Definitions

  • the present invention relates to a method for using a program-controlled stirrer for the production of pharmaceutical or cosmetic formulations or the like, with a speed-controlled electrical stirrer unit which comprises a stirrer tool which engages in a mixing vessel, the stirrer unit being coupled to a microprocessor which program-controlled stirrer time and stirring speed of the stirring unit.
  • a device for stirring, mixing, crushing or the like is known.
  • Such a device (which can also be referred to as an agitator) has a stirring unit and a lifting unit in order to determine in a partially automated manner with a stirring tool in a mixing container Mix substances so that the result is the desired recipe.
  • this device it is possible to change the stirring speed, the stirring time, the number of strokes and the lifting speed manually within certain limits in order to optimally adapt them to special types of recipes.
  • These parameters of the agitator must be adapted to the properties of the starting materials and the respective amounts of these substances if the result of the mixing process is to be satisfactory.
  • the disadvantage of this known device is that the optimal parameters of various mixing processes are not available over a longer period of time and therefore have to be re-entered. Individual entries of the mixing time, the number of revolutions per minute of the mixing tool, the stroke speed and the number of strokes cannot easily be reproduced at a later point in time. Special formulations can therefore vary greatly in quality both in the manufacture in different pharmacies and in the repeated manufacture in one and the same pharmacy at different times. Quality uniformity (Good Manufacturing Practice - GMP) cannot be guaranteed for the same medical prescription.
  • DE 39 19 534 A1 shows a method and a device for preparing bone cement.
  • an automatic process control is provided, the mixing phase and / or the resting phase being selected taking into account the type of the respective bone cement and its amount used.
  • the operation of the device described is relatively complex since the control parameters have to be entered manually.
  • the documentation of the mixtures carried out is not guaranteed and the Repeatability for identical mixtures cannot be guaranteed either.
  • a method for controlling stirring processes is known from DE 31 26 552 A1.
  • the optimum power consumption of the agitator is regulated based on the viscosity of a substance.
  • the viscosity can be continuously determined during the stirring process.
  • the repeatable, documentable and rapid production of mixtures using the parameters resulting from container sizes is not important.
  • DE 43 02 085 C1 specifies a method for metering and mixing tooth fillers consisting of several components and a device for carrying out the method.
  • Another task is to simplify the use of agitators so that cosmetic and pharmaceutical products can also be manufactured in the required quality by less qualified personnel.
  • the invention is intended to enable an individual formulation to be produced with the same quality even at longer time intervals and to permit an increase in effectiveness when such formulations are produced several times.
  • the main advantage of the method according to the invention is that a GMP-compliant quality uniformity of the recipes to be produced can largely be guaranteed. It is ensured that similar recipes are produced with the same mixing conditions. In addition, errors in operating the agitator are largely excluded.
  • the inclusion of the lifting unit in the control by the microprocessor further increases the quality uniformity required by the pharmaceutical law. It also makes it possible to adapt the method of stirring to the special starting materials and the desired end product.
  • stirring in this context also means the comminution of the starting materials, the mixing and blending of the starting materials and all other processing operations that can be carried out by the stirring tool in the mixing vessel.
  • stirring tool By using the program-controlled stirring tool, ointments, gels and other pasty masses can be produced. In addition, powdery individual substances can be mixed together if this is necessary for the specified recipe.
  • Various stirring tools can be used, the size and shape of which are adapted both to the mixing vessel and to the stirring task to be performed.
  • variable data about the viscosity of the starting materials are also read in via the data input means. If necessary, further substance-describing data or default values for the stirring time, the stirring speed, the number of strokes and the lifting speed can be entered.
  • the program-controlled agitator compares these default values with minimum values stored in the data memory and applies these minimum values if the default values fall below the minimum values. A gross incorrect operation of the agitator is therefore excluded, which ensures a minimum quality of the respective recipe by using the minimum values.
  • a particularly preferred embodiment of the method enables the control parameters used during the preparation of the recipe to be stored, ie either the stirring time, the stirring speed, the number of strokes and the lifting speed or the determined current or voltage values for controlling the stirring unit and / or the lifting unit.
  • This data is linked to individualization data, so that the control parameters used in particular can be accessed at a later point in time if an identical recipe is to be produced again.
  • Another advantage of this measure is that it saves a considerable amount of time, since the control parameters for the agitator only have to be entered once and can be called up quickly from the data memory for later recipes of the same type.
  • an output unit is also provided, via which the control parameters used and, if necessary, also the identification data can be output.
  • the identification data can be printed on a label which is attached to the packaging unit of the recipe produced. This means that the identification data are available when the used packaging unit is re-requested for the same recipe.
  • the data can also be output in electronic form.
  • the data could be encoded in a bar code so that all control parameters can be read in again with a scanner. This would also enable the uniformity of production in different pharmacies, since not only the identification data but also the complete control data can be encoded in the bar code.
  • the program-controlled agitator is set up as a stand-alone device, a keyboard, a touch-sensitive screen or a similar data input means is provided in order to feed the variable data.
  • a data connection to a personal computer which is available for data input, data output and also for data storage.
  • the data connection can take place, for example, via a serial interface. This is particularly advantageous since conventional computers can be used in this way, which are equipped with a special control program.
