Description

Visual automatic ophthalmic nursing dropping liquid device

Technical Field

The invention relates to the technical field of ophthalmic nursing, in particular to a visual automatic ophthalmic nursing dropping device.

Background

The eye drops bottled by the eye drops are used for direct eye dropping operation. The suspension dosage form, such as cortisone eye drops, should be shaken well before use. The eye drops should be first placed in a posture. When the medicine is dropped, the head should be tilted backwards (lying on the back), the eyelid is pulled down by hand, the dropper is close to the eye, and 1-2 drops of the medicine liquid are dropped 3-4 times a day. If the eye drops too much at one time, the eye conjunctival sac can not be stored, and the white and white eyes are squeezed to increase the blood volume and waste. The liquid medicine generally contains a preservative, and the dropping frequency is too frequent, so that the surface of the eyeball is damaged. After the drops fall into eyes, the eyes should be closed lightly for a rest of three or four minutes to prolong the contact time of the drops and the eyeballs and improve the drug effect. Traditional eyedrop bottle comprises bottle and bottle lid, is provided with bellied column pipe on the bottle, and the pipe end is provided with the medicine mouth that drips, bottle lid and bottle threaded connection. When the traditional eyedrop bottle is used, the bottle body is squeezed to extrude the liquid medicine from the medicine dropping opening. When dripping, the head should be tilted backwards (lying on the back), the eyelid is pulled down by hand, and the dropper is closed to the eye. So, this kind of mode of dripping medicine relies on patient's own sensation to come the position of dripping medicine mouth and eye well, and patient's eyes can not see the position of dripping the medicine mouth, often causes to drip the phenomenon outside the eye, increases the waste on foot, and drips the medicine mouth and touch eyeball or eyelid easily, drips the medicine in-process patient and often blinks because of fear easily, influences the going on of dripping the medicine.
