4. ETR Medical Central Vacuum SystemWorking Principle

The ETR Medical Central Vacuum System is a centralized, high-efficiency suction system designed for hospitals and healthcare facilities. It provides continuous and reliable vacuum pressure for medical suction applications across multiple patient care areas, including operating rooms, ICUs, emergency rooms, and general wards.

1. System Overview

The system consists of a central vacuum pump station, vacuum reservoir tank, solenoid valves, piping network, control system, and terminal suction outlets installed at patient bedsides or treatment stations.

2. Working Principle (Step-by-Step)

Step 1: Vacuum Generation
The heart of the system is the oil-lubricated or dry-running vacuum pump unit, which creates and maintains a continuous vacuum. The pump draws air from the system and discharges it to the atmosphere, creating negative pressure (sub-atmospheric pressure).

Step 2: Vacuum Storage
A vacuum reservoir tank stores the generated vacuum, acting as a buffer to stabilize pressure fluctuations and provide suction power even during pump cycling or maintenance.

Step 3: Control and Monitoring
An intelligent electrical control system monitors the vacuum level in real-time. It automatically starts or stops the vacuum pumps based on the preset pressure thresholds (e.g., between -0.06 MPa to -0.09 MPa), ensuring energy efficiency and system longevity.

Step 4: Distribution Through Piping Network
The vacuum is distributed throughout the hospital via a dedicated stainless steel or copper piping network, which connects the central pump station to all suction outlets in various departments.

Step 5: Suction at Terminal Outlets
When a medical professional activates the suction device at a terminal vacuum outlet, the negative pressure from the system draws bodily fluids or secretions from the patient through the connected tubing into a collection canister.

Step 6: Safety and Redundancy
The system includes:

• Multiple vacuum pumps (with one as a backup)
• Vacuum solenoid valves for isolation and protection
• Alarm systems for low vacuum, power failure, or pump failure This ensures continuous operation and patient safety, even during maintenance or equipment failure.
