task The invention is an apparatus and a method of administration to provide an injectable product to a user The device allows different states of the device to one easy to recognize.
The Task is solved by the characteristics of the independent Claims. Advantageous developments emerge from the dependent claims.
at the device according to the invention for administering an injectable product may be a Injection device, preferably around an autoinjector or Injektionspen act. The administration of the injectable product may be at a device according to the invention, especially in an autoinjector comprise several sequences. For example, you can a puncture sequence in which a needle is inserted into a body tissue is stabbed, and a Ausschüttsequenz in which the Example liquid Drug is distributed, be provided. Advantageously, the Ausschüttsequenz or preferably the Einstechsequenz in which followed by a Ausschüttsequenz can be activated. The device may comprise a housing, which, for example, comprises two or more housing parts which are detachable or non-detachable with each other connectable or connected. This includes, inter alia, a screw, Bayonet or snap lock in question. A mechanical sequence control, which controls the puncture and / or Ausschüttsequenz can, for Example in a proximal housing part and a product container in a distal housing part be included or become. Under "proximal" is the opposite of the needle Side and under "distal" the at the needle lying side of the particular elongated injection device Understood. The product container, in particular an ampoule, can in the distal housing part be used interchangeably or directly from the distal housing part be formed. The housing can also be formed in one piece.
The housing has a housing wall. On the housing, in particular and the housing wall a see-through element is formed. The see-through element is used by a user of the device to move from the outside through the housing wall into the interior to look at the case. This area is referred to as the visual area below. In particular, the viewing area may be a projection of the see-through element in the radial direction to the longitudinal axis of the device. By "within the field of view" is meant also elements which are within the projection of the see-through element but, for example, because it obscures another part through which the see-through element is not visible. The see-through element may be a window or opening in the housing wall. In particular, the see-through element may also be a part of a transparent material formed by the housing wall or inserted into the housing wall. Preferably, the transparent material may be glass or a clear or colorless plastic. In preferred embodiments, the see-through element may have an enlarging or reducing optical effect. For this purpose, the see-through element may be a lens or the like.
The Device has a particular mechanical discharge display on that inside the case relative to the housing at least partially movable through the field of view and at least regional and dependent be seen by the switching state of the device by the user can. Preferably, the dispensing indicator is in the longitudinal direction the device movable. The dispensing indicator is used to the To give information to users whether the product or how much of distributed to the product has been. The product is preferably in a product container which contained in the device or can be inserted into the device. The product can be made from a piston acting on the product the product container distributable be. Preferably leads the piston in the product distribution a movement relative to the product container. Piston and dispensing indicator can be coupled with each other so that when moving from one from dispense indicator and piston the other the movement of the one at least partially participates. For example, the one in the movement of a particular Take the path, with the other going a long way, the bigger one or is less than or equal in size like the other's. For example, the one with a moving at a certain speed that is greater or less than or equal to the speed of the other. Preferably, the one leads in the movement the same direction as the other. Particularly preferred at the discharge movement the piston around a bigger way moved as the dispensing indicator. In particular, the piston may be a part of its zurückzulegenden for a complete distribution So go back, that the movement of the piston in this section completely from the dispensing indicator is decoupled. While the piston in the section moves, for example, no force is on the payload display works, changes. Preferably, no force acts on the dispensing indicator, while the piston is in the section emotional. It is generally preferred that the dispensing indicator relative to the housing stands still when the piston is moved in the section.
Especially the piston, when he has covered the section, in which his Movement from the dispense indicator is decoupled, a residual path for the product distribution return, wherein the movement of the piston is coupled to the dispensing indicator. The Coupling may be, for example, the way that the dispensing indicator Follow the movement of the piston. Preferably, the dispensing indicator sets the same way back, like the piston in the way out. It is particularly preferred that the dispense indicator is moved at the same speed as the piston when going through the rest way.
