Plug-in Stationary Low-Pressure Continuous Suction Device (Saliva Suction Device) and Tube Set (3 pieces)

This is an AC-powered continuous suction device. Please note that connectors for use with items like Merya tubes are not included and must be purchased separately.
The unit is in good condition, but has been used for approximately one month. It is being sold because it is no longer needed.
*Please be sure to use this device with the dedicated tube and a plastic bottle attached.
Three sets of tubes and plastic bottle caps for connecting to the bottle are included.

The suction strength can be adjusted.
We are unable to provide detailed explanations of the device's functions. We kindly ask that only those who understand this product purchase it.

▼ To ensure long-term use of your low-pressure continuous suction device, please be aware that if saliva collected in the plastic bottle or water droplets in the tube are drawn into the pump, it can cause malfunction and shorten the device's lifespan.
The following tips can help reduce the risk of suction and are highly recommended:

Tube Modification
Modify a tube with a cap and connect two plastic bottles. The second bottle will act as a safety bottle, reducing the risk of overflow.

Plastic Bottle Size
Use larger plastic bottles. To prevent foamy saliva from being sucked in, adding a small amount of water to the bottle can lower viscosity and be effective.

Plastic Bottle Type
Use rigid plastic bottles. Soft plastic bottles may collapse or deform under suction pressure.

Pump Placement
Condensation can form inside the tube due to temperature differences. To prevent water droplets from being drawn into the tube, we recommend placing the pump unit higher than the user's head.
