Definitions
- the present patent application relates to a manually operated repetitive one Dispensing and / or receiving device for liquids with the features the preamble of claim 1.
- the teaching of the invention relates generally to the handling of liquids. Initially, this can involve dispensing liquids a corresponding delivery device in a metered manner from a previously recorded larger volume of liquid or from another stored Act liquid volume. But it can also be controlled Activate absorption of liquid subsets from liquid volumes. Finally, it can also be a combination of both methods, that is, both absorption and delivery of liquid portions. The latter can also be in a recurring cycle of intake / delivery or intake / movement / delivery expire.
- the teaching of the present patent application is primarily based on Dispensing facilities described. This is for easier understanding of the Operation of the device described. Regardless, the teaching is The present patent application is broad for all types of liquid handling can be used when dispensing and / or taking up liquids.
- Dispensing devices of the type in question are, for example, direct displacement or repeating pipettes with an air cushion for a pipette system or directly displacing or with air cushion displacing dosing devices of a dosing system.
- Hand-operated repeating pipettes are hand-operated pipettes with one attached, large-volume syringe from which by actuating the actuating element each metered a small portion into a receptacle can be.
- Repeating pipettes are used for screening in particular in connection with a variety of receptacles, often with so-called Titer plates.
- the usual volumes to be pipetted that is to say dosing quantities, are, for example at 100 ⁇ l to 500 ⁇ l, a typical syringe then, for example, one Filling quantity that corresponds to 10 to 100 times the desired dosage.
- An electric repeater pipette has due to the electric motor Drive is particularly easy to use.
- the one for control of the electric motor drive existing control electronics offers the Possibility to not only precisely specify the dosing quantity, but also one Dosing interval for a large number of doses to be carried out one after the other to be able to specify identical dosing quantities.
- This is done with such a Repeater pipette (direct displacement) known in practice by means of programming buttons the desired dosing interval in a setting range from 0.1 to 1.0 sec, setting steps of 0.1 sec are specified.
- one is as Air-cushion pipette repeater pipette provided at which a dosing interval between 0.1 sec and 10.0 sec can be entered.
- a pipetting device with a memory function is known (DE 44 36 595 A1).
- This Pipetting device has a programming element that has a manual position, a memory setting position and can assume a storage operating position. is If the programming element is in the memory setting position, actuation leads of the actuating element so that one by the operator determining storage volume can be recorded (or released). This storage volume specified by the operator is in the Control electronics memory stored. Then the programming element switched to the storage operating position, a subsequent one leads Actuation of the actuating element by hand to ensure that the delivery (or absorption) of a liquid quantity of the previously stored value automatically he follows. The actuation of the actuating element is then only used the triggering of the submission step or admission step, no longer the determination its duration.
- the teaching is based on the problem of a delivery and / or reception facility to indicate for liquids of the type in question which handling is further improved.
- the core of the teaching is the control electronics as a self-learning system embody.
- the control electronics do not require any presetting of the Process interval by the operator. The operator must rather just start handling, just in the form of individually triggered Process steps, and until the operator yours to this Found a personal rhythm at the time. Change the Operator then from the first type of actuation of the actuator to the second type of actuation of the actuating element, so the Control electronics automatically continue the process steps at the process interval that arises from the time intervals of the previous individual process steps.
- the teaching of the invention is based on a delivery device for Liquids further explained with the actuation of the actuating element a certain metered amount can be metered by a motor into a receptacle. regardless this applies to the general applicability already mentioned several times the inventive device for handling liquids for all types of dispensing and absorption of liquids.
- actuating the actuating element is to be understood generally.
- an actuating element designed as a pushbutton it should on the one hand include the normal case that pressing the button of the Operation corresponds.
- a release of the actuation button is also intended with the appropriate design of the control electronics, the function of Fulfill actuation of the actuating element. So you would have the actuator constantly pressed during single dosages and would use it for only release the individual doses briefly, then continuously if you keep pressing them let go.
- a double key would also be conceivable as an actuating element with a Key for single dosing and a second key for automatic dosing. Operation by computer type with one click (for single operation) and double click (for continuous operation) you can imagine.
- actuation is synonymous with influencing or not influencing.
- Optical actuating elements are also of particular interest a light barrier switch.
- Trigger interval is the interval between the start of an operation of the actuating element and the beginning of the next following actuation of the Actuator. This is also referred to in the text as the time interval between each Operations of the actuator designated.
