Description

Auxiliary eye dropping device

Technical Field

The invention relates to a medical nursing tool, in particular to an auxiliary eye dropping device.

Background

The eye drop/eye ointment is one of the most common pharmaceutical dosage forms for treating ophthalmic diseases, and has direct and rapid treatment effect on a plurality of eye diseases. When the common eye drop/eye ointment is used, the eye drop/eye ointment needs to be dripped into a lower fornix conjunctival sac, namely a position between a lower eyelid and an eyeball of a human eye.

When the patient independently uses the eye drop/eye ointment, the eye drop/eye ointment can not be accurately dripped into the fornix conjunctival sac, and the eye drop or the eye ointment can not be clearly seen because the mouth of the eye drop or the eye ointment is too close to the eyes, so that the eye drop or the eye ointment is more easily polluted and wasted by the old, children, people who easily shake hands and people with poor eyesight. For use of eye ointments, a long strip of eye ointment is often difficult to break through and enter the conjunctival sac after extrusion, often extruding much less into the conjunctival sac. Even a person skilled in operation can not smoothly extrude the conjunctival sac into the conjunctival sac on the premise of ensuring no pollution.

Disclosure of Invention

The invention provides an auxiliary eye drop device which comprises a protective cap, a device head, a device body and a diaphragm valve, and is characterized in that the device head is arranged at one end of the device body, the diaphragm valve is arranged in the device body, the opening direction of the diaphragm valve faces to the device head, the protective cap is movably buckled at the free end of the device head, the diaphragm valve is formed by overlapping two semicircular thin slices which are arranged oppositely, and a plurality of openings are arranged at the overlapping part in a staggered mode.

Furthermore, the distance between the diaphragm valve and the free end of the head of the device is 1-2mm, the length of the head of the device is 3mm, and the diameter of the inner opening of the free end of the head of the device is 1.5 mm.

Further, the material of the head of the device comprises plastic and silicon gel.

Further, the inner side of the free end of the device body is provided with a thread.

The using method comprises the following steps: the eye drops/eye ointment are installed on the device body by opening the cover and screwing, when the eye drops/eye ointment are squeezed forcibly, the overlapped part of the diaphragm valve is pushed to deform and move forward, the eye drops/eye ointment enter the head of the device through the diaphragm valve, when the extrusion amount is enough, the force applied to the eye drops/eye ointment is stopped, and at the moment, the diaphragm valve rebounds naturally to block the eye drops/eye ointment from continuously entering the head of the device.

The invention has the beneficial effects that:

(1) the head of the device is made of soft materials such as silica gel, the device can contact the conjunctival sac without causing damage, the strip-shaped eye ointment can be smoothly disconnected by lightly touching the conjunctival sac, the waste and pollution of the medicine are avoided, the time is saved, the pain of a patient is reduced, and the accuracy of medicine application is ensured.

(2) The bottle mouth is set to be 1.5mm, the volume of the conjunctival sac is about 7 mu L, the volume of one drop of water is about 40 mu L, and the reduced inner opening diameter can reduce the volume of the dropped liquid to 10-15 mu L, so that the phenomenon that excessive liquid overflows out of eyes to pollute the skin and reduce the waste of eye drops or eye ointment is mainly considered.
