Definitions

  • the invention relates to a device for cattle obstetrics, in the manner of a device that can be supported against the body of the mother animal, with a neck support that comes into contact with the mother animal, a rod on the side facing away from the mother animal with the rod that can be connected to this rod, and a tensioning device that is arranged on the rod Hook for hanging leg slings for the young animal.
  • the invention is based on a prior art, as is known from DE-C-1 133076.
  • the device shown there has a neck support, which finds its abutment on the mother animal.
  • the neck support consists essentially of a curved hard rubber part or the like and has a hemispherical elevation on its surface to be turned towards the mother animal.
  • the hard rubber part itself is attached to a metal tube, which has a tubular extension piece transversely to it, with which it can be attached rigidly to the rod.
  • the neck support is placed just below the vagina, regardless of whether the mother animal is standing or lying.
  • the entire device is placed in a gentle slope.
  • the spherical elevation in the middle of the hard rubber part of the neck support makes it possible to insert the device into the lower part of the pelvic cavity of the mother animal without the neck support slipping down.
  • the design of the neck support as well as the connection between the neck support and the rod according to the known script harbors considerable risks of injury for the mother animal, in particular if the animal lies on the floor during the birth process. For example, one strives for the largest possible contact surface of the neck support on the mother animal. If the mother animal lies on the floor, it may well happen that the corresponding end of the neck support lies on the floor and therefore the spherical elevation of the neck support cannot be used in the lower part of the animal's pelvic cavity. However, this is an essential prerequisite for the actuation of the clamping device attached to the rod. Without this requirement, the mother animal would be at considerable risk of injury.
  • a device of the type mentioned is also known from FR-A-635 021. This differs from the device according to DE-C-1 133 076 essentially only in the U-shaped design of the neck support.
  • the free legs of the neck support are provided with recesses, with a holding belt being guided through the recesses, which comes to rest on the back of the mother animal when the device is used for cattle obstetrics and thus prevents the neck support from slipping down with the rod. Due to the corresponding design, this device has the same disadvantages as the device according to DE-C-1 133076.
  • the latter device has the disadvantage that it is much too cumbersome to handle and is therefore hardly usable as an effective device for obstetrical cattle.
  • the device consists of a large number of individual parts, i.e. a trolley, two poles, the intricately designed neck support, which inevitably means that the device is heavy and therefore difficult to handle.
  • the two rods require more space due to their spaced arrangement.
  • care must be taken to ensure that the devices used do not take up much space, so that the neck support can be attached to the animal in a wide variety of positions.
  • the freely pivotable neck support makes it difficult to attach the device.
  • the shoulder support is mounted at one end of the rod so that it can pivot about the longitudinal axis of the shoulder support, the shoulder support parallel to the latter Longitudinal axis a bolt mounted in the neck support and the rod perpendicular to its longitudinal axis has a bore and the bolt of the neck support passes through the bore of the rod and the rod engages in a position perpendicular to the contact surface coming into contact with the mother animal in the neck support.
  • the non-rigid connection of the neck support and the rod ensures that the neck support of the device according to the invention for cattle obstetrics can always be inserted into the defined position in the lower part of the pelvic cavity of the mother animal. It is only in this position that pelvic problems can be avoided during the course of the birth.
  • the obstetrician is able to pivot the rod towards the neck support in such a way that it is easy to work during the birth process. Since the rod can only be pivoted about an axis with respect to the neck support, it is ensured that the rod is guided in a defined manner through the neck support and thus the obstetrician does not have to pay particular attention to the position or the guidance of the rod.
  • the rod engages in the neck support in a position perpendicular to the contact surface that comes into contact with the mother animal, the device is easy to use. If pivoting the rod to achieve an optimal working position is superfluous, the rod remains in the locked position and is only pivoted out of this position if necessary.
  • the shoulder support has a latching element facing the corresponding end of the rod in the form of a ball which can be displaced against the force of a spring. Without the introduction of a moment, there is a firm connection between the rod and the neck support in the locked position. As a result, the device is easier to handle, for example when pivoting the rod to achieve an optimal working position is unnecessary or when the device is to be placed on the mother animal. In this case, folding the neck support relative to the rod would be a hindrance.
  • the rod can be pivoted through an angle of 30 ° from the locked position. This angle corresponds approximately to a position of the rod, which is necessary to ensure safe actuation of the clamping device even when the mother animal is lying on the ground.
