Definitions

  • Adaptor with injection device for coupling to a medical container
  • the present invention relates to an adaptor for coupling to a medical container such as a vial containing a pharmaceutical product, such as a vaccine, said adaptor comprising an injection device and allowing for aseptic needle piercing of the septum of the medical container so as to fill said injection device with part of the product contained in the medical container.
  • the distal end of a component or apparatus must be understood as meaning the end furthest from the hand of the user and the proximal end must be understood as meaning the end closest to the hand of the user, with reference to the injection device intended to be used with said component or apparatus.
  • the distal direction must be understood as the direction of injection with reference to the injection device, and the proximal direction is the opposite direction, i.e. the direction of the transfer of the product from the medical container to the injection device.
  • the cold chain be not interrupted from production of the drug at a pharmaceutical company to its administration to the patient.
  • the most efficient vaccine packaging is the multidose container such as multidose vial, that is to say, vial that may contain up to 10, 100 or 1000 doses of vaccine, one dose being intended for one patient.
  • These vials are usually closed by a septum.
  • the user pierces the septum of the vial with the needle of an empty syringe, he then fills the syringe with one dose of vaccine and proceeds to the injection of the vaccine to the patient.
  • multidose vials imply that the septum of the vial be pierced successively a high number of times, namely as many as the number of doses present in the vial.
  • the sterility of the septum of the vial should be maintained during the whole time the vial is used.
  • the multidose vials may be handled and manipulated at ambiant air.
  • the septum of the vial may be contaminated either by the ambiant air, or, each time a dose of vaccine is removed, by the needle of the empty syringe used.
  • the multidose vials may be maintained in cold conditions by simple contact with ice packs. As time goes by, part of the ice may melt and turn into water, and the septum of the multidose vials may be in contact with such water that may contaminate the septum of the vial.
  • a multidose vial such as for example a 10- dose vial
  • a multidose vial is opened and that only three doses are used, for vaccinating three patients only, the remaining content of the vial being wasted because not intended to be administered in a sufficiently short time after opening of the vial in order to guaranty the vaccine or drug sterility.
  • Vaccination campaigns can therefore be made difficult in some regions and a significant proportion of vaccines may be wasted by the time they reach their target. This has an unacceptable cost to the health organizations in charge of immunization campaigns.
  • immunization campaigns or pandemic, hundreds of patients need to be vaccinated in a very short time, in locations where it is difficult to maintain favorable hygienic conditions such as remote locations which are far from towns and from hospital facilities.
  • a device that would allow several successive safe piercings of a multidose vial septum and that would guarranty that said piercings be carried out in aseptic conditions, in particular that the septum be made sterile at the time of injection act, or be maintained sterile during the lifetime of the multidose vial, and that would prevent wastage of the drug, even if the multidose vial is not stored in aseptic conditions.
  • a first aspect of the present invention is an adaptor for coupling with a medical container having a collar closed by a septum, said septum having an outer surface directed towards the outside of the medical container, said adaptor comprising an injection device provided at its distal end with a needle intended to pierce said septum via said outer surface in order to fill in said injection device with product from the medical container, the adaptor further comprising :
  • tubular lodging for receiving at least partly said injection device, said tubular lodging being substantially closed at its distal end by a transversal wall provided with a central hole in which is lodged a pierceable elastomeric piece having at least a distal face intended to be in contact with the outer surface of the septum when said adaptor is secured on said medical container, the needle of said injection device being aligned with said pierceable elastomeric piece and being movable within said tubular lodging with respect to said pierceable elastomeric piece between an inactive position, in which said needle is entirely located proximally to said pierceable elastomeric piece, and an active position, distally spaced with respect to said inactive position, in which only a part of the needle is located proximally to said pierceable elastomeric piece, the other part of said needle piercing said pierceable elastomeric piece and protruding out of said distal face of said pierceable elastomeric
  • tubular lodging further comprising a chamber filled with decontaminated air and receiving the needle or part of the needle located proximally to said pierceable elastomeric piece, the volume of said chamber being capable of varying from a first volume, when said needle is in its inactive position, to a second volume less than said first volume, when said needle is in its active position,
  • an air passage for allowing air coming in and out from said chamber, said air passage comprising a first filtering system for decontaminating the air coming from the outside before it reaches said chamber,
  • an air inlet for allowing air from the outside entering the adaptor and reaching the distal face of said pierceable elastomeric piece when said adaptor is secured on said medical container, said air inlet comprising a second filtering system for decontaminating said entering air before it reaches said distal face of said pierceable elastomeric piece,
  • the adaptor of the invention is intended to be mounted on a medical container, such as a conventional vial for storing pharmaceutical products, such as multidose vials for vaccines.

