1) CONNECTION TO VENTURI PUMP
The silicone tube from the Venturi pump connects to this tube holder. The
disposable cassette tank connects at the other side of the tube holder.
2) VACUUM SIGNAL FILTER (369130000)
This is the vacuum sensor and amplifier/filter board for closed system
vacuum reading in the disposable cassette.
3) INTERLOCK SWITCHES
This is a group of two switches activated by the the lever 5 of fig. 2.
When the lever is pushed by the user, the peristaltic pump head is moved
backwards to allow I/A cassette removal. The cassette installation causes
lever rotation that actiates the forward movement of the peristaltic pump
head; this locks the I/A cassette in place.
