The passive AGSS pneumatic block assembly consists of three parts: adapter block assembly,
waste gas scavenging pipeline, and ACGO waste gas inlet. The adapter block assembly connects
the gas reservoir to the atmospheric pipeline and integrates the ACGO waste gas inlet pipeline.
The waste gas scavenging pipeline is connected to the atmospheric pipeline.

2.3.8 Negative Pressure Suction Subsystem
The negative pressure suction subsystem controls negative pressure and delivers negative
pressure to the patient side. The continuous negative pressure suction subsystem is directly
connected to an external negative pressure source (the external pressure is negative pressure)
through the negative pressure inlet assembly, and provides only the negative pressure (flow)
regulating function.
