Description

DEVICE THAT DECREASES THE RISK OF OVERDOSE WHEN USING PIPETTES OR DROPPERS FIELD OF THE INVENTION The present invention relates to a device for handling and supplying liquids, in particular medicines, which are supplied orally, with the possibility of simultaneously measuring and controlling the quantity supplied. More specifically, it refers to a new device for handling and supplying liquids with the quality of reducing the risk of overdose.

BACKGROUND OF THE INVENTION The operation of administering liquid or semi-liquid medicines, orally, has been carried out by means of a myriad of devices, from the simple coffee or soup spoon, to complex dis-positives that have taken into account more than Another thing for its design, is the precision in the measurement of the quantity to be supplied (the dose), passing through the droppers, with or without graduation.

A device that has solved in a quite acceptable manner, simultaneously, with simplicity and precision, the problem presented by the previously used supply and measurement devices, was the device that is described and claimed in the patent application EP 93201995.3, of filing date July 8, 1993.

The novel device described, not only allowed to supply and dose the medication to be provided, with an important simplicity, but also gathered qualities that made them safe in the sense of preventing a child from taking medication from the bottle or bottle.

Both the dropper and the device of the aforementioned patent application had the additional advantage of facilitating the passage of the device from the device to the patient's mouth. This advantage is very important especially when the patient is a small child. Because of their configuration, these two types of device easily allow the introduction of the tip into the child's mouth, and at the same time the risk of spilling part of the medication is almost nullified.

However, despite all these qualities, both the dropper and the dosing pipette of the EP patent application 93201995. 3, have in common the problem that, for a part, the outer surface of these devices, relative outer surface that is quite important, gets wet with the medicine. Second, this outer surface will be in contact with the patient's mouth. The problem intensifies with the more viscous medications, and with those of higher surface tension, since these qualities, being larger, cause a greater amount of medication adhered to the outer wall of the dropper or pipette.

It was found that the amount of medication that is dragged from the bottle to the mouth of the baby or child, can represent 10% of the prescribed dose. On the other hand, this amount dragged can drip into the mouth of the child or baby or even it can lick or suck that amount of medication.

To date, not only is there no document that presents a solution to this problem outlined, but even this problem has not been noticed and no document has disclosed it. Based on this, it is possible to conclude the need for a device that alleviates or completely solves the problematic situation.

OBJECTIVES OF THE INVENTION Based on the above, one of the objects of the present invention is to make possible a device that reduces the risk of supplying an overdose, by medication adhered to the external surface of the dispenser.

Another objective is to make possible a device with the previous function, with the characteristic as well as simplicity in its structure, ease of manufacture and long service life.

Still another objective is to allow that device to be perfectly coupled, to the existing structures of pipettes and dosing drippers, without additional space requirements.

Another objective is to make possible a device that without changes in its structure, allows its addition to existing structures despite the versatility of them.

And all those qualities and objectives that will become apparent when making a description of the present invention, supported by the illustrated modalities.

SUMMARY DESCRIPTION OF THE INVENTION Before proceeding to the description of the invention, it is convenient to remember the basic structure of the dosing devices, which together with the scraper device, integrate the structure object of the present invention, for a better understanding thereof.

The description of this dosing device was originally made in the European patent application EP 93,201995.3 dated July 8, 1993, which gave rise to an American patent US 5,746,349, to a European patent application EP 19940924711, an international PCT application / EP94 / 02149 and a Mexican patent application 9405195, the latter with the priority date of the original European application.

The basic structure of these dosing drippers or pipettes consists of a cover with a central hole through which a hollow cylinder is passed, that when a cap and cylinder are installed in a bottle or bottle of the medication to be supplied and dosed, said cylinder extends axially. until near the bottom of the bottle or jar. Said hollow cylinder has an open upper end and a closed lower end with a central opening.

This device also comprises another cylinder fitted to the first outer cylinder in its inner part, on at least a part of its surface. The outer cylinder has marks of the volumes of liquid that it can contain according to the level reached by said liquid.

The operation of this dosing device begins by introducing it into the bottle with the medication to be dosed. In one of the embodiments, the device is fixed to the bottle or bottle by means of the lid that may comprise the dosing device. The inner cylinder slides out, creating a vacuum in the outer cylinder and thus pumping the liquid medication inside. The outer cylinder with the inner cylinder is slid out and placing the lower end in the infant's mouth, the liquid is impelled to pass it to it.

It is at this point of the procedure that the liquid that adhered on the outer surface of the outer cylinder can be absorbed by the infant and receive an overdose for the same.

