Description

Technical Field

[0001] The utility model belongs to the technical field of liquid medicine filling, in particular to an automatic filling device for injection liquid. Background Art

[0002] Injection refers to a sterile solution made of medicine for injection into the body, as well as a sterile powder or concentrated solution for preparation into a solution or suspension before clinical use. Due to the characteristics of rapid efficacy, strong practicality and storage resistance, injection is widely used in the medical field. After the production or preparation of injection, it is necessary to operate the injection filling equipment to fill the injection into medicine bottles for easy carrying and use. The main components of the injection filling equipment include a base, a support frame, a medicine tank and a discharge pipe.

[0003] After searching, a patent document with patent announcement number CN219297139U discloses a feed-controllable injection filling device, which relates to the injection filling technology field, and includes a base, a support frame is fixedly connected to the edge of the upper surface of the base, a support plate is fixedly connected to the top of the support frame, a circular array of support columns is provided on the top of the support plate, a closed ring is fixedly connected to the top of the support column, a vertical hole is provided on the top of the closed ring, a horizontal hole is provided on the inner ring wall of the closed ring on one side of the vertical hole, and the top of the vertical hole is fixedly connected to the bottom of the liquid storage bucket. It is only provided with a stepper motor at the bottom of the liquid collection plate for filling, and the liquid collection plate is driven by a single stepper motor to take liquid from the liquid storage bucket and unload from the drop hole, thereby realizing quantitative filling of the injection into the storage bottle. The entire filling device has a simple structure and relies on few electrical components, and the subsequent maintenance of the entire device is simple, without the participation of professionals, reducing maintenance costs.

[0004] However, it still has the following disadvantages in actual use:

[0005] In the existing injection filling equipment, during use, the stepper motor is started to drive the liquid collection plate to rotate, thereby adjusting the position between the horizontal hole and the docking hole. When the horizontal hole and the docking hole are aligned, the injection in the liquid collection cavity can be filled. However, during the rotation of the liquid collection plate, the sealing effect between the closed ring and the liquid collection plate cannot be guaranteed, which will cause the injection liquid in the liquid collection cavity to leak out, thereby increasing the waste of injection liquid.

[0006] 2. During use, the existing injection filling equipment introduces the injection into the interior of the medicine bottle through the provided injection tube, but the distance between the support frame and the support plate is fixed, and the distance between the injection tube and the support frame cannot be adjusted, which makes it inconvenient to introduce the injection liquid into the interior of medicine bottles of different sizes, thereby reducing the scope of application of the existing injection filling equipment and reducing its practicality.

[0007] To this end, we provide an automatic injection filling device to solve the above problems. Utility Model Content

[0008] The utility model aims to provide an automatic injection filling device, which solves the problems of poor storage sealing of the existing injection filling device during use and inconvenience in filling the injection into medicine bottles of different sizes by arranging a filling component and a lifting component.
