In a development of such a bottle holder with which the infusion or injection device can be equipped as easily and as quickly as possible with a filled storage bottle, the invention proposes that the bottle receiver ( 2 ) is movable with respect to the spike ( 4 ) or with respect to the holding means ( 3 ) for the spike ( 4 ), and, when the bottle receiver ( 2 ) moves in the direction of the spike ( 4 ), a storage bottle arranged in the bottle receiver ( 2 ) is placed onto the spike ( 4 ) in such a way that the spike ( 4 ) punches an outlet opening into the storage bottle.

Description:
FIELD OF THE INVENTION 
     The invention pertains to a bottle holder for an injection device. 
     BACKGROUND OF THE INVENTION 
     In the field of medical engineering, injection devices are used for injecting fluids into the body of a patient. Such injection devices may be used, for example, for administering contrast agents during imaging processes such as computer tomography procedures, ultrasonic examinations and magnetic resonance tomography (MRT) procedures. In this case, the fluids to be injected such as, e.g., different contrast agents and NaCl rinsing solutions are filled into storage bottles. The bottles containing the fluids to be injected are suspended, e.g., on the upper end of a floor stand that is usually supported on casters and connected to the injection device by means of a supply hose. The injection device comprises a pump such as, for example, a peristaltic pump, by means of which the fluids conveyed in the supply hoses are pumped into a patient hose that is intravenously connected to the patient. This arrangement proved disadvantageous because the supply hose between the storage bottle and the pump of the injection device needs to be ventilated when a new storage bottle is connected. Fluid may escape during this process and lead to soiling. In addition, the floor stand, on which the storage bottles are suspended, frequently does not have the required stability and may be inadvertently knocked over. 
     In order to eliminate these disadvantages, Utility Model DE 203 06 395 U1 proposes a contrast agent supply device that features at least one bottle receiver for receiving a contrast agent bottle, as well as a dosimeter pump for dosing the contrast agent, wherein the contrast agent can be conveyed from a contrast agent bottle placed into the bottle receiver to a patient hose that can be connected to a Braun&#39;s cannula with the aid of the dosimeter pump. A hollow spike for puncturing a pierceable seal of the contrast agent bottle is provided on the bottom of the bottle receiver or each bottle receiver. When a contrast agent bottle is inserted into the bottle receiver, the contrast agent bottle is opened by the puncturing spike such that the contrast agent can initially flow from the contrast agent bottle into the hollow puncturing spike and into a tank through a line that can be connected to the puncturing spike. The tank is connected to the dosimeter pump by means of connecting lines such that the dosimeter pump can take in the contrast agent from the tank and convey the contrast agent to the patient hose intravenously connected to the patient. In this contrast medium supply device, the bottle receiver or each bottle receiver is realized in the form of a cup-shaped bottle holder, the bottom region of which features a recess for receiving the top and the bottle neck of the contrast agent bottle. The hollow puncturing spike is arranged in the center of this recess. In order to load the contrast agent supply device with a full storage bottle, the operator needs to insert the storage bottle into the bottle receiver upside down (i.e., with the bottleneck pointing downward) and press the storage bottle on the puncturing spike until the puncturing spike has pierced an outlet opening into the contrast agent bottle. 
     This procedure is complicated, time-consuming and requires correspondingly skilled operating personnel. It also entails the risk, in particular, of the operator placing the contrast agent bottle on the puncturing spike in a noncentered fashion such that the puncturing spike cannot pierce an outlet opening through the sealing cap of the contrast agent bottle. This problem occurs, in particular, with smaller contrast agent bottles, the diameter of which is smaller than the inside diameter of the bottle receiver, because the inner wall of the cup-shaped bottle receiver cannot guide the contrast agent bottle during its placement on the puncturing spike in this case. The known arrangement furthermore proved disadvantageous because it is not possible to use larger contrast agent bottles, the diameter of which is greater than the inside diameter of the bottle receiver. 
