Abstract
Disclosed are various embodiments for an anti-reflux enema bag having a pulley restrictor that acts as a waterflow restrictor, where the enema bag is leakproof, easy-to-clean, and provides a steady flow of solution. An enema bag system includes an enema bag, a nozzle comprising a nozzle outlet, and an anti-reflux coupler positioned between the enema bag and the nozzle through which the solution passes from the enema bag to the nozzle outlet. The anti-reflux coupler comprises an inlet for receiving at least a portion of the solution from the enema bag; an outlet for expelling the solution into the nozzle; and a check valve configured to prevent reflux of the solution from the nozzle. The enema bag system further comprises a pulley restrictor configured to selectively control a speed at which the solution is introduced into the nozzle and expelled from the nozzle outlet.
