AIR FILTRATION SYSTEM WITH FILTER EFFICIENCY MANAGEMENT |
摘要 |
A filtration system for trapping airborne contaminants as exemplified i n evacuating smoke generated during a surgical procedure wherein operation efficiency thereof is automatically reported in relation to filter structure cumulative use time and cumulative airflow volume. In a first embodiment a system processor correlat es cumulative vacuum pump motor speed, operation duration, and air pressure difference measurements over an airflow filter path into a cumulative value and automatically compares that value to a plurality of known pre-determined correlated values to thereby provide filter life expectancy which is conveyed to a memory device of the filter structure for retention and conveyance for display. In a second embodiment a self- contained microprocessor and memory device of the filter structure is in communication with the system processor to receive, store, and send filter structure time-duration operability data which is sent to a data display site for display.
