Abstract

The present invention shows and describes a surgical suction device using positive pressure gas. The surgical suction device includes an air amplifier. The air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. The cylindrical cavity is defined by inner walls of the cavity. The air amplifier includes an annular opening in the inner wall near the first end. The annular opening defines an injection opening adapted to allow pressurized gas to flow out of the annular opening such that a region of low pressure is created at the first end and an amplified flow is created at the second end. The annular opening is also configured such that pressurized gas enters the cavity at an angle relative to the inner wall of the cavity towards the second end.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Application No. 62 / 191,689, filed July 13, 2015, which is incorporated herein by reference. Background technique [0003] Suction may be generated in a variety of ways in many different applications. In general, suction generating devices are used to remove gases, liquids, or any combination thereof from the environment. Suction is typically generated by electric or motor-driven devices, which tend to be noisy and bulky. Contents of the invention [0004] Described herein are devices, systems, and methods for providing suction. In one embodiment, the suction is generated passively. [0005] Described herein is a surgical suction device that includes an air amplifier. In one embodiment, an air amplifier includes a structure defining a generally cylindrical cavity having a first opening at a first end and a second opening at a second end. In one embodiment, the cylindrical cavity is defi...
