“Accidental inconvenience has inspired my invention.†Teacher Wu Xianzhong of the First Experimental Primary School in Tongliang County said that in April of last year, he bought a bottle of eye drops because of eye discomfort, but he was holding an eye-drop bottle and carrying his head. For a long time, it was difficult to accurately instill in her own eyes. As a result, my face was full of drops and it was inconvenient.
Two improvements patented
The liquid in the spirit level is filled with liquid. The medicine in the bottle is also liquid. Can it be combined into one? Soon after, Wu Xianzhong also developed a second-generation product that will skillfully turn the eyedropper into a horizontal ruler, make the bottle body into a cone, and make the mouth of the bottle under the cone, and then make a circle around the bottom of the cone. The horizontal line perpendicular to the axis of the bottle. Fill the bottle with liquid medicine, and adjust the angle of the bottle mouth downwards. When the liquid edge line is concentric with these circular horizontal lines, the bottle body is vertically downward. Slightly squeeze the eye drop bottle to drop the medicine. Into the eyes.
"But this eyedrops bottle is still not easy to pack, when the liquid is too much, it is not easy to observe." Wu Xianzhong improved again, the eye drops bottle is divided into two parts: the above is a rectangular or spherical liquid part, the instillation part below A spherical leveler also makes a circular horizontal line perpendicular to the central axis of the bottle; there is a small hole connection between the two parts, which can not only allow the medicine to pass through smoothly, but also control the dosage of the potion in the spirit level. When the drip part of the liquid edge line is in a concentric circle with the horizontal line, the bottle is squeezed and the liquid is accurately dropped into the eye.
Wu Xianzhong filed a patent application for a new type of eyedrop bottle he invented to the national patent office. Recently, Wu Xianzhong received a patent certificate from the National Patent Office.
How can I ensure eye drops trickle into my eyes? Wu Xianzhong found that the reason why the medicine could not be dropped into the eyes was because the eyes were not on the vertical line where the medicine dripped. If you keep your eyes on this vertical line, can you drop eye drops into your eyes?
This discovery made Wu Xianzhong excited. The first thing that came to mind was the addition of an auxiliary drip solution to the eye drops. He decided to install a level rule around the eye drops, so that when the patient drops his own eye drops, he can constantly adjust the direction of the eye drops by observing the air bubbles in the level ruler until the eye drops straight down. Eye drops, it is easy to dribble into your eyes.
