Technical Field

[0001] The utility model relates to the technical field of eye drops production, in particular to an eye drops production isolation and protection device. Background Art

[0002] Eye drops refer to liquid preparations that are dropped into the eyes, also known as eye drops. They are sterile drugs whose main functions are to replenish tear lubrication, resist infection, and lower intraocular pressure. Some ingredients in eye drops can relieve eye fatigue and relieve eye discomfort when staring at the screen for a long time, reading, or other situations that require excessive eye use. Isolation and protection devices are required during the production process of eye drops to ensure that the eye drops are not contaminated. Generally, the device is passed through the wall, and then the two ends of the pipeline are connected to the liquid inlet pipe and the liquid outlet pipe respectively to realize the transportation of eye drops in the two spaces. However, passing through the wall causes gas convection in the two spaces, which leads to pollution of the spatial environment.
