Centrifugal quantitative point pick and place device

The invention relates to a medicine sampling device, in particular to a centrifugal quantitative point medicine pick-and-place device.

In the field of scientific research, all results are tested through a large number of different conditions, and after repeated verifications, the credibility can be confirmed. Taking the biochemical and pharmacological drug development methods as an example, in order to find the ideal compound type and dosage suitable for the drug, it is necessary to first test the drug type for the lesion, and find the most suitable compound for the lesion, and then perform the compound drug. Volume controlled experiment. Because the drug is used to solve the human body's lesions, if the dose is insufficient, it may not solve the disease. However, if the drug is too heavy, it will cause harm to the human body. Therefore, it can be seen that the control of the drug volume is important in the process of drug development.

In the past drug development process, the dropper was used for the handling of the drug, such as the "Pipette tip" of US Pat. No. 20,100,316,542, which discloses a dropper head comprising a connection to a dispensing device. An attachment section and a liquid containing section, the medicine storage section including a first area connected to the connecting section and a second area connected to the first area, wherein the first area is further The utility model comprises a tip portion, an intermediate portion and a stepped portion, and when the medicine is taken, the pipette head is first connected to the dispensing device, and the dispensing device is used for dispensing The device controls the dose to be taken, continuously contacts the tip end of the pipette tip with the drug to be sampled, and sucks the drug to the middle portion for storage, and when the drug is placed, the drug is taken Put the dropper head of the drug into the test In the tube, the compressed gas is supplied from a gas pressure member of the dispensing device to extrude the drug from the tip portion in a required amount, so that the medicine falls into the test tube to complete the placement of the medicine.

Since the dispensing device is controlled by mechanical or electronic means, it is easy to produce errors after long-term use, and thus must be corrected or repaired; however, even a very small amount of drug error will still result in the final experiment. This has a considerable effect, and these errors are usually not observed by the naked eye, so when the dispensing device produces an error, it will have a great adverse effect on the accuracy of the experiment.

Furthermore, after the medicine is aspirated, the medicine is first stored in the middle portion, and then released according to the user's needs, so that the amount released by the medicine is also caused by human factors, and is taken out and stored. If the drug in the middle portion is not used up, it cannot be recycled to avoid contamination of the drug, thereby causing waste of the drug. In addition, if different medicines are to be taken and placed, the dripper head must be cleaned while the medicine is being taken and discharged. However, the conventional dropper head structure is not suitable for cleaning, and the medicine is easily left in the dropper head. , which in turn causes mutual contamination between different drugs and seriously affects the results of subsequent tests.

The main purpose of the invention is to improve the quantitative accuracy of the medicine during pick and place.

In order to achieve the above object, the present invention provides a centrifugal quantitative drug dispensing device for quantitatively taking and dispensing a drug body, the centrifugal quantitative drug dispensing device comprising a drug containing tank, a connecting member and a rotary drive And the at least one medicine opening, the medicine tank comprises a receiving space for carrying the medicine body and a circulation opening, the connecting piece is connected to the medicine tank and comprises at least one connecting the medicine tank and adjacent to the circulation a positioning rib on one side of the opening and a rotating shaft body connected to the end of the at least one positioning rib away from the receiving groove, the rotary driving member is connected to the rotating shaft The rotating shaft body is away from one side of the at least one positioning rib, and the at least one medicine opening is formed between the rotating shaft body and the medicine receiving groove and opposite to the at least one positioning rib.

When the medicine is to be taken, the centrifugal quantitative dispensing device is first placed in a container containing the medicine body, and the surface of the medicine body in the container is higher than the medicine tank. The medicine tank is removed from the container, so that the medicine body is carried in the accommodating space of the medicine accommodating tank; and when the medicine is to be discharged, the centrifugal medicine dispensing device is first placed in a test tube to be discharged The rotary drive member is used to drive the rotating shaft body connected thereto to rotate, thereby driving the resin tank to rotate, so that the medicine body in the accommodating space is pulled out from the medicine discharge opening due to the centrifugal force generated by the rotation. The accommodating space is dropped into the test tube, thereby completing the drug delivery.

As can be seen from the above description, the present invention has the following features:

1. The loading space of the drug solution tank is used to carry the drug body, so that the dose of each medicine is fixed, and the effect of accurate taking can be achieved.

2. The rotation driving member drives the resin container to rotate through the connecting member, so that the medicine body can be thrown out of the medicine tank by the centrifugal force generated by the rotation.

3. The simple structure of the centrifugal quantitative drug pick-and-place device makes it easy to clean and makes the drug body not easy to remain, thereby avoiding the problem of mutual contamination of drugs caused by the residue of the drug body.
