Description

The invention relates to medical equipment and can be used for independent outpatient or stationary drip of drugs into the nose or eyes of the patient.

For droplet counting and drug administration, there are droppers made at the same time as the drug reservoir, removable droppers that are worn on the outlet of the drug reservoir after opening it, and ordinary pipettes. The main requirements for droppers are ease of use, compactness, safety and cost-effectiveness.

The most famous and traditional are droppers in the form of a tube equipped with a rubber cap. They operate on a pipette basis and are sold in pharmacies separately from drug reservoirs. Drops for external use (ear, eye, and others) can be dispensed using dropper droppers with ground stoppers in the form of dropper-dropper shapers (Medical Encyclopedia. - M.: Soviet Encyclopedia, v.10, p.274, 1979). The disadvantage of the described droppers is their fragility, which creates inconvenience during operation and transportation. The emergence of new materials - plastics that meet medical requirements, allowed us to create droppers that are safe in operation and transportation.

So known dropper according to US patent No. 4673397, p. 16.06.87, with a device to reduce the possibility of the formation of reverse bursts of drops. The dropper has an elastic plastic chamber with an outlet for communication with a device for forming drops and an outlet. It is also equipped with a device to reduce the possibility of forming reverse splashes of drops in the form of relief elements on a part of the inner surface adjacent to the liquid level in the latter. The disadvantage of this dropper is the complexity and integrity of the design, which does not allow the device to be used for drugs that need to be sterilized.

The closest and selected as a prototype is the device according to Swiss patent 66561 OA, having an elastic plastic cover for placement on the tank, a camera with an outlet for communication with a device for forming drops in the form of a tube. The disadvantage of this device is the impossibility of its use for drugs that require sterilization.

The objective of the invention is to expand the arsenal of removable plastic droppers for medicines.

The technical result that can be obtained by using the claimed invention is to increase ease of use; the possibility of using funds that require sterilization before use.

The solution of this problem and the achievement of the above results became possible due to the fact that in the well-known medicine dropper, including a round removable plastic lid with a side rim, designed to be placed on the outlet of the tank, and a drop former made of plastic in the form of a body of revolution, the drop former is integral with the lid perpendicular to it, has the shape of a truncated cone with a through channel tapering to the working end and is offset relative to the axis of rotation eniya reservoir to the edge of the lid, and the lid has a thinned central portion for pressing when applying drops and is adapted to accommodate at rest on the tank drops to generator arranged along the vessel wall.

Making the horizontal part of the lid more refined facilitates the use of a dropper due to the possibility of pressing it with one finger and removes the restriction on the height of the drop former.

Transferring the drop former to the edge of the lid allows you to create a space for the refined central part to be pressed when dropping drops and create a removable lid that, when turned upside down, takes up a minimum of space in an individual package, which, in turn, does not increase the consumption of packaging material. The lateral spatial arrangement of the drop former also provides ease of use by bringing the drop former closer to the face of the patient.

The invention does not explicitly follow from the prior art. The technical solution has not been identified from the prior art, the combination of features of which is identical to the essential features of the claimed invention.

The invention is illustrated by the following figures: figure 1 - dropper for drugs (section aa); figure 2 is a reservoir with a medicinal product, closed with a dropper at the time of use (section along aa); figure 3 is the same; 4 is a closed reservoir with a medicinal product and a dropper lying on it with an inverted drop former in an individual package.

The claimed dropper for drugs is a circular removable cover made of plastic with a side rim 1 and the upper part 2, made spherical with a thinned central part 3 for pressing when applying the drops (figure 1). The drop former is made of plastic in the form of a truncated cone 4 with a through channel 6 tapering to the working end 5.

A dropper for drugs works as follows: the reservoir 7 with the drug 8 is opened, the claimed dropper is put on its outlet 9 and either the resulting system is completely turned upside down or partially, in the latter case, the dropper is placed at the bottom (FIGS. 2 and 3). The patient presses finger 10 on the refined central part 3 for pressing when dropping drops and the formed drop 11 through the tapering through channel 6 is detached from the working end 5 and enters the patient’s cavity (nose, eyes). In the idle state, the reservoir 7 with the drug 8 is closed hermetically by a lid 12 and placed in an individual package 13 (figure 4). The dropper is turned upside down and placed on the cover 12 of the tank 7 with an offset, and the drop former is compactly located along one of the walls of the tank 7.

The industrial applicability of the claimed dropper is shown in the following specific use example.

Example.

The tank with naphthyzine has a height of 4 cm, the outer diameter of the outlet is 1.0 cm, the inner diameter of the lid is 1.01 cm. After opening, at the time of use, the tank is closed with a dropper, the diameter of the thinned central part for pressing when dropping is 0.7 cm, the drop former is 3 cm high. When pressed with a finger on the thinned central part to press, droplets are formed which form middle drops that separate well from the working end of the drop former. The effort of pressing the refined central part to be pressed during the supply of drops is minimal.

The consumption of packing cardboard for the assembled dropper and reservoir is almost equal to the expenditure for one reservoir with the drug.

As can be seen from the example, the claimed dropper is operable, the injection mold for its manufacture is simple.

In operation, the inventive dropper is convenient. When producing drugs in an individual cardboard package with a dropper component, the individual package practically corresponds in size to its size, as noted above, i.e. packaging of some tanks, respectively, and the size of the group box increases minimally.

Thus, only the claimed combination of essential features allows expanding the arsenal of removable droppers for drugs due to the compact, economical and easy-to-use dropper for drugs, which can also be used for products that require sterilization before use, which makes it competitive.

Claims (1)

A medicine dropper, including a circular removable lid made of plastic with a side rim, designed to be placed on the outlet of the tank, and a drop former made of plastic in the form of a body of revolution, characterized in that the drop former is integral with the lid, perpendicular to it, has the shape of a truncated cone with a through channel tapering to the working end and is displaced relative to the axis of symmetry of the tank to the edge of the lid, and the lid has a thinned central part for pressing when droplets and made with the possibility of placement inoperative on the tank with a drop former located along the wall of the tank.
