INJECTION UNIT FOR ADMINISTERING OR DELIVERING FLUID PRODUCT

摘要

#CMT# #/CMT# The injection device has an axially movable piston rod that is mounted in a housing (105) and is moved by a conveyor for dispensing fluid. A receptacle is mounted in housing to receive fluid product. A dosing device is detachably connected with the conveyor through a coupling mechanism (110) to dispensing fluid. The teeth-bearing coupling surfaces are formed in the coupling mechanism to produce acoustic or tactile signals corresponding to adjusted or corrected dose of the product during dose dispensing process or dose correction process. #CMT#USE : #/CMT# Injection device for dispensing fluid product. #CMT#ADVANTAGE : #/CMT# The conveyor and dosing device are coupled simply through coupling mechanism and relative movement between conveyor and dosing device can be prevented. The feedback signal about the adjusted dose of the fluid product is provided to the user. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of the coupling arrangement of injection device. 9 : Threaded sleeve 105 : Housing 110 : Coupling mechanism 111a : Rotary knob 115 : Click disc.
