Definitions

  • the invention relates to a control device accordingly the preamble of claim 1.
  • Laboratory centrifuges are used, among other things, in medical-pharmaceutical Area used to treat mixtures by centrifugation, if necessary, according to a certain duration of treatment and a certain temperature curve. They essentially consist of a housing that can be closed by a lid, within which an interchangeable rotor is arranged, the peripheral region is also set up to interchangeably hold vessels. in which the substance mixtures to be treated are included.
  • the Rotor is connected to an electric drive and it is the overall system consisting of rotor and electric motor inside the housing arranged to oscillate.
  • each rotor, vessel and mixture of substances are specific Data in corresponding storage media of the control device entered the laboratory centrifuge, which results in accordance with the absolute scope of the data to be entered or the data to be activated or complex adjustment processes for control functions to be deactivated result that an appropriately set up the control panel Make control device necessary. This is consequently through marked a variety of switching devices.
  • Switching and input devices for data and functions is the operation of a laboratory centrifuge, especially its Change e.g. comparatively to another treatment program complicated, incorrect operation cannot be excluded.
  • a generic type for use in a laboratory centrifuge Control device is known for example from EP 0 344 453 A2.
  • This is designed as a microcomputer with a display panel and an input keyboard and other function keys is specified via which operating parameters, program sequences, etc. and in an internal computer storage device for the purpose of controlling the Operating sequence can be saved.
  • the display field is for display different operating functions, especially for visualization entered switching operations set up. It is essential here that to call up and to change the operation of the Laboratory centrifuge, namely for the purpose of adaptation to different to be treated Substances operations that involve an actuation of relative numerous function keys make it necessary, which is the danger of operating errors and in any case a relative one costly training for the operator frequently master complex setting processes safely.
  • a single control switch is provided is that for the execution of at least two, independent of each other Switching movements is set up and at least for operation a menu configuration of the display panel of the control panel is.
  • the menu field is in a known manner in panels divided, which can be individually selected using the control switch and can be activated or deactivated, whereby in connection with an appropriately set up plain text menu Setting of operating parameters and control functions themselves itself is understandable and in particular no complicated and lengthy instructions are required.
  • the switching movements can, for example, be set up such that the one switching movement for dialing and setting processes and the other switching movement set up to change or to confirm the respective switching function is.
  • Every switch comes in as a control switch Consideration of the execution of at least two mutually independent Switching movements is set up, their control engineering Implementation takes place in subordinate circuits.
  • the control switch is such a switch according to the invention, on the one hand to its Axis is rotatable and at the same time displaceable in the direction of its axis is.
  • the said rotary movement is preferably an incremental one or digitized rotary movement, so that each rotary step a selectable parameter change can be assigned.
  • the assignment of switching functions to these two switching movements is however arbitrary and can be made according to convenience become.
  • the one of the two switching movements basically for dialing movements, i.e. to the Choosing a certain button of the menu used, whereas the other switching movement to confirm or acknowledge the selected panel or the parameter value set here can be used.
  • the triggering of the latter switching movement can be used at the same time, the switching function of the former Switching movement from a previous selection process of a switch panel the setting of the parameter assigned to this panel to change.
  • control switch in a central position below the display field. This means, that despite the close proximity of the control switch and display panel, neither for Left - for right-handers the view of the display field during the Operation of the control switch is hindered. It is a preferred one Arrangement of the control switch, which is also a simple Success check of the initiated switching function using the display panel allows. Other arrangements of the control switch are possible however, the visibility on the display panel for left and Right-handers should be respected.
  • the control device thus forms an extreme easy to handle, due to a menu navigation regarding its functions self-explanatory tool for hiring operating parameters and control functions of a laboratory centrifuge, which due to the functional summary of all setting functions to a special extent in a uniform control switch is suitable to avoid incorrect operation.
  • FIG. 1 is a control device according to the invention equipped laboratory centrifuge, which means using feet 2 is supported on a base 3. It essentially exists from a globally cuboid housing 4, the top 5 by a, between a closed position shown in the drawing and an open position pivotable about a horizontal axis Lid 6 is complete.
  • the rotor and electric motor system is inside the housing hung swinging and is also not in the drawing illustrated way with a power supply and one within of the housing arranged control device in operative connection.
  • This control device has a control panel 7, which in the in the drawing shown front 8 of the housing 1 is arranged and its structure and functions explained in more detail below become.
  • the display field 9 can for example, an LCD display device.
  • the control switch 10 whose functions are explained in more detail below, is about its axis extending perpendicular to the plane of the front 8 incrementally rotatable and at the same time perpendicular to the plane of this front 8 movable, for example locked in at least two positions. Its main importance is manual adjustment of parameters of the centrifuge operation including those the rotor, the vessels used in these, the treatment program etc. to allow.
  • the switches 11 to 13 can be used as Sensor buttons may be formed, the switches 11, 12 is the on and off switch and the switch 13 by one, the locking or unlocking of the cover 6 controlling switch.
  • control switch 10 With reference to the menu configurations to be understood only as examples 2 to 14, some, control functions assigned to control switch 10 are explained become:
  • FIG. 2 to 4 show a basic menu, which the switch fields, SPEED, RZB (relative centrifugal acceleration), TIME, TEMP (Temperature), PROG (program), BES (acceleration), BRE (braking) etc. next to the SET button.
  • the assigned to these parameters the respective set values can be found in a suitable dimension within these panels. It is now essential that by turning the control switch 10, the panels are selected one after the other become. by pressing the control switch in its Axis direction the selected control field is activated and where then the value by turning the control switch again of the respective parameter is changed incrementally. Is the one you want Value is reached, the set value is confirmed by axial pressing of the control switch confirmed.
  • the SPEED field is first selected (Fig.
  • FIG. 5 shows a further menu which contains the switch fields CODE, LANGUAGE. DISPLAY, FINE, SUMMER, SENSOR, INFO, RESET shows, which in turn selectable one after the other by means of the control switch and by Presses can be actuated or activated.
  • the through the panels marked control functions are easily understandable and the dialog with the actuator is designed for the purpose Changing these control functions - e.g. the language or one Magnification of the display (zoom function) extremely easy.
  • control panel PROG programs for the treatment of substances by Centrifugation can be called, which comprise complete data sets that from the values of the speed, the relative centrifugal acceleration, time, temperature, acceleration, braking, the rotor type, the buckets used and the radius values of the rotors put together.
  • 10 and 12 show exemplary combinations of such under a program number of summarized data records under the number of a certain program can be called up. These records can can be compiled by the user and simplify parameter setting.
  • a menu field according to which the user can define it is the conditions under which an acoustic signal, here a buzz is generated. This is provided in the case by way of example only stopping of the rotor, occurrence of an unbalance, while still distinguish between a static and a dynamic unbalance and in the event of an operating error. In addition, the Summation period can still be specified.
  • control device of a laboratory centrifuge is an extremely easy to use actuation and operating system available, its functions directly through the menu are explained and its operation is based on the summary all switching movements in a control switch 10 extremely simply designed.
