Definitions
- the present invention relates to an apparatus for opening an ampoule.
- the device has a housing for receiving an ampoule and is designed to break off the ampoule head from the ampoule body.
- Ampoules are often used, especially in medicine and chemistry, to store fluid products such as drugs or aggressive substances such as monomers, sterile and protected against diffusion.
- Commercially available ampoules are usually made of glass and have a completely sealed to the outside interior, in which the fluid product is stored.
- Such ampoules are usually elongated and comprise an ampoule head and an ampoule body, which are connected to each other via a tapered neck of the ampoule.
- the ampoule head in the region of the ampoule neck which forms a predetermined breaking point, is broken off from the ampoule body, so that the fluid product can be removed from the ampoule.
- Such devices are for opening one or more ampoules for example, in the documents US 6,296,149 and US 5,335,824, in which the ampoules are each housed in a housing comprising two housing parts.
- the two housing parts are each rotatable relative to each other about an axis of rotation, and the ampoules are arranged eccentrically to this axis of rotation in the housing, that a rotation of the two housing parts causes a lateral shearing force on the ampoule head. Due to the eccentric arranged to the axis of rotation vials, these devices have a relatively large amount of space.
- the document WO 97/07748 discloses a device in which the ampoule body is held in a housing, and in which the ampoule head protrudes into an ampoule head receptacle.
- The> ampoule head is separated by rotating the housing about an axis of rotation perpendicular to the longitudinal axis of the ampule relative to the ampoule head receptacle.
- the device is complicated and expensive to manufacture.
- the device should also have a simple handling and a simple and compact design.
- the present invention thus provides a device for opening an ampoule, in particular a glass ampoule, having an ampoule body and an ampoule head, comprising
- a housing having a proximal end, a distal end, and at least one sidewall substantially hollow cylindrical in shape defining a radial direction and a longitudinal axis extending from the proximal end to the distal end, and having an interior for receiving one Ampul limited in the radial direction, and
- At least one rotary element having a proximal region, with which a break-off region extending in the distal direction is connected, which is designed to be flexible in the radial direction and / or is pivotably connected in the radial direction to the proximal region.
- the rotary member is rotatable relative to the housing in an actuating direction from an initial position to an intermediate position about the longitudinal axis.
- the housing also has, in the region of the side wall, a first guide structure, which is designed such that it presses the break-off region inward in the radial direction during a rotation from the initial position into the intermediate position, so that the break-off region applies a radial shearing force to the ampoule head of FIG in the interior taken ampoule to separate the ampoule head from the ampoule body.
- the torque generated by the user is converted into a radial shear force acting perpendicular to the longitudinal axis of the ampule.
- the shearing force optimally acts from the side on the ampoule head, ie from a direction perpendicular to the longitudinal axis of the ampoule.
- a leverage effect is achieved, which reduces the force required to separate the ampoule head force.
- the force required to break up the ampoule is minimized by this configuration of the device.
- the ampoule usually has a radially tapered neck region, which forms a predetermined breaking point.
- the neck area is arranged between the ampoule body and the ampoule head.
- the ampoule can be incised peripherally or unilaterally on its outside to produce a predetermined breaking point.
- the ampoule head is separated from the ampoule body in such a way that the ampoule head is not yet smashed, but remains substantially intact. The fragmentation of the ampoule head can then be done by a later process.
- the housing as a whole is substantially hollow-cylindrical, in particular substantially circularly hollow-cylindrical.
- the housing At the distal end of the housing is preferably a Austrittsöf hung available, which can be closed with a liquid-permeable filter element. At the proximal end, the rotary element is preferably sealed against the housing.
- the housing is used in particular for receiving the fluid product contained in the ampoule after breaking off the ampoule head. It also serves as a transport lock for the fragile ampoule.
- the angular range which the rotary element travels relative to the housing from the initial position to the intermediate position is preferably less than 90 °.
- the break-off region can be connected directly or indirectly to the proximal region of the rotary element.
- a push-in opening is preferably formed, through which the ampoule and the rotary element can be inserted into the interior.
- the rotary element preferably has a sleeve-like region which extends into the interior space and surrounds the ampoule circumferentially in the inserted state.
- a circumferential sealing element is advantageously mounted, which seals the rotary element and the housing against each other in a fluid-tight manner.
- the rotary member also preferably has a top surface which closes the Einschieböffhung.
- the rotary member advantageously has a user-accessible proximal operating handle, by means of which the rotary member relative to the housing for the User is rotatable.
