Drug delivery devices may aim to make self-injection easier for patients. Drug delivery devices that use electronic components are becoming more and more popular in the pharmaceutical industry and for users or patients. Electronically measuring the dose delivered can make the use of drug delivery devices more comfortable. Summary of the Invention [Problem to be solved by the invention]

[0003] One of the objectives to be achieved is to provide an improved electronic component for a drug delivery device. Preferably, the electronic component allows a sensor to be mounted securely and precisely on the drug delivery device. Further objectives to be achieved are to provide an improved mounting member for the electronic component, an improved mechanism for the drug delivery device, an improved drug delivery device, and an improved method for assembling an apparatus for the drug delivery device. [Means for solving the problem]

[0004] These objects are achieved, inter alia, by the subject matter of the independent claims. Advantageous embodiments and further developments are the subject matter of the dependent claims and can also be derived from the following description and figures.

[0005] First, the electronic components for the drug delivery device are presented.

[0006] In accordance with at least one embodiment, an electronic component includes a carrier having a mounting section and a sensor section, the sensor section being connected to the mounting section via a connection region.

[0007] The connection region is specifically part of the carrier. The connection region may be directly adjacent to the sensor section and / or the mounting section. For example, in the connection region, the mounting section is directly adjacent to the sensor section. The connection region may be a continuous, preferably simply connected, region or section of the carrier. For example, the sensor section is connected to the mounting section only via the connection region or only in the connection region.

[0008] The carrier may be a connection carrier including one or more electrical conductors. The carrier may include an insulating base body, for example formed from plastic. The mounting section and the sensor section may each be partially formed by the base body. The base body may be formed in one piece or may be integrally formed. The base body may extend continuously from the mounting section over the connection region to the sensor section. One or more conductive tracks may be arranged on the base body and / or may be integrated into the base body. At least one of the conductive tracks may extend from the mounting section through the connection region to the sensor section. The carrier may be a printed circuit board, PCB for short.

[0009] Here and hereinafter, when the terms "connected" or "connects" or similar terms are used without specification by a prefix such as "mechanical" or "electrical", these terms specifically refer to a mechanical connection.

[0010] According to at least one embodiment, a sensor is disposed in the sensor section. For example, the sensor is electrically connected to the carrier in the sensor section. The sensor can be electrically connected to one or more conductive tracks of the carrier. The sensor can be fixed to the carrier in the sensor section. The sensor can be soldered or glued to the sensor section. The sensor can be a non-contact or contactless sensor. That is, the sensor can be configured to perform a sensing operation without physically contacting an object on which the sensing operation or measurement needs to be performed.

[0011] According to at least one embodiment, an electric element is arranged in the mounting section. The electric element can be electrically connected to the sensor. The electric element can be electrically connected to the carrier in the mounting section. For example, the electric element is electrically connected to one or more conductive tracks of the carrier. The electric element can be electrically connected to the sensor via one or more of the conductive tracks. The electric element can be fixed to the carrier in the mounting section. The electric element can in particular be soldered or glued to the mounting section. The carrier can in particular mechanically carry the sensor and the electric element and / or electrically connect the electric element and the sensor, for example via the conductive tracks.

[0012] The electrical element may for example be an electrical control unit or a processor or element of a wireless communication module, for example a Bluetooth module. In particular, the electrical element may be configured to exchange electrical signals with the sensor. For example, the electrical element is configured to operate and / or activate the sensor and / or receive measurement signals from the sensor and / or electronically process the measurement signals.

[0013] According to at least one embodiment, the sensor section is movably arranged relative to the mounting section. In particular, the sensor section can be movable relative to the mounting section between a first position and a sensing position. The first position can be a position to which the electronic component is delivered and / or a position prior to assembling the electronic component to an apparatus for a drug delivery device. The sensing position can be a position for operating the sensor and / or a position to which the electronic component is assembled to an apparatus for a drug delivery device.

[0014] Movable preferably means that the sensor section is arranged pivotably and / or bendably and / or foldably relative to the mounting section. For example, at least in the connection region, the carrier is formed to be flexible or bendable to allow a relative movement between the mounting section and the sensor section. The connection region can be formed by a hinge connection, for example a film hinge connection. For example, the carrier is a so-called flexible board. The movement from the first position to the sensing position and / or from the sensing position to the first position can be reversible.

[0015] When moving the sensor section from the first position to the sensing position relative to the mounting section, the sensor section can pivot at least 45° or at least 80°, such as 90°, relative to the mounting section. Additionally or alternatively, the sensor section can pivot up to 135° or up to 100° between the two positions.

[0016] The carrier may be thin. For example, the thickness of the carrier, measured between the front side and the rear side of the carrier, is smaller, for example at least 5 times smaller or at least 10 times smaller, than the extent of the front side or the rear side. In the first position, the main extension plane of the mounting section may be parallel or approximately parallel to the main extension plane of the sensor section. For example, in the first position, the angle between the main extension plane of the sensor section and the main extension plane of the mounting section is at most 10° or at most 5°. In the sensing position, the main extension plane of the sensor section and the main extension plane of the mounting section may be inclined to each other, for example perpendicular to each other. For example, in the sensing position, the angle between the main extension plane of the sensor section and the main extension plane of the mounting section is at least 45° or at least 80°.

[0017] The terms "main extension plane" and "main extension direction / axis" are known to those skilled in the art. In particular, the main extension plane of an element may be a plane fitted through the element, for example by chi-square optimization. The main extension direction may therefore be the direction of a line, for example a straight line, fitted through the element. Such a straight line may define the main extension axis.

[0018] The electrical components and the sensors may be located on different sides of the carrier, for example the sensors are located on the back side of the carrier and the electrical components are located on the front side of the carrier.

[0019] According to at least one embodiment, in the sensing position, the sensor is axially offset compared to the first position. "Axially offset" means axially offset. This means that movement of the sensor section from the first position to the sensing position includes axial movement of the sensor. In particular, in the sensing position, the sensor is further axially offset relative to the mounting section and / or the electrical element than in the first position.

[0020] Axial direction is defined herein as a direction parallel to or along the longitudinal axis. The longitudinal axis may extend perpendicular to the main extension plane of the mounting section. In particular, the longitudinal axis may intersect the mounting section and / or extend through its center, e.g. the geometric center and / or its center of gravity. The longitudinal axis may intersect the front side and / or the rear side of the carrier at the mounting section and / or extend perpendicular thereto.

[0021] For example, when moving from the first position to the sensing position, the sensor is displaced along the axis by at least 0.5 cm or at least 1 cm. Additionally or alternatively, the sensor is displaced along the axis by up to 5 cm or up to 3 cm.

[0022] Here and in the following, the longitudinal axis is used in particular to define a coordinate system and / or to define directions in order to describe the relative positions and relative movements between elements or members or structures. As already mentioned, the direction parallel to the longitudinal axis is defined herein as axial. The directions perpendicular to and / or intersecting the longitudinal axis are referred to herein as radial. Radially inward is the radial direction pointing towards the longitudinal axis. Radially outward is the radial direction pointing away from the longitudinal axis.

[0023] The terms "angular direction", "azimuthal direction" and "rotational direction" are used synonymously herein. Such direction is perpendicular to the longitudinal axis and perpendicular to the radial direction. This direction is specifically the direction of motion on a circular track about the longitudinal axis.

[0024] In at least one embodiment, an electronic component for a drug delivery device includes a carrier having a mounting section and a sensor section connected to the mounting section via a connection region. A sensor is disposed on the sensor section and an electrical element is disposed on the mounting section, the electrical element being electrically connected to the sensor. The sensor section is movably disposed relative to the mounting section between a first position and a sensing position. In the sensing position, the sensor is offset along an axis compared to the first position.

[0025] The electronic components described herein can, among other things, be easily and reliably mounted to the mounting member. For example, the electronic component with the sensor section in a first position can be first placed on the mounting member and then the sensor section can be moved to its sensing position. In doing so, the sensor can be brought to a nominal position and coupled to the mounting member to hold it in the nominal position.

