DETAILED DESCRIPTION

[0023] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as limiting the utility model.

[0024] Embodiment one

[0025] Combined with appendix Figure 1 A biopharmaceutical filling device includes a storage tank 1. A cylinder 2 penetrating the bottom of the storage tank 1 is provided. A movable thick-walled tube 3 is sealed inside one end of the cylinder 2 located outside the storage tank 1. A screw cylinder 4, which adjusts the liquid storage volume of the cylinder 2 and abuts against the thick-walled tube 3, is threadedly connected to one end of the cylinder 2 located outside the storage tank 1. An overflow port 5 is provided at the top of one end of the cylinder 2 located inside the storage tank 1. A piston 6 is provided at one end of the cylinder 2 located inside the storage tank 1. A connecting rod 7 extending to the outside of the storage tank 1 is provided on the piston 6. A buffer device 8 and a telescopic rod 9 are sequentially provided on the connecting rod 7. A liquid pump 10 with its input end connected to the storage tank 1 and its output end connected to the cylinder 2 is provided on the outside of the storage tank 1.

[0026] Rotate the screw 4 to adjust its position on the cylinder 2, thereby adjusting the position of the thick-walled tube 3 inside the cylinder, and thus adjusting the liquid storage volume of the cylinder 2. The liquid pump 10 continuously injects the liquid from the storage tank 1 into the cylinder 2. After the cylinder 2 is full, control the extension rod 9 to extend. The extension rod 9 drives the buffer device 8, connecting rod 7, and piston 6 to move. The piston 6 moves inside the cylinder 2 to discharge the excess liquid from the overflow port. The piston continues to move downward to discharge the liquid in the cylinder 2 through the thick-walled tube 3.

[0027] The outer wall of the cylinder 2 located outside the liquid storage tank 1 has a groove 11 arranged along the length of the cylinder 2. The groove 11 has a scale line 12, through which the amount of medicine liquid that can be stored in the cylinder 2 can be determined.

[0028] The top of the liquid storage tank 1 is provided with a U-shaped part 13, and the telescopic rod 9 is provided on the U-shaped part 13.

[0029] Example 2

[0030] The buffer device 8 includes a cylinder 14 connected to a telescopic rod 9 at one end, and the other end of the cylinder 14 is sleeved on a connecting rod 7. The cylinder 14 is provided with an elongated through hole 15 along the length of the cylinder 14. A spring 16 is provided inside the cylinder 14, with one end abutting against the telescopic rod 9 and the other end abutting against the connecting rod 7. The end of the connecting rod 7 is provided with a protrusion 17 extending into the elongated through hole 15.

[0031] When piston 6 contacts thick-walled tube 3, connecting rod 7 stops moving under force, spring 16 contracts, and cylinder 14 moves downward to fit onto connecting rod 7, thus providing a buffering effect.

[0032] The bottom of the thick-walled tube 3 is connected to a filling tube 18, which can be inserted into the container to facilitate filling of the medicine.

[0033] The telescopic rod 9 and liquid pump 10 mentioned in this utility model, as well as their matching power supply and controller, can be provided by the manufacturer. Apart from that, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
