[0001] Technical Field, Background Technology, and Invention Content

[0002] The present invention relates to a delivery device for intravitreal delivery of fluids, particularly fluids, according to the preamble of claim 1 or 2, which is preferably used in ophthalmology.

[0003] The present invention generally relates to the field of delivery devices for administering / delivering fluids, particularly drugs, to patients, i.e., humans or animals.

[0004] The delivery device according to the invention is preferably adapted for the (direct) delivery, particularly injection, of a drug into the eye of a human or animal, especially the vitreous body, anterior chamber, and / or posterior chamber. Therefore, the invention particularly relates to intravitreal injection delivery / delivery devices for ophthalmic purposes, particularly for fluids (especially drugs). However, the delivery device according to the invention can also be used for the delivery / injection of fluids (especially drugs) into other parts of the human or animal body.

[0005] WO 2014 / 005728 A1 relates to a small-volume syringe for ophthalmic injection, wherein the syringe is pre-loaded with a drug and includes a body, a stop, and a plunger. The plunger includes a plunger contact surface arranged to contact the stop such that the plunger can be used to push the stop toward an outlet, thereby delivering fluid contained within the syringe.

[0006] US 2006 / 0069350 A1 relates to a medical syringe pen having a syringe and a housing for receiving the syringe. The pen includes a drive mechanism and an actuation member for releasing the drive mechanism and the actuation device to deliver fluid from the syringe to the user.

[0007] US 2010 / 0231102 A1 relates to an intravitreal injection device, including an injection assembly adapted to receive a syringe. The injection assembly is adapted to automatically deliver the syringe to a patient's eye and then disperse fluid contained in the syringe into the eye.

[0008] The object of the present invention is to provide an improved—particularly purely mechanical—feeding / delivery device that is user-friendly and / or simple, intuitive and / or safe to use and / or minimizes or at least reduces the risks of misapplication, misuse, contamination, incorrect and / or inaccurate dosage and / or bubble delivery / feeding, and / or minimizes or at least reduces the requirements and / or complexity of the manufacturing process of the feeding device.

[0009] The above objective is achieved by the feeding device according to claim 1 or 2. Advantageous further improvements are the subject of the dependent claims.

[0010] The feeding / delivery device according to the invention, hereinafter referred to as a feeding device, is preferably adapted to (non-movably) hold a container for and / or containing fluids, particularly pharmaceuticals, in a cylindrical shape.

[0011] Preferably, the feeding device includes a container and / or a plunger / piston / stop that is movably arranged within the container, particularly by axial movement of the plunger / piston / stop (hereinafter referred to as the stop) toward the outlet of the container, such that the fluid contained in the container is dispersed.

[0012] In addition, the feeding device includes a frame / chassis, referred to below as a frame, preferably wherein the container is or can be particularly immobilized held by the frame and / or at least partially arranged within the frame.

[0013] The feeding device includes an actuation mechanism for actuating the feeding device and / or moving the stop within the container, particularly for so-called priming of the feeding device before fluid is fed and / or for dispersing fluid out of the container, as will be explained below.

[0014] The feeding device, particularly its actuation mechanism, comprises: a main unit acting directly and / or axially on a stop, a preloaded / compressed drive spring acting directly and / or axially on the main unit, a first actuation portion and a second actuation portion, wherein the first actuation portion and the second actuation portion are movably attached to a frame, and / or wherein the main unit is axially movable relative to the frame and / or arranged within the frame, and / or wherein, by actuating the first actuation portion and / or the second actuation portion, the main unit is axially movable relative to the frame, particularly for activating the feeding device and / or dispersing fluid from the container.

[0015] The actuation mechanism of the feeding device is preferably configured to move the main unit, the stop and / or the drive spring (axially) by moving the main unit, the stop and / or the drive spring during startup, before feeding, from the initial / unactuated position to the feeding / ready-to-use / start position and / or by actuating the first actuation part, and / or during feeding from the feeding / ready-to-use / start position to the final / actuated / end-of-use position after startup and / or by actuating the second actuation part.

[0016] According to one aspect of the invention, the feeding device, particularly the actuation mechanism, includes a lead screw, wherein a first actuating portion and a main unit (directly) interact movably with each other and / or (directly) are movably connected to each other by means of the lead screw, and / or wherein the first actuating portion is (manually) rotatable, particularly relative to the shelf and / or container, so as to axially move the main unit, particularly relative to the shelf and / or container, preferably such that the rotation of the first actuating portion axially drives the main unit and / or (compressed) drive spring toward a stop and / or away from the initial / unactuated position into a feeding / ready-to-use / start position.

[0017] Preferably, the first actuating portion forms the axial end and / or (rotatable) cap of the feeding device, which can be manually actuated, in particular rotated, to move the main unit axially.

[0018] By actuating, particularly rotating, the first actuating part, thereby moving the main unit, the stop and / or the drive spring, it is possible to – at least partially manually – activate the feeding device and / or eject the air / gas contained in the container and / or the needle attached thereto.

[0019] In this way, the feeding device can be started up in a simple, intuitive and user-friendly manner.

[0020] In the context of this invention, the term "prime" or "priming" preferably refers to the (necessary) preparation of the feeding device (immediately) before feeding the fluid contained in the feeding device, particularly its container.

[0021] Preferably, during startup, the main unit moves (axially) such that and / or until the main unit, in particular its plunger / connecting rod, abuts against the stop.

[0022] Most preferably, during startup, the main unit moves (axially) such that the main unit, in particular its plunger / connecting rod, moves / pushes the stop – particularly toward the outlet – and / or causes a (small) portion of the fluid to be dispersed and / or air (i.e. air bubbles contained in the fluid, container) and / or the needle attached thereto to be removed, in particular pushed out.

[0023] The feeding device is preferably held vertically during startup, in particular such that the outlet of the container and / or the needle attached thereto points upward and / or air can be at least partially expelled from the container.

[0024] Preferably, the volume contained in the container after activation corresponds to the expected / predetermined dose to be delivered to the patient / user.

[0025] Typically, the volume of fluid contained in the (pre-filled) container exceeds the volume of the dose to be delivered, such that air contained in the fluid, in the container, and / or needles attached thereto can be at least partially removed by activation without affecting the dose to be delivered.

[0026] However, the activation of the feeding device does not mean that the container is actually filled with fluid and / or that a portion of the fluid is dispersed. In particular, the actuation mechanism, preferably the first actuation part, can be actuated even if the container is empty and / or not moving and / or acting on the stop.

[0027] In other words, “prime” / “priming” specifically means that the main unit, stop and / or drive spring move from the initial / unactuated position to a defined position, hereinafter referred to as the feed / ready-to-use / priming position, especially before fluid feeding and / or by actuating the first actuation part.

[0028] Accordingly, all actions performed before the fluid is supplied and / or the second actuation part is aroused are considered to be the start-up and / or start-up process.

[0029] Initiation is preferably performed / completed solely by (full) actuation, particularly by rotating the first actuation part.

[0030] In the context of this invention, the term "administer" or "administration" preferably refers to the delivery / dispersion of fluid from a delivery device, preferably its container, and most preferably via an injection needle attached thereto (in practice).

[0031] Although preferably, the delivery device according to the invention is used to deliver fluid, particularly a drug, directly to the patient’s body, for example, by using an injection needle and / or by injecting the fluid directly into the patient’s eye, particularly the vitreous body, the term “administer” / “administration” also refers to the delivery / dispersion of fluid in the absence of a patient.

[0032] Preferably, “administer” / “administration” means and / or includes the movement of the main unit and / or the stop from the administer / ready-to-use / start position to the final / actuated / end-of-use position, especially after start-up and / or after (fully) actuating the first actuation section.

[0033] The initial / unactuated position, referred to below as the initial position, is preferably the (axial) position of the main unit, the stop and / or the drive spring relative to the frame and / or the container before the feeding device is activated and / or the first actuation part is actuated and / or in the initial state of the feeding device.

