Definitions
- the present invention relates to the field of medical injection devices for administering liquid substances, in particular medicaments or medical substances such as insulin and hormone preparations.
- the invention relates to a portable electronic add-on module to be placed on a medical injection device.
- Different infusion and injection devices can support patients with a controlled subcutaneous or intramuscular administration of a dose of a medicament from a container. While in infusion systems a cannula remains in the patient's body for a long time, injection devices are removed from the injection site after each delivery.
- the container for example a pre-filled syringe
- the container for example a carpule
- An automatic injection device has a motor or a tensioned spring as an energy source to drive a piston rod and to move a piston in the reservoir, while in the case of a manual injection device, the piston rod is moved directly by a force of the patient.
- Diabetes is often treated by delivering insulin using an injection device in the form of an insulin pen with an adjustable dose.
- the pen has an elongated housing with a distal end for receiving a cannula or hollow needle and with a proximal end facing away from the injection site.
- An insulin pen can be operated as a disposable or reusable pen, automatically or manually.
- the insulin dose to be delivered is normally set by turning a dose knob and at the same time checking a dose indicator on the insulin pen.
- EP 3572107 A1 shows an additional electronic module which can be placed on the side of an injection device and fastened or clamped to it by means of a snap connection.
- a snap mechanism comprises two elastic wings on the additional module which define a receiving area for the injection device.
- the additional module comprises a sensor for detecting a state of the injection device and / or for monitoring an ongoing dispensing process.
- WO 2007/107564 A1 describes an additional module for an injection device with a dose setting button arranged at the proximal end of the injection device.
- a distal end of the injection device is protected by a device cap which engages in a coupling element of the injection device and is thus protected against unintentional loosening in the distal direction.
- the additional module can also engage in the coupling element and thereby secure the module against proximal movement.
- the additional module in turn, has its own coupling elements, which allow an adapted device cap to be attached to the additional module when the additional module is installed.
- WO 2018/036938 A1 shows an additional module which engages with a pretensioned pin in a recess in the housing of an autoinjector and thereby secures the additional module against axial displacement. This engagement is released by turning a knob or lever which protrudes over a proximal end face of the additional module and is guided by two fingers of the user, whereupon the additional module can be removed again.
- the autoinjector comprises a release button which is completely surrounded or covered by the attached additional module, so that in this case it can at best be operated indirectly or indirectly by a user.
- WO 2003/011373 A1 describes a modular injection device with a reusable dosing and actuation module comprising a counting and display device and with a disposable reservoir module comprising a mechanism holder and a carpule holder.
- a locking engagement by a locking element on a locking ring of the dosing and actuation module in a groove of the mechanism holder is released by pressing an unlocking button on the locking ring and against a return spring in the radial direction.
- An unlocking lock allows the Locking engagement only at the end of the dispensing movement, when a proximal actuating element is moved maximally in the distal direction.
- the actuating element To fully insert the reservoir module and to lock it, the actuating element must be pressed against a spring axially supported on the housing of the dosing and actuating module and the unlocking button must be pressed at the same time.
- a medicament in this context includes any flowable medical formulation which is suitable for controlled administration by means of a cannula or hollow needle, for example a liquid, a solution, a gel or a fine suspension containing one or more medicinal active ingredients .
- a medicament can be a single agent composition or a premixed or co-formulated multiple agent composition from a single container.
- the term includes in particular drugs such as peptides (e.g. insulins, drugs containing insulin, GLP-1-containing and derived or analogous preparations), proteins and hormones, biologically obtained or active substances, substances based on hormones or genes, nutritional formulations, enzymes and other substances both in solid (suspended) or liquid form.
- drugs such as peptides (e.g. insulins, drugs containing insulin, GLP-1-containing and derived or analogous preparations), proteins and hormones, biologically obtained or active substances, substances based on hormones or genes, nutritional formulations, enzymes and other substances both in solid (suspended) or liquid form.
- This object is achieved by an injection system with the features of the independent claim.
- Preferred embodiments of the invention are the subject of the dependent claims.

- the release movement of the release element comprises a movement exclusively in a plane perpendicular to the longitudinal axis of the injection device or a linear movement in a direction at least approximately perpendicular to the longitudinal axis.
- the release movement is preferably a pure rotary movement around the longitudinal axis or a pure linear movement in a direction mainly perpendicular to the longitudinal axis, i.e.
- the release movement includes in particular no screwing movement in the longitudinal direction and no tilting of a lever about an axis different from the longitudinal axis.