  • a vial 1 is shown on Figures 1A-1 C and generally comprises a tubular barrel 2 having a longitudinal axis A, closed at an end and having a collar 3 at the opposite end, said collar 3 being closed by a septum 4.
  • the septum 4 is fixedly attached to the collar 3 of the vial 1 by a peripheral band 5, said peripheral band 5 leaving a part of the septum 4, herein called outer surface 4a of the septum, directly facing the outside of the vial 1 , namely the outside environment.
  • the septum 4 is usually made of a material impermeable to gas and liquid and it seals hermetically the content of the vial 1 .
  • the septum 4 is also pierceable by the needle of an injection device intended to be filled by a dose of the product contained in the vial, said septum 4 being accessible to said needle via its outer surface 4a.

  • the distance between the distal face of the pierceable elastomeric piece and the outer surface of the septum may range from about 1 mm to about 5 mm : preferably this distance allows air flow to reach interface between the distal face of the pierceable elastomeric piece and the outer surface of the septum.
  • the adaptor of the invention allows piercing the septum of the medical container in favorable hygienic conditions multiple successive times while maintaining the sterility inside the medical container over its lifetime. Indeed, when the user decides to fill in the empty injection device provided on the adaptor with a dose of drug contained in the medical container, he simply secures the adaptor of the invention with its injection device on the medical container by means of the gripping member. Once the adaptor is secured on the medical container, the pierceable elastomeric piece of the adaptor is in contact, in particular in close contact, with the outer surface of the septum of the medical container. In addition, the needle of the injection device is stored in a chamber filled with decontaminated air.
  • introducing the needle of the injection device in the medical container implies that a sterile needle pierces first the pierceable elastomeric piece of the adaptor and then the septum of the medical container.
  • the piercing step therefore takes place in favorable hygienic conditions as no contaminant is introduced into the medical container, neither by the needle nor by any air that would enter the medical container during or after the product removal.
  • the needle is received in a decontaminated atmosphere at any time, namely in the storage and before use position of the adaptor, when the needle is in an inactive position, during the filling step of the injection device, when the needle is in its active state, and also in an end of use position of the adaptor, when the needle is back to its inactive position, once the injection device is filled with the adequate dose of product retrieved from the medical container.
  • the needle may not contaminate the septum or the product of the medical container, but it is also prevented from being contaminated between the end of use position of the adaptor and the moment the dose of product, for example a vaccine, now filling the injection device, is injected into a patient.
  • the injection device and its needle are enclosed into the adaptor from a storage state of said adaptor to the successive steps of dose of product removals. Therefore, the risk of misuse of the injection device is reduced. Furthermore, the adaptor of the invention not only allows a safe withdrawal step, but also a safe subsequent injection step.
  • the adaptor of the invention because it incorporates an injection device is intended for single use.
  • the user may repeat the piercing step of the multidose medical container described above with the needle of the injection device of a new adaptor until all the doses contained in the medical container are removed.
  • the septum of the medical container is therefore protected.
  • the air inlet of the adaptor of the invention with its second filtering system allows only decontaminated air to reach the distal face of the pierceable elastomeric piece which is in contact with the outer surface of the septum of the medical container.
  • the air sucked from the outside by the vacuum created inside the medical container by the removal of the needle arrives on the outer surface of the septum in a decontaminated state.