  • the actual mixing device consists of a stirring unit 1 and a lifting unit 2.
  • a stirring tool is driven via these two units, which interacts with a mixing vessel.
  • the stirring tool is adapted to the size of the mixing vessel in order to achieve optimal stirring results.
  • the stirring tool can preferably be replaced, for example if different sizes of mixing vessels are used.
  • Stirring unit 1 and lifting unit 2 work together in such a way that the stirring tool is rotated in the mixing vessel and that the relative position between the stirring tool and the mixing vessel changes so that the stirring tool can mix well all areas within the mixing vessel. For this purpose, it is possible both to change the vertical position of the stirring tool and to achieve the vertical movement by moving the mixing vessel when the stirring tool is stationary.
  • the program-controlled agitator also has a microprocessor 5, which controls the stirring unit 1 and the lifting unit 2.
  • the microprocessor 5 executes a data processing program, the individual method steps of which are explained in more detail below.
  • the control data supplied by the microprocessor 5 for the stirring unit 1 and the lifting unit 2 are converted in a conventional manner into current or voltage values, for which purpose known circuit elements (not shown) are used.
  • the microprocessor 5 can access a data memory 7 in order to load predetermined constant data and / or to store determined control data for a later mixing process.
  • the microprocessor 5 interacts with data input means 8 and data output means 9. Variable data can be entered by the user via the data input 8.
  • the user can specify the amount of the recipe to be produced (for example a suspension ointment), the desired stirring time and the desired number of revolutions of the stirring tool.
  • the size of the mixing vessel used there are input options for the size of the mixing vessel used, so that the optimum control values for the agitator can be determined from this information.
  • the microprocessor 5 links the variable data entered via the data input means 8 with the constant data which are stored in the data memory 7. The variable data are compared with minimum values and with maximum values, which specify the possible limit values for the stirring speed, the stirring time, the lifting speed and the number of strokes.
  • the stirring process does not have to be carried out with constant control values over the entire time. Rather, it makes sense for certain substances to start with a slow stirring speed and then to continue with a higher speed of the stirring tool to achieve optimal mixing results. After a so-called rubbing process, the speed of the stirring tool can be increased in order to produce a uniform mixing as quickly as possible.
  • the microprocessor 5 can output the control parameters used via the data output means 9.
  • the data output means 9 can comprise a display which shows both the current operating state and the control parameters to be used during the mixing process.
  • a printer or an external data storage device can be assigned to the data output means 9 in order to store the control parameters in printed form, for example on the label of the recipe produced, or on external electronic data storage devices for later use.
  • FIG. 2 shows a sequence of reproductions of a display unit of the data output means during a mixing process which is carried out by the program-controlled agitator. Based on this display sequence, the essential steps that the program-controlled agitator carries out are explained below, the control of these method steps being carried out by the data processing program that is executed on the microprocessor.
  • a suspension ointment with an amount of 50 ml is to be produced.
  • step 10 the display is shown when the data entry is complete.
  • the agitator is first put into operation and the required data is entered by the user via the data input means in step 11. At least the amount of the suspension ointment to be produced is to be entered, with additional data optionally being able to be entered, for example the desired duration of the stirring process.
  • the data processing program is able to independently determine all further data from the amount of the recipe to be produced. In this case, stored default values for the stirring time, the stirring speed, the lifting speed and the number of strokes are used.
  • the manufacturer of the program-controlled agitator can permanently read the default values into the data memory. However, there is also the possibility that the default values can be saved by the user in a programming mode if this appears expedient for certain applications.
  • the recipe number and, if necessary, a batch name can be entered or specified by the data processing program. Such data are used as identification data, which enable the mixing process carried out to be clearly assigned to the control parameters used. All essential data are encoded in the batch name, for example the type of recipe (normal, emulsion, suspension, reaction mixture, powder or the like) and special specifications for the stirring process (e.g. with grinding process in the manufacture of suspensions).
  • the mixing process begins.
  • the mixing process begins with a grinding process, which is also indicated in the batch designation by the "AR" indicator.
  • Step 20 shows the display that appears during the rubbing process.
  • the speed of rotation is also displayed, which is matched to the special type of product to be manufactured. In the present The case is 1,000 revolutions per minute (rpm).
  • the number of revolutions and the number of strokes carried out as well as the remaining mixing time are also specified.
  • the "normal" mixing process begins and the display changes to the state shown in step 30.
  • the current speed of rotation, the number of revolutions to be carried out, the number of strokes to be carried out by the agitator and the remaining time for the current mixing process are also displayed here.
  • the control parameters used are stored and / or output in step 31, for example encrypted in the identification data and printed on a label.
  • the display returns to step 10 so that the user can also check the correct completion of the recipe in the display.
  • a final rapid homogenization process can take place after a first mixing section. In this way, the total time for the preparation of the recipe can be significantly reduced.
  • a corresponding agitator is preferably equipped with specially predetermined mixing vessels (so-called jars), a certain number of revolutions that the mixing tool has to carry out can be specified for each size of a mixing vessel. It is therefore sufficient if the user feeds the jar size via the data input means.
  • sensors are attached which automatically detect the jar size, so that this data entry is also automated without any direct action by the user.
