- the gas channel section 47 empties into the annular space 19 between the hollow needle 10 and the needle sleeve 11 via a passage opening 48 (see FIG. 8 a / b).
- the annular space 19 thus forms a portion of the ventilation gas channel 42.
- the needle sleeve 11 has a plurality of needle sleeve passage openings 49. In total, eight such needle sleeve passage openings 49 are the same distributed around the central longitudinal axis 14 arranged around.
- the needle sleeve passage openings 49 provide a flow passage of the ventilation gas channel 42 between the annular space 19 and a further annular space 50 in a bottom side, ie the storage container 2 facing, portion of the needle sleeve 11 in this further annular space 50 is an annular disc-shaped filter carrier 51st arranged, which surrounds the hollow needle 10 annular.

- the solvent flows through the liquid channel 39 in the hollow needle 10 and exits via the two liquid channel openings 40, 41 from the hollow needle 10 into the storage container 2.
- the arrangement of the liquid channel openings 40, 41 relative to the gas channel opening 43 reduces an overflow of liquid droplets into the gas channel during injection since the liquid does not flow downwards in the direction of gravity and thus does not flow in the direction of the gas channel during injection.
- air escapes from the storage container 2 via the gas channel opening 43 through the ventilation gas channel 42 via the gas channel section 47, the passage opening 48, the annular space 19, the needle sleeve passage openings 49, the annular space 50 , the air filter 52 and from there between the needle sleeve 11 and the main body 5 of the Uber Installations- device 1 to the outside.

- the dissolved medicament flows via the liquid channel 39 through the hollow needle 10 to the storage container 2 into the use container 3.
- This flow of the dissolved medicament into the use container 3 is produced by mounting the use container 3 designed as a syringe.
- the transfer of the dissolved drug from the storage container 2 in the use of container 3 is usually in over-head position, in which the storage container 2 is disposed above the utility container 3.
- the liquid channel openings 40, 41 are closer to a residual solution of the dissolved drug, so that a residual emptying of the solution is improved.
- the gas channel opening 43 is further from the remainder of the solution than the liquid channel openings 40, 41, so that the gas channel can fulfill its ventilation function well.

- the axial channel body 55 Prior to the direction reversal channel section, the axial channel body 55 causes a corresponding extension of an axial travel of the vent gas channel 42. The axial channel body 55 effectively suppresses unwanted entrainment of liquid along the entire ventilation gas channel 42.
- the path of the gas through the gas channel 42 during venting of the storage container 2 is indicated in Fig. 13a by a directional arrow 55a.
- the axial channel body 55 is designed as up to a height of two-thirds of the entire axial height of the annular space 19 sealed sub-segment between the hollow needle 10 and the needle sleeve 11.
- the passage openings 48 are closed so that an ascent of the air flowing out of the storage container 2 is forced upon injection of the liquid into the storage container 2.

- the latter has two guide pins 65, the wall of the pressure actuating element 58 integrally on an inner side of a jacket are formed.
- the guide pin 65 slide in the displacement of the rest position into the connecting position in each case an associated guide groove 66 which is executed in an outer wall of the base 61 of the transfer device 56.
- the guide device 64 is designed such that the displacement of the hollow needle assembly 62 from the rest position to the connecting position is irreversible.
- the two guide grooves 66 each have a sawtooth-shaped profiled groove bottom 67, which is shown in FIG. 19 in cross-section and in FIG. 20a / b for one of the two guide grooves 66 in a perspective view.
- the profiling of saw teeth in groove base 67 is such that the guide pins 65 are displaced from the rest position into the connector when the pressure actuating element 58 is displaced. training position on inclined surfaces of the saw teeth can slide. In the connecting position, a sliding back of the guide pin 65 in the guide grooves 66 upwards is not possible, since the guide pins 65 are then blocked by vertical surfaces of the sawtooth profiling.
- the guide grooves 66 each continue into a guide helix 68.
- a turning of the pressure actuating element 58 from the base body 61 of the transfer device 56 is possible via this guide helix 68, as indicated by directional arrows 69, 70 in FIG. 20 a / b.
- the guide pins 65 of the pressure actuating element 58 slide in each case in one of the two guide spirals 68 on the outside of the main body 61 of the Uber Operations- device 56 until the guide pin 65 at the end of the guide spirals 68 out of engagement with the main body 61.
- the transfer device 56 After removal of the pressure actuator 58, the transfer device 56 is in the instantaneous position shown in FIG. In this instantaneous position, the connecting section 16 of the hollow needle 63 is accessible from above, as has already been explained in connection with the transfer device 1 and FIG. 6.
- the overpass device 56 is used as follows:
- the transfer device 56 is present together with the storage container 2, in which the powdered medicament is held, first in the transport position shown in FIG. 16 with inserted securing element 59 before.
- the fuse element 59 is first withdrawn. Then, pressure is applied to an upper end surface of the pressure operation member 58 from above and the pressure operation member 58 is transferred along the direction arrow 71 in FIG. 17 from the rest position to the connection position. In this displacement, the guide pin 65 rattles over the saw teeth in the groove bases 67 of the guide grooves 66 to the storage container 2 facing the end of the guide grooves 66. Now, the pressure actuator 58th rotated by rotation corresponding to the directional arrow 69 from the base body 61 of the Uber operations- device 56 so that the pressure actuator can be removed from the body 61. Now, the use of container 3, so the standard syringe, via the Luer connector to the connecting portion 16 are connected. The remaining handling is as described in connection with the embodiment according to FIGS. 1 to 12.
