Oil-Free Piston Pump
The Medinain 25D uses an oil-free piston pump.
According to the supplied product description, this provides:
- Clean operation without oil and smoke pollution
- No need to add oil for daily maintenance
- Convenient routine operation
The oil-free design is intended to simplify maintenance while providing the specified suction performance.
Adjustable Negative Pressure
The Medinain 25D allows the user to select negative pressure as required, with the supplied description specifying no-level pressure adjustment.
It also incorporates an overflow protection mechanism, described as providing safe and reliable operation.
The specified maximum negative pressure value is >0.09 MPa, while the maximum vacuum is listed as 90 kPa.
Hand & Foot Switch Operation
The 25D features both:
This provides alternative operating methods depending on the clinical workflow and setup.
Dual Collection Jars
The apparatus is equipped with 2 glass jars for collection.
The supplied specification identifies the number of glass jars but does not provide an individual or combined jar capacity, so that information should be confirmed from the manufacturer if required.
Reverse-Flow Protection
The product description states that there is no flow-backwards pressure when the machine stops, helping prevent collected liquid from flowing backward through the suction system.
Overflow Protection
An overflow protection mechanism is included in the specified configuration.
This feature is intended to provide additional protection against fluid entering the pump system when the collection arrangement reaches its applicable limit.
Plastic Panel Construction
The Medinain 25D features complete plastic panels, according to the supplied product description.
