Definitions
- the invention relates to a device for insemination of
- Vagina which has a bulge in the area of its end to be inserted and an approximately sleeve-shaped hollow body that can be inserted at the beginning of the vagina, through which the bulge and catheter m can insert the vagina.
- the catheter which essentially consists of a relatively stiff plastic tube, m at its end m a bead that is to prevent the flow of semen back during insemination.
- a hollow body preferably in the form of a sleeve, is provided, which surrounds the bead and the catheter and which is penetrated through the vagina when the catheter is inserted, so that there is an improvement over infectious contamination, as described in the description of the aforementioned prior art.
- a device of the type mentioned at the outset which is characterized in that the bead is made of a foam plastic or the like and can be compressed before being inserted into the vagina to a cross-section that falls below the lumen of the vagina when the end position corresponding to the cervix of the animal is reached after an expansion time, it expands so far that the uterus is closed with a soft, retractable plug.
- the bead is preferably toroidal or cylindrical-sleeve-shaped and attached to the end of the catheter to be inserted. An additional air flow is not necessary.
- a corresponding plastic foam mass can be set so that after the compression, which can happen, for example, manually or through the outer wall of the hollow body, there is sufficient time until the bead has stretched again so that it of the vagina.
- the material used - foam plastic - is so soft that it can be easily withdrawn from the vagina without causing injuries.
- the end of the catheter have an outward thickening on which the bead is supported.
- a second thickening can see superiors be that, as a bead length in a corresponding ⁇ the distance is disposed from the first thickening.
- the outside diameter of the thickening is dimensioned in such a way that it falls below the lumen of the vagina and therefore cannot cause injuries.
- Suitable for the material of the bead are soft, elastic foam plastics which are compressible and which, after being released, expand and stretch again in a certain time, for example within 10 to 30 seconds, and return to their original shape.
- polyurethane foam plastics have this property.
- soft foams according to DIN 7726 are used, which have a relatively low resistance to deformation when subjected to pressure. The slow retardation can be adjusted with the aid of plasticizers and recipes known to the person skilled in the art.
- the compression and maintenance of the compressed bead before the actual insemination can be achieved in different ways.
- a tearable film sleeve can be used.
- the released bead expands to its original shape, being within a certain time sufficient for the catheter tip reached the cervix, the shape is restored.
- the bead can be smooth-cylindrical on the outside according to the needs and taking production costs into account; but it is also possible to provide it in the form of a spiral or with lamellar interruptions, so that it has an annular or spiral-shaped, peripheral recess on its outside.
- a kink or a return valve is provided on the catheter, which is arranged at its end opposite the bead
- the hollow body surrounding the bead before the start of insemination and protecting it from infectious contamination remains at the beginning of the vagina after insertion, while the end of the catheter provided with the bead can be displaced in the direction of the uterus and can be pushed out of the hollow body.
- the hollow body can be “two-stage, i.e. be divided into two chambers, of which a first chamber serves to receive the non-compressed bead.
- the expanded bead is not compressed during storage and is protected from damage.
- the smaller, second chamber in turn serves to receive the compressed bead.
- FIG. 1 shows an axial half section of the device, with a bead inserted into the hollow body
- FIG. 2 shows an insemination device with a bead which has the peripheral recesses and is shown compressed and released
- 5a shows another embodiment of the device, in axial section
- FIG. 5b shows an enlarged detail of a return valve
- FIG. 6 an artificial insemination of a sow using the device according to the invention
- FIG. 1 shows a device 100 for the artificial insemination of sows, which is composed of a catheter 1 and a sleeve-shaped bead 2.1 inserted into a tube end 1.1 of the catheter.
- the end 1.1 of the catheter has an outwardly directed, conical thickening 4.1 on which the bead 2.1 attached to the catheter is supported.
- a second thickening 4.2 is also attached to the catheter 1, which is arranged at a distance A from the first thickening 4.1 corresponding approximately to a bead length L.
- the axial position of the bead 2.1 relative to the catheter is thus determined by the arrangement of the two thickenings 4.1, 4.2.
- the beads 2.2, 2.3 and 2.4 are placed on the catheter 1.
- the catheter 1 with bulge 2.1, 2.2, 2.3.2.4 is Emweg device designed.
