Fluid product e.g. pharmaceutical product, distribution device e.g. vaporizer, has guiding pieces to guide free ends of arms along cam paths which present portions inclined relative to longitudinal axis, and needle cooperating with lips

摘要

#CMT# #/CMT# The device has a cam system comprising guiding pieces integrated to a receptacle (2) and adapted to guide free ends of arms along main cam paths between rest and course end positions. The paths present portions inclined with respect to a longitudinal axis such that the movement of a driving piece (10) in the longitudinal axis is lower than the movement of the arms. A needle projecting from a distribution orifice (6) and traversing a slot cooperates with cut out lips. #CMT#USE : #/CMT# Used for distributing fluid product e.g. pharmaceutical product, in the form of drop (claimed) in an eye. #CMT#ADVANTAGE : #/CMT# The device permits to distribute a predetermined quantity of product in the form of drop, and to cut out the drop after being ejected from the device. The device prevents the air from contacting the product before injection, thus avoiding the usage of anti-oxidants which imposes the utilization of filter for filtering the anti-oxidants during the ejection of the product. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial and sectional schematic view of a distribution device along a vertical and longitudinal symmetry plane. 1 : Distribution device 2 : Receptacle 6 : Distribution orifice 10 : Driving piece 25 : Arms 25c : Free end.
