Angiographic syringe for delivering contrast liquid product to establish e.g. magnetic resonance imaging, has buffer deflector for orienting flow of product entering in conduit in axial direction towards internal surface of body's side wall

摘要

#CMT# #/CMT# The syringe (1) has a body (3) forming a product reservoir and comprising a converging middle part (7) and a distal part forming a conduit (9) for entering and exiting liquid product. The conduit includes a buffer deflector (21) for orienting flow of product entering in the conduit in an axial direction (19) towards an internal surface of a side wall of the body. The buffer deflector includes helical grooves (25) inclined with respect to an axis of the conduit and arranged along the length of the buffer deflector. The deflector and the body are formed by a single piece through molding. #CMT#USE : #/CMT# Angiographic syringe for delivering contrast liquid product to establish medical imaging diagnosis such as radio nuclide scanning and magnetic resonance imaging. #CMT#ADVANTAGE : #/CMT# The buffer deflector permits to orient the flow of product entering in the conduit in the axial direction towards the internal surface of the side wall of the body, thus preventing occurrence of bubbles in the body of the syringe by suppressing front percussion of the flow of product on joint of piston, during the filling of product in the syringe. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of an end of syringe. 1 : Angiographic syringe 3 : Body 7 : Converging middle part 9 : Conduit 19 : Axial direction 21 : Buffer deflector 25 : Helical grooves.