- the release movement is the only action to be performed by the user, in particular no unlocking of the additional module or no specific state of the injection device is required. Because the release movement of the release element is at least approximately perpendicular to the activation direction of the dispensing button, the risk of confusing the two movements is minimized compared to an injection system in which both a dispensing button and a release element are pushed or pushed in the same direction.
- the injection device itself does not have the ability to communicate with another device, but can certainly be adapted to interact with the additional module, for example through suitable openings in the device housing or through movable actuators such as magnets or sliding contacts, the positions of which are clearly recognized by the sensor of the additional module can be.
- the injection device is preferably a disposable injection device without the possibility of the container being replaced by a user, or else a reusable injection device.
- the injection device is further preferably an injection device with variable dose setting, comprising a dose setting button arranged at the proximal end for setting a dose to be dispensed by means of a turning and / or screwing movement.
- the dose setting button can also preferably be grasped and operated directly by the user when the additional module is attached, and is therefore not surrounded or otherwise covered by the additional module.
- the injection device can also be provided for a single delivery of a fixed dose. The injection device is operated manually either by transferring a dispensing force of the user to the dispensing button, or it comprises a pretensioned spring which is released for automatic dispensing by pressing the dispensing button.
- the additional module is generally sleeve-shaped and has a rigid receiving area with an opening adapted to the cross-section of the injection device for receiving the injection device, so that the injection device cannot be removed from the receiving area or even fall transversely to the longitudinal axis when it is attached. Without impairing the mutual alignment of the additional module and injection device, the receiving area can have a side opening or a transparent window through which a label on the device housing is visible.
- An axial extension of the additional module is chosen so that a dose display window of the injection device for displaying a set dose is not covered by the attached additional module and the dose display remains directly visible to the user.
- the sensor unit is not designed to read a displayed dose, but is based on an optical, mechanical or electrical, including magnetic or inductive, detection of processes or states in the injection device.
- the sensor unit preferably comprises at least one single or multi-axis acceleration sensor, a single or multi-axis gyroscope sensor, an inertia sensor, a piezo-based structure-borne sound microphone, or a comparable sensor for detecting movements of the injection device.
- These movements include both movements of the Injection device in the room, which are carried out by a user, as well as movements of the injection device which are caused by a mechanism in the injection device, for example oscillations, vibrations or sound waves from a pouring click.
- a boundary surface of the receiving area rests as closely as possible on a support surface of the injection device.
- the release movement is a linear movement which is carried out by the user by pressing or pushing the release element.
- this linear movement requires the additional module to be aligned with the user, which is a noticeable difference to a rotationally symmetrical pour-out button and makes confusion even more difficult for the user.
- the release element is provided in the distal half of the additional module, preferably at the distal end of the additional module.
- the release element is as far away from the pouring button as possible, which makes confusion even more difficult.
- the release element is part of a handle for one-handed gripping and guiding of the additional module and the injection device used.
- the handle surrounds the receiving area and extends in the direction of the longitudinal axis to at least half a hand's width of a user or at least 3 cm.
- the surface of the release element protrudes at the transition to the surface of the module housing no more than 2 mm, preferably no more than 1 mm over the latter, or is lowered no more than 2 mm, preferably no more than 1 mm compared to the latter.
- the surface of the release element thus forms an at least approximately seamless and stepless continuation of the surface of a module housing of the additional module immediately surrounding the fastening element.
- a handle or operating surface of the fastening element does not need to be completely even or flat, it can also include an edge at the transition to a side surface of the module housing, but explicitly excludes levers or knobs protruding from the module housing as fastening elements.
- the handle is arranged or configured in such a way that when a user grips the handle in a first or injection handle position with a first hand, it encompasses and touches both parts of the module housing and the surface of the release element. In this grip position, all relevant manipulations can be carried out with the injection system, for example placing it on the injection site, Pierce and pour out by touching the pour out button with the thumb of the first hand.
- the receiving area for receiving the injection device is designed by pushing the injection device in the distal direction or by pushing the additional module onto the injection device in the proximal direction.
- the injection device comprises a distally directed stop or stop surface for limiting the movement of the additional module on the injection device in the proximal direction. This stop surface is preferably formed at the transition between a distal carpule holder and a proximal device housing of the injection device.
- a dose selection button, and optionally also a dose display, at the proximal end of the injection device is not touched or encompassed by the additional module, so that the receiving area does not have to be matched to the dimensions of the dose selection button and this can therefore have a greater extent perpendicular to the longitudinal axis than that Housing of the injection device.