- the first guide structure can in particular be realized such that it has a substantially radially towards the interior facing guide surface which approximates in the circumferential direction of the longitudinal axis such that they increase the break-off region during a rotational movement of the rotary member relative to the housing from the initial position to the intermediate position pushes radially inward.
- the first guide structure is formed directly on the inside of the side wall.
- the first guide structure is preferably formed by a radial recess which is arranged on the inside of the side wall.
- the housing has a first latching structure and the rotary element has a second latching structure, wherein the first latching structure cooperates with the second latching structure such that a rotational movement of the rotary element relative to the housing is possible substantially exclusively in the actuation direction.
- the first and the second latching structure thus prevent together a rotational movement of the rotary element relative to the housing against the actuating direction and thus form a one-way slip clutch.
- the rotary element Due to the fact that the rotary element is thus not reversible relative to the housing, it can be recognized by the user whether the device has already been manipulated and the ampoule has been opened or not.
- the rotary element has a fragmentation region which is designed to be flexible in the radial direction and / or is mounted pivotably in the radial direction on the proximal region of the rotary element, and to which the discontinuation region adjoins in the distal direction.
- the rotary member is then preferably rotatable relative to the housing in the actuation direction from the intermediate position to an end position, wherein the housing in the region of the side wall has a second guide structure, which is designed such that it the fragmentation region upon rotation from the intermediate position to the end position pushes in the radial direction inwards, leaving the ampoule head one in the interior taken ampoule is crushed after breaking off.
- the ampoule is thus opened in this embodiment so that the ampoule head is first separated from the ampoule body and then smashed.
- the maximum force when opening the ampoule is substantially minimized in this way, since the forces acting on the ampoule head external forces are not absorbed by an internal balance of forces from the ampoule body ,
- the smashing of the ampoule head prevents a liquid residue of the fluid product from remaining in the ampoule head.
- the separation and subsequent smashing of the ampoule head is done in a single operation, so for example by a continuous rotational movement of the rotary member relative to the housing.
- the range of rotation of the rotary element relative to the housing is advantageously limited, wherein the angular range of this limited range of rotation is preferably about 180 °.
- the Zertrürnm réelles Kunststoff of the rotary member advantageously has two or more elements, which are each arranged opposite each other in the radial direction. Accordingly, the second guide structure then also has two or more elements, which are likewise arranged opposite one another. The ampoule head is thereby compressed from at least two opposite sides and advantageously smashed into a plurality of glass chippings.
- the rotary member advantageously has a sleeve-like region, which is arranged proximally adjacent to the Zertrürnm réelles Colourungs Colour, and which has a plurality of longitudinal slots arranged opposite one another in the radial direction.
- the sleeve-like region can in particular serve to hold the ampoule body in position during the separation of the ampoule head.
- the longitudinal slots serve to increase the flexibility of the rotary member and in particular to facilitate a pressing together of the optionally present opposing elements of the fragmentation region.
- the second guide structure can in particular be realized in such a way that it has a guide surface which points essentially radially towards the interior and which extends into Circumferential direction of the longitudinal axis approximates that it presses the fragmentation region during a rotational movement of the rotary element relative to the housing from the intermediate position to the end position increasingly radially inward.
- the second guide structure is arranged proximal to the first guide structure.
- the second guide structure is formed directly on the inside of the side wall.
- the second guide structure is advantageously formed by at least one radial, projecting into the interior elevation of the side wall.
- the fragmentation area thickened radially in a direction opposite to the direction of actuation circumferential direction.
- the fragmentation region can have longitudinal grooves on its radial outer side.
- the break-off region may have longitudinal grooves on its radial outer side.
- the device may have two or more rotary elements and a housing with two or more connected side walls, each having an interior for receiving an ampoule.
- the device then also has a grip element and a force transmission structure, which has a rotational force acting on the grip element; transmits to all rotary elements, so that the ampoule heads of several ampoules are breakable by a rotational movement of the handle element.
- the force transmission structure may in particular be a gear connection between the grip element and the rotary elements.
- the gripping element can be designed as an actuating handle formed on one of the rotary elements or as a separate driving element connected to the rotary elements.
- the device may in particular be designed such that all the ampule heads break off approximately at the same time. Alternatively, however, the device may also be designed such that the ampoule heads break off one after the other while the gripping element is rotated continuously. The total force required to break off all the ampule heads is distributed in this alternative embodiment then over a plurality of rotational positions of the handle element.