[0026] According to at least one embodiment, the distance between the connection region and the sensor is constant or substantially constant during movement of the sensor section from the first position to the sensing position, e.g., the distance changes by at most 5% or at most 1% during the movement.

[0027] According to at least one embodiment, the carrier is stiffer in the mounting section than in the connection region and / or sensor section, e.g., the carrier is at least twice as thick in the mounting section than in the connection region and / or sensor section.

[0028] According to at least one embodiment, besides the electric elements and the sensors, one or more further electric elements can be arranged on the carrier. The electric or electronic components can include one or more or all of the following further electric elements: a clock, a memory, a capacitor, an inductor, a processor, a control unit, a switch, a part of a Bluetooth module or more generally a wireless communication module, a further sensor, for example a pressure sensor or a touch sensor or a capacitive sensor.

[0029] One or more or all of the further electrical elements can be arranged on the same side of the carrier as the electrical elements arranged on the carrier, for example on the front side of the carrier. Additionally or alternatively, one or more or all of the further electrical elements can be arranged on the opposite side of the electrical elements (in particular on the same side as the sensor), for example on the back side. One or more or all of the further electrical elements can be arranged in the mounting section. For example, a further sensor, for example a pressure sensor or a touch sensor or a capacitive sensor, is arranged in the mounting section.

[0030] According to at least one embodiment, the electrical or electronic component includes an antenna. The antenna can be configured for wireless communication between the electronic component and a further device, such as a smartphone or a computer. For example, data received using a sensor can be transmitted to the further device via the antenna. The antenna can be electrically connected to the electrical element and / or the sensor.

[0031] The antenna may include an antenna section formed by the carrier. The antenna section may be connected to and / or adjacent to the mounting section and / or may extend away from the mounting section. In particular, the antenna section is elongated, i.e., the length of the antenna section is greater than the width and / or thickness of the antenna section. For example, the length is at least 5 times or at least 10 times the width. The antenna section may be formed to be flexible. In particular, the antenna section may be configured to be coiled, for example around a longitudinal axis, when the electronic component is attached to the drug delivery device.

[0032] According to at least one embodiment, the sensor is configured to detect a relative movement between the sensor and a further member, hereinafter also referred to as a movable member. In particular, the sensor is configured to detect a relative rotational movement between the sensor and the further member. For example, the sensor is configured to detect a rotational movement of the further member when the sensor overlaps or is aligned about an axis with the further member.

[0033] According to at least one embodiment, the sensor is arranged to measure or detect a sensing region. Preferably, in the sensing position, the sensing region is located axially below the mounting section. In particular, the sensing region radially overlaps the mounting section. For example, when viewed along the longitudinal axis, in particular in the distal direction, the sensing region is covered by the mounting section. The sensor can be configured to detect physical, electromagnetic, and / or chemical characteristics or changes occurring in the sensing region.

[0034] For example, the sensor includes a sensor surface configured to receive a signal from and / or abut against an object to be inspected. In the sensing position, the sensor surface preferably faces a sensing area located axially below the mounting section and / or faces an object to be inspected located axially below the mounting section. In particular, in the sensing position, the sensor surface may face the longitudinal axis. In the sensing position, a normal to the sensor surface may extend parallel to a main extension plane of the mounting section or at an acute angle of, for example, up to 10°. In particular, in the sensing position, the sensor surface may face radially inward.

[0035] According to at least one embodiment, the sensor is an optical sensor. As an optical sensor, the sensor preferably comprises a light-emitting element, for example an LED. The light-emitting element can emit radiation, for example infrared radiation, the reflected portion of which is then detected by the sensor, for example by its radiation-sensitive element, such as a detector chip.

[0036] Additionally or alternatively, the sensor may be a radiation sensor, such as a light or infrared sensor, or an accelerometer, or a sound sensor, or a pressure sensor, or a temperature sensor, or a proximity sensor, or an ultrasonic sensor, or a color sensor, or a humidity sensor, or a tilt sensor, or a flow sensor, or a magnetic sensor, such as a Hall effect sensor, or a lidar, or a current sensor, or an optical sensor, or a force / torque sensor, or a strain gauge sensor, or a mechanical switch. However, preferably, the sensor is not a mechanical switch. The sensor may be a digital sensor or an analog sensor.

[0037] According to at least one embodiment, in the first position and / or the sensing position, the sensor is angularly offset, i.e. offset in the angular direction, with respect to the connection area. In particular, the sensor does not overlap the connection area in the angular direction. For example, the sensor is angularly offset by at least 5° or at least 10° or at least 20° with respect to the connection area. Additionally or alternatively, the sensor may be angularly offset by up to 30° or up to 20° with respect to the connection area. In particular, the shortest path from the area of ​​the carrier where the sensor is located to the mounting section and / or the connection area is a path that does not pass entirely through the carrier, for example through the gap between the mounting section and the sensor section.

[0038] According to at least one embodiment, moving the sensor section from the first position to the sensing position includes axial and / or radial, e.g., radially inward, movement. For example, moving the sensor section from the first position to the sensing position is primarily radial and axial. During the movement, the axial and / or radial displacement may be larger than the angular displacement, e.g., at least 5 times or at least 10 times larger. For example, during the movement, the sensor is not moved angularly. This means that the angular position of the sensor and / or sensor section may be the same in the first position and in the sensing position, e.g., remains the same during the movement from the first position to the sensing position.

[0039] According to at least one embodiment, in the sensing position, the sensor is axially offset relative to the connection region. For example, the sensor is axially offset by at least 0.5 cm or at least 1 cm relative to the connection region. Additionally or alternatively, in the sensing position, the sensor may be axially offset by up to 5 cm or up to 3 cm relative to the connection region. In the first position, the sensor may be radially offset by, for example, the same distance relative to the connection region.

[0040] In the first position, the sensor can be axially overlapped or axially aligned with the connection region. Additionally or alternatively, in the first position, the sensor can be less axially offset with respect to the connection region than in the sensing position. For example, in the first position, the axial offset for the sensor compared to the connection region is up to 0.5 cm. In the sensing position, the sensor can be radially aligned or radially overlapped with the connection region.

[0041] Here and below, when discussing the relative position between two elements, this may in particular relate to the relative position between the geometric centers of the elements or between the centers of gravity of the elements. In the case of a sensor, the position may also be defined by the optical center of the sensor.

[0042] According to at least one embodiment, the sensor section includes a first subsection and a second subsection.

[0043] According to at least one embodiment, the first subsection connects the second subsection to the connection region. For example, the first subsection is connected to the second subsection via a further connection region. The first subsection can be directly adjacent to the second subsection and / or the connection region. Alternatively, a further subsection, for example a curved subsection, can be formed between the first and second subsections. The subsections can be positioned behind other subsections along the length of the sensor section and / or each can extend across the entire width of the sensor section.

[0044] The first subsection and / or the second subsection can be formed to be stiffer, e.g., thicker, than the further connection region and / or the connection region. The further connection region can be formed to be flexible or bendable such that the second subsection can be movable relative to the first subsection, e.g., pivotable and / or bendable relative to the first subsection.

[0045] According to at least one embodiment, in the first position and / or the sensing position, the second subsection is disposed angularly offset relative to the connection region and / or the first subsection. For example, in the first position, a gap is formed between the second subsection and the mounting section, such that there is no straight path completely through the carrier from the second subsection to the mounting section. In the sensing position, the gap can be disposed axially between the second subsection and the mounting section.

[0046] According to at least one embodiment, in the first position, the second subsection can be axially aligned or axially overlapping with the first subsection and / or the connection region, and in the first position, the second subsection is in particular radially offset with respect to the first subsection and / or the connection region.

[0047] According to at least one embodiment, in the sensing position, the second subsection is axially offset relative to the first subsection and / or the connection region, and in the sensing position, the second subsection can be radially aligned or radially overlapping with the first subsection and / or the connection region.

