Description

The invention relates to veterinary medicine, in particular to devices for the administration of tablets.

The purpose of the invention is to simplify the design.

Figure 1 shows the proposed device, a longitudinal section; figure 2 is the same front view; on fig.Z - store.

The device, made in the form of a gun, consists of a housing 1, a cartridge 2, a magazine 3, a pusher 4, a spring-loaded latch 5 with an emphasis in the form of a hemisphere, a hollow needle 6, connecting earrings 7 and 8, a rocker arm 9, a return spring 10, a pressure lever 11 , a support spring 12, a collet clip 13, channels 14 for tablets, the axis 15 of the drum, the groove 16, the longitudinal slot 17, the axis 18 of the rocker arm.

The device operates as follows. ''

In the channels 14 of the store 3 lay tablets. Then the store 3 through the chute 16 is introduced into the cassette 2 and hemispherical focus of the latch 5, held by the support spring 12, fix it in a predetermined position. The magazine 3 is moved on the axis 15 in the longitudinal slot 17 to position a or b, which makes it possible, rotating the magazine, sequentially, first from one row of concentrically arranged channels 14, then from the other to push the tablets with the pusher 4 into the cavity of the needle 6.

Under the action of the return spring 10, the pusher 4 is maximally retracted and its front end is in the body of the hemispherical stop of the lock 5, which makes it possible to rotate the magazine 3 around the axis 15 to align the tablet with the cavity of the needle 6.

To push the tablet into the cavity of the needle 6, press the lever 11, while 5 the rocker 9 rotates around its axis 18 and the pusher 4, making a translational movement, passing through the body of the retainer 5, pushes the tablet from the channel 14 of the store 3 into the cavity of the needle 6,

To push the next tablet from the channel 14 into the strip of needles 6, release the pressure lever 11, turn the magazine 3 to one fixed position and press the pressure lever 11, pushing the tablet into the cavity of the needle 6.