- the outlet openings can be brought together in a mixing element in order to mix the various substances contained in the ampoules with one another.
- the Auseriesöffhungen can also be forwarded separately, for example, to be connected to a double or multiple syringe.

- the Luer connector 1 12 has a female cone region, on the radial outer side of a locking structure is formed. Within this female Luer cone, the outlet opening 1 13 is closed by a filter insert.
- This filter insert is designed to be permeable in particular for the fluid substance contained in the ampoule 3, but not for solid constituents, in particular glass fragments.
- the side wall 1 1 1 1 passes into an expanded portion 1 14, which in comparison to the side wall 1 1 1 has a larger outer as well as inner diameter.

- the latching elements 125 each have a stop surface which points essentially in a direction opposite to the direction of actuation.
- the locking elements 125 are formed so flexible that they are elastically movable in the radial direction inwards.
- the sleeve-shaped region 121 also has a circumferential groove 126, which is arranged proximally of the latching elements 125, and which is bounded by two radially outwardly projecting from the sleeve-shaped portion 121 flanges in the proximal and distal directions. In the groove 126, a sealing ring 13 is received.
- the sleeve-shaped region 121 is attached at its proximal end to a plate-shaped, circular cover surface 127, which closes the sleeve-shaped region 121 in the proximal direction.
- the top surface 127 has a similar radius as the edge region 1 15 of the housing 1 1 and is therefore adapted to rest on the Randberich 1 15.
- a nose 129 is formed in an area projecting outwards from the sleeve-shaped region 121. The nose 129 extends in the distal direction into the groove 16 of the housing 11.
- an actuating handle 128 extends diametrically over the cover surface 127. Markings in the form of arrows are also provided on the upper side of the cover surface 127, indicating the direction of actuation of the rotary element 12 for opening the ampoule 3 , In addition, on the radially outer side of the top surface 127, a further mark is mounted, which serves to indicate to the user, the rotational position of the rotary member 12 relative to the housing 1 1.
- the housing 1 1 and the rotary member 12 are each integrally formed in the present embodiment as a whole and made of a plastic in an injection molding process. However, both the housing 1 1 and the rotary member 12 may also be made in a multi-component injection molding or even be formed in several pieces.
- a filter insert which is present at the outlet opening 1 13, for example, a sintered layer or a perforated film can be used. In particular, the filter insert may be integrally molded onto the housing.
- the sealing ring 13 may be integrally formed with the rotary member 12 or alternatively omitted.
- Suitable materials for the rotary member 12 are, for example, due to its elastic properties polybutylene terephthalate (PBT) or polypropylene (PP).
- polycarbonate or a polyolefin-based material may be used, such as in particular polypropylene (PP) or polyethylene (PE).
- PP polypropylene
- PE polyethylene
- FIGS. 3 to 7, like FIG. 1, show the opening device 1 in one Initial position.
- the ampoule 3 is inserted into the interior of the housing 1 1 with the ampoule head 33 ahead.
- the rotary member 12 which surrounds the ampoule 3, at least in its proximal region in the radial direction fitting.
- the sealing ring 13 seals the rotary member 12 relative to the housing 1 1 circumferentially from.
- the top surface 127 of the rotary element 12 lies on the edge region 1 15 of the housing 1 1.
- the break-off area 124 is arranged in the region of the distal end of the ampoule head 33, and the break-away area 123 in that area of the ampule head 33, where the ampoule head 33 has a maximum radial extent.
- the locking elements 125 engage in the widened portion 1 14 of the housing 1 1 formed latching ridges such that the abutment surfaces of the locking element 125 are the abutment surfaces of the latching teeth opposite.
- the rotary member 12 is characterized in the actuation direction relative to the housing 1 1 rotatable, and a rotational movement against the actuating direction is prevented by abutment of the opposing abutment surfaces.
- the ampoule 3 is intact and closed in this initial position.
- the two opposing elements of the Zertrürnmanss Schemees 123 are arranged in the initial position with respect to the longitudinal direction in the region of the second guide structure 1 17, wherein the two elements of the fragmentation region 123 respectively in the circumferential direction between the two opposing protrusions 117th are arranged.
- the break-off region 124 is arranged in the initial position in the region of the first guide structure 1 19, in such a way that it is received in the recess of the side wall 1 11, which forms the first guide structure 1 19, adjacent to the actuating direction facing stop surface.
- the nose 129 with respect to the groove 16 is arranged in the circumferential direction in such a way that it forms a stop with the end face of the groove 16 which points into the actuating direction.
