Definitions

  • the invention relates to a method for operating an electronic dosing system with an electronic hand dosing device and to a dosing system for carrying out the method.
  • Dosing devices are used in laboratories for dosing liquids. They are known in different versions. Dosing devices operating on the principle of the air cushion have an integrated piston-cylinder unit, by means of which an air column can be displaced in order to suck in and eject sample liquid into a dosing tip. In this case, the piston-cylinder unit does not come into contact with the liquid. Only the dosing tip, which is usually made of plastic, is contaminated and can be replaced after use.
  • a syringe In direct displacement metering, however, a syringe is filled directly with sample liquid. Piston and cylinder of the syringe are so contaminated by the liquid, so that the syringe usually has to be replaced or cleaned by a new syringe before changing the liquid.
  • the syringe is usually made of plastic.
  • Microdosing devices may have a micromembrane pump and / or a free jet dispenser, wherein at least one of these components is designed microsystem technology, in particular in silicon, glass, plastic injection molding and / or plastic embossing technique.
  • the dosage is achieved by deformation of a wall of a chamber which is filled with liquid.
  • the electric drive for deforming the wall may be piezoelectric, thermoelectric, electromagnetic, electrostatic, electromechanical, magneto-restrictive, etc.
  • Air-cushion, direct-displacement, piston-less and micro-metering devices may have a fixed or variable metering volume.
  • a change in the metering volume is achieved by adjusting the displacement of the displacement device, d. H. the displacement of the piston or the degree of deformation of the balloon-like end portion or the chamber wall.
  • Dispensers are dosing devices that can deliver a recorded volume of liquid repetitively in small quantities.
  • All dosing devices can be designed as handsets.
  • All of the aforementioned metering devices may be electronic metering devices of an electronic metering system in the sense of this application.
  • they have a drive device with an electric drive for driving the displacement device.
  • they have an electronic control and / or regulating device, in particular for the drive, which may be an electric drive motor, an electric linear drive or one of the drives mentioned in connection with microdosing devices.
  • they have an electrical voltage source for supplying control and / or regulating device and drive, which can be rechargeable.
  • Electronic metering devices have the advantage of high reproducibility of dosages.
  • pre-set dosing speeds ( ⁇ / s) can achieve more accurate results than with manually driven devices.
  • they can have the benefit of multi-functionality, as they can perform pipetting, dispensing, titration, mixing, etc. functions.
  • Applicants' known electronic hand dispensers Response® operate on the air-cushion principle and are available in single-channel or multi-channel designs. Four models cover the dosing range from 0.5 ⁇ l to 5 ml.
  • This metering device can operate in various modes, i.a. pipette and dispense. Dispensing is possible in up to 25 steps. The user can choose between three different dosing speeds.
  • the metering device can be used for charging the battery cells in a charging station.
  • EP 0 864 364 A2 discloses a similar electronic manual dosing device with rechargeable batteries and a charging station for charging them.
  • the handheld dosing device may be operated in various modes including hands-free operation other than pipetting and dispensing.
  • the manual dosing device is programmed to control the aspiration, dispensing, and time delays to exchange or treat the dosing tip. It executes these program steps over a specified number of cycles.
  • the previously known electronic manual dosing devices have the disadvantage that the specific operating parameters (eg step widths of the piston feed, metering speeds, state of charge criteria, display outputs) and the program are predefined.
  • the electronic control device comprises a microcomputer which operates according to a permanently stored program in which these parameters are contained.
  • a special software is required for each model and a subsequent change of the parameters hardly possible.
  • the programming of the freehand operation must be carried out laboriously on the keyboard of the manual dosing and that in the freehand mode, the programmed steps are executed rigidly and the operation is not influenced.
  • Dosing devices are test equipment within the meaning of the GLP (Good Laboratory Practice) guidelines and comparable QA standards (ISO 9000 ff, EN 45000 ff). According to the GLP guidelines, the error limits published by the manufacturer must be checked at regular intervals. By the applicant, a system has become known, with which the calibration of metering devices can be done quickly, conveniently and inexpensively.
  • This system is based on a calibration software PICASO®, which runs on a PC.
