Hospital Central Oxygen System | Medical Gas Pipeline Infrastructure
The Hospital Central Oxygen System delivers continuous, medical-grade oxygen (93% +/- 3% via PSA or >= 99.5% via liquid oxygen source) to clinical delivery points. Engineered for centralized healthcare infrastructure, the system integrates gas generation/storage, automated pressure regulation, pipeline distribution, and zone valve control units into a unified architecture designed to meet ISO 7396-1 and HTM 02-01 operational mandates.

Key Features
Dual-Train Redundancy: Automatic switchover between primary and secondary supply sources ensures uninterrupted gas delivery during primary component maintenance or power interruption.
Medical-Grade Filtration: Multi-stage filtration train removes oil, moisture, and particulate down to 0.01 um, maintaining gas dew point below -40 deg C.
Real-Time Pressure & Purity Monitoring: Inline electrochemical sensors track oxygen concentration and line pressure continuously, triggering audible-visual alarms at the central nurse station if parameters deviate by +/- 5%.
Degreased Copper Piping Network: Distribution infrastructure utilizes ASTM B88 seamless copper tubes, chemically cleaned and degreased for oxygen service to eliminate combustion risks.
Applications
Operating Theaters (OR): Maintains strict pressure stability for anesthesia machines and surgical ventilators.
Intensive Care Units (ICU / CCU): Provides dedicated bedside drop-down service units for continuous mechanical ventilation.
Emergency Departments (ED): Rapid-response delivery zones equipped with high-flow therapy regulators.
Ward Nursing Stations: Zone valve service units (ZVSU) isolate specific floors for routine maintenance without disrupting other hospital wings.
Customization Options
Capacity Scaling: Modular PSA skids allow on-site addition of molecular sieve vessels to expand flow output as hospital bed capacity grows.
Power & Voltage Adaptation: Control cabinets configured for international electrical grids (220V to 480V, 50/60Hz).
Enclosure Types: Skid-mounted modular containerized systems available for rapid deployment in modular field hospitals or remote clinics.
Manufacturing & Quality Control
Welding Standards: All stainless steel and copper piping joints executed by certified welders holding ASME Section IX or EN 287-1 credentials using TIG inert gas backing.
Pressure & Leak Testing: Every pressure vessel and assembled manifold undergoes pneumatic leak testing at 1.5x operating pressure for 24 hours prior to factory dispatch.
Cleanroom Assembly: Critical gas-contact components are assembled and sealed in an ISO Class 7 cleanroom environment to prevent hydrocarbon contamination.
Certifications & Compliance
ISO 13485: Medical devices quality management system certification.
ISO 7396-1: Pipeline systems for compressed medical gases and vacuum.
CE Mark: Compliance with Medical Device Regulation (MDR EU 2017/745) requirements.
PED 2014/68/EU: Pressure Equipment Directive compliance for pressure vessels.
Packaging & Delivery
Packaging: Export-grade fumigation-free wooden crates with internal shock-absorbing EVA foam blocks; electrical panels sealed in moisture-barrier anti-static foil with silica gel desiccant.
Port of Loading: Shanghai / Ningbo, China (FOB / CIF / DDP terms available).
Lead Time: Standard configurations ship within 35 - 50 days; custom multi-bed infrastructure projects require 60 - 90 days engineering and production schedule.
FAQ
Q: What is the standard backup configuration required for hospital accreditation?
A: International standards (ISO 7396-1) mandate a three-source philosophy: a primary supply source, a secondary (automatic reserve) source, and a tertiary emergency reserve (such as a high-pressure cylinder manifold) to guarantee 100% operational uptime.
Q: How is the oxygen purity monitored inside the pipeline network?
A: Purity is monitored downstream of the generation plant using electrochemical or paramagnetic sensors. If purity drops below the safety threshold (typically 90%), the system automatically diverts to the backup source and activates remote alarms.
Q: Are the distribution pipes supplied with the system?
A: Yes. We supply the complete turnkey package including source equipment, control valves, alarm panels, and degreased medical copper pipes and fittings upon project request.