     Another disadvantage of the known device manifests itself when a depleted contrast agent bottle is withdrawn from the bottle receiver. The bottle is pulled out of the bottle receiver vertically upward such that residual fluid can drip out of the outlet opening of the contrast agent bottle. Dripping residual fluid once again leads to soiling of the contrast agent supply device. 
     SUMMARY OF THE INVENTION 
     Based on these circumstances, the invention aims to disclose a bottle holder for an injection device that makes it possible to equip the injection device with a full storage bottle as easily and quickly as possible, wherein the bottle holder should be realized in such a way that it can receive various sizes of different storage bottles. The invention furthermore aims to disclose a bottle holder for an injection device, in which a depleted storage bottle can be remove from the bottle holder as easily as possible and without dripping. 
     The inventive bottle holder features a bottle receiver for receiving a storage bottle, as well as a puncturing spike that is fixed on the bottle holder and serves for piercing an outlet opening into the storage bottle or, alternatively, holding means for attaching an exchangeable puncturing spike. The bottle receiver can be respectively displaced relative to the puncturing spike that is rigidly arranged on the bottle holder or relative to the holding means for the exchangeable puncturing spike. In order to load a full storage bottle into an injection device that is equipped with such a bottle holder, the storage bottle is inserted into the bottle receiver upside down and pressed vertically downward. This causes the movable bottle receiver to move in the direction of the puncturing spike and places the storage bottle on the puncturing spike in such a way that it pierces an outlet opening into the storage bottle. Due to the guided movement of the bottle receiver relative to the puncturing spike, it is always ensured that the storage bottle and, in particular, its bottle neck is placed on the puncturing spike in a centered fashion such that the puncturing spike can pierce an outlet opening, e.g., through a cap or a thin membrane that seals the neck of the storage bottle. 
     The movement of the bottle receiver relative to the puncturing spike is preferably guided by means of a guide arrangement that is coupled to a spring. In this case, the bottle receiver can be displaced between an upper end position and a lower end position against the restoring force of a spring that is realized, in particular, in the form of a pressure spring. The bottle receiver can be advantageously fixed in the upper and/or in the lower end position by means of a locking mechanism. In its upper end position, the bottle receiver is ready to receive a new, full storage bottle. After inserting a full storage bottle into the bottle receiver, the bottle is pressed vertically downward such that the bottle receiver is moved toward the puncturing spike arranged thereunder, namely until the lower end position of the bottle receiver is reached. The puncturing spike has pierced an outlet opening into the storage bottle once the bottle receiver reaches the lower end position. The preferably hollow puncturing spike is connected to a supply line, through which the fluid can then be conveyed from the storage bottle into a pump of the injection device. 
     In order to allow the secure placement of storage bottles of various shapes and sizes into the bottle receiver of the inventive bottle holder, a funnel-shaped receiving element for inserting and holding the neck of a storage bottle therein is preferably provided on the inventive bottle holder. Furthermore, holding means that features flexible or pliable holding elements are preferably arranged on the bottle holder. The flexible holding elements at least partially encompass the storage bottle on its outer circumference and thusly fix the storage bottle in the bottle receiver. Due to the flexible or pliable design of the holding elements, they adapt to the size and the shape of the storage bottle and nonpositively adjoin the outer circumference of the storage bottle in order to fix this storage bottle in the bottle receiver. Consequently, it is also possible to fix bottles of different sizes and, in particular, different diameters in the bottle receiver. 
     The inventive bottle holder is preferably coupled to a housing part of the injection device such that it can be pivoted between a normal vertical position and a pivoted horizontal position. In this case, the pivoting mechanism is preferably realized such that the bottle holder can be pivoted relative to the housing part of the injection device in such a way in its lower end position that the storage bottle situated in the bottle receiver is transferred into an essentially horizontal position. In this horizontal position, the storage bottle can be pulled out of the bottle receiver without residual fluid dripping out of the outlet opening of the storage bottle. 
