Engineered in Class 10,000 cleanrooms to comply with European Medical Device Regulation (EU MDR) and Bulgarian Ministry of Health standards.
In high-acuity respiratory care, maintaining exact Fraction of Inspired Oxygen (FiO2) is vital for patients suffering from Chronic Obstructive Pulmonary Disease (COPD), acute hypercapnic respiratory failure, and acute respiratory distress syndrome (ARDS). Unlike standard simple face masks or non-rebreather systems—where oxygen delivery fluctuates drastically based on the patient's peak inspiratory flow rate—the Venturi Mask (Air-Entrainment Mask) utilizes the foundational physics of the Bernoulli Principle to deliver fixed, precise concentrations of oxygen regardless of respiratory pattern.
As a leading global exporter of single-use medical devices, our enterprise manufactures high-precision Venturi masks engineered with calibrated entrainment diluters. High-velocity oxygen flowing through a restricted jet orifice creates a localized low-pressure zone. This pressure differential draws room air through adjustable ambient ports at a mathematically constant ratio, generating a total gas flow that exceeds the patient’s peak inspiratory demand. This mechanism effectively eliminates room air dilution during inhalation and prevents carbon dioxide rebreathing during exhalation.
Information Gain Insight: Our Venturi Mask color-coded diluter system is calibrated under ISO 13485 cleanroom protocols to ensure a strict variance margin of less than ±1% FiO2 across oxygen input rates from 2 to 15 Liters Per Minute (L/min). This guarantees reliable blood gas stability in intensive care and sub-acute pulmonary units.
Bulgarian medical procurement officers and clinical engineering departments require exact gas dynamics data for hospital inventory standardisation. Below is the operational calibration matrix for our fixed color-coded Venturi valve assemblies:
| Diluter Color Code | Target FiO2 Concentration (%) | Required O2 Input Flow (L/min) | Air-to-Oxygen Entrainment Ratio | Total Delivered Gas Flow Rate (L/min) | Primary Clinical Indication |
|---|---|---|---|---|---|
| Blue | 24% | 2 L/min | 25 : 1 | 52 L/min | Severe COPD with Retained CO2 Risk |
| Yellow | 28% | 4 L/min | 10 : 1 | 44 L/min | Mild to Moderate Hypoxemia |
| White | 31% | 6 L/min | 7 : 1 | 48 L/min | Controlled Post-Operative Recovery |
| Green | 35% | 8 L/min | 5.6 : 1 | 52.8 L/min | Acute Exacerbation of Asthma / COPD |
| Pink | 40% | 10 L/min | 3 : 1 | 40 L/min | Moderate Respiratory Distress |
| Orange | 50% | 15 L/min | 1.7 : 1 | 40.5 L/min | Severe Refractory Hypoxemia |
Bulgaria’s healthcare system is undergoing structural modernisations driven by European Union infrastructure funds, state-backed hospital upgrades, and increased procurement transparency within the National Health Insurance Fund (NHIF / Национална здравноосигурителна каса - НЗОК). Major hospital centers in Sofia, Plovdiv, Varna, Burgas, and Pleven are rapidly standardising their single-use respiratory and urological inventories to meet strict EU Medical Device Regulation (EU MDR 2017/745) requirements.
Bulgarian medical device importers, tenders, and wholesale distributors face unique challenges, including strict price ceilings set by public tender framework agreements, rigorous biological safety audits by the Bulgarian Drug Agency (BDA / Изпълнителна агенция по лекарствата), and the demand for continuous, uninterrupted supply chains across Eastern Europe.
All Venturi masks, oxygen delivery systems, and silicone Foley catheters exported to Bulgaria must feature valid CE certifications, complete technical documentation files (TDF), and validated Ethylene Oxide (ETO) residual reports below EN ISO 10993-7 thresholds.
Public hospital tenders across Bulgarian administrative regions (Oblasts) demand high-volume availability, shelf-life integrity of at least 5 years, and multi-lingual user instructions (IFUs) packaged according to local health agency rules.
Export routes shipping into Bulgaria utilize direct sea container routes via the Port of Varna and Port of Burgas, or air-freight hubs in Sofia. Consolidated shipping options substantially lower landed costs per unit for regional distributors.
Our single-use respiratory masks and urinary catheter solutions are engineered to serve diverse clinical environments throughout Bulgaria's municipal, state, and private healthcare networks:
In mobile emergency ambulances (Бърза помощ) and emergency departments in Sofia and regional centers, multi-venturi mask kits enable paramedics to rapidly switch FiO2 settings using a single mask setup during trauma transport.
In specialized pulmonary wards (such as St. Sophia University Hospital), our fixed-diluter masks prevent hypercapnic crises by delivering non-fluctuating low-concentration oxygen to hypercapnic COPD patients under continuous blood-gas monitoring.
Post-anaesthesia care units rely on soft-molded, ergonomic PVC Venturi masks paired with star-lumen anti-crush tubing to ensure steady oxygen flow even if patient movement kinks the delivery line during recovery.
Founded in 1994, Angiplast Private Limited operates an advanced manufacturing ecosystem in Ahmedabad, India, specializing in high-volume, precision single-use medical devices. Over 80% of our production output is exported across 52+ international markets, supplying premier pharmaceutical entities, national health authorities, and private hospital networks.
Device molding, extrusion, tipping, high-frequency welding, and primary pouch sealing take place inside controlled, monitored cleanroom facilities to ensure ultra-low particle and bioburden baseline standards.
In-house Ethylene Oxide (ETO) sterilizers operate under fully validated computerized cycles. Every batch undergoes mandatory physical, chemical, and biological indicator release testing prior to shipment.
We empower Bulgarian importers with complete technical master files, Free Sale Certificates (FSC), ISO 13485 QMS audit data, biocompatibility reports (ISO 10993), and localized packaging support.
Clear, direct answers regarding regulatory compliance, shipping logistics, OEM options, and quality control.
Our entire manufacturing facility operates under an ISO 13485:2016 certified Quality Management System. Our products carry CE marking under European Council Directives/EU MDR routes, allowing direct lawful clearance and sales in Bulgaria and all EU member states. Furthermore, we issue Free Sale Certificates (FSC), ETO sterilization validation reports, and complete product technical files for Bulgarian Drug Agency (BDA) tender registrations.
Yes. Our in-house design and CDMO team manages custom pouch printing, inner shelf box artwork, outer export carton markings, and Instructions for Use (IFU) translated into Bulgarian. We also provide GS1-compliant UDI barcodes to support digital inventory tracking in Bulgarian public and private hospital supply systems.
Our standard Venturi mask configuration includes 2.1-meter (7-foot) star-lumen kink-resistant tubing crafted from clear, medical-grade, non-toxic PVC. The star-lumen internal wall design guarantees unimpeded oxygen flow even if the tube is accidentally twisted or compressed. We also offer DEHP-free and phthalate-free polymer formulations upon request.
Standard OEM or private-label minimum order quantities typically start at one full production lot per SKU (usually 5,000 to 10,000 units depending on packaging configuration). Standard catalogue orders ship within 3 to 4 weeks post-order confirmation. We support FOB, CFR, and CIF shipping terms to Black Sea ports (Varna, Burgas) or air cargo directly to Sofia International Airport.
Our 100% silicone Foley catheters feature biocompatible, inert material that minimizes urethral irritation and encrustation during extended dwell times. The smooth, hand-finished distal eyes prevent tissue trauma, while the symmetrical balloon inflates evenly to prevent catheter displacement in the bladder. Each lot undergoes 100% water-leakage and balloon-burst testing prior to pouch sealing.