[0048] According to at least one embodiment, in the first position and / or the sensing position, the sensor angularly overlaps with the second subsection. The sensor can be arranged in the second subsection. A conductive track from the sensor to the electrical element can run from the sensor through the second subsection, through a further connection region and / or a curved subsection if available, through the first subsection, through the connection region to the mounting section.

[0049] According to at least one embodiment, in the first position and / or in the sensing position, the second subsection is oriented more angularly than the first subsection, in particular, a main extension axis of the second subsection may be oriented more angularly than a main extension axis of the first subsection.

[0050] For example, in the first position and / or sensing position, the angle between the main extension axis of the second subsection and the angular direction is at most 45° or at most 30° or at most 20°. In the first position and / or sensing position, the angle between the main extension axis of the first subsection and the angular direction may be at least 45° or at least 60° or at least 70°. For example, the angle of the main extension axis of the second subsection relative to the angular direction is at most 50% or at most 30% of the angle between the main extension axis of the first subsection and the angular direction.

[0051] According to at least one embodiment, in the first position, the first subsection is oriented more radially than the second subsection. In the sensing position, the first subsection can be oriented more axially than the second subsection. Thus, the angular values ​​mentioned in the previous paragraph can be applicable to radial and / or axial orientations.

[0052] Additionally or alternatively, in the first position and / or the sensing position, the second subsection can be oriented more along the axis of rotation than the first subsection, the axis about which the sensor section is folded / bent / pivoted relative to the mounting section when moved from the first position to the sensing position. For example, in the first position and / or the sensing position, the second subsection can extend parallel to the axis of rotation and / or the first subsection can extend perpendicular to the axis of rotation.

[0053] According to at least one embodiment, the sensor section is an arm of the carrier. The arm can have a free end. Further, the arm can extend between the connection region and the free end.

[0054] In particular, the arm may be elongate. The length of the arm may therefore be greater than the width and / or thickness of the arm. For example, the length of the arm is at least twice or at least five times the width and / or thickness of the arm. A free end of the arm may be movable relative to the attachment section. The free end of the arm may be a longitudinal end of the arm. The further longitudinal end of the arm may adjoin the connection region.

[0055] According to at least one embodiment, the orientation of the arms changes from the connection region towards the free end. This can be valid for the first position and / or the sensing position. For example, in the first position, the arms start from the connection region and first extend away from the mounting section, e.g. mainly or exclusively radially outward, then curve and from there to the free end, they extend less away from the mounting section, e.g. mainly or exclusively angularly. Thus, in the sensing position, the arms start from the connection region and first extend away from the mounting section, e.g. mainly or exclusively axially, in particular distally, then curve and from there to the free end, they extend less away from the mounting section, e.g. mainly or exclusively angularly.

[0056] According to at least one embodiment, in the first position and / or in the sensing position, the arm is more angularly oriented in a region closer to the free end than in a region closer to the connection region, e.g., in a region from the free end towards the bend of the arm, the arm is more angularly oriented than in a region from the bend towards the connection region.

[0057] According to at least one embodiment, the arms are in the shape of a dog's legs.

[0058] According to at least one embodiment, the sensor section is formed with a slit. The length of the slit is greater than the width of the slit, for example at least 5 times or at least 10 times the width. The slit can extend through the sensor section, i.e., from the front side to the back side and / or through the entire thickness of the sensor section.

[0059] According to at least one embodiment, the slit extends along the sensor section, in particular along the arm. For example, the slit follows the shape of the sensor section. The slit may change its orientation along its length. In particular, the slit comprises a first region and a second region, the first region being closer to the connection region. The second region may be closer to the free end of the arm. When the sensor section is in the first position and / or in the sensing position, the slit in the second region may be angularly oriented than that of the first region. In particular, the slit may be formed continuously. The slit may extend over a majority of the length of the sensor section, for example over at least 50% or at least 75% of the length of the sensor section.

[0060] According to at least one embodiment, the slit includes a hole at one longitudinal end or at both longitudinal ends. The diameter of the hole may be greater than the width of the slit in the central region. The hole may extend through the sensor section.

[0061] The slits formed in the sensor section provide a large mobility, particularly an axial mobility, of the sensor section when the sensor section is in its sensing position, which simplifies mounting of the electrical or electronic component to the mounting member and bringing the sensor to its nominal position relative to the mounting member.

[0062] According to at least one embodiment, in the first position and / or the sensing position, the sensor is angularly aligned with or overlaps the slit.

[0063] According to at least one embodiment, in the sensing position, the sensor is axially offset relative to the slit. For example, the sensor is axially positioned further from the mounting section than the slit when the sensor section is in the sensing position. In particular, in the sensing position, the sensor is axially offset relative to the slit than in the first position.

[0064] According to at least one embodiment, the conductive tracks of the carrier, for example the conductive tracks electrically connecting the sensor with the electrical element, extend next to and along the slits, for example the conductive tracks extend parallel to the slits.

[0065] According to at least one embodiment, the electronic component includes at least one coupling feature. The coupling feature can be configured to interact with one or more coupling features of the mounting member to hold the sensor in a nominal position relative to the mounting member. The coupling feature can be formed on or by one or more coupling areas of the sensor section. For example, in the first position and / or the sensing position, the coupling feature is located angularly offset relative to the sensor. The sensor can be located between the coupling features in an angular orientation. For example, one coupling feature is formed at or by a free end of an arm.

[0066] The coupling features may be regions of the sensor section configured to be inserted into one or more pockets of a coupling member. In those regions, the carrier may be thinner than in regions where the sensor is located, for example. The coupling features may be located on a second subsection of the sensor section.

[0067] According to at least one embodiment, the sensor is disposed on a tab of the sensor section. The tab may be angularly offset relative to the connection region and / or the first subsection. In the sensing position, the tab may extend axially away from the remainder of the sensor section away from the mounting section. For example, in the sensing position, the tab is axially located away from the mounting section than the remainder of the sensor section, e.g., away from the coupling feature and / or away from the curved subsection and / or away from the first subsection. The tab may be part of the second subsection.

[0068] According to at least one embodiment, the carrier includes a second sensor section. All configurations disclosed in relation to the sensor section are also disclosed in relation to the second sensor section. In particular, a second sensor can be arranged in the second sensor section, and the second sensor section can be connected to the mounting section via a connection region. The second sensor can be of the same type as the sensor of the sensor section. All configurations disclosed in relation to the sensor and the sensor section are also disclosed in relation to the second sensor and the second sensor section.

[0069] The second sensor can also be electrically connected to the electrical element on the mounting section. The second sensor section can also be movable, in particular pivotable or bendable, between a first position and a sensing position, such that in the sensing position the second sensor is axially offset compared to the first position. The second sensor can be configured to detect relative motion between the second sensor and the further member. Measurements from the sensor and the second sensor can be combined, for example, via a Gray code output generated by the combined sensor (i.e. the sensor and the second sensor) in response to motion of the further member, for example to increase the resolution of the measurement of motion and / or to determine the direction of motion of the further member relative to the sensor and the second sensor.

[0070] According to at least one embodiment, the second sensor section is angularly offset relative to the sensor section, which may be effective when both sensor sections are in their respective first positions and / or their respective sensing positions. For example, the two sensors may be angularly offset when both sensor sections are in their respective sensing positions.

[0071] The angular distance between the two sensors may be predetermined depending on the sensing function of the further member when the respective sensor section is in the sensing position, for example the two sensors are optical sensors.