[0034] In the initial state of the feeding device and / or when the main unit, the stop and / or the drive spring are in the initial position, the first actuation part and the second actuation part are not actuated and / or the drive spring is (maximally) tensioned.

[0035] Preferably, in the initial state of the feeding device and / or when the main unit, the stop and / or the drive spring are in the initial position, it is not possible to (directly) actuate the second actuation part and / or (directly) feed fluid.

[0036] The main unit, stop, and / or drive spring can be moved out of the initial position and / or from the initial position to the feed / ready-to-use / start position, particularly by actuating the first actuation part only.

[0037] The feed / ready-to-use / start position, hereinafter referred to as the feed position, is preferably the (axial) position of the main unit, stop and / or drive spring relative to the frame and / or container in the following situations: (immediately) after start-up and / or (immediately) after (fully) actuation, especially rotation, after the first actuation portion and / or (immediately) before feed is achieved and / or in the feed / ready-to-use / start state of the feed device (hereinafter referred to as the feed state).

[0038] In the feeding state of the feeding device and / or when the main unit, the stop and / or the drive spring are in the feeding position, the first actuating part is (fully) actuated and the second actuating part is (stationary) not actuated.

[0039] In the feeding state / position, compared to the initial state / position, the main unit, stop, and / or drive spring are arranged closer to the outlet of the feeding device, particularly the container, and / or further away from the first actuation part. Specifically, compared to the initial state / position, the main unit and / or stop are further inserted into the container in the feeding state / position.

[0040] When the delivery device is in the delivery state and / or when the main unit, stop and / or drive spring are in the delivery position, the main unit, in particular its plunger / linkage, abutting the stop and / or delivery device is ready for use, the second actuation part can be actuated (directly) and / or fluid can be delivered to the patient without performing any further steps other than actuating the second actuation part.

[0041] Preferably, in the feeding state / position, it is impossible to (again) actuate and / or reverse the actuation of the first actuation portion.

[0042] The final / actuated / use end position, hereinafter referred to as the final position, is preferably the (axial) position of the main unit and / or stop relative to the frame and / or container in the following situations: (immediately) after feeding and / or after (fully) actuating the second actuation part and / or in the final / actuated / use end state of the feeding device (hereinafter referred to as the final state).

[0043] In the final state of the feeding device and / or when the main unit and / or the stop are in the final position, feeding has been achieved, the second actuating part is (fully) actuated and / or the driving spring / its spring force / energy is at least partially released / expanded.

[0044] In the final state / position, compared to the initial and / or feeding state / position, the main unit and / or the stop are arranged closer to the outlet of the feeding device and / or further away from the first actuation part.

[0045] Preferably, the main unit and / or stop are further inserted into the container in the final state / position compared to the initial and / or feeding state / position.

[0046] In particular, the drive spring is less tensioned in the final state / position than in the feed and / or initial state / position.

[0047] However, it is preferable that – for dosage accuracy – the drive spring remains taut, or in particular compressed, in the final state / position.

[0048] In particular, no additional fluid can be dispersed / delivered in the final state and / or after reaching the final position.

[0049] Preferably, it is impossible to actuate and / or reverse the actuation of the second actuation part in the final state and / or after reaching the final position.

[0050] As already mentioned, the first actuation part is preferably actuated by rotating the first actuation part (manually) relative to the shelf and / or container, most preferably about and / or at least substantially transverse / perpendicular to the main axis of the delivery device and / or the injection direction.

[0051] The second actuation part is preferably actuated by pressing the second actuator (manually) relative to the shelf and / or container, most preferably around and / or at least substantially transverse / perpendicular to the main axis of the feeding device and / or the injection direction.

[0052] In this way, the potential impact of the actuation of the first actuating portion and / or the second actuating portion on the injection side is minimized or at least reduced.

[0053] According to another aspect of the invention, which can also be implemented independently, the drive spring of the actuation mechanism / its spring force / energy is released / expanded by actuation, particularly rotation, of the first actuation portion and / or at least partially during startup, particularly at the end of startup and / or before delivery, and by actuation, particularly pressing, of the second actuation portion, and / or at least partially (further) released / expanded after startup and / or during delivery.

[0054] In other words, the first actuating part is configured to at least partially release, in particular expand, the driving spring / its spring force / energy in the first step, and the second actuating part is configured to at least partially (further) release, in particular expand, the driving spring / its spring force / energy in the second / subsequent step, preferably wherein the second actuating part can only be actuated after the first actuating part has been (fully) actuated and / or in the feeding state of the feeding device and / or in the feeding position of the main unit and / or the stop.

[0055] Preferably, the first actuation portion is configured to move the main unit, the stop, and / or the drive spring – particularly together and / or as a unit – from an initial position to a release / disengagement position, wherein the drive spring / its spring force / energy is at least partially released / expanded, such that further / subsequent movement of the main unit and / or the stop is supported and / or completed by means of the drive spring (particularly its spring force), and / or such that the main unit and / or the stop is further / subsequently moved from the release position to the feed position – particularly automatically and / or individually – by means of the drive spring, particularly its spring force.

[0056] In other words, the main unit, stop, and / or drive spring are first moved, manually and / or (only) by actuation, particularly by rotating the first actuation part, in a first step to move and / or from the initial position to the release / disengagement position, and then automatically and / or – particularly individually – by partially releasing the drive spring, i.e. by the spring force / energy of the drive spring, in a second step to move and / or from the release / disengagement position to the feed position.

[0057] In particular, the start-up and / or the end of the start-up process is preferably accomplished solely by the drive spring, i.e., its spring force.

[0058] The release / disengagement position, referred to below as the release position, is preferably the (axial) position of the main unit, stop and / or drive spring relative to the frame and / or container during startup and / or between the initial position and the feed position and / or (immediately) before reaching the feed position, the feed state and / or during startup.

[0059] During the release position and / or startup and / or (immediately) before reaching the feed position, the drive spring / its spring force / energy (automatically) at least partially releases / expands, in particular enabling the subsequent movement of the main unit and / or the stop toward the feed position and / or the transition of the feed device from the initial state to the feed state to be accomplished and / or supported by the drive spring.

[0060] Therefore, according to one aspect of the invention, the movement of the start-up and / or the main unit and / or the stop during start-up and / or from the initial position to the feed position is achieved in a semi-manual / semi-automatic manner and / or manually, i.e. by actuation, particularly by rotating the first actuation portion, and automatically, i.e. by at least partially extending / releasing the drive spring / its spring force.

[0061] Preferably, compared to the initial state and / or when the main unit, stop and / or drive spring are in the initial position, the drive spring / its spring force / energy is at least partially expanded / released and / or less tightly stretched in the feed state and / or when the main unit, stop and / or drive spring are in the feed position.

[0062] Compared to fully automatic start-up, the advantages of semi-manual / semi-automatic start-up are improved availability of the feeding device and better control of the start-up process.

[0063] The drive spring, especially its spring force, facilitates the transition of the feeding device from its initial state to the feeding state. Furthermore, during startup, the drive spring / its spring force / energy release / expansion clearly indicates to the user / operator that the manual portion of the startup process has been correctly completed.

[0064] Furthermore, critical components, namely those that mechanically interact with each other during delivery, are moved / pushed into place during startup by means of a drive spring, so that the impact caused by the expansion / release of the drive spring / its spring force / energy occurs first during the (less critical) startup period and before the (more critical) fluid delivery. In this way, the risk of incorrect and / or inaccurate dosing during delivery, as well as the effects of dimensional tolerances, are reduced.

