An injection device for dispensing a dose of a product by manually advancing a piston rod includes a dosing and dispensing mechanism having a housing with a longitudinal axis, a dosing sleeve mounted in the housing for adjusting and correcting the dose, a housing insert fixed to the housing and arranged inside the dosing sleeve, and a coupling sleeve mounted in the housing for driving the piston rod. For setting and correcting a dose, the dosing sleeve is rotatable relative to the coupling sleeve, and for dispensing the dose, the dosing sleeve can be coupled to the coupling sleeve in a rotationally fixed manner. In this case, the coupling sleeve has a locking element which can interact with the housing insert so that the coupling sleeve can be rotated in a first direction of rotation and cannot be rotated in a second direction of rotation relative to the housing insert.

Dosing system for an injection device

A dosing system for an injection device for dispensing a dose of a product includes a housing having a longitudinal axis, a dose-setting element, a holding element and a coupling sleeve for driving a driving device for dispensing the dose. The dose-setting element, holding element, and coupling sleeve may be accommodated in the housing. To set and correct the dose, the dose-setting element and the coupling sleeve move in the direction of the longitudinal axis relative to the housing, and the coupling sleeve may be held the holding element rotationally fixed by relative to the housing. To dispense the dose, the coupling sleeve may rotate relative to the housing, the dosing system including a guide in the housing, in which guide the holding element may be displaced in the direction of the longitudinal axis relative to the housing and be guided in a rotationally fixed manner relative to the housing.

A modular device for administering a fluid medicament fixable to the skin of a user includes a reservoir module with a reservoir defining a first axis, a first connecting structure and a first electrical contact arrangement; and a pump module with a piston rod defining a second axis, a second connecting structure arranged around the piston rod, and a second electrical contact arrangement. The first and second connecting structures are plugged together and the first axis and the second axes lie on a common axis forming a rotational axis. The pump module is rotated relative to the reservoir module about this rotational axis to electrically connect the first and second electrical contact arrangements. The first contact arrangement is displaced radially farther from the first axis than the first connecting structure, and the second electrical contact arrangement is displaced radially farther from the second axis than the second connecting structure.

Modular administration appliance

A piercing device for an administration device includes an elastic element with which a biasing force may be generated for piercing, a base, and a cannula unit which may be movable relative to the base in a piercing direction from a safety (secured) position, where the cannula unit may be subjected to the biasing force in the piercing direction. The administration device further includes a securing element by which the cannula unit, subjected to the biasing force, may be held in the safety position and which has a thermosensitive region that may be deformable under mechanical stress when heated, and a heating element with which the thermosensitive region of the securing element may be heated, such that the thermosensitive region of the securing element may deform in response to the biasing force and, as a result, the cannula unit may move away from the safety position in the piercing direction.

Piercing device for an administration device

An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

Dual-function spring

A fill port for filling a liquid medicament into a reservoir located inside a drug delivery device includes insert fixed in a passage of a wall of the drug delivery device, and a pierceable fill port sealing is sandwiched between the insert and both the housing of the drug delivery device and the reservoir to provide a fluid-tight sealing between the reservoir and the housing.

Wearable drug delivery device

An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.

Device for administering a fluid product

A modular, semi-disposable patch pump for conducting a medical therapy includes a pump unit releasably connected to a reservoir unit by means of a bayonet connection; and a housing design for supporting both reliability and ease of use of said connection.

An insertion mechanism for a cannula includes a cannula housing, a displaceable cannula, at least one cannula holder, an insertion spring, a triggering element, and a safety device. The safety device, in a secured state, holds the triggering element in a blocked position against a force of the insertion spring and, in a released state, releases the triggering element such that the triggering element is movable into a release position by the force of said insertion energy store and the at least one cannula holder is able to move relative to the cannula housing, driven by the insertion energy store, so as to trigger or implement an insertion movement or insertion. To reach the released state, the safety mechanism is heatable by a heating element and softened and/or weakened with respect to its mechanical carrying or holding capacity, or severed or at least partially or completely melted.

Cannula insertion mechanism

An autoinjector for dispensing a liquid product, in particular a highly viscous medication, includes: a housing, a product container, which is arranged in the housing and has a slidable piston, wherein the piston can be slid in a dispensing direction in order to dispense the product contained in the product container, a forward drive element, which acts on the piston as the product is being dispensed, a first spring, which is preloaded such that the product can be dispensed from the product container by the sliding of the forward drive element and the piston, and a rotation element, which is operatively coupled to the forward drive element, wherein the first spring acts on the rotation element in such a way that the rotation element is set into rotation in order to dispense the product, wherein the rotation element or the forward drive element has a thread having a variable pitch.

Injection device having a thread having a variable pitch

A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.

Dosing mechanism for an injection device for administering a product

An injection device having a delivery element with an inner thread may be driven by rotation and includes a cylindrical outer wall region, which is substantially smooth. Such features provide a delivery element configured such that it is less intimidating to patients than known threaded rods, and may facilitate easy cleaning. The delivery element may be non-rotatably guided and axially spring-loaded, and may be inserted axially into the housing when the reservoir is replaced. The driving thread element for the delivery element may be mounted in the vicinity of the distal end of the housing.

A disposable module that can be coupled to a reusable module in order to form a pump for dispensing a medicament substance to a user in a metered manner in a coupled state, comprising a housing that encases the following components: a reservoir for receiving the substance to be dispensed; and at least one extensible cannula, which is fluidically connected to the reservoir either after being inserted or in a permanent manner. The disposable module may also comprise an electrical energy store, wherein the electrical energy necessary for the reusable module can be obtained both from the disposable module and also from a rechargeable battery in the reusable module, in order to ensure redundancy of the energy necessary for the reusable module.

Patch pump

A segmented piston rod for an injection device includes multiple segments joined together via a hinge located on one side of each segment. The piston rod can be bent in one direction by articulating subsequent hinges while an axial force can be transmitted by the segmented piston rod to the stopper when the subsequent hinges are closed and the segments abut each other opposite to the one side of the hinge. The segmented piston rod is secured against rotation relative to the housing around the longitudinal axis of the segmented piston rod. The segmented piston rod has a last element which abuts the stopper in the reservoir and a first segment which is opposite to the last segment. The first segment is includes an internal thread matching an external thread of a drive sleeve and rotation of the drive sleeve advances the piston rod towards the stopper of the reservoir.

Segmented piston rod for a medication delivery device

A coupling mechanism for a medication delivery device includes a first part axially fixed relative to a housing and rotatable around a longitudinal axis of the first part, the first part having a gearing engagement to a second part arranged along the longitudinal axis, the gearing engagement having a first frictional resistance. The second part axially moveable along the longitudinal axis, and directly or indirectly in a friction fit engagement with the housing, which has a second frictional resistance. The first frictional resistance being below the second frictional resistance such that a rotation of the first part in a first direction axially longitudinally moves the second part away from the first part and a rotation in a second direction, opposite to the first rotation direction, reduces the axial distance between the first and second part and/or axially moves the second part into coupling abutment with the first part.
