Definitions
- the invention relates to a metering device for metering therapeutic liquids onto a carrier element.
- the invention also relates to a method for dosing therapeutic liquids onto a carrier element.
- Transdermal therapeutic systems have a carrier element such as a thin absorbent matrix.
- the therapeutic liquid is applied to the, in particular, absorbent matrix with the aid of a tampon process.
- An absorbent matrix cannot be used to produce a transparent TTS. Dosing onto a matrix, in particular an adhesive matrix, by means of a tampon method leads to a large spread in the amount of therapeutic liquid applied.
- the object is achieved with a metering device according to claim 1 and a method according to claim 10.
- the metering device for metering therapeutic liquid onto a carrier element, such as a particularly transparent matrix, has a container for providing therapeutic liquid.
- a liquid dispensing device is fluidically connected to the container.
- the dispensing device which in particular has one or more pumps, is fluidically connected to a dosing head.
- the dosing head serves to dispense the therapeutic liquid conveyed by the liquid dispensing device to or onto an upper side of the carrier element.
- a movement device is connected to the dosing head. With the help of the movement device, the dosing head can be moved while the therapeutic liquid is being dispensed. In this way, the liquid is distributed during the dispensing of the liquid. In this way, good results can be achieved for a TTS with, in particular, a uniform layer of a therapeutic liquid. This serves in particular to ensure that the therapeutic active substance can be easily delivered to the patient.
- a pivoting movement or a rotary movement of the dosing head takes place.
- a pivoting or rotating movement through 160 ° to 180 ° is preferred here.
- the dosing head has at least two dosing units.
- these at least two metering units are arranged opposite one another, in particular opposite the pivot axis.
- metering units can also be provided. It is preferred here that the swivel or rotation angle is adapted to the number of metering units. For example, if four dosing units are provided, which are preferably arranged offset by 90 °, the dosing head carrying the dosing units is rotated or pivoted by about 80 ° to 90 °. As a result, an essentially complete circle of therapeutic fluid is again generated on the carrier element.
- each metering unit has at least two metering nozzles.
- two partially circular paths of therapeutic liquid are generated on the carrier element.
- two substantially complete rings of therapeutic fluid are produced on the carrier element. In this way, too, a further improvement in the uniform delivery of therapeutic liquid can be achieved.
- the dispensing of therapeutic liquid is stopped in that in particular no liquid is dispensed by the liquid dispensing device, which preferably has rotary piston or wobble piston pumps.
- the dosing nozzles can also be provided with valves in order to prevent therapeutic liquid from running on. If the liquid continues to run, the relative movement of the dosing head and the carrier elements could result in Promotionic material is dragged between two adjacent carrier elements and thus no clean edges are created.
- the dosing head is connected to a lifting device.
- a lifting device By providing such a lifting device, it is possible to lift the dosing head after the therapeutic liquid has been dispensed. This has the result that when the liquid delivery is interrupted, the risk of running on is reduced.
- it is possible to provide metering nozzles without valves by providing a Hubeinrich device. Raising the dosing head after it has been dispensed and lowering the dosing head again for the next dispensing is sufficient to prevent liquid from being carried over from one TTS to the next.
- the lifting device which brings about both lifting and lowering of the dosing head, is operated pneumatically.
- the moving device for pivoting or rotating the dosing head can be operated electrically or pneumatically.
- the invention also relates to a device for producing therapeutic transdermal systems (TTS).
- TTS therapeutic transdermal systems
- This has a feed device, such as a conveyor belt.
- a carrier element is fed with the aid of the feed device.
- the carrier element can be for example a continuous material that will be cut later.
- the device has a metering device as described above. With the aid of the metering device, therapeutic liquid is metered onto the carrier element. In particular, the liquid is metered onto an endless carrier element at regular intervals so that appropriate products can then be manufactured by cutting or punching.
- the device has at least one feed device for at least one cover element. The covering element is preferably supplied after the therapeutic liquid has been applied by the metering device, so that the carrier element is covered. As a result, the therapeutic liquid is disposed between the support element and the cover element.
- a cutting or punching device can be provided for producing the corresponding products by cutting or punching.
- the invention also relates to a method for dosing a therapeutic liquid onto a carrier element.
- the method according to the invention is carried out with the aid of the metering device according to the invention and in particular the device for producing therapeutic transdermal systems as described above.
- a therapeutic liquid is metered onto a carrier element by means of a dispensing device.
- a dispensing head fluidly connected to the dispensing device is moved while the therapeutic liquid is being dispensed in order to achieve the most uniform possible application of the therapeutic liquid to the carrier element.
- the Trä gerelement can also be moved accordingly.
- the dosing head is preferably pivoted or rotated, it being particularly preferred that the dosing head is rotated by 160 ° to 180 ° while the liquid is being dispensed.
- the dosing head After dosing, the dosing head is moved back into a starting position and, in particular, swiveled back or rotated back. It is also preferred that the dosing head is raised after dosing or at the end of the dosing process. The dosing head is lowered again before dosing.
- Fig. 1 is a greatly simplified schematic side view of a Dosiervor direction
- FIG. 2 shows a plan view of a carrier element in the direction of arrow II in FIG. 1.
- the metering device has a loading container 10 in which the therapeutic liquid is stored.
- the container 10 is fluidly connected to a liquid dispensing device 14 via a line 12.
- the liquid dispensing device 14 has in particular special pumps, preferably rotary piston or wobble piston pumps.
- the liquid dispensing device 14 is via a line 16 with a dosing sierkopf 18 connected. Lines 20, which lead to nozzles 22, are arranged within the dosing head 18.
- two nozzles 22 each form a dosing unit 21.
- the dosing head 18 is connected to a movement device 24. With the aid of the movement device 24, the dosing head 18 can be rotated or pivoted about a central axis 26.
- a lifting device 28 is also connected to the dosing head 18. With the help of the lifting device 28, the dosing head can be raised or lowered in the direction of an arrow 30.
- An underside 32 of the dosing head 18 is transported from left to right with the aid of a feed device 39 in FIG. 1.
- the therapeutic liquid is supplied in a dosing process, the dosing head 18 being pivoted through 180 ° around the axis 26 (arrow 36) in the exemplary embodiment shown during the supply process.
- the therapeutic liquid from the exemplary embodiment shown is dispensed through four nozzles 22.
- the dosing head is lifted using the lifting device 28 (arrow 30).
- the carrier element 34 is then moved to the right (arrow 38) in the figures in preparation for the next metering process.
- the dosing head 18 can then be lowered again and the next Dosiervor can be started.
- the dosing in each case in semicircles 40, 42 is also schematically visible on the upper side of the carrier element 34.
- a cover element is then fed in by a feed device, also not shown.
- the cover element is arranged such that the therapeutic liquid is arranged between the carrier element 34 and the cover element. In this way, with the help of a cutting or punching device, a production of in particular round products in the illustrated embodiment can follow.
