[0022] In the prior art, the pipette does not have a feedback signal when the operator operates the pipette to dispense liquid, which cannot determine the accuracy of the dispensing at this time, which may lead to experimental failure. Moreover, when the operator operates the pipette to dispense liquid, the pipette cannot remind the operator that the pipette is in an inclined state, which may lead to experimental failure. At the same time, when the operator holds the pipette to dispense liquid, the pipette does not have a function of transmitting data to the background through a wireless way after being inclined and saving the data when the pipette dispenses liquid, which cannot let the operator analyze the data when the pipette dispenses liquid and cannot more effectively improve the experimental efficiency.
[0023] To solve the above technical problems and improve the accuracy of pipetting, as shown in Figure 1 In the present embodiment, the pipetting device comprises a pipette body 10, a sensor 20, an alarm and a controller. The sensor 20 is arranged on the pipette body 10, and the sensor 20 can detect the position of the pipette body 10. The alarm is arranged on the pipette body 10. The controller is arranged on the pipette body 10, and the controller is in communication connection with the sensor 20 and the alarm.
[0024] The technical scheme of the embodiment is applied, the sensor 20, the alarm and the controller are all arranged on the pipettor body 10. The sensor 20 can detect the position of the pipettor body 10, and the controller is connected with the sensor 20 and the alarm. Through the above arrangement, when the pipetting device is used by the experimenter, the sensor 20 can detect the position of the pipettor body 10 in real time and transmit a signal to the controller, and the controller can control the alarm according to the signal, thereby reminding the experimenter, so as to ensure the position accuracy of the pipetting device when it is used. Therefore, the technical scheme of the embodiment effectively solves the problem that it is difficult to ensure the accuracy and consistency of operation when the pipettor is operated in the related art.
[0025] The controller is connected with the sensor 20, and the controller is used for receiving and processing the data transmitted by the sensor 20. The controller compares the received data with a pre-set displacement threshold value, and if the displacement of the pipetting device exceeds the set threshold value, the controller triggers the alarm.
[0026] Specifically, the sensor 20 and the alarm of the pipetting device of the embodiment can alarm the misoperation of the pipetting process, remind the experimenter of the operation error, correct the incorrect pipetting posture of the experimenter, improve the accuracy of pipetting, and improve the experimental efficiency.
[0027] As shown in Figure 1 In the embodiment, the sensor 20 is located on the axis of the pipettor body 10. The above arrangement can more accurately determine the position of the pipettor body 10, so that the sensor 20 can accurately detect the position of the pipettor body 10.
[0028] As shown in Figure 1 In the embodiment, the sensor 20 includes an acceleration sensor or an angle sensor. The above arrangement can ensure the accuracy of detection.
[0029] It should be noted that the acceleration sensor is a sensor capable of measuring acceleration, and specifically includes a mass block, a damper, an elastic element, a sensitive element and an adaptive circuit.
[0030] The angle sensor is a gyroscope.
[0031] As shown in Figure 1 In the embodiment, the pipetting device further includes a display screen 30, and the display screen 30 is arranged on the pipettor body 10. The arrangement of the display screen 30 can facilitate the observation of the experimenter, so that the experimenter can more easily observe.
[0032] As shown in Figure 1As shown, in this embodiment, the sensor 20, controller, and display screen 30 are all located at the first end of the pipette body 10. This arrangement makes the overall operation of the pipetting device more efficient. Specifically, the placement of the sensor 20, controller, and display screen 30 avoids occupying pipetting space.
[0033] like Figure 1 As shown, in this embodiment, the display screen 30 is tilted. The tilted design of the display screen 30 makes it easier for the user to observe, thus making operation more convenient. The controller can process the data collected by the sensor 20 and display it on the display screen 30.
[0034] like Figure 1 As shown, in this embodiment, the angle between the display screen 30 and the horizontal plane is between 15° and 60°. This angle setting facilitates user observation. Specifically, in this embodiment, the angle between the display screen 30 and the horizontal plane is 30°. Of course, in other embodiments, the angle between the display screen 30 and the horizontal plane can also be 20°, 40°, 45°, 50°, or other angles.