- the injection device comprises a proximally directed holding surface which is formed on an indentation or embossment of the injection device and deviates radially or perpendicularly to the longitudinal axis from the surface of the device housing.
- a holding element of the holding mechanism of the additional module engages behind the holding surface in the attached state and forms a form fit with the holding surface so that the additional module is held or secured against a separating movement in the distal direction and can transfer forces of the user in the distal direction to the injection device.
- the holding surface is part of an indentation, for example a groove or recess, or part of an indentation, for example a flange or a rib, in the surface of the device housing of the injection device.
- the embossing is preferably not part of a dose display window of the injection device for displaying a set dose, so that the dose display window is not covered by the additional module and the dose display remains directly visible to the user.
- the additional module is locked on the injection device and can be a There is no frictional connection with the surface of the injection device or even plastic deformation of the surface of the injection device caused by claws on the additional module.
- the injection device comprises a distal carpule holder for receiving a container and a proximal device housing for receiving a dispensing mechanism, the carpule holder being reversibly detachable or, after the container has been initially picked up, permanently non-detachably connected to the device housing.
- the holding surfaces are formed by embossings and / or embossings on the carpule holder, so only the carpule holder, but not the device housing with the dispensing mechanism, has to be exchanged or adapted for changed holding surfaces.
- embossments on the carpule holder are preferably formed as bulges on a flange or flange section, which protrude over an adjacent surface of the device housing, the flange also forming the stop surface at the same time.
- the holding surfaces on the injection device are preferably formed by embossings or impressions which are different from knobs on the injection device for fixing a device cap.
- the embossments are axially positioned so that the same device cap can be attached with or without an additional module; the knobs for fixing the device cap are not used by the holding mechanism.
- the fastening element snaps or engages in a stable fastening position at the end of the fastening movement.
- the fastening element can thus be released again at the end of the fastening movement without making the separating movement of the injection device and the additional module impossible, or so that other grip positions can be selected for the separating movement.
- the fastening element has two end positions, the fastening position of the fastening element differs visually clearly from the holding position, which results in an initial and permanent holding state feedback for the user.
- the fastening element is biased into a holding position by a spring mechanism and must be actively held in the fastening position by the user at least at the beginning of the separating movement.
- the fastening element executes a holding or locking movement directed against the movement of the jaw, in which the holding element of the holding mechanism moves into engagement with the holding surface and the additional module is locked with the injection device.
- the holding element is formed in one piece with the eyelet element or at least in one piece Direction of holding / releasing movement rigidly coupled.
- the release element is moved from a release to a holding position by a deflecting mechanism or by unlocking a drive element indirectly via the axial insertion movement of the injection device; no further locking element has to be actuated by the user.
- the release element thus serves as an operating and locking device at the same time.
- the holding mechanism comprises a control element which, when the injection device is inserted, is moved under tension of a control spring and thereby unlocks the release element for the holding movement from a release position into a holding position.
- the holding or locking movement is preferably carried out automatically, for example by an unlocked drive element such as a return spring, which means that a clearly audible locking click can be reproducibly generated as an additional holding status feedback to the user.
- the or a first injection device has openings or impressions which differ significantly from a surface of the injection device surrounding them.
- the additional module has grooves corresponding to the embossments in a boundary surface of the receiving area for axial guidance of the embossments or the injection device when inserting into the additional module, and / or holding elements corresponding to the embossments for engaging the embossments.
- a further or a second injection device differs from the said injection device only in the form or embossing and in a medical indication.
- Differences in the shapes or impressions result, for example, from the number, arrangement and / or shape of discrete shapes or indentations, differences in the medical indication are based on the active ingredient, formulation, shelf life, use, therapy and / or patient, as well as the corresponding information on the label. Individualized features or impressions can prevent the additional module from being intentionally or unintentionally placed on the additional injection device, which is identical except for the differences mentioned.
- the additional module has a charging socket for connecting a charging cable for charging an electrical energy store of the additional module.
- the charging socket is arranged in such a way that it is made inaccessible by the injection device used, in particular the charging socket opens into the receiving area and is thus directly covered by the injection device.

- the control spring 25 is a non-planar spring ring or a spring clip with an opening for the injection device, which is supported in each case at two locations on the module housing or on the control element which are opposite with respect to the longitudinal axis.
- the release button 21 again comprises two lateral parallel arms 21d with recesses 21e, in which locking cams 24a of the control element engage in the release position, and with holding elements which, in the holding state, engage behind the features of the injection device (not shown).
- the return spring 23 is a compression-loaded helical spring.