[0072] According to at least one embodiment, the further member includes an encoder structure. The encoder structure can move, for example rotate, relative to the sensor, for example during a dose delivery operation performed by the drug delivery device. The movement of the encoder structure relative to the sensor can be detected and / or measured via the sensor, in particular so that the relative movement between the sensor and the further member can be quantified, for example a rotation angle can be determined. The measured value can be used to calculate the dose delivered during the dose delivery operation. The encoder structure can be provided on or by an outer surface of the further member, for example in a circumferential direction around the further member. The encoder structure can include circumferentially alternatingly arranged encoder regions exhibiting different reflectivities to light or infrared light. The encoder structure includes, for example, regions of alternating dark and light regions. The angular width of each of the encoder regions can be W, for example W=30°. Preferably, W is selected such that W*m=360°, where m is an integer. The angular spacing between two sensors can be W*n+W / 2, where n is an integer. The angular spacing between the two sensors refers in particular to the angular spacing between the optical centers of the two sensors. Thus, the sensors may be out of phase with respect to the encoder area while the further member rotates relative to the sensors.

[0073] According to at least one embodiment, the sensor and encoder structure are adjusted such that the sensor and further member provide a system suitable for generating a multi-bit Gray code output, for example a 2-bit Gray code, during movement of the further member relative to the sensor. Thus, a unique relative position between each sensor and the further member, for example four relative positions in the case of a 2-bit Gray code, can be determined via the combined output of each sensor.

[0074] According to at least one embodiment, in the first position and / or the sensing position, the connection region of the sensor section and the second sensor section is arranged between the sensor in an angular direction. The sensor section and the second sensor section can be oriented in opposite angular directions. For example, in the first position and / or the sensing position, the sensor section and the second sensor section are arranged with mirror symmetry with respect to a plane extending parallel to the axial and radial directions.

[0075] Next, a mounting member for an electrical or electronic component is shown. In particular, the mounting member can be configured to mount or hold the electrical or electronic components shown herein. The mounting member can be a chassis underside. For example, the mounting member is formed from plastic and / or to be one piece.

[0076] According to at least one embodiment, the mounting member includes an upper surface. The upper surface is particularly configured to allow the mounting section to be placed thereon. For example, the area and / or shape of the upper surface is adapted to the area and / or shape of the mounting section.

[0077] For example, the top surface has a circular shape. The top surface is configured, in particular, to hold or carry the mounting section. When the electronic component is mounted on the mounting member, the longitudinal axis can extend obliquely, for example vertically, through the top surface, for example through its center.

[0078] According to at least one embodiment, the mounting member includes a side surface. The side surface may extend at an angle, e.g., vertically, relative to the upper surface. The side surface may extend circumferentially around the longitudinal axis.

[0079] The attachment member may be elongate and / or tubular in shape, for example, the primary direction of extension of the attachment member extends along a longitudinal axis.

[0080] According to at least one embodiment, the side includes at least one interlocking feature for holding the sensor in a nominal position when the sensor section is in its sensing position.

[0081] According to at least one embodiment, at least one interlocking feature of the side surface is configured to prevent axial and / or rotational displacement of the sensor relative to the nominal position of the sensor. For example, the at least one interlocking feature is realized by one or more protrusions projecting radially outward. The protrusions may abut or be positioned to abut the sensor to block or limit rotational and / or axial movement of the sensor.

[0082] According to at least one embodiment, at least one coupling feature of the side surface is configured to prevent radial displacement of the sensor relative to its nominal position. For example, the at least one coupling feature is a pocket configured to receive a coupling feature of the electronic component, in particular to receive a free end of the arm. The pocket can be configured to receive the coupling feature of the electronic component by axially sliding the coupling feature of the electronic component, for example axially away from the mounting section. The lateral surface can include two such coupling features, for example in the form of a pocket each for receiving a coupling feature of the sensor section. In the nominal position, the sensor can be angularly arranged between those two coupling features of the side surface.

[0083] Next, an apparatus for a drug delivery device is shown.

[0084] According to at least one embodiment, the device includes an electronic component, which may be any electronic component illustrated herein.

[0085] According to at least one embodiment, the device includes an attachment member, which may be any attachment member shown herein.

[0086] All features disclosed in relation to the electronic components and / or mounting members are also disclosed in relation to the apparatus, and vice versa.

[0087] According to at least one embodiment, the electronic component is mounted to a mounting member, e.g., the mounting member carries the electronic component. The electronic component may be non-rotatably and / or axially and / or radially fixed to the mounting member.

[0088] According to at least one embodiment, the mounting section rests on the top surface. For example, the mounting section covers a majority of the top surface, for example at least 50% or at least 75%. The mounting section and / or elements disposed on the mounting section, for example electrical elements, can abut the top surface.

[0089] According to at least one embodiment, the sensor section is in its sensing position, for example, the sensor section is pivoted or bent or folded over an edge of the mounting member formed between the top surface and the side surface, and the bending axis of the carrier, about which the sensor section is bent or pivoted or folded relative to the mounting section, can extend parallel to said edge.

[0090] According to at least one embodiment, the sensor is held in its nominal position by at least one interlocking feature of the mounting member.

[0091] According to at least one embodiment, the device includes a movable member arranged to be movable relative to the sensor. For example, the movable member is coupled to the device. The movable member can be arranged to be movable relative to the sensor in a rotational and / or axial direction. The movable member can be a further member mentioned above.

[0092] The movable member may include a sensing surface configured to be inspected by the sensor. The sensing surface may face radially outward. The sensing surface may include or form the encoder structure referred to above. For example, the sensing surface in combination with the sensor and the second sensor as further discussed above may be suitable for defining a Gray code. The sensor of the sensor section or its sensor surface may face the sensing surface. The movable member may include an encoder ring and / or a dial setting sleeve.

[0093] According to at least one embodiment, the sensor is configured to detect movement, in particular rotational movement, of the movable member relative to the sensor.

[0094] According to at least one embodiment, in a first state of the device, the movable member can be non-rotatably locked to the sensor. This means that in the first state, the movable member cannot rotate relative to the sensor. For example, in the first state, the movable member is non-rotatably locked to the mounting member via a rotation lock interface. The rotation lock interface can be a toothed interface. The first state can be a state for dialing in a dose.

[0095] According to at least one embodiment, in a second state of the device, the movable member is rotatable relative to the sensor. In particular, a rotation lock interface between the movable member and the mounting member is released in the second state. The second state may be a state for dispensing a dialed dose.

[0096] Next, a drug delivery device is shown. The drug delivery device may be an injection device and / or a pen-type device, for example, a dial-extension pen. The drug delivery device may be a variable dose device that allows the user to variably set the dose of the drug to be delivered. For example, the drug delivery device is a reusable device.

[0097] According to at least one embodiment, a drug delivery device includes the electronic components as shown herein or the apparatus as shown herein, and therefore any configuration disclosed in relation to the electronic components or apparatus is also disclosed in relation to the drug delivery device and vice versa.

[0098] According to at least one embodiment, the drug delivery device includes a container holder for holding the drug container. The container holder may be the housing of the drug delivery device or may be connected or connectable to the housing. The container holder may be configured to hold the drug container axially and / or non-rotatably fixed relative to the housing of the drug delivery device. In particular, the container holder may hold the drug container such that the drug container does not move axially and / or rotationally during the drug delivery process.

[0099] According to at least one embodiment, the drug delivery device includes a drug container filled with a drug. The drug container may be a syringe with a pre-attached needle at its distal end. Alternatively, a needle may be attachable to the drug container, for example at its distal end.

[0100] The drug delivery device may be elongate. The main direction of extension of the drug delivery device may coincide with the longitudinal axis. Additionally or alternatively, the drug delivery device may be rotationally symmetrical with respect to the longitudinal axis. The direction parallel to the longitudinal axis is referred to herein as the axial direction. In one example, the drug delivery device is cylindrical.

[0101] Further, the drug delivery device may include an end, e.g., a longitudinal end, which may be provided to face or press against a skin area of ​​a human body. The end is referred to herein as the distal end. A drug or agent may be delivered through the distal end. The opposite end is referred to herein as the proximal end. The proximal end is away from the skin area during use. The axial direction from the proximal end to the distal end is referred to herein as the distal direction. The axial direction from the distal end to the proximal end is referred to herein as the proximal direction. The distal end of a member or element or configuration of a drug delivery device, e.g., a user interface member, is understood herein to be the end of the most distally located member / element / configuration. Thus, the proximal end of a member or element or configuration is understood herein to be the end of the most proximally located element / member / configuration.

