1. A medical infusion pump for sequentially injecting solutions from multiple syringes comprising:
a housing having a first cradle and a second cradle, each cradle being configured to receive a syringe; a first set of one or more cylinders positioned along the first cradle, each of the one or more cylinders in the first set having a piston and a piston rod that is connected to a first bridge, the first bridge being configured to contact a plunger of a first syringe when the first syringe is positioned within the first cradle such that, as the one or more pistons in the first set of cylinders are actuated, the first bridge applies a force to a plunger of the first syringe; and a second set of one or more cylinders positioned along the second cradle, each of the one or more cylinders in the second set having a piston and piston rod that is connected to a second bridge, the second bridge being configured to contact a plunger of a second syringe when the second syringe is positioned within the second cradle such that, as the one or more pistons in the second set of cylinders are actuated, the second bridge applies a force to a plunger of the second syringe; wherein a size of the one or more pistons in the first set of cylinders is greater than a size of the one or more pistons in the second set of cylinders such that when a pressure is applied to each piston in the first and second sets, the force applied by the first bridge to the plunger of the first syringe is greater than the force applied by the second bridge to the plunger of the second syringe thereby causing a first solution that exits the first syringe to have a greater pressure than a second solution that exits the second syringe. |
