Definitions

  • the DEVICE FOR TREATMENT AND PROPHYLAXIS OF MASTITIS IN ANIMALS The supposed invention is related to the field of agriculture, namely to stock-breeding and veterinary.
  • a known device for treatment and prophylaxis of mastitis in animals contains a source of ultrahigh- frequency current and unlike pole electrodes, placed in the intermediate space between the walls of the double- chamber milking cluster [1].
  • the drawback of the known electrodes is that during machine milking the operating mode of the generator changes and so does the power absorbed by the animal tissues, due to the changes of the clearance between the nipples and the electrodes.
  • a known device for treatment and prophylaxis of mastitis in animals contains an ultrahigh-frequency generator and electrodes, connected to unlike poles, each of them is made of two coaxial circular parts in a form of a flat disk removed from each other in axial direction and coupled to each other via an electro-conducting plate [2] (taken as a prototype).
  • the known device has a number of drawbacks, which decrease the efficiency of treatment:
  • the first two drawbacks are interconnected and can be explained in the following way. Due to the fact that the electrodes are placed in the plastic cluster of the milking machine and due to the design of the rubber sucker, the upper circular part of the electrode is not less than 25 mm from the udder (the distance from the upper surface of the sucker to the buff-end of the milking cluster shell) and the inner edge of the circular electrode cannot be more than 3-5 mm away from the surface of the nipple. Besides the dielectric fills the space between the nipple and the electrode more than the space between the main part of the udder and the electrode.
  • UHF energy power flow density going through the nipples is more than an order higher than power flow density in any point of the main part of the udder, and leads to the conditions for overheating of nipples during treatment.
  • the limits of the nipples overheating causes the necessity to limit the UHF energy power absorbed by the udder and the nipples at the level of 15-20 watt.
  • the influence of the UHF field on the centers of mastitis damage of the udder is insufficient if they are situated not in the nipples and not at the base of the nipples.
  • the third drawback can be explained by the fact that during machine milking the operating mode of the generator changes and so does its output power, and as a result the power absorbed by the animal tissues due to the changes of the gap between the body and the electrodes.
  • the aim of the supposed invention is the increase of the radiating energy dosage accuracy and the elimination of the possibility of udder burns.
  • the set aim can be achieved by the fact that in the device for treatment and prophylaxis of mastitis in animals containing a high frequency generator and electrodes connected to its output via a distributing-coordinating unit, are combined with the milking clusters, electrodes are equipped with elastic conducting elements and elements fixing the gap between the animal body and the elastic conducting elements.
  • Elastic conducting elements are made as a system of flexible conductors placed in the intermediate space between the walls of the double-chamber milking cluster, mainly along the forming surface, embracing the nipple rubber.
  • the elements, fixing gap between the animal body and the elastic conducting elements are made in a form of an elastic ring embracing the nipple rubber and the elastic conducting elements.
  • the set aim can also be achieved by the fact that in each electrode the elastic elements are made as two parts of circular coils, wound from a common output in one direction with opposite step, and the winding is made of an elastic spring-based material, and elements fixing the gap between the surface of the animal body and the elastic conducting elements are made as an elastic resilient dielectric shell.
  • the common beginning of the two parts of the circular coils is oriented mainly to the center of the udder.
  • the said design of the electrodes eliminates the opportunity to burn the udder nipples and leads to substantial increase of radiating energy dosage accuracy due to the steady gap between the surface of the animal body in the vacuum pulsation process and steady electromagnetic coupling with the animal body when the nipple rubber is deformed.
  • the input resistance of flat electrodes for example, placed on the body, may be described by an equivalent circuit, containing an active resistor and a condenser connected in series.
  • the size of the clearance between the body and the electrode substantially influences the value of the equivalent circuit capacitance and practically does not influence the value of the active resistance.
  • the suggested electrodes are described by the equivalent circuit containing active resistance, condenser and inductor connected in series.
  • the value of the capacitance between the electrodes and the value of the electrode inductance also change. Moreover, when the value of the capacitance increases, the value of the inductance decreases and vice versa.
  • the choice of the geometric electrode parameters - the coil winding section, the number of coil windings, the conductor section or the equivalent section of the parallely coupled conductors - is made experimentally till minimal changes of the input electrode resistance are obtained, when there are changes of force pressing to the udder and the physiological peculiarities of the udder structure. Thus steady generator load, its output power and radiating power are achieved.
  • Fig.l. is a simplified circuit diagram of a device for treatment and prophylaxis of mastitis in animals in accordance with the invention.
  • Fig.2. is a variant in which an electrode is placed in the intermediate space between the walls of the double- chamber milking cluster (longitudinal section).
  • Fig.3 and 4 show a variant in which the electrode is placed above the surface of a sucker of the milking cluster in axial section and top view accordingly.
  • Fig.5 and 6 show a variant of the device for treatment and prophylaxis of mastitis in animals with electrodes as parts of coils placed above the surface of the milking cluster sucker and the axial section of the electrode.
  • the device for treatment and prophylaxis of mastitis in animals contains a high-frequency generator 1 and four electrodes 3, 4, 5, 6 connected to its output via a distributing-coordinating unit 2, combined with the milking clusters (not shown in Fig.l). Electrodes 3, 4, 5, 6 are equipped with elastic conducting elements 7 and 8 fixing the gap between the surface of the animal body and the elastic conducting elements 7. The elastic conducting elements 7 in each electrode 3, 4, 5, 6 are connected with the inputs of electromagnetic energy 9, 10, 11, 12.
  • the elastic conducting elements are carried out, for example, as a system of flexible conductors 13 placed mainly along the forming surface enveloping nipple rubber 14 evenly on the perimeter of the cross section. Elements fixing the gap between the surface of the animal body and the elastic conducting elements 13 are made as a resilient ring 15 embracing nipple rubber 14 and flexible conductors 13. Elastic conducting elements 13 are connected to the electromagnetic energy input via a common conducting element 17, made, for instance, as a ring or a part of a ring. In variant placing the electrode over the surface of the milking cluster sucker (Fig.
  • elastic conducting elements are also made as flexible conductors 18, placed mainly in the plane coinciding with the forming surface of the nipple rubber 14. Elements fixing the gap between the surface of the animal body and the elastic conducting elements 18, are made as an elastic hollow ring 19, on the inner surface of which elastic conducting elements 18 are placed, connected with the electromagnetic energy input 20 via a conducting element 21, made as a ring or a part of a ring.

