The invention relates to the field of veterinary medicine, in particular for the diagnosis of gynecological diseases in animals, leading to infertility, and can be used in the study of various forms of obstruction of icepronav animals.

The prototype of the invention is a method for the diagnosis of obstruction of icepronav by entering them in the air under positive pressure and is judged on the cross-pressure drop [1].

The disadvantage of this method is the need for pumping air from the vagina through the cervix, which does not allow to control the tightness of this process presents significant difficulties associated with the need for fixation of the animal and the insertion of a catheter into the cervix. In addition, this method does not allow differential diagnosis relative obstruction of icepronav.

The invention allows to obtain a new technical effect - increases the efficiency of diagnosis can help you diagnose not only the absolute but also the relative obstruction icepronav at a pressure below 300 mm RT. Art., simplifies the equipment due to the lack of machine for fixing of animals, and increases the science of studying forms of obstruction. Provide ample opportunities for scientific research, for example during routine slaughter.

This new technical effect is achieved by the fact that aizprua separated from the uterus and is immersed in a container of liquid and air is injected through the funnel alcaravea and judged on the cross output air from the uterine end and the extent of the pressure drop.

The drawing shows a circuit implementing the method.

The method includes immersed in the vessel 1 with fluid aizprua 2 with uterine end 3 and the funnel 4, in which the catheter 5 with hose 6 connected to the syringe 7 and 8 gauge. When this hose 6 from the side of the funnel 4 alcaravea 2 is equipped with a clamp 9. From the side of the syringe 7 between it and the pressure gauge 8 can also be set in the second clip.

The method is as follows. Aizprua 2 is separated from the uterus and is immersed in the vessel 1 with the liquid. When closed, the clamp 9 and open the clamp 10 with a syringe 7 air pumped into the system, the hose 6 and 8 gauge up to 300 mm RT. Art. and put the clamp 10. The pressure in the system is maintained. The catheter 5 is introduced into the funnel 4 alcaravea 2 and immerse aizprua 2 in the vessel 1 with the liquid. Release the clamp 9. When preserved patency of alcaravea 2 system pressure is reduced, which is registered on the pressure gauge 8, and the air bubbles are visible from the uterine end of 3.


To establish the nature of pathological changes in iceproof 2 at the factory examined the body of the reproduction 55 killed cows. 23 animals found signs of pathology icepronav 2: salpingitis in 11 animals, cyst alcaravea 7 cows, connective tissue adhesions in ovarian bag have 2 cows, fusion of the leaves of the mesentery in the field of alcaravea 3 cows.

Using the proposed system was installed pathology not be detected by macroscopic study iceproof, vdova air under pressure up to 300 mm RT. senior Full occlusion icepronav found in 6 animals. Of them one-sided - 5 cows, two-way - 1 cow. Relative obstruction associated with stenosis of the fallopian tubes, diagnosed 5 cows. The maximum pressure applied in alzarooni, was equal to 300 mm RT. Art., patency was maintained until the manometer readings from 160 to 70 mm RT. Art. (table), then the pressure in the system decreased, indicating that partial obstruction.

Type of obstruction icepronavThe number of animals
Unilateral obstruction (complete)5 (9,05%)
Bilateral obstruction (complete)1 (1,81%)
Relative obstruction (one-sided), with complete obstruction in the opposite horn 3 (5,435)

SUBSTANCE: method involves applying computer-aided processing of general plan survey X-ray films with one or several zones of interest being detected on digitalized image corresponding to the number of osteogenesis foci. Quantitative osteogenesis intensity estimate is obtained by applying test grid and interpreting ratio of areas corresponding to distraction regenerate mineralization degree. Boundaries are determined in each zone of interest for delimiting intensity ranges characterizing tissue mineralization degrees at osteogenesis stages and reference points are marked. The first reference point is selected on proximal bone fragment end turned to diastasis. Lower boundary line of the proximal test grid, composed of parallel lines being perpendicular to long bone axis, is superposed with the first reference point. The second one is selected on distal bone fragment end turned to diastasis and the upper line of the distal test grid is superposed with it. Every region belonging to a zone of interest confined by neighboring test grid lines is segmented within the scope of established boundaries into intensity ranges and intensity range area shares in the total area of each region belonging to zone of interest. The intensity range area share proportions are used for estimating osteogenesis intensity.

EFFECT: wide range of functional applications.
