Description

Eye drop device

Technical Field

The utility model belongs to the technical field of eyes treatment auxiliary assembly, especially, relate to an eye dropper.

Background

At present, the accurate, convenient and independent operation is the characteristic of the technical attention of the existing eye dropping device, but the important eye dropping requirement of assisting the pressing of the inner canthus is not paid attention by the existing eye dropping device. The operation of pressing the inner canthus is easy to be ignored by the eye drops, the result of the step is that the eye drops flow into the nasal cavity to cause poor dosage and bad smell in the oral cavity, and the medicine in the eye drops is absorbed into the blood through the nasal cavity and the oral mucosa to cause systemic adverse reaction such as vertigo. Most of the existing eye drop devices focus on the improvement of accurate eye drop, and the important step of pressing the inner canthus in the correct operation of eye drop is ignored. Clinical practice proves that correct eye dropping and pressing of inner canthus are extremely important.

Many medicines for treating eye diseases and relieving visual fatigue are eye drops, however, currently, eye drops sold in the market at home and abroad are not provided with auxiliary eye drop devices, so that a plurality of patients cannot achieve the expected treatment effect due to improper eye drop operation, and even cross infection or adverse drug reactions can be caused.

Proper and regular use of eye drops is critical to the successful treatment of eye diseases, and the current eye drop specifications guide the following method of use: before first dropping the eyedrops, the hands should be washed or sterilized gloves should be worn, and if necessary, the eye dropping needs to be assisted by professional medical staff. Then the cover of the eye drops is opened, and one drop of the eye drops is squeezed out firstly. The patient takes the sitting position, standing position or supine position, and leans back slightly. The lower eyelid is pulled open with the fingers to expose the fornix conjunctiva with the eyeball facing upward. And (4) stabilizing the eye drop bottle body, and dripping into the conjunctiva fornix at a position 2-3 cm away from the eyeball. The lower eyelid is lifted slightly outward. Finally, the eye is closed, the nasolacrimal duct part, namely the inner canthus, is pressed, and the eyeball can be rotated for 1-2 minutes. However, there are problems with the conventional use of eye drops: (1) the liquid medicine flows into the nasal cavity due to inaccurate position or insufficient time for pressing the nasolacrimal duct at the inner canthus by fingers, so that the liquid medicine at the eyes is reduced, and the medicine effect is reduced; and can cause the liquid medicine to flow through the inner canthus or flow back into the cavity to be absorbed, thus causing adverse reaction of the whole body; (2) when a patient drops eyes by himself, the mouth of the liquid medicine bottle is often contacted with an eye conjunctiva, so that the mouth of the liquid medicine bottle is polluted, and when another eye is dropped again, cross infection is likely to be caused; (3) when partial patients drop eyes by themselves, the liquid medicine drops outside the eyes due to inaccurate focusing, so that the waste of the liquid medicine is caused; (4) because the fingers of the patient need to press the nasolacrimal duct at the inner canthus when the patient is in eye-drop, hands are washed before the eye-drop so as to avoid eye pollution or infection, and the medical staff need to wash the hands once when the medical staff drops the eyes of a plurality of inpatients because the scholars recommend the eye-drop to be operated by professional staff, which undoubtedly increases the burden of the medical staff.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) the liquid medicine flows into the nasal cavity due to inaccurate position or insufficient time for pressing the nasolacrimal duct at the inner canthus by fingers, so that the liquid medicine at the eyes is reduced, and the medicine effect is reduced; and can cause the liquid to flow through the inner canthus or flow back to the oral cavity or nasal cavity for absorption, thus causing adverse reaction of the whole body;

(2) when a patient drops eyes by himself, the mouth of the liquid medicine bottle is often contacted with an eye conjunctiva, so that the mouth of the liquid medicine bottle is polluted, and when another eye is dropped again, cross infection is likely to be caused;

(3) when partial patients drop eyes by themselves, the liquid medicine drops outside the eyes due to inaccurate focusing, so that the waste of the liquid medicine is caused;

(4) because the patient needs to press the nasolacrimal duct at the inner canthus with fingers when dropping the eye, hands are washed before dropping the eye to avoid eye pollution or infection, and foreign scholars recommend eye dropping to be operated by professionals, so that medical staff need to wash hands once when dropping the eye for a plurality of inpatients, which undoubtedly increases the burden of medical staff.

The difficulty in solving the above problems and defects is: firstly, for the people who are dropped into eyes independently and the eyes are sensitive to stimulation, the difficulty coefficient of dropping the eyedrops into the eyes accurately and rapidly is extremely high. Secondly, for medical staff or family members of patients who assist bedridden patients in eye dropping, the difficulty coefficient for solving the problems and the defects is extremely high.

The significance of solving the problems and the defects is as follows: the eye dropper has simple use method and is convenient for patients to drop eyes by themselves. Before eye drop, the bottle mouth of the eye drop is fixed at the rubber ring of the eye dropper, and then the bracket with the anti-slip foam at the bottom is fixed at the inner canthus, so that the inner canthus is effectively pressed, the medicine is prevented from entering the nasal cavity and the oral cavity through the punctum after eye drop, the eye drop is left in the eye as much as possible to ensure the medicine effect, and the systemic adverse reaction caused by the absorption of the medicine through the nasal cavity and the oral mucosa can be reduced. The other two brackets are used for respectively propping open and fixing the upper eyelid and the lower eyelid to control the opening time of the eyes, so that the eye drops are ensured to be accurately dripped into the eyes, and meanwhile, the medicine waste caused by blinking when the eyes are dripped can be effectively avoided.

The innovation point is that the auxiliary eye dropper sold at home and abroad does not consider the item of pressing the inner canthus, and the sold eye drops are not provided with the auxiliary eye dropper, so that the eye drops are inconvenient for patients to drop eyes by themselves and the aim of safe and effective medication is difficult to achieve. The purpose of the project is to design and develop an eye dropper, so that eye drops can be accurately and sufficiently dripped into eyes to ensure the curative effect, the waste of the eye drops is avoided, and the adverse effect caused by the improper operation of the eye drops is prevented.
