A machine to make up doses of semen in a container comprising welded thermoplastics films that can be opened by hand without using instruments in order to insert therein an insemination probe includes a tubular needle having a nozzle over which is threaded a cleaning ring to prevent coating of a region to be sealed by welding with semen and to keep the walls of the thermoplastics films dry after filling the dose with semen. The sealing weld is made by a device having inverted U-shape jaws. An incision perpendicular to the branches of the U-shape is made at the same level as the latter by an incision device including an orientable blade.

This instrument is of the type comprising a hollow body housing a reservoir tube for reproductive components, 4, which receives an ejection piston rod and which is closely enveloped by an external protective sheath 7 having, at its distal end 7b, retaining means 9 inside which the projecting end of the reservoir tube bears.The problem to be solved consists in making it possible to avoid causing any lesions and carrying along any mucus and also to construct instruments of very small diameter.According to the invention, the retaining means 9 on the sheath 7 comprises a terminal 9 with a solid rounded head or distal end 9b and with a blind axial passage 10 open towards the cylindrical body 1 and communicating with the outside at its blind end by means of a lateral transfer orifice 10c.The invention has an advantageous application in the transfer of animal embryos.

The invention relates to an animal enclosure. Prior animal enclosures, especially batteries of cages, have posed problems of manufacturing cost, noise and inconvenience of door actuation, and risk of injury to the animals inside. The present invention provides an animal enclosure in which a loop and frame move along a path. The frame has an opening in it so as to provide access to the enclosure and the loop otherwise closes off the enclosure. The invention is applicable to cattle pens and to batteries of poultry rearing cages.

The syringe is of the type comprising a tubular body 1 adapted to receive a supply of product to be injected and in which is slidably mounted a push-rod for expelling the product from the supply, and a flexible sheath 3 which surrounds the tubular body and is detachably fixed around a holding end 4 of the body. The holding end 4 of the tubular body has projections 6 whose height, measured from the axis of the body exceeds the inside diameter of the fixing end of the sheath 3.

The invention concerns a syringe for injecting the content of a straw enabling the reading of data borne by the straw, even when it is ready for use. The straw is placed in a tubular body (12) of the syringe in a housing (30) wherein is provided at least a lateral window (38).

A device for collecting seminal fluid, comprises a collecting container (1) on which is mounted an adaptor (2) provided with a cannula (3) for sucking up the seminal fluid under the effect of a partial vacuum. The device further includes an adaptor sleeve (5) interposed between the container (1) and the adaptor (2). The sleeve comprises a chamber (10) in communication with the adaptor (2) in which chamber a filter (11) for the seminal fluid is located. A pipe (16) for sucking up the fluid and having a first flared end portion (17) emerges on the filter (11) and a second end portion (18) emerges in the container via a projection (19) extending axially beyond the end (20) of the sleeve pointing towards the container. A sucking-up duct (21) intended to be connected to a source of partial vacuum terminates at the end (2) of the sleeve inside the container in order to generate, within the container (1), a partial vacuum intended to bring about the sucking-up of the seminal fluid through the filter (11).

The tube, known as a straw, according to the invention, is conventional in its form, and is constituted by a rectilinear length of transparent tubular envelope. In the vicinity of a first end, the straw contains a sliding stopper with a quantity of powder gellable by hydration between two porous pads. The tubular envelope is extruded from an ionomer resin marketed under the brand name of Surlyn 8921. Ionomer resins have, above and below a transition zone extending from 45.degree. C. to 60.degree. C. approximately, states that are respectively thermofusible and crosslinked. Thus, the straw can be closed by fusion of the ends clamped by heated jaws, while presenting suitable properties of rigidity at ambient temperature. Furthermore, the ionomer resin used does not have an embrittlement temperature, so that it can be manipulated at cryogenic temperatures (77 K.) without the need for taking any particular precautions. The filling and sealing of the straws can be automated, to ensure the safety of the operators.

The invention relates to apparatus for artificial insemination of animals, and particularly carnivores such as dogs, foxes, wolves and even smaller animals such as mink.The apparatus comprises a flexible probe having apertures at each end, in which is mounted slidingly a semen reservoir tube, which is also flexible, a projecting end of the semen tube presenting a head and an orifice behind said head through which the semen is ejected from the tube, the other end of the semen tube being coupled with a sheath having a removable abutment limiting the stroke of the sheath and tube in the probe, a piston extending through the sheath to engage in the tube for actuation to eject semen therefrom, and balloons extending externally round the probe for inflation once the probe is disposed in the vaginal cavity of the animal by compressed air blown through a separate conduit in the probe from that receiving the semen tube.

The invention relates to "insemination guns" comprising an elongate body (1) at the front end of which is fixed an insemination tube (10) ("paillette") and within which is slidingly mounted an ejection rod for ejecting the tube, while an air supply is connected by an air flow passage to the tube (10) at the front end (5a) of the body.The problem posed is to provide such an apparatus which is easy to manipulate and simple to maintain.According to the present invention, the ejection rod (6) has at least one flat (16) cooperating with the circular section wall of the conduit (5) in which the ejection rod is mounted to define the air flow passage (17) beside the ejection rod (6) in the conduit.The invention is especially applicable to inseminating turkeys.
摘要:
The sheath is of the type having a thickness which is substantially constant throughout its length and having at a first end, or insemination end, a narrowed shape (4b).The problem is to provide a sheath which may be employed on an insemination gun which fixes the sheath by means of projections without presenting difficulties when manufacturing or when inserting the sheath.According to the invention, this sheath is characterized in that its opposite end portion (4a), or fixing end portion, of very short length relative to the total length of the sheath, has an inside diameter substantially larger than the constant inside diameter it has throughout the remainder of its length. The invention has an advantageous application in respect of sheaths for insemination guns for bovines.