In coarse form, the scraper device consists of a hollow conical central projection of the lid element that is used to fix the dropper or dosing pipette to the medication bottle or bottle, said projection being directed downwards from the lower face of said lid in its central area. Said hollow conical central projection has a series of radial cuts directed from the lower end towards the upper end without reaching this. These cuts make it possible for the segments of the cone formed by the cuts to deform and allow the passage of said outer cylinder by sliding the outer cylinder into the central hole of the cover.

The deformation mentioned in the outer paragraph, although they allow the passage of the outer cylinder of the dosing device, the passage is made in a form adjusted in such a way that said segments sweep the adhering liquid, draining it to the inside of the bottle, by the conical shape , with the vertex down.

In said scraper device, the material of which it is made, the flexibility thereof, the number of slots and the length thereof are associated for its proper functioning. As an example, the more slots are practiced and the longer the slots, the softer the grip.

By introducing the dosing device into the liquid medicament, the outer surface of the dosing cylinder is impregnated or "wetted" with said medicament. As the dispensing device slides out, since the deformed segments of the scraper device are in contact with the outer surface of the cylinder, they perform a scraping operation by sweeping the liquid toward the lower end of the cone at its outer surface.

The scraper device, which in its preferred embodiment can form a single body with said lid, can also be threaded to be fixed in this way to the lid, or to the back cover. Their sales would be from the point of view of manufacturing. Due to its qualities, the scraper device can be integrated into the back cover when the dosing device comprises a childproof safety cover, or in the lid, when the lid of the device is simple.

This description, which illustrates the invention in its general aspects, has different modalities in each of its elements, in the present invention a preferred embodiment will be described in detail, and another modality will be mentioned briefly, even though it is not the preferred one.

For a better understanding of the invention, description will be made of one of the modalities thereof, illustrated in the drawings that are annexed to the present description for purposes of illustration, but not limitation.

BRIEF DESCRIPTION OF THE FIGURES The characteristic details of this structure in one of the preferred embodiments will be illustrated in the following figures.

Figure 1 illustrates the assembly of the dosing device integrating the present invention in an exploded perspective view.

Figure 2 illustrates a section of the dosing device assembly with the integration of the invention in a bottle.

Figure 3 shows the detail of the scraper device in the fashion illustrated in Figures 1 and 2.

DETAILED DESCRIPTION OF THE PREFERRED MODALITY The characteristic details of the present invention are described below, relying on the accompanying drawing and serving the same reference signs to indicate the same parts.

Figure 1 illustrates the assembly of the dosing device integrating the present invention in an exploded perspective view. In this mode the dispenser has a childproof lid formed by lid 3 and back cover 2 where in addition to turning the lid it is necessary to push or push it down, so that the bottle can be uncapped. The scraper device is marked with the number 6 and the dosing device is formed by the plunger 5 and the cylinder 4.

Figure 2 illustrates a section of the dosing device assembly with the integration of the invention in a bottle. These elements are the same as in figure 1, but show the detail of the deformation of the scraper device segments. In its state without deformation, the undeformed segments 7 of the scraper device deform to remain deformed segments 8 when the cylinder 5 of the dosing device passes through the back cover.

Figure 3 shows the detail of the scraper device in the embodiment illustrated in figures 1 and 2. The back cover 2 is molded in one piece to the scraper device 6 in conical shape with the apex facing downwards. The segments 7 are formed by means of the cuts 9, which when deformed by the dosing device are deformed as shown in figure 2 by the number 8.

The inventive concept of the scraper device can be thought of as part of the dosing device as we have done so far, however it is possible that this device forms part of the bottle with medication. Two modalities of the invention are then presented, the first of which is that the bottle with the medicament is distributed with a common cap and current, and attached to this bottle comes the dosing device integrated to a normal or childproof cap. Said lids comprising the scraper device.

The other option is that the cover with the scraper device is already integrated into the bottle. The lid would comprise a membrane that would cover the hole through which the dosing device is to pass and the cuts in the scraper device would be replaced by weakening, which unless some object had already been passed through, would keep the segments united taking the contents of the bottle isolated from the outside.

Membrane and weakening would be safety seals that would fulfill the objective of keeping the bottle closed and the objective of signaling when a bottle had already been violated. The cover, simple or child-proof in addition, could have any mechanism already widely known to indicate whether or not it has been previously removed from the bottle.

In case the lid is normal and not a child-proof lid, the scraper device would obviously be attached, attached, fixed or forming a single body, with the lower surface of said lid, since there would be no back cover.

The invention has been described sufficiently so that a person with average knowledge in the art can reproduce it and obtain the results that we mentioned in the present invention. However, any person skilled in the art who is competent in the present invention may be able to make modifications not described in the present application, however, if for the application of these modifications in a certain structure or in the manufacturing process thereof, the matter claimed in the following claims is required, said structures should be included within the scope of the invention.
