Description

The utility model relates to medical equipment and can be used for accurate dosing of household liquid preparations in tanks, such as herbal tinctures, water-alcohol medicines and preventive drugs.

For the convenience of using solutions of drugs or prophylactic drugs that require dosing, for example, by counting drops, there are a number of known devices in which the dispenser is combined with an element that closes the neck of the tank. So, from the analogue series, a dropper plug is known, having a flat annular rim, the outer diameter of which coincides with the outer diameter of the neck of the reservoir for the drug solution, and the inner diameter with the hole diameter of this neck. The flat ring-shaped rim with its lower part is aligned with a dropper made in the form of a cylinder, the diameter of which is equal to the diameter of the hole turning into a cone, inside which a partition is placed, forming two openings in the closed section of the cone in the form of a circle sector and a small hole under a straight section of this sector [ The alphabet of pharmaceutical packaging. Part 1. Polymeric container. Digest of the Farmupakovka catalog, position 3.7, CJSC NPF PROGRESS CENTER, St. Petersburg, 2004].

A disadvantage of the known device is the slow dosing rate. In practice, the drug reservoir must be shaken, which causes difficulties in counting the drops.

Also known is the “corvallola” dropper stopper, which also fits tightly into the neck of the drug reservoir, and

drug solution is dosed through a narrow cylindrical channel [Alphabet of pharmaceutical packaging. Part 1. Polymeric container. Digest of the Farmupakovka catalog, position 3.6, CJSC NPF PROGRESS CENTER, St. Petersburg, 2004].

A common disadvantage of the known devices that implement drip dosing is the impossibility of accurate dosing due to the receipt of different droplet sizes, depending on physical and mechanical factors such as surface tension, fluidity, temperature, hole size in droppers, etc. and drug overruns.

The task of creating a utility model is to develop a system for fast and accurate dosing of liquid drugs and prophylactic drugs in a reservoir that eliminates the loss of a liquid drug.

Technical results that can be obtained by implementing the claimed utility model are:

- Improving the accuracy of dosing;

- Elimination of losses of the dosed liquid preparation;

- Reducing the time of selection of the required dose of a liquid preparation;

- Reducing the contact of a metered drug or prophylactic drug with air.

The solution of this problem and the achievement of the above technical results became possible due to the fact that the accurate dosage system of a liquid drug or prophylactic drug from the reservoir is characterized by the presence of a stopper for the reservoir and a tube located in its lid, vertically oriented relative to the plane of this lid and protruding beyond its plane, while the inner or outer diameter of the tube allows it to fit snugly either into or on the tube

the lower cylindrical element of the body of the medical syringe having a graduated scale and piston.

In a particular embodiment of the system, the part of the vertically oriented tube from the side of the lower plane of the lid has a length sufficient to allow the selection of the drug from the bottom of the tank, and can be either monolithic or composite, and the body of the medical syringe is equipped with an additional scale, graduated in drops.

The accuracy and speed of selection of a drug or prophylactic drug and the simplicity of transferring the required dose into a glass without loss practically eliminate the irretrievable loss of the drug when it is overdosed and significantly reduces the surface contact of the drug with air, intensifying the redox processes in the moving surface layer of droplets, which in total has a large surface , as well as the risk of introducing pathogenic bacteria into the preparation from contaminated air.

The utility model is illustrated by the following figures:

Figure 1. The system of precise dosing of a liquid preparation from a container, a composite vertically oriented tube (section along AA);

Figure 2. Accurate dosing system for liquid medicinal and prophylactic drug assembly;

Figure 3. The body of a medical syringe having two scales, graduated in ml and drops;

Figure 4. Disassembled system in packaging.

The inventive system for accurate dosing of liquid medicinal or prophylactic drug 1 from the reservoir 2 (Fig. 1) has a plug 4 inserted into the neck 3 of the reservoir 2, in the cap 5 (Fig. 2) of which a tube 6 is placed, vertically oriented relative to the plane of this cap 5. The tube 6 can protrude beyond both planes

lid 5, while part 7 of this tube 6 from the lower plane 8 of lid 5 of plug 4 in a particular embodiment has a length sufficient to allow selection of the required dose of a drug or prophylactic preparation 1 from the bottom 9 of reservoir 2. Tube 6 has inner or outer diameters (not shown in Fig.), which provide the possibility of a tight fit either into the inside of this tube 6, or on it the lower cylindrical element 10 of the housing 11 of the medical syringe (Fig.1 and Fig.3). The housing 11 has a piston 12 and a scale 13 graduated in ml. In a particular embodiment, the housing 11 has an additional scale 14, graduated in drops for ease of use of the drug and prophylactic preparation 1, the dose of which is calculated in drops. In a particular embodiment, the elongated portion of the tube may be monolithic, or elongated by a length of a similar tube 15 (FIG. 1). In the inoperative state, the system is disassembled and the medical syringe, as a component, as well as a component piece of the tube 15, can be packed in a case 16 and sold complete with the preparation 1.

The inventive system operates as follows. Unscrew the lid (not shown in Fig.) Of the reservoir 2 filled with the drug or prophylactic preparation 1. Inside the monolithic tube 6 from the side of the upper surface of the lid 5, the length of which ensures the selection of the preparation 1 from the bottom 9 of the reservoir 2, the lower case element 10 is tightly seated 11 of a medical syringe (not shown in FIG.) And the required dose of the preparation 1 is taken into the body 11 using the piston 12, or higher than this dose in the case of a small dose, controlling selection either on a scale of 13, calibrated in ml, or on a scale of 14, calibrated Noah in drops. The medical syringe is disconnected from the system and the preparation 1 is transferred, for example, to a glass or spoon (not shown in Fig.), Where it is quickly

squeezed, for example, into water. If the dose of drug 1 is exceeded, it is returned to reservoir 2 by lightly pressing the piston 12 down. After use, the medical syringe is washed and stored as a component of the system.

The practical applicability of the claimed system for the exact dosage of a liquid drug shows the following example of a specific implementation. Example.

The liquid solution of the extract of Myrtle "Scythian Gold" is packaged in a tank having a volume of 100 ml, the recommended dose is 20 drops per tablespoon for adults. The height of the tank is 9 cm.

Unscrew the lid of the tank, in the neck of which a plug with a tube is inserted. The length of the lower part of the tube due to its extension by the component pipe segment is 9 cm, which makes it possible to take the drug from the bottom of the tank. Dressed on the upper part of the tube, the outer diameter of which is 1.9 mm, protruding from the upper surface of the cap, the lower cylindrical element of the body of the medical syringe, the inner diameter of which is 2 mm, has an additional scale, graduated in drops. Using a piston, fill the body of the medical syringe to the required level with a liquid solution of the drug and transfer it to a spoon with water, placing the lower cylindrical element under the water level.

The operation of selecting the required dose of the drug is quick. The dose of the drug is selected accurately and has minimal contact with air, the remainder is returned to the tank.

As can be seen from the example, the claimed combination of features provides a solution to the problem and the achievement of such results as increasing

dosing accuracy, eliminating the losses of the dosed liquid preparation, reducing the time for selecting the required dose of the liquid preparation, reducing the contact of the dosed drug or prophylactic drug with air and has wide practical applicability.