[0102] In other words, distal is used herein to indicate a direction, end, or surface that is or will be positioned to face or point towards the dosing end of the drug delivery device or a component thereof and / or away from the proximal end of the drug delivery device or a component thereof. Meanwhile, proximal is used herein to indicate a direction, end, or surface that is or will be positioned to face or point away from the dosing end and / or the distal end of the drug delivery device or a component thereof. The distal end may be the end closest to the dosing end and / or the end furthest from the proximal end, and the proximal end may be the end furthest from the dosing end. The proximal surface may be the surface that faces away from the distal end and / or the proximal end, and the distal surface may be the surface that faces the distal end and / or away from the proximal end. The dosing end may be, for example, the needle end where the needle unit is or will be attached to the device.

[0103] According to at least one embodiment, the drug delivery device includes a user interface member, e.g., a knob. The user interface member can be configured for dialing a dose and / or for injecting a dose. The attachment member and / or the electronic component can be non-rotatably and / or axially fixed to the user interface member. The user interface member can be rotatably and / or axially movably arranged relative to the housing of the drug delivery device and / or relative to the drug container (holder).

[0104] For example, the drug delivery device can be used as follows: First, the user interface member is rotated relative to the housing and / or the drug container (holder). The user interface member can rotate on a helical path relative to the housing and / or the drug container (holder). Meanwhile, the device is in a first state in which the attachment member is locked non-rotatably with the movable member. Thus, the movable member rotates with the user interface member. After dialing in the dose, the user can press the user interface member to move it distally and deliver the dialed dose. The device can now be in or switch to a second state in which the attachment member is rotatably decoupled from the movable member. While the user interface member moves distally, the user interface member cannot rotate and the movable member can rotate. In doing so, the dialed dose can be ejected, e.g. injected into the patient. A sensor on the sensor section can measure the rotation of the movable member. Then, the measurement signals of the sensor can be transmitted to an electrical or electronic component, e.g. a processor, where the delivered dose can be determined from those measurement signals. That information can then be communicated to a further device, for example by a wireless communication module.

[0105] Next, a method for assembling an apparatus for a drug delivery device is presented. The method can be used to assembling the apparatus shown herein. Thus, all features disclosed in relation to the apparatus are also disclosed in relation to the method and vice versa.

[0106] According to at least one embodiment, the method includes a step in which an electronic component is provided, with the sensor section preferably in its first position.

[0107] According to at least one embodiment, the method includes the step of providing a mounting member.

[0108] According to at least one embodiment, the method includes placing the electronic component such that the mounting section is on the top surface, particularly such that the mounting section is resting on, e.g., contacting, the top surface.

[0109] According to at least one embodiment, the method includes a step in which the sensor section is moved to its sensing position, in which the sensor section may pivot or bend or fold at an edge formed between the top surface and the side surface.

[0110] According to at least one embodiment, when the sensor section is moved to its sensing position, the sensor section and / or sensor can be coupled to a side surface by one or more coupling features on the side surface.

[0111] Hereinafter, the electrical or electronic components, mounting members, apparatus, drug delivery devices, and methods for assembling the apparatus described herein will be described in more detail with reference to the drawings based on exemplary embodiments. In the individual figures, the same reference signs indicate the same or similar elements or elements that act in a similar manner. However, the size ratios are not necessarily to scale, rather individual elements may be shown in exaggerated size for better understanding. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0113] Exemplary embodiments are described below with reference to an insulin injection device, although the disclosure is not limited to such applications and may be similarly employed with injection devices configured to deliver other medicaments, or with drug delivery devices in general, preferably pen-type and / or injection devices.

[0114] Certain exemplary embodiments herein are shown for a drug delivery device in the form of an injection device, in which the user interface member is formed as a knob that simultaneously realizes an injection button and a dose setting (dial setting) member, for example similar to the device described in WO2014033195. The knob can therefore be used to initiate and / or perform a dose delivery operation of the drug delivery device, and can also be used to initiate and / or perform a dose setting operation. The device may be of the type in which the dial extends, i.e. its length increases during dose setting. Other injection devices with the same kinematic behavior of the dial extending during the dose setting and dose ejection operating modes are known, for example, as the Kwikpen® or Savvio® devices sold by Eli Lilly, and the FlexPen®, FlexTouch® or Novopen® devices sold by Novo Nordisk. The application of the general principle to those devices is therefore believed to be straightforward and will not be further described. However, in the present disclosure, the general principle is not limited to its kinematic behavior.

[0115] Certain other embodiments can be envisaged for application to injection devices with separate injection button and grip component / dose setting member, for example the device described in WO2004078239. The present disclosure therefore also relates to a system having two separate user interface members, for example a member for a dose setting operation and a member for a dose delivery operation. To switch between the dose setting and dose delivery configurations of the device, the user interface member for dose delivery can move relative to the user interface member for dose setting.

[0116] If one user interface member is provided, it can be moved distally relative to the housing. During each movement, a clutch connection between two members, the dose setting member and the drive mechanism member of the device, changes its state, for example, from an engaged state to a disengaged state or vice versa. When the clutch connection (formed, for example, by a set of interlocking teeth on the two members) is engaged, a rotation lock interface is established and the two members can be locked against rotation with respect to each other. When the clutch connection is disengaged or released, the rotation lock interface is released and one of the members can be rotatable relative to the other of the two members. One of the members can be a drive member or drive sleeve that engages with a piston rod of the dose setting and drive mechanism. The drive sleeve can be designed to rotate relative to the housing during dose setting and can be locked against rotation relative to the housing during dose delivery. The engagement between the drive sleeve and the piston rod can be a threaded engagement. Thus, axial movement of the drive sleeve relative to the housing rotates the piston rod, since the drive sleeve cannot rotate during dose delivery. This rotation can be translated into axial displacement of the piston rod during the delivery movement by a threaded connection between the piston rod and the housing.

[0117] 1 is an exploded view of an exemplary embodiment of a drug delivery device 1000. In this exemplary embodiment, the drug delivery device 1000 is an injection device, for example, a pen-type injector.

[0118] The injection device 1000 of FIG. 1 is an injection pen, which includes a housing 10 for holding a drug container 14, e.g. an insulin container, or a container holder for such a container 14. The container 14 can contain a drug, e.g. insulin. The container 14 can be a cartridge or a receptacle for a cartridge, which can contain or be configured to receive a cartridge. A needle 15 can be attached to the container 14 or receptacle. The container 14 can be a cartridge, and the receptacle can be a cartridge holder. The needle 15 is protected by an inner needle cap 16 and an outer needle cap 17 or another cap 18. The insulin dose to be delivered from the injection device 1000 can be set, programmed or "dialed" by turning a user interface member 71 in the form of a knob 71, and the currently programmed or set dose is then displayed via a dosage window 13, e.g. in multiples of units. The units can be determined by a dose setting mechanism that allows the knob 71 to be rotated relative to the housing 10 only in integer multiples of one unit setting increments that can define one increment of the dosage. This can be achieved, for example, by a suitable ratchet system. The indicia displayed in the window can be presented on the number sleeve or on the dial setting sleeve 70. For example, if the injection device 100 is configured to administer human insulin, the dosage can be displayed in so-called international units (IU), where 1 IU is the biological equivalent of about 45.5 micrograms (1 / 22 mg) of pure crystalline insulin. Other units can be employed for injection devices for delivering analog insulin or other medications. It is noted that the selected dose can be displayed similarly, differently from that shown in the dosage window 13 of FIG. 1.

[0119] The dose window 13 may be in the form of an aperture in the housing 10 allowing the user to view a limited portion of the dial setting sleeve 70 that is configured to move when the knob 71 is turned to provide a visual indication of the dose currently programmed. The knob 71 rotates in a helical path relative to the housing 10 as it is turned during programming.