[0065] According to another aspect of the invention, which can also be implemented independently, the first actuation portion can be actuated to move the main unit, the stop, and / or the drive spring—particularly together and / or as a unit—axially from an initial position to a release position. Preferably, the actuation mechanism includes a fastening element configured to prevent the extension / release of the drive spring / its spring force / energy during the movement of the main unit and / or the drive spring from the initial position to the release position, and particularly to automatically at least partially extend / release the drive spring / its spring force / energy at the release position and / or when the release position is reached, preferably such that the feed position is reached automatically and / or solely by means of the drive spring, i.e., its spring force, and / or without further actuation of the first actuation portion, as already explained.

[0066] In this way, the corresponding advantages can be achieved.

[0067] Preferably, the first actuating portion includes or forms a fastening element, wherein the fastening element is realized as an internal thread engaging the main unit, particularly its end, and / or wherein the fastening element can be disengaged by actuation, particularly rotation of the first actuating portion.

[0068] According to another aspect of the invention, which can also be implemented independently, the second actuation portion can be actuated, in particular pressed, to at least partially (further) extend / release the drive spring / its spring force / energy and / or move the main unit and / or the stop from the feed position to the final position, wherein the actuation mechanism, in particular the second actuation portion, includes a blocking element / segment configured to axially block the main unit, in particular the axial movement of the main unit, in the feed position, i.e. before the actuation of the second actuation portion, and also in the final position, i.e. after the actuation of the second actuation portion.

[0069] In other words, at the end of startup and further at the end of feeding, the blocking element / segment stops the axial movement of the main unit and / or the stop.

[0070] The blocking element / section is preferably configured to axially block the main unit in the following situations: (only) after the drive spring / its spring force / energy has been at least partially extended / released by means of the first actuating portion and / or when the feed position is reached, in the feed state of the feed device and / or after the start-up is completed and / or after the drive spring / its spring force / energy has been at least partially extended / released by means of the second actuating portion and / or when the final position is reached, in the final state of the feed device and / or after the feed is completed. However, in the initial state of the feed device and / or in the initial position of the main unit and / or the stop, the blocking element / section preferably does not axially block / engage the main unit.

[0071] Using the same blocking element to define the end of both initiation and delivery improves dosage accuracy and thus minimizes the requirements in the manufacturing process.

[0072] The main unit, particularly its plunger, preferably includes a first stop and a second stop, preferably wherein the first stop and the second stop are axially offset from each other, and / or wherein a blocking element is adapted to axially engage the first stop in the feed position / state and / or after the start-up process is completed, and / or wherein the (same) blocking element is adapted to axially engage the second stop in the final position / state and / or after the feed is completed.

[0073] According to another aspect of the invention, which can also be implemented independently, the feeding device includes an indicator portion indicating the state of the feeding device and / or the (axial) position of the main unit and / or the stop relative to the rack and / or the container, wherein the indicator portion is rotatable, particularly rotatably driven, (directly) by the (axial) movement of the main unit, preferably only after startup and / or while reaching the feeding position and / or only while the main unit is moving from the feeding position to the final position.

[0074] In this way, a simple and reliable (visual) indication of the status of the feeding device and / or the axial position of the main unit and / or the stop is provided, thereby reducing the risk of misuse of the feeding device due to possible misunderstanding of the status.

[0075] The indicator portion is preferably implemented as a hollow cylinder and / or sleeve, which is preferably rotatably arranged within the frame.

[0076] Preferably, the main unit extends axially through the indicator portion and / or the indicator portion (radially) surrounds / encloses the main unit, particularly its middle portion.

[0077] The indicator portion is preferably adapted to indicate the initial position, release position, feed position and / or final position of the main unit and / or stop, and / or the initial state, feed state and / or final state of the feed device, particularly by means of its rotational position relative to the main unit, container, stop and / or frame.

[0078] To rotate the indicator section, the main unit, particularly its intermediate portion, preferably includes at least one protrusion, such as a radially locating pin, preferably wherein the protrusion / pin protrudes into and / or engages a helical or inclined groove and / or surface of the indicator section, particularly causing axial movement of the main unit to rotate the indicator section. In this way, a simple mechanical coupling between the main unit and the indicator section is achieved.

[0079] Furthermore, the protrusion / pin and / or indicating device of the main unit can be seen from the outside of the feeding device, thereby indicating the status of the feeding device and / or the axial position of the main unit and / or the stop, especially the initial position, release position, feeding position and / or final position, preferably attached to the indicating part.

[0080] Most preferably, the protruding / pin and / or indicating device are adapted to indicate the status of the feeding device and / or the axial position of the main unit and / or the stop during startup, and the indicator portion is adapted to indicate the status of the feeding device and / or the axial position of the main unit and / or the stop during feeding.

[0081] In this way, availability is improved and / or the risk of misuse due to possible misunderstanding of the status of the feeding device is reduced.

[0082] Alternatively, at least during startup, the indicator portion is adapted to limit visibility into the feeding device and to focus the user's / practitioner's attention on the indicator portion and / or the pin.

[0083] Another aspect of the present invention relates to a method for operating a feeding device, wherein the method includes at least one of the following steps:

[0084] • (Manual) Rotate the first actuating part to move the main unit, stop, and / or drive spring axially relative to the frame and / or container, preferably together and / or as a unit, particularly by means of the lead screw of the actuating mechanism, and / or

[0085] • (Manual) actuation, particularly rotation, of the first actuating portion, thereby at least partially extending / releasing the drive spring / its spring force, particularly in the release position of the main unit and / or upon reaching the release position, and subsequently (manual) actuation, particularly pressing, of the second actuating portion, thereby at least partially (further) extending / releasing the drive spring / its spring force, particularly in the feed position of the main unit, and / or

[0086] • (Manual) actuation, particularly rotation, of the first actuating part, thereby (axially) moving the main unit, the stop, and / or the drive spring – particularly together and / or as a unit – from the initial position to the release position, wherein the drive spring / its spring force / energy, particularly in part, automatically extends / releases, and / or

[0087] • (Manual) actuation, particularly pressing, of the second actuating part, thereby at least partially extending / releasing the drive spring / its spring force / energy, which then moves, particularly pushing, the main unit and / or the stop from the feed position to the final position, wherein, in the feed position and / or before actuating the second actuating part and in the final position and / or after actuating the second actuating part, the main unit is axially blocked by means of the blocking element of the actuation mechanism, and / or

[0088] • The indicator part of the rotating feeding device is rotated by means of the (axial) movement of the main unit (especially its pin).

[0089] In this way, the corresponding advantages can be achieved.

[0167] The first moving part 70 preferably includes a handle / turntable 71, a collar 72 and / or a connector 73, preferably wherein the collar 72 (axially) is arranged between the handle / turntable 71 and the connector 73, and / or wherein the outer diameter of the collar 72 is larger than the outer diameter of the handle / turntable 71 and / or the connector 73.

[0168] The handle 71 preferably protrudes beyond the frame 20, particularly its axial opening 22B. The collar 72 preferably axially covers the frame 20 and / or the housing 30, particularly in the gap between the connector 73 and the frame 20 and / or in the gap between the frame 20 and the housing 30.

[0169] The first moving part 70 is preferably directly attached, in particular axially fixed, to the frame 20, especially the frame 22.

[0170] Preferably, the first actuating portion 70, particularly its connector 73, is axially attached, particularly pressed / clamped or clipped, to the frame 20, particularly the frame 22, and most preferably enters the axial opening 22B.

[0171] Preferably, the frame 20, particularly the frame 22, includes a plurality of retaining elements 22C that radially engage the first actuating portion 70, preferably a connector 73 and / or corresponding protrusions and / or recesses (not shown) formed therein, and most preferably such that the first actuating portion 70 is axially fixed to the frame 20, particularly the frame 22.

[0172] However, preferably, the first actuating part 70 is movable relative to the frame 20, particularly rotated, preferably in a predetermined rotational direction, such as... Figure 1 and Figure 2 As indicated by the arrow in the image.

