摘要:
Disclosed herein is a drug delivery device with a primary drug delivery assembly for the delivery of a primary medicament, with a primary dose setting member; and a secondary drug delivery assembly for the delivery of a secondary medicament with a secondary dose setting member. A dose dial is rotationally constrained with respect to the housing in a first axial position and is rotationally constrained to the primary dose setting member in a second axial position. A bridging component is axially constrained to the dose dial to set a dose of the secondary medicament, wherein rotation of the dose dial to set a dose of the primary medicament causes the dose dial to move relative to the bridging component in axial direction.

A locking structure for an injection pen. The locking structure for an injection pen is disposed among a spiral duct (30), a push rod (81) and a propelling lever (60) of a circularly-pushing device (1) of the injection pen. The propelling lever (60) penetrates in a tube center hole (331) of a linkage wall (33) in the spiral duct (30) by means of a dosage control section (63) having a push thread (631). The push rod (81) penetrates in the propelling lever (60) by means of a rod portion (811). The locking structure comprises a necking ring portion (36), a buckling recessed portion (814), and an elastic clasp (612). The necking ring portion (36) is formed at the rear side surface of the linkage wall (33) in the spiral duct (30). The buckling recessed portion (814) is formed in the front section of the rod portion (811) of the push rod (81). The elastic clasp (612) is formed in the rear end of the propelling lever (60) adjacent to the dosage control section (63).
摘要:
A dosing device for setting a dose to be delivered by an injection device, the dosing device including a setting element, e.g. a setting sleeve, and a drawing element, e.g. a rotating sleeve, which can be rotated out of the dosing device for preparing a dose delivery. A stop is on the setting element, and a counter stop is on the drawing element so that a rotational motion of the drawing element relative the setting element can be limited by the stops. The present invention encompasses a method for setting a dose that should be delivered by an injection device, wherein the dose to be delivered can be set by a setting element, e.g. a setting sleeve, and a drawing element of the injection device, e.g. a rotating sleeve, can subsequently draw up the dose by effecting a rotational motion to deliver the set dose from the injection device in a subsequent step. According to the present invention, the setting process is isolated from drawing process.

A threaded rod for an injection device, wherein the rod includes a thread on an external surface, the thread supporting or carrying, at least partially, engaging elements and/or teeth. In one embodiment, the present invention encompasses a dosing mechanism for an injection device, including a rotational defining element which enables a threaded rod to be rotated in one direction, rotation being blocked or prevented in the counter direction by at least one blocking element which co-operates with a thread of the threaded rod, wherein the thread carries, supports or has associated teeth and/or engaging elements. In one embodiment, the present invention encompasses an injection device including at least one engaging element which co-operates with a blocking element associated with a threaded rod, whereby the threaded rod is rotatable in one direction in relation to the injection device, rotation in the opposite direction being prevented.

摘要:
A safety injection device, such as a hypodermic needle, for dispensing liquid from a cartridge in quantities determined by the length of a plunger which may be selectively adjusted in one position only of the plunger. The plunger comprises first and second threadedly connected sections cooperating with a connector which may be selectively activated when the plunger is moved into the one position to permit rotation of one plunger section relative to the other. Preferably, the adjustment position of the plunger coincides with its positions assumed in preparation of an injection stroke, with the connector preferably providing for undirectional rotation of the one plunger section.

A setting mechanism for a dosing device, in particular for a device for dosing pharmaceutical or therapeutic substances, the setting mechanism including: a controlling assembly for connecting the setting mechanism with a dose setting element of the dosing device; a driving assembly for connecting the setting mechanism with a driving element of the dosing device; a dosing assembly for connecting the setting mechanism with a dosing element of the dosing device. The controlling assembly is coupled with the dosing assembly by a spring element, which can deform from a coupled position to a decoupled position during rotation of the dose setting element. The spring element is configured to allow a displacement of the controlling assembly with respect to the dosing assembly. In the coupled position the spring element is configured to block a rotation of the controlling assembly with respect to the dosing assembly.

An indication assembly (100) is presented. The indication assembly (100) comprises indication members (110, 120) further comprising interaction features (111, 121). The indication assembly (100) comprises a locking member (130) which is movable with respect to the indication members (110, 120) between a locking position and a non-locking position. The locking member (130) comprises a locking member feature (131), wherein the indication members (110, 120) are rotatable relative to the locking member (130) around an axis (x). The indication assembly (100) is configured such that when the locking member (130) is in the non-locking position, the indication members (110, 120) are rotatable by a predetermined angle in a first rotational direction. The indication assembly (100) is configured such that when the locking member (130) is in the non-locking position and the indication members (110, 120) are rotated by the predetermined angle with respect to the locking member (130), the locking member feature (131) interacts with the interaction feature (111) such that the locking member (130) is displaced into the locking position.
