Ophthalmic drug delivery system

Abstract

The invention discloses an ophthalmic drug delivery system which comprises an ultrasonic atomization sheet, a silica gel waterproof gasket, a soft rubber sealing cover, a water storage tank or a waterabsorption cotton stick, a control panel, a key switch and a battery. The ophthalmic drug delivery system is characterized in that the ophthalmic drug delivery system consists of the ultrasonic atomization sheet, the silica gel waterproof gasket, the soft rubber sealing cover, the water storage tank or the water absorption cotton stick, the control panel, the key switch and the battery, the capillary action principle is utilized that the ultrasonic atomization sheet or the water absorption cotton stick infiltrates eye drops, the eye drops are appropriately delivered to the ultrasonic atomization sheet under the action of surface tension, so that nano-scale ultrasonic atomization of the eye drops is realized, the area where the eyes can be in contact with drug mist is proper, the utilization rate of the eye drops is extremely high, no drug waste is caused, the administration process is easy, the uniformity and the absorption rate are high, fear and unmatched behaviors of child patientsin drug delivery are eliminated, and the disadvantages of the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of atomized drug delivery, in particular to an eye drug delivery system. Background technique [0002] In the prior art, eye drops are directly dropped on the eyes, resulting in a very small area where the eyes can be in contact with drugs, extremely low utilization of eye drops drugs, serious waste of drugs, difficult administration process, and poor uniformity , especially children are extremely fearful and uncooperative when instilling eye drops. [0003] The present invention adopts ultrasonic atomizing sheet, silica gel waterproof gasket, soft rubber sealing cover, water storage tank or water-absorbing cotton swab, control board, key switch to form an ultrasonic atomizing drug delivery system, and uses eye drops to directly infiltrate the ultrasonic atomizing sheet or the Describe the principle of capillary action of water-absorbing cotton swabs infiltrating eye drops. Under the action of surface tensi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an eye drug delivery system, which reasonably and effectively solves the problem that the eye drops in the prior art are directly dropped on the eye, resulting in a small area where the eye can contact the drug. The utilization rate of the drug is extremely low, the waste of the drug is serious, the administration process is difficult, and the uniformity is poor, especially the children are extremely afraid and do not cooperate when instilling eye drops
