Definitions

  • the present invention relates to devices for transferring elements of animal reproduction, such as embryos (from a donor reproductive female and to be placed in a carrier female) or animal semen (taken from a male for the purpose of 'artificial insemination). It relates more particularly to devices of the purely mechanical ejection type, comprising a hollow and rigid main body, of generally cylindrical shape, at one end of which is fixed a flexible tube which extends the main body outwards, this tube having to serve as reservoir to the reproduction elements, while this main body internally receives, at its other end, a piston rod with which is associated a sliding piston, the free end of the reservoir tube comprising, moreover, an ejection nozzle with axial passage, the body being able, moreover, to be advantageously surrounded externally, over at least a large part of its length, by a protective sheath fixed on it, which is changed at each operation, which avoids sterilization of the apparatus.
  • the tube -reservoir is housed, over most of its length, inside the rigid body, and the piston is directly actuated by the end of the rod whose length is roughly equal to that of the body (similarly besides that of the protective sheath, when provided, in which case the end piece is, moreover, interposed between the end of the reservoir tube and that of the sheath which both protrude slightly from the body) .
  • the entire apparatus is rigid over its entire length and the rod and piston assembly is used at least to push the reproductive elements into the womb of the breeding female, in the case of semen , in that of the carrier female, in the case of an embryo.
  • This same rod and piston assembly may, moreover, have already been used, in addition, for the aspiration of the semen in a particular embodiment of the first case.
  • it is a reservoir tube previously filled with semen, or a suspension containing the embryo, and in general stored under refrigeration, after removal from the male or the breeding female, which is fixed on the body of the device, a tampon which seals the end of the tube then serving as a piston during ejection.
  • the free end of this device should, in principle, be inserted beyond the vagina and cervix, as far as possible inside the uterus of the animal, to ensure a deep deposit of the semen or embryo and therefore facilitate reproduction or implantation.
  • the uterine lining is extremely fragile (particularly in the case of an embryo transfer, which should normally take place outside the period of oestrus), so that these known devices risk, made of their rigid end, to cause a lesion of this mucosa with all the consequences that this entails.
  • the known devices for example the aforementioned patent FR -A? 2477006
  • the known devices in fact only allow the establishment of the embryo in the carrier female, the collection on the female reproductive using an entirely separate device and operating of a completely different type, since by fluid circulation (such as that described in the French patent of holders FP-AN No. 2477005).
  • the delivery device must receive a reservoir tube already filled with the embryo suspension.
  • the main object of the present invention is to minimize the risk of damage to the uterine lining and, for this purpose, it relates to a transfer device of the aforementioned type, in which a rigid main body is surrounded by a second rigid body. characterized in that this main body can slide inside said second body which has approximately the same length as the latter, while the piston rod comprises a front section which is flexible and has a length at least equal to that of the tank tube.
  • the device can, in in addition, include a fixing sleeve rigid which can surround the reservoir tube and which has, at one end, means for retaining the nozzle fixed to the front end of the reservoir tube, and at the other end, means for pressing on the front end of the outer body, this sheath favoring the maintenance of the reservoir tube, which is flexible, while it is fixed to the end of the main body, for example by interlocking, while simultaneously ensuring perfect asepsis of the operation .
  • a fixing sleeve rigid which can surround the reservoir tube and which has, at one end, means for retaining the nozzle fixed to the front end of the reservoir tube, and at the other end, means for pressing on the front end of the outer body, this sheath favoring the maintenance of the reservoir tube, which is flexible, while it is fixed to the end of the main body, for example by interlocking, while simultaneously ensuring perfect asepsis of the operation .
  • a protective sheath it can very advantageously be arranged around the external body, so as to protrude slightly at the front thereof, by presenting at its front end a rounded inner hem, while it is, moreover, fixed on the same outer body at its opposite end, which allows, when the main body recedes, to fully return the reservoir tube inside this sheath , the hem of the latter avoiding any lesion of the mucosa during introduction into the uterus.