The Ausschüttanzeige can depend on the Piston position with a certain range in the field of vision be located and / or in particular be behold. There can be several Areas at the dispense indicator be provided. In several areas, these can move one behind the other in the direction of movement be arranged so that when moving through the field of view different areas go through the field of view. Preferably each area has a different information than the other areas or an adjacent area. This allows the user of the device based on the information at a given moment under the Review screen appears, detect if or how much product from the product container distributed has been.
For example may be a first area in the field of view, in the product distribution is moved out of sight so that another, such as a second area is in the field of view when the product has been completely spilled. Between the first area and the second area can be an intermediate area be arranged, which is during the product distribution located in the field of view or moved through the field of view, and can be seen. This allows the user of the device realize that the product distribution has already begun, but is not yet complete, since For example, this would only be the case if the second area would be in the field of vision.
The information of the areas may in particular be a material property, a character, an image and / or a color information, wherein at least the information of the first area is different from the one distinguishing between the second range. The information of the first area may be similar, such as different letters. The information may also be diverse, such that, for example, the first area has a letter and the second area has color information. The material property may be, for example, the type of material used or a surface texture. A character may be, for example, a letter, a symbol or the like. For example, a color information can be a color that is meaningful for the respective ejection state. By way of example only, the first region may have a less noticeable color, such as "green," and the second region may have a distinctive color or signal color, such as "red." The user of the device will initially perceive the less noticeable color through the see-through element. As product dispensing progresses, the user of the device can see through the see-through element the area of signal color that moves into the field of view. For example, to give the user of the device information that the device is still in the product distribution sequence, an intermediate region may be arranged between the first region and the second region, containing both information of the first region and information of the second region can have. Alternatively, the intermediate area may also have its own information that is different or different or similar from the information of the first and / or the second area. For example, the intermediate area may have predominantly color information of the adjacent area at approximately the point where it adjoins the adjacent area. Preferably, since the information of the first and second areas are different, in the intermediate area, the color information of the first area may change from the first area in the course to the second area into the color information of the second area. The change of the color information may for example be homogeneous, so that in the intermediate area there are a multiplicity of colors perceptible to the human eye, or the colors are mixed. The change in the color information can also be inhomogeneous, with fields preferably having, for example, two fields with different colors whose respective width or area proportions increase or decrease. For example, the intermediate area may include the colors of the first and second areas. For example, the proportion of the color of the first region in the course from the first to the second region may decrease and the proportion of the color of the second region may increase. Preferably, the color of the second region in the course from the first region to the second region increases as the color of the first region decreases in the course from the first region to the second region.
The The device further comprises a visual release member, with which the view blended to the dispensing indicator can be. "The Fade view "means that the View of the dispensing indicator can be blocked so that the dispensing indicator is not recognizable, or that the view of the dispensing indicator, for example, via a transparent Material possible is, but in the direction behind the visual release part with a certain information of the visual release link becomes. For example, the information may be a particular coloration of the transparent material or sign or a letter or a Be image information, the / on the transparent or opaque Sight release is applied.

The needle may be slidable relative to the housing along its longitudinal axis. The needle is preferably surrounded by the housing or a needle protection sleeve arranged on the housing in such a way that the needle can emerge distally from the housing or the needle protection sleeve for insertion, for example by a certain puncturing length. The needle may be coupled to the visual release member such that upon movement of one of the visual release member and the needle, the other at least partially participates in the movement of the one. Preferably, the visual release member may be in the same direction and / or in move about the same way and / or at the same speed as the needle during piercing. The needle can be mounted relative to the container movable or axially fixed to the container, in particular directly to the container, so that the needle and container can perform a common piercing movement. The embodiments for the coupling of the needle with the visual release member preferably apply correspondingly for the coupling of the Sichtfreigabeglieds with the container.
The Needle and / or the product container may be relative to the housing along the longitudinal axis displaceable between a starting position and a piercing position be. In the starting position, the device is in the "resting state", ie before a release the distribution and plunge sequence. In particular, the needle is there inside the case or the needle guard. In the puncture position, the needle is distally out of the housing or the needle protection sleeve with a desired plunge emerged. The needle / product container passes through into the puncture position Trigger the Einstechsequenz in the starting position.
