Sealed Membrane Duckbill Valve Design

Sealed membrane duckbill valve design, achieving<1KPa pressure difference seal.

Integral design of sealing structure

Entire seal structure design for easy specimen or debris retrieval, effectively preventing sharp debris (such as needles) from piercing the duckbill valve.

Serrated design of outer casing

Thread cannula design for smooth puncturing, prevents pull-out and detachment, ensuring more secure abdominal wall fixation.

Beveled design of outer casing

The beveled design of the outer cannula reduces resistance when entering the abdominal cavity, allowing for more specimen capacity and easy to extract.
