Definitions

  • the present invention relates to an improved device for helping with the birth of animals.
  • the birth of four-legged animals with hooves such as cattle, horses, etc. can cause serious difficulties due to the considerable size of the animal to be born compared to the dimensions of the mother animal. If childbirth is difficult, several people must intervene, each gripping one of the hind or forefoot of the animal to be born and pulling on it to a limited extent, and it must also be possible for the individual to act Feet can withdraw independently of each other in a limited way or even two feet at the same time. This is to avoid injury to the animal to be born and to reduce the pain of the mother animal.
  • Some known devices provide for the use of a correspondingly shaped rod which is provided with holders of a more or less anatomical shape for supporting against the mother's body.
  • the means for actuating the pull cords is also difficult to handle; the entire device cannot be used by one person alone without extreme difficulty.
  • the pulling force is always the same and cannot be changed according to the respective conditions.
  • the present invention has therefore set itself the task of realizing a device which is convenient and practical even when used by only one person, so little for both the mother animal and the animal to be born is as annoying as possible and is also not particularly annoying.
  • a purpose of the invention is also to implement the device at a modest cost with secure positioning.
  • Another purpose is to regulate the forces to be exerted on the feet of the animal to be born.
  • a device which consists of an appropriately profiled rod, which ends with a holder for supporting against the mother animal body and has at least one rack on the opposite longitudinal sides and is also provided with a support holder on which at least one anatomical element is articulated, wherein the position of the anatomical support surface can be changed according to the body of the mother animal when using the device.
  • anatomical support surface has at least one downward, rocking surface, which can take the most comfortable position both for the animal and for the person assisting the birth and handling the device.
  • two anatomical support elements are provided, which are articulated independently of one another on the holder and whose mutual distance can be varied.
  • One improvement provides that the holder of the anatomical element and the rod are articulated in such a way that they can perform a full-angle rotation with respect to one another.
  • each runner is provided with at least one connecting element, which has at least one hooking element, in order to hook into a toothed rack provided on the rod.
  • One variant provides that the hooking element is stretched elastically against the rack.
  • a preferred solution provides that the rotor is connected to the end of an actuating lever that exerts the tensile force.
  • a preferred implementation provides that, in accordance with the pin, the lever end has a shaped opening in order to allow a slightly oscillating movement of the lever parallel to the rod when the runners have to be moved alternately along the rack.
  • a special embodiment provides that the actuating lever can be extended, for example pushed together, in order to differentiate the tensile force due to the change in the tensile force moment exerted by the person assisting the birth.
  • This arrangement can be particularly useful if the animal has a particularly large chest and runs the risk of being pressed in the mother's body and could suffer damage as a result.
  • a preferred implementation provides that the rod has a guide groove, on the sides of which two toothed racks for hooking up one of the runners are arranged.
  • a special implementation provides that the engagement groove has the shape of an inverted T for each rotor, the profile of the rotor being form-fitting.
  • a special solution provides that to release the hooking end from the seat of the rack, the hooking element cooperates with a cam which is arranged on an externally projecting element and is optionally displaceable, and to counteract the actuation of the elastic element mentioned above.
  • This element protruding outside also serves in particular as a handle for moving the runners along the rod.
  • FIGS. 1 to 6 A first implementation is shown in FIGS. 1 to 6.
  • the device designated by 10 consists of a rod 11 with two opposite longitudinal sides, each of which is provided with a toothed rack.
  • the two toothed racks, with each of which a rotor connects, are denoted by 12a and 12b.
  • the device ends with a support bracket 13 for the body of the mother animal.
  • anatomical elements 14a and 14b are attached to this support holder 13. Since the two anatomical elements 14a and 14b are the same, only the anatomical element 14a articulated in FIG. 15a is described for the sake of simplicity, while the same parts of the anatomical element 14b are given the same reference numbers but with the addition b.
  • the holder 13 has different openings 16 which enable the anatomical element 14a to be fastened in different positions, as a result of which the mutual spacing of these elements can be regulated.
  • the anatomical element 14a has an anatomical surface 5a for supporting against the mother animal, while the other opposite surface 17a is curved slightly downwards, as a result of which the element can oscillate and adapt to the position of the mother animal body. This will make it easier for people to assist.
  • the fastener that enables rocking can be of a known type be. A non-limiting example is shown in section in FIG. 2. In this case, the pin 18 is used, which is connected both to the anatomical element 14b and to the holder 13 and has a nut 20 at one end and a screw head 21 at the other end; however, any other known system can be used.
  • the holder for the anatomical elements is rotatably mounted on the rod, which is shown in particular in FIG. 1, where the holder 13 is articulated on the rod with a screw 25 in such a way that a complete rotation of 360 ° is possible.
  • Fig. 3 shows that each side for connection to the rotor has guide grooves 24a and 24b in the form of an inverted T.