     In order to prevent the bottle holder from being inadvertently pivoted into its horizontal position, it is advantageous to provide a locking mechanism that locks the bottle holder in its vertical position. The bottle holder comprises an unlocking lever for disengaging the locking mechanism such that the bottle holder can subsequently be pivoted from its vertically lower end position into the horizontal position. 
     In order to ensure that the bottle receiver is in its upper end position, in which it can be once again loaded with a new storage bottle, when the bottle holder is pivoted back from its pivoted horizontal position into the normal vertical position, it is preferred to provide an automatic unlocking mechanism that automatically moves the bottle receiver into its upper end position when the bottle holder is pivoted back.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  shows the injection head  21  of an injection device for injecting two different or identical contrast agents and a NaCl rinsing solution into the body of a patient, wherein the injection device features inventive bottle holders for receiving a total of three storage bottles for the two contrast agents and the NaCl rinsing solution. Such injection devices are used, for example, for injecting contrast agents during imaging processes such as computer tomography procedures, ultrasonic examinations and magnetic resonance tomography (MRT) procedures. The injection head  21  illustrated in  FIG. 2  comprises an outer housing  22 , in which a pump is arranged, preferably a peristaltic pump for conveying the contrast agents and the rinsing solution in a patient hose connected to the patient. A hose, in which the fluids to be injected are conveyed, is inserted into the peristaltic pump. The fluids to be injected are filled into (not-shown) storage bottles. In order to receive the storage bottles, the injection head  21  illustrated in  FIG. 1  features a total of three bottle holders  1 ,  1   a ,  1   b . The three bottle holders  1 ,  1   a ,  1   b  are arranged above a panel  23  of the injection head  21 . The panel  23  can be closed with a cover  24 . In the side view illustrated in  FIG. 2 , the cover  24  is shown in the closed position. In  FIG. 1 , the upper region of the panel  23  is visible through the preferably transparent cover  24 . Channel-shaped recesses (that are covered by the cover  24  and therefore not visible) are provided in the upper region of the panel  23 , wherein a branched hose arrangement (that is not graphically illustrated) can be inserted into said recesses. The hose arrangement may consist, in particular, of a hose arrangement of the type described in detail in EP 2 011 541 A2. This hose arrangement comprises a total of three supply hoses, namely a first supply hose for a first contrast agent, a second supply hose for a second contrast agent and a third supply hose for a rinsing solution (particularly NaCl). The three supply hoses are connected to the storage bottles for the contrast agents and the rinsing solution and clipped into the branch channels arranged in the upper region of the panel  23 . The supply hoses arriving from the storage bottles converge in a junction element that is inserted into a circular recess. The junction element comprises an output hose that is inserted into the pump arranged in the housing  22  underneath the cover  24 . 
     The three bottle holders  1 ,  1   a ,  1   b  illustrated in  FIG. 1  are provided for receiving the storage bottles. The bottle holders are respectively designed identically. Details of the design of the bottle holders can be gathered from the detailed illustration in  FIG. 1 a   , as well as the sectional representations in  FIG. 3  and the perspective rear view in  FIG. 4 . The three bottle holders  1 ,  1   a ,  1   b  are respectively coupled to a housing part  20  of the injection head  21  in a pivoted fashion. Consequently, each of the three bottle holders  1 ,  1   a  and  1   b  can be pivoted between a normal vertical position and a horizontal position. In the illustration according to  FIG. 1 , the bottle holder  1  arranged on the left side and the bottle holder  1   b  arranged on the right side respectively are in their normal vertical position and the bottle holder  1   a  in the middle is in its horizontal position. A storage bottle can be inserted into the bottle holder and connected to a supply hose in the vertical position. After the storage bottle placed into the bottle holder has been connected to a supply hose, the bottle holder remains in its vertical position in order to withdraw the fluid from the storage bottle once the pump is running. The bottle holder can be pivoted into its horizontal position once the storage bottle has been depleted due to the operation of the pump. The depleted storage bottle can then be horizontally pulled out of the bottle holder in this horizontal position. Since the depleted storage bottle is pulled out of the bottle holder in the horizontal position, it is ensured that the depleted storage bottle is disconnected from the supply hose attached thereto without dripping. After the depleted storage bottle has been pulled out of the bottle holder, this bottle holder can be once again pivoted back into its normal vertical position. In the normal position, a full storage bottle can then be once again inserted into the bottle holder from above in the vertical direction. 
