FORCING-OUT SYSTEM FOR CONTROLLED LIQUID INFUSION

摘要

FIELD: medicine. SUBSTANCE: system has tubular capsule closed at rear end with piston which can be forced in by means of rod moving inside vessel in direction of its axis in order to force out liquid through outlet hole located in front end of vessel. Piston rod is made flexible and incompressible. It deflects from capsule axis directly behind rear end of capsule preferably through 180 deg. by means of piston rod guide. The latter includes guide channel with curvilinear section and rectilinear sections at every end of curvilinear section. Parallel lengths of piston rod project from its guide. Length of guide channel in direction of projecting lengths, if counted from its ends to middle of piston rod in curvilinear section, is not less than space between axes of projecting lengths. System is convenient for use. EFFECT: reduced sizes of construction. 17 cl, 2 dwg
