<p>#CMT# #/CMT# Injection or infusion needle has a handle (6) for sliding or holding the protector (3) between the protector (3) and needle holder (1) #CMT#USE : #/CMT# Used for preventing potentially deadly needle injuries. #CMT#ADVANTAGE : #/CMT# The design improves on prior art by assisting manual operation, avoiding the danger of injury. The protector automatically adopts the protective position during withdrawal, with no additional intervention. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# A cross section of the design is presented. 1 : Needle holder 3 : Protector 6 : Handle 7 : Hollow cylindrical section 8 : Shield 11 : Radially projecting ribs #CMT#MECHANICAL ENGINEERING : #/CMT# Preferred device: The handle has a hollow cylindrical section (7) guided on the needle holder to prevent contact between finger and needle, when retracting the latter. At the far end of the section there is a shield (8). At the far end of the needle holder, radially projecting ribs (11) have a greater diameter than the protector (3). The handle (6) includes a ring at the near end.</p> |
