KANGXIN MECHANICAL AIR-OXYGEN BLENDER
=============================================================
Product Introduction & Technical Overview
=============================================================

1. PRODUCT OVERVIEW

   ---

   The Kangxin Mechanical Air-Oxygen Blender is a pneumatically
   controlled, purely mechanical medical gas mixing device
   designed for precise oxygen concentration regulation in
   respiratory support and ECMO applications.

   Engineered with a rugged, maintenance-free structure, it
   requires no electrical power supply, making it inherently
   safe for use in operating rooms, ICUs, neonatal units, and
   emergency care settings.

2. KEY PERFORMANCE FEATURES

   ---

   2.1 Continuous Oxygen Concentration Adjustment

   ---

   Oxygen concentration is linearly and continuously
   adjustable from 21% to 100%, allowing precise titration
   to meet varying patient oxygenation requirements.

   2.2 Independent Control of Concentration and Flow

   ---

   Oxygen concentration and gas flow are controlled
   independently via separate adjustment mechanisms,
   ensuring that changes to one parameter do not affect
   the other, thereby enabling stable and predictable
   gas delivery.

   2.3 High-Precision Regulation

   ---

   The blender delivers an oxygen concentration accuracy
   of ±3% (V/V), ensuring reliable and consistent gas
   mixtures for critical care applications.

   2.4 Pneumatically Controlled, No Power Supply Required

   ---

   The device operates entirely on pneumatic principles
   using a purely mechanical structure. It does not
   require any electrical power source, eliminating the
   risk of electronic failure and ensuring continuous
   operation even during power outages.

   2.5 Lossless Flow Output

   ---

   The blender maintains full, uncompromised gas flow
   output regardless of concentration settings, ensuring
   that flow delivery remains stable across the entire
   adjustment range.

   2.6 Zero Reverse Flow Protection

   ---

   The built-in reverse flow prevention mechanism
   eliminates the risk of backflow, protecting both the
   patient and the gas supply system from contamination
   or pressure anomalies.

4. SAFETY & ALARM SYSTEMS

   ---

   4.1 Differential Pressure Alarm
   The blender is equipped with a pneumatic differential
   pressure alarm that activates when the pressure
   difference between gas supplies exceeds safe limits.

   4.2 Gas Supply Interruption Alarm
   An integrated alarm system provides immediate audible
   notification in the event of gas supply failure from
   either the oxygen or air source.

   4.3 Built-in Pneumatic Audible Alarm
   All alarms are pneumatically driven, requiring no
   electrical power. The audible alarm produces a buzzer-
   type sound with a sound pressure level of ≥57 dB(A),
   ensuring clear notification in clinical environments.

   4.4 Three-Level Alarm Protection
   The system provides comprehensive protection through
   differential pressure monitoring, gas interruption
   detection, and overpressure safeguarding.
