Insemination cartridge

Technical field

The technical solution concerns an insemination cartridge, which is intended especially for the insemination of sows.

BACKGROUND OF THE INVENTION

The known insemination facilities are solved in different ways. These are both more complex, more versatile devices and simple devices designed for single use.

Simple disposable devices consist essentially of a pouch or container for storing semen and an insemination pipette that attaches to the pouch or container during insemination.

At present, mainly vial-shaped containers made of flexible polymeric material are used, which on one side end with a flat bottom and on the other side have a cylindrical neck. A cap, which has an annular sealing projection on the inner walls and is hollowed out of its flat face, is hollowed out on its throat. In the actual insemination, the end of this and the hollow extension is cut off and the insemination tube (pipette) is placed on the remaining part of the extension (with the hole formed). The walls of the container are reinforced in the region of the cylindrical neck by the formation of folds or ribs, respectively. by strengthening the container walls in this region.

The container (bottle) described above is easy to fill and, when made of non-toxic material such as polyethylene, provides good conditions for short term storage of sperm.

The disadvantage of such a container, respectively. The fact that, due to its shape and relatively large wall thickness, it does not allow for a sufficiently sensitive control of the insemination process, thereby deteriorating fertilization conditions. In addition, in the manufacture of such containers, unnecessarily large amounts of material are consumed, which in practically one use becomes waste. This is not suitable either from an economic point of view (unnecessarily high costs of material and energy in production, reflected in the price of the product, increased storage and transport costs, etc.), or from an ecological point of view (unnecessarily high cost of landfilling, respectively. to another method of liquidation).

From these aspects, it seems more advantageous to use a semen bag having an outlet in the form of a tubing. These bags give a significantly better possibility of sensitive control of the insemination process and are more storable. Their disadvantage, however, is both the material used - they are mostly made of polyvinyl chloride (in which the sperm mortality is higher than that of polyethylene - reaches up to 40%) and secondly a great labor in production. Complications in practical operation can also make it difficult to plug the PVC tubing.

At present, a very widespread device for insemination is an insemination tube. It is formed by a cylindrical or conical body, which at one end thereof has a sharply delimited conical transition region and becomes a closed thin conical tapering tip. The other end of the tube is open, closed by welding until the tube is filled with sperm in the filling line. The advantage of insemination tubes is their low weight, good shelf life in the empty state (they insert into each other), easy filling and relatively good comfort during the insemination itself. Their drawback, however, is the need to trim, respectively. cutting off a portion of the tip of the tube prior to use and the associated polymer waste which is not desired in the cattle housing area. Another problem is the connection of the tube with the insemination pipette. Only the given type of pipette corresponds to the given size of the tube and even the connection of the tube with the correct type of pipette is not reliable enough (it is necessary to insert an even narrower end of the tube into the narrow pipette opening). This, together with the lack of rigidity of the end portion of the tube (due to sharp shape transitions) often results in kinking and constriction of the tube mouth or even falling out of the insemination pipette during insemination.

These drawbacks of the insemination tubes are largely overcome by the insemination applicator container, consisting of a hollow thin-walled body of a flexible material having an oval shape, a volume of 50 to 100 ml and a maximum wall thickness of 1 mm. This thin-walled body on one side smoothly merges into a conically extending integrally connected neck, which can be closed by a removable plug at the end; the body has a flat bottom on the side opposite the neck. From a dimensional point of view, the hollow thin-walled body of the dispensing container preferably has a width of 30 to 80 mm and a height of 10 to 30 mm. The neck of the applicator container preferably has an inner diameter of 5 to 7 mm in its narrowest part, preferably 25 to 50 mm in length. On its outer wall, the throat can be provided with transverse grip ribs and at the end with a hem. The plug of the applicator is preferably conical in shape. It is hollow with a central conical cavity. It may have a skirt at the outer end, optionally supplemented by grip wings.

From the point of view of its own use, the well-designed application container for insemination also has two drawbacks. One harvest is a difficult and slow filling of the container through a narrow neck, the other is a solution of the stopper for closing the neck as a separate additional part of the container, which becomes unsuitable waste during the insemination.

The essence of the technical solution

The insemination of the cartridge according to the present invention, made in a manner similar to the known insemination of the device from a flexible material, contributes to the elimination of the drawbacks of known insemination devices. The essence of the technical solution consists in that the insemination of the cartridge is formed by a hollow thin-walled body of conical shape, which on its narrow side smoothly merges into an integrally connected neck, formed by a cylindrical transition region and a conically widening mouth.

The insemination of the cartridge can be produced in two basic variants. In a tube design (in terms of a filling method similar to the tube insemination described above), the hollow thin-walled body of the cartridge insemination is terminated on its wider side through a filling opening and the mouth of the neck is blinded by a thin foil (blank).

In the embodiment of the bottle (in terms of filling similar to the container insemination described above), the hollow thin-walled body of the insemination cartridge is terminated on its wider side by a round bottom. In this case, the neck of the neck can be plugged with a special stopper or subsequently sealed with a thin foil (blank).

In both variants, the neck can advantageously be provided with an edge in the end region of its mouth and transverse grip ribs on its outer wall.

The main benefit of the insemination of the cartridge according to the present technical solution is its optimized construction, combining the advantages of all known insemination devices. The described turtle solution enables a firm and reliable connection with insemination pipettes of different types and sizes throughout the insemination. The design of the throat also avoids kinking or strangulation, common to the thin tips of hitherto used insemination tubes.

The thin-walled conical body enables perfect grip in the palm and highly sensitive compression. This allows very sensitive work during insemination and easy and reliable control of its progress. The flexibility of the container simplifies handling in the third phase of insemination - blowing the rest of the semen from the cervix into the uterus with air (the insemination bags used so far had to be blown by mouth at this stage).

In this case, it is possible to maintain an advantageous method of filling through the filling opening, known in particular for insemination tubes. It is also very advantageous to close the mouth of the throat with a thin foil (blank), which is easily perforated immediately before the insemination itself, without any undesirable waste.

Examples of technical solution

Example 1

The semen insemination cartridge of an exemplary embodiment (see Fig. 1) is made of a compliant polymeric material - in particular branched polyethylene. It is formed by a hollow thin-walled body J of conical shape, which on its narrow side smoothly merges into an integrally connected neck 2 formed by a cylindrical transition zone 3 and a conically extending orifice 4 connected thereto.

In the embodiment of this example, it is a tube variant (similar to an already used insemination tube). The hollow thin-walled body J of the insemination cartridge is, on its wider side, terminated by a filling opening 7, which after being filled with semen in the filling line is welded. The mouth 4 of the neck 2 is blinded by a thin foil 6 (blank) which is perforated by inserting the inlet tube 9 of the insemination pipette immediately prior to the actual insemination (shown in FIG. 3).

The neck 2 is provided with a reinforcing rim 5 in the end region of its mouth 4 and transverse gripping ribs 8 on its outer wall (see FIGS. 1 and 2).

Example 2

The basic parts, overall shape and solution of the throat 2 of the insemination cartridge are similar to Example I (see Fig. 1). In this case, however, it is a variant of the flacon (in terms of the way of filling with the throat 2 similar to the used insemination container).

In this embodiment, the hollow thin-walled body and the insemination cartridges on their wider side terminate in a round bottom 7 '(shown in dashed lines in FIG. 1).

In this case, the mouth of the neck 2 can be plugged with a special stopper (not shown in Fig. 1) or additionally sealed with a thin film 6 (blank) after filling the container with semen - see Fig. 1