[0120] In this exemplary embodiment, knob 71 includes one or more features 71a, 71b, 71c in the form of a formation to facilitate grasping and / or attachment of a data collection device or electronic system.

[0121] The injection device 1000 can be configured such that turning the knob 71 produces a mechanical clicking sound to provide audio feedback to the user. In this embodiment, the knob 71 also serves as an injection button. When the needle 15 is inserted into the patient's skin portion and the knob 71 is then pressed axially, the insulin dose displayed in the display window 13 is ejected from the injection device 1000. When the needle 15 of the injection device 1000 remains in the skin portion for a certain period of time after the knob 71 is firmly pressed, the dose is injected into the patient's body. The ejection of the insulin dose can also produce a mechanical clicking sound, but the sound is different from the sound produced when rotating the knob 71 during the dialing of the dose.

[0122] In this exemplary embodiment, during delivery of an insulin dose, the knob 71 is returned to its initial position with an axial movement without rotation, and the dial setting sleeve 70 or number sleeve 70 is rotated to return to its initial position, e.g., to indicate a dose of zero units. As already mentioned, the present disclosure is not limited to insulin, but should encompass all drugs within the drug container 14, particularly liquid drugs or drug formulations.

[0123] The injection device 1000 can be used for several injection processes until the insulin container 14 is empty or the expiration date of the medication in the injection device 1000 is reached (e.g., 28 days after first use).

[0124] Furthermore, before using the injection device 1000 for the first time, it may be necessary to perform a so-called "priming shot" to ensure that fluid flows correctly from the insulin container 14 and needle 15, for example by selecting 2 units of insulin and pressing knob 1 while holding the injection device 1 with needle 15 pointing upwards. For ease of explanation, it is assumed below that the ejected amount substantially corresponds to the dose to be injected, so that, for example, the amount of drug ejected from the injection device 1000 is equal to the dose the user will receive.

[0125] As explained above, the knob 71 also functions as an injection button, so that the same component is used to dial / set the dose and to dispense / deliver the dose. Here again, we note that a configuration with two different user interface members, preferably only movable relative to each other in a limited way, is also possible. However, in the following, we focus on a single user interface member providing the functions of dose setting and dose delivery. In other words, the setting surface of the member that is touched by the user for the dose setting operation and the dose delivery surface that is touched by the user for the dose delivery operation are immovably connected. Alternatively, they may be movable relative to each other if different user interface members are used. The user interface members are preferably moved relative to the body or housing of the device during the respective operations. During dose setting, the user interface member is moved proximally and / or rotated relative to the housing. During dose delivery, the user interface member moves axially, e.g. distally, preferably without rotating relative to the housing or body.

[0126] 1 also shows the coordinate system used herein for identifying the position of a member or element or configuration. The distal direction D and the proximal direction P run parallel to the longitudinal axis L. The longitudinal axis L is or coincides with the main axis of extension of the device 1000. The radial direction R is perpendicular to and intersects the longitudinal axis L. The azimuth direction C, also called the angular or rotational direction, is perpendicular to the radial direction R and the longitudinal axis L. To improve the clarity of the figures, the various directions and axes are not shown in all of the following figures.

[0127] 2 shows an exemplary embodiment of an electrical component 1 in a front view of the front side of a carrier 2 of the electronic component 1. The carrier 2 is a printed circuit board, or PCB for short. In particular, the carrier 2 is a so-called flexible board.

[0128] The carrier 2 comprises various sections. The mounting section 21 has an approximately circular shape. A longitudinal axis L (indicated by a cross) runs through the mounting section 21 perpendicular to the main extension plane of the mounting section 21 and / or perpendicular to the front side of the carrier 2 of the mounting section 21. In the mounting section 21, on the front side of the carrier 2, an electrical element 4 is arranged, for example a control unit or a processor or a real-time clock. Furthermore, one or more further electrical elements are arranged in the mounting section 21, for example on the front and / or rear side, such as capacitors, inductors and / or light-emitting diodes.

[0129] The two sensor sections 22, 22a are connected to the mounting section 21 via connection regions 23, 23a. Each of the sensor sections 22, 22a is movable, in particular bendable, relative to the mounting section 21 between a first position and a sensing position. Figure 2 shows the sensor sections 22, 22a in their respective first positions. In this first position, the main extension planes of the sensor sections 22, 22a extend parallel or approximately parallel to the main extension plane of the mounting section 21.

[0130] 2 also shows a flexion axis B about which the sensor sections 22, 22a can pivot or flex relative to the mounting section 21. In particular, the flexion axis B extends through each of the connection regions 23, 23a.

[0131] 2, the sensor section 22, 22a is an elongate arm of the carrier 2, one end of which is connected to the mounting section 21 via a connection region 23, 23a and the other end of which is a free end 226. A region of the arm adjacent the free end 226 forms a linking feature 225, which will be described in more detail below.

[0132] In the following, one of the sensor sections 22, also referred to as the first sensor section 22, will be described in more detail, although the configurations described with respect to the first sensor section 22 may be valid for the second sensor section 22a as well.

[0133] The arms are formed such that their orientation changes from the connection region 23 towards the free end 226. In particular, starting from the connection region 23, the arms are first formed by a first subsection 221 extending mainly in the radial direction R, then the arms 22 are formed by a curved subsection, then followed by a second subsection 222, in which the arms are oriented more in an angular direction C than in the radial direction R compared to the first subsection 221. The shape of the arms can be said to be that of a dog's leg.

[0134] The sensor section 22 also includes a tab 223 that projects from the remainder of the arm away from the mounting section 21. The tab 223 provides a mounting area for a sensor 3, as described below. The tab 223 is angularly offset relative to the connection area 23 of the sensor section 22.

[0135] 2, the angular orientation of the first sensor section 22 is opposite to the angular orientation of the second sensor section 22a. In particular, the sensor sections 22, 22a are arranged with mirror symmetry with respect to a radially extending axis.

[0136] 2 also shows that the sensor section 22 is formed with slits 224. The slits 224 are elongated and also vary along their length. In particular, the slits 224 follow the shape of the sensor sections 22, 22a. At their longitudinal ends, the slits 224 are hole-shaped with a larger diameter than the center of the slits 224.

[0137] The electrical component 1 also includes an antenna 5. The antenna 5 comprises an antenna section of the carrier 2, which is elongated and connected to the mounting section 21. Starting from the mounting section 21, the antenna section extends first in a radial direction and then in a direction perpendicular to the radial direction. The antenna section can be configured to be wrapped around the longitudinal axis L when assembled into the drug delivery device.

[0138] The carrier 2 also includes a further mounting section 21a of similar shape to the mounting section 21. The further mounting section 21a and the mounting section 21 are connected via an elongated connecting section 21b of the carrier 2. The carrier 2 may be flexible or bendable at its connecting section 21b, so that the further mounting section 21a can be moved to a position where the further mounting section 21a is arranged above the mounting section 21 and axially offset with respect to the mounting section 21. A battery for powering electrical elements on the carrier 2 can then be arranged axially between the mounting section 21 and the further mounting section 21a, and the battery can be electrically connected to the mounting section 21 as well as to the further mounting section 21a.

[0139] FIG. 3 shows the electrical components of FIG. 2, but now turned over so that the rear side of the carrier 2 can be seen. A sensor 3, 3a is mounted on a tab 223 of the sensor section 22, 22a. The sensor 3, 3a is angularly offset with respect to the connection area 23, 23a. The sensor 3, 3a can be electrically connected to an electrical element 4 on the front side of the carrier 2. For example, a conductive track extends from the sensor 3 along the sensor section 22, 22a through the connection area 23, 23a to the electrical element 4, electrically connecting the electrical element 4 with the sensor 3, 3a. The sensor 3, 3a can be, for example, an optical sensor for detecting light or infrared radiation reflected from a surface. A radiation source, for example an LED, for generating light or radiation can be incorporated into the sensor, which in addition to the radiation source can include a detector chip for receiving the reflected radiation.

