Description

Technical Field

[0001] The utility model relates to the technical field of eye drop sterilization equipment, and more specifically, to an eye drop online sterilization device. Background Art

[0002] Eye drops are liquid medications used for ocular treatment, to relieve eye discomfort, treat eye diseases, or prevent infection. Levofloxacin eye drops are a commonly used antibacterial drug used to treat eye diseases caused by bacterial infections. Eye drops come into direct contact with the eyeball, and any microbial contamination can cause serious eye infections. Therefore, eye drops must undergo strict sterilization during production. During production, the base water for eye drops must be sterilized.

[0003] The existing publication, CN213284498U, is titled "An Online Sterilization Device for an Eye Drop Production Line." The device comprises a housing, a barrel fixedly mounted on its inner wall, a feed tube fixedly mounted on its surface, a rotating shaft rotatably mounted on its inner wall, a stirring rod fixedly mounted equidistantly on the surface of the rotating shaft, a motor fixedly mounted on its surface, heating rings slidably mounted on its inner wall, and a connecting rod fixedly mounted between the heating rings. The housing surface is symmetrically provided with through grooves, a filter cartridge fixedly mounted on its surface, a sealing ring fixedly mounted on its inner wall, and a filter element slidably mounted on the inner wall of the sealing ring. A support plate symmetrically fixedly mounted on the housing surface has a relief groove formed on its surface, and a symmetrical circular groove is formed on the inner wall of the relief groove. A rotating rod rotatably mounted on the inner wall of the circular groove, and a torsion spring is mounted on the surface of the rotating rod. The heating rings can heat and sterilize the eye drops within the barrel, and the heating rings are easily removable, facilitating inspection and maintenance. The rotation of the stirring rod can not only quickly stir the eye drops to accelerate sterilization, but also crush crystals. The setting of the filter element can not only perform secondary sterilization on the eye drops, but also filter out impurities. The filter element is easy to remove and replace.

[0004] However, the above-mentioned method of sterilizing the base water of the eye drops adopts a heating ring to heat the base water for sterilization. However, the impurities and heat-resistant bacteria in the base water cannot be killed in time by the heating ring of the cylinder. The single heating ring heating base water sterilization method affects the cleanliness of the base water sterilization. Utility Model Content

The air guide pipe is then connected to the steam delivery pipe, and the steam enters the diverter pipe. After the steam is dispersed, it is discharged from the through-holes of the mesh cylinder. The high-temperature steam contacts the base water in the sterilization barrel and sterilizes the base water at high temperature. At the same time, the diverter pipe is started to rotate on the screw cover, and the rotating mesh cylinder stirs the base water flow, increases the fluidity of the base water, and ensures the uniformity of the base water sterilization. Then, the disinfectant is added into the sterilization barrel through the dosing cartridge to sterilize the base water. The water pump on the straw is started to suck the base water in the sterilization barrel into the filter cylinder and the base water is discharged through the straw. The dosing piece, air guide piece and dosing cartridge are used to complete the filtration sterilization, heat sterilization and chemical sterilization of the base water, which meets the requirements of sterilizing the base water. The multiple sterilization methods increase the sterilization range and effect of the base water, which is beneficial to the subsequent online production in the production line.
