Mindray Disinfectable Expiratory Valve Assembly 115-021461-00 115-015343-00

Introduction

The Mindray 115-021461-00 (and its related component 115-015343-00) is a sterilizable expiratory valve assembly, an original equipment manufacturer (OEM) component for Mindray ventilators. This assembly controls the flow rate of exhaled gases during mechanical ventilation.

The assembly includes a valve body, a medical-grade silicone diaphragm, and a seal. It is installed at the ventilator's expiratory port to control the release of exhaled gases to maintain the pressure and volume set by the clinician. This assembly is compatible with Mindray SV and E series ventilators.

Functions

1. Controls the flow of exhaled gas. The expiratory valve assembly is the active element that regulates the release of exhaled gases from the patient's breathing circuit. It ensures that the ventilator can accurately maintain the user-set pressure levels throughout the respiratory cycle.

2. Maintains stable PEEP. The medical-grade silicone diaphragm responds swiftly to pressure changes, ensuring stable Positive End Expiratory Pressure control. This is essential for keeping the alveoli open and improving oxygenation in critically ill patients.

3. Provides accurate flow and volume monitoring. The valve assembly supports expiratory flow and volume monitoring. This data is fed back to the ventilator's control system, enabling it to adjust therapy in real time and ensuring the patient receives the prescribed tidal volume.

Please note

• Ensure correct compatibility. The 115-021461-00 and 115-015343-00 assemblies are designed for use with Mindray SV300, SV350, SV600, SV800, E3, and E5 ventilators.
• Clean and disinfect before use. The manufacturer states that the valve must be cleaned and disinfected before use to avoid spreading infection or other accidents.
• Inspect the valve before each use. Visually check the valve body, the silicone diaphragm, and the rubber gasket for any signs of damage, cracks, or wear. Do not use a valve that appears damaged.
• Replace according to hospital policy. The replacement interval should be determined by your hospital's infection control procedures and the patient's condition.
• Perform a leak test after installation. Always perform the tightness test (leak test) as described in the ventilator's user manual before connecting the patient.
• Ensure an alternative ventilation source is available. Always make sure a backup ventilation method is ready before performing any maintenance or checks on the ventilator.