[0140] 4 shows in a perspective view a section of the electrical component 1, for example the electrical component 1 of FIGS. 2 and 3. The illustrated sensor section 22 is now in its sensing position. The carrier 2 is shown to be formed with a smaller thickness in a first lower section 221 adjacent the mounting section 21 or the connection region 23 than the mounting section 21. This allows the sensor section 22 to be bent from a first position relative to the mounting section 21 into its sensing position.

[0141] As can further be seen in FIG. 4, the sensor section 22 is formed to be thicker at the tab 223 than in the area of ​​the second subsection 222 that forms the free end 226 and also forms the interlocking feature 225 .

[0142] 4 also shows that between the second subsection 222 and the first subsection 221, in particular between the curved subsection 227 and the second subsection 222, a further connection region 23b is formed, which region 23b is flexible so that the second subsection 222 can move or bend or pivot relative to the first subsection 221 about a further bending axis B2. In particular, this allows the sensor 3 to be moved radially. The carrier 2 is formed such that in the further connection region 23b it is also thinner than the mounting section 21 or the tab 223.

[0143] 5 shows the mobility of the sensor section 22 relative to the mounting section 21 when the sensor section 22 is in the sensing position. This mobility allows the precise position of the sensor 3 to be adjusted. In particular, the special shape of the sensor section 22, with its reorientation and the presence of the slits 224, allows the sensor position to be adjusted axially, angularly, radially, and also allows the sensor to rotate about the radial axis of rotation.

[0144] 6 shows the electrical component 1, for example the electrical component of the exemplary embodiment described above, with the sensor section 22 in the sensing position. To better visualize the position of the sensor 3, 3a, the carrier 2 is depicted as transparent in the area of ​​the sensor 3. The sensor 3, 3a is arranged to measure a sensing area located axially below the mounting section 21. The sensor surface of the sensor 3, 3a preferably faces radially inwards towards its sensing area and the longitudinal axis L.

[0145] The movable member 8 is arranged in the sensing area, i.e. axially below the mounting section 21, in axial overlap or alignment with the sensor 3, 3a. In particular, the axial overlap of the movable member 8 with the sensor 3, 3a may comprise surface structures and / or areas of alternating reflective and low reflective areas, for example areas of alternating dark and light areas or areas of alternating recessed and non-recessed areas. The sensor 3, 3a may be an optical sensor for detecting radiation reflected from the further member and for transmitting an associated measurement signal to the electrical component 4 or to the processor. If the area reflects more radiation to the sensor, for example because it is closer to the associated sensor and / or has a higher reflectivity, the measurement signal will be higher than if the area reflects less radiation to the sensor, for example because it is further away from the associated sensor and / or has a lower reflectivity. The movable member 8 is in particular rotatable with respect to the sensor 3. The movable member 8 may be or include a dial setting sleeve and / or an encoder ring. The movable member may move, e.g. rotate, relative to the sensor during a dose delivery operation, e.g. only during a dose delivery operation. The sensor and the movable member may move together, e.g. rotatably and / or axially, relative to the housing of the drug delivery device during a dose setting operation.

[0146] 7 shows a proximal section of an exemplary embodiment of a drug delivery device 1000. In particular, the area of ​​the proximal user interface member 71 is shown. FIG. 7 is a cross-sectional view of the proximal section of the drug delivery device 1000 of, for example, FIG. 1. As can be seen, the electrical component 1 is mounted to a mounting member 100. The mounting member 100 is a chassis lower portion including a top surface 101 and a side surface 102. The mounting section 21 is mounted to the top surface 101 and the sensor section 22 is in its sensing position such that the sensor section 22 overlaps the side surface 102 about an axis.

[0147] It is further shown that a further mounting section 21a is arranged axially offset relative to the mounting section 21, with the battery 6 being arranged axially between the mounting section 21 and the further mounting section 21a.

[0148] The drug delivery device 1000 shown in FIG. 7 also includes a movable member 8, such as the movable member 8 of FIG.

[0149] Figure 8 is a view on the section indicated by the horizontal dashed line in figure 7. The sensors 3, 3a are angularly offset from each other. The sensors 3, 3a are each configured to emit infrared radiation, which is reflected from the movable member 8 and then detected by the sensors 3, 3a. This makes it possible to detect the rotation of the movable member relative to the sensors 3, 3a.

[0150] In the exemplary embodiment of Figs. 7 and 8, the movable member 8 includes 12 alternating black and white regions around the movable member 8. Each region is 30° wide, which creates 12 transition edges per revolution. The angular spacing between the optical centers of the two optical sensors 3, 3a is 135°. With such an arrangement, one sensor 3 is placed 90° out of phase with the other sensor 3a (30n°+15° achieves this for any n). This facilitates the implementation of a quadrature encoder, i.e., the two sensors 3, 3a can be used in combination to determine the direction of rotation. Each transition of an edge past one or the other sensor (which occurs 24 times during one complete revolution of the movable member) represents one unit of drug dosing. Since each sensor is out of phase with respect to the surface structure region (having regions of higher or lower reflectivity) and the angular width of the region of the further member is appropriately selected, each combined sensor produces a Gray code output, for example a 2-bit Gray code output. This makes it possible to distinguish four different relative positions between each sensor and the member 8 .

[0151] In the case of optical sensors, depending on the last dispensed dose, each sensor 3, 3a can also point to either the black or white area of ​​the movable member 8. Nominally, the center of each sensor 3, 3a is located at an angle away from the transition edge between the black and white areas. The response of the sensor while pointing to the white area can be defined as a binary 1 and while pointing to the black area as a binary 0. The configuration in which the sensor 3, 3a nominally points to one of two states and transitions occur between those states is applicable to other sensor technologies as listed above.

[0152] During operation of the device 1000, the movable member 8 can move axially (i.e., proximally or distally) relative to the sensor 3, 3a (or vice versa). The sensor 3, 3a is positioned to view the movable member 8 radially such that the sensing distance remains relatively constant regardless of axial movement. Such an arrangement virtually eliminates "lens" action, i.e., objects moving in and out of the focus of the sensor. However, tolerance build-up due to natural part-to-part variations and variations due to the assembly process (e.g., solder thickness between the sensor and the PCB) means that radial and axial movements can be significant to the optimal operating range of the sensor. It is therefore desirable to minimize those tolerances as much as possible. This is achieved, among other things, by the special design of the electronic component 1 described herein.

[0153] Figure 9 shows a side view of an exemplary embodiment of the device. Figure 10 shows a perspective view of the device highlighting some details. In Figure 10, the carrier 2 has been made transparent to better view the position of the sensor 3.

[0154] The electrical component 1 is mounted on the mounting member 100, with the sensor section 22 in its sensing position. The lateral surface 102 of the mounting member 100 includes several coupling features 125a, 125b, 125c. Two of those coupling features 125a are pockets in which the coupling features 225 of the sensor section 22 are received. For example, the regions of the sensor section 22 located on either side of the sensor 3 in the angular orientation constitute the coupling features 225 that are slid into the pockets 125a in the distal direction D. Each pocket may be open proximally and closed distally. The coupling of the sensor section 22 to the mounting member 100 via the pockets 125a limits the displacement of the sensor 3 from its nominal position in the radial direction, preferably also in the distal direction D. Alternatively or additionally, one or more of the distal stop features 125d may comprise, for example, a radial protrusion to limit or prevent distal displacement of the sensor 3 relative to the mounting member 100. Each distal stop feature 125d is conveniently positioned to angularly and / or radially overlap a sensor 3.

[0155] Further limitation of radially inward movement can be achieved by a surface area of ​​the lateral surface 102 arranged radially inward with respect to the sensor section 22, which surface area is in radial abutment or configured to be in radial abutment with a region of the sensor section 22 located axially above the sensor 3. Alternatively or additionally, the sensor 3 itself can abut the mounting member 100 and / or its surface 102. This can prevent or help prevent radially inward movement of the sensor 3 relative to the mounting member 100. The sensing surface of the sensor 3 can be exposed and not covered by the surface 102, especially radially inward (e.g. because of an aperture in the surface), allowing the sensor to emit radiation to and / or receive radiation reflected therefrom via the sensing surface of the sensor 3 to the movable member.

