Description

eye drops aid

technical field

The utility model relates to the field of auxiliary medical equipment, in particular to an eye drop auxiliary device used when dropping eye drops.

Background technique

Proper instillation of eye drops is critical to the successful treatment of patients with eye diseases. Due to the particularity of eye anatomy and physiology, eye drops (eye drops) are the most commonly used dosage forms for patients with eye diseases. They have the advantages of high local concentration, convenient use, and easy acceptance by patients, and are widely used.

The traditional method of eye drops is to put the patient in the supine or sitting position, with the head tilted slightly, hold the eyedrop bottle with the thumb, index, and middle fingers of one hand, with the opening of the bottle 2-3cm away from the eyes, and place the index finger of the other hand on the lower eyelid margin, and gently pull Open the lower eyelids to expose the conjunctival sac, drop a drop of eye drops into the lower fornix, close the eyelids lightly, so that the eye drops are evenly distributed in the conjunctival sac, and instruct the patient to close their eyes for 3-5 minutes. In order to ensure the curative effect, the correct method of instilling eye drops requires: ①The mouth of the eye drop bottle should be 2-3cm away from the eye, and the eye drop bottle should not touch the eyelashes and eyes to prevent cross-infection. ② Drop the eye drops on the lower fornix (that is, the depression at the junction of the lower eyelid conjunctiva and the eyeball), not on the cornea. Because the cornea is sensitive, being stimulated by the drug will cause a reflexive eye-closing action, and the drug solution will be discharged out of the eye, failing to achieve the purpose of drug administration. ③The amount of instillation is preferably 1 drop, because the conjunctival sac has a capacity of 30 μL, and the normal conjunctival sac contains 10 μL of tears, which can accommodate up to 20 μL of eye drops. Too much eye drops can not only be tolerated, but also stimulate the eyes. cornea, causing reflex tear secretion, resulting in accelerated flushing and drainage of the medicinal solution, affecting the curative effect.

The traditional method of self-instilling eye drops is difficult to master: if it is too high, it is difficult to ensure the accuracy of instillation into the conjunctival sac; Studies have shown that after 24 hours of eye drops use, there is bacterial contamination at the mouth of the bottle, and they are all pathogenic bacteria. The positive rate of bacteria increases with the number of days the eye drops are used. In addition, the traditional method of instilling eye drops is often repeated due to inaccurate instillation, resulting in a large waste of eye drops. When instilling eye drops, you need to place the index finger of one hand on the lower eyelid margin, gently pull the lower eyelid to expose the conjunctival sac, and squeeze the eye drops bottle with the other hand to add eye drops. Bacteria are often carried on the hands, and opening the eyelids with hands can cause eye infections. If the eye drops are improperly used, the operation method is not standardized or the medicine is dropped incorrectly, it may cause adverse consequences such as eye cross infection, eyeball damage, and affect the treatment effect. Therefore, it is very important to give eye drops scientifically, but many current assistive devices cannot To solve the difficulties that patients face when instilling eye drops by themselves, it is urgent to design a reasonable auxiliary device to help solve it.
