The application relates to a needle protection assembly () comprising: &#x2014;a supporting element () and a needle shield (), &#x2014;one locking element () located within said needle protection assembly () and not accessible to the user, &#x2014;urging means () for displacing said needle shield (), &#x2014;a peg () located on said supporting element () or on said needle shield (), and a cam () located on said needle shield () or on said supporting element (), and &#x2014;said locking element () is not formed by said peg () and cam (). The respective longitudinal axis of the needle shield () and of the locking element () are merged when said needle shield () is in its before use or in use positions, and they form an angle (a) when said needle shield () is in its after use position.

A simple method and device enabling a unit dose from a reservoir is provided. The dose is drawn into the reservoir and is then expelled from the device by depressing a plunger. The plunger has features which divide the dose into discrete intervals. As the plunger is moved during delivery, the features on the plunger and features connected to a barrel interact to provide for intermittent stops to the delivery. Other aspects of the device provide for reduced dead space, safety and selective interconnection with other devices. Thus, the device divides the dose.

The present invention relates to a needle assembly () to be used in combination with a storing device () comprising a barrel () defining a chamber () receiving a product () and a piston (), the assembly () comprising: &#x2014;needle-bearing portion () in a first material, movable between an exposed and a retracted positions of the needle (), &#x2014;engaging means (,) for securing said needle-bearing portion () to said barrel () in the exposed position, characterized in that it comprises: &#x2014;sealing means () in a second material for tightly sealing the distal end () of said chamber () to said needle-bearing portion (), &#x2014;a breakable portion () located between said engaging means (,) and said needle-bearing portion (), which, when broken, allows independent proximal displacement of said needle-bearing portion () relative to said engaging means (,) between said exposed and said retracted positions, said first material being more rigid than said second material. The invention also relates to an injection device () comprising said needle assembly () and a storing device ().

The application relates to a needle protection assembly () comprising:&#x2014;a supporting element () and a needle shield (),&#x2014;one locking element () located within said needle protection assembly () and not accessible to the user,&#x2014;urging means () for displacing said needle shield (),&#x2014;a peg () located on said supporting element () or on said needle shield (), and a cam () located on said needle shield () or on said supporting element (), and&#x2014;said locking element () is not formed by said peg () and cam (). The respective longitudinal axis of the needle shield () and of the locking element () are merged when said needle shield () is in its before use or in use positions, and they form an angle (a) when said needle shield () is in its after use position.

A medical device includes a syringe assembly and a shield system for delivering medicament to a patient. The syringe assembly includes a barrel defining a medicament reservoir, and a needle cannula coupled to the barrel and in fluid communication with the reservoir. The shield system has a hub coupled to the syringe barrel, a shield movably arranged on the hub, the shield being movable from a first position disposed from the needle cannula tip to a second position during insertion of the needle into a patient and movable from the second position to a third position covering the needle cannula tip after the needle cannula is removed from the patient. An urging member urges the shield to the third position upon removal of the needle cannula from the patient. A cover sleeve connected to the needle barrel surrounds the hub and the urging member.
