Description

A precise medication dispensing device for ophthalmology

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a precise medicine dispensing device for ophthalmology.

Background technique

Eye drops are the most common specialist operation for ophthalmic nurses. Currently, due to the differences in medication between different subspecialties, different types of diseases, special patients and special eye conditions of patients, there are different needs and difficulties in applying eye drops.

The normal adult conjunctival sac can hold up to 30 microliters of liquid, of which 7-9 microliters are tears, so the conjunctival sac can hold up to about 20 microliters of eye drops. The existing eye drop bottle can drip about 30-39 microliters of eye drops, which is far more than the capacity of the conjunctival sac. There will definitely be a little overflow after the medication is applied, but the amount of one drop of eye drops is enough. The amount of medication for special patients: The conjunctival sac of infants, small eyelids, blepharoplasty, and highly swollen conjunctiva (or eyelids) cannot hold 20 microliters of liquid, and the overflow is more serious, which often causes the patient's family or nurses to feel that the drops have not been applied, and they repeatedly apply the drops.

Existing eye drops have the following shortcomings:

1. Repeated application of the medicine will stimulate tear secretion and dilute the medicine, affecting the efficacy;

2. Most eye drops contain preservatives. Repeated use increases the absorption of preservatives, which can easily lead to dry eyes and corneal diseases in the long term.

3. Waste of liquid medicine reduces patients' trust in nurses, especially since some special eye drops are relatively expensive. Wasting liquid medicine increases the financial burden on patients.

Therefore, how to solve the above technical problems is a technical problem that needs to be solved urgently by those skilled in the art.