The Visual release member preferably has a first area, which is in the field of view when the product container is in his or her needle is in its starting position. To the For example, the first area may contain information that can be seen through the see-through element. Based on this information the user of the device can visually determine that the Needle has not yet pierced or the device is in her Home position is located. The information of the first area can For example, a material property of the material of the first area Be a character, an image and / or a color information. Especially can the information be similar the information of the first or the second area of the discharge display be. In preferred embodiments the first area is transparent or opaque. Unless the first area is opaque, is in the line of sight the view behind the visual release link not possible. at a transparent first area of the visual disclosure member is the View in the direction behind the sight release member possible. Especially the first area may be clear or colorless, or one with one have certain color provided transparency. In addition, can another information arranged on the surface of the first area be, which is particularly preferred in a transparent first area is.

This has the advantage that the Users of the device can visually recognize when the needle with the desired penetration length out of the case or the needle guard has emerged or pierced into the body tissue. Particularly preferably, the user can, for example, by the see-through element and the second portion of the visual release member the dispensing indicator read off. For example, the second area of the visual release member smaller, bigger or about the same size as that Be see-through element. In particular, the second area of the Sichtfreigabeglieds have approximately the shape of the see-through element.
Especially the second area can connect to the visual release link or to be a window in the visual release link. The second area can, but does not have to be an integral part of the visual disclosure. For example the visual release member may be terminated proximal to the first region, so that upon movement of the needle or container from the starting position into the puncture position, the visual release member or the first area from the field of view, for example, essentially Completely is moved. The area that is proximal to the visual release link connects, can therefore be referred to as the second area, in particular and generally in the second area the view of the distribution is functionally released becomes.
In another embodiment the second area may be element of the visual release element. Of the second area can then be a window or a transparent one Material be formed. Preferably, in a transparent second area the material clear or colorless transparent. Generally preferred is, however, that in a transparent first area, the transparent Material of the second area has a different color than the transparent Material of the first area. Thus, the user of the device easy and safe to recognize when the needle is at its puncture position located.

At the proximal end of the output member 8th There is a radially outwardly standing collar 8b , Between output element 8th and the feed element 9 There is an annular groove whose groove width is greater than the amount that the collar 8b radially from the output member 8th projects. For the formation of the annular groove, for the storage of the output member 8th and for the movement of the dispensing indicator 4 picks up the dispensing indicator 4 with a sleeve-shaped portion from the distal side into the inner diameter of the advancing element 9 and surrounds the output member 8th ,
The distal end of the output member 8th has an end face acting as a stop surface 8a on, on which a spring 15 , in particular a coil spring can support. The pressure-preloaded spring 15 is supported at its other end on a distal surface of a stop element, which at a proximal portion of the advancing element 9 is formed. The feather 15 which, in particular, has a larger spring constant than the spring 14 can have, the output member 8th when released, drive in the distal direction along the longitudinal axis. The distal end of the output member 8th comes with a piston rod 7 or with one at the proximal end of the piston rod 7 arranged dome-shaped element in contact, whereby the distal to the piston rod 7 arranged pistons 7a in the product container, causing the product through the needle 6 is distributed when the output member 8th is moved in the distal direction.
At the proximal end of the advancing element 9 is a relative to the advancing element 9 along the longitudinal axis movable locking element 12 arranged. The locking element 12 is forked and engages around the longitudinal axis with two locking portions 12A , The locking portions are each in a groove-shaped guide, that of the feed element 9 is formed, led. The locking element 12 is from a spring 13 subjected to a force in the distal direction. The feather 13 rests against the proximal end of the locking element 12 and at a proximally disposed therefrom feed element fixed element, namely on a holding web. The feather 13 may be, for example, a helical or combined helical and spiral spring or a leaf spring. For example, the retaining bar may be made of a spring material and have a shape that the locking element 12 can act directly on a spring force, so that the spring 13 Can be omitted because the locking element 12 the task of the spring 13 takes over.
