Definitions

  • the present invention relates to 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 invention also relates to a method for operating such a program-controlled agitator.
  • compositions of ointments, powder mixtures, gels and the like are produced on medical prescription.
  • the components of the formulation are manually mixed with one another according to the conventional method.
  • mortar and pestle or glass plate and spatula can be used.
  • the conditions under which the individual substances are mixed cannot be reproduced and cannot be documented. If several recipes of the same type are produced, this can result in significant quality differences, which can have an impact on the effectiveness of the recipe.
  • an agitator (which can also be referred to as an agitator) has an agitator unit and a lifting unit in order to determine in a partially automated manner with an agitator 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 different mixing processes are not available over a longer period of time and therefore have to be re-entered.
  • DE 39 19 534 AI shows a method and a device for preparing bone cement. According to this method, 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 ensured and the Repeatability for identical mixtures cannot be guaranteed either.
  • DE 43 02 085 Cl specifies a method for metering and mixing tooth fillers consisting of several components and a device for carrying out the method.
  • a program-controlled agitator in which the agitator unit is coupled to a microprocessor, which program-controlled determines the agitation time and agitation speed of the agitator unit, a data processing program executed by the microprocessor comprising the following steps:
  • the main advantage of the agitator according to the invention is that a GMP-compliant quality uniformity of the recipes to be produced can be largely guaranteed. It is ensured that similar recipes are produced with the same mixing conditions. In addition, errors in the operation of the agitator are largely excluded.
  • An advantageous embodiment of the program-controlled agitator also contains a lifting unit, by means of which the relative position of the agitating tool in the mixing vessel can be changed during the agitation process, the data processing program executed by the microprocessor further comprising the following steps:
  • 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 stirring method 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 that can be carried out by the stirring tool in the mixing vessel.
  • variable data on the viscosity of the starting materials are also read in via the data input means. If required, 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 stirrer 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 stroke 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 at a later point in time the specially used control parameters can be accessed via the individualization data if an identical recipe is to be produced again.
  • a further 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 quickly called up from the data memory for later recipes of the same type.
  • an output unit is also provided, via which the applied control parameters 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 if the used packaging unit is requested again 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.
  • Fig. 1 is a block diagram of a program-controlled agitator
  • Fig. 2 is a flowchart of the displays of the agitator during a mixing process.
  • the actual mixing device consists of a stirring unit 1 and a lifting unit 2. Via these two units, a stirring tool is driven 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 exchanged, for example if different sizes of mixing vessels are used.
  • Stirring unit 1 and lifting unit 2 interact 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.
  • the program-controlled agitator also has a microprocessor 5, which takes over the control of the agitation 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 for the stirring unit 1 and the lifting unit 2 supplied by the microprocessor 5 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 continue with a higher speed of the stirring tool in order to 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 memory 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 memories 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 which the program-controlled agitator carries out are explained below, the control of these method steps being carried out by the data processing program which 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 started up beforehand 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 stored 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 uniquely assigned to the control parameters used. All essential data is 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 rubbing process, which is also indicated in the batch designation by the “AR” indicator.
  • the display that appears during the grinding process is shown.
  • the speed of rotation that corresponds to the special type of the product to be manufactured is coordinated The case is 1,000 revolutions per minute (Rp).
  • Rp revolutions per minute
  • the "normal" mixing process begins and the display changes to the state shown in step 30.
  • the control parameters used are stored and / or output, for example encrypted in the identification data, printed on a label, and after the mixing process has been completed, the display returns to step 10, so that the user can correctly complete the process You can also check the recipe in the display.Of course, it is also possible to generate a changed final display in which the user is informed in a summarized form of the successful completion of the mixing process.
  • a final rapid homogenization process can take place after a first mixing section. In this way, the total time for producing 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.