[0173] Preferably, the actuation mechanism, particularly the first actuation part 70, can be actuated by manually rotating the first actuation part 70 relative to the frame 20.

[0180] Specifically, the reverse rotation stop 74 of the first actuation part 70 and the reverse rotation stop 22D of the shelf 20 engage with each other in a form-fitting manner in a direction opposite to the expected rotation direction and / or slide past each other in the expected rotation direction, for example by elastically / temporarily deforming / bending the reverse rotation stop 74 of the first actuation part 70 and / or the reverse rotation stop 22D of the shelf 20.

[0181] In this embodiment, the frame 20, particularly the frame 22, includes a counter-rotation stop 22D extending into the interior of the frame 20, particularly the receiver 22A, in the form of a flexible arm, and the first actuation portion 70 includes a plurality of counter-rotation stops 74 in the form of serrations. However, other construction solutions are also possible.

[0182] The reverse rotation lock reduces the risk of misuse of the feeder 100 via the first actuation part 70 and can provide tactile / auditory feedback during startup, thereby increasing the user-friendliness of the feeder 100.

[0183] Optionally, the shelf 20 and / or the first actuation portion 70 includes an actuation stop 22E to limit the actuation of the first actuation portion 70 relative to the shelf 20, particularly in the rotational direction, especially rotation.

[0185] The first actuating part 70 preferably includes a corresponding actuating stop (not shown), wherein, preferably, when the first actuating part 70 reaches a predetermined rotational position, particularly when it reaches a release position, the actuating stop of the first actuating part 70 abuts against the actuating stop 22E of the frame 20 in the circumferential direction.

[0186] As already mentioned, the feeding device 100—in addition to the first actuation part 70—also includes another second actuation part 80.

[0187] The second actuating part 80 is preferably attached radially / laterally to the frame 20, particularly the mounting part 21.

[0188] Most preferably, the second actuating part 80 and the container 10 are mounted to the shelf 20 from opposite sides, particularly the mounting member 21. In this way, the second actuating part 80 and the container 10 can be mounted to the shelf 20 independently of each other.

[0189] Preferably, the second actuating part 80 is preferably movably, in particular pivotally, attached to the frame 20, in particular the mounting part 21.

[0190] The second actuating part 80 preferably has a shell-like structure and / or covers the frame 20, particularly the mounting part 21, laterally, on one side, and / or partially.

[0191] Preferably, the second actuating part 80 is clipped into or clamped onto the frame 20, particularly onto the mounting member 21, and most preferably in a pivotable manner.

[0192] The feeding device 100, particularly the frame 20, most preferably the mounting member 21, and / or the second actuation portion 80 defines / limits the pivot P, preferably wherein the second actuation portion 80 is pivotable about the pivot P relative to the frame 20.

[0193] Best of all Figure 1 and Figure 2 As shown, the pivot axis P of the second actuation part 80 is preferably arranged transversely to, and in particular at least substantially perpendicular to, the main shaft A of the feeding device 100 and / or the rotation axis R of the first actuation part.

[0194] Preferably, the frame 20 includes or forms a pair of pivot pins 23, wherein the pivot pins 23 define a pivot P.

[0195] The pivot pin 23 is preferably implemented as a protrusion / pin extending laterally and / or radially from the frame 20.

[0196] The second actuation portion 80 preferably includes a pair of grooves 81, wherein each groove 81 is adapted to receive a corresponding pivot pin 23, and / or wherein each pivot pin 23 is (directly) clamped into a corresponding groove 81 of the second actuation portion 80.

[0197] However, other structural solutions are also possible, particularly in which the second actuation portion 80 includes or forms a pivot pin 23 and the frame 20 includes or forms a groove 81 for the pivot pin 23.

[0198] The second actuating portion 80 is preferably elongated and / or includes a first (axial) end 82 and a second (axial) end 83, preferably wherein the pivot axis P extends through the second actuating portion 80 at least substantially centrally and / or between the first end 82 and the second end 83.

[0199] Therefore, preferably, the second actuating portion 80 may be tilted relative to the frame 20 and / or the second actuating portion 80 may be implemented as an elbow.

[0200] Preferably, the second actuation portion 80, particularly the first end 82, includes or forms a preferably elliptical button 84, wherein the button 84 is configured to protrude radially and / or radially / laterally out of the feeding device 100, particularly through a radial opening 35 in the housing 30, particularly the second housing portion 32.

[0201] Preferably, the second actuation part 80 is actuated by pressing button 84, particularly toward the shelf 20 and / or the main axis A.

[0202] By actuating the second actuation portion 80, particularly by pressing the button 84, the second end 83 of the second actuation portion 80 is preferably raised and / or moved out of and / or toward the housing 30 from the shelf 20.

[0203] The second end 83 of the second actuating portion 80 is preferably realized as a radial, particularly plate-shaped protrusion and / or radially protruding into the frame 20, particularly the frame 22 of the frame 20, and / or toward the main shaft A.

[0204] Preferably, the second actuation portion 80, particularly its second end 83, includes or forms at least one actuation spring 83A, most preferably in the form of a flexible protrusion / arm.

[0205] The frame 20, preferably the frame 22, particularly the receiver 22A, preferably includes a bottom 22F, wherein the second end 83 of the second actuating portion 80, particularly the actuating spring 83A, is axially seated against the bottom 22F. In other words, the bottom 22F preferably serves as a support for the actuating spring 83A and / or forms a supporting surface.

[0206] In the initial state of the feeding device 100, the actuation spring 83A is preferably pre-tensioned, particularly against the bottom 22F, and most preferably such that the second actuation part 80 is actuated against the spring force / energy of the actuation spring 83A. In this way, the risk of accidental actuation of the second actuation part 80 is reduced.

[0207] The second actuating portion 80, particularly its second end 83, preferably includes or forms a frame 83B and / or a hole 83C, preferably wherein the main unit 50 extends through the frame 83B and / or the hole 83C.

[0208] By actuating the second actuation part 80, in particular the button 84, the (radial) position of the frame 83B and / or the hole 83C relative to the main unit 50 is changed, thereby axially blocking or releasing the main unit 50, as will be explained in more detail later.

[0209] Medical devices, such as delivery devices 100, are frequently sterilized, particularly by means of and / or exposure to sterilizing agents, especially sterilizing gases such as ethylene oxide. During such sterilization processes, it is especially important to expose all surfaces of the medical device that the user / practitioner may come into contact with to the sterilizing agent.

[0210] For this purpose, the housing 30 and / or the second actuation portion 80 preferably include at least one spacer 85, wherein the spacer 85 is adapted to maintain a gap between the housing 30 and the second actuation portion 80, particularly near the proximity button 84 and / or even in the initial / unactuated state of the feeding device 100.

[0211] In this way, the contact surface is maximized during sterilization of the delivery device 100. Specifically, a sterilizing agent, such as ethylene oxide, may flow into the gap between the housing 30 and the second actuation portion 80 during the sterilization process, so that the entire button 84 is exposed to the sterilizing agent during sterilization.

[0212] As already mentioned, the feeding device 100, and in particular its actuation mechanism, includes a main unit 50, preferably wherein the main unit 50 is movably arranged within and / or movable relative to the frame 20.

[0214] However, it is preferable that the stop 18 is not rigidly attached to the main unit 50, particularly its tip. Preferably, the stop 18 is only abutted against and / or loosely connected to the main unit 50, particularly its tip. In other words, the main unit 50 and the stop 18 are configured to engage only during compression and / or when the main unit 50 is pushed against the stop 18. The main unit 50 and the stop 18 are preferably configured to decouple under tension and / or when the main unit 50 is moved / pulled out of the container 10. This prevents the container 10 from drawing in air, for example, during the sterilization process.

[0215] In the initial state of the feeding device 100, the stop member 18 can also be axially spaced from the main unit 50, so that the main unit 50 only axially abuts the stop member 18 when the first actuation part 70 is actuated.

