Abstract: A medicant delivery method is to introduce a fluid into a container by flowing along a pressure-in pathway and out to the container. As a flow speed is stable, a connecting channel is plugged to enter the fluid to the pressure-out pathway. The fluid flows along the pressure-out pathway and then out into the container to convey the medicant at a container bottom out of the container. This method can provide more stable and more balanced forcing to gently carry the medicant all the way out of the container. Thereupon, contamination at an endoscope by the medicant bounced back from a target tissue to block vision of the endoscope can be avoided. Thus, medicant administration (hemostatic medicant for example) can be more accurate, continuity of an endoscopic surgery can be improved, performance in hemostasis can be raised, and also the total surgery time can be reduced.
