Definitions
- the invention relates to an artificial insemination catheter Insemination, in particular of pigs, consisting of a thermoplastic Material of existing catheter tube with longitudinal tube channel, that has a molded body made of soft compressible at its distal end Carries material that surrounds the pipe end and one that continues the pipe channel Molded body channel contains.
- Such insemination catheters are known for example from EP 0 605 406 B1 or the corresponding DE 691 30 835 T2 known.
- the molded body is here a tampon made of soft foam
- the molded body channel in the extension of the pipe channel has a narrowing zone, which has the purpose with a force pressing on the molded body at the front, namely by the pressure of the organs during penetration into the animal's vagina.
- Side effect is that the front edge of the semi-hard material existing pipe is prevented by the pressure applied from behind to move to the front opening of the molded body and then the animal to irritate by scratching and scraping the tissue in an unfavorable sense.
- the constriction of the molding channel proves at the time of desired passage of the liquid as unfavorable, in addition, the The relevant shape is not in the public domain.
- the invention is intended to inseminate a catheter of the type mentioned be further developed in that without the need for a constriction of the canal the emergence of the sharp-edged pipe end is avoided.
- the pipe end in the molded body with projecting beyond the pipe outer diameter, firmly parts sitting on the pipe, in particular integral parts of the pipe the are preferably produced by deforming the pipe end, is anchored.
- a conical widening of the pipe end is possible, however is also a splicing and outward bending of the resulting individual strip-shaped webs possible.
- the corresponding deformations The thermoplastic pipe material can easily be heated when the pipe tip is heated and the material remains when it cools down permanently in the projecting position. That in the pointed process or another molding process applied material of the molded body encloses the protruding parts. Unless it is the foremost parts of the pipe, they cannot be pushed forward in the channel or by pushing back the soft front parts of the molded body finally in its end face get.
- protruding parts consists of, for example shrunk or welded onto the outside of the pipe in the area of the pipe end Ring body, the - right at the end of the tube or something from this moved away - protrudes radially outwards and relative to the pipe in the longitudinal direction is fixed, so that the integral molded body formed around it is also fixed relative to the tube in the longitudinal direction.
- a pig insemination catheter is in accordance with the embodiment of FIG Fig. 1 from an approximately 50 cm long tube 1 made of a relatively rigid thermoplastic Material with a distal end 2, on the enlarged diameter a molded body 3 made of a resilient foam sits.
- the tube has a tube channel 4 and the molded body 3 has a molded body channel 5 on.
- Part of the pipe 1 is seated in the molded-body duct 5, and part, namely beyond the end of the pipe, channel 5 represents the straight-line continuation of the Pipe channel 4 is.
- the Pipe inserted into a mold cavity that has a core for the channel 5 and then introducing foaming material into the mold cavity fills up and sits firmly on the tube 1 inside.
- the tube 1 has a conical widening at its distal end 10, which makes the pipe end funnel-shaped.
- the widening 10 holds completely within the volume of the molded body 3, and the material of the Shaped body 3 rests on the widening 10 on both sides, that is to say still on the inside with an annular lip area 11, which is between the expansion 10 and the Channel 5 is.
- the wall of the channel 5 is in the extension of the Cylinder outer surface of the tube 1, so the channel 5 has a wall thickness of the pipe has a larger radius than the pipe duct 4.
- FIG. 2 is a similar embodiment in a comparable representation shown, but with the wall of the channel 5 in the extension of the inner tube wall lies and the channel 5 has the same diameter as the pipe channel 4.
- the ring lip region 11 turns out somewhat stronger here.
- dashed In Fig. 2 a circumferential bead 12 is drawn in the channel 5, which, if Desired can be formed on the wall of the channel 5 to the channel 5th relatively easy to close by external pressure in a manner known per se.
- FIG. 3 shows a perspective view of the tube 1 with the widening 10 at the distal end 2 according to the embodiments of Fig.n 1 and 2. This Shaping is done by pushing on the pipe end when heated created a suitable cone.
- Fig. 4 shows a different shape of the distal end 2, on which in this case the tube is spliced into a number of strips 15 which are bent outwards and are permanently deformed.
- This claw-like shape is particularly suitable for tube materials that are thinning due to the conical expansion tolerated less.
- the cross section through the end of the catheter can also be look like in Fig. 2.
- Fig. 5 shows the anchoring of the tube 1 in the molded body 3 by a Area of the pipe end on this immovably mounted ring 17, the is melted, for example.
- the Prevents pipe 1 in the molded body 3 is pushing the Prevents pipe 1 in the molded body 3, however, the push back and Fold back the front end of the molded body 3 so that the sharp-edged Tube end comes out, less effectively prevented.
- This version is suitable mainly for constructions with a somewhat firmer molded body 3.