  • a larger angle would mean that in the case of tensioned leg loops, due to their pull angle, the obstetrician would have to apply too much force to hold the bar. In addition, the risk of the neck support slipping off the mother animal would be great.
  • a special embodiment of the invention provides that the shoulder support has, in addition to the end faces, provided with a spacer against the force of springs, but arranged in a rotationally fixed manner, which have tongues at their ends facing away from the shoulder support for contact with the side surfaces of the mother animal.
  • the arrangement mentioned makes it possible to make the neck support relatively short in its longitudinal extension, the h-ice not reaching over the side surfaces of the mother animal. In this way, even if the mother animal lies on the floor during the birth process, the end of the neck support facing the floor cannot lie on the floor. Moving the neck support is thus excluded, the risk of injury to the mother animal is significantly reduced.
  • the spacers with the tongues which can be moved outwards against the force of springs, ensure that the desired position of the neck support is maintained. This even if forces are introduced through the rod into the shoulder support in its longitudinal direction.
  • the tongues take up holding straps at their free ends.
  • the holding straps pass through corresponding recesses in the tongues and are guided over the back of the mother animal.
  • Fig. 1 shows a top view of the device according to the invention for cattle obstetrics, partly in section and
  • Fig. 2 is a side view.
  • the device for cattle obstetrics consists essentially of the neck support 1, which can be supported against the body of the mother animal, the rod 2 connected to this on the side of the neck support facing away from the mother animal, and the clamping device 3 arranged on the rod 2 with the two hooks 4 Attach leg slings, not shown, for the young animal.
  • the handle 5 on the end of the rod 2 facing away from the neck support 1 and the handle 6 of the tensioning device 3 serve to hold the device.
  • the tensioning device 3 as such is not essential to the invention and is therefore not described.
  • the surface of the neck support 1 facing the mother animal is designed as a blunt wedge.
  • the resulting in the middle of the neck support 1 due to the wedge shape serves the purpose of being able to use the device in a defined manner in the lower part of the pelvic cavity of the mother animal.
  • the neck support 1 as such consists of a receiving part 7 designed in accordance with the overall shape of the neck support 1, which in the area of the the mother animal facing surface and on its end faces has a casing 8 made of hard rubber.
  • the surface of the casing 8 facing the mother animal is characterized by a corrugated surface. This is to prevent the neck support 1 from sliding down on the mother animal.
  • the surface of the neck support 1 facing away from the mother animal has a recess 9 in the middle thereof.
  • the recess 9 is delimited on its sides by four ribs 10, two of which are shown in FIG. 1.
  • the other two ribs are perpendicular to the first ribs and connect them.
  • the ribs 10 visible in FIG. 1 each have a bore 11.
  • a bolt 12 inserted through this bore 11 and secured with the aid of a split pin 13 penetrates a corresponding bore of the rod 2.
  • the receiving part 7 has a locking device 14 in the region of the elevation. This consists of a ball 16 provided with a bore 15, which engages through the action of a spring 17 supported on the bottom of the receiving part 7 in a corresponding recess 18 of the end of the rod 2 facing the neck support 1.
  • the locked position of the rod 2 is shown in the figures.
  • the distance between the two ribs 10 (not shown in FIG. 1) is dimensioned such that the rod 2 can be pivoted in the recess 9 up to an approximate angle of 30 ° in each case from the locked position.
  • a perforated plate 19 pressed into the recess 9 prevents the ball 16 from being pushed too far away from the bottom of the receiving part 7 by the spring 17.
  • recesses 20 On the end faces of the neck support 1 there are recesses 20 with a square cross section. These are penetrated by spacers 22 with a corresponding cross section. A non-rotatable connection is thus created between the recesses 20 and the spacers 22.
  • the spacers 22 have tongues 23 arranged perpendicularly to them, which are used for contact with the side surfaces of the mother animal. At the free ends of the tongues 23, recesses 24 are arranged, which receive tether straps 25.
  • the neck support 1 has only such a longitudinal extent, in other words only such a contact surface as is necessary for the safe handling of the device.
  • the additional lateral guidance of the shoulder support 1 takes place via the tongues 23 with the spacers 22.
  • the spacers 22 have stops 27 secured with split pins 26, between which springs 21 are located.
  • the spacers 22 are in the position shown in FIG. 1.
  • the spring-loaded spacers 22 enable the device according to the invention to be used with animals of different widths.
