition into the first syringe thereby providing a mixed composition.
A method for administering a mixed composition to a patient wherein a first composition is contained within a first syringe, a second composition is contained within a second syringe, and the first syringe is detachably connected to the second syringe via a locking ring, comprising:
- forcing at least a portion of the first composition into the second syringe or forcing at least a portion of the second composition into the first syringe, effective to provide a mixed composition;
- disconnecting the first and second syringes;
- connecting the locking ring of the first syringe to a discharge assembly configured to detachably connect to the locking ring;
- inserting a portion of the discharge assembly into the patient;
- and
- forcing at least a portion of the mixed composition through the discharge assembly effective to administer the portion of the mixed composition to the patient.
