SUMMARY OF THE INVENTION: the device consists of an elastic container 3, in the lid of which a dispenser is mounted, comprising a feeding tube located in the container and a metering chamber, divided into four measuring compartments connected to the supply tube 10 and having drain tubes 5 oriented adequately to the milk-control mouths records. 2 ill.

Description

The invention relates to the diagnosis of mastitis in cows using liquid diagnostic reagents, in particular to devices for its implementation.

Diagnosis of subclinical mastitis is carried out according to known guidelines for the diagnosis, treatment and prevention of mastitis in cows.

In the milk control plate having four holes (according to the number of quarters of the udder), one ml of milk from each lobe is poured into the corresponding hole and 1 ml of diagnostic reagent is introduced, the mixture is stirred for 10-15 seconds.

An automatic pipette is used to insert the diagnostic reagent into the wells of the milk control plate. It has a dispensing container with drain holes and a tube inserted in the middle to a certain depth and extending in a plug connected to the bulb. In order to fill the pipette, the flask is tilted so that the liquid flows into the pipette through the tube. The flask is then returned to its original position, with the excess liquid draining back into the flask, and a certain amount (in this case 1 ml) remaining in the dosing tank. Then the pipette along with the flask is tilted towards the drain hole through which a measured amount of liquid flows.

The disadvantages of these devices are: the impossibility of simultaneously introducing a diagnostic reagent into the four holes of the milk control plate; prolongation of the diagnostic test, low research efficiency, since the reagent and milk react within 10-15 days, i.e. added reagent to subsequent holes, it is impossible to keep track of the reaction in previous ones; bulkiness of the device.

The aim of the invention is to remedy these disadvantages and to provide a device for the simultaneous dispensing of a liquid diagnostic reagent,

Figure 1 shows a longitudinal section of a device mounted on a plastic bottle; figure 2 - the internal structure of the device.

This goal is achieved by the fact that in the proposed device four chambers with a capacity of 1 ml each are connected to one assembly. The device has a common housing 1, mounted on the cover 2 of a polyethylene bottle 3. The housing has one infusion 4 and four drain pipes S, which depart from the corresponding measurement. Inside, the casing is divided by partitions into four communicating chambers. Camera Post

is carried out at the level of the inner free end of the infusion tube 4, at which level the upper part of the partitions is ground. This allows you to fill in each chamber

exactly 1 ml of diagnostic solution with the device upright. The drainage tubes diverge so that their free ends end at a distance corresponding to the distance between the dimples of the milk control plate. The housing has a cap 7 with a hole and a pipe 8, on which a rubber balloon 9 is worn.

The principle of operation of the device. The polyethylene bottle is filled with a diagnostic reagent. On the outer end of the infusion tube, put on a rubber tube 10 so long that the free end reaches the bottom of the bottle after

strengthening the device on it. A stopper (lid) with a device fixed on it is tightly screwed onto the neck of the bottle. By compressing its walls, the reagent solution is fed into the chambers and filled with them. Surplus

the solution is removed from the chambers, for which purpose the compression of the walls is stopped, which, when straightened, suck out the excess solution from the dispenser chambers, 1 ml of solution remains in each chamber. The bottle is tilted by directing the ends of the drain tubes into the holes of the milk control plate. The solution from the chambers flows into the wells through the drain tubes. The remainder of the reagent is removed from the drain tubes by squeezing a rubber bottle

on the device cover

Using the proposed device allows you to: simultaneously make 1 ml of diagnostic reagent in all four

holes in the milk control plate: to reduce the time for conducting a milk test in the diagnosis of subclinical mastitis: to increase the effectiveness of diagnostic tests; make device

compact.

The results of the production audit showed high efficiency when used to diagnose mastitis by changing the quality of milk.

Claims (1)

The claims A device for dispensing liquid, preferably in the diagnosis of mastitis, consisting of an elastic container in the lid of which a dispenser is mounted, comprising a delivery tube located in the container, a metering chamber and a drain part, characterized in that. that, in order to improve ease of use in the diagnosis of mastitis, using a milk control plate, the dosing the chamber is divided into four measuring compartments, each of which is connected to the supply tube, and the drain part is made in the form of drain tubes fixed to the chamber wall and communicated with the corresponding compartment, while the outlet parts of the drain tubes are oriented adequately to the holes of the milk control plate.