A movement of the locking element in the distal direction is in particular prevented by the fact that the locking element 12 with its locking sections 12A from the collar 8b of the output member 8th is blocked. The collar 8b In turn, the cam-shaped locking elements 9b , each one on one arm 9b arranged and resilient with the feed element 9 , in particular are integrally connected, prevented from moving in the distal direction.
The housing wall 1 of the proximal housing part 18b has a see-through element 2 on, which is designed as a window. Through the see-through element 2 For example, the viewer may look in the direction of the device from outside the device. In the 1A to 3B The look becomes inside the device through the visual release link 3 blocked. The visual release link 3 has a first area 3a on, in the starting position of the device, namely before the puncture and Ausschüttsequenz, in the longitudinal direction of the device at the same height with the see-through element 2 located. As well as in 7 is shown, the first area indicates 3a a first information, which is shown in the form of a hatched area. Similarly, the information could be in a particular color, such as red, or with the aid of a character or letter (not shown). Based on this information of the first area 3a the user of the device can recognize that no product distribution or no piercing process has taken place yet. Will, as in 4A and 4B is shown, the released feed element 9 moves in the distal direction, the blocking element passes 9b after a certain distance, which preferably corresponds approximately to the path to the product container 5 is moved to the piercing, approximately at the same axial height as a locking groove 10a , The locking groove 10a gets from the mechanics holder 10 educated. The locking groove 10a can for the blocking elements 9b each be a depression or an annular circumferential recess. Once, as in 4A is shown, the locking groove 10a and the blocking element 9b are at an axially equal height, due to the spring force of the arms 9a and / or the spring force of the spring 13 and / or due to the spring force of the spring 15 in connection with the slipping of the collar 8b radially outward into the locking groove 10a emotional. This starts the ejection sequence.
During the plunge sequence, at driven by the spring 14 , on the one hand, the output member 8th with its preloaded drive spring 15 and on the other hand the visual release link 3 and the dispensing indicator 4 taken. The visual release link 3 in turn takes the product container 5 together with the needle attached to its distal end 6 for a piercing movement with. This will be the first area 3a of the visual disclosure member 3 out of the field of view of the see-through element 2 moves, creating, first, an intermediate area 3c of the visual disclosure member 3 as he is, for example, in 7 is displayed in the field of view of the see-through element 2 what the user of the device can see that the needle 6 during the piercing sequence. When the piercing position is reached, the second area moves 3b of the visual disclosure member 3 , the first of the housing wall 1 was covered in the field of view of the see-through element 2 , The second area is formed in the shape of a window. Because the dispensing indicator 4 together with the visual release link 3 during the piercing sequence is moved in the distal direction, the user of the device through the see-through element 2 and the second area 3b of the visual disclosure member 3 on the discharge display 4 look. Before a product is distributed, the distribution indicator is located 4 with a first area 4a at the axial level with the second area 3b of the visual disclosure member 3 , The user can therefore at the end of the Einstechsequenz or at the beginning of the Ausschüttsequenz the information of the first area 4a the dispense indicator 4 read off. As in 8th can be represented, the first area 4a contain information which, as illustrated herein, may consist of a hatched area or, in particular, may consist of a particular coloration such as "yellow". By the change in the see-through element 2 appearing color recognizes the user the changed operating state of the device.
Referring to the dispensing indicator 4 can, deviating from the in the 1A to 6B shown design, the discharge display 4 be extended in the distal and / or proximal direction. For a proximal extension of the dispensing indicator 4 is preferably the second area 4b at or on the proximal extension. For a distal extension of the dispensing indicator 4 is preferably the first area 4a at or on the distal extension.