- the rotary member 12 is therefore rotatable from the initial position exclusively in the actuating direction relative to the housing 1 1.
- the markings affixed to the radial outer sides of the housing 1 1 and the rotary element 12 indicate to the user the initial position and thus the integrity of the ampoule 3 (FIG. 1).
- the opening device 1 is shown in an intermediate position.
- the rotary member 12 has been rotated relative to the housing 11 relative to the initial position by an angular range of slightly more than 45 ° . Due to this rotation in the direction of actuation, the break-off region 124 has been pressed radially inwards and against the ampoule head 33 by the guide surface of the first guide structure 1 19. As shown in Figure 11, the ampoule head 33 is thereby pushed away from its central position with respect to the longitudinal axis. Because at the same time the ampoule body 31 is held tightly in the sleeve-shaped region 121 and is therefore immobile in the radial direction, acts in the region of the ampoule neck 32 a radial shear force.
- This shearing force is so strong that the ampoule head 33 breaks off from the ampoule body 31 in the region of the ampoule neck 32 (FIG. 8).
- the fact that the break-off region is arranged in the region of the distal end of the ampoule head 33 he exerts an external force on the ampoule head 33, which acts in an optimal manner on the ampoule 3.
- the external force also acts on the ampoule head 33 in an optimal manner in a direction perpendicular to the longitudinal axis of the ampoule 3 from the side.
- the fragmentation region 123 is in the intermediate position with its radial outer side on the second guide structure 1 17, wherein it still exerts no significant pressure on the ampoule head 33.
- the two opposing elements of the fragmentation region 123 are pressed further radially inward on each further rotation of the rotary member 12 in the operating direction until the ampoule head 33 finally breaks. Because the ampoule head 33 has previously been separated from the ampoule body 31, a smaller force is necessary for this smashing of the ampoule head 33, since the forces acting inside the ampoule head 33 can no longer be absorbed by the ampoule body 31. As shown in FIG. 12, the fluid substance can now be drawn up into a syringe 2.
- the syringe 2 has a male luer connection 211 complementary to the female luer connection 12 of the housing 11.
- the syringe 2 has a housing 21 into which the fluid substance can be drawn by pulling out a piston 22.
- the broken glass of the smashed ampoule head 33 are held up by the attached to the outlet opening 1 13 filter insert and remain in the opening device.
- the ⁇ fmungsvoruze 1 is shown in its final position.
- the nose 129 forms a stop with the pointing in an opposite to the direction of actuation end face of the groove 1 16. Further rotation of the rotary member 12 relative to the housing 1 1 in the direction of actuation is thereby prevented.
- the AnschJagvid the first and second guide structures 1 17 and 1 19 prevent turning back of the rotary member 12 relative to the housing 1 1 against the actuation direction.
- the markings provided on the outer sides of the housing 11 and of the rotary element 12 indicate to the user the manipulation of the opening device 1 and the thus opened state of the ampoule 3.
- the housing may also be transparent, in particular in the distal region, or have a transparent window, so that the user recognizes the state of the ampoule head 33 from the outside.
- the housing of the ⁇ fmungsvoriques 1 two or more connected side walls 1 1 1, each defining an inner space for receiving an ampoule 3.
- a rotary member 12 is inserted into each of these interiors, which serves to open the respective ampoule 3.
- the opening device 1 then also has a rotatable gripping element, which is connected via a power transmission structure with all rotating elements 12.
- the Kjaftübertragungs für is formed as a plurality of sprockets, wherein a sprocket is attached to each of the rotating elements and the handle member.
- the sprockets engage each other in such a way that a rotational movement of the handle element is converted directly into a rotational movement of the rotary elements.
- the sprockets can each have a different number of teeth to produce a translation of the rotational movement between the handle member and the rotating elements. The force required to open an ampoule 3 can be further minimized by such a configuration.
- the fragmentation region 123 can be omitted. In this case, however, the ampoule head 33 is separated only from the ampoule body and not smashed. It is then possible that a liquid contained in the ampoule head 33 is retained in the ⁇ ffhungsvorraum.
- the fragmentation region 123 can also have only one of the opposing elements, which presses the ampoule head 33 against a diametrically opposite counterpart. This counterpart can be formed on the housing 1 1 or on another element. But the fragmentation region 123 can also have more than two elements, which are diametrically opposite each other. Accordingly, the second guide structure 117 would then have a plurality of opposing elements. A variety of other modifications is possible.
