Abstract

Use: for dispensing liquids, for example, small volume liquid medicines. SUMMARY OF THE INVENTION, with the contents of the base container with the shut-off valve open, the tared container is filled to the edges, while the drain cock is closed. After filling the calibrated container, the shut-off valve closes, and the drain valve opens and the metered volume enters the container. In the intervals between several dosing cycles, the overflow receiving and storage tank is emptied into the base container. In order to change the volume, the calibrated different volume rings 1 sludge are lowered into the calibrated tank AAA1 or

The invention relates to the dosage and measurement of the flow rate of liquids, in particular to dispensers of liquid small volume pharmaceutical preparations.

The aim of the invention is to improve the accuracy and manufacturability of a device for measuring, dosing, metering and monitoring small discrete volumes of liquid.

The drawing shows a diagram of the device.

The base tank 1, located on the mounting tripod 2, is connected by an inlet pipe and an adapter 3 with a shut-off valve 4. On the same tripod 2, under the shut-off valve 4, a calibrated tank 5 is located, combined with a container for receiving and storing liquid overflow 6, Inside the calibrated tank 5 are located calibration rings of different sizes 7. The calibration tank 5 is connected through the outlet pipe and adapter 8 to the drain valve 9. In addition, an aiming stop 10 is located on the base of the mounting tripod, to which the filling is adjacent asfasovochna containers 11.

The device operates with the help of the operator as follows.

When the shut-off valve 4 is open, the contents of the base container 1 are filled to the edges with a calibrated container 5. while the drain valve 9 is closed. After filling the calibrated container 5, as evidenced by the flow of liquid overflow into the overflow tank 6, the shut-off valve 4 closes, the drain valve 9 opens and the dosed volume of liquid enters the packaging container 11. The entire dosing cycle is repeated after closing the drain valve 9 and replacing the packaging

In the intervals between several dosing cycles, the overflow 6 receiving and storage tank is emptied directly into the base tank 1 (due to the presence of a spout on the tank 6, it is lossless).

If necessary, change the dosage of the volume of liquid in the calibrated container 5 is lowered or the calibration rings of different sizes 7 are removed from it.

Measurement, control and accounting of fluid flow is carried out by multiplying the tared volume by the number of dosing cycles, after which the result is compared with the remaining liquid in the base tank, on the surface of which measuring marks are applied.

Thus, the technological design of the device makes it possible to accurately measure, dose and take into account small volumes of liquid drugs when they are packaged, for example, in pharmacies.

An important advantage of the proposed device is the low cost and manufacturability of the dosing process, which allows the operator of any skill to work with the device.

Taking into account the urgent need for medical-technical, medical-biological and pharmacological organizations in such medical equipment, it can be argued about the sociological and, therefore, economic efficiency of using the proposed device.