After started Ausschüttsequenz the collar 8b from the blocking element 9b no longer blocked, causing the spring 15 the output member 8th in the distal direction and thus the piston 7a over the piston rod 7 for a product distribution. At the same time the locking element 12 released for axial movement, leaving the spring 13 the locking element 12 so far shifts that the locking sections 12a in front of the blocking element 9b slide. A movement of the locking elements 9b from the locking groove 10a is prevented because the locking sections 12a the movement that the blocking element 9b during a movement out of the locking groove 10a would execute, blocked. Thus, the feed element 9 axially fixed to the housing. During the movement of the output element 8th The output element takes the path z 8th initially only the piston rod 7 with that the piston 7a also moved about the way z. The dispensing indicator 4 is traversed while the path is z, not yet moved. After passing through the path z of the radially projecting collar 8b of the output member 8th in an axial stop with a stop 4b extending proximally of the sleeve-shaped portion of the dispensing indicator 4 located. Due to the driving force of the spring 15 and the collar 8b becomes the dispensing indicator 4 on the remaining way, which corresponds to the total stroke of the piston minus about the way z, carried along until the piston 7a the product completely out of the product container 5 has displaced. During the product dispensing sequence, the dispensing indicator becomes 4 , in particular its first area 4a moved out of sight. Because the dispensing indicator 4 no second area 4b but it is the second area 4b proximal to the dispensing indicator 4 joins, will, as in the 5A and 6A shown as information for a successful product distribution the look below the dispense indication 4 Approved.
Alternatively, at one with a discharge display 4 according to 8th designed injection device during the Produktausschüttsequenz the first area 4a the dispense indicator 4 out of the field of view of the see-through element 2 moved in the distal direction. This is initially an intermediate area 4c moved into the field of view, where the user of the device recognizes that the Produktausschüttsequenz has begun, but is not yet completed. Upon reaching the end position of the piston, the area 4b in the field of view of the see-through element 2 moves the user to recognize that the product distribution has ended.
Referring to 8th is the information that the area 4b has, symbolically represented with a hatched area. For example, the area 4b have a "green" color. In the intermediate area 4c are both the information of the first area 4a , as well as the information of the second area 4b , With progressing approach in the intermediate area from the first area 4a to the second area 4b takes the information of the first area 4a from and the second area 4b to. Thus, the user of the device based on how far the Zwischenbe rich 4c already moved in the longitudinal direction, estimate how far the product distribution has progressed.
It is preferred that the discharge movement of the output member 8th can only be done when the needle 6 completed her piercing movement. It is further preferred that the puncturing sequence can not be started until a transmission element configured as a needle cover 16 is pressed firmly enough at the injection site on the body tissue. When the device is pressed onto the body tissue, the transmission element becomes 16 relative to the distal housing part 18a postponed. From the proximal housing part 18b becomes a switching element 17 movably mounted along the longitudinal axis. The switching element 17 becomes during the movement of the transmission link 16 taken in the proximal direction. The transmission link 16 becomes against the force of a spring 20 and / or a spring 21 pressed in the proximal direction. The switching element 17 can be against the force of the spring 21 be moved in the proximal direction.
If, as in the 2A and 2 B is shown, the switching element 17 Moving in the proximal direction can be via the movement of a triggering element 11 in the radial direction, the switching element 17 via one on the switching element 17 arranged transmission surface (not shown) are moved even further in the proximal direction, so that, as in the 3A and 3B is shown, the locking member 10b no more of a holding level 17a of the switching element 17 is blocked. In this switching state is the locking member 10b at the axial height with a release level 17b that it's the locking member 10b allowed, from the locking engagement with the feed element 9 to arrive, whereby the Einstechsequenz is started. The feed element 9 For example, it may have one or more annular depressions, for example, in which the locking member 10b for the locking engagement with the feed element 9 can intervene.
As in the 6A and 6B is shown, after piercing and Ausschüttsequenz have taken place when removing the injection device, the needle cover 16 from a return spring 21 so far in the distal direction over the needle 6 pressed that needle 6 completely disappears in the device. This reduces a risk of injury to the user of the device. At the same time, the switching element 17 after the trigger element 11 moves back to its original position and the switching element 17 released from the spring 21 in his for example in the 1A and 1B moved back starting position shown. Unlike the starting position, (for example 1A ) recognizes the user based on the changed information under the see-through element 2 in that the device has already been used.