[0156] A further connecting feature of the lateral surface 102 is a protrusion 125b, which protrudes radially outwardly and is configured to limit the movement of the sensor 3 in the axial direction, in particular in the proximal direction P. When in its nominal position, the sensor 3 is located downstream of the protrusion 125b in the distal direction D. The protrusion 125b is configured to abut the sensor 3 when the sensor 3 is moved in the proximal direction P from its nominal position.

[0157] Further interlocking features 125c are further protrusions projecting radially outwardly, which axially overlap and are arranged on either side of and angularly offset relative to the sensor 3. The protrusions 125c are configured to abut against the sensor 3 when the sensor 3 is angularly moved from its nominal position.

[0158] The terms "drug" or "medicament" are used interchangeably herein to describe a pharmaceutical formulation containing one or more active pharmaceutical ingredients or their pharma- ceutically acceptable salts or solvates, and optionally a pharma- ceutically acceptable carrier. An active pharmaceutical ingredient ("API"), in its broadest sense, is a chemical structure that has a biological effect on humans or animals. In pharmacology, drugs or medicines are used to treat, cure, prevent, or diagnose diseases or otherwise improve physical or mental well-being. Drugs or medicines can be used for a limited duration or periodically for chronic disorders.

[0159] As described below, drugs or agents may include at least one API or combinations thereof in various types of formulations for the treatment of one or more diseases. Examples of APIs may include small molecules with molecular weights of 500 Da or less, polypeptides, peptides, and proteins (e.g., hormones, growth factors, antibodies, antibody fragments, and enzymes), carbohydrates and polysaccharides, as well as nucleic acids, double-stranded or single-stranded DNA (including naked and cDNA), RNA, antisense nucleic acids such as antisense DNA and RNA, small interfering RNA (siRNA), ribozymes, genes, and oligonucleotides. Nucleic acids may be incorporated into molecular delivery systems such as vectors, plasmids, or liposomes. Mixtures of one or more drugs are also contemplated.

[0160] The drug or agent can be contained in a primary package or "drug container" adapted for use in a drug delivery device. The drug container can be, for example, a cartridge, syringe, reservoir, or other rigid or flexible vessel configured to provide a chamber suitable for storage (e.g., short-term or long-term storage) of one or more drugs. For example, in some cases, the chamber can be designed to store the drug for at least one day (e.g., from one day to at least 30 days). In some cases, the chamber can be designed to store the drug for about one month to about two years. Storage can be at room temperature (e.g., about 20° C.) or at refrigerated temperatures (e.g., from about −4° C. to about 4° C.). In some cases, the drug container can be or include a dual-chamber cartridge configured to separately store two or more components of a pharmaceutical formulation to be administered (e.g., an API and a diluent, or two different drugs), one in each chamber. In such cases, the two chambers of the dual-chamber cartridge can be configured to allow mixing between two or more components prior to and / or during administration to the human or animal body. For example, the two chambers can be configured to be in fluid communication with each other (e.g., via a conduit between the two chambers) and to allow mixing of the two components by a user, if desired, prior to administration. Alternatively or additionally, the two chambers can be configured to allow mixing upon administration of the components to the human or animal body.

An example of a hyaluronic acid derivative is Hylan G-F20 (Synvisc®), sodium hyaluronate.

[0170] The term "antibody" as used herein refers to an immunoglobulin molecule or an antigen-binding portion thereof. Examples of antigen-binding portions of an immunoglobulin molecule include F(ab) and F(ab')2 fragments that retain the ability to bind to an antigen. An antibody can be a polyclonal antibody, a monoclonal antibody, a recombinant antibody, a chimeric antibody, a deimmunized or humanized antibody, a fully human antibody, a non-human (e.g., murine) antibody, or a single chain antibody. In some embodiments, an antibody has effector function and is capable of fixing complement. In some embodiments, an antibody has reduced or no binding ability to Fc receptors. For example, an antibody can be an isotype or subtype, an antibody fragment, or a mutant that does not support binding to Fc receptors, e.g., with a mutation or deletion of the Fc receptor binding region. The term antibody also includes antigen-binding molecules based on tetravalent bispecific tandem immunoglobulins (TBTI) and / or dual variable region antibody-like binding proteins (CODV) with crossover binding region orientation.

[0171] The term "fragment" or "antibody fragment" refers to a polypeptide (e.g., antibody heavy and / or light chain polypeptide) derived from an antibody polypeptide molecule that does not include the full-length antibody polypeptide but comprises at least a portion of the full-length antibody polypeptide that is still capable of binding to an antigen. An antibody fragment can include truncated portions of a full-length antibody polypeptide, but the term is not limited to such truncated fragments. Antibody fragments useful in the present invention include, for example, Fab fragments, F(ab')2 fragments, scFv (single-chain Fv) fragments, linear antibodies, monospecific or multispecific antibody fragments, such as bispecific, trispecific, tetraspecific and multispecific antibodies (e.g., diabodies, triabodies, tetrabodies), monovalent or multivalent antibody fragments, such as bivalent, trivalent, tetravalent and multivalent antibodies, minibodies, chelating recombinant antibodies, tribodies or bibodies, intrabodies, nanobodies, small modular immunopharmaceuticals (SMIPs), binding domain immunoglobulin fusion proteins, camelized antibodies, and VHH-containing antibodies. Additional examples of antigen-binding antibody fragments are known in the art.

[0172] The term "complementarity determining region" or "CDR" refers to short polypeptide sequences in the variable regions of both heavy and light chain polypeptides that are primarily responsible for mediating specific antigen recognition. The term "framework region" refers to amino acid sequences in the variable regions of both heavy and light chain polypeptides that are not CDR sequences and are primarily responsible for maintaining the proper arrangement of the CDR sequences to allow antigen binding. Although the framework region itself typically does not directly participate in antigen binding, as is known in the art, certain residues in the framework region of a particular antibody may be directly involved in antigen binding or may affect the ability of one or more amino acids in the CDR to interact with the antigen.

[0173] Exemplary antibodies are anti-PCSK-9 mAb (eg, alirocumab), anti-IL-6 mAb (eg, sarilumab), and anti-IL-4 mAb (eg, dupilumab).

[0174] Pharmaceutically acceptable salts of any of the APIs described herein are contemplated for use in the drug or medicament in the drug delivery device. Pharmaceutically acceptable salts include, for example, acid addition salts and base salts.

[0176] Exemplary drug delivery devices can include needle-based injection systems as described in Table 1 of Section 5.2 of ISO11608-1:2014(E). As described in ISO11608-1:2014(E), needle-based injection systems can be broadly classified into multi-dose container systems and single-dose (partial or full discharge) container systems. The container can be a replaceable container or a non-replaceable one-piece container.

[0177] As further described in ISO11608-1:2014(E), a multi-dose container system can include a needle-based injection device with a replaceable container. In such a system, each container holds multiple doses and the size can be fixed or variable (pre-set by the user). Another multi-dose container system can include a needle-based injection device with a non-replaceable integral container. In such a system, each container holds multiple doses and the size can be fixed or variable (pre-set by the user).

[0178] As further described in ISO11608-1:2014(E), the single-dose container system can include a needle-based injection device with a replaceable container. In one example of such a system, each container holds a single dose, and in so doing, the entire deliverable volume is expelled (full expelled). In a further example, each container holds a single dose, and in so doing, a portion of the deliverable volume is expelled (partial expelled). Also as described in ISO11608-1:2014(E), the single-dose container system can include a needle-based injection device with a non-replaceable integral container. In one example of such a system, each container holds a single dose, and in so doing, the entire deliverable volume is expelled (full expelled).