- Process interval is the time interval between the start of a process step and the beginning of the next process step.
- the remaining interval is the time interval between the end of a process step and the beginning of the next process step.
- the device shown in FIGS. 1 and 2 is a delivery device in Form of a repeater pipette 1. It is intended for a hand-operated one Pipette system with such a repeater pipette 1 and an interchangeable one attached syringe 2, the filling quantity is so large that from this syringe 2nd in a multitude of individual steps, small dosing quantities into a multitude can be dosed from receptacles.
- FIG. 3 shows in the manner of a block diagram the scheme of the invention Dispensing device 1.
- FIG. 3 is intended for understanding in the explanation of FIG. 1 and 2 can also be used.
- the device 1 according to the invention can be repeating pipettes 1 act as direct displacers or as bubble wipers as well as dosing devices such as bottle dispensers or bottle titrators. Following the delivery device 1 is based on the example of a repeater pipette 1 in the form of a direct displacer explained, without this being understood as restrictive. The applications explained in the general part of the description apply when picking up and / or dispensing liquids.
- An example of a stationary Dosing device is, for example, in the publication already mentioned at the beginning "Compudil" presented, the content of which by reference to the content of the present Patent application is made.
- the dispenser 1 shown initially has a housing 3 - pipette housing - And therein an actuating device 4.
- a repeater pipette as a delivery device 1, designed as a direct displacer, is the actuating device 4 around a piston adjusting device with which a piston, not shown the syringe 2 for the purpose of single metering certain dosing amounts can be advanced gradually.
- To operate the actuator 4 serves an electromotive drive 5, which in turn is controlled by control electronics 6 is controlled.
- control electronics 6 is controlled.
- other motor drives can also be used, however, an electric motor drive 5 is particularly practical.
- Fig. 1 you can see 3 handle shapes 7 for safe detection on the housing the repeater pipette 1, and an actuating element 8, which is the one Repeater pipette 1 holding hand of an operator is to be operated.
- This Actuator 8 has the shape of a in the illustrated embodiment Actuating button. But you can also other actuators 8, for example realize an operating rocker switch or the like.
- the actuator 8 is used to operate the control electronics 6. If it is operated, then the electromotive drive 5 is briefly controlled by the control electronics 6 and effects the desired adjustment of the adjusting device 4.
- an embodiment of the actuating element is also particularly expedient 8 as not mechanical, but purely electronic, and preferably non-contact element.
- Fig. 1 shows on the right in a dashed outline an actuator is based on the principle of operation of an interrupt light barrier. By Pressing on a cover plate 8 '' 'interrupts the light barrier is the actuation signal of the actuation element. Such a signal is for evaluation purposes more convenient to handle in the control electronics 6 because a clear switching threshold can be specified. In contrast, mechanical Bouncing switch.
- a programming element 9 for the control electronics is also located on the housing 3 6. This is in the illustrated embodiment on the the actuating element 8 opposite side of the housing 3.
- the programming element 9 for the control electronics 6 has in the illustrated embodiment on the one hand a display area in the form of the display 10, on the other hand several programming buttons 11. The only thing that matters is that these There is a programming device, how it is designed in detail, for a specialist of average skill results from his specialist knowledge.
- the repeater pipette 1 in FIGS. 1 and 2 Receptacles 12 which in the exemplary embodiment shown are in an 8 ⁇ 12 (96) Titer plate 13 are summarized. There are of course many different ones here too Variants.
- a process step can also consist of several individual steps, for example from the sequence of an admission step, a transport step and one Dispensing step. In the present embodiment, it remains with the Explanation of a dispensing step.
- the present technique is about how the process interval t p is found.
- the process interval t p is set by means of the programming element 9, for example to a value of 0.4 sec.
- setting steps of 0.1 sec to 1.0 sec are available at intervals of 0.1 sec.
- Alternatives to this have already been explained in the general part of the description.
- the device 1 shown is now characterized in that the process interval t p is determined by the control electronics 6 itself by evaluating the time interval occurring during the previous single or multiple individual triggering of a process step or the time intervals between the individual actuations of the actuating element 8.
- the control electronics 6 are therefore self-learning in this sense. From the triggering time intervals of previous actuations, the control electronics 6 determines the rhythm in which the operator doses specifically. This then specifies the process interval t p .
