Referring to fig. 1 and 2, a dispensing apparatus for dispensing a sample in a sample cup 52 is provided according to an embodiment of the present invention. This partial shipment equipment includes: a weighing mechanism 50, a suction mechanism 10, an adding mechanism 20 and a blending mechanism 30.

The weighing mechanism 50 has a weighing position for placing the sample cup 52 and the weighing mechanism 50 is for weighing the sample in the sample cup 52. Optionally, the weighing mechanism 50 is an electronic balance, and in practical use, the weight of the sample cup 52 is pre-zeroed, so that the weight of the sample in the sample cup can be directly obtained by only placing the sample cup 52 with the sample on a weighing platform of the electronic balance.

The kneading mechanism 30 has a plurality of kneading positions for placing the vial 32. The method for placing the freezing tube 32 on the blending position can be manual placement or mechanical arm grasping, and is not limited herein. In actual use, the number of the required freezing tubes 32 is calculated according to the weight of the sample, and the freezing tubes 32 with the corresponding number are placed on the freezing positions manually or mechanically. It should be understood that, in other embodiments, a sufficient number of the freezing tubes 32 may be directly placed on the mixing mechanism 30 without calculating the number of the freezing tubes 32, so as to ensure that the sample can be completely transferred into the freezing tubes 32, which is not limited herein.

The adding mechanism 20 is in communication with the weighing mechanism 50 and adds the additive to a corresponding number of the cryopreservation tubes 32 according to the weight of the sample weighed by the weighing mechanism 50. Specifically, the adding mechanism 20 calculates the number of the freezing tubes 32 required based on the weight of the sample, and adds the additive to the number of the freezing tubes 32.

And the suction mechanism 10 is in communication connection with the adding mechanism 20 and is controlled to move to a material taking position for sucking the sample in the sample cup 52 and a material discharging position for releasing the sample to the freezing tube 32 added with the additive. When the adding mechanism 20 adds the additive to a certain cryopreservation tube 32, the position of the cryopreservation tube 32 is sent to the suction mechanism. The suction mechanism 10 moves to the material taking position, extracts the sample from the sample cup 52, moves to the discharging position of the freezing tube 32 corresponding to the position according to the position sent by the adding mechanism, and releases the extracted sample into the freezing tube 32.

In actual use, the sample cup 52 containing the sample is first placed on the weighing position of the weighing mechanism 50 to obtain the weight of the sample. According to the weight of the sample, a sufficient number of freezing tubes 32 are manually or mechanically arranged on the blending mechanism 30, so that the sample in the sample cup can be completely filled into the freezing tubes 32. Then, the adding mechanism 20 calculates the number of the freezing tubes 32 to which the additive needs to be added, based on the weight of the sample, and adds the additive to the corresponding number of the freezing tubes 32. The aspiration mechanism 10 is then moved to a dispensing position above the sample cup 52 to draw the sample from the dispensing cup. The pumping mechanism 10 is then moved over one of the vials 32 to which the additive has been added, releasing the sample into the vial 32. This is repeated until all of the additive-loaded cryopreservation tubes 32 have been loaded with sample by the aspiration mechanism 10. Finally, all the samples in the freezing tube 32 are fully mixed with the additives by the mixing mechanism 30.

Above-mentioned partial shipment mechanism matches the cryopreserved pipe 32 that corresponds quantity through weighing mechanism 50 to through suction mechanism 10 and add mechanism 20, replace the manual work to carry out the partial shipment to the sample in the partial shipment cup, make the partial shipment process more accurate and more simple and convenient.

It should be understood that the sample may be other liquids to be dispensed, and the additive may be other drugs, which is not limited herein. The blending mechanism 30 can be a conventional blending device, and therefore, will not be described herein.

In the embodiment of the invention, as the sample has multiple types, such as different blood types corresponding to different sperms, in order to better distinguish the types of the sample, the sample cup 52 is provided with the first identification mark, and the types of the sample can be visually recorded through the first identification mark on the sample cup 52. Further, in order to avoid that the types of the samples in the cryopreservation tubes 32 cannot be determined after the split charging, the split charging equipment further comprises a recognition mechanism 40 and a marking mechanism which are in communication connection with each other, wherein the recognition mechanism 40 is used for recognizing the first recognition mark and controlling the marking mechanism to mark the cryopreservation tubes 32 added with the samples.

