ADVANCED CONJUGATION OF LOCK OF FLOW FOR MEDICAL INSTRUMENTS Russian patent published in 2006 - IPC A61M5/142 

FIELD: medicine; facilities for intravenous injection.

SUBSTANCE: deice has plate disposed between external door and pump mechanism. Plate is disposed in such a way that when pushing external door of pump into closed position it moves the plate for disposition of tube for fluid flow in closing contact with pump mechanism, before the plate makes contact with flow lock, which is made together with tube, and releases lock of flow to provide fluid flow going and to exclude the state of free flowing. Door also has release lever with hook, which engages with lock of flow when door is at closed position. When door opens, the hook moves floe lock into closed position before the plate shifts from tube to prevent the condition o free flow. Plate has part for releasing flow lock, which part is shifted from the rest part of plate and which makes contact with release lug at flow lock to provide motion of flow lock to position of fluid flowing. Plate is mounted onto case by means of floating hinge and basic pins disposed onto edge surface of pump mechanism for precise positioning of plate relatively pump mechanism which results to precise positioning of tube for fluid.

EFFECT: reliable overlap of tube for intravenous injections.
