Description
Technical Field
The present invention relates to a device for artificial insemination of animals, which allows to insert and fix in place the animals without disturbing them.
Background
For oestrus animals, in particular sows, the application of semen doses is usually carried out vaginally using an instrument called a tubular sleeve, which, although of different shape, is used in each case to reach the cervix and to fix it at the first few centimetres, allowing the semen dose to be applied through it, which must pass through the rest of the cervix until reaching the cervix.
There are a variety of types of cannulas, from classical reusable cannulas made of rubber or similar materials, to almost endless list of disposable plastic cannulas.
Disposable plastic cannulas are typically composed of three components, corresponding to a handle, a shaft, and an end or tip, such that the handle (not present in all cannulas) is a small component for easy gripping of the cannula.
The stem or body of the cannula is a tube of approximately 50 cm length, which serves as a conduit for semen, the diameter of which is variable, but in any case its external dimension does not exceed 10 mm.
The tip, which is the main element of the cannula, is a variable-size and shape component that can be inserted and fixed in the cervix in any case. For example, there are cylindrical tips (caps) made of foam, and also conical tips made of various types of plastic and of widely varying sizes.
A problem with this type of sleeve is that if no fixing element is used, the sleeve is not fixed in place and its operation is incorrect.
For this reason, it is common to use a fixation element arranged on the cannula. In these cases, the attachment to the cervix is generally facilitated by the shape of the fixation element, which increases the quality of the coupling between the sleeve and the irregular portion of the cervical wall. However, the presence of these fixation elements can interfere with the animal, thereby affecting insemination.
An example of an insemination device of this type is disclosed in document WO 2001/049205 A1. This document discloses an artificial insemination device comprising a cannula provided with a tip and a helical fixation element arranged on said cannula.
Another example of an insemination device of this type is disclosed in document EP 3725266A1, wherein the sleeve has the same rigidity over its entire length.
Disclosure of Invention
It is therefore an object of the present invention to provide a device for artificial insemination of animals which is fixed in place but which does not interfere with the animal during insemination.
The above-mentioned drawbacks are solved and other advantages are presented by the device for artificial insemination of animals according to the present invention, which will be described hereinafter.
The following describes a device for artificial insemination of animals according to the present invention and includes additional optional features.
In particular, the device for artificial insemination of animals comprises:
A cannula to be inserted into the cervix of the animal to be inseminated;
An insertion tip disposed at one end of the cannula, the insertion tip being provided with a hole;
a fixation element disposed on the cannula to secure the cannula in place during insemination; and
A reinforcing element that reinforces a portion of the sleeve.
In this way, the stiffening element makes a portion of the sleeve more rigid than the rest of the sleeve, thereby facilitating the insertion of the insemination device according to the invention.
Furthermore, the stiffening element defines an insertion portion in the sleeve without the stiffening element, the insertion portion having a stiffness that is less than a stiffness of the stiffening portion of the sleeve.
According to an embodiment of the artificial insemination device according to the invention, the stiffening element is accommodated within a portion of the cannula. Furthermore, the stiffening element is preferably tubular.
Preferably, the length of the insertion portion is less than the length from the fixation element to the insertion tip. In this way, the stiffening element extends beyond the fixation element towards the insertion tip.
According to a preferred embodiment, the fixation element comprises a tubular portion, a first frustoconical portion and a second frustoconical portion, said first frustoconical portion and second frustoconical portion being made of a flexible material.
In particular, the first and second frustoconical portions define a larger diameter end and a smaller diameter end such that during insertion of the cannula the larger diameter end is further from the insertion tip and during extraction of the cannula the larger diameter end is closer to the insertion tip.
Furthermore, the cannula preferably comprises an insertion indication.
According to a preferred embodiment, the diameter of the larger diameter end of the first frustoconical portion is smaller than the diameter of the larger diameter end of the second frustoconical portion, and the first frustoconical portion is arranged closer to the insertion tip than the second frustoconical portion.

Fig. 2 is a perspective view of an artificial insemination device according to the present invention in its removed position.
Detailed Description
As shown in fig. 1 and 2, the device for artificial insemination of animals according to the present invention comprises a sleeve 1, the sleeve 1 being a tubular element inserted into the cervix of an animal to be inseminated.
To facilitate its insertion, the cannula 1 comprises an insertion tip 2 at one end thereof, said insertion tip 2 comprising a hole 7 to allow the semen to escape through the hole for insemination of the animal.
In order to allow the fixation of the cannula 1 in place during insemination, the insemination device further comprises a fixation element 3, which fixation element 3 is arranged on a part of said cannula.
Furthermore, the device for artificial insemination of animals further comprises a stiffening element 10, which stiffening element 10 stiffens a portion of the sleeve 1 such that the stiffness of the stiffening portion of the sleeve 1 increases.
The stiffening element 10 defines an insertion portion 9 in the cannula 1 without the stiffening element 10, which insertion portion 9 has a lower stiffness than the stiffening portion of the cannula 1, which facilitates insertion of the cannula for insemination of animals.
According to the embodiment shown, the reinforcing element 10 is a tubular element housed within the reinforcing portion of the sleeve 1.
Furthermore, as shown, the length of the insertion portion 9 is smaller than the length from the fixation element 3 to the insertion tip 2, i.e. the stiffening element 10 extends beyond the fixation element 3 towards the insertion tip 2, such that the insertion portion 9 is free of said stiffening element 10.
The fixation element 3 comprises a first frustoconical portion 4 and a second frustoconical portion 5, both frustoconical portions 4, 5 being arranged in a tubular portion 8, the tubular portion 8 being the portion immediately surrounding the sleeve 1.
The frustoconical portions 4 and 5 are made of a flexible material so that their orientation varies according to the direction of movement of the cannula 1 and also allow insertion and removal of the cannula without interfering with the animal.
The first and second frustoconical portions 4, 5 each comprise a larger diameter end 41, 51 and a smaller diameter end 42, 52, and the larger diameter end 41 of the first frustoconical portion 4 has a smaller diameter than the larger diameter end 51 of the second frustoconical portion 5.
Furthermore, the first frustoconical portion 4 is closer to the insertion tip 2 than the second frustoconical portion 5.
When inserting the cannula 1, the orientation of said first 4 and second 5 frustoconical portions is as shown in fig. 1, i.e. the smaller diameter ends 42, 52 are closer to the insertion tip 2 than the larger diameter ends 41, 51.
Conversely, when the cannula 1 is removed, the orientation of the first 4 and second 5 frustoconical portions changes due to the flexible nature of the material. That is, during removal of the cannula, the larger diameter ends 41, 51 are closer to the insertion tip 2 than the smaller diameter ends 42, 52.
To facilitate the correct positioning of the cannula 1 it comprises an insertion indication 6, as shown in fig. 1, for example, comprising some indication lines indicating the correct position of the cannula 1 at the insemination site, with a margin error of e.g. 2cm-3 cm.
While specific embodiments of the invention have been described, it will be apparent to those skilled in the art that the described device for artificial insemination of animals is susceptible to numerous variations and modifications, and that all the details mentioned may be substituted with other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
