Definitions

  • the invention relates to an insemination catheter for animals, in particular for pigs, with an elongated, flexurally elastic Injection tube, which is at its anterior, in the uterus of the Animal insertable end with a soft elastic guide plug is provided.
  • the invention is also based on a method directed to the manufacture of such a catheter.
  • Such catheters are used for artificial insemination of domestic animals, used for example by pigs.
  • the soft elastic Guide plug is used when inserting the catheter Avoid injury to the uterus safely.
  • the elongated Injection tube through which after insertion of the catheter The semen is injected, but must be flexible should have a minimum bending stiffness, however ensures that the tube cannot kink when inserted, so that it is ensured that the catheter with its front Insertable deep enough into the animal's uterus and also for the seminal fluid to be injected remains.
  • a flexible polyurethane foam has become the material for the guide plug proven to be particularly advantageous in meeting the requirements in terms of hygiene, dimensional stability with simultaneous Compliancy and processability to the different, required Forms of grafting perfectly fulfilled.
  • the object of the invention is to provide an insemination catheter to create the type mentioned, with a secure connection between injection tube and guide plug without additional Adhesives or the like is ensured.
  • the injection tube mechanically in the connection area to the guide plug is roughened and that the guide plug made of polyurethane foam exists and directly to the injection tube at its mechanically roughened surface is foamed.
  • the injection tube can advantageously be made of polypropylene, of polyethylene or mixtures of the two materials or also from a coextrudate of an inner polypropylene tube and one outer polymer coating.
  • the surface roughness or groove depth after mechanical roughening is the surface of the injection tube preferably between 0.01 and 0.1 mm.
  • the injection tube is preferably in the connection area roughened by grinding, for example with a grindstone, a grinding wheel or the like can. It is also possible to use the mechanically roughened Surface by at least one indentation or groove in the connection area to produce the injection tube or such Turning or grooving in addition to roughening by grinding the To provide pipe surface.
  • the recess or groove creates likewise a depression into which the polyurethane foam foams can create a positive connection between yourself and the injection tube.
  • the injection tube can be inserted into the mold its end region are chemically pretreated, which is appropriate done by a corona treatment, which makes the mechanical already roughened surface oxidized and thus an even larger one Adhesive strength is generated.
  • a corona treatment which makes the mechanical already roughened surface oxidized and thus an even larger one Adhesive strength is generated.
  • the mechanical pretreatment of the injection pipe in the connection area can by grinding, for example with a Grinding wheel or a grindstone happen; alternatively or in addition, the pipe can also in its connection area a recess or groove obtained by means of a suitable Rotary tool can be manufactured.
  • 10 denotes an insemination catheter for Pigs, consisting essentially of an elongated, flexurally elastic Injection tube 11, which at its front, insertable end 12 into the sow's uterus with a soft elastic Guide plug 13 is provided.
  • the injection tube 11 consists of a polypropylene tube 14, one in the connection area 15 to the guide plug 13 has mechanically roughened surface 16.
  • the guide plug 13 consists of a flexible polyurethane foam, the one directly at the front end 12 in the connection area 15 is foamed on the injection tube 11.
  • the mechanically roughened surface 16 excellent adhesion of the Polyurethane plug on the injection tube safely.
  • the average surface roughness or groove depth s of the roughened surface 16 is approximately 0.25 mm in the exemplary embodiment, while the total wall thickness d of the polypropylene tube 14 is approximately 1 mm.
  • the injection pipe 11 is ground with a grindstone or a grinding wheel of suitable grain size.
  • the injection pipe in the connection area can also be provided with a groove (not shown) or indentation which, for example, winds spirally over the length of the connection area around the pipe and, like the mechanically roughened surface, indentations forms, into which the polyurethane foam of the plug can foam and thus creates a kind of positive connection between itself and the injection tube, so that the plug cannot detach even when it absorbs moisture that reaches the connection area.
  • a groove not shown
  • indentation which, for example, winds spirally over the length of the connection area around the pipe and, like the mechanically roughened surface, indentations forms, into which the polyurethane foam of the plug can foam and thus creates a kind of positive connection between itself and the injection tube, so that the plug cannot detach even when it absorbs moisture that reaches the connection area.
  • the invention is not based on that shown and described Embodiment limited, but there are changes and additions without leaving the scope of the invention. So it is possible, for example, instead of the polypropylene tube a pipe made of polyethylene, one made of a polyethylene-polypropylene mixture or one made of a polypropylene coextrudate and to use polyethylene or mixtures thereof.
  • the Guide plugs can also have a shape other than that shown receive.
  • the surface 16 at the end of the tube can next to the mechanical pretreatment also an additional chemical Treatment experience what through corona treatment, through flame treatment or fluorination of the tube can happen.
