Medical Adjustable Venturi Oxygen Mask with 6 Color-Coded Diluters and Kink-Resistant Flex Tube for Precision FiO2 Control

Product Overview

The Venturi Oxygen Mask, also known as a constant-concentration mask, is a professional respiratory consumable designed for patients requiring precise control of fraction of inspired oxygen (FiO2). Crafted from high-transparency medical-grade PVC, this product’s core feature is the set of six color-coded Venturi valves. Utilizing the "Venturi Effect," it ensures that oxygen and ambient air are mixed in a fixed ratio, providing a stable and adjustable total gas flow to the patient.

Primary Intended Use

The Venturi mask is primarily used in Emergency Departments, Respiratory Wards, and ICUs. Because it delivers constant and accurate oxygen concentrations (ranging from 24% to 50%), it is considered the "Gold Standard" for patients with Chronic Obstructive Pulmonary Disease (COPD) and chronic respiratory failure, effectively preventing respiratory depression caused by excessive oxygenation.

Key Advantages

1. Precision Oxygen Control: Each color corresponds to a specific FiO2 level (Blue 24%, Yellow 28%, White 31%, Pink 40%, Orange 50%, etc.), allowing clinicians to switch concentrations rapidly without complex calculations.

2. Stable Gas Flow: Equipped with a 15cm flexible corrugated tube (Flex Tube) that acts as a reservoir and prevents airflow interruption caused by tube kinking during patient movement.

3. High Reliability: Even if the input oxygen flow fluctuates, the total gas flow delivered into the mask remains stable due to the Venturi valve design.

4. Ergonomic Comfort: The flexible PVC mask features an anatomical design with an adjustable nose clip and high-elasticity strap, ensuring a secure seal while minimizing skin irritation.

5. Humidification Support: Includes a large transparent humidification hood that connects directly to humidification devices, preventing patient airway dryness.

Frequently Asked Questions (FAQ)

Q: Why are there so many colors for the Venturi valves?

A: The color codes follow international standards for quick identification. Each color has a specific orifice size that determines the air entrainment ratio. This allows healthcare staff to verify oxygen concentration by color alone, reducing errors in high-pressure environments.

Q: What is the purpose of the corrugated "Flex Tube"?

A: The flex tube connects the colored diluter to the mask. it acts as a small reservoir to ensure that the patient receives the preset constant concentration even during high peak inspiratory flows, while also providing flexibility for patient movement.

Q: Is the product DEHP-free or Latex-free?

A: Our masks are manufactured from 100% medical-grade PVC. We can provide DEHP-Free or Latex-Free versions upon request to ensure no allergic reactions occur during treatment.