In the actual use process, after the recognition mechanism 40 recognizes the first identifier, the marking mechanism is controlled to mark the cryopreservation tube 32 with the added sample according to the first identifier, so that a user can visually know the type of the sample in the cryopreservation tube 32 through the identifier. It should be noted that the first mark may be a conventional mark such as a color, a bar code, etc., the identification mechanism 40 may be a commonly used identification device such as a camera, a bar code, etc., and the marking mechanism may be a commonly used marking device such as a coloring device, a bar code pasting device, etc., which is not limited herein.

In practice, after the recognition mechanism recognizes the first mark, the recognition result is transmitted to the screw cap assembly 41. After the sample and the additive are added into the cryopreservation tube 32, the cap screwing assembly 41 selects the bottle cap 34 with the corresponding second identification mark according to the identification result, and locks the bottle cap 34 on the cryopreservation tube 32. Thus, the sealing step and the marking step of the cryopreservation tube 32 are integrated into one step, so that the steps are simplified, and the mark on the cryopreservation tube 32 is more visual.

In practical use, when the adding mechanism 20 adds an additive into a certain cryopreservation tube 32, the position information of the certain cryopreservation tube 32 is transmitted to the first transfer assembly, and the first transfer assembly controls the first suction head 11 to move to the material taking position, so that a certain amount of sample is extracted from the sample cup 52 through the first suction tube 12. The first suction assembly carries the sample to move to the emptying position above the corresponding freezing tube 32 according to the position information through the first transfer assembly, and the sample is released into the freezing tube 32. This is repeated until all of the additive-containing vials 32 have been filled with the sample. Further, after the sample in the sample cup is subpackaged, the first suction pipe 12 on the first suction head 11 can be replaced, and the sample for subsequent subpackage is prevented from being polluted.

It should be noted that the amount of the sample sucked into the sample cup 52 by the first sucking component each time may be a fixed amount, or the sucking force of the first sucking head may be changed according to the mixture ratio of different samples and additives to achieve different sucking amounts, which is not limited herein.

In some embodiments, the first suction head 32 is moved by the first transfer assembly, and further includes a first discard position and a first installation position, wherein when the first suction head 32 is in the first discard position, the first suction head 11 is separated from the first suction conduit 12 to discard the used first suction conduit 12, and when the suction mechanism 10 is in the first installation position, the first suction head 11 is connected to the first suction conduit 12 in the first installation position to install the unused first suction conduit 12.

The second transfer assembly is controlled to move the second tip 21 back and forth between the additive source 25 and the cryopreservation tube 32. When the second suction head 21 is located at the additive source 25, the second suction head 21 sucks the additive in the additive source through the second suction pipe 22. When the second pipette tip 21 is moved to the mixing mechanism 30, the second pipette tip adds the sucked additive to the corresponding cryopreservation tube 32.

In the actual use process, after the adding mechanism 20 obtains the weight of the sample, the number of the required freezing tubes 32 is calculated according to the ratio of the sample to the additive. The second transfer assembly controls the second suction head 21 to move above the additive source 25, and the second suction head 21 sucks a metered amount of additive through the second suction pipe 22. The first pumping assembly carries the additive to move over one of the cryopreservation tubes 32 by the second transfer assembly, adding the additive to the cryopreservation tube. This is repeated until the number of vials 32 to which the additive has been added meets the desired number of vials 32. Further, after the additive is added, the user can replace the second suction tube 22 of the second suction head 21, so as to avoid affecting the subsequent split charging of the sample.

It should be noted that the amount of the additive in the additive source sucked by the second suction assembly at a time may be a fixed amount, or the suction force of the second suction head 21 may be changed according to the mixture ratio of different samples and additives to achieve different sucked amounts, which is not limited herein.

It is understood that the positioning member 51 may be a clamping member, a robot, or other conventional fixing device.

In some embodiments, the positioning member 51 is communicatively connected to the weighing mechanism 50, and when the weighing mechanism 50 detects that the weight of the sample is greater than or equal to a threshold value, the weighing mechanism 50 controls the positioning member 51 to contact the sample cup 52, so as to fix the sample cup 52. When the weighing mechanism 50 detects that the weight of the sample is below the threshold value, the weighing mechanism 50 controls the positioning member 51 to separate the positioning member 51 from the sample cup 52.
