Definitions
- the present invention relates to reservoir tubes adapted to contain animal semen and intended for artificial insemination, and more particularly catheters for artificial insemination of birds, in particular turkeys.
- catheters are well known; generally made of plastic, their length is around ten centimeters, their outside diameter is around four millimeters and their inside diameter around 3.3 millimeters along the length of the tube, l 'thickness of the tube wall being generally 0.35 millimeter.
- catheters are of course adapted to the morphology of the turkeys; moreover, in the first place, they are intended to be used only once, to avoid any contamination: they are therefore designed so as to contain only one dose of semen; secondly, to simplify handling, the seed is held in place in the tube by capillary action, taking into account the viscosity of the seed; thirdly, they are suitable for filling devices or machines, and emptying devices or guns designed to avoid contact of the hands with the catheters.
- catheters are of course adapted to the morphology of the turkeys; moreover, in the first place, they are intended to be used only once, to avoid any contamination: they are therefore designed so as to contain only one dose of semen; secondly, to simplify handling, the seed is held in place in the tube by capillary action, taking into account the viscosity of the seed; thirdly, they are suitable for filling devices or machines, and emptying devices or guns designed to avoid contact of the hands with the catheters.
- 1,488,345 are shown catheters, one or both ends of which have an inner diameter reduced relative to the outer diameter of the catheter. So far, such catheters are well suited. However, for reasons of economy and therefore profitability, it has been necessary to dilute animal semen more and more to a dilution of two volumes of diluent for one volume of semen, thus reducing the viscosity of the semen to a level close to the viscosity of water; therefore, the retention in place in the catheter of this diluted semen can no longer be ensured by capillary action.
- the present invention aims to solve this problem in a simple, inexpensive way and to propose a new catheter having all the advantages of the old one, thanks to the maintenance of its general dimensions allowing it to be adapted to the morphology in particular of turkeys. , to contain only a single dose of semen, and to be able to be compatible with existing filling and emptying devices, while retaining the semen by capillarity although this is more diluted than in the past.
- the invention is based on the observation that, on the one hand, it is easy to reduce the inside diameter of a plastic tube obtained by extrusion by a value of up to two thirds, or even three quarters.
- a catheter for artificial insemination of birds, in particular turkeys consisting of a plastic tube obtained by extrusion, each end of the tube being shaped so that the inside diameter of the tube at its ends is reduced, is characterized by the fact that the inside diameter of the tube at its ends is reduced to a value between two thirds and three-quarters of the inside diameter of the tube, this reduction can be obtained when cold at exit from the extruder. None of the catheters shown in the documents cited above have these characteristics; they only apply to undiluted seeds.
- the plastic material constituting the tube is polyvinyl chloride.
- Other thermoplastic materials may be suitable, such as, for example, polyethylene terephthalate glycol.
- each of the ends has a hem obtained by turning inward the end portion of each end.
- the outside diameter of the tube is around 4 millimeters and its thickness around 0.35 millimeters.
- the inverted portion of the hem extends inside the tube over a length of between about three and six times the thickness of the tube; the cylindrical wall of the hem which faces the inner wall of the tube is pressed against the latter; alternatively, the cylindrical wall of the hem which faces the internal wall of the tube is at a radial distance from the latter at most equal to seven tenths of the thickness of the tube; advantageously, the cylindrical wall of the hem which faces the interior wall of the tube ends in a frustoconical part widening towards the interior of the tube.
- each of the ends has a generally transverse rim. According to yet another embodiment, each of the ends has a reduced diameter compared to the rest of the tube.
- the present invention also relates to a method of producing a catheter for artificial insemination of turkeys, consisting of a plastic tube; according to the invention, this method is characterized in that the tube is produced by extrusion and each of its ends is cold formed so as to have the characteristics of the above catheter.
- FIG. 1 is a partial sectional view of a catheter according to the invention.
- - Figure 2 is a partial sectional view of one end of the catheter of Figure 1, on a larger scale;
- - Figure 3 is a view similar to Figure 2 and corresponds to a variant;
- - Figure 4 is a view similar to Figure 2 and corresponds to another variant;
- FIG. 5 is a partial sectional view of one end of a variant catheter relative to Figures 1 to 4; - Figure 6 is similar to Figure 5 and corresponds to another variant of catheter.
- FIG. 1 shows in partial section, a catheter according to the invention intended in particular for artificial insemination of turkeys.
- a catheter generally consists of a tube 10 made of plastic material, advantageously of polyvinyl chloride, having a length 20 of the order of 10 centimeters, an outside diameter 21 of the order of 4.1 millimeters, and a thickness 22 of the order of 0.35 millimeters, therefore an internal diameter 23 of the order of 3.4 millimeters.
- the diameter 23 extends over the entire length of the tube, which is then 103.5 millimeters, including its ends 11 which the edges are optionally leveled to avoid injuring the turkeys; such a catheter is well suited for animal semen of a given viscosity, so that it is retained in the tube 10 by simple capillarity; thus, it is not necessary for the transport and / or handling of the catheters to provide a plug at the ends 11 of the tube 10.
- the catheter according to the invention is designed to contain, under the same conditions, a diluted animal semen, the viscosity of which is reduced.
- the ends 1 1 of the tube 10 are shaped so that the internal diameter 24 of the tube 1 0 to the right of its ends 1 1 is reduced by an amount such that said seed is retained by capillarity and the forming of these ends 1 1 is produced in a simple and inexpensive manner.
- the reduction in diameter is such that the outside diameter 24 of the tube 1 0 at its ends 1 1 is reduced to a value between two-thirds and three-quarters of the internal diameter 23 of the tube 1 0 .
- the internal diameter 24 of the ends 11 is of the order of 2.2 to 2.5 millimeters.
- the reduction in diameter is obtained by a simple cold forming operation; the tube 1 0 being obtained by extrusion, the cold forming takes place at the outlet of the extruder.
- each of the ends 1 1 has a hem
- the length 25 of the return forming the hem 1 2 is of the order of three to six times the thickness of the tube 1 0, here therefore from one millimeter to 2 millimeters; it will be appreciated that the production of the hem 1 2 leads to an edge 18 of rounded end, which avoids injuring the animal during the artificial insemination operation; the total length of the catheter is therefore reduced to a value of the order of 1011.5 millimeters; the hems 1 2 of the two ends 1 1 are advantageously produced at the same time, the tube 10 being placed between two corners to be crimped; it will therefore be understood that these two hems 1 2 of the same tube 1 0 may not extend over strictly equal lengths.
- cylindrical wall 1 3 of the hem 1 2 which faces the inner wall 1 4 of the tube 1 0 is close to the latter, see pressed against the latter, extending axially.
- the cylindrical wall 1 3 of the hem 1 2 which faces the inner wall 1 4 of the tube 10 is at a radial distance 26 thereof; this radial distance is small; it is at most equal to 0.25 millimeters; taking into account the viscosity, even diluted, of the seed, it cannot penetrate into the annular space defined by these facing walls
- the cylindrical wall 1 3 of the hem 1 2 which faces the inner wall 1 4 of the tube 1 0 ends in a frustoconical part 1 5 flaring towards the inside of the tube.
- the reduction in internal diameter to the right of the ends 1 1 is obtained by a generally transverse rim 1 6 with rounded edges.
- the body of the tube which has a reduced diameter 1 7 at its ends 1 1; advantageously the edge 1 9 of the ends 1 1 is rounded.
