Description

Technical Field

[0001] The utility model relates to the technical field related to veterinary drug production, in particular to a veterinary drug pre-filled syringe. Background Art

[0002] Veterinary drugs are drugs used for preventing, treating, diagnosing animal diseases or purposefully regulating the physiological functions of animals. After the liquid veterinary drugs are proportioned and mixed, the liquid veterinary drugs are often passed into a pre-filling device, and then the liquid veterinary drugs in the pre-filling device are filled into small bottles. In the existing pre-filling device for liquid veterinary drug production, during use, the liquid veterinary drugs are prone to precipitation, and the precipitated liquid veterinary drugs are likely to affect the structures for perfusion, resulting in problems such as blockage. At the same time, during perfusion, the filling amount of the liquid veterinary drugs should be accurately ensured, and different amounts of liquid medicine should be filled at one time according to the capacity of the actually used medicine bottles.

[0003] Therefore, we propose a pre-filling device for liquid veterinary drug production to solve the problems raised above. Summary of the Utility Model

[0007] Preferably, a soft seal is also fixedly arranged at the lower end of the perfusion tube, the soft seal is in the shape of a plastic sheet, and a cross-shaped closing gap is arranged on the soft seal.

[0008] Preferably, a cover is threadedly connected to the upper end of the transfer cylinder, and the cover is fixedly connected to the filter member through two metal thin rods.

[0009] Preferably, the cylinder body is made of a transparent material, and scale labels are arranged on the cylinder body.

[0010] Preferably, an electric telescopic rod is fixedly arranged on one side of the cylinder body, and the telescopic end of the electric telescopic rod is fixedly connected to the control rod through a connecting plate member.

[0011] Preferably, the inlet pipe is connected to the side wall of the transfer cylinder, and the connection position of the inlet pipe and the transfer cylinder is arranged above the filter element.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device is provided with a cylinder body cooperating with a piston. By driving the piston to move, liquid veterinary medicine can be extracted and extruded to form a perfusion operation. Moreover, a transfer cylinder is also provided. When the liquid veterinary medicine passes through the transfer cylinder, it will be filtered, avoiding the problem that the precipitated liquid veterinary medicine easily affects the structure for perfusion and preventing blockage and other problems. The filtering structure is simple and has good effect, and is convenient to handle. At the same time, when performing perfusion, the electric telescopic rod can be precisely controlled to accurately ensure the filling amount of the liquid veterinary medicine. According to the capacity of the medicine bottle actually used, different amounts of liquid medicine should be perfused at one time. The overall device is convenient to use.