     In order to receive a storage bottle, each of the bottle holders  1  features a bottle receiver  2  ( FIG. 1 a   ). The bottle receiver  2  comprises a funnel-shaped receiving element  6 , into which the bottle neck of a storage bottle can be inserted upside down ( FIG. 2 ). The shape of the funnel-shaped receiving element  6  is advantageously adapted to the typical bottle shape of injection medium storage bottles or rinsing solution storage bottles, respectively. In order to ensure that the storage bottle is reliably held in the bottle holder, the bottle receiver  2  furthermore features holding means  7  that is arranged above the receiving element  6 . The holding means  7  fixed on the receiving element features flexible holding elements  8 . The flexible holding elements  8  encompass a storage bottle inserted into the bottle holder on its outer circumference in the central region or in the bottom region of the storage bottle such that the storage bottle is reliably fixed in the bottle holder and, in particular, in the receiving element  6 . Due to these measures, storage bottles of different shapes and sizes can be securely fixed in the bottle receiver. 
     The flexible holding elements  8  are preferably designed in such a way that they positively and nonpositively adjoin the outer circumference of the storage bottle. For this purpose, the holding means  7  features at least two holding elements  8   a  and  8   b  that are arranged on diametrically opposite locations referred to the insertable storage bottle ( FIG. 1 a    and  FIG. 4 ). Each of the identically designed holding elements  8   a  and  8   b  comprises a pair of first holding tabs  9   a ,  9   b  that are connected to one another by means of a connecting part  9   d  with the shape of a segment of a circle. A downwardly directed second holding tab  9   c  is arranged on the connecting part  9   d . The second holding tab  9   c  extends between the two holding tabs  9   a ,  9   b  of the pair of first holding tabs and protrudes over the inner circumference of the connecting part  9   d  in the radial direction. Each holding element  8   a ,  8   b  is advantageously realized in one piece in the form of an injection-molded plastic part, i.e., the pair of first holding tabs  9   a ,  9   b , the connecting part  9   d  and the second holding tab  9   c  are jointly molded in one piece in the form of an injection-molded part. Each holding element  8   a ,  8   b  is advantageously fixed on the funnel-shaped receiving element  6  in a detachable fashion by means of a latching or clamping mechanism. A splash guard  5  that is advantageously realized in one piece with the receiving element  6  in the form of an injection-molded plastic part is provided on the underside of the funnel-shaped receiving element  6 . 
     Holding means  3  for attaching an exchangeable puncturing spike  4  is provided underneath the bottle receiver  2  ( FIGS. 2 and 3 ). An inserted puncturing spike  4  is illustrated in the sectional representations according to  FIG. 3 . The holding means  3  features a guide rail or a guide groove  4 . A holding part of a puncturing spike  4  that is realized with a complementary shape can be pushed into this guide rail or guide groove  4 . The puncturing spike  4  advantageously consists of a hollow-cylindrical spike with a puncturing point, to which one end of a supply hose is connected, wherein the other end of said supply hose is connected to the junction element. As an alternative to this arrangement, the puncturing spike may also be permanently integrated into the bottle holder in that the puncturing spike is fixed on the holding means  3  or realized in one piece therewith. However, the described arrangement of a puncturing spike  4  that is detachably fixed on the holding means  3  is more practical because this design ensures that a used puncturing spike can be easily and quickly cleaned or exchanged, respectively. 
