(57) Abstract:

The invention relates to the field of veterinary obstetrics, in particular to tools for administration of medicinal solution in the tank of the affected part of the udder of cows. The syringe consists of a cylinder with a piston with a cross-shaped rod, cannula, made in the wall at the bottom of the cylinder at an angle close to straight. The side edges of the cross rod have the grooves for installation of the metering plug. The kit syringe included hose on the ends with a needle, one of them with a petal. The design ensures easy operation. 1 C.p. f-crystals, 4 Il.

The invention relates to the field of veterinary obstetrics, particularly to instruments used for the treatment of mastitis in cows by introducing the medicinal solution in the tank of the affected part of the udder.

To do this, use the syringes of various designs. D. K. Worms, A. N. Tarasova. Pharmacology with the recipe. M "Kolos", 1981., S. 80.

The closest technical solution is a syringe "Record" according to GOST 18137-77 representing a cylinder with a cannula in the center of the bottom and the piston rod. While the dose of an administered drug is determined by the labels put on the cylinder or POM is in the tank the affected part of the udder with a syringe "Record" according to GOST 18137-77 with one hand hold the teats of the udder, and in the palm of the other syringe, taking him closer to kanuka thumb and forefinger, and tightly combine the openings of the channels of the nipple and the cannula of the syringe (sometimes use a catheter or an end portion of the cannula of the syringe is injected into the channel of the nipple). Then the fingers of the hand holding the nipple and hold the syringe and the other hand to catch it to put pressure on the piston.

The disadvantage of this syringe is the inconvenience of its use for administration of medicinal solution into the cistern of the udder with mastitis, as:

1. After combining the channels of the nipple and the tip of the syringe or injection into the teat of the udder end portion of the cannula (catheter), you need one hand to hold the nipple and the syringe in a fixed position. When you move a small cow overlapping channels nipple and cannula of the syringe is broken, and the use of the catheter, he jumps out of the nipple. Have manipulation to repeat.

2. Catching syringe hand to push on the piston, extends the procedure that must be done as quickly, so as not to disturb a sick animal.

3. It is impossible to maintain sterility remaining in the syringe medication after partial use.

Declare technical mastitis.

The technical result is achieved by the fact that the syringe having a cylinder, a piston with a cross-shaped rod, the cannula is made in the wall at the bottom of the cylinder at an angle close to direct, and at the lateral edges of the cross rod made the slots for the installation of the metering plug, retainer podpornoy volume (dose). The kit syringe included hose on the ends with needle - one of them with a petal.

In Fig. 1 shows a General view of the syringe in longitudinal section; Fig. 2-coupling, General view; Fig. 3 - plug the dispenser; Fig. 4 - hose.

The syringe includes a cylinder 1 with a flat bottom, closer to him in the wall has a hole, which begins the channel of the cannula 2 is angled close to a direct relative to the wall. With the outer surface of the cannula made the thread 3, and the end cone.

The piston has a circumferential groove 4 for sealing rings 5. On the edges of the plates forming the cross-shaped rod, the grooves 6, they are indicated by numbers printed on the plane. On the upper end of the rod is made push Playground 7.

Plug-dispenser has two branches, forming at the junction of the plate 8. The cap 9 cone, hollow.

Coupling one end has an internal thread, a friend of the th thread.

The kit syringe included hose on the ends with needle: one extended, the other skinny with petal 10.

The use of the syringe as follows. Syringe fill out a medical solution, the cannula recap, which strengthen the coupling Navitel it on the threads of the cannula. Plug dispenser is inserted into the grooves located closer to the edge of the cylinder. As such, the syringe is to be transported.

Before the introduction of the medicinal solution teats of the udder treated with iodinated alcohol. Determine the dose needed for treatment. Rearrange plug dispenser, it is set in the slots marked with a number corresponding to the dose. Turn the clutch, with the cannula of the syringe, remove the cap and put on extended cannula hose that fits into the slot on the clutch, which tightly twist.

The syringe is held in the right hand, with the bottom of the cylinder rests on the palm and the middle, ring fingers and little finger hold for a push pad. Thumb and forefinger hold the free end of the hose. The other hand take teats of the udder and combine channels nipple and tip on the end of the hose. Immediately after combining the channels exert pressure on a pressure pad fingers, cateringzalie cow.

After the introduction of the medicinal solution Unscrew the clutch, remove the hose, put on her cap and re-spin coupling. So keep the remaining in the syringe of the drug.

1. The syringe containing the cylinder with the cannula and the plunger with a cross-shaped core, wherein the cannula is made in the wall at the bottom of the cylinder at an angle close to straight, and the side edges of the rod are made grooves for installing plug-dosing.

2. The syringe under item 1, characterized in that it is additionally equipped with a hose with a needle at both ends, one of which with a petal.

SUBSTANCE: the suggested method deals with selecting the samples and their transportation for further testing. Liquid sample should be applied into a sterile syringe due to vacuum through a pipette for recto-cervical insemination in cows. Pipette and a syringe should be connected with a coupling the length of which enables to change the angle of syringe's inclination against a pipette, moreover, a free end of pipette should be applied at an angle in cavitary organ. After selecting the samples on should disconnect the coupling and the pipette against the syringe, and its cannula should be covered with a cap. The present innovation enables to increase the safety of working process while selecting liquid samples out from remote sections of cavitary organs followed by their transportation for further laboratory investigation.

EFFECT: higher efficiency of selection.
