    Device for distributing substances
    [2] To this end, the feeding device has conventionally been a syringe with a hypodermic needle, which needle punctures a container, for example a punctureable closure or plug of an injection container, and then pushes the syringe to Is injected into the container. In this process, a preparatory step of filling the syringe is required, in which the desired amount of medium from the storage container is supplied to the syringe or the syringe is filled from a conventional vial containing the measured amount of the relevant medium. These feeding operation steps take time on the one hand, because the hypodermic needle and the syringe must be unpacked, the hypodermic needle mounted on the syringe, the vial opened or perforated, and the syringe removed. On the other hand, these measures present a significant risk of contamination of the medium.
    [1] The present invention relates to a material dispensing apparatus. The main but not exclusive use of the device is to supply a desired volume of medium, in particular a liquid medium, into a receptacle. Preferably the medium to be supplied is an additive which is introduced, for example, as an admixture of the active ingredients into a fluid located in a container. The container may be an infusion container in which the contents in the container are mixed with the medium as additional active ingredients.
    [15] The invention is explained below with reference to the embodiments illustrated in the drawings.

    [17] 2 is a longitudinal sectional view of the device of FIG. 1;
    [18] 3 is a longitudinal sectional view corresponding to FIG. 2 but with a protective cover removed;
    [19] 4 is a longitudinal sectional view of the device in an operational state pushed with a punctable stopper stopper of the injection container;
    [20] FIG. 5 is similar to FIG. 4 but with the contents of the supply container of the apparatus being compressed and ejected. FIG.
    [21] Fig. 6 is a longitudinal sectional view of the device in the compressed and discharged state and withdrawn from the stopper stopper;
    [22] 7 is a longitudinal sectional view of the device in a state in which it is compressed and discharged and corresponds to a protective position of the safety device.
    [3] It is an object of the present invention to devise an apparatus which allows the supply of media in a relatively simpler and more reliable manner as opposed to the conventional apparatus.
    [4] This object is achieved by the media supply device as claimed in the present invention, which is a closing unit having a supply container for holding the relevant medium, a hypodermic needle for the medium to be supplied, and a closing unit. An outer end protruding from and an active device covering the outer end of the hypodermic needle from the active protective state to an inactive use state for supply of media from the hypodermic needle.
    [5] The supply container holding the medium together with the integral hypodermic needle and the protruding end, ie the safety device covering the tip of the needle, as specified in the device claimed in the present invention, is combined into a combined unit so that the desired amount of the associated medium Can be prepared before the feeding process of the supply container of the apparatus. Since the tip of the needle is covered with a safety device, the device can be easily handled with the hypodermic needle protected and ready for the feeding process. Intermediate steps of feeding the medium and preparing the syringe for the feeding process are unnecessary. Thus, the desired simplicity, time savings, and increased protection against contamination are achieved.
    [6] If the outer end of the hypodermic needle is designed to puncture the punctureable stopper of the container holding the medium to be fed, the safety device can be removed from the supply container and have a protective cover surrounding the protruding end of the hypodermic needle, Has a safety body that can be pushed back into the use position by contact from the advanced protective position on the end of the hypodermic needle when it is perforated and pushed forward again to the protective position when the hypodermic needle is pulled out of the stopper. . In this embodiment, the operation becomes very simple.
    [7] Preferably, the protective cover is connected to the supply container via a predetermined breakdown point and has a finger grip as a purge to twist off the protective cover of the supply container.
    [8] As a safety body, the safety device may have an annular body movably guided in a section of the hypodermic needle protruding from the closure unit, the annular body being connected to the closure unit by elastic retaining means creating a holding force and The holding force of the holding means can be force-fit to an advanced protective position covering the end of the hypodermic needle, and overcome the holding force and be pushed back to the use position along the hypodermic needle. The indicated annular body on the free face forms an annular widened contact surface projecting radially on the front point of the safety device on the other part, the annular body upon opening by removal of the perforated point of the container by the widened contact surface. Reliable contact behavior of is obtained. Furthermore, the contact surface prevents the hypodermic needle from clogging or damaging the sensitive tip when the punctureable stopper of the supply container is punctured.
    [9] The retaining means is formed by a support member, the support member is divided by a joint, articulated respectively to the annular body and the closing unit, and extends substantially parallel to the hypodermic needle in the protected position, It extends from the hypodermic needle to the unfolded position when the annular body is pushed back to the use position along the hypodermic needle.
    [10] Preferably, the support member is a rod-shaped plastic member, the support member being molded into a closed unit and one piece and divided by a bent connection at almost half of its length. In this embodiment, the intrinsic elasticity of the material of the support member is such that the annular body is sheared forward of the hypodermic needle so that the annular body automatically returns back to the protected position after being pushed back to the use position or simply forwards slightly further forward after using the device. Allows you to automatically advance at least partially back into wealth. Since the bend connection is fully folded laterally, the rod-shaped plastic parts forming each bend connection can be arranged in contact with each other on top of each other so that a high penetration depth of the hypodermic needle into the supply container can be achieved. A punctureable stopper having a corresponding thickness of the supply container can be punctured in a controlled manner by a hypodermic needle.
    [11] In one particularly advantageous embodiment, the closing unit supports the snap ring, which snap ring can be removed from the closing unit and surrounds the support member and is supported towards its bent connection to fix in a position corresponding to the protective position. It can be pushed along the member. Here, there may be a catch notch on the bending connection, the catch ring catches the snap ring and the safety device is releasably fixed in the protected position, in which the annular body is the outer end of the hypodermic needle. Wrap it safely.
