Definitions

  • the present invention relates to a veterinary instrument as defined in the preamble of claim 1 starting from document WO-A-90/07913.
  • the cannula only over a portion of length in the teat canal, so that the drug composition can be deposited directly inside the teat canal.
  • the length of the cannula which can be accommodated inside the opening of the tette channel corresponds to the dimension of the opening of the tette channel.
  • the instrument includes: a container for containing a liquid or viscous drug composition, an elongated cannula extending from the container and forming a body with it, and a tubular cap made up of two parts which cover the cannula and can be detached in two parts.
  • the tubular cap indeed comprises a lower sleeve constituted by a removable entry flange which protects the cannula and an upper cap which is rigidly fixed to the lower sleeve and covers the free end of the cannula.
  • the sleeve is shorter in length than the cannula and extends only a portion of the length of the cannula.
  • the sleeve has an upper end having a substantially planar annular end wall, through which the cannula head can be introduced into the udder of the cow through the udder channel when the cap is detached from the lower sleeve.
  • the molding of the cap consisting of two parts is expensive, because it requires not only the acquisition of two different dies and the implementation of two different manufacturing but also an intensive labor since it is necessary to mount two different parts .
  • the flat end of the sleeve offers insufficient sealing and the disadvantage that soiling and secretions can be pushed back into the uterus channel and delay the healing of the cow's udder infection.
  • the flat annular end wall also has the drawback of creating an insufficient seal all around the periphery of the upper edge of the lower sleeve when the latter is applied against the udder channel of the cow's udder.
  • This syringe is not intended for the treatment of mastitis. Indeed, nothing is planned to capture the impurities or dirt agglomerated around and in the orifice of the tette channel, at the entrance of the channel.
  • document EP-A-0323109 proposes an application for the treatment of mastitis consisting of a bellows, forming a container for a medicinal composition, on which is screwed a cap extended by a cannula covered with a removable cap.
  • the end edge of the cap forms an annular opening to trap impurities through which emerges the end of the cannula when the removable cap is removed.
  • the cap being made up of a single part, the applicator described does not allow any choice of the useful length of the cannula.
  • the present invention aims to remedy the above drawbacks and proposes a cap system which is detachable from the cannula in whole or in part only. It relates to a veterinary instrument for delivering a medicinal composition intended for the medical or veterinary treatment of an inflammation of the udder of a cow, a goat or a sheep, comprising the features of claim 1.
  • the upper cap of the cap of the cannula has a prominence by which the cap can be broken at the level of the annular notch which separates the upper cap from the sleeve.
  • the interior wall of the lower sleeve has projections directed towards the central axis of the lower sleeve, to keep the rather flexible cannula in the middle.
  • the annular orifice has upper edges, the thickness of which provides an air and water tightness zone around the injection point of the udder udder channel, when the drug composition is deposited in the tette channel.
  • the dimension of the upper edge of the periphery of the lower sleeve is chosen as a function of the biomechanical elastic limit of the skin and the flesh of the udder tette.
  • the cannula 3 has a tapered end which must be inserted by sliding into the udder channel 5 of the udder.
  • the length of the cannula is such that, when the cannula 3 is fully introduced into the tette channel 5, the composition drug can be injected directly into the udder 6 ( Figure 8).
  • the free end of the cannula 3 is closed by means of a cap 4 capable of being broken, which covers the cannula 3 over the entire length.
  • This breakable cap 4 is molded in one piece, but it has two parts: a sleeve 7 which is removably mounted on the cannula 3 and an upper part 8 which is part of the sleeve 7 and covers the free end of the cannula 3.
  • the sleeve 7 is shorter than the cannula 3.
  • the upper part 8 is partially separated from the sleeve by an annular notch 9.
  • the cannula When the cap 4 is detached, the cannula is released over the entire length and it can thus be introduced over the entire length into the udder teat channel.
  • annular opening 12 is formed around the last part of the cannula 3 and of the cap 4.
  • This annular opening 12 offers two important advantages.
  • this opening has the advantage that impurities, in particular secretions or stains, which are located in the vicinity of the orifice of the tette channel 5 on the outside of the udder, can be intercepted in said opening. , when the last portion of length of the cannula 3 is introduced into the tette channel, in which case any risk of introducing stains into the tette disappears.
  • the annular opening 12 then offers the advantage of forming with the tette a watertight contact zone around the entire periphery of the upper edge 10 of the cap 4, in the vicinity of the injection point in the udder, by which prevents leakage of the drug composition to the outside during the injection of the drug composition.
  • the rounded edge 10 of the cap 4 is inserted into the flesh which surrounds the head 11 to a depth sufficient to obtain a sufficient airtightness.
  • the dimension of the contour of the upper edge 10 makes it possible to maintain the contact pressure at the biomechanical elasticity limit value of the skin of the pad 11.
  • the contact reaction zone extends over the entire periphery of the sleeve 7, so as to avoid everywhere a leakage of medicinal composition towards the outside.
  • a third advantage lies in the fact that the cap 4 can no longer be reused to close off the tip of the cannula 3, after the upper part 8 of the cap has been broken.
  • the upper part 8 of the cap 4 is in fact used as a sealing ring to guarantee the inviolability of the cannula. It ensures the sterility of the packaging of the instrument filled with medicinal composition.
  • the inner side of the cap includes a sealing cone 14.
  • the upper part 8 is distinguished from a conventional cap by the fact that the closed end is extended by a cylindrical projection 15 which is rigid enough to allow the thumb to rest on it to break the cap at its base and detach it from the cap. 4.
  • the cylindrical part 15 is preferably internally full and provided with external ribs 16 in order to reduce the consumption of synthetic material during molding.
  • the cap 4 according to the invention has the advantage of being able to be manipulated with one hand. This advantage is very important, when it comes to caring for animals that must be held gripped with the other hand.
