Definitions

  • the invention relates to a control device according to the preamble of claim 1.
  • Laboratory centrifuges are used, among other things, in the medical-pharmaceutical field for the treatment of material mixtures by centrifugation, if appropriate in accordance with a specific duration of treatment and a specific temperature profile. They essentially consist of a housing which can be closed by a cover, within which an exchangeable rotor is arranged, the peripheral region of which is set up for likewise interchangeable receptacles in which the substance mixtures to be treated are received.
  • the rotor is connected to an electric drive and the entire system, consisting of rotor and electric motor, is arranged so that it can vibrate.
  • the laboratory centrifuge rotor respectively, vascular and stoffgemisch- specific data into corresponding storage media of the Steuerungsein ⁇ direction input, resulting in the yield or in accordance with the absolute periphery of the data to be input to activating or inactivating complex to control functions of setting operations a the control panel of the Make control device necessary. This is therefore characterized by a large number of switching devices.
  • the operation of a laboratory centrifuge in particular its conversion, for example, is also designed in accordance with the complexity of the switching and input devices for data and functions required in this context. to another treatment program is comparatively complicated, and incorrect operation cannot be excluded.
  • a single control switch for setting all operating parameters and control functions, which is set up to carry out at least two independent switching movements and which is set up to operate at least one menu configuration of the display panel of the control panel.
  • the menu field is subdivided in a manner known per se into switch fields which can be individually selected and activated or deactivated using the control switch, the setting of operating parameters and control functions being self-explanatory in conjunction with a correspondingly configured plain text menu and in particular, no complicated and lengthy instructions are required.
  • the switching movements can, for example, be set up in such a way that one switching movement for dialing and setting processes and the other switching movement for changing or for confirming the respective switching function is aimed.
  • any switch which is set up to carry out at least two mutually independent switching movements can be considered as the control switch.
  • the features of claim 2 are directed to a particularly advantageous embodiment of the control switch mentioned. It is a switch of this type, which on the one hand can be rotated about its axis and at the same time can be displaced in the direction of its axis.
  • the said rotary movement is preferably an incremental or digitized rotary movement, so that a selectable parameter change can be assigned to each rotary step.
  • the assignment of switching functions to these switching movements is arbitrary and can be carried out from the point of view of expediency.
  • the features of claim 3 are directed to an expedient way of assigning switching movements and switching functions in connection with menu navigation.
  • one of the two switching movements can in principle be used for dialing movements, ie for selecting a specific switching field in the menu, whereas the other switching movement can be used to confirm or acknowledge the selected switching field or the parameter value set here.
  • the triggering of the last-mentioned switching movement can simultaneously be used to change the switching function of the first-mentioned switching movement from a previous selection process of a switching field to the setting of the parameter assigned to this switching field.
  • separate switches are provided only for switching on and off and for locking the lid of the housing of the laboratory centrifuge, thus for comparatively simple functions. With regard to the existing switching functions, there is thus a complete decoupling in terms of operation between those which serve to set operating parameters, programs, control functions and the like and which are only aimed at starting up the laboratory centrifuge or at stopping operation.
  • control switch is in a central position below the display panel. This means that despite the close proximity of the control switch and display panel, the view of the display panel is not obstructed by left or right-handed people while the control switch is actuated. This is a preferred arrangement of the control switch, which at the same time enables simple monitoring of the success of the initiated switching function on the basis of the display field. Other arrangements of the control switch are possible, but good visibility should be maintained on the display panel for left-handed and right-handed users.
  • the control device thus forms an extremely easy-to-use, self-explanatory tool for setting operating parameters and control functions of a laboratory centrifuge due to a menu navigation, which is particularly suitable for avoiding incorrect operation due to the functional combination of all setting functions in a uniform control switch .
  • FIG. 1 shows an illustration of the front view of a laboratory centrifuge with a control panel according to the invention
  • FIG. 1 denotes a laboratory centrifuge equipped with a control device according to the invention, which is supported on a base 3 by means of feet 2. It essentially consists of a globally cuboid housing 4, the upper side 5 of which is closed by a cover 6 which can be pivoted about a horizontal axis between a closed position shown in the drawing and an open position.
  • a rotor which is set up in the peripheral area for the releasable reception of vessels and is rotatably mounted about a vertical axis and is in rotary connection with an electric motor.
  • the system of rotor and electric motor is suspended within the housing so that it can vibrate and is also not shown in the drawing with a power supply and one inside of the housing arranged control device in operative connection.
  • This control device has a control panel 7, which is arranged in the front 8 of the housing 1 shown in the drawing and whose structure and functions are explained in more detail below.
  • a display panel 9, a control switch 10 and further switches 11 to 13 are integrated into the control panel 7.
  • the display panel 9 can be an LCD display device, for example.
  • the control switch 10, the functions of which will be explained in more detail below, can be rotated incrementally about its axis extending perpendicular to the plane of the front side 8 and at the same time can be moved perpendicularly to the plane of this front side 8, for example locked in at least two positions. Its essential importance is to enable the manual setting of parameters of the centrifuge operation including those of the rotor, the vessels used in them, the treatment program etc.
  • the switches 11 to 13 can be designed as sensor buttons, the switches 11, 12 being the on and off switch and the switch 13 being a switch which controls the locking or unlocking of the cover 6 acts.
  • the display field 9 has a menu-like individual switch fields marked area, which switch fields can be selectively actuated by actuating the control switch 10 and the switch fields are each assigned defined switching functions or parameters of the centrifuge operation.
  • the rotary movement of the control switch 10 is assigned two functions, namely on the one hand the selection of a specific switching field of the display field 9 and the selection of a specific value of the respectively selected parameter or the selection of a specific function within the selection range assigned to the switching field.
  • the switchover between these two functions of the control switch is carried out by a switching movement initiated by the user in its axial direction.
  • the meaning of all panels is identified by plain text so that their meaning for the user is self-evident and requires no special explanation.
  • the display field 9 also serves to signal fault messages and the current operating states of the centrifuge. These functions can also be called up on the display panel via the control switch 10, so that, if necessary, it is also possible to intervene in the centrifuge operation depending on the information obtained in this way. Safety functions are thus equally integrated in the control device mentioned. This is therefore a dialog-capable, self-explanatory system, which significantly simplifies the operation of the centrifuge and, in principle, is also suitable for preventing incorrect operation by recognizing it and signaling it either optically and / or acoustically.
  • 2 to 4 show a basic menu which shows the control fields, SPEED, RZB (relative centrifugal acceleration), TIME, TEMP (temperature), PROG (program), BES (acceleration), BRE (braking) etc. next to the SET control panel .
  • the values set and assigned to these parameters can be found in a suitable dimension within these switch fields.
  • control fields are selected one after the other by turning the control switch 10, wherein the control field selected in each case is activated by pressing the control switch in the axial direction thereof, and the value of the respective parameter is subsequently changed incrementally by turning the control switch again .
  • the set value is confirmed by pressing the control switch axially again.
  • the SPEED field is first selected (FIG. 2), then confirmed by pressing the control switch, whereupon the speed is changed from 2000 to 3460 (FIG. 3) and then confirmed by pressing the control switch again (FIG 4).
  • the parameters appearing in bold represent current measured values.
  • the activated field SET signals the confirmation of the setting process.
  • Fig. 5 shows another menu, which the buttons CODE, LANGUAGE. DISPLAY, FINE, SUMMER, SENSOR, INFO, RESET shows, which in turn can be selected one after the other using the control switch and can be actuated or activated by pressing.
  • the control functions identified by the control fields are easy to understand and the dialog with the actuating device is extremely simple in order to change these control functions - for example the language or to enlarge the display (zoom function).
  • Programs for the treatment of substances by centrifugation can be called up via the PROG button, which include complete data sets, which are based on the values of the speed, the relative centrifugal acceleration inclination, time, temperature, acceleration, braking, the type of rotor, the buckets used and the radius values of the rotors.
  • 10 and 12 show exemplary compilations of such data sets combined under a program number which can be called up under the number of a specific program. These data records can be compiled by the user and simplify parameter setting.
  • FIG. 14 shows a menu field according to which the user can define the conditions under which an acoustic signal, in this case a buzz, is generated.
  • an acoustic signal in this case a buzz
  • Operating errors can occur, for example, if the speed at which a rotor inserted in the centrifuge is to be operated is above its maximum permissible speed. The latter depends on the particular type of rotor, but equally on the type used in these vessels containing the substance to be treated by centrifugation. The specific function assignment to the above-mentioned panels is only to be understood as an example. It is also possible to provide a large number of menus, each with control fields, which can be activated in succession by repeatedly pressing the control switch. In conjunction with a corresponding menu design, it is also possible to provide a coding which makes the change in operating parameters of the centrifuge dependent on the previous input of a code, so that a change in these operating parameters is at least made more difficult by unauthorized persons.

