Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments and equipment, in particular to a packaging device for preparing cefotaxime sodium for injection. Background Art

[0002] Ceftriaxone sodium is a third-generation semi-synthetic cephalosporin, which is widely distributed in various tissues and body fluids throughout the body. Since Ceftriaxone sodium itself is in the form of crystalline solid particles, it is generally necessary to grind Ceftriaxone sodium when in use so that it can be quickly absorbed by patients. When in use, the existing Ceftriaxone sodium injection filling device generally crushes the Ceftriaxone sodium crystals and then screens them. Although a vibrator for cleaning is provided on the surface of the screen to prevent the incompletely crushed Ceftriaxone sodium from clogging the mesh, due to long-term use, the mesh of the screen will still be blocked by some incompletely crushed Ceftriaxone sodium particles, causing the mesh to slowly increase the number of clogging, thereby reducing the efficiency of the vibrator and the filling efficiency of the device.

[0003] After searching, for example (authorization announcement number CN219928020U) a packaging device for preparing sodium ceftriaxone for injection. It includes a fixed plate, the fixed plate is connected with two first support rods, the first support rods are connected together with an equipment box, the inside of the equipment box is connected with a first partition plate, the first partition plate separates the equipment box into a grinding chamber and a filter chamber, the grinding chamber is provided with an injection port, the grinding chamber is centrally symmetrically connected with a grinding motor, the grinding motors are connected with a grinding shaft, and the grinding shafts are connected with a grinding block.