[0035] like Figure 1 As shown, in this embodiment, the pipetting device also includes a pipette tip 40, which is detachably disposed at the second end of the pipette body 10. This design ensures accurate pipetting and guarantees precise liquid volume in the experiment. It also prevents cross-contamination between different samples. Furthermore, the detachable pipette tip 40 improves operational efficiency.
[0036] like Figure 1 As shown, in this embodiment, the pipette body 10 includes a pipette body 11 and a gas filter 12. The gas filter 12 is disposed inside the pipette body 11 and located at the end of the pipette body 11 away from the controller. The gas filter 12 can prevent the generation of air bubbles. Specifically, when drawing liquid, the gas filter 12 can reduce the amount of air entering the interior of the pipette body 10, thereby reducing the generation of air bubbles and ensuring the accuracy of the liquid.
[0037] like Figure 1 As shown, in this embodiment, the alarm includes a light alarm, a vibration alarm, or a sound alarm. These alarms can quickly alert the experimenter, allowing for timely correction of the pipetting device's position.
[0038] The pipetting device of the embodiment can be used to manage and monitor the pipetting of the handheld pipetting device of the experimental personnel in the laboratory, remind the experimental personnel to correct the pipetting posture when the displacement of the pipetting device is not standardized, and the internal controller of the pipetting device can transmit data to the background for the analysis of the test personnel. At the same time, when the mechanical arm holds the pipetting device, the orientation monitoring and mutual sensing adjustment with the mechanical arm can be carried out to ensure the correct orientation of the pipetting device. An acceleration sensor is integrated in the pipetting device, which can sense the displacement of the pipetting device in real time and issue an alarm when the displacement exceeds the set range.
[0039] The pipetting device of the embodiment has the following advantages:
[0040] 1. Ensure the accuracy of pipetting: pipetting is a common operation step in experiments and is an important link to ensure the accuracy of experimental results. Long-term experimental operation can cause the experimental personnel to be tired, which can easily cause the pipetting device to be operated non-standardly, resulting in an inclination angle in the pipetting process. The pipetting device with an alarm system (sensor 20, controller and alarm) exceeding the threshold displacement can alarm the non-standard use of the pipetting device by the operator, ensure that the operator performs the pipetting operation at the correct displacement, and thus improve the accuracy and reliability of pipetting.
[0041] 2. Improve experimental efficiency: time is a very valuable resource in laboratory work. The handheld pipetting device can improve experimental efficiency and reduce unnecessary time waste through intelligent functions such as automatic recording of experimental data and automatic calculation of experimental results.
[0042] In the embodiment, the automatic pipetting mechanism includes a mechanical arm, a central control module and a pipetting device, wherein the pipetting device is the pipetting device described above. The pipetting device described above can realize alarm reminding, so that the accuracy of the position of the pipetting device when in use is better.
[0043] The pipetting device is arranged on the mechanical arm, and the central control module can monitor the angle and position of the pipetting device. Through the above arrangement, intelligent pipetting can be effectively realized, that is, when the mechanical arm holds the pipetting device for pipetting, the real-time monitoring of the angle and orientation of the pipetting device can be realized, and the real-time inclination angle and orientation of the pipetting device are sensed by the mechanical arm to ensure that the pipetting device has the correct pipetting angle and orientation during the pipetting process of the mechanical arm.
[0044] In the description of the utility model, it is understood that the orientation words such as '' front, back, up, down, left, right '' '' horizontal, vertical, perpendicular, horizontal '' and '' top, bottom '' and the like indicated orientation or positional relationship is usually based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply that the device or element indicated must have a particular orientation or be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the protection scope of the utility model;The orientation words '' inside, outside '' refer to the inside and outside relative to the contour of each component.
[0045] For the convenience of description, spatial relative terms such as '' above'', '' above'', '' upper surface'', '' upper '' and the like can be used here to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawing. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawing. For example, if the device in the drawing is inverted, the device described as '' above '' or '' above '' other devices or structures will be positioned '' below '' or '' below '' other devices or structures. Thus, the exemplary term '' above '' can include both '' above '' and '' below '' orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative description used here is interpreted accordingly.
[0046] In addition, it should be noted that the use of '' first'', '' second '' and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore can not be understood as the limitation of the protection scope of the utility model.
[0047] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model, for those skilled in the art, the utility model can have various changes and changes.