- the operator himself does not have to set a process interval t p on the programming element 9, rather the process interval t p automatically follows the operating rhythm of the operator.
- a first possibility for determining the process interval t p now consists in the control electronics 6 adopting the triggering interval of the last individual metering as the process interval t p before the sustained actuation of the actuating element 8 begins.
- FIG. 4 shows a flow chart which shows a further preferred embodiment of the device 1 according to the invention. It is provided here that the control electronics 6 adopt a mean value of the last n (n> 1), here the last two triggering time intervals before the actuation element 8 continues to be actuated, as the process interval t p . In extreme cases, n can simply include all of the individual doses that have previously expired.
- FIG. 4 shows individual doses 1, 2, 3, 4, 5, the automatic dosing beginning with step 6 and then continuing via steps 7, 8, 9.
- the last two triggering time intervals are recorded, here t p3 and t p4 before the actuation element 8 continues to be actuated in the metering step 5. This is shown by the dashed line.
- the time intervals of the last n individual doses can also be weighted. This can be done, for example, in such a way that the last three individual doses are recorded, but when averaging, the time interval between the last and the penultimate individual dosing is weighted twice. In this consideration, it is also assumed that the process interval t P results directly from the trigger interval, so that a conversion or correction is not necessary.
- the graphical representation in FIG. 4 could suggest that only the remaining interval is meant here in each case. Of course, this is not the case; the graphic representation is intended to describe the process interval t P , that is to say the time interval between the start of a process step and the start of the following process step.
- a possibility of evaluating the individual doses using the control electronics 6 also consists in that an average of one of the control electronics 6 Most individual doses before automatic dosing starts a statistical evaluation method is determined. Such a statistical Evaluation methods can also be groups of individual dosages spaced apart from one another with a longer learning phase.
- One way of A filter is implemented in the statistical analysis, for example Control electronics 6, the atypically large and / or atypically small time intervals eliminated.
- the control electronics 6 of the dispensing device 1 can also be designed such that a process interval t p previously determined or taken over by the actuation of the actuating element 8 is stored in the control electronics 6 until a possible active deletion and / or until the dispensing device 1 is switched off and at repeated continued actuation of the actuating element 8 is effective again.
- the process interval t p once determined, is thus retained even when the metering activity is interrupted, so that the operator can continue to maintain the rhythm once found.
- An active deletion of the stored process interval t p should also take place by pressing a programming button 11 of the programming element 9 and / or by repeated multiple individual dosing.
- the control electronics 6 is signaled by the operator that the operator wishes a new determination of the process interval t p .
- the operator may also have changed, the new operator would like to find his own rhythm and have it taken into account in the process interval t p .
- This configuration of the control electronics 6 serves this purpose.
- the process interval t p can be corrected in the sense explained above, for example by means of a preferably permanently set correction factor.
- the choice of the correction factor and the accuracy of the determination of the process interval t p as a whole is of course generally determined by the setting accuracy for the process interval t p . If only setting steps of 0.1 sec are possible anyway, you can work with a larger error here than if you have a smaller division for the setting steps of the process interval t p in the control electronics.
- a change in the operating rhythm of the operator after the sustained actuation of the actuating element 8 begins can also be taken into account in that the control electronics, even when the actuating element 8 is continuously actuated, detects the cycle of the movement of the dispensing device 1 and uses it to correct the process interval t p .
- the control electronics since the actuation of the actuating element 8 itself can no longer be used as a control variable for the control electronics 6, the movement of the dispensing device 1 by the operator from the receptacle 12 to the receptacle 12 must be detected in some other way. This can be done, for example, by means of an acceleration sensor, which detects the sideways movement of the dispensing device 1 by evaluating the lateral acceleration, and whose signal is evaluated accordingly by the control electronics 6.
- the actuating element 8 as non-mechanical, particularly pure perform electronic, preferably non-contact element.
- an optoelectronic actuating element 8, as in the 1 shown with light transmitter 8 'and light receiver 8 " one covered by a deformable or movable cover 8 "' Transmission path is evaluation technology, especially with regard to Evaluation software, particularly useful.
- the device 1 creates with the self-learning Control electronics 6 an easy-to-use system with which extensive Working with a hand-operated device 1 comfortable and can be carried out individually and consciously and therefore extremely quickly.
