[0032] The present viscous material transfer method and device are used for viscous material transfer, such as a lanreotide gel syringe implant, in the production process of the lanreotide gel syringe implant, since the liquid medicine is very viscous and needs more than 1 MPa pressure to be pushed, the material needs to be transferred from a mixing tank (a first tank body 1) to a transfer tank body (a second tank body 2) for filling, and in the transfer process, the connecting section between the mixing tank and the transfer tank body needs to be first vacuumized to avoid the air in the pipeline affecting the filling during the transfer.

[0033] Embodiment one: A viscous material transfer method is carried out by using a viscous material transfer system as shown in the figure, the viscous material transfer system comprises a first tank body 1 and a second tank body 2 each having a piston 8 and used for boosting and pushing the material to move, and a vacuumizing cavity 3 which can be opened and closed, the first tank body 1 is provided with a discharge end 11, the second tank body 2 is provided with a feeding end 21, and the vacuumizing cavity 3 is provided with a locking mechanism 4; the viscous material transfer method comprises the following steps: Figures 2 to 10 S1, opening the vacuumizing cavity 3, and connecting the discharge end 11 and the feeding end 21 through the locking mechanism 4; S2, closing the vacuumizing cavity 3 to seal the connecting section of the discharge end 11 and the feeding end 21 in the vacuumizing cavity 3; S3, adjusting the connecting section of the discharge end 11 and the feeding end 21 by the locking mechanism 4 to form a gap for the air bubbles to pass through and prevent the material from passing through; S4, vacuumizing the vacuumizing cavity 3 for a set time length; S5, locking the discharge end 11 and the feeding end 21 by the locking mechanism 4 to seal and connect the connecting section of the discharge end 11 and the feeding end 21; S6, under the action of the pistons 8 of the first tank body 1 and the second tank body 2, the material in the first tank body 1 passes through the discharge end 11 and the feeding end 21 to enter the second tank body 2; S7, after the material in the second tank body 2 reaches a set amount, opening the vacuumizing cavity 3 and releasing the locking mechanism 4. The present viscous material transfer method uses the combination of the vacuumizing cavity 3 and the locking mechanism 4 to vacuumize the connecting section of the discharge end 11 and the feeding end 21, and in the vacuumizing process, the locking mechanism 4 makes the connecting section of the discharge end 11 and the feeding end 21 form a gap for the air bubbles to pass through and prevent the material from passing through, so that the material can be prevented from being sucked out in the vacuumizing process, the material waste is reduced, and the production cost is lowered. And by connecting the discharge end 11 and the feeding end 21 in the vacuumizing cavity 3 through the locking mechanism 4 and adjusting the tightness of the connecting section of the discharge end 11 and the feeding end 21, compared with connecting the discharge end 11 and the feeding end 21 through a connecting pipe, the material is not easy to be contaminated.

[0034]

[0035] ​The gap formed at the joint of the discharge end 11 and the feeding end 21 in S3, because the transferred material is viscous material, the viscous material is particularly viscous, even if the gap is large, only by the negative pressure environment of the vacuum cavity 3, without the pushing of the piston 8 of the first tank 1, the viscous material basically does not move along the discharge end 11, therefore, when the joint of the discharge end 11 and the feeding end 21 is vacuumized, the viscous material also cannot reach the position of the gap, so the gap formed at the joint of the discharge end 11 and the feeding end 21 is for the passage of bubbles and not for the passage of material. And the gap can be adjusted to be appropriate small, even if the viscous material passes through the gap, it also cannot pass through from the gap.

[0036] Embodiment two: Figures 2 to 10 An embodiment of the viscous material transfer system of the present application is shown, the viscous material transfer system of the embodiment includes the first tank 1 and the second tank 2 which both have the piston 8 and are used for pressurizing and pushing the material to move, and the openable and closable vacuum cavity 3, the discharge port of the first tank 1 is provided with the discharge end 11, the feeding port of the second tank 2 is provided with the feeding end 21, the vacuum cavity 3 is provided with the locking mechanism 4 inside, the locking mechanism 4 is used for detachably connecting the discharge end 11 and the feeding end 21 and adjusting the tightness of the joint of the discharge end 11 and the feeding end 21, and one side of the vacuum cavity 3 is provided with the vacuum port 7.

[0037] The transfer process of the viscous material transfer system: the first step, open the vacuum cavity 3, connect the discharge end 11 and the feeding end 21 through the locking mechanism 4; the second step, close the vacuum cavity 3, seal the joint of the discharge end 11 and the feeding end 21 in the vacuum cavity 3; the third step, adjust the gap formed at the joint of the discharge end 11 and the feeding end 21 for the passage of bubbles and the prevention of the passage of material through the locking mechanism 4; the fourth step, vacuumize the vacuum cavity 3 for a set time; the fifth step, lock the discharge end 11 and the feeding end 21 through the locking mechanism 4, seal and connect the joint of the discharge end 11 and the feeding end 21; the sixth step, under the action of the piston 8 of the first tank 1 and the second tank 2, make the material in the first tank 1 pass through the discharge end 11 and the feeding end 21 and enter the second tank 2; the seventh step, after the material in the second tank 2 reaches a set amount, open the vacuum cavity 3 and release the locking mechanism 4.

[0038] The gap formed at the joint of the discharge end 11 and the feeding end 21 in the third step will not allow the viscous material to pass through, because the viscous material is very viscous, and even if the gap is large, the viscous material will not move along the discharge end 11 without the pushing of the piston 8 of the first tank 1 in the negative pressure environment of the vacuum cavity 3. Therefore, the viscous material cannot reach the position of the gap when the joint of the discharge end 11 and the feeding end 21 is vacuumized. Thus, the gap formed at the joint of the discharge end 11 and the feeding end 21 will only allow the bubbles to pass through, and the viscous material will not pass through. Moreover, the gap can be adjusted to be small enough so that even if the viscous material passes through the gap, it cannot pass through the gap.

[0039] The viscous material transferring system can vacuumize the joint of the discharge end 11 and the feeding end 21 by combining the vacuum cavity 3 and the locking mechanism 4, and during the vacuumizing process, the locking mechanism 4 forms a gap at the joint of the discharge end 11 and the feeding end 21 to allow the bubbles to pass through and prevent the viscous material from passing through. Thus, the viscous material can be prevented from being sucked out during the vacuumizing process, and the waste of the viscous material is reduced, and the production cost is lowered. Moreover, by connecting the discharge end 11 and the feeding end 21 through the locking mechanism 4 in the vacuum cavity 3 and adjusting the tightness of the joint of the discharge end 11 and the feeding end 21, the viscous material is less likely to be contaminated compared with connecting the discharge end 11 and the feeding end 21 through a connecting pipe.
