Definitions
- the invention relates to a metering device.
- Dosing devices are used in the laboratory for dosing liquids. In general, they have a displacement device with a Displacement organ, by the displacement of a liquid or a Air column is moved. They are particularly in the following statements known:
- the bubble principle dosing devices have a Piston-cylinder unit, by means of which an air column is displaceable to Aspirate liquid into a pipette tip and expel it.
- the piston-cylinder unit does not come in contact with the Liquid. Only the pipette tip, which is mostly made of plastic, will wetted and can be replaced after use.
- a syringe filled with sample liquid By contrast, in the case of metering devices operating as direct displacers a syringe filled with sample liquid. Piston and cylinder of the syringe are wetted by the liquid, so that the syringe before dosing another liquid usually replaced or cleaned by a new syringe becomes.
- the syringe is usually made of plastic.
- Pistonless metering devices have, for example, a pipette tip with a balloon-like end portion for sucking in liquid expanded and compressed for ejection.
- Such pipette tips have also been designed as a replacement part.
- Dispensers are dosing devices that take a recorded amount of one Can deliver liquid repetitive in small subsets.
- multichannel dosing devices that use multiple dosing devices include, to simultaneously several amounts of liquid too dosing.
- Air cushion, NOTES- and piston-less dosing devices can have a fixed or a variable metering volume.
- a Changing the dosing volume is usually by changing the displacement reaches the displacement device. For example, this can be done the displacement of the piston or the degree of deformation of the balloon-like Endabiteses changed or exchanged the displacement device become.
- the operator receives a tactile feedback. Any change to the Actuation required force is noticed immediately. So the operator Check that the dosing device works correctly. The speed The intake and delivery of the liquid can be done by the operator be varied directly and without delay. Also, a tax is the Liquid in a free jet possible. A contact between metering device and a vessel for the liquid can be avoided become. Furthermore, the metering device is independent of a power supply. It can be used intuitively by the user. An elaborate Instruction or programming is not required.
- US 5,389,341 discloses a motorized pipette with an actuator button, when the displacement of an actuating knob the movement controls a piston via an electronic control system.
- the Displacement of the actuating knob is via an electronic displacement sensor queried and the query result is electronically via a Stepper motor implemented in the drive movement of the displacement device.
- This electrical metering device has the disadvantages described above.
- the invention is based on the object, a metering device to provide the operator with a tactile feedback on the effective forces, a variation of the speed of recording and Discharge of the liquid during dosing, the release of the liquid in Free jet and easy use facilitates or allows and the Power requirement for operation compared to manual pipettes reduced.
- the metering device is a combination of a manual and from an electrical dosing device.
- the one from the operator force exerted on the actuator is wholly or partly the Displacement device supplied.
- the sensor detects the from Operator force and the controller controls the drive motor so, that the displacement device is supplied with an additional force, the supports the operator initiated force.
- the Dosing device with a fraction of a manual dosing device be applied to be applied force.
- electrical Dosing devices are the energy introduced by the operator not lost, but added to the drive power of the engine.
- the drive motor only supports the force for the actuation of the Displacement device.
- the positioning can be controlled by the operator and / or by the mechanics of the metering device, e.g. by a conventional limitation of the actuating travel by means of a stop. As a result, a particularly inexpensive electric drive is possible. Further advantages of the metering device are:
- the operator receives a tactile feedback. Any change for the Actuation required force is noticed immediately.
- the speed for receiving and dispensing the liquid can be direct and instantaneous be varied.
- the delivery of the liquid in a free jet is better than a traditional manual dosing device, because add the force of the operator and the power of the drive motor.
- the Dosing device can be used intuitively. An elaborate briefing or programming is not required. Is the electric Power supply not available (for example, when the battery is empty or Battery), can be further worked. It is only a higher force required.
- a motor and a battery or a battery can be designed smaller than in a conventional metering device since these elements do not replace the energy of the operator, but only complete.
- the actuating device is a manually axially sliding actuator button.
- the metering device is then operable like a conventional manual or electronic pipette or dispenser.
- the actuating device is opposite to Actuated force of a spring. This also corresponds to conventional pipettes or dispensers. The return movement of the actuator can then be controlled by the spring force.
- the actuating device is up to reaching a stop actuated. This will determine the exact positioning of the Displacement organ of the displacement device set. This also corresponds conventional manual pipettes or dispensers. A changeability the dosage. is also in a conventional manner by a adjustable stop achievable.
- the senor is in the Actuator integrated. It can be, for example, a plate-shaped, pressure-sensitive sensor acting in a Actuating knob is integrated perpendicular to the direction of actuation. According to In a further embodiment, the sensor is in an actuating surface of the Actuator integrated. According to another embodiment the sensor is a Force Sensing Resistor, abbreviated to: FSR.
- FSR Force Sensing Resistor
- the controller always controls the drive motor then constant when the sensor is manually on the actuator applied force detected.
- the drive motor can then, for example overcome a basic friction of the system in whole or in part, so that the operator only has the additional force for the displacement of the Apply displacer and, if appropriate, part of the system friction got to.
- the controller controls the drive motor in Dependence on the force detected by the sensor.
- the controller controls the drive motor in at least one Stage, where at several stages, the height of the drive power with the Sensor detected force increases.
- the controls Control the drive motor proportionally to that exerted on the sensor Force.
- the controller switches the drive motor when the sensor detects a large increase in force typical of the reaching of the stop is.
- the actuating device and the Drive motor via a coupling device with the displacement device connected.
- the coupling device may be a Act gear.
- the actuating device connected via a rod with the displacement device. This makes possible in particular in the case of a displacement device designed as a piston-cylinder unit a very simple construction.
- the electric drive motor with the rod coupled is e.g. with a pinion, that with a toothing on the rack meshes, executed.
- control knob is actuated until one with the Rod connected stop abuts against a fixed counter-stop.
- Embodiments relate to metering devices, the one displacement device with a piston in one Cylinder on Miniverdränger- and on air cushion dosing devices.
- a direct displacement metering device comprises the Displacement device a receiving volume for liquid with a Through opening to the environment and an air cushion dosing device is the displacement device with a receiving volume for Liquid connected to a passage opening to the environment.
- the actuating device is with a device for releasing and / or ejecting a pipette tip and / or Coupled syringe.
- the effort required for loosening and / or dropping a The pipette tip and / or syringe is also reduced by the invention.
- the metering device is a manual metering device.
- the power supply at least a battery and / or at least one battery.
- the metering device 1 has a cylindrical housing 2, from which - in the Drawing - above an axially operable actuator button 3 protrudes.
- the actuating knob 3 is connected via a rod 4 with a piston 5.
