A needle protection device including a needle holder for operable coupling to an injection device and from which an injection needle projects, a blocking device which projects from the needle holder and is radially distanced from the injection needle, a needle protection element which can be moved into a first position and, from the first position, to a protection position in which it surrounds the injection needle, and which can be blocked from leaving the protection position by the blocking device, and a safety member arranged between the injection needle and the needle protection element in such a way that it can be displaced in relation to the injection needle, wherein the needle protection element includes an engagement element and the safety member includes a counter-element, the engagement element and counter-element mutually engaging when the needle protection element is moved into the first position, the needle protection element thereby entraining the safety member during movement of the needle protection element into the protection position.

Needle protection device with a blocked protective position

A needle protection device detachably fixed to an injection appliance includes a needle, a needle holder from which a needle injection section of the needle projects distally and a needle connection section of the needle projects proximally, a distal needle protection element connected to the needle holder movable in the distal direction from a release position to a protection position and arranged behind the needle injection section in the release position and overlapping the needle injection section and distal end of the injection needle in the protection position, a proximal needle protection element connected to the needle holder movable from a release position and arranged behind the needle connection section into a protection position and overlapping the needle connection section and proximal end of the injection needle, and a blocking device which blocks movement of the proximal needle protection element from the protection position into the release position.

Needle protection device comprising a distal protection element and a proximal protection element

A needle safety module for being connected to an injection device for administering a liquid product to a patient, the module including a housing, a needle connected to the housing, and a needle protective sleeve having one end which can be placed on an injection point of the patient and displaced axially in relation to one of the needle or the housing from a starting position in which the needle tip is covered to an injection position in which the needle tip at least touches the injection point, the needle protective sleeve lockable in relation to one of the needle or the housing.

Needle safety module comprising a locking mechanism and a user identification

A needle protection device for use with an injection device, the needle protection device including a moveable needle protection element which moves through a release course of movement into a locking engagement position as a result of an elastic force, the locking engagement position being achieved when the needle protection element moves from a starting position to a triggering position, when the needle protection element moves over a small portion of the release course, and being maintained when the needle protection element is no longer subjected to an external force in the triggering position.

Needle protection device with a blocked protection position

A needle unit for an injection device comprising an injection needle and a needle holder, the needle unit coupled to the injection device and comprising: a needle protector comprising a guide which guides the needle protector such that it can move axially, at least one spring element applying a spring force to the needle protector thus holding the protector in a first position, and a lock which, after an injection, locks the needle protector in the first position against moving further axially, wherein the lock is deformable by force and assumes its original shape after said force is removed, and wherein the needle protector affects the lock transversely with respect to the axial movement direction during an axial movement of the protector which accompanies an injection and deflects the lock into a locking position when the needle protector is moved to the first position.

Needle protecting device comprising a lock

A needle protecting device on or for an injection apparatus comprising an injection needle with a needle tip and a needle base beyond which the injection needle protrudes, the needle protecting device including a needle protector moveable from an exposing position in which the needle tip is exposed to a protective position in which it overlaps the needle tip, a first blocking mechanism connected to or formed in one piece with one of the needle protector or the needle base, and a second blocking mechanism connected to or formed in one piece with the other of the needle protector or the needle base, wherein, when the needle protector is in the protective position, the blocking mechanisms are engaged with each other preventing the needle protector from moving into the exposing position, and wherein the engagement may be non-destructively released and/or restored.
