Definitions

  • the invention relates generally to the preservation of a predetermined dose of liquid-based substance, and more particularly to flakes for effecting such preservation.
  • Such straw comprises a tube and a plug disposed in the tube.
  • the plug is usually of the tripartite type originally described in the French patent 995878 , corresponding to the British patent 669.265 that is to say formed by two buffers of fibrous substance enclosing a powder transforming in contact with a liquid into a paste or impermeable gel adhering to the wall of the tube so that the cap is liquid-tight.
  • plugs of another type for example a plug comprising or associated with an insert described by the French patent application. 2,771,284 corresponding to the US patent 6300125 , by the French patent application 2,771,285 corresponding to the US patent application 2001/0014376 , by the French patent application 2,784,572 corresponding to the US patent 6416611 and by the French patent application 2,932,064 ; or a plug made of a monobloc cylinder of hydrophobic microporous material described by the European patent application 0 873 726 ; or finally a plug made of a monoblock cylinder of self-sealing sintered microporous material described by the application PCT WO 2010/070533 .
  • the US patent 6305585 discloses a straw according to the preamble of claim 1.
  • the stopper In the initial state, the stopper is disposed in the vicinity of one of the ends of the tube and it is expected that in the filled state, the dose of liquid substance that must be stored in the straw is disposed between the stopper and the other end of the tube (end farthest from the plug).
  • the end closest to the plug is placed in communication with a source of vacuum while the end farthest from the plug is placed in communication with a container containing the substance to be introduced into the straw.
  • the air initially contained between the plug and the end of the tube furthest from the plug is sucked through the plug as the substance progresses in the tube until it meets the plug.
  • the straw is welded in the vicinity of one or both ends and is stored cold.
  • the straw and in particular the material of the tube are provided so that cold storage can be performed by immersing the straw in a liquid cryogenic agent such as liquid nitrogen.
  • the invention aims to provide such a straw that offers operators new capabilities while remaining simple, convenient and economical to manufacture and use.
  • the inner conduit of the syringe needle can thus be placed in communication, via the internal conduit of the stopper, with the space inside the tube located between the second end of the stopper and the second end of the tube.
  • This internal space in the tube is intended, as in conventional flakes, to receive the predetermined dose of liquid-based substance.
  • a syringe needle for example an injection needle
  • the dose of substance contained in the straw is drawn towards the stopper, for example as explained below. afterwards, the substance will pass through the internal duct of the stopper and then the internal duct of the needle and may be expelled at the distal end of the needle, that is to say the pointed end located on the opposite side to the needle. the female end of the needle.
  • the stopper is not moved to push the dose of substance towards the second end of the tube but that the stopper is fixed and that it is the dose of substance that is pushed towards the stopper and therefore towards the first end of the tube.
  • the straw according to the invention can thus play not only the role of a substance conditioning element of the substance for its preservation, including cryogenic temperatures (traditional role for a straw), but also the role of a body of syringe to which a syringe needle can be directly connected and whose contents can be ejected through the distal end of this needle.
  • the straw according to the invention makes it possible to prevent the dose of substance must be transferred from the conditioning unit that it constitutes to a syringe body.
  • the handling of the liquid-based substance is diminished, which is in some cases favorable to the preservation of its properties, in particular if the substance contains constituents sensitive to the mechanical stresses occurring during the passage in a narrow conduit such as the inner duct of an injection needle.
  • a substance is for example a vaccine comprising cells sensitive to mechanical stresses.
  • the flake according to the invention makes it possible to benefit from the conditioning qualities of the liquid-based substances offered by the flakes, from the compatibility with the existing cold-keeping devices of the flakes, including at cryogenic temperatures, for example the conventional cups for maintaining the flakes.
  • glitter in liquid nitrogen while providing the capabilities of a syringe body; and this simply by implementing in a thin tube of flake a cap configured accordingly.
  • the first end of the plug in an initial state before use, is located in the tube at a predetermined distance from the first end of the tube for welding the tube between the first end of the plug and the first end of the tube.
  • the tip and more generally the plug is isolated from the liquid cryogen by the tube of the straw and thus protected from any cross-contamination likely to be conveyed by the liquid cryogen.
  • the straw according to the invention would have a larger capacity but could not offer such an insulation capacity of the nozzle .
  • the plug in an initial state before use, has at its first end a cap to be removed closing said internal conduit of the cap.
  • This seal is of course to be removed before emptying the straw.
  • annular wall is disposed between the cap and the male end, the inner conduit of the cap extending beyond the first end of the male end in the annular wall to the operculum which the closure, the outer surface of the annular wall being recessed vis-à-vis the outer surface of the male end.
  • the lid is removed by cutting or even tearing the annular wall.
  • the remaining annular wall piece does not interfere with the engagement of the socket as the outer surface of the annular wall is recessed from the outer surface of the socket.
  • the cap comprises a body attached to the tube and an appendage protruding from said body attached to the tube only through the body, which appendix comprises said male end and extends to the first end of the plug.
  • the plug can be effectively secured to the tube by the body while the tube leaves free the outer surface of the tip.
  • the tube can be removed around the appendix after being cut.
  • the cap body and the tube are secured independently of a plug contact with said liquid-based substance.
  • the degree of securing between the tube and the plug is the same without prior contact and after contact of the plug with the liquid-based substance.
  • the invention also aims, in a second aspect, a device for injecting a liquid-based substance comprising a straw as explained above and a syringe needle having a female connection endpiece with frustoconical inner surface engaged on the male connection end cap of said straw.
  • the invention also aims, in a third aspect, a method of emptying a straw as explained above, comprising a dose of liquid-based substance disposed between the second end of the plug and the second end of the tube, comprising the step of pushing the dose of liquid-based substance towards the first end of the tube after connecting the tip of a syringe needle to the male end of the plug.

  • the plug 12 is made of a material which has the same properties of impermeability to gases and liquids without and with prior contact of the plug with a liquid, especially aqueous.
  • the stopper 12 does not include a powdered dry sealant that turns into a paste or gel once moistened.
  • the material of the plug 12 is here polyethylene, more specifically HDPE.

  • the plug 12 has an axisymmetric configuration and is arranged coaxially with the tube 11.
  • the plug 12 comprises a body 9 and an appendix 63 projecting from the body 9 and extending to the end 19.
