Abstract
A surgical evacuation system having dual in-series large and small droplet filters is provided. The surgical evacuation system comprises a pump, a motor operably coupled to the pump, and a flow path fluidically coupled to the pump. the flow path comprises a first fluid filter configured to extract a large droplet in a fluid moving through the flow path and a second fluid filter configured to extract a small droplet in the fluid moving through the flow path. the first fluid filter is coupled in series with the second fluid filter. The first fluid filter is positioned upstream of the second fluid filter. An outlet port of the second fluid filter is coupled to an inlet port of a non-fluid filter.

A surgical evacuation system, comprising:
- a pump;
- a motor operably coupled to the pump;
- and
- a flow path fluidically coupled to the pump, wherein the flow path comprises:
- a first fluid filter configured to extract a large droplet in a fluid moving through the flow path;
- and
- a second fluid filter configured to extract a small droplet in the fluid moving through the flow path, wherein the second fluid filter is different than the first fluid filter, wherein the first fluid filter is coupled in series with the second fluid filter, wherein the first fluid filter is positioned upstream of the second fluid filter, and wherein an outlet port of the second fluid filter is coupled to an inlet port of a non-fluid filter.
A surgical evacuation system, comprising:
- a pump;
- a motor operably coupled to the pump;
- and
- a flow path fluidically coupled to the pump, wherein the flow path comprises:
- a first fluid filter configured to extract a large droplet in a fluid moving through the flow path, wherein the first fluid filter comprises at least one baffle;
- and
- a second fluid filter configured to extract a small droplet in the fluid moving through the flow path, wherein the second fluid filter is different than the first fluid filter, wherein the second fluid filter comprises a filter selected from the group consisting of a membrane filter, a honeycomb filter, a porous structure filter, and combinations thereof, wherein the first fluid filter is coupled in series with the second fluid filter, wherein the first fluid filter is positioned upstream of the second fluid filter, and wherein an outlet port of the second fluid filter is coupled to an inlet port of a non-fluid filter.