     In order to produce a connection between the supply hose and an initially closed storage bottle inserted into the bottle holder  1 , a mechanism is provided that makes it possible to automatically pierce an outlet opening into the storage bottle by means of the puncturing spike. For this purpose, the bottle receiver  2  is realized such that it can be respectively moved relative to the puncturing spike  4  or relative to the holding means  3  for the puncturing spike. During a vertical movement of the bottle receiver  2  toward the puncturing spike, the storage bottle situated in the bottle receiver  2  is placed on the puncturing spike in such a way that the puncturing spike pierces an outlet opening into the storage bottle. Such storage bottles for contrast agents or rinsing solutions are usually sealed with a cap or a thin membrane that can be easily pierced by the puncturing spike. When the storage bottle is placed on the puncturing spike, the motion mechanism of the inventive bottle holder therefore automatically pierces an outlet opening into the cap or into the membrane of the storage bottle when the bottle receiver is manually pushed downward on the puncturing spike in the normal vertical position of the bottle holder. This merely requires that the operator presses the storage bottle inserted into the bottle holder  1  downward by exerting pressure upon the bottom thereof such that the bottle receiver  2  is also pushed downward in the direction of the puncturing spike. 
     The mechanism for respectively moving the bottle receiver  2  relative to the puncturing spike or the holding means  3  is illustrated in the sectional representations according to  FIG. 3 .  FIG. 3 a    shows that each bottle holder  1  comprises a housing part  10 , on which the holding means  3  for attaching an exchangeable puncturing spike  4  is fixed. A pivoted lever  11  is fixed on the housing part  10 . The pivoted lever  11  is supported in a pivoting fashion on the housing part  20  of the injection head  21  by means of a pivot bearing  12 . The mechanism for pivoting the bottle holder  1  relative to the housing part  20  from its (normal) vertical position illustrated in  FIG. 3 a    into a horizontal position is described below. 
     A connecting part  15  featuring a vertical bore  36  is arranged on the underside of the funnel-shaped receiving element  6  and realized in one piece therewith. A guide rod  16  that is fixed on the connecting part  15  by means of a mounting bolt  35  protrudes into the aforementioned bore  36  ( FIG. 3 c   ). The guide rod  16  has a smaller diameter than the bore  36  and extends vertically downward up to the lower end  37  of the connecting part  15 . A sleeve  38  is inserted into the housing part  10  and fixed therein. The sleeve  38  has a slightly smaller diameter than the bore  36  in the mounting part  15  and extends vertically upward from the housing part  10  up to the lower end  37  of the connecting part  15 . The pressure spring  12  realized in the form of a coil spring is arranged in the sleeve  38 , wherein the lower end of said coil spring rests on the bottom  39  of the sleeve  38 . In its relaxed state (that is illustrated in  FIG. 3 c   ), the upper half of the pressure spring  12  encompasses the guide rod  16  and the upper end of the pressure spring  12  braces itself against a flange  40  on the guide rod  16 . Consequently, the bottle receiver  2  can be displaced in the longitudinal direction of the guide rod  16  against the restoring force of the pressure spring  12 . When pressure is exerted vertically downward upon the bottle receiver  2  and against the restoring force of the pressure spring  12 , the pressure spring  12  is compressed and the lower region of the connecting part  15  is pushed over the sleeve  38 , wherein the sleeve  38  engages into the bore  36  and the guide rod  16  (with the encompassing pressure spring  12 ) simultaneously engages into the sleeve  38 . A guide arrangement that guides the movement of the bottle receiver  2  in the respective longitudinal direction of the sleeve  38  or the guide rod  16  is formed due to the cooperation of the guide rod  16 , the mounting part  15  and the sleeve  38 . However, it would also be conceivable to realize other embodiments of this guide arrangement, wherein the coil spring could, for example, be replaced with other spring elements such as, e.g., spiral springs or leaf springs. 
     A bolt  13  with a groove  14  arranged in the vicinity of its lower end is furthermore fixed on the mounting part  15  ( FIG. 3 a   ). The bolt  13  extends downward parallel to the guide element  16  and engages into a bore  17  in the housing part  10 . In the normal vertical position of the bottle holder  1 , the bottle receiver  2  can be displaced between an upper (vertical) end position and a lower (vertical) end position along the guide element  16  and against the restoring force of the pressure spring  12 . In  FIG. 2 , the bottle receiver  2  is illustrated in its upper end position while the illustration according to  FIG. 3  shows the bottle receiver  2  in its lower end position. 