  • a measuring structure is required, which includes weighing containers, adapters and carrier sleeves as well as an evaporation trap and a semi-microbalance. All relevant data of the dosing devices to be tested are stored in the software. Deviations from these nominal values are determined immediately after transfer of the weighing values to the computer. A series of measurements covers up to 15 individual weighings. From this mean value, incorrectness, imprecision and standard deviation are determined and compared with predetermined target values. All measurement and reference data can be logged in accordance with GLP-DIN.
  • the dosing data are entered and their operation is controlled via the control panel of the electronic manual dosing device.
  • the weighing values are typed into the PC. This is troublesome and can lead to mistakes.
  • a method for filling and emptying a pipette with quantitative accuracy in which the distance traveled by a piston path is measured during the movement of the piston and the piston is stopped when a distance corresponding to the desired amount of liquid has been achieved has been achieved.
  • a pipette with elements for measuring the piston stroke and elements for controlling the movements of the piston is known.
  • the pipette has a data input device, such as a keyboard, a display and an interface.
  • the data input device serves to supply the control device with data or commands.
  • the display is used to display the entered data and / or the steps performed.
  • the interface allows the controller to be connected to an external device, for example for data transmission or data processing.
  • the object of the invention is to provide a method for operating an electronic dosing system in which the ability to influence programs is improved.
  • advantageous metering systems are to be provided for carrying out the method.
  • the external data processing system can be used to access the read-write memory of the manual dosing device.
  • routines for the execution of operating sequences in the read-write memory of the manual dosing device by means of the external data processing system so that the program-controlled electronic control and / or regulating device makes use of it.
  • routines can be created by the user and serve to control operations composed of multiple operations, especially if they are to be repeated. For example, by means of such a "short program" it is possible to control the picking, mixing and dispensing of specific quantities of liquid or a series of dilutions in which the dispensing volume dispensed is halved from one dilution step to the next. This facilitates the use of routines for the user.
  • the memory is preferably a flash memory of a processor.
  • a flash memory processor has implemented a proprietary program that can initiate communication for data exchange over an interface. This makes it possible to load a partially or completely different program from the outside via the data interfaces into each hand-dose device or to change the program completely or partially.
  • These may be device-type-specific parameters, in particular those that are intended for carrying out operating procedures.
  • these may be the parameters of the movement of the piston of a displacement device (eg acceleration characteristic, piston speed, driving force, holding torque).
  • these may be, for example, quantity-determining parameters (for example: basic values and limit values of metered quantities, possible numbers of metering steps, overspill volume for discharging residual liquid).
  • other device-type specific parameters may relate to the monitoring of operating conditions (eg, evaluation criteria for the state of charge of an accumulator, for the actuation of a limit switch or for the duration of a rest in order to switch off to a "sleep state").
  • Device-specific parameters can be, in particular, an identification of the device, an identification code for a respectively stored parameter set, etc.
  • User parameters are data that can also be input manually by the user via a keyboard of the manual dosing device. These include, in particular, the metering volume, metering rates, etc. Further application parameters relate to the calibration of the manual metering device. In a simple case, this may be a correction factor for the conversion of the set dosing amounts to the actually dispensed dosing quantities. In particular, these may also be coefficients of a function which includes the deviation of the set metering quantities actually delivered with different quantity settings.
  • a remote control of the manual dosing device is possible.
  • This favors, in particular, the calibration by transferring the respective dosing data to the manual dosing device by means of the data processing system and, if appropriate, by completely controlling the operation by means of the data processing system.
  • the data processing system can log the respective dosing data. Optionally, this can be done together with the respective measured values, if they are detected and recorded in the data processing system.
  • a wired or a wireless remote control of the manual dosing device take place. This favors, in particular, an automation of the dosing operations, the use of the manual dosing device in a higher-level automation process or a safe dosing in a contaminated environment.
  • the invention makes it possible to determine the specific parameters of the metering device only after the device assembly, even if this includes the installation of a block with permanently programmed software. This makes it possible to use the same software and electronic hardware for different device models.
  • the respective parameters can be set as required or even changed.
  • a device-type-specific or device-specific definition or modification of program parts or of the entire program is possible.
  • the storability of user parameters by means of an external data processing system creates an additional, advantageous operating option.
  • the invention favors automation of calibration and final inspection in manufacturing. The service will be able to easily update to new operating parameters.
  • the OEM customer can in turn carry out a parameterization for special OEM metering parts. The user is facilitated the GLP parameter documentation and a simplified calibration with a PC software is made possible.
