Definitions

  • Coupling device for an adapter for a vial adapter for a vial, set comprising such an adapter and system comprising such an adapter
  • the invention relates to a coupling device for an adapter for a vial for a medical liquid, such an adapter, a set comprising such an adapter and a system comprising such an adapter.
  • a liquid containing an active ingredient can be introduced into a patient's bloodstream.
  • the liquid to be administered is often taken from a so-called vial with an injection syringe.
  • a vial is a liquid container whose opening is typically closed with a septum or an injection stopper that can be pierced with an injection needle.
  • vials are sometimes also referred to as “pierceable injection vials” or simply as “injection vials”.
  • the designations 'ampoule', 'phial' etc. are also used for vials if confusion with other types of ampoules and vials can be ruled out.
  • the liquid container of a vial is made of glass or plastic, for example. Its capacity can contain, for example, a single dose or several single doses of the liquid to be administered.
  • Vials are also filled with dry substance, since some drugs are not sufficiently stable in the dissolved state.
  • the dry substance is dissolved in a solvent placed in the vial (e.g. water or saline) before injection. solved. The solution is then removed from the vial in the manner described above.
  • Vials are also widely used in the laboratory, especially in the field of biotechnology, for manipulating liquids.
  • an adapter for the vial can be used. By connecting the adapter to the vial, a fluid connection to the interior of the vial is established, for example by a hollow mandrel or the like piercing through the septum.
  • the adapter has a fluid connection which is in fluid connection with the hollow mandrel and via which liquid can be removed from the vial or liquid can be supplied to the vial.
  • the fluid connection can be, for example, a connection for a plug-in connection, for example a connection for a Luer connection.
  • the connection preferably has a female Luer cone, since injection syringes and other devices for removing the liquid typically have a male Luer cone.
  • the luer connector can be of the "luer slip" type or of the "luer lock” type.
  • the fluid connection can, for example, also be a connection that has a different type of coupling element.
  • the adapter can be regarded as a transfer device for a medical liquid.
  • the adapter can be a gateway according to the ISO 22413:2010 standard.
  • an adapter has some key advantages. If the withdrawal of liquid from the vial or the addition of liquid to the vial is carried out using a hypodermic syringe fitted with a hypodermic needle, the septum of the vial does not have to be specially pierced. The piercing of the septum of the vial is prone to error, in particular it is often not at the right angle carried out and is associated with a risk of stab wounds. In this context, the use of an adapter is particularly advantageous if the septum would have to be pierced several times without the adapter.
  • the fluid port may be configured so that connecting to a hypodermic syringe or other device for removing or adding fluid is simpler, less prone to error, and less likely to cause injury than piercing a septum with a needle.
  • the fluid connection can be designed, for example, as a plug-in connection, for example as a female Luer connection.
  • the fluid connection can be designed in such a way that the connection to a hypodermic syringe or other device for removing or adding liquid is more secure than the connection via a needle inserted into a septum, which could easily be unintentionally pulled out again.
  • the fluid connection can be equipped with non-positive and/or positive holding means, for example.
  • the adapter offers the possibility of providing a special connection element for the respective application.
  • contamination of the environment must be avoided because contact with medical staff or other people is risky. This is the case, for example, with some cytostatics that are carcinogenic or mutagenic.
  • Such medicinal substances are therefore preferably handled in closed systems by means of so-called “closed system transfer devices” (CSTD).
  • CSTD closed system transfer devices
  • the adapter can have a connection structure suitable for this.
  • an adapter is advantageous or even necessary is the transfer of liquid between a vial and a fluid device, for example another liquid container, for example a container for an infusion solution. It can be particularly advantageous in such cases if a suitable or special for the fluid device trained adapter is traded as an accessory together with the fluid device.
  • Such adapters are known in the prior art, which can be irreversibly connected to the vials.
  • An "irreversible connection” is understood to mean a connection between two objects that cannot be detached, at least not without applying great force or damaging or destroying one of the objects.
  • Each of these adapters is designed for a specific size of vial and can only be used with vials of this size.
  • Vials typically conform to ISO 8362-1 and ISO 8536-1 standards.
  • the diameter of the neck of the vials of the various sizes is 13 mm, 20 mm, 28 mm and 32 mm (each within certain tolerances), whereby one of the two largest diameters mentioned is common in Europe (32 mm) and the other, for example, in the US (28mm).

  • the coupling device preferably comprises a base body which has an opening for receiving the vial, in particular a section of the neck of the vial.
  • the elastic structure is, for example, connected to the base body or formed in one piece with it.
  • Adaptation to the size of the vial is preferably effected by deforming or deflecting the elastic structure or a part of the elastic structure, depending on the size of the respective vial.
  • the deformation or deflection in this case is greater when connected to a larger vial than when connected to a smaller vial.
