The MODUflex Bain circuit adaptor, 

unparalleled quality and ergonomics.

A Bain type open circuit on an anesthesia machine gives you better control during surgery. The breathing bag is always inflated, no need to wait for it to have reached a certain size before ventilating the patient. Compared to other open circuits, such as the Jackson Rees and the Ayres T Piece, the Moduflex Bain is equipped with a pressure gauge that gives you the possibility to check the animal's lung pressure. The Bain adaptor is equipped with a brass, momentary off pop off valve to avoid forgetting the valve in a closed position, which could cause pulmonary trauma to the animal.

  • Integrated gas evacuation valve is a one quarter turn valve designed for a rapid transfer between spontaneous and controlled ventilation
  • Integrated gas evacuation exhaust port is built into the mounting bracket, eliminating the risk of obstruction in the tube
  • Integrated 0.5 cm H2O check valve built into the adaptor to reduce the possibility of a faulty evacuation system drawing out into the patient's fresh gas supply
  • A pressure gauge offers excellent visibility of circuit pressure
  • 5 year warranty
