<p>PURPOSE:To allow a drip solution to perfectly flow out in a definite ratio by always stably deforming the shape of container for perfusion into a definite shape according to the outflow of the drip solution from the container, by forming the cross-sectional shape of the body part of the container into a special shape. CONSTITUTION:The cross-sectional shape of the body part of a bottlelike container 1 formed by blow molding is formed into an almost triangular shape to form three ridgelines to said body part inclined in the longitudinal direction of the container 1. The perfusion container 1 is set so as to direct the opening 2 thereof downwardly to guide a drip solution by a tube. As the internal pressure of the container 1 becomes low, the perfusion container 1 is gradually deformed under atmospheric pressure. Since the body part 3 is set to a shape outwardly expanding from the straight lines connecting the ridgelines, said body part is deformed so that the side surface parts between the ridgelines 4, 4', 4'' are deformed so as to be depressed inwardly. At the time of this deformation, since the ridgelines are inclined in the longitudinal direction, deformation like distortion is also added to the body part 3, the deformation, that is, the outflow of the drip solution is promoted.</p> |