  • the runners 30a and 30b shown in FIGS. 1 and 4 and in perspective in FIG. 5 slide in each groove.
  • the rotor 30a is described below, since the same elements of the rotor 30b have the same shape and only the slope is changed.
  • the rotor has a surface 31a (FIG. 5), also in the form of an inverted T.
  • the runner has a hook element 34a for attaching a knitting end (not shown) while the other end of the knitting is attached to one leg of the animal to be born.
  • 35a the fork element 36a is articulated, the two toothed ends 37a of which are each in a rack 12a on both
  • the fork 36a is actuated by an elastic element 38a, which is supported against the protruding element 48a, which forms a release button for the toothed ends 37a of the fork.
  • the grooved rod of special design is particularly advantageous in accordance with each engagement side with the runner, since the profiled end is form-fitting with the groove of the rod so that the runner can slide in the latter. This also results in an extremely easy and economical implementation.
  • any other shape can be provided for the guide groove, provided that the profile of the rotor is form-fitting in order to slide in the groove.
  • the actuating lever 41 is articulated on the two runners 30a and .30b by an annular end 49 on the two pins arranged on each side of the blocks 40a and 40b. This articulation is shown in particular in FIG. 5, which, however, only shows the runner 30a for better clarification.
  • One of the inlet openings (in this solution 39b) is designed as an elongated hole and the other opening 39a is designed as a circular hole.
  • the lever 41 can also be articulated in accordance with the pins 35a and 35b.
  • the actuating lever 41 fixed on the handle 42 can be pushed together so that its length and consequently the force arm used by the person assisting in childbirth can be changed.
  • a special achievement of the collapsible lever is shown in Figures 1 and 6, which show an outer member 46 which is fixedly connected to the handle 42, in which an inner member 44 slides. An elastic element 88 is arranged between these elements. Seats 45 are provided in the inner element, so that the elastic element can expand between them and thus block the lever in the desired position. In this way, the length and the traction arm can be regulated.
  • Another handle 50 is slidably mounted on the rod so that it can be brought into the desired position.
  • the handle 50 has an end 51 for engagement in one of the grooves 24, which is shown in particular in FIG. 3.
  • the end of the handle 50 has a stop surface 50a which abuts against the stop surface 43 of the block 40a. In this way, when the rotor is moved from right to left, the handle 50 is also moved to the left without further intervention.
  • the group of the two runners 30a and 30b is brought in an approximate position to the support holder 13, which adapts well to the mother animal body in view of the presence of the anatomical elements.
  • the slider is shifted to the right after the corresponding toothed ends 37a and 37b are disengaged and the projecting element 48a and 48b, which counteracts the elastic element 38a and 38b, is pressed down.
  • the holder is then supported with the two anatomical elements against the body of the mother animal and the ends of the ropes are fastened to the feet of the animal to be born, depending on the position of the animal to be born, both the front and the rear feet can be.
  • the block 40a rotates around the pin and causes the rotor 30a to be shifted to the left.
  • the pin is supported in accordance with the block 40b against the end of the opening 39b, as a result of which a stop for this movement is formed.
  • both runners can be moved to the right for any run while loosening the ropes.
  • the pulling force exerted can also be changed by shortening or lengthening the length of the lever 41.
  • the tensile moment exerted changes in this way.
  • the rod 61 shown here has a different profile than the embodiment described above, which is shown in FIG. 8.
  • the runners 60a and 60b are also realized in different ways, while the support holder 13, the collapsible lever 41 and the means for performing a complete rotation of the holder 13 relative to the rod 61 are designed in the same way as the parts already described.
  • the rod 61 has a rack 62a and 62b for each rotor 60a and 60b. In this case too, only the rotor 60a is described.
  • the runner 60a consists of a channel-shaped element 66a which has a hook element 67a directed towards the holder 13 for fastening a rope (not shown).
  • 68a a pawl 69a is articulated, which at the end has a tooth 71a which engages in the rack 62a, so that displacement is only possible in one direction.
  • the pawl is held on the rack by a leaf spring.
  • the bar slides in the rotor, while in the previously preferred embodiment, which is readily preferred, the bar is much easier to slide in the grooves specially provided on the bar.
  • the release means for displacing the rotors 60a and 60b to the holder 13 is particularly interesting. It consists of a cam element 73a which is articulated in 74a and connected to the side handle (only the handle 75b is shown in FIGS. 7 and 9). If the tooth 71a is to be released from the rack, the handle 75a must be rotated so that the cam element 73a rotates at the same time and counteracts the spring 70a. The handle 75a also enables the runners to be guided manually to the position where the rack 62a is to be blocked again. In this case too, the shift is gradually made to the left by pivoting the actuating lever 41 to the right and left in the same way as already described.