- the beads 2.1, 2.2, 2.3, 2.4 can also be used as interchangeable Emweg elements.
- FIG. 2 shows a similar (reference number 200) device in which the exchangeable bead 2.2 has a plurality of peripheral recesses 3.1. As the upper part of the figure shows, the previously compressed bead 2.2 assumes a substantially enlarged volume and changes into a plug 20, which can also be seen in FIG. 6.
- FIGS. 3 and 4 show other embodiments (reference numbers 2.3, 2.4) of the bead in which the expanded bead (grafting) has rounded portions 9 or bevels 11 so that the catheter tip can be guided more easily and the animal is not injured.
- the bead shown in FIG. 3 has a single, spiral recess 3.2.
- the bulge 2.1, 2.2, 2.3, 2.4 is made of a soft, closed-cell polyethylene or polyurethane with a density of approximately 40 kg / m 3 , with the aid of plasticizers and other additives the recovery time of the foam being adjusted so that the plug is so compressible that the cross section falls below the lumen of the vagina.
- the end of the expansion time is awaited within the end position, the plug expanding to such an extent that the vagina is closed with a soft, retractable plug 20.
- the expansion time can be set according to the temperature of the vagina and the size, according to professional judgment with appropriate plastic cores.
- the hollow body 16 is divided into two chambers, namely a first, larger chamber 25 for receiving the uncompressed bead and a second, smaller chamber for receiving the compressed bead .
- the position of the non-compressed bead in the first chamber 25 is defined by the knobs 33, which are arranged on the inner surface of the cylindrical part (chamber 25) and which fit into the peripheral recesses 3.1 of the bead.
- the hollow body 16 is gently tapered in a transition region 27 from the first to the second chamber.
- an opening 32 can also be seen in the jacket of the hollow body 16, through which a liquid lubricant can be introduced into the interior of the hollow body by means of a pipette (not shown).
- annular disk 28, 28.1 made of plastic is provided, which is supported either on the tapered part (transition region 27) of the hollow body 16 or on its collar 34.
- the correspondingly disinfected washer 28, 28.1 which serves as a stop element during insemination, can be used several times.
- the pubic area 21 (cf. FIG. 6) is to be cleaned very intensively. Then the bead and the exterior of the hollow body are treated with paraffin oil and made to slide. Other lubricants should not be used as they can damage the sperm.
- the device as shown in FIG. 1, with the hollow body 6 inserted into the vagina 31 ahead.
- the hollow body 6 can be inserted into the sheath 31 until its collar 6.1 or ring disk 28, 28.1 (cf. FIG. 5a) projecting outwards lies on the outer pubic area.
- the thickening 4.1 abuts a truncated cone 6.2 of the hollow body 6 and opens its thin-film closures 6.3 and allows the bead to pass.
- the initially compressed bulge expands within about 20 seconds, takes on its largest volume and closes the vagina in the direction of the cervix so that the sperm cannot flow back.
- a kink 12 is provided at its end 1.2 opposite the bead. By simply kinking the catheter 1 and clamping it with a clip, clip closure or the like. it is achieved that this remains closed immediately after insemination.
- the catheter 1 has a return valve 13 attached to its end 1.2 opposite the bead.
- the return valve 13 is designed in the form of an elongated, elastic sleeve 13.1, which has a thin-skinned, membrane-like, likewise elastic blocking member 23.
- the blocking member 23 is pierced.
- the elastic blocking member 23 closes and prevents the semen from flowing back.
- the return valve 13 can of course be used in all of the described embodiments of the device.
- the sow must "hold” the device, ie there must be slight resistance when the bead is withdrawn.
- the experienced keeper knows which one Point the catheter unit has to guide.
- a seed container 18 (see FIG. 6) is then connected to the end. By slight pressure on the container 18 it is ensured that the sperm m the uterus 41 can flow.
- the entire time of insemination should last at least 3 minutes. The sow is stimulated during and after insemination.
- the catheter tip After emptying the semen container 18, the catheter tip should not be withdrawn immediately. This avoids unnecessary sperm return. If a certain time has expired, the catheter 1 with the bead and at the same time the hollow body 6 are also removed.