[0216] The main unit 50 is preferably elongated and / or rod-shaped.

[0217] Most preferably, the main unit 50 extends axially through the feeding device 100, preferably the frame 20, particularly from the first actuation part 70 through the frame 20 into the container 10.

[0218] Specifically, the main unit 50 extends out of the housing 30, particularly the second axial opening 34.

[0219] The main unit 50 preferably includes a plunger / connecting rod 51, an intermediate portion 52 and / or an end portion 53, wherein the intermediate portion 52 (axially) is arranged between the plunger / connecting rod 51 and the end portion 53.

[0221] The end portion 53 of the main unit 50 preferably includes or forms the (second) axial end of the main unit 50. Preferably, the end portion 53 is opposite to the stop 18 and / or mechanically interacts with and / or at least partially extends into the first actuation portion 70, as will be explained in more detail later.

[0222] The plunger rod 51 is preferably elongated and / or rod-shaped.

[0223] In this embodiment, the plunger rod 51 preferably comprises at least a generally rectangular cross-section. However, other structural solutions are also possible, particularly in which the plunger rod 51 comprises a circular cross-section.

[0224] The outer dimensions of the plunger rod 51 are preferably smaller than the inner diameter of the container 10, particularly its body 12, so that the plunger rod 51 can move freely and / or without friction within the container 10.

[0225] The plunger rod 51 preferably includes a front section 51A and a rear section 51B.

[0226] The front section 51A is preferably the section of the plunger rod 51 that extends at least partially into the container 10 and / or (directly) faces / bears the stop 18.

[0227] The rear section 51B of the plunger rod 51 is preferably the protruding container 10 of the plunger rod 51 and / or includes or forms a transition section between the front section 51A and the intermediate portion 52 of the main unit 50.

[0250] The frame 20 preferably includes, in particular, longitudinal and / or axial recesses 22H / 22J, wherein pins 52A / 52B are guided within the recesses 22H / 22J, particularly in the circumferential direction and / or to prevent or at least limit rotation of the main unit 50 relative to the frame 20.

[0251] Preferably, the indicating device, particularly pins 52A / 52B, is visible from the outside of the feeding device 100 and / or through the housing window 36, as shown. Figure 1 As shown. In this way, the axial position of the main unit 50 relative to the frame 20 is indicated and / or visible to the user / operator of the feeding device 100. Therefore, indicating devices, particularly pins 52A / 52B, are preferably used for both the guide 50 of the main unit and the indication of the axial position of the main unit 50.

[0252] The shelf 20 is preferably made at least partially of a transparent material. Most preferably, at least the section of the shelf 20 covering the indicator, particularly pins 52A / 52B, is at least partially transparent, such that the indicator, particularly pins 52A / 52B, is visible from the outside and / or through the housing window 36.

In this way, the risk of the main unit 50 being guided and jammed on both sides is reduced.

[0254] As already mentioned, the feeding device 100 preferably includes an indicator portion 40 to indicate the status of the feeding device 100 and / or the axial position of the main unit 50 relative to the frame 20.

[0255] The indicator portion 40 is preferably implemented as a hollow cylinder and / or sleeve.

[0256] The indicator portion 40 is preferably arranged within the shelf 20, particularly within the receiver 22A.

[0257] The main unit 50, particularly the middle part 52, is preferably arranged within the indicator part 40.

[0260] The indicator portion 40 is preferably rotatable relative to and / or within the frame 20, particularly the receiver 22A, and / or relative to and / or surrounding the main unit 50, particularly the intermediate portion 52. However, preferably, the indicator portion 40 is axially fastened within and / or secured by means of the frame 20.

[0261] According to one aspect of the invention, the indicator portion 40 is preferably (directly) rotatable by means of the main unit 50, particularly the axial movement of its pins 52A / 52B. Preferably, the indicator portion 40 is rotatably (directly) driven by the (axial) movement of the main unit 50, particularly its pins 52A / 52B.

[0262] In other words, actuation, particularly rotation of the first actuation portion 70, preferably causes axial movement of the main unit 50, which in turn causes rotation of the indicator portion 40.

[0263] According to a preferred embodiment (not shown), the indicator portion 40 is rotatably (directly) driven by the (axial) movement of the main unit 50 only after reaching the feed position / state and / or during the movement from the feed position / state to the final position / state, specifically to indicate when the final position / state has been reached.

[0266] Pins 52A / 52B preferably protrude radially into grooves / surfaces 42A / 42B, causing axial movement of the main unit 50, particularly pins 52A / 52B, to rotate the indicator portion 40 relative to the frame 20 and / or the main unit.

[0267] In this embodiment, the indicator portion 40 includes a first axial opening 41A and / or a first spiral groove / surface 42A for the first pin 52A and a second axial opening 41B and / or a second spiral groove / surface 52B for the second pin 52B. In this way, the indicator portion 40 can be prevented from getting stuck.

[0268] According to a preferred embodiment (not shown), the main unit 50 axially engages / abuts the spiral groove / surface 42A / 42B only after reaching the feed position / state and / or during the movement from the feed position / state to the final position / state, in particular such that the indicator portion 40 is rotatably driven by the (axial) movement of the main unit 50 only after reaching the feed position / state and / or during the movement from the feed position / state to the final position / state.

[0271] As already mentioned, the feeding device 100 can be activated, particularly by actuating, most preferably, rotating the first actuating part 70.

[0272] By actuating, particularly rotating the first actuating part 70, the main unit 50 moves (axially), in particular causing the plunger rod 51 to move / push the stop 18 further into the container 10 and / or toward its outlet.

[0273] The feeding device 100, particularly the actuation mechanism, preferably includes an actuator 90 that mechanically connects and / or interacts with the main unit 50 to the first actuation part 70, particularly causing the actuation of the first actuation part 70, especially its rotation, to cause axial movement of the main unit 50, particularly for starting the feeding device 100.

[0286] Preferably, the drive spring 60 is tensioned in the initial state of the feeding device 100, and most preferably compressed, in particular so that the first starter portion 91 and the second starter portion 92 are pushed away from each other by means of the drive spring 60.

[0287] Preferably, the drive spring 60 is implemented as a helical / coil spring and / or made of metal, particularly stainless steel.

[0288] The first starter portion 91 and the second starter portion 92 preferably each include a bottom 91A / 92A and / or preferably cylindrical walls 91B / 92B, in particular, wherein the bottom 91A of the first starter portion 91 and the bottom 92A of the second starter portion 92 axially define the spring chamber 93, and / or the wall 91B of the first starter portion 91 and / or the wall 92B of the second starter portion 92 radially define the spring chamber 93.

[0296] Therefore, the lead screw is adapted to convert the (manual) rotation of the first actuation part 70 into linear motion, particularly axial motion, of the main unit 50, drive spring 60, and / or starter 90.

[0297] The first actuating portion 70 preferably includes a thread 76, and / or the starter 90 preferably includes a thread 94, wherein the thread 76 of the first actuating portion 70 and the thread 94 of the starter 90 interact with each other (mechanically).

[0322] Preferably, the fastening element 77 includes or forms the thread 76 of the first actuating portion 70, and vice versa. However, other structural solutions are also possible, particularly in which the fastening element 77 and the thread 76 are implemented as separate parts / elements.

[0323] The fastening element 77 / thread 76 is preferably adapted to axially hold the first actuator portion 91 and the second actuator portion 92 / main unit 50 together, at least in the initial position / state, until the release position is reached and / or during the actuation of the first actuation portion 70 and / or during the movement of the stop 18, main unit 50, drive spring 60 and / or actuator 90 from the initial position to the release position.