  • the device for treatment and prophylaxis of mastitis in animals contains a high-frequency generator 1 and four electrodes 22, 23, 24, 25 connected to its output via a distributing-coordinating unit 2.

  • the ends 31, 32 of the coils 26, 27 may be opened and closed.
  • the elements fixing the gap between the surface of the animal body and the elastic conducting elements are made as an elastic hollow ring 33, with parts of circular coils inside, and placed of the outside surface of the milking cluster sucker 14.
  • the device for treatment and prophylaxis of mastitis in animals works in the following way.
  • the milking clusters having electrodes on and connected to the output of the high-frequency generator, are placed (put) on the nipples of an animal udder.
  • the high- frequency generator When the high- frequency generator is on, electromagnetic field appears between the unlike pole electrodes and affects the udder of the animal.
  • the vacuum pulsation causes the periodic deformation of the nipple rubber 14 and the elements fixing the gap between the surface of the animal body and the elastic conducting elements 7 or 13, 18, 26, 27 ensure constant gap between the elastic conductors and the animal body, to certain instant they "follow" the form of the animal body, that allows to ensure steady electromagnetic connection with the animal body, steady load and output generator power, and, as a result, the accurate dosage of radiated power.
  • Additional generator load stabilization of the device for treatment and prophylaxis of mastitis in animals having as a variant elastic elements of the electrodes as parts of circular coils, is achieved due to the changes of inductance value while the parts of circular coils 26, 27 are deformed.
  • the increase of the electrode deformation leads to the simultaneous capacitance increase between the body and the surfaces of the electrodes, and the value of the electrode inductance decreases .
