1. Wide range of application
3 water supply mode: instrument channel, water jet, and therapeutic device
3 water supply mode

Via instrument channel inlet

Via water jet inlet

With therapeutic device (FlushKnife Slim:DK2620JI and DK2623JI)
By flushing water from JW-3, the mucous membranes and lesions of the digestive tract are washed, supporting the ease of endoscopic diagnosis and treatment. JW-3 has 3 water supply mode:
- via endoscope-instrument channel inlet.
- via endoscope-water jet inlet.
- through FlushKnife Slim (DK2620JI and DK2623JI).
This system can be used for a wide range of applications from examinations to treatment including ESD (Endoscopic Submucosal Dissection).
High performance for water irrigation
JW-3 main unit recognizes which tube is connected by the tube detector connector joint attached to each tube.
The drive of pump motor is controlled according to the detected tube.In addition, different water flow rates are designed for each tube with the aim of achieving both comfortable water response and stop performance and supporting endoscopic procedures.
Water Flow Rate
Water Flow Rate | |
---|---|
A:Instrument channel tube | 400-700 mL/min. |
B:Water jet tube | 60-190 mL/min. |
C:Disposable therapeutic tube | 80-190 mL/min. |
Detected Tube Display

B:Light when water jet tube is connected
C:Light when disposable therapeutic tube is connected
2. Various devising for usability support smooth examination and treatment

3. For infection prevention and safety
Autoclavable tubes and water tank, Disposable tubes

Tip of JT-3DT to connection to saline bag
Both tubes (JT-3RC, JT-3RC2, and JT-3RW)and water tank are autoclavable for effective sterilization and are re-usable. In addition, sterilized disposable tube (JT-3DC, JT-3DW, and JT-3DT) can be selected in view of infection management of hospital.
A lineup for therapeutic device (FlushKnife Slim:DK2620JI and DK2623JI) connection tube capable of submucosal injection
JT-3DT, designed for therapeutic device (FlushKnife Slim:DK2620JI and DK2623JI) is a disposable tube that connects to a saline bag via a port connector. By combining this tube with FlushKnife Slim:DK2620JI and DK2623JI, it’s possible to inject saline solution into the submucosal layer in ESD treatment.
For safety use, to avoid human error
If the cover of the pump head is opened during operation, operation is automatically stopped to protect users from injuries and accidents.
The tube detector automatically recognizes which tube is set. In consideration of safety use, the maximum flow rate is set for each tube. During continuous flowing, water supply is automatically stopped once at the set time for each type of detected tube. These are designed to avoid human error.
Max. Water Flow Rate and Automatic Cut-off Timer
Tube Type | Max. Water Flow Rate | Automatic Cut-off Timer |
---|---|---|
A:Instrument channel tube | 840 mL/min. | approx. 20-seconds |
B:Water jet tube | 220 mL/min. | approx. 20-seconds |
C:Disposable therapeutic tube | 209 mL/min. | approx. 8-seconds |
