Needle assembly for drug pump

Apparatus (110) comprising:

• an activation mechanism (20) operative to deploy a needle (116) to protrude out of a housing (112);
• and
• a safety latch (122) movably mounted on said housing (112) and formed with a needle opening (129) to allow said needle (116) to pass therethrough, wherein said safety latch (122) has a first position wherein said needle (116) is aligned to pass through said needle opening (129) and a second position wherein said safety latch (122) is moved with respect to said housing (112) and said needle (116) is blocked by a portion of said safety latch (122) distanced from said needle opening (129).

A pump (110) for administering a fluid to a subject comprising;

• a housing (112);
• a needle holder (118) including a needle (116) having a distal end, the needle holder (118) being movable within the housing (118) from a first position in which the needle (116) is located entirely within the housing (112) and a second position in which at least the distal end of the needle (116) extends outside of the housing (112) for engaging the skin of the subject and administering the fluid to the subject;
• a safety latch (122) including a needle opening (129) extending therethrough, the safety latch (122) being movable from a first position in which the safety latch (122) is flush with a surface of the housing (112) with the needle opening (129) aligned with the distal end of the needle (116) so that when the needle holder (118) is moved to the second position the needle (116) extends through the needle opening (129), out of the housing (112) and into engagement with the skin of the subject and a second position in which at least a portion of the safety latch (122) is separated from the housing surface, the needle opening (129) is not aligned with the distal end of the needle (116) and a portion of the safety latch (122) engages and blocks access to the distal end of the needle (116).
