TQ-4 clinical application


1. Prior to initiating the procedure, visually inspect to ensure each connection of the Applicator is well connected by Luer connector.

2. Firmly insert the MPH Absorbable Hemostatic Particles nozzle into the mouth (A) of Y-junction (Fig.1).

3. Connect the connecting pipe 2 to gas source with constant airflow (16±3 kPa) to prevent any fluids from the reverse flowing into the catheter (Fig 2).

4. Insert the catheter through a working channel on the endoscope (Fig.3) and position the endoscope to the bleeding site. Avoid direct contact of the catheter tip with any fluids.

5. Select the gas source to obtain a lower airflow (12±3 kPa). Gently tilt Y-junction to deliver the powder to the site of bleeding via gently pressing MPH bottle (Fig.4). Avoid direct contact of the catheter tip with any fluids. If that unfortunately occurred, the MPH bellows applicator can be removed in a squeezed state which can improve occluded problem.

6. Remove the catheter from the endoscope immediately after hemostasis is achieved.
