Abstract

System for mixing four components including a first syringe arrangement and a second syringe arrangement each with two chambers for holding components. Each of the two respective chambers of the syringe arrangements are connected in a uniquely defined fashion due to specific means for connecting the syringe arrangements. A component held by one chamber is mixed with a component of the corresponding other chamber by transfer into the other chamber. After mixing and disconnecting the second syringe arrangement from the first syringe arrangement, the two component mixtures in the chambers of the first syringe arrangement are further mixed and discharged by means of a mixing device which is to be connected to the first syringe arrangement. The connecting means allows connecting of the mixing device to the first syringe arrangement only after removal of the second syringe arrangement and a portion of the connecting means.

Claims

1. System for mixing at least four components, the system comprising a first syringe arrangement and a second syringe arrangement, the first and the second syringe arrangements each containing at least two chambers for holding each one of the components, the first syringe arrangement having a connecting means for connecting the chambers of the first syringe arrangement in a detachable fashion to the chambers of the second syringe arrangement so that components which are contained in the chambers of the second syringe arrangement can be mixed with the components which are contained in the connected chambers of the first syringe arrangement by transferring said components into the connected chambers of the first syringe arrangement to form a mixture of two components in each chamber of the first syringe arrangement, wherein at least a portion of the connecting means is removable from the first syringe arrangement upon separating said first and second syringe arrangements after said mixing, so that a mixing device for further mixing by discharging of the mixtures from the chambers of the first syringe arrangement can only be connected to said first syringe arrangement after said mixing of the components and when the second syringe arrangement and the connecting means portion have been disconnected from the first syringe arrangement.

2. System according to claim 1, wherein the connecting means includes a coding sleeve, a coding disc or a coding element.

3. System according to claim 1, wherein the connecting means includes means for connecting the chambers of the one syringe arrangement to the chambers of the other syringe arrangement in a uniquely defined fashion.

7. System according to claim 1 or 4, wherein at least one syringe arrangement has syringes with syringe plungers which can be connected to one another.

4. System for mixing at least four components, the system comprising a first syringe arrangement and a second syringe arrangement, the first and the second syringe arrangements each containing at least two chambers for holding each one of the components, wherein the syringe arrangements have means for connecting to one another in a detachable and uniquely defined fashion so that each chamber of one of the syringe arrangements can only be connected to a predetermined chamber of the other syringe arrangement so that components which are contained in the chambers of one of the syringe arrangements can be mixed with the components which are contained in the connected chambers of the other syringe arrangement by transferring said components into the connected chambers of the other syringe arrangement.

5. System according to claim 4, wherein the system has a mixing device which can be connected to the chambers of one of the syringe arrangements so that the mixed components which are contained in the chambers can be mixed further with one another by being discharged from the chambers through the mixing device.

6. System according to claim 4, wherein the connecting means for connecting one syringe arrangement to the other syringe arrangement in a uniquely defined fashion comprises a cam, a recess, a coding sleeve, a coding disc, a coding element, and/or a connecting projection.
