Abstract

Diffuser for cannulas of insemination devices, applicable in those types of devices for artificial insemination of sows, wherein the device includes a cannula arranged longitudinally and axially inside a catheter, the cannula being longer than the catheter, the posterior end of such cannula being associated to the corresponding container containing the semen to be applied, the catheter being topped in a thicker end and the cannula in correspondence with its anterior end with a diffuser through which the semen is destined to exit. Deposited on the cervix of the bristle, characterized in that said diffuser is constituted by an elongated body, of contoured profile, in which a flat frontal extremity is defined, endowed with a central orifice, counting on two lateral holes, diametrically opposed, finishing off later in a neck of insertion to pressure in the breast of the corr spontaneous cannula.

Description

DIFFUSER FOR INSEMINATION DEVICE CANNULAS

OBJECT OF THE INVENTION

The present invention relates to a diffuser for insemination device cannulas, specifically for artificial pig insemination devices that basically comprise a catheter in which a cannula is housed through which semen is introduced into the uterus of the animal to inseminate.

The object of the invention is to provide the market and the public in general with a diffuser for the cannula of this type of devices, which presents a series of particularities from which advantages and new benefits are derived from those offered by conventional diffusers.

BACKGROUND OF THE INVENTION

As is known, in the artificial insemination of sows, a device participates by means of which the corresponding semen dose is applied to the body of the sow's uterus.

In this sense, devices based on a tubular catheter through which the cervix is reached to deposit the corresponding dose have long been known.

There are numerous types of catheters to produce such insemination, with problems and disadvantages of both efficacy and discomfort and even the possibility of causing damage to the sow's uterus.

Such devices are constituted from a catheter in whose interior a cannula is arranged axially longer than the catheter, so that the cannula in question, which is connected at its rear end to the corresponding semen container to be applied, has at its anterior end a diffuser constituted by a spherical general configuration element coupled through a neck in the

end of the cannula and equipped with a pair of holes for semen exit.

This type of diffuser, regardless of the spherical configuration that presents at its end, the arrangement of the two holes that it includes, arranged in diametral opposition, requires a manipulation of the cannula to conveniently orient said holes so that the semen outlet is made over a specific point of the cervix of the sow, which requires a skill on the part of the manipulator that sometimes is not enough, with the problems and inconveniences that derive from it.

On the other hand, the existence of two holes in said diffuser, means that the output flow is reduced, requiring great pressure to achieve a correct dose, pressure that can lead to the semen being projected outward subjecting the sperm to excessive force.

DESCRIPTION OF THE INVENTION

The recommended device solves in a fully satisfactory way the problem described above, based on a simple but extremely effective structure.

To do this, and more specifically, being provided for mounting on the front end of a cannula of an artificial bristle insemination device, it is characterized in that instead of presenting its rounded end, it has a contoured configuration, to avoid damaging the fragile internal tissues of the sow reproductive system.

In addition, the actual end of the diffuser is flat and in it a front hole is defined which, in combination with two side holes in diametral opposition, allows an increase in the output flow and therefore a decrease in semen pressure to be achieved. projects, eliminating with it all the problems and inconveniences referred to in the previous section.

Finally, say that the diffuser presents in its coupling on the end of the

cannula, a tubular section with a series of annular teeth through which a pressure assembly and consequent consolidation of the diffuser on the end of the cannula is performed.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a representation corresponding to a perspective view of a diffuser for insemination device cannulas made in accordance with the object of the present invention.

Figure 2 shows a view in diametral section of the device of the previous figure, but coupled at the end of the corresponding cannula.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the figures outlined, the diffuser of the invention is constituted by a body (1) with a neck (2) through which it is coupled to the corresponding cannula (3), specifically on the front end thereof, and belonging to a device for artificial insemination of sows, whose cannula (3), as is conventional, is mounted axially and with a greater length, on a catheter, not shown, as it is a conventional and usual element in this type of device.

The neck (2) of the body (1) of the diffuser has annular teeth (4), of trapezoidal section, through which it is perfectly adjusted to the end of the cannula (3), as can be seen in Figure 1.

From these characteristics, the fundamental novelty of the diffuser of the invention is constituted by the fact that its limb is not spherical and closed as occurs in the

conventional inseminating devices, but it has an end face (5) with a contoured profile, that is to say rounded but longitudinally elongated, with the particularity of being affected by a front hole (6), in correspondence with the end face (5), and two lateral holes (6 ') arranged in diametral opposition.

In this way, by means of the front hole (6) and the side holes (6 '), it is possible to increase the flow of semen that is applied to the uterus of the sow, thereby reducing the pressure with which it is projected towards the Exterior.

10 In addition, by virtue of said decrease in pressure, the force to which the sperm are subjected is equally reduced, and thereby increasing the effectiveness of the insemination process itself.
