Definitions

• the present invention relates to a fluid transfer device between a container containing for example a drug or any ingredient (in solid or liquid form) for its preparation and an injection means.
• the invention relates more particularly to a perforating needle.
• the ingredients are commonly supplied in containers.
• the product contained in a vial is transferred by means of a syringe or by pressure difference to the preparation device, for example a syringe or to a specific preparation or synthesis device, in order to constitute the drug or one of its precursors.
• the product is supplied in liquid form in a vial while in other cases, it is in the form of a solid, for example powder or freeze-dried.
• a powder When it comes to a powder, it is most often deposited or evaporated on the bottom of the bottle. To recover this powder, a solvent must be introduced into the flask to dissolve the powder. The reconstituted product is then removed from the vial and transferred to the place of use.
• a hollow perforating needle as known from the state of the art provides a means of fluid communication with the contents of the vial.
• the tip can pierce the septum, allowing to insert a solution or to empty the contents of the vial.
• a conventional needle is composed of a sharp tip and a hollow access tube allowing a fluid to flow for example from an infusion bag as described in US Patent 6,261,267 B1.
• the solution continues to flow until the meniscus of the fluid in the vial falls below the end of the tip, leaving a certain amount of residual liquid in the vial.
• the products contained in containers in small quantities are metered with precision required by the preparation method or clinical indication. This precision can be important. Therefore, failure to recover all of the product contained in the vial may result in variations in the quality of the preparation or the amount transferred.
• a conventional perforating needle as shown in Figure 1, comprises a central channel 11 ending in an orifice which is in the extension of the channel.
• the piercing needle 1 of FIG. 1 is represented in a bottle 2 after having pierced the septum 6.
• This needle 1 comprises a cylindrical body 3, a stop 4, and a pointed end 5.
• the cylindrical body 3 extends from a distal end 9 of the needle to a proximal end 10. At its distal end 9 the cylindrical body 3 has a side wall 12 surrounding a central channel 11 terminated by an orifice at the pointed end 5.
• Such a needle makes it possible to send a vertical jet of solvent that can reach the top of the bottle (or the bottom of the bottle as it is reversed) and thus recover in the solvent all of the reagent present, including s it is deposited in solid form on all the inner walls of the bottle.
• a piercing needle does not empty the bottle in its entirety. There will always remain a fraction of unrecoverable fluid 7 below the level of the orifice of the tip 5 (see FIG. 1D).
• the piercing point is eccentric which causes misalignment of the vials with respect to the axis of the needle and is problematic in automated systems. Finally the eccentric points are generally less sharp.
• WO 2009/029010 A1 discloses another needle comprising at least one side opening for emptying a vial completely. Such a perforating needle is shown in FIG. 2.
• the perforating needle 1 comprises a central non-opening channel 11 and two lateral openings 8 at its distal end 9. The opening is located just above the septum 6 so that all the fluid contained in the bottle can flow through the lateral opening 8 in the central channel 11.

• the device of the invention is intended to allow both to optimally inject a liquid in a vial containing a prior product in solid form dispersed on the inner wall or in liquid form to recover it entirely in the liquid and extract the solution or mixture thus formed from the vial by completely draining the liquid into the vial, leaving no residue.
• a first aspect of the present invention relates to a perforating needle, also called “spike”, intended to be introduced into a bottle through a plug or septum for injecting and extracting a fluid, said needle comprising:

• the perforating needle is intended to be introduced into a bottle to be pierced to inject and / or extract a fluid.
• the reagent When the reagent must be stored in solid form, it is generally deposited on the walls and more particularly on the bottom of the flask by evaporation or lyophilization techniques known to those skilled in the art.
• the solid reagent is recovered by introducing a suitable solvent via the piercing needle and then aspirating the solution in which the solid reagent has dissolved or has been entrained. This requires to be able to fully wet the inner surface of the bottle.
• the perforating needle is made of rigid plastics material
• the perforating needle is intended to be introduced into a bottle comprising a plug made of elastomer or plastic material;
