It is designed especially for draining purulent blood and other phlegmatic seceretion on operation room and emergency room in hospital. Features The diaphragm type pump in the aspirator is large in capacity,efficient and needs no lubricating.The pump runs practically with minumum noise.The suction bottle provides automatic over-flow cut-off system preventing liquid from flowing back into the pump.It can be started and kept running at the maximum negative pressure.(≥0.09Mpa)The unit has an ideal volume of suction capacity.The vaccum pressure can be controlled optionally from -0.02 0.09 Mpa (-150 680 mmHg).Due to the reasonable arrangement and appropriate height it allows the operator to observe and examine from all directions.It is simple to operate and easy to carry.
