Definitions
- the invention relates to an insemination catheter for animals, in particular for pigs, with an elongated, flexurally elastic Injection tube, which at its front, in the uterus of the Animal insertable end with a soft elastic Whyspfropfen is provided.
- the invention is further directed to a method directed to the manufacture of such a catheter.
- Such catheters are used for the artificial insemination of useful domestic animals, used for example by pigs, e.g. in document US2106635.
- the soft-elastic Guide plug is used when inserting the catheter To avoid injury to the uterus safely.
- the elongated Injection tube through which after insertion of the catheter the seminal fluid is injected must be flexible be, but it should have a minimum bending stiffness, the ensures that the tube can not bend during insertion, so that it is ensured that the catheter with its front End deep enough into the uterus of the animal is insertable and while also for the injectable seminal fluid throughout remains.
- the material for the guide plug is a soft polyurethane foam proved to be particularly advantageous, the requirements to the hygiene, dimensional stability at the same time Resilience and processability to the various required Forms of grafting perfectly fulfilled.
- the object of the invention is an insemination catheter of the above mentioned type to create a secure connection between injection tube and guide plug without additional Adhesives or the like is ensured.
- the injection tube mechanically in the region of connection to the guide plug roughened and that the NASAspfropfen of polyurethane foam exists and directly to the injection tube at the mechanically roughened surface is foamed.
- the injection tube can be advantageous from polypropylene, polyethylene or mixtures of the two materials or else from a coextrudate of an inner polypropylene tube and a outer polymer coating consist.
- the roughness depth or groove depth is after mechanical roughening the surface of the injection tube preferably between 0.01 and 0.1 mm.
- the injection tube is in the connection area roughened by grinding what with for example a grindstone, a grinding wheel or the like happen can. It is also possible to mechanically roughen Surface by at least one recess or groove in the connection area manufacture of the injection tube or such Grooving or groove in addition to roughening by grinding the Provide pipe surface.
- the recess or groove produced also a depression into which the polyurethane foam lather can be so a positive connection between to create himself and the injection tube.
- Injection tube in addition to the mechanical roughening of his Surface of a chemical pretreatment is subjected to what for example, by corona treatment, by flaming, by etching or fluorination of the front pipe end can happen.
- This chemical pretreatment is preferably carried out after mechanical roughening of the surface.
- an elongated, bending elastic injection tube preferably made Polypropylene, polyethylene or mixtures thereof or even from a coextrudate of polypropylene and a polymer on his one
- a connecting portion forming end first mechanically is roughened and then with his mechanical roughened connection area is introduced into a mold, whereupon a solidifying polyurethane mass in the mold is injected so as to a foamed directly to the injection tube Form guide plug.
- the injection tube before insertion into the mold be chemically pretreated his end, which is appropriate done by a corona treatment, causing the mechanical already roughened surface oxidizes and so an even larger Adhesive strength is generated.
- the treatment of the surface of the pipe by flaming reach or fluorinate or etch the tube.
- the mechanical pretreatment of the injection tube in the connection area can by grinding, for example with a Grinding wheel or a grindstone happen; alternative or additionally, the tube may also be in its connection area a recess or groove obtained by means of a suitable Turning tool can be produced.
- 10 indicates an insemination catheter for Pigs, which consist essentially of an elongated, flexurally elastic Injection tube 11 which, at its front, in the uterus of the sow insertable end 12 with a soft elastic Guide plug 13 is provided.
- the injection tube 11 consists of a polypropylene tube 14, which in the connection region 15 to the guide plug 13 a mechanically roughened surface 16 has.
- the guide plug 13 is made of a flexible polyurethane foam, the directly at the front end 12 in the connection area 15th is foamed at the injection tube 11. It represents the mechanical Roughened surface 16 excellent adhesion of Polyurethane graft on the injection tube safe.
- the average roughness depth or groove depth s of the roughened surface 16 in the exemplary embodiment is approximately 0.25 mm, while the total wall thickness d of the polypropylene tube 14 is approximately 1 mm.
- the injection tube 11 is ground with a grindstone or a grinding wheel of suitable grain size.
- the injection tube in the connection area can also be provided with a groove or recess (not shown) which spirals, for example, over the length of the connection area around the tube and, like the mechanically roughened surface, recesses forms, in 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 can not peel even when he absorbs moisture that reaches into the connection area.
- a groove or recess (not shown) which spirals, for example, over the length of the connection area around the tube and, like the mechanically roughened surface, recesses forms, in 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 can not peel even when he absorbs moisture that reaches into the connection area.
- the invention is not limited to the illustrated and described Embodiment limited. So it is possible, for example, instead of the polypropylene tube a polyethylene tube, one of a polyethylene-polypropylene blend or one made from a polypropylene coextrudate and polyethylene or mixtures thereof. Of the Guiding plug can also be a different shape than the one shown receive.
- the surface 16 at the end portion of the tube may be adjacent the mechanical pretreatment also an additional, chemical Treatment, what by a corona treatment, by Beffämmung or fluorination of the tube can be done.
