Cylinder Body & Material 

 Adopts 6061 aluminum alloy and is manufactured by one-piece forging.Weld-free structure ensures uniform stress distribution and extremely high fatigue strength. Delivers safety redundancy and service life far exceeding industry standards, directly reducing the annual average equipment investment cost.

Safety Valve & Rupture Disc 

 Integrates an overpressure relief device (rupture disc).Enables directional and controlled pressure relief under extreme conditions (e.g., abnormal high temperature). It serves as the final and most reliable physical barrier to protect the safety of your department staff and patients, minimizing potential risks.

Valve & Interface 

 Precision-machined CGA 870 standard interface paired with high-performance sealing material.Ensures airtightness for every connection and maintains reliable performance even after repeated assembly and disassembly. Completely eliminates the risks of medical resource waste and oxygen supply interruption caused by slow air leakage, thus guaranteeing the effectiveness of treatment.

Humanized Protective Ring & Labeling Area 

 Large-area smooth design on the cylinder shoulder, coupled with a detachable protective ring.Provides ample, flat space for label application, and the protective ring can be easily assembled and disassembled for label replacement. Makes your asset identification and expiration date management clear at a glance, helps you easily comply with strict quality audits, and achieves refined management.

Three major application scenarios for small portable oxygen cylinder

Scene One: Hospital Department Transfers and Ward Rounds

Provide standardized oxygen support for in-hospital patient

In daily hospital operations, patients frequently need to be transferred between departments. Disorganized oxygen supply methods or mismatched equipment can lead to treatment interruptions, increased workload for nursing staff, and potential safety hazards. Unstandardized cylinder appearances also complicate asset identification and inventory management.Midstar small portable oxygen cylinders adopt unified and standardized specifications with clear labels, facilitating quick identification, counting and circulation among departments. The lightweight body and anti-slip base ensure stable mobility and simple operation. Aerospace-grade aluminum alloy has passed over 10,000 fatigue tests, significantly reducing long-term equipment replacement costs. Supporting custom department codes and labeling areas to meet strict quality audit requirements and achieve refined management.

Scene Two: Emergency Stockpiling and Rapid Response

Provide emergency-ready oxygen reserves for hospital emergency departments and disaster preparedness

Hospitals must maintain emergency oxygen reserves for scenarios such as mass casualty incidents, sudden respiratory disease outbreaks, or power outages affecting central oxygen systems. Emergency preparedness requires oxygen sources that are compact, easy to deploy and immediately available.Midstar small portable oxygen cylinders feature an integrated overpressure relief device (rupture disc) as the final reliable physical barrier to protect staff and patient safety. The precision-machined CGA 870 standard interface paired with high-performance sealing material eliminates risks of slow air leakage and oxygen supply interruption. The detachable protective ring and large labeling area ensure emergency stocks are always inspection-ready and immediately usable when needed.

Scene Three: Inter-hospital Patient Transport and Ambulance Backup

Provide portable oxygen solutions for ambulance transfer and nursing home evacuation

During inter-hospital patient transport, nursing home evacuations, or home-to-hospital transfers, oxygen cylinders must be compact, portable and capable of maintaining stable gas output during vehicle motion. Heavy or bulky cylinder Equipments failure during transport directly threatens patient safety.Midstar small portable oxygen cylinders are made of aerospace-grade 6061 aluminum alloy with a weld-free structure ensuring uniform stress distribution and extremely high fatigue strength. The lightweight design allows easy handling for medical staff in confined ambulance compartments. The cylinder shoulder provides ample flat space for custom labels, allowing transport teams to quickly verify contents and expiration dates before departure.
