Description

Technical Field

[0001] The utility model relates to the technical field of contact lens care solution, in particular to a moisture retention effect detection device for contact lens care solution. Background Art

[0002] The contact lens care solution has a moisturizing effect on the contact lenses. After the contact lenses are soaked in the care solution and then taken out for use, the contact lens care solution will infiltrate and wrap the contact lenses, thereby having a moisturizing effect on the contact lenses.

[0003] During the use of contact lens care solution, the contact lenses are washed by human tears or other external liquids such as alcohol and water, which will cause the moisturizing ingredients in the contact lens care solution on the contact lenses to be washed away, resulting in water loss in the lenses and discomfort such as dryness when worn. The washing by human tears is a long process. The existing tests are usually performed on lenses that have just been soaked in contact lens care solution. There is a lack of data on the moisturizing effect after being washed by human tears or other external liquids after wearing. Therefore, it is necessary to test the moisturizing effect of the contact lens care solution after being washed. Therefore, a moisturizing effect testing device for contact lens care solution is proposed. Utility Model Content

[0006] The tops of the three pipes of the three-way pipe are all fixedly connected with a liquid inlet hopper, the top of the liquid inlet hopper is snap-connected with a sealing cover, and the three pipes of the three-way pipe are all provided with solenoid valves.

[0007] Furthermore, a motor is arranged inside the base, an electric push rod is fixedly connected to the top of the output shaft of the motor, a U-shaped rod is fixedly connected to the piston of the electric push rod, and an electric suction cup is fixedly connected to the bottom of the U-shaped rod.

[0008] Furthermore, the output shaft of the motor passes through the top wall of the base and is rotatably connected to the top wall of the base, and the bottom of the electric push rod is rotatably connected to the top wall of the base.

[0009] Furthermore, the glass slide is located on the top of the base, a groove is formed on the glass slide, a contact lens buckle is placed in the groove of the glass slide, and a contact lens body is attached to the top of the contact lens buckle.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The moisturizing effect detection device for contact lens care solution is as follows: when artificial tears are dripped onto the contact lens body, the electromagnetic valve on the pipe on the three-way pipe storing the artificial tears is opened, the electromagnetic valves on the pipes on the three-way pipe storing alcohol and distilled water are closed, the delivery pump pressurizes the three-way pipe so that the artificial tears overflow from the liquid outlet pipe to flush the contact lens body; when alcohol is dripped onto the contact lens body, the electromagnetic valve on the pipe on the three-way pipe storing the alcohol is opened, the electromagnetic valves on the pipes on the three-way pipe storing the artificial tears and distilled water are closed, the delivery pump pressurizes the three-way pipe so that the alcohol overflows from the liquid outlet pipe to flush the contact lens body; when distilled water is dripped onto the contact lens body, the electromagnetic valve on the pipe on the three-way pipe storing the distilled water is opened, the electromagnetic valves on the pipe on the three-way pipe storing the artificial tears and distilled water are closed, the delivery pump pressurizes the three-way pipe so that the alcohol overflows from the liquid outlet pipe to flush the contact lens body; The solenoid valves on the pipes on the three-way pipe for storing artificial tears and alcohol are closed, and the delivery pump increases pressure in the three-way pipe, so that distilled water overflows from the liquid outlet pipe to flush the contact lens body. After the artificial tears, alcohol and water flush the contact lens body, they will form a mixed liquid with the care solution on the contact lens body and be stored in the groove of the slide. The excess mixed liquid will overflow from the groove. After the contact lens body is quantitatively flushed with artificial tears, alcohol and water, the content of moisturizing components of the contact lens care solution in the remaining mixed liquid in the groove is detected, which can simulate the flushing of the contact lens stained with the contact lens care solution by human tears, alcohol and water, so that the user can detect the moisturizing effect of the contact lens care solution after flushing.