[0324] Specifically, the fastening element 77 / thread 76 (axially) engages the threaded portion 92E of the second actuator portion 92, such that the second actuator portion 92, in particular the threaded portion 92E of the second actuator portion 92, cannot be pushed out of the first actuator portion 91, in particular its groove 91F, by means of the drive spring 60, at least in the initial position / state and / or until reaching the release position and / or during the actuation of the first actuation portion 70 and / or during the movement of the stop 18, the main unit 50, the drive spring 60 and / or the actuator 90 from the initial position to the release position.

[0325] As already mentioned, it is preferably impossible to actuate the second actuation part 80 during the initial state / position, during the actuation of the first actuation part 70, and / or during the movement of the stop 18, main unit 50, drive spring 60, and / or starter 90 from the initial position to the feed position.

[0326] Preferably, in the initial state / position, during the actuation of the first actuation portion 70 and / or during the movement of the stop 18, main unit 50, drive spring 60 and / or starter 90 from the initial position to the feed position, the main unit 50, in particular the plunger rod 51 (radially), blocks and / or restricts the movement of the second actuation portion 80.

[0327] The second actuating portion 80, particularly its second end 83, preferably framed by a frame 83B, preferably includes or forms a locking element 83E, wherein the locking element 83E preferably prevents the second actuating portion 80 from actuating in the initial state / position and / or before reaching the feed position / state, preferably as follows: Figure 6 As shown.

[0328] The locking element 83E preferably engages / abuts the main unit 50 radially, particularly the plunger rod 51, and most preferably prevents the second actuation portion 80, particularly its button 84, from being actuated, or in particular, from being pressed.

[0329] Therefore, it is preferable that the position and / or rotation angle of the second actuating portion 80, particularly relative to the pivot axis P, is at least substantially fixed and / or restricted during the movement of the stop 18, main unit 50, drive spring 60, and / or actuator 90 from the initial position to the feed position. This is achieved by means of the frame 83B that engages / abuts the main unit 50, particularly the plunger rod 51, from both sides. Figure 6 From below and above.

[0330] Specifically, the position and / or rotation angle of the second actuating part 80 are at least substantially fixed and / or restricted in the initial state / position and / or during the movement of the stop 18, main unit 50, drive spring 60, and / or actuator 90 from the initial position to the feed position, by means of a locking element 83E that engages / abuts the main unit 50, particularly the rod plunger 51, from one side. Figure 6 From below, and by means of a blocking element 83D that engages / abuts the main unit 50, particularly the plunger rod 51, from the other side, in Figure 6 From above.

[0331] Best of all Figure 5 As shown, the return locks, particularly the return stop 51E of the main unit 50 and the return stop 24 of the frame 20, are preferably not yet engaged and / or latched into the initial state / position.

[0332] By actuation, particularly rotation, the first actuation part 70, the stop 18, the main unit 50, the drive spring 60 and / or the starter 90 can be moved, particularly pushed out of the initial position, particularly from the initial position to the release position and / or from the release position to the feed position.

[0333] Preferably, due to the lead screw, the starter 90, particularly the first starter portion 91 and / or the second starter portion 92, and / or the main unit 50 can be unscrewed from the first actuation portion 70 by actuation, particularly by rotating the first actuation portion 70.

[0334] Until the release position is reached, the first starter section 91 and the second starter section 92 / main unit 50 preferably move together and / or move as a unit and / or do not move relative to each other.

[0335] In other words, the length of the drive spring 60 and / or the spring chamber 94 preferably remains the same and / or preferably does not change until the release position is reached and / or as long as the fastening element 77 / thread 76 of the first actuation portion 70 engages the starter 90, especially the first starter portion 91, most preferably its threaded portion 91E.

[0336] Figure 7 and Figure 8 The feeding device 100 is shown in the released position, i.e., after the actuation of the first actuation member 70.

[0337] The preferred release position is between the initial position and the feed position of the main unit 50, the stop 18, the drive spring 60 and / or the starter 90 relative to the frame 20 and / or the container 10 and / or after the first actuation part 70 is fully actuated and / or before (immediately) reaching the feed position / state and / or before (immediately) completing the start-up (axial) position.

[0338] By actuation, particularly rotation, the first actuation part 70, the stop 18, the main unit 50, the drive spring 60 and / or the starter 90 are axially moved, particularly towards the outlet and / or container 10 of the feeding device 100 and / or away from the first actuation part 70, preferably at least 5 mm or 8 mm and / or at most 30 mm or 20 mm, particularly at least substantially 10 mm.

[0339] In particular, on the one hand, the distance D between the bottom 91A of the main unit 50 and / or starter 90, especially the first starter portion 91, and on the other hand, the distance between the first actuation portion 70, especially its bottom, is increased.

[0340] In and / or upon reaching the release position, the drive spring 60 / its spring force / energy preferably (automatically) at least partially extends / releases, such that by means of the drive spring 60, subsequent movement of the main unit 50, the second starter portion 92, and / or the stop member 18 toward the feed position and / or toward the outlet of the feed device 100 is completed and / or supported, and / or such transition of the feed device 100 from the initial state to the feed state is completed and / or supported by means of the drive spring 60.

[0341] In and / or upon reaching the release position, the thread 76 / fastening element 77 and the second actuator portion 92, particularly its threaded portion 92E, separate (axially), preferably such that the drive spring 60 is partially released and / or partially extended, and / or such that, by means of the drive spring 60, the second actuator portion 92, particularly its threaded portion 92E, can be at least partially pushed out of the first actuator portion 91, particularly the groove 91F. In this way, the starting and / or reaching the feed position is accomplished.

[0342] Therefore, according to one aspect of the invention, the activation and / or movement of the main unit 50, the second actuator portion 92, and / or the stop member 18 during activation and / or from the initial position to the feed position is accomplished in a semi-manual / semi-automatic manner and / or both by manually, i.e. by actuating, particularly by rotating the first actuation portion 70, and automatically, i.e. by at least partially extending / releasing the drive spring 60 / its spring force / energy (when reaching the release position and / or from the release position to the feed position).

[0343] As already mentioned, the first starter portion 91 and the second starter portion 92 engage with each other and / or the second starter portion 92 is preferably configured to constrain the first starter portion 92 radially / rotatably and / or circumferentially, preferably such that the first starter portion 91 and the second starter portion 92 cannot rotate relative to each other, particularly at least during start-up and / or until the delivery position is reached.

[0344] According to a preferred embodiment (not shown), the first starter portion 91 and the second starter portion 92 are disengaged from each other and / or the second starter portion 92 is preferably configured to release the first starter portion 91 radially / rotatably and / or circumferentially, preferably such that the first starter portion 91 and the second starter portion 92 are rotatable relative to each other after starting and / or at least temporarily and / or when the delivery position is reached.

[0345] Preferably, after activation and / or when the delivery position is reached, the drive spring 60 / its spring force / energy is at least partially (further) extended / released, and / or by means of the drive spring 60, the first actuator portion 91 is moved, in particular rotated back into and / or toward the first actuation portion 70, most preferably until the first actuator portion 91 and the second actuator portion 92 engage with each other again and / or until the first actuator portion 91 strikes the corresponding stop of the second actuator portion 92.

[0346] In this way, clear audible / tactile feedback is provided to indicate the end of the start and / or when the delivery position is reached, especially the audible / tactile feedback attached to the return lock and / or different from it, preferably enabling the user / operator to clearly distinguish the start and / or when the delivery position / status is reached.

[0347] By actuation, particularly rotation, the first actuating part 70, the main unit 50, particularly its plunger rod 51, moves axially, particularly by pushing, (further) through the bottom 22F of the frame 22 and / or (further) through the second end 83 of the second actuating part 80 and / or the hole 83C and / or the frame 83B.

[0348] Best of all Figure 7 As shown, during actuation of the first actuation part 70 and / or at least between the initial position and the release position and / or during startup, the return lock of the actuation mechanism is preferably activated and / or the return stop 24 of the frame 20 preferably engages (axially) the return stop 51E of the main unit 50.

