Description

DRIPPER FOR VERTICAL APPLICATION OF SOLUTIONS

TECHNICAL FIELD OF THE INVENTION

The present invention is related to the technical field of mechanics and medicine, since it provides a dropper for vertical application of solutions.

BACKGROUND OF THE INVENTION

An eyedropper or dropper is a hollow tube with a conical shape at the bottom and closed at the top by a rubber knob or thimble.

It is used to transfer small amounts of liquid by pouring it drop by drop.

In laboratories where chemicals are used, they are widely used to add reagents, indicator liquids or small amounts of product.

Its use is not recommended when precision is required in the amount of liquid poured. For these cases there are more appropriate instruments such as the pipette or the burette.

The dropper works by the pressure difference. According to Pascal's principle: "If a pressure is exerted at a point in a fluid, it is transmitted instantaneously and of equal intensity in all directions". This would allow the serum from the dropper to enter the blood without problems.

Traditional droppers evolved according to the need to dose more viscous substances, since, Due to its configuration, it could not be used with these types of substances, so the rubber knob or thimble was removed and the conical part was placed directly on the neck of a bottle, which allowed the substance to be dosed at the time of flip the jar over. Today this type of dropper is still used to dose a wide variety of substances.

A search was made of the state of the art of drippers for vertical application of solutions, where it was found that different mechanisms have been developed for this purpose, as mentioned in the patent application of the United States of America number US3640274 (A), published on February 8, 1972, with the title "EYE SPRAY DEVICE THAT HAS MIRROR", which describes a self-contained device for administering to an eye a burst of mist containing medicine, comprising a portable, normally vertical, self-supporting container that contains a delivery of said medicament, a closure member mounted on and closing the container when a burst of mist is discharged to an eye of a user, a discharge tube mounted on said closure member and including a dispensing nozzle, operable dispensing means manually mounted in said container, said dispensing means being normally positioned in a non-releasable position and being manually moved to a dispensing position by a user to propel medicated solution from said container through said tube and out of said dispensing nozzle, and a mirror connected to said container and positioned relative to said container and said dispensing nozzle to that during the treatment the user can observe the reflection of his eye in said mirror. European application number EP0685218 (Al) was also found; published on September 30, 1998, with the title "PORTABLE FIRST AID APPLIANCE TO WASH AN EYE AND / OR THE SKIN", said document describes a portable first aid device for washing an eye and / or skin with a washing liquid, said apparatus comprises a pressurized liquid reservoir equipped with an outlet valve and a liquid distributor device operatively associated with the valve; The dispensing device comprises a member for adjusting the jet of liquid exiting the valve, this member being adjustable from a first extreme position for which the dispensing device projects a jet of finely sprayed liquid to a second extreme position for which the device The dispenser dispenses a substantially continuous circulation of liquid, and comprises an eyewash that is functionally active at least when the adjusting member is in the second extreme position to collect the liquid dispensed in continuous circulation to bathe the injured eye.

Another document found is a British patent application number GB2328876 (A), published on March 10, 1999, which has the title "SPRAY DISPENSER FOR EYE MEDICATION" said document describes a dispenser with a fine spray pump for eye medication, with a flexible base for universal attachment to any open medication container. The invention comprises a fine spray pump mechanism with a conical flexible cap fitting, located at the base of the pump, in which the open top of any drug container can be secured at the widest end and, located at the spray outlet, a cup attachment, open at both ends and standard eye shape and proportion.

Finally, the European patent application number EP0986354 (Al); published on March 22, 2000 under the title "EYE FLUID APPLICATOR" which describes an eye fluid applicator comprising a) a handle portion having a distal end and a proximal end, defining the distal end and the proximal end an axis between the two and a distal direction and a proximal direction along said axis, b) a container, or a seat for a container, having a bottle portion and a delivery port for delivering a jet or drops, the orifice defining a fluid supply axis and a fluid supply direction, along said axis, from the bottle through the orifice, the orifice with its orifice being arranged closer to the proximal end than to the distal end , and c) an eye cup portion having a rim and a cavity, the rim defining a contact plane, a contact axis; normal to said contact plane and a contact direction, along said contact axis, from the cavity towards the rim, the eye cup being arranged in the hole, characterized in that the proximal direction of the handle and the direction of eye cup contact, handle / cup, form an acute angle between them.

None of the aforementioned documents shows that a dropper for vertical application of solutions has a dispensing tip through which the substance contained in the bottle comes out, where the dispensing tip has a bevel on its circumference, allowing an adequate contact surface, that allows placement of the dropper on the edge of the lower eyelid without damaging the eye, to later dose the lubricating drops into it. None of the mentioned droppers is used for lubricants, gels, oily substances.

OBJECT OF THE INVENTION

It is, therefore, an object of the present invention to provide a dropper for vertical application of solutions, which solves the aforementioned problems.