    [12] Supply container uses the known bottle pack ® process (Bottlepack® process) may be made of a plastic container; The closing unit, which is an insertion member, is inserted at its open end before being closed by the protective cover.
    [13] In the central area the body of the insertion member contains a hypodermic needle that is positioned continuously therein; Its inner end faces the inside of the supply container and slightly protrudes from the body of the closing unit. The insertion member, which forms a closing unit between the opposing inner end of the hypodermic needle and the medium located in the supply container, has a membrane as a blocking member, which increases the pressure of the medium located in the supply container. When pressed against the end of the hypodermic needle and perforated by the hypodermic needle.
    [14] Increasing the pressure of the medium and thereby perforating the membrane can be effected by compressing the supply container.
    [23] In the figures, the supply container is generally indicated with reference 1. It is a plastic container in the form of an ampule made using the known Bottlepack ® process, which has a wall 2 with a fold and is made in the form of bellows, so that the supply container 1 is It can be discharged by compression from the structure shown in FIGS. 1 to 4 (see FIGS. 5 to 7). In the neck part, the closing unit 3 is inserted into the supply container 1 as an insertion member; Several components are molded in the body of the closed unit molded of plastic. Among others, the protective cover 5 is formed in which the safety device 17 is molded into the body of the supply container 1 on a predetermined point of failure 7 (see FIGS. 1 and 3) (before using the supply device). It has a laterally protruding finger grip 9 which is protected by the side and used as a point to force to twist off the protective cover of the supply container 1 at the intended breakdown point 7. 3 shows the same operating state of the device as in FIGS. 1 and 2 but with the protective cover 5 removed.
    [24] As is apparent from FIGS. 2 and 3, in the central region the main body of the closing unit 3 is penetrated by the hypodermic needle 11; Its inner end 12 projects slightly inside the body of the closing unit 3. Between the inner end 12 of the hypodermic needle 11 and the inner side of the supply container 1 is a membrane 13 which is part of the insertion member of the closing unit 3.
    [25] The hypodermic needle extends from the outer end of the body of the closing unit 3 by a length approximately corresponding to the length of the hypodermic needle of the syringe. 2, 3 and 7 show the protruding outer end 15 of the hypodermic needle 11 covered by the safety device 17 in the protected position, ie protected operating state.
    [26] The safety device 17 is integrally molded with the main body of the closing unit 3 and has an annular body 19, which annular body 19 is placed on the hypodermic needle 11 to cover the end of the hypodermic needle, ie the tip of the needle. It is movable and is in a protective position (see FIGS. 2, 3 and 7) on the outer end 15 of the hypodermic needle 11. The annular body 19 is integrally molded to the main body of the closing unit 3 by a rod-shaped support member 21 integrally molded, and the connection points of the main body of the closing unit 3 and the annular main body 19 are It is flexible in the way of bending joints. In addition, there are bending connections that divide the support member 21 on about half the position of the support member 21. When the annular body 19 is pushed from the protected position along the hypodermic needle 11 to the position of use of the device (see FIGS. 5 and 6), the sections of the support member 21 delimiting the bending connection 23 are rotated. Swivel so that the sections are unfolded from the hypodermic needle 11 and folded as shown in FIG. 5.
    [27] 5 and 4 show the device with the hypodermic needle 11 having the front end 15 puncturing the punctureable stopper 25 of the injection container 26. Here, the annular body 19 is pushed back to the use position along the hypodermic needle 11 from the protective position aligned with the end 15 of the hypodermic needle. By compressing the bellows-shaped wall 2 of the supply container 1 (see FIG. 5), the pressure of the containing medium is increased so that the membrane 13 is directed against the opposite end 12 of the hypodermic needle 11. Pressed and perforated by it. Therefore, when the supply container 1 is compressed, the medium contained therein is compressed by the injection container 26 so that a single dose of the active ingredient corresponding to the contents of the supply container 1 is injected into the injection container 26. It is added to the content of.
    [28] FIG. 6 shows an operating state in which the supply container 1 is retracted from the stopper 25 of the injection container 26 after it is discharged by compression. Due to the inherent elasticity of the support member 21, the annular body 19, which has been pushed backwards from the protected position, contacts and overcomes the elastic or holding force of the support member 21 when the hypodermic needle is inserted into the stopper 25. By the elastic force in part again with respect to the end 15 of the hypodermic needle.
    [29] 7 shows the operating state of the device after its use is complete, and although the protective cover 5 is no longer mounted, the protruding outer end 15 of the hypodermic needle 11 is secured by the safety device 17. Is fixed again. For this purpose, the snap ring 29 removably placed on the body of the closing unit 3 is removed from the closing unit, advanced along the hypodermic needle 11, sliding on the support member 21, and FIG. 6. From the position shown in the drawing to the hypodermic needle 11, the annular body 19 advances to the end 15 of the hypodermic needle 11. On the bend connection 23, the support member 21 has a shaped locking cutout 30, in which a snap ring 29 is fitted (see FIG. 7).
    [30] After the snap ring 29 is caught by the locking cutout 30 on the bend connection 23 of the support member 21, the hypodermic needle 11 is covered by an annular body 19 covering its end portion to cover the protective cover ( Although 5) has been removed, the emptied device can now be safely discarded. Needless to say, the feeder claimed in the present invention not only adds the desired volume of liquid medium to the injection container, but also liquids or gases and / or particulates as long as it can be supplied or needs to be fed by a hypodermic needle. The same may be used for particle-laden media.