[0349] Therefore, during the actuation of the first actuation portion 70 and / or at least between the initial position and the release position and / or during startup, the rearward movement of the main unit 50, i.e., the movement of the main unit 50 in the direction away from the container 10 and / or toward the first actuation portion 70, is preferably prevented or at least restricted due to the rotary lock.

[0350] Best of all Figure 8 As shown, the position and / or rotation angle of the second actuating portion 80 are preferably (still) at least substantially fixed and / or restricted in the released position by means of the frame 83B, particularly the locking element 83E and / or the blocking element 83D, which engage / abut against the main unit 50, particularly the plunger rod 51, from both sides (radially). Figure 8 From below and above.

[0351] Preferably, the second actuation portion 80, particularly the blocking element 83D of the second actuation portion 80, is axially spaced from and / or not axially engaged with / blocks the main unit 50, particularly the plunger rod 51, from the first stop 51C of the main unit 50, most preferably in the initial position / state and / or the release position and / or throughout the start-up process.

[0352] Preferably, the second actuating portion 80, particularly the blocking element 83D of the second actuating portion 80, axially engages / blocks the main unit 50, particularly the plunger rod 51, only after the start-up and / or feeding is completed and / or only in the feeding position / state and / or in the final position / state, as will be referred to below. Figure 9 and Figure 10 as well as Figure 11 and Figure 12 As stated above.

[0353] Figure 9 and Figure 10 The feeding device 100 is shown in the feeding position, i.e., after the drive spring 60 has been partially released and / or after startup is complete.

[0354] The feeding position is preferably the (axial) position of the main unit 50, the stop 18 and / or the starter 90 relative to the frame 20 and / or the container 10, (immediately) after the start-up process is completed and / or (immediately) after (full) start-up, particularly after rotating the first start-up part 70 and / or (immediately) before feeding and / or during the feeding state of the feeding device 100.

[0355] In the feeding state of the feeding device 100, the first actuation part 70 is fully actuated while the second actuation part 80 is not actuated.

[0356] In particular, during the delivery state of the delivery device 100, the second actuation part 80 can be (directly) actuated, especially by pressing, and / or can deliver fluid 11 to the patient without performing any other steps other than actuating the second actuation part 80.

[0357] As already mentioned, the drive spring 60 preferably moves, in particular, to push the first starter portion 91 and the second starter portion 92 apart from each other.

[0358] After reaching the release position, by means of the drive spring 60, the second actuator section 92 / main unit 50 moves relative to, in particular, the first actuator section 91 and / or toward the container 10, into the feeding position / state.

[0359] Therefore, in the feed position / state, compared to the initial position / state and / or the release position, the drive spring 60 is preferably less stretched / compressed and / or further extended and / or the spring chamber 93 is longer / less compressed.

[0360] In the feed position / state, compared with the initial position / state and / or the release position, the length of the drive spring 60 and / or the spring chamber 93 increases, preferably by at least 0.1 mm or 0.3 mm and / or at most 2 mm or 1 mm, especially by at least substantially 0.5 mm.

[0361] Preferably, the length of the drive spring 60 and / or spring chamber 93 in the feed position / state corresponds to the second and / or intermediate length L2 (see...). Figure 9 Preferably, the second / intermediate length L2 is greater than the first / minimum length L1, and preferably greater than... Figure 9 The difference shown is X1 and / or at least 0.1 mm or 0.3 mm and / or at most 2 mm or 1 mm, particularly at least substantially 0.5 mm.

[0362] In other words, when / after reaching the release position, the drive spring 60 preferably pushes the main unit 50, in particular the plunger rod 51, further into the container 10, preferably by at least 0.1 mm or 0.3 mm and / or at most 2 mm or 1 mm, particularly at least substantially 0.5 mm, and / or until the main unit 50, in particular the plunger rod 51, most preferably the first stop 51C, (axially) abuts / impacts the frame 83B and / or the blocking element 83D of the second actuation part 80, but... Figure 10 As can be seen in the text.

[0363] Therefore, it is preferred that, in the feeding position, the second actuation portion 80, in particular the frame 83B and / or the blocking element 83D of the second actuation portion 80, engages (axially) the main unit 50, in particular the plunger rod 51, most preferably its first stop 51C, thereby preventing the main unit 50 from moving further into the container 10.

[0364] The further release / extension of the drive spring 60 / its spring force / energy, and / or the movement of the main unit 50, in particular the plunger rod 51, into the container 10 is prevented by means of the second actuation portion 80, in particular the frame 83B of the second actuation portion 80 and / or the blocking element 83D, which axially and / or form-fits the main unit 50, in particular the plunger rod 51, most preferably its first stop 51C.

[0365] As already mentioned, the second actuation part 80 can be directly actuated in the feed position / state.

[0366] Preferably, due to the (stepped) rear section 51B of the plunger rod 51, in the feed position / state, the locking element 83E of the second actuation portion 80 preferably no longer (radially) engages / abuts against the plunger rod 51.

[0367] Preferably, the frame 83B and / or locking element 83E of the second actuation part 80 and the plunger rod 51 of the main unit 50, particularly its rear section 51B, are radially spaced apart from each other, so that in the feed position / state, the second actuation part 80, particularly its button 84, can be actuated, particularly pressed, preferably as follows: Figure 10As shown in the image.

[0368] In other words, in the feed position / state, the plunger rod 51 preferably does not obstruct the second actuation part 80 from being actuated, in particular, pressed.

[0369] By actuating the second actuation part 80, particularly by pressing the button 84, the delivery of fluid 11 can be performed and / or the main unit 50 and / or the stop 18 can be moved to the final position.

[0370] By actuating, particularly by pressing the second actuating portion 80, especially its button 84, the second actuating portion 80, especially its second end 83, pivots about the pivot axis P and / or moves at least substantially relative to and / or away from the main unit 50, in particular causing the blocking element 83D (axially) to disengage from the main unit 50, especially its first stop 51C, and / or causing the drive spring 60 / its spring force / energy to be (again) released and / or to (further) extend and / or move the main unit 50, especially its plunger rod 51, further into the container 10.

[0371] The second actuating portion 80 can be actuated, in particular pressed, preferably until the locking element 83E (again) radially abuts / engages the main unit 50, in particular the plunger rod 51. Thus, in the final position / state, the locking element 83E preferably (again) radially abuts / engages the main unit 50, in particular the plunger rod 51, thereby particularly preventing further pressing of the second actuating portion 80.

[0372] Figure 11 and Figure 12 The feeding device 100 is shown in its final position / state, i.e., after the actuation of the second actuation part 80.

[0373] The final position is preferably the (immediate) position of the main unit 50 and / or the stop 18 relative to the frame 20 and / or the container 10 after feeding and / or after (fully) actuating the second actuation part 80 and / or in the final state of the feeding device 100 (axial).

[0374] When the feeding device 100 is in its final state and / or when the main unit 50 and / or the stop 18 are in their final positions, the feeding of fluid 11 has been performed, the second actuation part 80 is (fully) actuated and / or the drive spring 60 is at least partially (further) released.

[0375] In the final state / position, compared with the initial state / position and / or the feeding state / position, the main unit 50, the stop 18 and / or the second actuator portion 92 are arranged closer to the outlet of the feeding device 100 and / or further away from the first actuation portion 70 and / or the first actuator portion 91 and / or further inserted into the container 10.

[0376] In the final position / state, compared with the delivery state / position, the second starter section 92 / main unit 50 is preferably moved further by means of the drive spring 60, in particular being pushed out of the first starter section 91.

[0377] In the final position / state, compared to the initial position / state and / or the feed position / state, the drive spring 60 is less stretched / compressed and / or further extended and / or the spring chamber 93 is longer / less compressed.

