The invention discloses an eyedrop box for ophthalmology treatment and a using method thereof, and relates to the technical field of eyedrops. The eyedrop box comprises an equipment body, a liquid medicine remaining amount judging assembly, a driving assembly, an identification and drilling linkage assembly and a control module. A storage bin is formed in the equipment main body and is provided with a sensor; the liquid medicine residue judgment assembly realizes visual judgment of the residue through linkage of a moving plate, a shielding cover and an identification rod; the driving assembly provides power for marking and drilling. The marking and drilling linkage assembly realizes'dye marking + drilling for preventing secondary filling 'of empty bottles and'only dye marking' of expired bottles through the rotating direction difference of a rotating disc; the control module controls all the assemblies to act through a PLC program. The problems that an existing eyedrop box cannot visually judge the remaining amount, has no expiration reminding function and has no empty bottle secondary filling prevention function are solved, eye safety risks can be avoided, and different user requirements are met.

The invention relates to a device for delivering a dose of a mist of an ophthalmic liquid, the device comprising a housing having: a holding chamber having a discharge opening, the holding chamber being for holding a dose of liquid to be delivered; a pump (200) for pumping a dose of liquid to the holding chamber (92) via a dose supply conduit (235); the pump (200) being connected to a container (30) containing a plurality of doses; an airflow conduit (76; 77) for supplying an airflow to the holding chamber (92) in order to force a dose delivered by the pump (200) to the holding chamber (92) out through the discharge opening (93).

The invention relates to the technical field of ophthalmology devices, and particularly discloses an ophthalmology medicine dropping device which comprises a bottle body, a bottle cap and a bottle cap. The eyedrop bottle further comprises an eyedrop dripping assembly which is arranged in the bottle body and used for dripping eyedrops. The height adjusting assembly is arranged on the outer side of the medicine dripping assembly, and the height adjusting assembly is used for adjusting the height of the dripped medicine liquid; the flow adjusting assembly is arranged at the bottom end of the bottle body, and the flow adjusting assembly is used for adjusting the flow of the dripping liquid medicine; the opening electrifying assembly is arranged in the bottle body, when the touch block presses the limiting switch, the piston directly pushes the liquid medicine guided into the chamber into the corrugated pipe, and therefore the process of extracting the liquid medicine by the piston is adjusted, and the amount of the dripped liquid medicine can be adjusted according to the difference between children and adults; therefore, the treatment effect is improved, and better flexibility and applicability are achieved.

A device (200) for the delivery of a mist of a dose of an ophthalmic liquid configured for communicating with a data processing unit (190) providing an output representing operation of the device based on at least one sensor input comprising a dispersion unit (90) with a housing (92) having a discharge opening (130) for a mist of a dose of an ophthalmic liquid and a sensing unit (100) to be positioned in front of an eye and comprising a first sensor (10) for detection of the mist and communicating with the data processing unit (190), for the data processing unit (190) to register when the first sensor (10) detects the mist.

The utility model discloses a children's eyedrop device, including instillation main part, grading dropper and dropper, instillation main part inside is provided with liquid storage chamber, and the liquid storage chamber is provided with instillation opening, grading dropper is communicated and installed at instillation opening, grading dropper far away from instillation main part one end is communicated and provided with the dropper, and the dropper is provided with the dropper. The grading dropper comprises a large-caliber dropper, a medium-caliber dropper and a small-caliber dropper which are arranged in sequence, the large-caliber dropper is communicated with the dripping main body, and droppers are arranged at the ends, away from the dripping main body, of the large-caliber dropper, the medium-caliber dropper and the small-caliber dropper in a communicated mode; and easy-to-break points are arranged between the large-caliber dropper and the medium-caliber dropper and between the medium-caliber dropper and the small-caliber dropper. According to the eye drop device for children, by means of three selectable liquid outlet modes with different liquid outlet amounts, convenience, safety and comfort of eye drop dropping for children are achieved through the unique design, and the efficiency and quality of ophthalmic nursing for children can be improved.

A device (1) for dispensing a mist of a dose of an ophthalmic liquid, comprising, a discharge opening (93) for the mist, a mixing chamber (21) being in fluid flow communication with the discharge opening (93), an air chamber (50), being in fluid flow communication with the mixing chamber (21), a container (30) holding a first volume of liquid corresponding to a plurality of doses of the liquid (L), such as a collapsible liquid container or a liquid container having a movable bottom, a dose holding chamber (92) for holding a second volume of the liquid and being in fluid flow communication with the mixing chamber (21), and being in fluid flow communication with or configured for being in fluid flow communication with the container (30), a first drive (52, 58) operable to expel air from the air chamber (50), a second drive with a piston (238), the second drive being operable to supply the second volume of the liquid from the container (30) to the holding chamber (92) and for emptying said container (30) by repetitive delivery cycles each delivering a single dose from the first volume of liquid contained therein towards the holding chamber (92) the air chamber (50) being in fluid flow communication with the holding chamber (92) for the expelled air to drive the second volume of liquid from the holding chamber (92) into said mixing chamber (21) by the expelled air characterised in that the piston (238) is displaced from an advanced position to an at least partially retracted position and / or from a retracted position to an at least partially advanced position more than once during the delivery cycle.