     According to the sectional representation in  FIG. 3 b   , a second guide element in the form of a second guide rod  16   a  is provided in addition to the first guide element formed by the guide rod  16 . This second guide rod  16   a  is realized similar to the bolt  13  and fixed on the mounting part  15  ( FIG. 3 b   ). The second guide rod  16   a  also extends downward parallel to the first guide rod  16  and engages into a bore  17 ′ in the housing part  10 . A flange  34  is screwed on the lower end of the second guide rod  16   a . In the upper end position of the bottle receiver illustrated in  FIG. 3 b   , the upper side of the flange  34  adjoins a step in the bore  17 ′ and thusly fixes the bottle receiver  2  in its upper end position in connection with the restoring force of the pressure spring  12  that presses the bottle receiver  2  upward when the bottle holder is in its normal vertical position. The bottle receiver  2  can be pressed from its upper end position into the lower end position by exerting vertical pressure upon the bottle receiver from above against the restoring force of the pressure spring  12 . 
     A latching mechanism is provided in the lower end position in order to fix the bottle receiver  2  in its lower end position. The latching mechanism for fixing the bottle receiver  2  in its lower end position comprises the bolt  13  that extends through the bore  17 , as well as a latching tab  18  that engages into the groove  14  on the lower end of the bolt  13  when the bottle receiver  2  is in its lower end position. The lower end  19  of the bolt  13  is realized in a tapered fashion in order to actuate the latching mechanism. When the bottle receiver  2  is pressed downward from its upper end position, the bolt  13  fixed on the bottle receiver  2  moves through the bore  17  of the housing part  10  and engages into a sleeve  26  fixed on the housing part  10 . A springable latching tab  18  is arranged on the underside of the sleeve  26 . When the pointed end  19  is pushed through the sleeve  20 , the pointed end  19  of the bolt  13  initially presses the springable latching tab  18  sideward until the latching tab engages into the groove  14  during the continued insertion of the bolt  13  and thusly locks the bolt  13 , as well as the bottle receiver  2  fixed thereon by means of the receiving element  6 , in this position (lower end position). During the movement of the bottle receiver  2  from its upper end position into the lower end position, the storage bottle in the bottle receiver  2  also moves toward the holding means  3  and the puncturing spike arranged therein such that the puncturing spike pierces an outlet opening into the storage bottle—as already described above. When the bottle receiver  2  is in its lower end position, the pump of the injection device can be started—after the storage bottle has been opened—in order to convey the liquid situated in the storage bottle. 
     Once the storage bottle has been depleted, the bottle holder  1  can be pivoted from its normal vertical position into the horizontal position by means of the pivoting mechanism in order to remove the depleted storage bottle. This can be achieved by unlocking an unlocking lever  11  ( FIG. 1 ) that holds the pivoting mechanism in its locked position. For this purpose, the unlocking lever  11  is coupled to the pivot bearing  12 , by means of which the pivoted lever  11  of the bottle holder  1  is coupled to the housing part  20  of the injection head  21 . 
       FIG. 5  shows different positions of the bottle holder  1  relative to the housing part  20  of the injection head  21  while the bottle holder  1  is pivoted from its normal vertical position ( FIG. 5 a   ) into an intermediate position ( FIG. 5 b   ) and ultimately into its pivoted horizontal position ( FIG. 5 c   ) and then once again pivoted back into its normal vertical position. In this respect, the illustration in  FIG. 5 a    corresponds to the illustration in  FIG. 3 , in which the bottle holder  1  is in its normal vertical position and the bottle receiver  2  is in the lower end position. In this position, the bottle holder  1  can be pivoted into the horizontal position illustrated in  FIG. 5 c    after the pivoting mechanism has been unlocked by actuating the unlocking lever  11 . The bottle receiver  2  remains in its lower end position while the bottle holder  1  is pivoted from the vertical position into the pivoted horizontal position. This is illustrated in the sequence of pivoting positions shown in  FIGS. 5 a , 5 b    and  5   c.    
