Syringe with controllable breaking features

A hand-held aspiration syringe configured for one-handed operation, comprising:

• a plunger having
• a seal at a forward end thereof,
• a push button at a rear end thereof,
• an internal plunger arm attached at a rear end thereof to the push button and to the seal at a forward end thereof,
• an external plunger arm attached at a rear end thereof to the push button and to a front plunger handle at a forward end thereof, the internal plunger arm being arranged adjacent to the external plunger arm, and
• wherein the front plunger handle extends radially away from the external plunger arm and having two portions separated from each other to each receive a different forefinger of a user,
• a barrel having
• a wall with an inner diameter that defines a hollow syringe cavity matches an outer diameter of the seal,
• a nozzle formed at a forward end of the barrel through which a fluid is drawn into an inner portion of the barrel in response to the seal being drawn away from the nozzle, and
• a barrel flange formed at a rear end of a hollow cylinder body of the barrel wherein at least one of the nozzle, the plunger, the barrel at a front portion thereof, and the barrel flange, and the internal plunger arm include a breaking point, the breaking point have a weaker mechanical integrity than surrounding material that breaks in response to an external force of a predetermined amount, wherein
• the barrel flange comprises polypropylene having a predetermined thickness, the breaking point includes a breaking point at the barrel flange that extends from one side of the barrel flange to the other side of the barrel flange and the breaking point of the barrel flange being less thick than the predetermined thickness of the barrel flange.