- FIG. 18 above shows a device cap detector with a tilting element 27 which tilts around a pivot point 27a as soon as the device cap is placed on or removed from the cartridge holder of the injection device used in the additional module in the proximal direction (from the left in FIG. 18).
- a first or distal leg 27b of the tilting element is held in an approximately axial alignment by the return spring 23 and is pressed upwards from this position by a proximal edge of the device cap (in the direction of the arrow).

- the release button 21 is released for radial movement perpendicular to the longitudinal axis (upwards in FIG. 18), as described, and the corresponding movement or end position of the lever 21h is recognized by the switching element 28b.
- the presence of the injection device is therefore only detected here at the very end of the insertion movement, and not already after a partial insertion.
- the injection device detector can be provided as an alternative or in addition to the device cap detector.
- the switching elements 28a, 28b preferably comprise electronic microswitches, sliding contacts, or optical detectors; they are arranged on a printed circuit board that is fixedly mounted in the module housing.
- FIG. 19 shows five different versions of the features 11c on the flange of the carpule holder, based on the version according to FIG. 4 in the middle (far left).
- the five versions differ in particular with regard to the number of forms, their arrangement or distribution over the circumference of the carpule holder, and their shape in the sectional plane shown perpendicular to the longitudinal axis.
- the shape includes both a width or extension in the circumferential direction, a height or extension in the radial direction, as well as a contour of the individual features, and in particular deviations from a perfectly radial or circular contour section.
- FIG. 19 shows, in a cross-section perpendicular to the longitudinal axis, three different versions of impressions lld on the carpule holder 11, together with the release element 21 of a suitable additional module.
- the release element 21 forms an opening for the injection device and functions with a return spring (not shown) analogously to the embodiment from FIG. 12.
- the release element has a section opposite the push button with inwardly directed embossments as holding elements for engaging in the embossments in the carpule holder.
- An additional module which corresponds to one of the last four versions in FIG. 19 above or is adapted to such cannot be placed on an injection device with one of the other versions.
- an injection device with the first version can be inserted into an additional module for the second version.
- one-to-one assignments of injection devices to additional modules can be generated. Individualized features or impressions can prevent an additional module from being placed on the wrong injection device intentionally or, if, for example, several injection devices are in use in the vicinity of a patient.
- a wrong injection device in the present context is a Injection device, which is identical except for the mentioned differences in the characteristics or impressions but is intended for a different medical indication.
- Differences in the medical indication include different active ingredients, formulations, shelf lives, therapies and / or patients, as well as the corresponding information on the label.
- the features can also be arranged on the housing of the autoinjector or at another point of the carpule holder, with at least the axial arrangement, in particular of those features that are not gripped from behind by a holding element of the release element, can be arbitrary for purely axial insertion movements.
- the attachment of an unsuitable additional module can already be prevented, depending on the axial arrangement of the embossings or, in the case of embossings, the movement of the holding elements at the attempted transition to the holding state.
- the additional module has a charging socket for a charging plug 31 of the charging cable, for example a USB-C port, which is only accessible from the receiving area 20a or can be contacted by a user with a standard charging cable.
- the charging socket is covered by an inserted injection device in the receiving area, thereby ensuring that a charging cable must be removed again before the additional module is put into operation or before the injection device is inserted.
- the charging plug 31 can be contacted in a straight line through the opposite window 20c in the module housing 20 and transversely through the receiving area 20a.
- the size of the window 20c is matched to the legible surface of a label on the injection device and thus offers sufficient space for manipulation of the charging cable, in particular to grip the charging plug 31 with two fingers.
- An alternative solution to prevent the charging plug from being plugged in when the injection device is inserted involves moving the charging socket at least partially behind a panel in the surface of the module housing when the injection device is pushed in, or a bistable cover, which is used to release the charging socket exclusively and only when the injection device is missing an axial access of the receiving area can be moved.
- the additional module 2 has touch sensors 20b. These serve to detect contact with the additional module and, in particular, gripping of the same. When put on, it becomes an imminent one Manipulation closed and, for example, a sensor status activated. For this purpose, every conceivable possibility of grasping the additional module should be able to be reliably detected, in addition to a grip with the whole hand in particular also a grip in the manner of tweezers with only two fingers on opposite sides of the additional module.
- the additional module therefore has sensor areas on both side surfaces, on the top surface, and on the end surfaces. Exemplary capacitive touch sensors are preferably stuck onto the module housing as a label or wrapped as a film with the material of the module housing in an injection molding process.
- the device cap detector from FIG. 18 above can also be used to detect an attached or removed device cap for an anticipatory change in the state of the additional module.