     In order to ensure that the bottle receiver  2  is moved into its upper end position when the bottle holder  1  is pivoted back into the normal vertical position from its pivoted horizontal position, a mechanism is provided that automatically moves the bottle receiver  2  back into the upper end position from its lower end position while the bottle holder  1  is pivoted back into the normal vertical position from the pivoted horizontal position. This mechanism is illustrated in detail in the enlarged representation according to  FIG. 6  and comprises a locking hook  27  that is fixed on a bolt  28 . The bolt  28  is rotatably supported in a bearing part  33  that is fixed on the housing part  20  ( FIG. 4 ). The locking hook  27  features a latching tab  29  that cooperates with a latching tab  30  that is arranged on the sleeve  26  and connected to the latching tab  18 . In the lower end position of the bottle receiver  2  illustrated in  FIG. 3 , the latching tabs  29  and  30  lie on top of one another without engaging. When the bottle holder  1  is pivoted into its pivoted horizontal position, the latching tab  30  engages with the latching tab  29  and pulls the hook  27  upward ( FIG. 5 b   ). Due to these measures, the hook  27  is slightly raised and turned by turning the bolt  28  relative to the bearing part  33 . Due to the rotational movement of the hook  27 , the latching tabs  29  and  30  are once again disengaged and the bottle holder  1  can be additionally pivoted about the pivot bearing  12  until it reaches its pivoted horizontal position illustrated in  FIG. 5 c   . In this pivoted horizontal position, the outer surface of the pivot bearing  11  rests on an abutment  31  of the housing part  20  and can no longer be pivoted further downward. In the pivoted horizontal position illustrated in  FIG. 5 c   , the depleted storage bottle can be pulled out of the bottle receiver  2  without dripping. 
     When the bottle holder  1  is pivoted back into its normal vertical position ( FIG. 5 d   ) from its pivoted horizontal position ( FIG. 5 c   ), the latching tab  30  initially comes in contact with a guide surface  32  of the latching tab  29  in an intermediate position that is illustrated in  FIGS. 5 d    and  6 . As the bottle holder  1  is further pivoted back into its normal position, the latching tab  29  presses the latching tab  30  in the direction of the pivoting movement with its guide surface  32 . The latching tab  30  is connected to the flexible latching tab  18  such that the latching tab  18  is pressed out of the groove  14  of the bolt  13  in the moving direction of the backward pivoting process. Due to these measures, the bolt  13  locked in the lower end position of the bottle receiver  2  is released and the bottle receiver  2  automatically moves back into its upper end position due to the restoring force of the pressure spring  12 . Once the bottle holder has been completely pivoted back into its normal vertical position, the bottle receiver  2  has completely moved into its upper end position. This ensures that the bottle receiver  2  is in its upper end position once the bottle holder  1  has been pivoted back into its normal vertical position. In this normal vertical position, the bottle receiver can then be loaded with a new, full storage bottle. This is achieved by inserting a new storage bottle into the bottle receiver  2  and pressing the new storage bottle vertically downward in order to pierce an outlet opening into the storage bottle in the above-described fashion due to the movement of the bottle receiver  2  in the direction of the puncturing spike. 
     The invention is not limited to the described exemplary embodiment. For example, the inventive bottle holder is not only suitable for use in an injection device for injecting contrast agents, but also, for example, in infusion devices. In contrast to the described exemplary embodiment, it would also be possible to arrange less than three bottle holders on an injection or infusion device. Depending on the respective application, however, it would also be conceivable to provide more than three bottle holders of the inventive type on a corresponding device. It is also possible to utilize an inventive bottle holder for receiving a storage bottle together with a conventional bag holder for receiving a bag that contains a fluid to be injected.
