Ergonomic suction syringe and methods of use

A method of establishing suction in a lumen of a medical device comprising:

• (a) reversibly attaching an ergonomic suction syringe to said medical device, said ergonomic suction syringe comprising a back end disposed toward an operator and a forward end disposed toward said medical device, said ergonomic suction syringe further comprising a cylinder and a piston, said cylinder further comprising at least an air-tight back chamber disposed toward said back end and a forward chamber disposed toward said forward end, and said piston comprising at least a piston head securely attached to a piston rod, said forward chamber and said back chamber being separated from each other by said piston head, said piston head comprising an air-tight seal between said forward chamber and said back chamber, said piston head occupying a cross-sectional area of an interior of said cylinder, said ergonomic suction syringe further comprising a means of transfer of said vacuum from said back chamber to said forward chamber, and said ergonomic suction syringe further comprising a means of transmission of said vacuum from said forward chamber to a medical device by means of an adapter tip;
• and
• (b) slidably moving said piston in a forward direction from a first position disposed toward said back end to a second position disposed toward said forward end to generate said vacuum in said back chamber, and
• (c) slidably moving said piston in a further forward direction until said means for vacuum transfer between said back chamber and said forward chamber is actuated, thereby allowing vacuum to be transmitted to said forward chamber and by extension to said attached medical device.