[0378] In the final position / state, compared to the feed position / state, the length of the drive spring 60 and / or spring chamber 93 is (further) increased, preferably by at least 1 mm or 2 mm and / or at most 10 mm or 8 mm, particularly by at least substantially 5 mm.

[0379] Preferably, the length of the drive spring 60 and / or spring chamber 93 in the final position / state corresponds to the third and / or final length L3 (see...). Figure 11 Preferably, the third / final length L3 is greater than the first / minimum length L1 and / or the second / intermediate length L2, preferably as follows: Figure 11 The difference shown is X2 and / or at least 1 mm or 2 mm and / or at most 10 mm or 8 mm, especially at least substantially 5 mm.

[0380] In other words, when the second actuation part 80 is actuated, the drive spring 60 preferably pushes the main unit 50, in particular the plunger rod 51, further into the container 10, preferably by at least 1 mm or 2 mm and / or at most 10 mm or 8 mm, in particular at least substantially 5 mm, and / or until the main unit 50, in particular the plunger rod 51, most preferably the second stop 51D, abuts / impacts the frame 83B and / or the blocking element 83D of the second actuation part 80, thereby preventing the main unit 50 from moving further into the container 10.

[0381] Therefore, according to one aspect of the invention, the drive spring 60 / its spring force / energy is at least partially extended / released by actuation, particularly rotation of the first actuation portion 70, and at least partially extended / released by actuation, particularly pressing of the second actuation portion 80.

[0382] Therefore, the energy stored in the preloaded drive spring 60 is preferably released in two steps and / or by actuating the first actuation part 70 and subsequently actuating the second actuation part 80.

[0383] In this way, the availability of the feeding device 100 is improved and the transition from the initial state / position to the feeding state / position and the final state / position is facilitated.

[0384] According to another aspect of the invention, the axial movement of the main unit 50 is restricted in both the feeding position / state and the final position / state by means of the second actuation portion 80, in particular the blocking element 83D.

[0385] Using the (same) blocking element 83D to stop the axial movement of the main unit 50 after startup and delivery improves dosing accuracy and thus minimizes the need for dosing in the manufacturing process.

[0386] In the final position / state, the position and / or rotation angle of the second actuating portion 80 are preferably (again) at least substantially fixed and / or limited by means of a frame 83B that engages / abuts the main unit 50, particularly the plunger rod 51, from both sides. Figure 12 From below and above.

[0387] In particular, in the final state / position, the position and / or rotation angle of the second actuating portion 80 are preferably at least substantially fixed and / or restricted by means of a locking element 83E that engages / abuts from one side of the main unit 50, particularly the plunger rod 51. Figure 12 From below, and by means of a blocking element 83D that engages / abuts the main unit 50, particularly the plunger rod 51, from the other side, in Figure 12 Viewed from above.

[0388] Now refer to Figures 13 to 15 This will describe the mechanical interaction between the main unit 50 and the indicator section 40.

[0389] Figure 13 This is a partial perspective view of the feeding device 100 in its initial state. Figure 14 This is a partial perspective view of the feeding device 100 in the feeding state. Figure 15 This is a partial perspective view of the feeding device 100 in its final state.

[0390] As already mentioned, the main unit 50, particularly its intermediate portion 52, preferably has pins 52A / 52B that preferably protrude radially into and / or axially engage with the indicator portion 40, particularly its axial openings 41A / 41B and / or spiral grooves / surfaces 42A / 42B, preferably only after reaching the feed position / state and / or during movement from the feed position / state to the final position / state.

[0391] The axial movement of the main unit 50, particularly its pins 52A / 52B, is most preferably at the feed position, and thus preferably causes rotation of the indicator portion 40, particularly about and / or relative to the main unit 50, especially its intermediate portion 52. In this way, the rotation angle of the indicator portion 40 is related to the axial position of the main unit 50.

[0392] Preferably, the indicating device of the main unit 50, particularly the pins 52A / 52B, and the indicating portion 40, particularly its indicating device 43, are both visible from the outside and / or through the housing window 36.

[0393] Preferably, the indicating device of the main unit 50, particularly pins 52A / 52B, is axially movable, preferably within the elongated sleeve window 36, particularly from one end of the sleeve window 36 to the other. Figures 13 to 15 From top to bottom.

[0394] The position of the indicating device of the main unit 50, particularly the pins 52A / 52B, within the housing window 36, directly indicates the axial position of the main unit 50 and / or the stop 18, particularly the initial position, release position, feed position, and / or final position.

[0395] The housing 30, particularly the housing window 36, may be equipped with labels, markings, etc., corresponding to the initial position, release position, feed position, and / or final position, so that the indicating device of the main unit 50, particularly the pins 52A / 52B, indicates the position of the main unit 50 and / or the stop 18 relative to the labels, markings, etc.

[0396] The indicator portion 40, in particular its indicator device 43, is preferably moved substantially laterally relative to the longitudinal extension of the (elongated) housing window 36, thereby preferably indicating the state of the feeding device 100 and / or the axial position of the main unit 50 and / or the stop 18, in particular the initial position, release position, feeding position and / or final position.

[0397] Most preferably, the indicator portion 40, in particular its indicator device 43, is adapted to indicate the state of the feeding device 100 and / or the axial position of the main unit 50 and / or the stop 18, especially when the final state / position is reached.

[0398] In this embodiment, the indicator 43 is implemented as an elongated marker, preferably with a contrasting color, which moves substantially laterally into the housing window 36 when the final position / state is reached.

[0399] In this way, availability is improved and / or the risk of misuse due to possible misunderstanding of the status of the feeding device 100 is reduced.

[0400] Furthermore, the indicator section 40 restricts visibility into the feeding device 100, particularly through the housing window 36, thereby drawing the user's / employer's attention to the indicator section 40 and / or the indicator device of the main unit 50, especially its pins 52A / 52B.

[0401] A preferred method for operating the feeding device 100 preferably includes at least one of the following steps:

[0402] (Manually) actuated, in particular, by rotating the first actuating part 70, thereby axially moving the main unit 50, the stop 18, the drive spring 60, and / or the actuator 90 relative to the shelf 20 and / or container 10, particularly by means of the lead screw of the actuation mechanism, most preferably by means of the interaction between the thread 94 of the actuator 90 and the thread 76 of the first actuating part 70, and / or

[0403] (Manually) actuating, particularly rotating, the first actuating portion 70, particularly until reaching the release position of the main unit 50, thereby releasing the second actuator portion 92, particularly its threaded portion 92E, and / or partially extending / releasing the drive spring 60 / its spring force, particularly causing the first actuator portion 91 and the second actuator portion 92 to move apart from each other by means of the drive spring 60, and / or causing the actuation end to be completed automatically and / or by means of the spring force / energy of the drive spring 60, and / or

[0404] (Manually) actuating, in particular pressing, the second actuation part 80, especially its button 84, thereby (axially) disengaging the blocking element 83D of the second actuation part 80 from the main unit 50 and / or (again) at least partially (further) extending / releasing the drive spring 60 / its spring force, in particular causing the main unit 50 and / or the stop 18 to move automatically and / or by means of the spring force / energy of the drive spring 60 from the feed position to the final position.

[0405] As already mentioned, the delivery device 100 can be adapted for ophthalmic injections. In one embodiment, the delivery device 100 is adapted for ophthalmic injections and therefore has a suitably small volume.

[0406] The feeding device 100, particularly the container 10, may also be silicone-free, or substantially silicone-free, or may include a low level of silicone as a lubricant. In one embodiment, the feeding device 100 and / or container 10 may meet the requirements of USP789.

[0407] The delivery device 100, particularly the container 10, can be filled with any suitable injectable fluid / liquid / drug 11.

[0408] In one embodiment, the delivery device 100, particularly the container 10, is filled with a fluid 11, particularly an injectable drug comprising an active ingredient suitable for treating an eye disease.