  • the end piece fixed to the end of the reservoir tube has, at the front, a rigid spherical head, which can pass elastically through the hem of the sheath, while its central passage opens out.
  • the spherical head due to its shape, progresses easily and without damage in the uterine lumen.
  • the object of the invention is also to make it possible to carry out, using the same apparatus, the aspiration sampling in the empty reservoir tube of the suspension containing the embryo (s), and this in an intermediate storage container, without that it is necessary to use other specialized devices for this purpose.
  • the apparatus according to the invention is, furthermore, characterized in that the flexible front section of the piston rod carries, at its front end, the ejection piston and is separated from the rear section of the rod which is rigid.
  • the subassembly of the device constituted by the reservoir tube and the flexible front section of the rod can be separated from the rest of the device to operate like a syringe for aspirating, in a storage container, the suspension containing the embryo, this sub-assembly then being reattached to the rest of the device to allow introduction and ejection in the manner already indicated.
  • the apparatus may also comprise a rigid guide sleeve which can surround the reservoir tube and which has, at one end, means for retaining the end of the reservoir tube opposite to that which must receive the tip, this sheath favoring the maintenance of the reservoir tube during the aspiration of the suspension, which avoids, during handling, any twisting which could block the aspiration of the embryo, while ensuring the asepsis of this operation.
  • a rigid guide sleeve which can surround the reservoir tube and which has, at one end, means for retaining the end of the reservoir tube opposite to that which must receive the tip, this sheath favoring the maintenance of the reservoir tube during the aspiration of the suspension, which avoids, during handling, any twisting which could block the aspiration of the embryo, while ensuring the asepsis of this operation.

  • the outer diameter of this tube 3a corresponds to the inner diameter of the tube 2a of the main body, and its length is somewhat shorter than that of the outer body 1, so that when this rear piston rod element 3 is introduced into the inside the main body 2 until, as also shown in FIG. 11, the two gripping heads 2c and 3c, forming abutment means, come to bear one on the other, the front end of the tube 3 remains slightly set back relative to that of the body 1.
  • the reservoir tube 4 (fig. 4) is a perfectly cylindrical tube over its entire length, and made of a flexible plastic material, such as flexible polyvinyl chloride. Its outer diameter is substantially equal to that of the main body 2 and its inner diameter substantially equal to the diameter of the grooves 2g, located at the front end 2h of this tube, so that, as shown in fig. 11, the rear end 4a of the reservoir tube can be fitted elastically over the two frustoconical bearing surfaces 2d and 2e of the main body, until it comes into abutment against the rear shoulder of the rear groove 2g.
  • the length of this tube is provided so as to correspond, on the one hand, to a normal volume of the suspension containing the embryo (s) that this tube must contain, and, on the other hand, to the average length of the genital tract of the female.
  • the flexible front section of piston rod 5 (fig. 5) consists of a solid rod or a rod, also made of flexible plastic, such as flexible polyvinyl chloride.
  • the diameter of this rod is quite clearly less than the inside diameter of the reservoir tube 4, so that, when this rod is disposed inside this tube, as shown in FIG. 11, there remains a substantial radial clearance between them, this same diameter of the rod corresponding, moreover, very precisely to the diameter of the bore 3e of the rear piston rod element 3, which allows it to be able to come fully engage it, as shown in fig. 11.
  • the length of this rod is approximately of the same order of magnitude as that of the reservoir tube 4.
  • the end piece 6 (fig. 6) is a piece of stainless steel, of generally short cylindrical shape and which comprises, at its rear end, a frustoconical interlocking surface 6a, converging towards the rear and separated from the current part cylindrical by a groove 6b, while at its front end is welded a spherical head also made of stainless steel 6c, of slightly larger diameter, a central passage 6d finally extending over the greater part of this endpiece to open axially at the rear, while it opens on the side and at the rear of the spherical head 6c, using a 6th elbow.