Abstract

L'invention concerne un dispositif de commande destiné à simplifier l'utilisation, notamment en vue de l'introduction précise de données propres au rotor, au récipient ou au mélange de substances, dans le support de mémoire correspondant. Le clavier d'exploitation (7) est pourvu d'un interrupteur de commande (10), en dessous d'un pupitre de visualisation (9) configuré pour assurer une représentation visuelle d'au moins une partie du paramètre de fonctionnement du moment de la centrifugeuse de laboratoire. Cet interrupteur de commande est destiné à ajuster tous les paramètres de fonctionnement et les fonctions de commande du fonctionnement de la centrifugeuse. L'interrupteur de commande (10) est configuré pour au moins deux mouvements de commutation indépendants les uns des autres, notamment un mouvement de rotation autour de son axe et un mouvement de déplacement dans le sens de cet axe, ces deux mouvements de commande permettant d'utiliser une configuration de menus représentant les paramètres de fonctionnement et les fonctions de commande du fonctionnement de la centrifugeuse. Comme la sélection et la modification des paramètres de fonctionnement et des fonctions de commande sont associées à un des mouvements de commutation et que la confirmation de la sélection et celle de la modification d'ajustement correspondante sont associée à l'autre mouvement de commutation, on obtient un dispositif de commande d'utilisation extrêmement aisé et fiable, qui fournit à chaque utilisateur des explications concernant ses fonctions en relation avec une commande des menus et informe immédiatement en particulier du succès ou de l'insuccès de la fonction de commande introduite par l'interrupteur de commande (10).
