Abstract

The invention relates to veterinary medicine. The purpose of the invention is to increase operational reliability. The device consists of a metering chamber A, a housing block B and a nozzle C for the introduction of a substance. After the liquid has been drawn from the pressure vessel, the trigger 7 is pressed, while the rotary plate 24 rests on the stoppers of the inlet 2 and outlet 4 of the chambers, moving to the rear position. Fluid through the distribution system enters in C.

Description

The invention relates to veterinary medicine, in particular, to devices for administering similar drugs to animal cavities.

The purpose of the invention is to increase operational reliability.

Fig, 1 shows the proposed arrangement; in fig. 2 - the same view from the side of the switching plate.

The device consists of a metering chamber A, a housing block B and a nozzle C for introducing the substance into the cavity.

Block B includes two input 1 2 and two output 3 and 4 chambers, hose 5, output channel 6, starting device. The triggering device has a trigger and a rod 8. The distribution system with an output channel 9 is made in the form of a chamber, in one of which walls there is a hole with a seal 10. Spring-loaded 11 valve 12 with rods 13 are located in the input and output channels. The fitting 14 is connected to a hose from an external container in which the medicinal fluid is under pressure. Through the connecting channel 15, the liquid enters the inlet chamber.

The dosing chamber includes two plates 17 placed in the handle 16, a double-walled elastic cap 18, in one of the compartments of which a fluid is fed through the channel 19. One compartment 20 is placed in the cavity of another compartment 2 T. The side walls of the handle are movably mounted on three screw guides 22.

The stem 13 of the spring-loaded valve has stoppers 23 at the free end. The fluid supply switch is made in the form of a recessed rotary plate 24. The inlet chambers are connected to the output channels 25 and 26. The outlet chambers are connected to the cavities of the metering device by outlet valve apertures 29-31.

The dose volume is determined by graduation 32 by rotating the screw guides while changing the position of the plates 17.

These elements are functionally combined as follows. The distribution unit includes inlet 1 and 2 and outlet 3 and 4 chambers with spring-loaded valves 12, interconnected by channels 15, 25 and 26, with a metering chamber - channels 19 and 27, with a choke

13 - an inlet channel 9, with a nozzle C - outlet channel 6. The trigger unit includes a trigger 7, a rod 8 and a switching plate 24 which abutting the stoppers 23 24. A dosing chamber located in the handle 16, the side walls 17 of which are movable along screw guides 22 with graduation 32, includes double-wall cap 18, forming a compartment 20, placed in the cavity of another compartment 21.

The device works as follows.

Fluid through the hose comes from an external tank. Pull the trigger 7, the plate rotates against the stoppers.

23 of the valves of the second and fourth chambers and moves with the valves to the rear position. The outlet openings 29 and 30 of the chambers are opened, and the return springs of the rods are compressed. Liquid through the distribution unit enters the internal elastic container 20 of the dosing chamber, pressing its walls and walls of the container 21 against the walls of the handle. After filling the dosing chamber with a dose of the trigger is released and

spring return valves

move to the front position

closing the outlets 29 and 30, and

return the turn plate 24 to its forward position with their stoppers 23.

After turning the plate by notches, under the valve stoppers of chambers 1 and 3, the device is ready for operation.

The nozzle is inserted into the mouth of the animal and the trigger is pulled. Turning

the plate, resting against the valve stops of the chambers 1 and 3, retracts them to the rear position, and the outlet openings 28 and 31 of these chambers open. The fluid through the outlet 28 of the chamber 1 through the chamber 4, the passage through the channel 27 fills the elastic container 21, simultaneously squeezing the liquid from the container 20 through the channel 19 into the chamber 3 and further along the channels 31 and b into the nozzle to the animal.

After the dose is administered, the animal needs to turn the switching plate under the feet of the other pistons, and the device is again ready to work.

Claims (3)
