Gez Medical Instruments Oxygen Regulator Analysis Report
Device Identification
The product in the image is an Oxygen Regulator used for medical oxygen cylinders, which reduces gas pressure and adjusts the flow rate. It is often also referred to as an “Oxygen Manometer” or “Pin Index Regulator”.
Brand and Model
Upon detailed examination of the inscriptions on the product, the brand GEZ MEDICAL INSTRUMENTS, written vertically on the side of the body, is clearly legible. The phrase “Brass Integral 50 PSI” located in the technical specifications section on the side surface of the product and the flow adjustment mechanism at the bottom confirm that the product is a standard “Click Style” oxygen regulator belonging to the brand.
General Condition
The product generally appears to be well-preserved and in a clean condition. There are no prominent deep scratches, paint flaking, or oxidation marks on its blue anodized coating. The gauge glass is intact and unbroken. The product is observed to be second-hand but in a ready-to-use condition.
Technical and Label Information
The technical data and warnings identified on the device are as follows:
- Brand: GEZ MEDICAL INSTRUMENTS
- Pressure Warning: The manometer display shows the warning “OXYGEN USE NO OIL”.
- Gauge Scale: The pressure gauge is graduated in PSI units and has a red “REFILL” zone.
- Technical Inscriptions: The body features the inscription “Brass Integral 50 PSI O2 Reg”. Additionally, “Inlet: CGA 870” indicates that the inlet connection conforms to Pin Index standards (CGA 870).
- Flow Indicator: The number “25” is visible in the bottom flow window, indicating that the device’s current setting is for a flow rate of 25 liters per minute or that it can reach this capacity.
Mechanical and Physical Examination
The physical components of the device have been analyzed as follows:
- Body: The blue aluminum body appears sturdy.
- T-Handle: The black plastic-headed clamping handle located at the top is robust and used to secure it to the cylinder.
- Outlet Port: The metal hose outlet (barbed outlet) located on the right side of the body is not bent and appears clean. It is suitable for attaching an oxygen mask or cannula.
- Manometer: The manometer, situated within a black protective plastic cover, is clean and legible.
- Flow Adjustment Knob: The black knurled section at the very bottom of the device is the mechanism used to adjust the flow rate (Liters/Minute), and no physical damage is observed on it.
Areas of Use
This product is used in hospitals, ambulances, home care services, and emergency interventions. It reduces high-pressure gas from medical oxygen cylinders to a safe pressure and flow rate (LPM) that the patient can use, delivering it to the patient via a mask or cannula.
Quantity Information
There is 1 (one) oxygen regulator in the images.
Potential Failure Risk
No critical malfunctions or deficiencies (e.g., broken parts, cracked body) were detected during the visual inspection of the device. However, the functionality of the mechanical flow adjustment knob and the internal accuracy of the manometer cannot be verified solely through visual analysis. As it is a medical device, it is recommended that leak tests and calibration checks be performed before use.
