Abstract
Disclosed are devices, systems and methods for reducing noise from surgical and dental suction tips, especially Frazier and Fukushima type cannulas, by altering the size, shape, and contour of control valves. More specifically, the disclosed devices modify sound generated by traditional suction tips and/or thumbhole controls of various suction cannulas, (also called control valves, control vents, grip plates, and/or suction interrupters) by decreasing the intensity of the sound output of the suction cannula's amplitude and changing the frequency to a less annoying pitch.
Claims11
A suction device for an aspirator connectable to a vacuum source, comprising:
- a body having a first end having an inlet port, a second end having an outlet port, and a primary lumen extending through the body from the inlet port to the outlet port;
- an air chamber positioned within the primary lumen;
- and
- a control opening laterally spaced from the primary lumen, the control opening in fluid communication with the air chamber through a secondary lumen;
- the primary lumen having a first diameter proximate to the inlet port and a second diameter proximate to the air chamber, the first diameter being larger than the second diameter.
