I.V. Administration set with retrograde volume

摘要

An I.V. administration set is provided with a flexible expansion section so as to accommodate an additional volume of liquid without the use of excessive lengths of tubing. The expansion section is in the form of pleated or corrugated tubing which, upon the introduction of liquid into an I.V. set such as by means of a hypodermic syringe, will accommodate an additional portion of liquid which is known in the I.V. administration art as a retrograde volume.
